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.
4
• 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.
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). Staff is recommending that
the City continue to review the permit every five years, which means that the City would need to review the
IUP in 2026 halfway through the MPCA permitting period. 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.
5
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
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.

SUMMARY
Landfill Configuration
The SKB landfill facility is currently divided into six (6) different cells that accept three (3) different types
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
Chemlite 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
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 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 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 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 in 2022 to improve safety along the Highway 55 corridor near the SKB site, and
the City will be able to coordinate the construction its street with the other safety improvements.
8
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 exiting 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
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 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
9
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
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 2021, 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 next 2 years 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).
10
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.
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 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.
11
Grading – 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
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 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
12
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 will eventually provide a connection between the developed and developing portions of
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.
Screening/Buffering - Adjacent Residential Lot
The owner of the residential lot directly north and adjacent to the landfill area has previous called the City
to express concern about noise and debris from the current operation. She has also been made aware of
the pending expansion of the landfill, and requested that the applicant provide a more robust screen and
berm between her property and the planned access road and buildings. In response, the applicant is
proposing to construct an eight-foot high berm along the southern property line of the residential lot, and
will provide a fairly robust planting plan for this area as well. The berm and landscaping screening are
primarily intended to minimize impacts from the access road while providing a physical and visual screen
from the landfill expansion area.
13
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 plating 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. Staff
is not clear exactly how this was calculated and will need to have further conversations with the applicant
to further clarify these numbers. 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 as noted above,
will offer screening for the residential property owner to the north of the site. Staff will review the
previous project files and will reach out to the applicant prior to the Planning Commission to determine a
recommended number of trees for the landscape and tree preservation plan.
Final Plat
SKB has submitted a preliminary plat request in conjunction the interim use permit application, and 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
environmental effects.
14
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 address 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 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. Klatt,
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. The landfill expansion will be approximately 113 acres in size, while the
remaining 50 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 113 acres of the 163 acres of adjacent land will also need to
be rezoned to reflect WM “Waste Management Area”. The 50 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.
An Environmental Assessment Worksheet (EAW) was 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).

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 113 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
19,500,000 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 50 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 Highway 55. 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.

1.3 CONSISTENCY WITH COMPREHENSIVE PLAN
The proposed landfill expansion is consistent with nearby existing industrial uses and is consistent with a
transition between planned use categories. The landfill and proposed business park meets 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
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 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 50 acres to the east of the 113- 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 2020 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 113- acre expansion area.
SKB ENVIRONMENTAL PROPOSED LANDFILL EXPANSION
General Project Description
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 113 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.
SKB ENVIRONMENTAL PROPOSED LANDFILL EXPANSION
General Project Description
2.2
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.
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 was 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 Preliminary Design Plan
Sheets (Attachment 1), 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 - 5,600,000 Cubic Yards
Cell 7B - 5,400,000 Cubic Yards
Cell 7C - 5,600,000 Cubic Yards
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:
SKB ENVIRONMENTAL PROPOSED LANDFILL EXPANSION
General Project Description
2.3
• 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 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 492 trees. The proposed landscaping plans
provides for 492 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 341
foundation plantings to meet the city requirements were planting space is available.
SKB is also proposing to construct a screening berm for the adjacent property owner on the North portion
of the site. The proposed screening berm location as shown on the preliminary site construction plans in
Appendix A and will generally be 6 to 8 feet high with maximum 3to 1 sideslopes and have a 6-foot wide
top. As-built drawings of the screening berm will be prepared upon completion of berm construction.

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.
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 Matthew Summers, 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
SKB ENVIRONMENTAL PROPOSED LANDFILL EXPANSION
General Project Description
2.5
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,
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 2-1 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.
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.

Proposed Facility Operations
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 was discussed in more detail in the traffic section of the project EAW.
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, but not yet constructed. It should be noted that construction of
Cell 6 is scheduled to begin in 2021. SKB has submitted a minor modification application to the current
SKB ENVIRONMENTAL PROPOSED LANDFILL EXPANSION
Proposed Facility Operations
3.2
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 will result 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 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, 24-hour storm event
of 7.42 inches. A narrative and all calculations and details for the proposed stormwater management
system in accordance with City requirements are provided in Appendix F.
To help clarify, a summary of basin order/flow is as follows:
• Basin 11 to Basin 12 to Basin 1 to Basin 2 to Basin 3 & 4 to Basin 5 to Basin 6A in Conjunction
with Basin 6B discharges off-site.
• Basin 10 to Basin 9 to Basin to Basin 8 and Basin 7 also goes to Basin 8 which could be the
ultimate discharge point off-site for that series of basins.
Many of the basins act as a combination of stormwater and infiltration basins. A summary of basin
function can be found in the table below:
Pond Infiltration Area Provided Dead Storage Area Provided
Basin #1 Yes Yes
Basin #2 Yes Yes
Basin #3&4 Yes Yes

Basin #9 Yes No
SKB ENVIRONMENTAL PROPOSED LANDFILL EXPANSION
Proposed Facility Operations
3.3
Pond Infiltration Area Provided Dead Storage Area Provided
Basin #10 No Yes
Basin #11 Yes Yes
Basin #12 Yes Yes
The volume for dead storage and infiltration area meets City requirements.
Run-off from the facility will be controlled in accordance with an NPDES General Stormwater
Management Permit for the site. As discussed previously, the driving surfaces on-site are proposed to be
mainly bituminous and the site will be graded for stormwater to drain to the proposed pond located on the
southern portion of the property and away from the building in all directions. Regular inspections will be
conducted to prevent stormwater run-off and/or run-on problems. If problems are found, they will be
immediately corrected, and action will be taken to prevent a future occurrence. Recycling processing and
maintenance operations will take place within the enclosed facilities.
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
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.
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

CC: Stacy Bodsberg, Planning & Personnel Secretary
Brian Erickson, Director of Public Works/City Engineer
From: Tim Hanson PE, WSB Engineering Consultant
Date: July 7, 2021
Re: SKB Environmental Site Improvements
Site Plan Review
Grading Plan Review
Utility Plan Review
WSB File Number 018532-000
SUBMITTAL:
SKB Environmental has submitted site plan and construction plans for expansion of their site to
the east included expanded landfill area, building relocation (construction), revised access
location and public street. The plans submitted were prepared by Stantec. The owner of the site
is SKB Environmental. Engineering review comments were generated from the Preliminary Site
Construction Plans, dated 05.27.2021 included in the submittal are the following:
▪ Existing Conditions
▪ Removals and Preconstruction Erosion Control Plans
▪ Overall Tree Preservation Plan
▪ Overall Site Plan
▪ Overall Grading Plan
▪ Utility Plan
▪ Details
▪ Overall Landscape Plan and Details
GENERAL COMMENTS – Site Expansion:
SKB Environmental is located adjacent to the south side of TH 55 between the railroad spur
crossing of TH 55 and 145th Street. The existing developed site consists of four unplatted parcels,
the landfill expansion area consists five unplatted parcels with a sixth parcel located east of the
improvements identified in the submittal.
1. The proposed expansion of SKB Environmental site to the east includes the
dedication of a public street extending north to south from TH 55 to Ehler’s Path.
The proposed street will require subdividing the existing parcels and platting the
public Right-of-Way.
2. One of the existing parcels is the platted lot of Lot 1, Block 1, Pine Bend
Development Co.1st Addition. This lot and an adjacent parcel will need to be
subdivided to create the proposed street alignment.

K:\018532-000\Admin\Docs\2021.07.07 - SKB Environmental Site Improvements.docx
3. The development Fees are indicated below based on the 2021 Schedule of Rates
and Fees. Review of the fees paid with the previous site expansions needs to be
completed to determine if City fees were previously paid. Outstanding fees will be
due with the final plat and subdivision (development) agreement.
▪ Sanitary Sewer Trunk Charge: Not Applicable
▪ Watermain Trunk Charge: $6,500/acre
▪ Storm Sewer Trunk Charge: $6,865/acre
4. There are 7 proposed storm water basins/infiltration basins which must be placed
within drainage and utility easements.
5. The unplatted parcels should be platted with appropriate Right-of-Way and
drainage and utility easements dedicated. 140th Street and Ehler’s Path are
identified as a minor collector street in the City which requires an 80 foot wide
Right-of-Way for rural section roads, (40 foot ½ Right-of-Way) and the proposed
local street which has a 66 foot wide Right-of-way.
PROPOSED BUILDING REMOVALS AND RELOCATIONS
SKB Environmental proposes to remove the existing buildings located on the western edge of the
existing site and relocate them adjacent to TH 55 along the northern portion of the site. The
existing office building, maintenance building, and ash recycling building are identified to be
removed. New and expanded office building, recycling building, gem ash building, and
maintenance building are proposed to be constructed midpoint of the sites length adjacent to
TH55. Access to the buildings will be from the proposed City street and the sites private
driveway. The only identified parking area is adjacent to the office building.
ACCESS AND EGRESS
Access and egress for the site is proposed to be relocated from its current location which is just
east of the northwest corner of the parcel and the railroad crossing, to extend from the proposed
local street at the east end of the proposed landfill area. The proposed local street extends south
from TH 55 1,900 feet to Ehler’s Path. The driveway into the site is identified to be located 1000
feet south of TH 55, which is good spacing from TH 55.
The driveway extends into the site roughly 1,800 feet before reaching the scales. The driveway is
identified to be 55 feet wide which provides additional width for queuing trucks waiting for the
scales. The proposed access layout should eliminate trucks from queuing along TH 55. After
passing through the scales the trucks would access the landfill area and depart heading west
utilizing the existing access and egress driveway on to TH 55. In this traffic pattern the driveway
would only be utilized for vehicles departing the site.
Access to the office and maintenance building would utilize the same traffic patten.
6. The site plan identifies paved lanes around the proposed buildings, however, the
lanes are adjacent to the building not providing space between the building and a
potential wall collapse during a fire. The Fire Marshal must comment on the
location and size of the fire lanes.
7. The new drive must be reviewed for appropriate turning radii to provide for fire
equipment accessibility. The minimum turn radius can be requested from the Fire
Marshal.

8. The site plan identifies curb along the access aisles of the car parking area and
the parking lot. All other access aisles utilize roadside swales to collect runoff.
9. The access extending from the proposed City Street identifies a 15 radius for the
driveway. The volume of truck traffic would warrant a larger radius at the
driveway entrance.
GRADING PLAN
Seven storm water management/infiltration basins are identified on the plan. These basins
collect runoff from the impervious surface areas. The landfill area is collected by a separate
storm water system and pumped to the Metropolitan Councils Wastewater Treatment Facility.
Runoff from the office building and parking lot flows to the east, southeast to an infiltration basin
in the southeast corner of the development. This ponding area overtops to the roadside swale of
Ehler’s Path.
Runoff from west of the office building also flows through a series of ponds, culverts and
infiltration areas to an infiltration basin just west of the maintenance building. This infiltration basin
overtops to the west into an existing infiltration basin.
10. The grading plan identifies the proposed landfill area and slopes of the landfill at
1:4, There are several locations adjacent to the storm water ponds and infiltration
ponds in which the proposed slopes are 1:3. Rosemount standards identify a 1:4
slope as the maximum slope.
SANITARY SEWER AND WATERMAIN
Sanitary sewer for SKB Environmental is a private system consisting of septic tanks and a
mound drain field. The preliminary plans identify the location of the drain field and alternate drain
field site, and the septic tank location.
Public sanitary sewer will have to be extended from the northeast, across TH 55 to serve the site.
There is no public sanitary sewer in this area.
11. The proposed septic system must be reviewed by the City Building Official.
Existing 12-inch watermain extends along the north side of TH 55 and terminates 1,200 feet west
of the northwest corner of the existing landfill. This watermain is identified to be extended as a
16-inch trunk watermain to serve the proposed site. The trunk watermain is terminated in the
utility plan at the office building location. The utility plan identifies a 6-inch watermain extending
from the trunk water main to serve the buildings and provide fire protection in the area. No other
water main improvements are identified.
12. Multiple hydrants are identified to extend from the 6-inch watermain. The 6 inch
watermain will have to be an eight inch main to provide adequate fire flow to the
hydrants.
13. The eight-inch watermain will have to be connected back to the 16-inch trunk
watermain providing a loop for the system
14. Show a service line and curb stop for a domestic service line into the office
building.
15. The 16-inch watermain must be extended the length of the site and then south
with in the proposed street.
16. Detail review of the watermain plans shall conform to City design guidelines and
standards.

17. The 6-inch watermain proposed with this project shall be privately maintained.
STORM SEWER
SKB Environmental identifies storm sewer culverts to convey runoff across paved areas to
surface water management ponding areas and infiltration basins.
18. Detail design review will be completed on the storm sewer culverts. the storm
sewer system must conform to the City’s Engineering Guidelines and Standards.
19. The storm sewer culverts must also be shown in profile view.
20. The downstream end of the culvert must have rip rap installed to the bottom of
the ponding basin.
SURFACE WATER MANAGEMENT
The site improvements must be reviewed for surface water management, erosion and sediment
control and for storm sewer pipe sizing. The stabilization plan identifies erosion and sediment
control infrastructure proposed for the grading of the site. All erosion and sediment control items
may be adjusted or modified during construction.
21. The Surface water management review comments are attached.

Re: SKB Proposed Landfill Expansion Plan Review
WSB Project No. 017611-000
I have reviewed the documents provided by SKB Environmental on 6.29.2021 for the proposed
landfill expansion at 13425 Courthouse Boulevard, Rosemount, Minnesota 55068. Documents
reviewed include:
• SKB Application for Proposed Landfill Expansion - Dated 6.1.2021
Applicant should provide responses to each comment. I offer the following comments below.
Grading, Drainage, and Erosion Control Comments:
1. General
a. Indicate Basin 6A-1 on Figure 1 of Appendix F.
2. Ponds and Wetlands
a. No comment.
3. Emergency Overflow Routes:
a. The emergency overflow location and elevation for Basin 12 should be noted on
the grading plans.
4. Retaining Walls:
a. Not applicable.
5. Erosion Control:
a. An updated SWPPP and erosion control plan is required for the next submittal.
6. Grading:
a. Proposed basin grading of 3:1 exceeds maximum allowable of 4:1 basin slopes.
Stormwater Management Plan:
1. General Storm Sewer Design
a. All proposed buildings and bituminous roadway need curb and gutter to direct
runoff through storm sewer to NURP pretreatment basins on site.
b. All basins that overflow off the site (Basin 6A/B and Basin 8) must have an outlet
control structure with a weir wall and sluice gate. See included recommended
designs.
c. 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 6A/B as proposed are exempt from additional

dam safety regulation. However, Basin 8 as proposed is not exempt as it reaches
16.4 ac-ft of water under the 100-year storm event. In addition, the 100-year
HWL of 874.99’ for Basin 8 is well above the 140th St. shoulder elevation of 870’
near the basin. Grading of this basin must be revised to meet MN Dam Safety
laws.
2. Water Quantity
a. Clarify “…peak flow attenuation of runoff for .” on page 103.
b. Include HydroCAD modeling results of the 2- and 10-year storm event runoff as
well as the 10-day snowmelt and 2.5” storm runoff in the next submittal.
c. Include 100-year basin volumes on plan sheets in the next submittal.
d. Indicate additional impervious surface area due to proposed buildings in the
narrative of Appendix F.
3. Rate/Volume Control
a. Infiltration cannot be included in HydroCAD modeling. For newly developing
areas, no discharge or infiltration can be assumed for the purposes of
establishing the 100-year HWL.
b. While the infiltration rate of 3.0 in/hr was used in drainage modeling, greater
infiltration rates will be considered by the City Engineer based on percolation
tests or other pertinent information conducted by a professional soil scientist or
Professional Engineer.
