ISSUE
The Planning Commission is being asked to consider a series of requests from SKB Environmental, Inc.
concerning a proposed expansion of its non-hazardous industrial waste containment facility (landfill) at
13425 Courthouse Boulevard into an area immediately east of the current landfill boundary. SKB currently
owns several parcels with a combined area of around 183 acres east of the landfill site, 113 of which would
be replatted into the landfill expansion area and the remainder of which would be retained for a future
business park or commercial development. The separate components of the application include the
following:
• Comprehensive Plan Amendment to change the future land use designation of 113 acres east of the
existing landfill from GI – General Industrial, LI – Light Industrial, and BP – Business Park to WM
– Waste Management.
• Zoning Map Amendment to change the zoning of the same 113 acres from GI – General Industrial
and AG – Agricultural to WM – Waste Management
• Preliminary Plat to plat the 113-acre expansion area as the SKB Landfill 2nd Addition. The plat will
also include a new public road and outlot for future business park development.
• Interim Use Permit revision to allow an expansion of the landfill into the 113 acres east of the
present facility, the moving of existing and proposed buildings in the northwest part of the landfill
into the expansion area, and expansion of the landfill into the northwest (former building) area.
4
The permit was last renewed by Rosemount in 2018 with no significant modifications to the previously
approved plans except for a minor reconfiguration of the distribution between construction and demolition
waste and industrial waste between two of the existing cells. The applicant is now requesting an expansion
of the existing operational parameters for the site which requires a modification of the approved interim use
permit.
Please note that prior City IUP reviews coincided with the timing of the facility’s required Minnesota
Pollution Control Agency (MPCA) permit (every five years). With its last approval in 2013, the MPCA
granted the SKB landfill a permit that is valid for 10 years. The 2013 MPCA permit therefore continues to
serve as the primary regulatory instrument for the site; however, the expansion will require a new MPCA
permit which will result in a new 10-year permit for the facility (through 2031). In 2021, staff recommended
that the City continue to review the permit every five years or in 2026, halfway through the MPCA
permitting cycle. Staff is recommending the original schedule be followed, which means only 4 years will
pass until the next review by the City. There is substantially more information required for the MPCA
permit; the City’s current review will focus primarily on any changes or issues that have occurred since the
last review. Dakota County also permits the facility and their permit process is on a two-year cycle; the
county will not issue a permit until both the City and State permitting process is completed.
BACKGROUND/HISTORY
In 1992, Union Pacific Railroad (USPCI) was approved to construct and operate an industrial solid waste
land disposal facility (landfill). The landfill was designed with ten containment cells with a total capacity of
2,520,000 cubic yards. In 1995, USPCI sold the landfill to Laidlaw, Inc. and in 1998 Laidlaw combined
with Safety Kleen Corporation. In 1997, municipal solid waste (MSW) ash from the Hennepin County
incinerator was permitted to be accepted at the landfill. In 2000, SKB purchased the landfill from Safety
Kleen. At that time, the landfill was permitted to accept industrial waste and MSW ash with a total landfill
capacity of 6,037,983 cubic yards covering approximately 70 acres of area with a permitted finish grade to
the 930-foot elevation (100 feet measured from 140th Street East).
In 2003, SKB requested and was approved for an expansion of their facility to add construction and
demolition debris to their approved fill material and an additional 9,320,608 cubic yards of waste (154%
increase) for a total permitted capacity of 15,358,591 cubic yards of waste. The approved expansion
permitted a total disposal area of 112 acres (60% increase) and finish grade to the 970-foot elevation (40%
increase).
In 2008, SKB requested and was approved for an increase the disposal capacity by 11,515,512 cubic yards
(75% increase) to a total capacity of 26,874,103 cubic yards. The expansion increased the permitted
disposal area to 151 acres (35% increase) and a finish grade of 1,010-foot elevation (29% increase). The
approved finish elevation is about 40 feet taller than the power lines on the site.
In 2012, SKB requested and was approved to accept source separate compostable material and process
that material with yard waste into compost.
In early 2013, SKB requested and was approved to deposit low level industrial waste in their
construction& demolition debris landfill cell. As part of SKB’s 2013 IUP renewal, the City approved an
5
increase the disposal capacity by 8,475,814 cubic yards (32% increase) to a total capacity of 35,349,917
cubic yards. The expansion also increased the permitted disposal area to 167.1 acres (11% increase) and a
finish grade of 1,060-foot elevation (28% increase). The approved finish elevation is about 90 feet taller
than the power lines on the site and 130 feet taller than the approved finish grade when the applicant
bought the site in 2000.
In 2014, SKB requested and was approved to modify the previously approved IUP plans for a non-ferrous
metal recycling facility to allow for a 4,200 square foot outdoor concrete waste depositing pad in addition
to the 14,976 square foot recycling building.
In 2018, the City approved a subdivision and Planned Unit Development (PUD) final site development
plan for 52 acres immediately east of the landfill site for three metals recycling buildings and a maintenance
shop. In addition, SKB proposed as part of the PUD development that trucks emptying loads at the
landfill would obtain fill material from the property to the east prior to departing from the landfill. The
waste exchange has been occurring on this property over the last two years. The PUD will be replaced by
the new interim use permit, if approved, and any recycling activity will be moved to the locations shown in
the IUP plans and incorporated into the overall landfill operations.
The most recent permit issued for the SKB Landfill was a renewal of the Interim Use Permit approved by
the City in November of 2018. The applicant did not request any revisions to the plans at that time, and
the City found all work performed in the previous five years adhered to the permit requirements. One
minor modification approved by the PCA and Dakota County, was the reconfiguration of waste materials
to be buried between cells three and five. Since this reconfiguration did not alter the approved final grades
in any manner, it did not require any modification to the previous permit.
The applicant did make a request in 2021 that is similar to the one before the Planning Commission.
Following the Planning Commission’s recommendation to deny the request due to impacts on adjacent
properties and neighborhood opposition, the applicant withdrew their request in order to work with the
adjacent land owners to acquire those properties. It is staff’s understanding that the applicant has reached
agreements with the various landowners, which is the basis for the resubmittal of the request.

SUMMARY
Landfill Configuration
The SKB landfill facility is currently divided into six (6) different cells that accept three (3) different types
6
of waste. Cells 1, 2, 3, and 6 are designed to accept industrial waste. Cells 1, 2, and 3 have a double liner.
Cells 1, 2, and 3 are approved as designed while Cell 6 was expanded by 16 acres as part of the 2013
approval. SKB proposed a different liner construction for Cell 6 from the double-liner constructed in
Cells 1,2, and 3 in 2013; this proposal was ultimately approved by the CPA and Dakota County after
approval of the interim use permit renewal that year. The approved design will offer similar or more
protection than the existing double-liner design.
Cell 3 contains a sub-cell (Cell 3M) that contains industrial waste containing PFCs from the 3M landfill
clean up from Washington County. Each cell has its own liner and leachate collection system. The Cell
3M was approved by Dakota County and the Minnesota Pollution Control Agency (MPCA) with its own
liner and leachate collection system. The leachate collected from Cell 3M is transported to the 3M
Chemolite incinerator in Cottage Grove and burned. Cell 3M is now closed and being covered with
traditional industrial waste.
Cell 4 is designed to accept mixed municipal waste (MSW) ash from the Hennepin Energy Recovery
Center (HERC) MSW incinerator in Minneapolis. The liner for Cell 4 is identical to that installed in Cells
1, 2, and 3. The operations of Cell 4 are similar to Cells 1, 2, and 3 other than SKB is removing and
recycling metals from the MSW ash.
Cell 5 is designed to accept construction & demolition (C&D) debris. Cell 5 has a single liner unlike the
industrial waste and MSW ash cells that have a double liner. In early 2013, SKB received approval from
the City and Dakota County to deposit industrial waste in Cell 5 that is no more than 25% of the soil
reference value (SRV). The SRV is the value by which the material is considered hazardous. The MPCA
allows industrial waste to be deposited into C&D cell provided that the industrial waste does not exceed
50% of the total cell volume.
SKB proposed one change to their vertical configuration in 2013 that was not approved until recently.
Specifically, the area between Cell 3 and Cell 5 (referred to as a “saddle”) was approved in 2008 to accept
C&D waste. As part of its 2013 permit, SKB proposed to draw an imaginary vertical line between Cells 3
and 5 and place industrial waste on the Cell 3 side of the line and C&D and low-level industrial waste on
the Cell 5 side of this line. SKB’s rationale was the industrial waste leachate will drain straight down into
the Cell 3 collection system and the C&D leachate will drain straight down into the Cell 5 collection
system. The City and Dakota County expressed concern about this design and some of the assumptions
that went into the proposal; however, the MPCA reviewed the modification and determined that the
proposed design changes will not create an increased risk to the environment and approved the minor
modification to the permit in August of 2018. The modification did not alter the overall permitted
capacity of the landfill, and only revised the overall mixture of different waste types in the facility with
more industrial waste and less construction and demolition waste. This change is reflected in the updated
plans included with the IUP revisions.
Proposed Expansion and Site Modifications
SKB Environmental approached the City in 2019 with concerns that, based on the projected volumes of
materials being deposited at the facility, it was nearing the capacity of certain cells on the site. In
particular, SKB has estimated that it has roughly 5 ½ years of capacity of demolition materials and a little
7
over 18 years to accept industrial waste. The MSW contributor ash cells will have a much longer period of
time remaining. In order to be able to plan for continued operation of the landfill, SKB proposes to
eliminate the planned PUD/metals recycling project previously approved by the City and instead use this
property as part of an expansion of the facility to the east. When the applicant purchased the PUD land, it
was part of a much larger land acquisition that resulted in SKB owning most of the land located east of the
landfill site between Courthouse Boulevard, Ehlers Path, and County Highway 42 (with the exception of a
12-acre agricultural property right at the Highway 42/55 intersection and a 3.25-acre residential parcel
along Highway 55).
The proposed expansion would add a new cell to the facility, Cell 7, that would accept industrial and
demolition waste streams similar to several of the existing cells within the landfill. This cell would be
located immediately east of Cell 5 at the eastern edge of the present operation, and tie directly into the
existing planned slope in this area. The resulting expansion would not raise the overall permitted height of
the landfill (1,060-foot elevation), but it would match the approved maximum height while pushing the fill
area further to the east. The expansion will create more usable space within the new Cell 7 area and
provide additional capacity in the slope that would now be filled between Cells 5 and 7. From a horizontal
perspective, the permit revision for Cell 7 will add 65.7 additional acres to the footprint of the landfill.
Vertically, the eastern expansion area will add 16,600,000 cubic yards of volume to the facility.
A secondary expansion area will add a smaller amount of additional waste storage volume within the
existing permitted landfill area as part of the applicant’s plan to move the shop, office, scale, and recycling
building to new locations in the eastern expansion area. By removing these buildings, SKB will be able to
add a new cell, referenced as Cell 8 in the plans, to the area east of Cells 1 and 4 at the western edge of
their property. Similar to the Cell 7 situation, the proposed Cell 8 expansion will not increase the
approved height of the landfill, and it will push the exterior slope outward to cover the former building
area. Cell 8 will add approximately 3 acres to the overall surface area of the landfill, with a corresponding
volume increase of 3,900,000 cubic yards of material.
One of the more significant changes proposed for the landfill with the revised interim use permit is the
construction of a new public street running north and south connecting State Highway 55 (Courthouse
Boulevard) and Ehlers Path (140th Street) at the far eastern edge of the expansion area. All access to the
landfill will occur from this street, and the existing private access to the State Highway will be eliminated.
The 2021 submittal included a road alignment that was straighter, but in an effort to alleviate some of the
concerns of the property owner to the north the applicant shifted the Highway 55 terminus of the new
road westward. That alignment doesn’t work with the turning patterns of the trucks entering and leaving
the site, so staff has asked the applicant to update the plans to revert the alignment of that road back to
what was originally proposed. The creation of this new road should help significantly improve safety along
the highway by moving all truck movements turning movements into and out of the site to the new
entrance. The new entrance will also provide much more stacking room for trucks and other vehicles by
increasing the length of the private driveway between the access point and truck weighing station.
Presently, there is limited space on the site for the stacking of vehicles entering the landfill, and there is
potential for a line of trucks to back up onto the highway right-of-way. Although trucks will still need to
turn from the highway to the new public road to access the site, the new intersection will be designed to
meet MnDOT intersection requirements and will provide room for turn lanes for both northbound and
southbound traffic. Finally, MnDOT is planning a large project this year to improve safety along the
Highway 55 corridor near the SKB site, and the City will be able to coordinate the construction of its
street with the other safety improvements.
The other site changes mentioned above will include the relocation of all existing buildings and structures
in the western side of the existing landfill to new locations within the northern portion of the expansion
area. In addition to moving these existing buildings, the applicant is also proposing to integrate the
recycling and maintenance buildings planned as part of the 2018 PUD approval within the revised interim
8
use permit. The proposed site plans show a series of buildings, including a maintenance building, storage
bunker, gem ash recycling building, secondary recycling building, office building, scales, and scale houses
near the northern property boundary (and Highway 55 right-of-way), all of which would be accessed via
the new driveway that extends back to the public north/south street. The new buildings will be phased
with other improvements within the expansion area and will be constructed over time rather than all at
once. In the meantime, the applicant plans to access the existing buildings through the same private
driveway once the existing Highway 55 access is eliminated. The updated interim use permit will require
SKB to close off its existing access once the construction of the public road is completed.
The other significant site changes include the construction of a series of storm water retention ponds
around the periphery of the existing landfill and proposed expansion area. The new or modified ponds
will be located within the far northwestern area, along the Highway 55 right-of-way, along the new public
street, and south of the expansion area along Ehlers Path. The latter ponding area will require the removal
of the existing trees and slope immediately north of Ehlers Path. Under the previous PUD development
plans the applicant would have preserved most of this slope; however, the landfill will substantially alter
the finished grade in the area and will leave limited space to accommodate storm water runoff from the
new grades. The applicant has inventoried all trees to be removed, and the project plans are subject to the
City’s tree protection and replacement requirements.
2018 Permit Update
The 2018 interim use permit renewal included an update on a few outstanding items within the previous
permit and incorporated updated conditions and requirements accordingly. A quick update on the status
of these items is as follows:
Wetland Filling and Mitigation. SKB previously received approval from the City and other permitting
agencies to fill wetlands in the southwest corner of the existing landfill area (Cell 6 area) through
the State’s wetland credit program. The grading work for this filling activity has commenced and is
continuing this summer. The wetlands permit is valid until November of 2021, and the applicant
will either need to complete all work specified in the permit by then or may need to apply for an
extension. Please note that the wetland credits associated with the work have already been
purchased and approved.
Grading/140th Street. Under previous permits, the applicant was given the ability to move some of
the required ponding area into the right-of-way for 140th Street. The City required modifications to
the grading plans with the 2018 permit to eliminate the use of any future City right-of-way for
storm water purposed. The revised grading and storm water management plans associated with
the present permit request must follow this requirement.
Vertical Expansion. The 2013 permit and subsequent 2018 renewal authorized an increase in the
overall size and capacity of the landfill, and specifically an expansion of the finished elevation to
1,060 feet (an increase of 50 feet from the 2008 permit). The approved landfill height will result in
a berm 230 feet higher than 140th Street East at the western edge of the site. This will also be 90
feet taller than the existing power lines and 130 feet taller (3.6 times) than the landfill that was
permitted for when SKB purchased the landfill in 2000. The overall plan creates a ridge 230 feet
tall along 140th Street East that slopes over the entire landfill to the north. Because 140th Street
increases in elevation as it moves the east, the overall difference in the finished landfill height in
comparison to the road will be somewhat less in the expansion area.
Recycling/Transfer Facility/Composting Site. The City authorized construction of the gem ash recycling
building with the 2013 permit, and this facility has been in operation for the past seven years. The
applicant has not constructed a transfer facility or source separated compostable material
composting site that were authorized under permits as far back as 2003. Staff expressed concern
9
about the amount of time that has passed since these specific components of the landfill were
approved and added a condition to the 2018 permit that the transfer and composting facilities
would no longer be included in any future permits beyond the next five years (until 2023). Should
the City issue a new, revised interim use permit for 2022, staff is recommending the deadline for
construction of these two facilities remain as stated in the last permit. The new IUP agreement
will be drafted to provision that if they are not constructed and operational by November 5, 2023,
they will no longer be considered allowed activities within the permit area. Staff is suggesting that
if the applicant does want to conduct these activities on site, they should make use of the permit
within the year or they can come before the Council in the future to again ask for the use and
modify the permit.
ISSUE ANALYSIS
The applicant’s submission materials provide a very thorough description of the operation and proposed
expansion plans. For the purposes of this review, staff will be focusing on those aspects of the plans that
will require modifications or further discussion with the City before implementation. The permit
approved in 2018 will serve as the basis for the new permit since the overall operation and activity on the
site will be substantially similar to the previous permit, just in new or different areas. Also note that while
the interim use permit will identify the types and locations of buildings to be constructed, the applicant will
need to follow the City’s site plan review process prior to construction of any new buildings on the
property.
MPCA/Dakota County Permits
In addition to the City, the applicant must secure permits for the landfill expansion from the Minnesota
Pollution Control Agency (MPCA) and Dakota County. The facility cannot operate without these permits
in place, and staff is recommending a condition that ties the state and county permitting to the City’s
interim use permit process. The MPCA permit is valid for 10 years while the Dakota County permit is
valid for two years. Staff is not aware of any past issues associated with either of these permits and will
continue to reach out to these agencies if any issues or concerns arise within the landfill operation.
Comprehensive Plan Update
The landfill expansion area is presently guided for either GI – General Industrial, LI – Light Industrial, or
BP – Business Park land uses in Rosemount’s 2040 Comprehensive Plan. None of these land use
categories allow for a landfill use, which is restricted to a special WM – Waste Management designation in
the Plan. The existing landfill is guided for this land category, which is intended to “accommodate the
need for management of waste generated by society while regulating the inherent environmental problems
associated with waste management”. Although the area presently guided for GI land uses does allow for
the metals recycling buildings and other industrial activity, it does not allow for the waste management
activities proposed in the expansion area. The WM category allows the landfill use in addition to recycling
centers and related waste management activities (i.e. the office, lab, maintenance, and other uses).
Staff is supportive of the proposed land use amendment to expand the WM district partially because the
proposed public street construction and existing roads around the site will help establish a defined limit fir
the landfill with limited opportunities for further expansion outside of these borders. While the
amendment will expand the overall footprint of the landfill, it will not result in a significant increase in
activity since the applicant intends to maintain the current volume of material entering the facility on an
annual basis. The expansion further provides opportunities to improve operations by moving access to a
new public road and avoiding direct turning movements the adjacent state highway into and out of the
facility. The WM expansion will leave room for additional business park development in the area and will
still provide a gradual transition from the heavy industrial uses further to the north to the planned
residential uses south of Highway 42.
Storm Water Management.
10
The City has completed its initial review of the proposed storm water plan associated with the revised
interim use permit plans. The City’s consulting engineer has provided comments concerning the plan, and
some modification will be needed to meet all applicable City standards. One of the areas that does need
some attention is the proposed retention basin located directly north of Ehlers Path. The current design
acts as a dam due to the existing slope and the placement of a pond within this slope. This grading of this
area will need to be revised in order to comply with Minnesota dam safety requirements. The overall plans
will must be revised to address all comments from the Engineer. The overall storm water plan was
previously updated to remove any ponding from the 140th Street right-of-way, and the proposed plans will
conform to this requirement.
Utilities
The site is not presently served by pubic sanitary sewer, but it is partially within the 2030 MUSA (urban
service boundary). Trunk water main is presently located within the Highway 55 right-of-way and service
is stubbed into the site at the current private entrance. Trunk water main will need to be extended further
to the east to serve the proposed buildings. The City Engineering is also requesting that this main be
extended along the northern boundary of the expansion area and within the new north/south public street
right-of-way connecting Highway 55 and Ehlers Path. The applicant’s plans must be updated to address
this requirement because they presently show the trunk watermain terminating near the proposed
maintenance and recycling buildings. As new lots are platted within the City’s urban service area,
developers are required to extend services to their project/property boundaries.
Because City sewer services are still a considerable distance to the subject site, the applicant is proposing to
serve the new buildings with a new private sewage treatment system. Given the relatively limited need for
public sanitary sewer services on the site, staff is supportive of a private system, but only until the public
service is extended to the area. Staff is recommending a condition of approval that requires all buildings
on the site to connect to public sanitary sewer service within one year of this service being extended and
available to the site. The City will plan on a service connection in the location shown on the site
development plans.
Gr ading – Excavation Activities
As part of the City’s approval of the PUD for recycling activities in 2018, the applicant requested the
ability to perform a waste exchange operation with its truck drivers. The approved grading plans for the
PUD therefore show a significant amount of gravel material being removed from the site and made
available to trucks leaving the site after depositing their waste products into the landfill. This excavation
activity has been occurring over the last several years in accordance with the permit. The City ultimately
approved the lowest grade that could be mined prior to construction of any buildings within the project
area, which was approximately 18 feet below the current (at the time) grade.
With the request to now convert this area to be part of the active landfill area, the previous grading
restrictions will be replaced by the proposed landfill plans. All the cells within the landfill area created by
first excavating down to a base elevation much lower than the surrounding grades, placing a liner down to
collect and prevent waste leachate from entering the ground water, and then placing waste material in the
lined pit until it reaches the planned maximum elevation (which is limited based on the final slope to the
peak of the landfill). The landfill interim use permit would allow excavation to a much lower elevation
than was planned with the PUD waste exchange program, which in some portions of the landfill
expansion area could be up to 50 feet lower. All cells within the landfill include a base, excavation level in
addition to a final, covered elevation that will be reached upon closing of the cell. The ability for the
applicant to go further down is limited by the current sub-surface conditions and the boundaries of the
site. In addition, the amount of surface fill is limited for similar reasons since the applicant is required to
maintain a 25% slope for the final vegetative cover.
Access/Traffic/New Public Road
11
Previous sections of this report discuss the proposed realignment of access to the landfill from the present
private entrance along State Highway 55 to a new public road along the east side of the expansion area.
SKB has agreed to pay for construction of the new public road and will dedicate right-of-way with the
SKB 2nd Addition plat; however, they have also asked that the City assume responsibility for design and
construction of the road. The City will be working on the design for this road, and it expects that the
required subdivision agreement will address the City and applicant’s responsibilities concerning
construction of the road. The proposed plat provides 66-feet of right-of-way for the new public street;
staff is recommending that this be increased to 80 feet because it is planned to be a major connection
point between State Highway 55 and County Highway 42 in the future.
From a traffic perspective, the proposed expansion is not expected to generate any additional truck traffic
beyond the current levels. The applicant has noted that the additional landfill space is needed to give them
more time to operate the facility, not to give them the ability to process more waste on a daily basis. With
the construction of a new public road and removal of direct access to the landfill from Highway 55, the
overall safety for both the trucks entering the exiting the facility and the daily drivers along the highway
should improve considerably under the proposed development plans. The timing of the interim use
permit revision is also beneficial since MnDOT is planning on making safety improvements along this
corridor that can be timed to match the closing of the current entrance.
One of the major areas of focus during the most recent public review of the landfill and PUD area
involved the number of trucks that are expected enter and exit the facility on a typical operational day.
With past reviews, SKB has indicated that there are between 200 to 1,000 trucks using the facility each day,
with some variability based on the season, construction activity in the region, and other factors. While this
amount of traffic can be accommodated by the major highways around the site, MnDOT did require
specific improvements at the private entrance in conjunction with the construction of additional recycling
buildings on the site. Without the private connection, these improvements are no longer necessary;
however, the design of the new public road connection and intersection (which SKB’s trucks will be using)
will need to incorporate all of MnDOT’s standards and requirements.
During previous reviews, the City has asked SKB to submit route maps of truck circulation within the
facility and off-site, with the potential to require further information concerning traffic counts and updated
route maps when deemed necessary in the future. The applicant should provide updated circulation maps
for the new access and building areas; these maps can be provided at the time the new buildings are
constructed.
Wetland Update
The filling of the wetlands is underway and will continue throughout this summer. If the applicant is not
able to complete this work before November of this year, they will need to request an extension of the
wetland mitigation permit.
Parks and Trails
Both the Met Council and Dakota County have commented that the interim use permit plans do not
identify or reserve space for the planned future regional trail corridor through this area. Under previous
permits, the applicant agreed to provide a 30-foot wide easement outside of the dedicated right-of-way
along Ehlers Path/140th Street to accommodate the future regional. Staff is recommending that the
proposed plans be revised to accommodate a trail easement along Ehlers Path/140th street consistent with
those previous approvals. The trail is expected to cross Highway 55 near its intersection with County
Highway 42, and it will eventually provide a connection between the developed and developing portions of
12
Rosemount west of State Highway 52 and the Mississippi River Trail and Spring Lake Park Preserve.
With the platting of land for new building construction and expansion of the landfill, the applicant will
need to pay fees in lieu of land dedication based on the City’s current fee schedule. SKB previously paid
these fees for the portion of the landfill expansion area that was platted with the metals recycling project.
The new fees will therefore be based only on the 52.41 acres platted as Lot 1, Block 1 of the SKB
Rosemount 2nd Addition subdivision. This fee is established at $50,000 per acre for an industrial
subdivision.
Site Plan Review Process
The proposed development plans do not include detailed plans for each of the future buildings, and
instead show a general location and arrangement for these structures within the facility. Prior to
construction of any new buildings, the applicant will need to follow the City’s site plan review and
approval process, which means the Planning Commission will have the opportunity to review additional
details concerning each building before it is constructed. The buildings will need to conform to the City’s
building standards and the standards established for structures on the landfill site under previous permits.
Staff will review other site requirements, including building height, setbacks, parking, and landscaping with
future permit submissions. The interim use permit will establish the overall plan for construction of future
buildings, and future site plan approvals will need to be consistent with these plans.
Tree Preservation and Landscaping
The applicant has previously prepared a landscape plan associated with the metals recycling/PUD
development area, and was short of the number of trees require for a GI – General Industrial project. The
City accepted a cash payment in lieu of 227 tree that would have otherwise been required on the plans.
With the elimination of the PUD and rezoning back to Waste Management, the overall landscape numbers
will look different than were previously calculated and paid on the property. Because the City does not
specify a specific planting requirement for the WM district, the applicant has calculated the landscaping
requirements based on the “disturbed area” of the site rather than the entire landfill expansion area. There
are also substantially more trees being removed from the property to provide room for storm water
management than under this previous plan. The tree preservation calculations provided by the applicant
indicate that they would need to replace 1,145 caliper inches of trees to meet the City’s requirements, but
they have also requested flexibility from this requirement because so many of the impacted trees are
considered non-native or undesirable for this region.
Staff will need to review the previous approvals on the site and have some additional conversations with
the applicant to determine how to best calculate the landscape requirements and any additional plantings
that may be required to meet the City’s standards. The landscape plan that has been prepared does
provide a robust number of trees around the perimeter of the landfill expansion area, and has been
updated from the 2021 submittal to now contain 730 trees and 399 shrubs.
Final Plat
SKB has submitted a preliminary plat request in conjunction the interim use permit application, and it will
need to receive approval for a final plat from the City before proceeding with development of the landfill
expansion. In conjunction with a final plat, staff will be drafting a subdivision agreement to clarify the
expectations and requirements for construction of the new public road and water services to the site.
Environmental Assessment Worksheet (EAW)
The proposed landfill expansion meets the threshold for a mandatory EAW, and this environmental
review process was completed earlier this year. The EAW and comments on it were reviewed in
accordance with Minnesota Rules 4410.1700 to determine if the project has potential for significant
13
environmental effects.
The City of Rosemount received seven comments concerning the SKB Environmental EAW within the
30-day comment period, and all are included as part of the record and decision-making document
approved by the City Council in May of this year. None of the comments received indicated the potential
for significant environmental impacts (these comments were described in the adopted findings of fact).
The response from the Met Council did include an indication that the EAW was incomplete or missing
data; however, the City and project proposer participated in a follow-up meeting to discuss the comments
with Met Council staff and determined that the comments could be addressed as part of the findings of
fact. SKB Environmental has agreed to continue working with the Met Council to address any future
regulatory changes concerning disposal of landfill leachate into the regional wastewater system and
treatment of PFAS pollutants in particular. The City also committed to identifying a regional trail corridor
on future development plans to address another aspect of the Met Council’s comments.
Revised IUP Agreement
The primary City regulatory document for the SKB landfill has been the IUP Agreement approved with
the original permit and subsequent revisions at the end of each five-year renewal period. Staff is not
recommending any significant changes to the present agreement document (included as one of the
attachments to this report), but staff is planning to incorporate any conditions added during the present
review that go above and beyond those presently included in the agreement. A revised agreement will be
presented to the City Council along with the Planning Commission recommendation.
Engineering Review
The City Engineer has provided the attached review document concerning the interim use permit request,
including a separate document focusing on the storm water management plans for the site. Compliance
with these comments has been included as a recommended condition of approval. The applicant will need
to pay development-related fees, including water trunk area and storm water area charges based on the
City’s current fee schedule. These fees will be calculated for Lot, 1, Block 1 of the subdivision, with future
payments due once the outlot is platted into buildable lots.
RECOMMENDATION
Staff recommends that the Planning Commission recommend approval of the Comprehensive Plan
Amendment, Zoning Map Amendment, Preliminary Plat, and Interim Use Permit to allow SKB
Environmental to expand the SKB Landfill into an adjacent 113 acres of land immediately east of the
present facility with the conditions provided in the draft motions at the beginning of this report.

Reference: SKB Environmental Application for the Proposed Landfill Expansion on the property
located immediately east of the current SKB Rosemount Landfill site – 13425
Courthouse Boulevard
Dear Mr. Nemcek,
On behalf of SKB Environmental, Inc. (SKB), enclosed are the following applications to support expansion
of the SKB Rosemount Landfill:
•Comprehensive Guide Plan Amendment Application
•Rezoning Application
•Preliminary Plat Application
•Final Plat Application (to be submitted at later date following approval of preliminary plat)
•Interim Use Permit Application
The Applications are being submitted because SKB is proposing to increase the industrial waste and C&D
landfill capacity by expanding onto approximately 163 acres of adjacent land immediately east of the
current landfill disposal area. It is important to note that a previous application for this project was submitted
to the City on June 1, 2021. An Environmental Assessment Worksheet (EAW) was also completed for this
proposed landfill expansion. The Findings of Fact, Conclusions, and Record of Decision was issued on May
13, 2021 and found that the proposed project does not have the potential for significant environmental
effects to trigger the need for an Environmental Impact Statement (EIS).
The project came before the City of Rosemount Planning Commission on July 13, 2021 and that meeting,
the Planning Commission recommended that the City Council approve the Comprehensive Guide Plan
Amendment, Rezoning Map, Preliminary Plat (with conditions), and the IUP (with conditions) by a 7-0 vote.
Due to a meeting notification error, the project came before the Planning Commission a second time on
August 10, 2021. Due to concerns raised by the neighbors about the project at this second meeting, the
Planning Commission voted 6-0 to deny that the City Council approve the above referenced applications
and encouraged SKB to work through project details with the neighbors. These applications to support
expansion of the landfill are a result of SKB working with the City and neighbors.

Reference: SKB Environmental Application for the Proposed Landfill Expansion on the property located immediately east of the current
SKB Rosemount Landfill site – 13425 Courthouse Boulevard
The attached applications have incorporated modifications to the June 1, 2021 submittal based on
numerous discussions and meetings with the City and neighbors. The modifications have resulted in the
landfill expansion area being approximately 119.1 acres in size, while the remaining 43.9 acres is being
designated for business park development. In the previous June 1, 2021 application, the landfill expansion
area was 113 acres while the remaining proposed business park was 50 acres. The layout of the proposed
City road has also been modified based on discussions with the City and neighbors.
SKB believes this submittal addresses the concerns of the neighbors as well as the City’s long-term vision
for development of this area. The existing landfill is located within an area of the City that is classified as a
“Waste Management Area” on the City’s zoning map. The City’s zoning code for the Waste Management
District state that this district is intended to accommodate waste management, disposal, and recycling
operations and that uses within this district shall be permitted by an Interim Use Permit. The approximately
119.1 acres of the 163 acres of adjacent land will also need to be rezoned to reflect WM “Waste
Management Area”. The 43.9 acres east of the new proposed city road, guided as a future business park to
be developed according to the City’s Zoning and Comprehensive Plan.
Attached again in support of this application are the following:
1.Comprehensive Guide Plan Amendment Application
2.Rezoning Application
3.Preliminary Plat Application with Preliminary Plat Drawing
4.Interim Use Permit Renewal Application
5.Project Description and Operations narrative with Preliminary Site Construction Plan Drawings

Introduction
Project Number: 227702665 1-1
INTRODUCTION
1.1 PURPOSE
SKB Environmental, Inc. (SKB) respectfully submits to the City of Rosemount this Project Description and
Operations Narrative in support of the Comprehensive Guide Plan Amendment Application, Rezoning
Application, Preliminary Plat Application, and an Interim Use Application for the proposed expansion of
the SKB Rosemount Industrial Waste Disposal Facility. The Facility is located at 13425 Courthouse
Boulevard within sections 19, 20, and 29, Township 115N, Range 18W, Dakota County, Minnesota.
There are currently multiple disposal areas at the Facility that receive different waste streams, which
include demolition debris, industrial waste, and municipal solid waste combustor ash disposal. The
expansion areas would receive only industrial waste and construction and demolition debris (C&D). SKB
is proposing to increase the industrial waste and C&D landfill capacity by expanding onto 119.1 acres of
adjacent land immediately east of the current landfill disposal area as well as in the area where the
current office and scale are located. The two expansion areas will together provide approximately
21,200,000 cubic yards of disposal capacity. Although detailed development plans are not included as
part of this project, a future business park is proposed for development on 43.9 acres east of the landfill.
The Preliminary Plat Drawing is titled – SKB Rosemount 2nd Addition and is provided with the Preliminary
Plat Application. The legal description of the property for landfill expansion is on the Preliminary Plat. The
proposed eastern landfill expansion is designated as Lot 1, Block 1. There is also an Outlot A detailed as
part of the plat. The Preliminary Plat Application have been prepared in accordance with the applicable
City codes.
The expansion project will provide for a new site entrance/exit off of a new City road to be designed and
constructed by the City of Rosemount (City) which connects to Ehler’s Path. The new entrance/exit is
intended to improve traffic safety on Highway 55. In an effort to support environmental initiatives
consistent with SKB and City values, the proposed landfill development will allow SKB the opportunity to
continue to make investments in and expand its recycling operations. SKB will relocate the facility
sustainability campus which will include buildings to serve recycling activities at the landfill. The Gem Ash
building and storage bunker currently exist at the existing landfill and will be relocated to make room for
when Cell 8 is built. The recycling and maintenance buildings approved as part of a previous PUD and
will be relocated as part of the expansion. There is no change to previously approved activities only
relocation.
Preliminary Site Construction Plans for Site Improvements detailing the proposed landfill expansion are
provided in Appendix A.
It should be noted that this project came before the City of Rosemount Planning Commission in July and
August 2021. Due to concerns raised by the neighbors regarding this project, the project was denied and
it was requested that SKB work through project details with the neighbors. This narrative report details
and supports expansion of the landfill as a result of SKB working with the City and neighbors. An EAW

Introduction
Project Number: 227702665 1-2
was also completed for this project with the Findings of Fact, Conclusions, and Record of Decisions
issued on May 13, 2021 and found that the proposed project does not have the potential for significant
environmental effects to trigger the need for an Environmental Impact Statement.

transition between planned use categories. The landfill and proposed business park meet the spirit and
intent of the following goals and objectives as referenced in the Rosemount 2030 Comprehensive Land
Use Plan:
•Chapter 4 – Economic Development. This project meets goal 2 to expand Rosemount’s
employment base to provide jobs that can support an entire household (p. 27). Grow Rosemount
by attracting and supporting businesses.
•Chapter 6 - Environment and Natural Resources. This project meets goal 4 to encourage
activities that reduce the consumption of finite resources and ensure there are opportunities to
reuse or recycle natural resources (p. 43).
•Chapter 7 – Land Use. This project meets goal 7 to encourage and promote sustainable
development, green building, and resource conservation (p.80).
SKB ENVIRONMENTAL PROPOSED LANDFILL EXPANSION
Introduction
Project Number: 227702665 1-3
1.4 BENEFITS TO THE CITY
In order to continue providing a valuable service to the region and as part of long-term business planning,
SKB is proposing to expand the SKB Rosemount Industrial Waste Disposal Facility (the Facility). The
proposed development will benefit the City of Rosemount in the following ways:
•Facilitate safe traffic conditions on Highway 55 by providing new City road and site access point
•New Business Park
•Continued Host Fees
•Local employment
•Park dedication fees
•A more rigorous cell capping schedule to reduce the amount of leachate generated.
The above benefits offered to the City by the landfill expansion is provided in more detail in the following
text.
As the expansion moves east within the site, a new access will be provided on a new north/south public
street located off of Ehler’s Path and west of CSAH 42. This new road will provide a new entrance to the
landfill expansion area as well as an entrance to the future business park. The existing access to TH 55
will be closed when the new access is constructed. The new proposed road will be designed by the City
to accommodate traffic volumes from both the landfill and the future business park and provide for
increased vehicle queuing capacity at the landfill. These proposed traffic improvements associated with
the landfill and business park development will help fulfill safety improvements on TH 55 that are needed
to accommodate existing and future traffic volumes.
A new business park is proposed for 43.9 acres to the east of the 119.1- acre landfill expansion area. The
business park will allow for the expansion of commercial and industrial type businesses within the City of
Rosemount and generate additional property tax revenue as well as provide for jobs.
The landfill has paid host fees to the City of Rosemount for many years. The amount of host fee paid to
the City by SKB in 2021 was $2,356,051.04. The continued payment of host fees as part of the landfill
expansion will continue to help reduce the tax burden on the City as well as fund various community
development projects that City residents can benefit from.
The landfill expansion will continue to provide jobs for the 23 current employees at the landfill. In addition,
the landfill expansion will result in the payment of park dedication fees for the 119.1- acre expansion area.

General Project Description
Project Number: 227702665 2-1
GENERAL PROJECT DESCRIPTION
2.1 SITE LOCATION AND DESCRIPTION
Both USGS and Aerial site location maps are presented as Figures 1 and 2, respectively. A list of
adjacent property owners within a 350- foot radius of the site is provided in Appendix B. The proposed
facilities for the landfill expansion are proposed to be served by city water and sewer in the future upon
the extension of sanitary sewer by the City.
The soils beneath the site consist predominantly of sands and gravels. This information is based on soil
boring logs completed along the eastern boundary of the landfill as well as a site investigation completed
in July 2015. Soil boring logs and a boring location map from the July 2015 investigation are provided in
Appendix C.
2.2 GENERAL FACILITY DESCRIPTION
The existing SKB disposal facility in Rosemount consists of approximately 237 acres of which 170 acres
is designed to accept non-hazardous industrial wastes, mixed municipal solid waste incinerator ash, and
non-hazardous debris resulting from construction and demolition, including asbestos into the landfill.
Other permitted activities at the site include a recycling/processing building, transfer station, and compost
facility. The landfill is located at 13425 Courthouse Boulevard within sections 19, 20, and 29, Township
115N, Range 18W, Dakota County, Minnesota.
The landfill has been in operation since 1992 and was purchased in 2000 by SKB who has been
operating the facility since that time. An initial Interim Use Permit (IUP) was issued by the City for the
landfill when the facility opened in 1992, and SKB assumed the obligations of the IUP at the time it began
operating the facility in 2000. The landfill has an existing IUP from the City of Rosemount that was
renewed by the City on November 5, 2018 and expires on November 5, 2023. The landfill operates under
Minnesota Pollution Control Agency (MPCA) solid waste permit number SW-383 (available upon request).
The MPCA reissued SW-383 for the landfill in 2014 with a ten-year term until 2024. The landfill also
operates under various solid waste facility licenses issued by Dakota County.
The existing landfill is located within an area of the City that is classified as a “Waste Management Area”
on the City of Rosemount’s zoning map. The City’s zoning code for the Waste Management District state
that this district is intended to accommodate waste management, disposal, and recycling operations and
that uses within this district shall be permitted by an Interim Use Permit. The proposed project will expand
onto 119.1 acres of adjacent land to the east and support the existing operations and maintenance of the
SKB Rosemount facility. The eastern expansion area zoning will need to be changed to reflect WM –
Waste Management area. Again, the northwest expansion area lies within the existing landfill which is
zoned WM.
It is important to describe the existing landfill site and the operations, since SKB is proposing an
extension of these with the industrial waste landfill expansion onto the adjacent eastern property.
SKB ENVIRONMENTAL PROPOSED LANDFILL EXPANSION
General Project Description
Project Number: 227702665 2-2
The drive and parking areas in and around the proposed buildings will be mainly bituminous paved with a
small area of Class 5 near the maintenance building. The Class 5 in this area is needed to adequately
support the types of heavy equipment that will be around the maintenance building. There is
approximately 305,000 square feet of bituminous paving proposed for the landfill expansion development.
The landfill expansion area will be accessed via an entrance/exit gate off of the proposed new City road.
The landfill expansion development has sufficient area to allow for the safe passage of all vehicles.
2.3 TREE INVENTORY AND PRESERVATION PLAN
A tree inventory and preservation plan were completed and is provided in Appendix D of this Project
Description Narrative. As identified in the EAW completed for this project, SKB will clear and grub trees
outside the prime nesting season of the Loggerhead Shrike, from August through March, to avoid adverse
impacts to this State and Federally listed endangered species. The calculations for the number of trees to
be removed are also provided in the Tree Inventory and Preservation Plan provided in the Preliminary
Construction Plan Drawings (Appendix A).
2.4 SITE GRADING
Similar to the existing landfill operations and as required by MPCA rules, the proposed eastern industrial
waste landfill expansion will be developed in phases or cells. As shown on the IUP Plan Sheets provided
as Attachment 4 later in the IUP memorandum section of this submittal, the proposed eastern expansion
will be identified as Phase 7 and be developed with three (3) cells. Due to the size of the northwestern
expansion, it will be developed in one phase and identified as Phase 8. The Phase 7 cells, and estimated
waste capacity (including final cover) of each cell, and Phase 8 are as follows:
Phase 7 - Eastern Expansion:
Cell 7A - 5,800,000 Cubic Yards
Cell 7B - 5,600,000 Cubic Yards
Cell 7C - 5,900,000 Cubic Yards
Total Phase 7 ~ 17,300 000 Cubic Yards (includes final cover requirements)
Phase 8 - Northwestern Expansion:
Cell 8 - 3,900,000 Cubic Yards
SKB expects construction of new industrial waste cells or closure of cells once every two to five years for
approximately three to four consecutive months at a time.
Upon completion of landfill development, the site will be final covered. The final cover is designed to
prevent precipitation from entering the waste. SKB is committed to a more rigorous cell capping schedule,
which will reduce the amount of leachate generated. The MPCA approved final capping system from top
down is as follows:
•6” topsoil and vegetative cover
•30” cover soil
•A geocomposite drainage net
SKB ENVIRONMENTAL PROPOSED LANDFILL EXPANSION
General Project Description
Project Number: 227702665 2-3
•40 mil LLDPE geomembrane
•12” buffer soil or intermediate cover layer
As final cover technologies advance, SKB may substitute, with MPCA and Dakota County approval, an
item in the approved final cover profile with an equivalent or superior alternative.
Slopes on the final cover system will range from 2 percent on top to 25 percent on the side slopes. The
highest elevation of the eastern expansion area will be approximately 1060 ft. NGVD where it ties into the
highest elevation of the existing landfill. The existing land surface is approximately 900 to 908 ft NGVD.
The construction of the expansion area will increase the height of the existing land surface by
approximately 160 ft. The proposed final contours were designed not to maximize capacity, but rather
improve the overall aesthetics of the landfill. Stormwater runoff from the landfill site will be controlled on-
site by strategic placement of drainage swales, erosion control mats, and riprap, concrete, or gabion
downslope structures. Runoff will be directed to a perimeter ditch system that takes surface water to the
sedimentation ponds located around the site.
Stormwater run-on into the industrial waste disposal area will be prevented by site grading. Run-off from
off-site and undeveloped areas will be collected in external perimeter channels and natural drainage
pathways and routed away from the site.
Appropriate native seed mixes will be evaluated by SKB for use in open space areas around the
stormwater ponds and other setback areas.
2.5 LANDSCAPING
Proposed landscaping plans were prepared by a landscape architect and presented in Appendix A-
Preliminary Site Construction Plans. The required calculations with regards to landscaping are also
provided on Plan Sheet No. L-101. Landscaping along the new site access road and site parking area are
detailed on the Landscaping Plan Sheets. Based on City code requirements, calculations performed
indicate that the number of trees required for development is 730 trees. The proposed landscaping plans
provides for 730 trees. As shown on the Landscaping Plan Sheets, the new proposed trees adequately
screen the proposed buildings and site operations on all sides. SKB has provided for foundation plantings
around the proposed parking areas and around the proposed buildings. SKB has provided a total of 399
foundation plantings to meet the city requirements of 301 where planting space is available.
2.6 SITE UTILITIES
As previously stated, the proposed landfill expansion and associated buildings will be served by City
sewer and water. Sanitary service is proposed at 6-inches and is to connect at a future City trunk line at
140th Street. Future watermain and sewer connection are based on the City East Side Study Plan and
input from City staff. The proposed utility plan has been developed based on previous conversations and
meetings with the City engineer and staff as part of previous PUD applications for this area. A proposed
utility plan is provided on the Plan Sheets in Appendix A.
SKB ENVIRONMENTAL PROPOSED LANDFILL EXPANSION
General Project Description
Project Number: 227702665 2-4
With regards to water service, a 6-inch water service connection is proposed for the landfill expansion
development. The 6-inch water service will connect to a future 16-inch watermain in the northwest corner
of the property. The proposed recycling building will not have potable water. The water service extension
is based on a meeting with the City Engineer and is detailed on Plan Sheet C-401 in Appendix A.
To accommodate any uncertainties with the City’s schedule and plans to extend the city trunk sewer, SKB
is proposing a subsurface sewage treatment system (SSTS) for sanitary services for the landfill
expansion including the office/shop building and recycling buildings on the sustainability campus. The
septic system design will conform with city standards to provide adequate separation between the drain
field and the groundwater. SKB will connect to the municipal sanitary sewer when extended to the site.
A site and soil assessment following methodologies laid out in Minnesota Rules Chapter 7080 and Title 9,
Chapter 6 of the City of Rosemount Code of Ordinances was conducted at the proposed SSTS location
on November 19, 2020. State code sets forth two methods for sizing a soil treatment area: utilize detailed
USDA soil profile descriptions and/or in-field hydraulic percolation test (MN 7080.2150 Subp. 3 Tables IX
and IXa). Rosemount SSTS ordinance requires using both methods and to use the more restrictive sizing
factor of the two.
The site assessment was performed by a licensed Professional Soil Scientist and MPCA-certified SSTS
Inspector. Five soil borings were conducted to a depth of 70 inches within or near the proposed drainfield
locations. The observed soil profiles were consistent with one another and featured approximately 24
inches of clay loam and loam over sand and coarse sand. Coarse fragments did not exceed 35% in any
observed soil horizon. No redoximorphic features or other indicators of seasonally saturated soil were
observed within any boring. The observed soils were consistent with Web Soil Survey, which indicates
the presence of well-drained sandy outwash subsoils under a mantle of loamy glaciofluvial deposits.
Saturated hydraulic conductivity (ksat) testing was conducted using a constant head permeameter
(Amoozemeter). Two test attempts were made within the sandy receiving soils below 24 inches. In both
cases, the test holes drained rapidly and thus conducting measurements with the Amoozemeter was not
feasible. SSTS site assessment information is provided in Appendix E.
Per state and local codes, a standard SSTS requires at least 36 inches of vertical separation from
seasonal high groundwater. The five soil observations did not feature any indicators of seasonal soil
saturation above 70 inches. This site is suitable for a subsurface trench or bed system with a maximum
depth of 34 inches. Using the tables from MN 7080.2150 Subp. 3, the USDA soil profile descriptions
generate a more restrictive soil loading rate than the in-field ksat testing. Per City code, the more
restrictive result is to be used for determining the soil loading rate. The Table IX loading rate for sand or
coarse sand with less than 35% coarse fragments is 1.2 gallons per day per square foot. However, MN
7080.2150 Subp. 3(L) states that drainfield distribution media cannot be placed directly on sandy soil with
a percolation rate faster than 0.1 minutes per inch. It is Stantec’s recommendation that the drainfield
distribution media be placed within the clay loam soils immediately above the sandy outwash, and the
drainfield be sized using a 0.45 gallons per day per square foot loading rate.
The design wastewater flow (DWF) was computed based off MN Rules Chapters 7080 – 7083 and
Dakota County Subsurface Sewage Treatment System (SSTS) Ordinance 113 using MN Rules
7081.0130, Subpart 1, Table I Estimated Design Sewage Flow from Other Establishments. Specifically,
SKB ENVIRONMENTAL PROPOSED LANDFILL EXPANSION
General Project Description
Project Number: 227702665 2-5
the DWF is based on the number of employees and people visiting the office. The DWF is used to size
SSTS components including the septic tank, dose tank, and soil dispersal system. Table 2-1 below
summarizes DWF calculation.
Table 1: Design Wastewater Flow Calculation
Flow Generator No. Flow/Generator
(gpd) Total Flow (gpd)
Employee 23 18 414
Office Visitor 6 13 78
Wastewater Flow Subtotal: 492
Total Design Wastewater Flow: 500
The proposed SSTS to serve the office would provide primary treatment prior to being dispersed to the
soil. Raw sewage from the building would be conveyed to a septic tank equipped with an effluent screen
to prevent large, suspended solids from flowing downstream to the dose tank. The dose tank would
deliver settled wastewater to the absorption bed from submersible pumps within the tank. Pumps and
floats would be controlled by a main control panel located adjacent the dose tank. The soil absorption bed
would maintain a minimum vertical separation to seasonally saturated soil of 36-inches and be sized at a
0.45 gpd/ft2 soil loading rate. Therefore, the total minimum infiltrative area required would be 1,115 ft2.
Effluent would be pumped to the soil dispersal area and distributed evenly by a network of PVC
distribution laterals within a drainfield rock bed.
2.7 EROSION CONTROL PLAN
It is also important to note that the existing NPDES stormwater permit and associated Storm Water
Pollution Prevention Plan (SWPPP) for the existing landfill will need to be updated to include the landfill
expansion area. A detailed erosion control plan will be included within the updated SWPPP.
2.8 FLOOR PLANS
Building sizes and sections for the Gem Ash, Recycling building and maintenance building to be relocated
are shown on the attached Plan sheets. The new office building is proposed to be 10,000 square feet.
The buildings have not been designed and finalized at this early stage in the project but will be completed
and submitted to the City as part of the building permit approval process.

Project Number: 227702665 2-6
2.9 LOT LIGHTING
Lighting will also be provided along the entrance/exit driveway areas. It is important to note that all
outdoor lighting will be LED low profile. The outdoor lighting will be aimed downward and have bulb caps
or shields to minimize any light pollution. All non-essential lighting will be turned off after business hours.
2.10 SIGNAGE
The appropriate signage for the landfill expansion will be placed at the new site entrance/exit. The
proposed signage will be provided to the City for approval prior to installation.
SKB ENVIRONMENTAL PROPOSED LANDFILL EXPANSION
Proposed Facility Operations
Project Number: 227702665 3-1
PROPOSED FACILITY OPERATIONS
3.1 GENERAL FACILITY OPERATIONS
There are multiple disposal areas at the Rosemount Industrial Waste Landfill that receive separate waste
streams. The disposal areas include demolition debris disposal, industrial waste disposal, and municipal
solid waste combustor ash disposal. The landfill does not include municipal solid waste (MSW) disposal
areas. Each solid waste disposal area has an allowable list of acceptable waste types that can be placed
within the cells, specific to the demolition, industrial, and municipal solid waste combustor ash disposal.
Acceptable wastes are defined and managed under the terms of the solid waste plans that are attached
to the permit SW-383. Unacceptable wastes are rejected by the facility and waste haulers are required to
take them offsite to an acceptable disposal facility.
Waste for disposal and/or recycling is transported to the facility via trucks which enter the facility at the
main site access from Courthouse Boulevard (State Highway 55), where they access one of the scales at
the facility before proceeding to the appropriate waste disposal area. Historically, the landfill receives
between 100 and 1,000 trucks per day delivering waste to the facility. SKB is not proposing to change the
solid waste transport methods or daily volumes received at the facility from the existing conditions under
which the landfill has been operating but is proposing to create a new site entrance/exit to serve the
existing landfill as well as proposed expansion areas. The existing site entrance/exit to the SKB facility
located on MN Hwy 55 will be closed. The new site entrance/exit is shown on the attached Plan Drawings
and is discussed in more detail in Section 3.4 of this Narrative Report.
There are currently seven disposal cells that comprise the SKB Rosemount Industrial Waste Landfill. The
surface area of the disposal cells are as follows:
•Cell 1 (Industrial Waste) covers 5.1 acres and is closed
•Cell 2 (Industrial Waste) covers 17.1 acres
•Cell 3 (Industrial Waste) covers 39.4 acres
•Cell 3M area included within industrial waste areas and is closed
•Cell 4 (Combustor Ash) covers 12.5 acres
•Cell 5 (Demolition Waste) covers 41.2 acres
•Cell 6 (Permitted but not constructed Industrial Waste) covers 51.8 acres
Each disposal area is permitted for a total disposal capacity based on waste type. Cell 1 has been closed
including the final cover and will not receive additional waste. Additionally, the Cell 3M disposal area is
also closed. Cell 6 has been permitted and construction of Cell 6 was completed in 2021. SKB submitted
a minor modification application to the current MPCA permit to alter the proposed base grades in Cell 6 to
provide and maintain for a 5-foot separation from the subgrade to the groundwater table. This redesign of
the base grades resulted in a loss of approximately 464,000 cubic yards of currently permitted disposal
capacity in Cell 6. SKB will also be submitting to the MPCA as part of the eastern landfill expansion a
permit application which will detail a redesign of the final cover grades. This final cover grade redesign
will not increase the height of the landfill but will recoup approximately 200,000 CY of the 464,000 CY of
disposal capacity lost due to raising the currently permitted base grades in Cell 6. The redesign of the
SKB ENVIRONMENTAL PROPOSED LANDFILL EXPANSION
Proposed Facility Operations
Project Number: 227702665 3-2
Cell 6 base grades and the redesign of the final cover grades over the existing landfill are shown and
detailed on the Plan Drawings provided with the IUP memorandum.
3.2 STORMWATER MANAGEMENT
The surface water management system has been designed to manage the 100-year, MSE-3 storm event
of 7.42 inches for the full landfill property boundary. The system consists of swales, downslope structures,
perimeter ditches, catch basins and culverts draining to one of 12 stormwater features.
There are two discharge points from the site. Off-site drainage includes 97 acres and results in 151.1 cfs
runoff during the 100-Yr storm event. As previously approved in the 2013 Master Plan, the drainage from
Basin 6A/B is limited to the rate from off site.
3.2.1 Subwatersheds & Peak Runoff
As part of the two horizontal landfill expansions, stormwater management will be similar to current plan for
the existing footprint and for the proposed northwest expansion. Stormwater from the north side and west
side of the landfill will make its away around the west and south sides of the landfill via stormwater basins
interconnected via culverts, weirs, and perimeter ditches to the southside of the landfill where it will
discharge out a structure to the right-of-way of 140th St E. For the new eastern expansion and the
southside of the existing landfill footprint, the water will be directed to one of five new interconnected
stormwater basins on the eastern end with the final stormwater basin (8b) located on the east side of the
access road. Basin 8b does not discharge during the 100-yr rainfall event.
HydroCAD-Stormwater Modeling Program using the SCS Curve Number method was used to calculate
run-off hydrographs for the ultimate proposed landfill configuration. To determine surface water run-off for
this analysis, the landfill was divided into subwatersheds depending on the contributing drainage areas.
Peak runoff was estimated using a runoff curve number (CN) of 63 (contoured small grain, poor
vegetation, HSG A) for the contributing landfill and perimeter pervious surface areas and a CN of 98 for
gravel surfaces, paved roads, buildings and water surfaces.
Time of concentration was computed using hydraulic distance and flow velocity according to NRCS
Hydrology Guide for Minnesota. Calculated time of concentration values were entered into the HydroCAD
model as direct entry. A minimum time of concentration of 7 minutes was utilized.
These runoff calculations are used as inputs in the following calculations, sizing the various components
of the surface water management system discussed below. Runoff calculations and a map showing the
runoff subwatersheds are also provided.
3.2.2 Drainage Swales
Swales are placed on the 4H:1V slopes and are sloped at a minimum of 1 percent and a maximum of 2
percent to downslope structures. These are placed in order to intercept and direct flow, as well as
minimize erosion. In order to minimize maintenance issues, a minimum 2 percent slope is preferred for
SKB ENVIRONMENTAL PROPOSED LANDFILL EXPANSION
Proposed Facility Operations
Project Number: 227702665 3-3
drainage swale construction with 1 percent being placed near the base of the slope. The following
parameters were used for the drainage swales design:
•Bed Slope:1%
•Inside Sideslope:4H:1V
•Outside Sideslope:2H:1V
•Mannings n:0.035
•Flow Rate Q100:Varies from 7.20 cfs to 45.62 cfs
The peak flow depth for a 100-year event will range from 0.98 to 1.95 feet, which will not exceed the
depth of the swale, and the velocities will range from 2.5 feet/second to 4.0 feet/second.
•Bed Slope:2%
•Inside Sideslope:4H:1V
•Outside Sideslope:2H:1V
•Mannings n:0.035
•Flow Rate Q100:Varies from 2.96 cfs to 113.76 cfs
The peak flow depth for a 100-year event will range from 0.62 to 2.41 feet, which will not exceed the
depth of the swale, and the velocities will range from 2.6 feet/second to 6.5 feet/second.
Drainage swales will be lined with erosion control matting and/or riprap, if required, where indicated on
the drawings. Drainage swales with velocities greater than 4 feet/second will be lined with Category 4
Erosion Control Blanket and drainage swales with velocities less than 4 feet/second will be lined with a
Category 2 Erosion Control Blanket.
3.2.3 Downslope Structures
Each swale discharges into a downslope structure. Turf reinforcement mat or concrete mat systems will
be used where the downslope structure discharges to the stormwater basins.
Each segment of each downslope structures is designed to handle the peak flow for each subwatershed
and summarized below:
Bed Slope: 25% Bottom Width: 5 feet
Left & Right Sideslope: 3H:1V Mannings n: 0.035
Based on the expected velocities and shear stress, each downslope structure will be lined with rock
gabions mats, articulated concrete, rip rap or erosion stabilization mat capable of sustaining the design
requirements presented above. Flow depth does not exceed the downslope channel maximum depth of
two feet.
SKB ENVIRONMENTAL PROPOSED LANDFILL EXPANSION
Proposed Facility Operations
Project Number: 227702665 3-4
3.2.4 Stormwater Basins
Surface water discharges are directed through eight downslope structures and eventually travel on to one
of 12 stormwater basins, around the perimeter of the landfill footprint. Basins 1 through 5 and basins 11
and 12 work in a series to provide sedimentation settlement, treatment, and peak flow attenuation of
runoff. Pond 5 discharges via weir into a perimeter ditch that discharges into Basin 6A. Then Basin 6A in
conjunction with Basin 6B ultimately would discharge off-site into the right-of-way of 140th Ln E. Basins 11
and 12 manage stormwater from the proposed building site. Then ponds 7 through 10 also work similar
fashion to basins 1 through 5 and 11 and 12 to manage runoff from the southside and proposed eastern
expansion. Basins 7 through 10 ultimately discharge off-site through Basin 8b. The network of basins
have been sized per City of Rosemount requirements.
3.2.5 Variance request
A variance on the 4:1 side slope for Basins 3&4, 5, 6a and 6b is requested for the following reasons.
The off-site drainage that is directed through the stormwater features on the west need to be designed to
handle the off-site drainage, not just drainage from the landfill. See Note 1.
Concept design for Basins was approved in the 2013 Master Plan with 3:1 side slopes
Site constraints (RR tracks on west and expanded ROW for 140th Ln) eliminate opportunity to increase
storage in basins to handle off-site drainage
Note 1: Basin 3&4 do not accept drainage from off-site. However, Basin 5 needed to expand further north
than previously design to accept off-site drainage and therefore reduce storage in 3&4.
Infiltrometer testing was completed onsite to estimate infiltration rates within the infiltration bench area.
Testing was completed in site soils similar to those anticipated to be encountered during pond/bench
excavation (determined based on boring log data from the site). Testing was completed in April 2019
using a double-ring infiltrometer. Results indicated an average infiltration rate of approximately 4.8 inches
per hour. The City allows a maximum design infiltration rate of 3.0 inches per hour. Based on the on-site
testing, the allowable maximum rate was used for design.
Per City comment, the infiltration area is required to be greater than or equal to the area as calculated
below:
Basin DA (acres) ÷ Infiltration Rate (in/hr) * 0.0416 (conv. Factor) = Required Infiltration Area (acres)
Using the design infiltration rate of 3.0 inches per hour, the required infiltration area for the entire site
development drainage area of 345.5 acres is greater than or equal to 4.79 acres. An infiltration area of
approximately 16.14 acres has been provided. All ponds infiltrate within 48 hours.
Below is a table of the City of Rosemount requirements and the design parameters of the proposed
stormwater basins:
SKB ENVIRONMENTAL PROPOSED LANDFILL EXPANSION
Proposed Facility Operations
Project Number: 227702665 3-5
Table 1: Stormwater Basins Design Summary
Requirement Proposed Stormwater Ponds
(Current Design Iteration)
No discharge or infiltration assumed for purposes of
establishing the 100-year, 24-hour storm event HWL.
Storage of the runoff from the 100-year 24-hour storm
event is required on-site.
Does not discharge during 100-year event.
For events with longer duration, a maximum peak
stormwater discharge rate will be limited to 0.05
cfs/acre.
The 200-year, 24-hour storm event was modeled and
resulted in discharge of 13.81 cfs, the discharge
elevation is approximately 345 acres in area; therefore,
the discharge requirement has been met (0.04 cfs/acre
discharge) for stormwater Basin #6A and Basin 8.
Development will be required to provide 1/12 of an
acre-foot/acre/day of infiltration for the entire site’s
acreage. Maximum of 3.0 in/hour. The development
drainage area is 345.5 acres; 1/12 ac-feet/acre *
345.5 acres = 28.8 ac-feet/day required.
Using the allowable maximum rate of 3.0 in/hr, based
on the infiltration area, 101.63 ac-ft per day of
infiltration is provided (infiltration area = 16.14 acres;
16.14 acres * 3.0
inches/hour * 24 hour/day ÷ 12 inches/foot = 96.84 ac-
feet/day).
Permanent pool (“dead storage”) volume greater or
equal to the runoff from a 2.5- inch storm event over
the contributing area.
2.5-inch run-off over the entire drainage area is 10.65
ac-feet. The “dead storage” provided is approximately
12.74 ac-feet, indicating conformance with this
requirement.
Permanent pool average depth > 4 feet with maximum
of < 10 feet.
The permanent pool depth for all the basins fall within
that range.
Required Infiltration area ≥ 4.62 acres; drawdown time
< 48 hours
The infiltration area provided is approximately 16.2
acres. The depth over the infiltration area is a
maximum of 10’ feet; using an infiltration rate of 3.0
inches/hr, the drawdown time is less than 48 hours.
3.3 HOURS OF OPERATION AND SERVICE
Hours of operation of the Facility are authorized as 6:00 a.m. through 8:00 p.m. Monday through Saturday
under the terms of the existing IUP. The hours of operation for the Facility can be amended by the City
SKB ENVIRONMENTAL PROPOSED LANDFILL EXPANSION
Proposed Facility Operations
Project Number: 227702665 3-6
Council to accommodate special projects at the landfill. SKB is not currently proposing changes to the
hours of operation listed in the IUP.
3.4 TRAFFIC, NOISE, DUST AND ODOR
It is important to note that a noise analysis, detailed traffic analysis, and dust and odor evaluation were
completed as part of the EAW process for this project. There are no negative impacts anticipated with the
landfill expansion related to traffic, noise, dust, or odor. Please refer to the EAW for more detailed
information. There have been changes to the proposed City Road since the submittal of the EAW and an
updated traffic section is provided below.
SKB Environmental, Inc. (SKB) is proposing to expand the SKB Rosemount Industrial Waste Disposal
Facility located at 13425 Courthouse Boulevard (TH 55). There are currently multiple disposal areas at
the Facility that receive different waste streams, which include demolition debris, industrial waste, and
municipal solid waste combustor ash disposal. The expansion area would receive only industrial waste
and SKB is proposing to increase the industrial waste landfill capacity by expanding onto approximately
113 acres of adjacent land immediately east of the current landfill disposal area. This expansion will
provide approximately 20 years of industrial waste disposal operations beyond what is currently permitted
for the Facility.
As the expansion moves east within the site, a new access will be provided on a new north/south public
street located west of CSAH 42. The existing access to TH 55 will be closed when the new access is
constructed. These changes will help fulfill safety improvements on TH 55 that are needed to
accommodate existing and future traffic volumes. SKB has worked closely with the City of Rosemount
and the Minnesota Department of Transportation (MnDOT) to develop and implement roadway safety
improvements for this area. The proposed new north/south roadway to be constructed off of Ehlers Park
will assist in these improvements by removing existing private access points from TH 55.
The proposed project will not increase the number of trips generated by the site. The existing trip
generation is expected to continue in the future through the life of the facility. Existing trip generation for
the site was determined through driveway counts completed on September 24 and 25, 2019. The
resultant trip generation totals are shown in Table 1.

There are approximately 30 parking spaces currently on site. The number of parking spaces in the future
is expected to be approximately 100 to serve the new office location.
This analysis examined weekday a.m. and p.m. peak hour traffic impacts of the proposed project the
following intersections:
•TH 55/SKB access (existing)
•TH 55/CSAH 42
•CSAH 42/142nd Street
•142nd Street/future north-south street
To adequately address the impacts of the proposed project, forecasts and analyses were completed for
the year 2040. Specifically, weekday a.m. and p.m. peak hour traffic forecasts were completed for the
following scenarios:
•2022 Existing. Existing volumes were determined through traffic counts at the subject
intersections. The existing volume information includes trips generated by the existing facility.
•2040-Build. Existing volumes at the subject intersections were increased by 1.3 percent per year
to determine 2040 Build volumes. The 1.3 percent per year growth rate was calculated based on
recent growth experienced near the site.
The 2040 forecasts assume a new access will be provided on a new north/south public street
located west of CSAH 42. The existing access to TH 55 will be closed when the new access is
constructed. The new north/south roadway will extend north from 142nd Street and will end in a
cul-du-sac south of TH 55.
•Traffic volumes were established for the forecasting scenarios described during the weekday a.m.
and p.m. peak hours. The resultant traffic volumes are presented in Figure 1.
Traffic analyses were completed for the subject intersections for all scenarios during the weekday a.m.
and p.m. peak hours using Synchro software. Initial analysis was completed using existing geometrics
and intersection control.
Capacity analysis results are presented in terms of level of service (LOS), which is defined in terms of
traffic delay at the intersection. LOS ranges from A to F. LOS A represents the best intersection
operation, with little delay for each vehicle using the intersection. LOS F represents the worst intersection
operation with excessive delay.
The LOS results for the study intersections are discussed below.
TH 55/SKB access (driveway stop control) - During the a.m. peak hour under existing conditions, all
movements operate at LOS E or better and the overall intersection operates at LOS A. Under the 2040
scenario, the SKB access (south leg) is removed from the intersection. All remaining movements operate
at LOS D or better and the overall intersection operates at LOS A.
During the p.m. peak hour under existing conditions, all movements operate at LOS E or better and the
overall intersection operates at LOS A. Under the 2040 scenario, the SKB access (south leg) is removed

from the intersection. All remaining movements operate at LOS C or better and the overall intersection
operates at LOS A.
TH 55/CSAH 42 (minor street stop control) - During the a.m. peak hour under existing conditions, the
northbound left turn operates at LOS F while all other movements operate at LOS B or better. The overall
intersection operates at LOS A. Under the 2040 scenario, the northbound left turn operates at LOS F
while all other movement operate at LOS B or better. The overall intersection operates at LOS A.
During the p.m. peak hour under existing conditions, the northbound left turn operates at LOS F while all
other movements operate at LOS E or better. The overall intersection operates at LOS A. Under the 2040
scenario, the northbound left turn and northbound right turn operate at LOS F while all other movement
operate at LOS C or better. The overall intersection operates at LOS D.
CSAH 42/142nd Street (minor street stop control) - During the a.m. peak hour under existing conditions, all
movements operate at LOS A and the overall intersection operates at LOS A. Under the 2040 scenario,
all movements operate at LOS B or better and the overall intersection operates at LOS A.
During the p.m. peak hour under existing conditions, all movements operate at LOS B or better and the
overall intersection operates at LOS A. Under the 2040 scenario, all movements operate at LOS B or
better and the overall intersection operates at LOS A.
142nd Street/new north-south street (minor street stop control) - During the a.m. peak hour under existing
conditions, all movements operate at LOS A and the overall intersection operates at LOS A. Under the
2040 scenario, all movements operate at LOS A and the overall intersection operates at LOS A.
During the p.m. peak hour under existing conditions, all movements operate at LOS A and the overall
intersection operates at LOS A. Under the 2040 scenario, all movements operate at LOS A and the
overall intersection operates at LOS A.
The analysis shows that due to the amount of background growth by 2040, the TH 55/CSAH 42
intersection is expected to operate at poor levels of service with the existing intersection geometrics and
control. All other intersections are expected to operate at acceptable levels of service. The TH 55/CSAH
42 intersection would require dual westbound left turn lanes and traffic signal control. With these
improvement in place, all movements operate at LOS E or better and the overall intersection operates at
LOS D or better.
The traffic forecasts and analyses indicate the proposed project alone would not require specific
improvement to accommodate the expected traffic volumes. As indicated, the expected increase in
background traffic and safety of traffic entering and exiting the site will require the following mitigation
improvements:
Existing Conditions
•All intersections operate at acceptable levels of service; therefore, no mitigation is recommended.
•Consider constructing an eastbound acceleration lane at the existing SKB access on TH 55.

2040 Condition
•The TH 55/CSAH 42 intersection is expected to operate at poor levels of service with the existing
intersection geometrics and control. All other intersections are expected to operate at acceptable
levels of service. The TH 55/CSAH 42 intersection would require dual westbound left turn lanes
and traffic signal control.
3.5 CULTURAL RESOURCES SURVEY
To supplement the EAW completed for this project a Cultural Resources Survey was completed at the
site. No cultural resources were found and the findings are provided in a report in Appendix G.
3.6 REGIONAL CONSIDERATIONS
SKB is committed to working with the City and Dakota County to ensure that there is a path for a
Regional trail. The trail can be accommodated with the proposed development project

Memo
To: City of Rosemount From: Tom Shustarich, P.E.
File: 2277022665 Date: March 24, 2022
Reference: Interim Use Permit Reapplication for the SKB Rosemount Industrial Waste Landfill
Purpose
SKB Environmental, Inc. (SKB) respectfully submits to the City of Rosemount (City) this Project Description
as part of a renewal application for an Interim Use Permit (IUP) for the SKB Rosemount Industrial Waste
Landfill. This IUP renewal application is being submitted under one cover along with a Comprehensive Guide
Plan Amendment Application, a Rezoning Application, and Preliminary Plat Application. The Applications are
being submitted because SKB is proposing to increase the industrial waste and C&D landfill capacity by
expanding onto approximately 163 acres of adjacent land immediately east of the current landfill disposal area.
The landfill expansion will be approximately 119.1 acres in size, while the remaining 43.9 acres is being
designated for business park development. The existing landfill is located within an area of the City that is
classified as a “Waste Management Area” on the City’s zoning map. The City’s zoning code for the Waste
Management District state that this district is intended to accommodate waste management, disposal, and
recycling operations and that uses within this district shall be permitted by an Interim Use Permit. The
approximately 119.1acres of the 163 acres of adjacent land will also need to be rezoned to reflect WM “Waste
Management Area”. On the 49.9 acres east of the new proposed city road, a future business park will be
developed according to the City’s Zoning and Comprehensive Plan. The landfill expansion will require
relocation of the existing landfill infrastructure such as office, scale, scalehouse, and maintenance building. A
new site entrance/exit off Ehler’s Path in conjunction with a new public street, to be designed and constructed
by the City of Rosemount (City), is proposed. SKB will also relocate the facility sustainability campus which
will include buildings to serve recycling activities at the landfill.
Background
The landfill is located at 13425 Courthouse Boulevard within sections 19, 20, and 29, Township 115N, Range
18W, Dakota County, Minnesota. The total property for the landfill facility is approximately 237 acres (see
Figures 1 and 2). The landfill has been in operation since 1992 and was purchased in 2000 by SKB who has
been operating the facility since that time. An initial IUP was issued by the City for the landfill when the facility
opened in 1992, and SKB assumed the obligations of the IUP at the time it began operating the facility in
2000. The landfill has an existing IUP from the City of Rosemount that was renewed by the City on November
5th, 2018 (see Attachment 1). The landfill operates under Minnesota Pollution Control Agency (MPCA) solid
waste permit number SW-383 (available upon request). The MPCA reissued SW-383 for the landfill in 2014
with a ten-year term until 2024. The landfill also operates under a solid waste facility license (see Attachment
2) and a Gem-Ash processing license (see Attachment 3), both issued by Dakota County and valid through
2021.
There are currently multiple disposal areas at the Facility that receive different waste streams, which include
demolition debris, industrial waste, and municipal solid waste combustor ash disposal. The expansion areas
would receive only industrial waste and construction and demolition debris (C&D). SKB is proposing to
increase the industrial waste and C&D landfill capacity by expanding onto adjacent land immediately east of
the current landfill disposal area as well as in the area where the current office and scale are located. The two
expansion areas will together provide approximately 21,200,000 cubic yards of disposal capacity. Preliminary
detailed development plans are provided as Attachment 4 to this memorandum. The Plan Drawings

(Attachment 4) detail, for both the eastern and northwestern expansion areas, proposed base grades,
leachate piping and collection, final cover grades, stormwater management, and design details.
As stated up front, this submittal serves as the reapplication for the existing IUP for the landfill to allow for the
continued solid waste disposal and recycling operations of the Rosemount Industrial Waste Landfill as well as
an expansion of the landfill on 119.1 acres to the east. As directed by the City and through written and verbal
correspondence, this memo provides summary updates of the ongoing activities at the Rosemount Industrial
Landfill including facility operations, waste disposal areas, proposed permit modifications, leachate collection,
and landfill gas monitoring. SKB will continue to operate the Rosemount Industrial Waste Landfill under the
terms of MPCA solid waste permit SW-383, the IUP permit from the City, and the additional requirements
from the City and Dakota County. The MPCA permit and County license will also be modified to reflect the
proposed landfill expansion. An Environmental Assessment Worksheet (EAW) was prepared for this project.
Landfill Operations
Hours of operation of the facility are authorized as 6:00 AM through 8:00 PM, Monday through Saturday
under terms of the existing IUP. The hours of operation for the facility can be amended by the City to
accommodate special projects at the landfill. SKB is not currently proposing changes to the hours of
operations listed in the IUP.
Facility Summary
There are multiple disposal areas at the Rosemount Industrial Waste Landfill that receive separate waste
streams. The disposal areas include demolition debris disposal, industrial waste disposal, and municipal solid
waste combustor ash disposal. The landfill facility also includes a solid waste recycling area. Additionally, the
facility is permitted to include a solid waste transfer station and a solid waste composting facility. The landfill
does not include municipal solid waste (MSW) disposal areas. The solid waste disposal cells can be seen on
the Plan Drawings (see Attachment 4). Each solid waste disposal area has an allowable list of acceptable
waste types that can be placed within the cells, specific to the demolition, industrial, and municipal solid waste
combustor ash disposal. Acceptable wastes are defined and managed under the terms of the solid waste
plans that are attached to the permit SW-383. Unacceptable wastes are rejected by the facility and waste
haulers are required to take them offsite to an acceptable disposal facility.
Solid waste is transported to the facility via trucks which enter the facility at the main site access from
Courthouse Boulevard (State Highway 55), where they access one of the scales at the facility before
proceeding to the appropriate waste disposal area (see Attachment 4). Historically, the landfill receives
between 100 and 1,000 trucks per day delivering waste to the facility. SKB is proposing to change the site
access point to the landfill. As the expansion moves east within the site, a new access will be provided on a
new north/south public street located west of CSAH 42. This new road will provide a new entrance to the
landfill expansion area as well as an entrance to the future business park. The existing access to TH 55 will
be closed when the new access is constructed. The new proposed road will be designed by the City to
accommodate traffic volumes from both the landfill and the future business park. These proposed traffic
improvements associated with the landfill and business park development will help fulfill safety improvements
on TH 55 that are needed to accommodate existing and future traffic volumes.

The IUP identifies terms and conditions for construction and operations Rosemount Industrial Waste Landfill.
SKB will continue to operate the landfill following the requirements of the IUP including areas related to:
Landfill Design and Specifications; Quality Control and Assurance; Construction Permits; Construction
Certification; Soil Protective Cover; Operation and Maintenance; and Waste Acceptance.
Waste Disposal Areas
There are currently seven permitted disposal cells that comprise the Rosemount Industrial Waste Landfill. The
surface area and the waste disposal volume capacity of the disposal cells are as follows:
•Cell 1 (Industrial Waste) covers 5.1 acres with a capacity of 341,454 yrds3 (closed)
•Cell 2 (Industrial Waste) covers 17.1 acres with a capacity of 1,458,507 yrds3
•Cell 3 (Industrial Waste) covers 39.4 acres with a capacity of 10,592,188 yrds3
•Cell 3M has a capacity of 158,300 yrds3 (closed)
•Cell 4 (Combustor Ash) covers 12.5 acres and 2,648,950 yrds3
•Cell 5 (Demolition Waste) covers 41.2 acres with a capacity of 7,490,591 yrds3
•Cell 6 (Industrial Waste) covers 51.8 acres with a capacity of 12,659,927 yrds3
Each disposal area is permitted for a total disposal capacity based on waste type. Cell 1 has been closed
including the final cover and will not receive additional waste. Additionally, the Cell 3M disposal area is also
closed. It should be noted that construction of Cell 6 and the first cell were completed in 2021.
Based on the 2021 Annual Report for the landfill submitted to the MPCA the waste disposal areas are
summarized in Table 1. The disposal volumes in Table 1 reflect the remaining waste disposal capacities
based on the current version of SW-383 issued in 2014 for the landfill. Based on the recent annual fill
volumes for each disposal area and the remaining permitted capacities for each area, SKB estimates that the
remaining years of operations for the waste disposal areas are as follows:
•Demolition: 1.0 Years (averaging 500,000 yards per year)
•Industrial: 9.9 Years (averaging 1,350,000 yards per year)
•MSW Combustor Ash: 20.0 Years (averaging 64,700 yards per year)

demolition waste disposal volume based on the requested solid waste permit described below.
Annual surveys of the disposal capacity consumed and the disposal capacity remaining are conducted each
year in approximately November as part of the annual reporting required under solid waste permit SW-383.
These annual surveys are used to update the remaining operational life of the landfill disposal areas.
Similar, to the existing landfill operations and as required by MPCA rules, the proposed eastern industrial
waste landfill expansion will be developed in phases or cells. As shown on the Preliminary Design Plan
Sheets (Attachment 4), the proposed eastern expansion will be identified as Phase 7 and be developed with
three (3) cells. Due to the size of the northwestern expansion, it will be developed in one phase and identified
as Phase 8. The Phase 7 cells and estimated waste capacity (including final cover) of each cell and Phase 8
is as follows:
Phase 7 - Eastern Expansion:
• Cell 7A - 5,800,000 Cubic Yards
• Cell 7B - 5,600,000 Cubic Yards
• Cell 7C - 5,900,000 Cubic Yards
Phase 8 - Northwestern Expansion:
•Cell 8 - 3,900,000 Cubic Yards
Proposed Permit Modification
In 2016, SKB submitted a modification application to the MPCA, Dakota County, and City of Rosemount to
allow for redesign of a “wedge” of airspace between the industrial and demolition disposal to create a new
industrial disposal cell. The modification requested the conversion of this wedge area from demolition
disposal capacity over to industrial disposal capacity. The modification application was approved and
increased the total disposal capacity of the industrial areas by 2,955,523 cubic yards, and a result in a
corresponding reduction in the demolition disposal capacity. Similar, to the 2016 process, SKB will be
submitting modification applications to the MPCA and Dakota County for the proposed eastern and northwest
expansion areas. The applications are in the process of being completed and will be submitted in 2022.

Cell Construction and Wetland Impacts
The July 2014 renewal of MPCA solid waste permit SW-383 included an approval for the construction of an
expanded Cell 6. Environmental review evaluating the potential impacts of the landfill expansion and
construction of Cell 6 was completed by the City who issued a negative declaration regarding the need for an
Environmental Impact Statement (EIS) in November 2013. The landfill expansion and construction of Cell 6
authorized impacts, including filling, of up to 9.19 acres of wetlands on the facility property. A wetland permit
and approved wetland replacement plan for the wetland impacts was issued to SKB in November 2013. The
replacement plan includes the purchasing of 18.28 acres of wetland credits from approved mitigation banks.
SKB is intending to begin construction in 2021 of the Cell 6 area that would result in the impacts to the
wetlands. SKB recently submitted a request for an extension of the wetland permit. A five-year extension to
the wetland permit, through September 3, 2026, was granted to SKB on September 3, 2021. The approved
mitigation plan still includes the purchased of approved wetland bank credits to provide compensation for
wetland impacts that would result from the construction of Cell 6. A Grading Plan Application was submitted to
the City of Rosemount on March 1, 2021 for the filling of the wetland area in Phase 6.
Recycling
There a several recycling activities that are conducted at the Rosemount Industrial Waste Landfill. One
recycling activity is the separation and recovery of ferrous and nonferrous metals from construction and
demolition waste as well as from the municipal solid waste combustor ash. An additional recycling activity at
the landfill includes the separation and recovery of clean wood and concrete from construction and demolition
waste. The process of recovering these recyclable materials from the construction and demolition waste takes
place within the disposal cell. SKB has also implemented a recycling operation that entails mining metals from
the municipal solid waste combustor ash cells to recover these metals for recycling. All of the metal materials
recovered from the mining of the ash material takes place within the disposal cell. This operation began in
2015. The existing solid waste permit SW-383 includes approvals for the landfill to conduct composting
activities as well as operate a solid waste transfer station.
As part of the proposed landfill expansion (Cells 7 & 8), SKB will also relocate the facility sustainability campus
which will include buildings to serve recycling activities at the landfill. SKB intends to continue the current
recycling activities at the landfill and explore opportunities for additional recycling efforts that are economically
feasible.
Liner System
SKB is proposing to construct the Phase 7 and 8 industrial waste landfill areas with a liner system consisting
of three barrier layers. The currently permitted liner profiles approved for use at the site consist of, from the top
to the bottom:
•One foot of sand protective layer
•Drainage geocomposite
•Primary liner, which consists of an 80-mil high density polyethylene (HDPE) geomembrane

Reference: Interim Use Permit Reapplication for the SKB Rosemount Industrial Waste Landfill
mj u:\227702665\2022 update city app\interim use permit reapp memo22020324.docx
•Drainage geocomposite
•60-mil HDPE secondary liner
•Geosynthetic clay liner (GCL)
•Subgrade surface
and
•One foot of sand protective layer
•Drainage geocomposite
•80-mil primary liner
•GCL
•60-mil HDPE secondary liner
•Subgrade surface
As lining technologies advance, SKB may substitute, with MPCA and Dakota County approval, an item in the
approved liner profile with an equivalent or superior alternative. Also, if the constructed liner profile
incorporates a drainage composite as part of the leachate collection system, SKB will place a minimum of a
one-foot protective soil layer over the liner system for additional protection.
Leachate Management
The Rosemount Industrial Waste Landfill includes a leachate collection and management system. Leachate is
wastewater that is generated at a landfill that has percolated through the solid waste and now has extracted,
dissolved, or suspended materials within it. Leachate at the landfill percolates down through the waste until it
reaches the liner, where it is then directed to sumps. The sumps flow to the header pipes of the leachate
collection system. The leachate flows through the pipes to a centralized leachate storage tank. The leachate
collected at the tank is transported via a direct gravity line to the Metropolitan Council Environmental Services
(MCES) Empire Wastewater Plant. Stormwater that comes in contact with the waste is treated as leachate,
while stormwater that falls outside the active waste disposal areas is directed into the stormwater
management system at the landfill. Leachate is collected separately from the demolition, industrial, and ash
disposal areas, however all leachate is directed to the central storage tank and from there sent to the MCES
Empire Plant.
The landfill operators work to keep the active face of the disposal area as small as possible to minimize the
amount of rainfall that comes into contact with the waste and becomes leachate. Monitoring and analytical
testing of the leachate is conducted as required under the terms of the solid waste permit SW-383. SKB will
continue operation of the leachate collection and management system for the landfill as well continue the
monitoring of leachate for the landfill as required under terms of the solid waste permit SW-383.
Groundwater Monitoring
There is a groundwater monitoring network in place at the Rosemount Industrial Waste Landfill. This
groundwater monitoring system will be expanded as part of future MPCA permitting activities to monitor the
eastern landfill expansion area.
The groundwater flow in the area of the landfill is to the northeast towards the Mississippi River. Currently,
there are 28 monitoring wells and five piezometers where groundwater is monitored around the landfill
including shallow aquifer and deep aquifer groundwater wells. There are also wells located both upgradient

mj u:\227702665\2022 update city app\interim use permit reapp memo22020324.docx
and downgradient of the waste disposal areas. The upgradient wells are used as a control to establish
background groundwater conditions that are not potentially influenced by the landfill. During groundwater
sampling events, a total of 90 different analytical parameters are tested from the groundwater samples
including nutrients, metals, and organic compounds. To date, none of the detected parameters in the
groundwater samples were above the MPCA defined intervention limits for groundwater concentrations. SKB
will continue groundwater monitoring for the landfill as required under terms of the solid waste permit SW-383.
Final Cover Design
The final cover is designed to prevent precipitation from entering the waste. The MPCA approved final
capping system from top down is as follows:
•6” topsoil and vegetative cover
•30” cover soil
•A geocomposite drainage net
•40 mil LLDPE geomembrane
•12” buffer soil or intermediate cover layer
As final cover technologies advance, SKB may substitute, with MPCA and Dakota County approval, an item in
the approved final cover profile with an equivalent or superior alternative.
Slopes on the final cover system will range from 2 percent on top to 25 percent on the side slopes. The
highest elevation of the eastern expansion area will be approximately 1060 ft. NGVD where it ties into the
highest elevation of the existing landfill. The proposed final contours were designed not to maximize capacity,
but rather improve the overall aesthetics of the landfill. Stormwater runoff from the landfill site will be
controlled on-site by strategic placement of drainage swales, erosion control mats, and riprap, concrete, or
gabion downslope structures. Runoff will be directed to a perimeter ditch system that takes surface water to
the sedimentation ponds located around the site.
Stormwater run-on into the industrial waste disposal area will be prevented by site grading. Run-off from off-
site and undeveloped areas will be collected in external perimeter channels and natural drainage pathways
and routed away from the site.
Water moving through the capping system’s drainage geocomposite which is not collected in a mid-slope
drainage swale, will be collected in a 4” diameter perforated drainage pipe located along the perimeter of the
final cover’s toe and discharged to the perimeter ditch through a 4” diameter discharge pipe. A 4” diameter
discharge pipe will be installed every 100 linear feet along the anchor trench.
SKB is committed to a more rigorous cell capping schedule, which will reduce the amount of leachate
generated at the site.
Landfill Gas Monitoring
As waste within a landfill decomposes it generates gas. The amount and types of gas generated at a landfill is
dependent on the specific waste types. There is a landfill gas monitoring network at the landfill that consists of
16 monitoring points. Four of the points are located within the waste disposal cells and the remaining points
are located along the perimeter of the landfill site. Landfill gas monitoring is conducted quarterly at the
Rosemount Industrial Waste Landfill. The landfill gas monitoring mainly focuses on methane, which is a gas
generated from the decomposition of landfill waste. Methane has been detected during the gas monitoring

events at one of the waste cells, Cell 1 which is an industrial waste cell. There have been no detections of
methane at the perimeter monitoring points outside of the waste cells. SKB will continue gas monitoring for
the landfill as required under terms of the solid waste permit SW-383.
Site Security and Reporting
SKB maintains security at the site to control unauthorized access and will provide security for the eastern
landfill expansion. SKB also keeps an operating record of Facility activities, including a log of waste disposal
volumes and the amount of leachate generated and transported for treatment and/or disposal.
Site Screening
SKB is proposing to construct a screening berm for the adjacent property owner on the north portion of the
site. The proposed screening berm location is shown on the IUP Plans in Attachment 4. The screening berm
will generally be 6 to 8 feet high with maximum 3 to 1 sideslopes and have a 6-foot wide top. As-built
drawings of the screening berm will be prepared upon completion of berm construction.
Post Closure
As described above, a series of monitoring wells have been placed around the disposal facility to monitor for
impacts to groundwater from landfill operations throughout the proposed site life and for 20 years after the site
is closed, which is consistent with Minnesota Rules 7035.2655.
The Facility would be inspected and monitored during operation and for at least 20 years following closure.
SKB will continue to provide financial assurance for closure, contingency action, and the long-term monitoring
and maintenance of the site.

Re: SKB Rosemount 2nd Addition
Preliminary Plat Review
Preliminary Site Construction Plan Review
WSB File No 0018532-000
SUBMITTAL:
A Preliminary Plat and Preliminary Site Construction Plan for SKB Rosemount 2nd Addition have
been submitted. The plat is located south of TH 55, north of Ehlers Path and west of CSAH 42.
The Second Addition is adjacent and east of SKB Rosemount, the solid waste facility. The
submittal was prepared by Stantec Consulting Services, Inc. of Golden Valley, MN for SKB
Environmental. Engineering review comments were generated from the following plat documents
dated 04-11-2022, consisting of:
▪ Existing Conditions
▪ Site Plan
▪ Grading Plan
▪ Utility Plan
▪ Landscape Plan
EXISTING CONDITIONS:
The parent parcels of SKB Environmental 2nd Addition consists of Outlot A, SKB Environmental,
Lot 1, Block 1 Pine Bend Development Corporation and a metes and bounds parcel. The lands
current use is Agricultural land and a forested area. SKB Environmental 2nd Addition is an
expansion to the east of the sold waste landfill. The platted area is 75.6 acres.
PRELIMINARY PLAT AND SITE PLAN
SKB Environmental 2nd Addition consists of one lot and one outlot. The platted lot
contains the landfill expansion and industrial buildings proposed for the processing of solid waste.
The outlot is for future development of a business park. The proposed plat includes the extension
of one public street between Ehlers Path and Trunk Highway 55. This city street will provide
direct access to the landfill and the processing buildings. The proposed plat also provides a 50-
foot wide ½ right of way for the north half of Ehlers Path.
The preliminary plans identify the construction of the southerly portion of the proposed city street
routing traffic to the site from TH 55 to CSAH 42 to 142nd Street/Ehlers Path to the new city street
and then into the site. The utilization of 142nd Street and Ehlers Path for access and egress will

destroy the existing pavement as the current pavement is not adequate to accommodate heavy
truck traffic. The proposed city street is shown to have right of way dedication from Ehlers Path
to TH 55 but only the southerly portion is identified to be constructed at this time. The northerly
right of way alignment has a sharp curve immediately south of its intersection with TH 55. The
minimum street centerline radius must be increased to 300 feet.
Access to the site extends from the proposed city street located along the easterly plat boundary.
Upon accessing the site there is a 1,600-foot driveway extending up to scales and the proposed
office building. From the scales the truck traffic would continue west approximately 800 feet to
access the landfill areas and proposed processing buildings. Egress from the site is identified to
continue west utilizing the existing driveway that extends from TH 55. Egress can also be
accomplished utilizing the same route as for accessing the area.
Four buildings are proposed on the site. An office building, maintenance building, gem ash
building and recycling building. The buildings are located on the north side of the plat adjacent to
TH 55. The private driveway provides access and egress to each of the buildings.
The existing buildings serving the existing landfill area will be removed.
Outlot A, SKB Environmental 2nd Addition is located on the east side of the proposed city street
and will be provided access and egress from the proposed street.
1. The development Fees are indicated below based on the 2022 Schedule of Rates and
Fees. Fees are due with the final plat and subdivision (development) agreement.
▪ Watermain Trunk Charge: $6,500/acre
▪ Storm Sewer Trunk Charge: $6,865/ net developable acre
2. The proposed future street extending from TH 55 must have a minimum 300-foot
centerline radius. Revise the street centerline or straighten the road.
3. The proposed access and egress from the site will utilize Ehlers Path betwee n the
proposed street and CSAH 42. Ehlers Path does not have pavement structure adequate
to support heavy truck traffic.
4. Remove the existing driveway approach and culvert from the TH 55 right-of-way for the
existing residential property where the recycling building is proposed.
5. Verify that the proposed driveway from the future City street will accommodate truck
turning radii.
6. The pavement extending around the buildings must be more than 20 feet from the
building for fire equipment access and operations.
7. The right-of-way width for the city street must be shown on the site plan. The minimum
width for a rural section street is 100-feet.
GRADING AND DRAINAGE
Development of the landfill creates a 160-foot-tall berm that parallels TH 55. Site grading and
drainage north of the berm splits at the proposed office building. East of the building runoff flows
to the east/southeast along the north side of the driveway. This drainage way collects runoff from
the proposed office building, parking lot and driveway and is routed through 4 ponding and
infiltration areas. Runoff from west of the office building flows to the west through a series of
ponds and infiltration areas to an existing infiltration basin. Drainage within the landfill area is
collected by an underground tile system and pumped to a wastewater treatment facility.
A 6-foot-tall berm is located between the drive isle and the private property to the north.
8. FES 108 to FES 109 does not have cover over the pipe.
9. Fes 106 to FES 105 does not have cover over the pipe.
10. There are several drainage arrows that conflict with each other.
11. Provide a plan and profile view of the city street between TH 55 and Ehlers Path.

12. The ponding area in the southeast corner of the plat will flood across Ehlers Path before
water elevations reach the culvert elevation of FES 103.
13. Outlet FES must have riprap erosion protection extended to the bottom of the p onding
basin.
SANITARY SEWER AND WATERMAIN
Sanitary sewer service for the site is provided utilizing an on-site septic tank and drain field
system. The system design will be reviewed by the building official at the time of building permit
application. City sanitary sewer is not extended to the site, ultimately public sanitary sewer would
extend from the north/northeast to the office building area. The landfill will slightly alter the Cities
Comprehensive Sanitary Sewer Plan in that a proposed trunk line will be moved to the east to
serve property east of SKB Environmental Second Addition.
Water service to SKB Environmental Second Addition will be provided by extending an existing
16-inch trunk watermain east along the north side of TH 55 to the proposed future street. The 16-
inch trunk watermain must then be extended south within the future city street to Ehlers Path.
Water service to the site is provide from a looped water line that extends between the 16-inch
trunk watermain.
14. The watermain extension along TH 55 and within the future City street is 16 inch.
15. Hydrant locations and spacing need to be modified so spacing does not exceed 400 feet.
STORM SEWER
Storm sewer design and layout will be reviewed with the surface water management plan
submitted for the site. The plan is currently under review.
SURFACE WATER MANAGEMENT
The surface water management plan for SKB Environmental Second Addition will be reviewed
under a separate cover. Comments included in the surface water management review shall be
incorporated in the project design.
LANDSCAPE PLAN
The Landscape plan was reviewed for conflicts with infrastructure. Tree plantings should allow
space for access and maintenance of proposed infrastructure.
General
Infrastructure design shall be completed in accordance with the City of Rosemount’s Engineering
Guidelines and Standards. Infrastructure construction shall be completed in accordance with the
latest edition of the City’s General Specifications and Standard Detail Plates for Street and Utility
Construction.

Re: SKB Proposed Landfill Expansion Plan Review
WSB Project No. 018532-000
I have reviewed the documents provided by SKB Environmental on 4-26-2022 for the proposed
landfill expansion at 13425 Courthouse Boulevard, Rosemount, Minnesota 55068. Documents
reviewed include:
• SKB Application for Proposed Landfill Expansion - Dated 4-11-2022
Applicant should provide responses to each comment. I offer the following comments below.
Grading, Drainage, and Erosion Control Comments:
1. General
a. Ponds shown on plans differ significantly from how the ponds are modeled in
HydroCAD, modeling must reflect what is shown in the plans. Differences
include, but are not limited to, Basin 8 stage storage starts 7’ below elevations
shown in the plans, Basin 9 outlet is modeled as a 48” grate but a FES is shown
in the plans, and Basin 10 is modeled with 4 24” outlet culverts but only a 30”
culvert is shown in the plans.
i. This includes naming conventions, basins 3, 4, and 5 have different
routing and grouping between the modeling and plans.
b. Applicant to provide approximate schedule or staging of stormwater facilities
construction during interim buildout conditions.
c. Applicant to provide updated drainage areas figure.
d. Applicant to provide operations and maintenance agreement for all stormwater
facilities that will be privately maintained.
2. Ponds and Wetlands
a. The number, NWL and 100-year HWL must be shown on the plans for all basins.
b. All basins with dead storage must be modeled with a starting water surface at the
NWL.
3. Emergency Overflow Routes:
a. Applicant must provide emergency overflow locations and elevations for all
stormwater basins onsite. Currently they are only shown for basins 1 and 11.
b. It is not permissible for Basin 8A’s emergency overflow route to pass over the
proposed road.
4. Retaining Walls:
a. Not applicable.

5. Erosion Control:
a. Applicant to provide updated SWPPP for landfill expansion.
6. Grading:
a. Proposed grading of 3:1 on basins 7, 11, and 12 exceeds maximum allowable of
4:1 basin slope.
i. Proposed 3:1 slope on basins 3&4, 5, and 6A/B is allowable considering
past concept approval.
b. The submitted HydroCAD modeling includes a depression that overflows to
Basin 10, this depression must be shown on the grading plans.
c. Applicant to ensure flared end structures tie into grading at the proper elevations.
Multiple FES elevations on plans differ from surface elevation by several feet.
Stormwater Management Plan:
1. General Storm Sewer Design
a. All basins that overflow off the site (Basin 6A/B and Basin 8A) must have an
outlet control structure with a weir wall and sluice gate.
b. MN Dam Safety laws do not apply as long as the berm is below 6 ft or holds back
less than 15 ac-ft of water. Basin 7 as proposed is not exempt as it reaches 27.1
ac-ft of water under the 100-year storm event. In addition, the 100-year HWL of
880.22 for Basin 7 is well above the 140th St. shoulder elevation of 860’ near the
basin. Grading of this basin must be revised to meet MN Dam Safety laws.
c. Applicant to specify the casting type of CBMH112.
d. The pipe between FES 113 and FES 114 is shown as 12”, minimum pipe
diameter is 15” per City engineering guidelines.
e. Sheet piling is required for flared end structures off storm sewer 24” and greater
per City engineering guidelines. The City can provide FES piling detail if needed.
2. Water Quantity
a. Applicant to include HydroCAD modeling results of the 2- and 10-year storm
event as well as the 100-year, 10-day snowmelt event.
3. Rate/Volume Control
a. Applicant to amend soils within infiltration basins to City rate if 3.0 in/hr.
4. Freeboard
a. No comments.
5. Water Quality
a. Dead storage for each basin must match or exceed the 2.5” runoff volume for the
drainage area tributary to the basin. While this is true for the site overall, basins
such as 2, 4, and 10 have less dead storage than runoff volume. This
requirement must be met for each basin individually according to NURP design
standards.
b. Runoff from impervious surfaces must be routed via storm sewer to basin dead
storage. Impervious surface runoff cannot flow over infiltration surface without
pretreatment.
6. Easements
a. No comments.
