RECOMMENDED ACTION: Motion to Approve the Renewal of the Dakota Aggregates
Large Scale Mineral Extraction Annual Operating Permit for 2014.
ISSUE
Dakota Aggregates has applied for the annual renewal of their large scale mineral extraction permit on the
UMore property. In 2013, the mining was limited to the area along County Road 46 and Station Trail.
For 2014, Dakota Aggregates is proposing to expand more into the area adjacent to County Road 46 and
Station Trail and also begin mining about 1/4 mile south of County Road 42.
NOVEMBER 26 PUBLIC HEARING
The Planning Commission conducted a Public Hearing for the Dakota Aggregates Large Scale Mineral
Extraction Permit on November 26, 2013. No resident spoke during the public hearing. Following the
public hearing, Commissioner Husain questioned where the haulback material would be deposited. Shawn
Dahl of Dakota Aggregates responded that Dakota Aggregates has no haulback material at this time, but if
haulback material became available, it would be deposited in the dry mining areas and would never be
deposited in the wet mining areas. Commissioner Weber inquired on the status and location of the
screening berms. Staff explained that the berms on the north side of County Road 46 for Dry/Wet
Mining Sub-phases 1A and 2A have been established and vegetated this fall and that the berm for the
future phase 3 has been started. Additionally, staff stated that the existing tree line about 1/4 mile of
County Road 42 will be the primary screening for the North Dry Mining phases and that staff will work
with Dakota Aggregates this summer to identify any gaps in the treeline that would need to be
supplemented by additional vegetation. The Planning Commission recommended approval of the mineral
extraction permit without any changes to the conditions on a 4 to 0 vote. Commissioner Kurle was absent
from the meeting.
BACKGROUND
Applicant: Dakota Aggregates
Property Owner: University of Minnesota (UMore)
Location: Northwest corner of County Road 46 and Station Trail;and '/4 mile
south of County Road 42
Mining area in acres: 113.48 acre total area;35.02 acres about 1/4 mile south of County
Road 42 (Dry Mining) and 78.46 acres at the northwest corner of
County Road 46 and Station Trail (Dry/Wet Mining).
Comp Plan& Zoning: Agricultural Research
Extraction progress: 4 Phases of 16 (approximately 1%complete).
Nature of request: Annual renewal.
Dakota Aggregates began working on the site this year. Through October 9,2013, Dakota Aggregates had
removed and paid aggregate taxes on 16,500 tons of sand. Dakota Aggregates has also processed and
placed 40,000 tons of Class 5 on the floor of the Aggregate Processing area. Dakota Aggregates has not
hauled back any material in 2013.
Dakota Aggregates was permitted for and mined in only Dry/Wet Mining Sub-phase 1A in 2013. For
2014,Dakota Aggregates is requesting an additional seven sub-phases: Dry/Wet Mining Sub-phases 1B,
2A and 2B;and North Dry Mining Sub-phases 1A, 1B,2C,and 2D. The Dry/Wet Mining Sub-phases are
located on the northwest corner of County Road 46 and Station Trail. The North Dry Mining Sub-phases
are located about 1/4 mile south of County Road 42. The Dry/Wet Mining area trucks will access County
Road 46 at Station Trail. The North Dry Mining area will access County Road 42 through a haul road
running west to east along the former rail line about a '/4 mile south of County Road 42, then north along
Akron Avenue to the intersection with County Road 42.
The Large Scale Mineral Extraction Ordinance allows for two separate mining areas of no more than 80
acres each. The four North Dry Mining sub-phases total 35.02 acres. The four Dry/Wet Mining sub-
phases total 78.46. All activity this year in the Dry/Wet Mining area is planned to occur outside and above
the groundwater. In the future, once the entire area of these four Dry/Wet Mining sub-phases are within
a couple feet of the groundwater,Dakota Aggregates will bring in a barge and dragline to begin mining
below the groundwater elevation. The rest of the Dry/Wet Mining phases will be mined with the barge
and dragline.
While there was very little mining this year,a lot of activity has occurred. The entire ancillary use facility
(AUF),located east of the Dry/Wet Mining area has been graded;the aggregate processing equipment has
been installed;the Station Trail entrance with the scale house and office has been constructed; the required
groundwater monitoring wells have been installed,reviewed,and approved by City staff;and berms
around the AUF and Dry/Wet Mining Sub-phases 1A and 2B have been constructed. Additionally, the
landscaping has been installed on the berms screening Dry/Wet Mining Sub-phases 1A and 2B. In the
spring of 2014,the Akron Avenue access to County Road 46 will be constructed and County Road 46 will
be striped for left and right turn lanes at both Station Trail and Akron Avenue.
The only complaints that the City has received regarding Dakota Aggregates has been the amount of time
that some berms took to be seeded after they were graded. Staff has worked with Dakota Aggregates to
ensure that the berms be seeded and vegetated within the time required by City and State regulations.
CONCLUSION & RECOMMENDATION
Staff recommends approval of the large scale mineral extraction permit for 2014.

jy/Wet Mining Sub-phase 1B,2A&2B
Activities related to Dry/Wet Mining sub-phases 1B through 2B will include relocation of surface
soils,berm construction,crushing,and mixing, screening, stockpiling, aggregate washing,loading,
hauling and conveying of aggregate materials to the Ancillary Use Facility(AUF). Once the
overburden material has been relocated, stockpiled or utilized for berm construction,mining
activities will be initiated by the use of loaders, screens,and conveyors and aggregate material will
be transferred to the AUF for material processing. Once the material is conveyed to the AUF,it
will be processed into varying construction grade aggregate products that will be hauled offsite at
either the Station Trail/CSAH#46 access or at the existing Akron Avenue/CSAH#46 access
location.
A berm will be constructed adjacent to the south perimeter of Dry/Wet Mining sub-phase 2A. The
public view or right-of-way face of the berm shall be sloped at a maximum ratio of four(4)feet
horizontal to one(1)foot vertical. The extraction side of the perimeter berm shall be sloped at a
maximum ratio of three(3)feet horizontal to one(1) foot vertical.Upon completion of berm
construction, excess black dirt and overburden material will be stockpiled adjacent to the active
sub-phase. Since the berm associated with Dry/Wet Mining sub-phase 2A will remain permanently
in place for more than 15 years it will be landscaped on the public view right-of—way side with a
density of one tree per 625 square feet with a minimum of 66%of the trees being conifers.
Permanent Berms will be constructed on a phase by phase basis and in some instances the berm
may extend past the required coverage for the active mine phase.In these instances,the installation
3
of trees will occur to the point at which berm construction and landscaping is required to
sufficiently screen the active mine phase. All berms constructed will be vegetated regardless of
whether or not the berm is part of the screening for the active mine phase.
North Dry Mining Phases IA, 1B,2C&2D
Activities related to North Dry Mining Phases 1A, 1B,2C&2D will include relocation of surface
soils,crushing,mixing, screening, stockpiling, aggregate washing,loading,hauling and conveying
of aggregate materials to the Ancillary Use Facility(AUF)or hauled out by use of the Akron
Avenue internal haul/rail bed road corridor.
Generally,the Akron Avenue rail bed corridor access point associated with the North Dry Mining
Phases will be used in relation to specific construction projects and will not be utilized for normal
retail product sales. It is anticipated that 2014 construction activities will include construction of
the internal haul road along the existing rail bed corridor which will provide access to the Akron
Avenue/County Road#42 access location.
The existing stands of trees abutting the North Dry Mining Phases(1A,1B,2C,2D)will sufficiently
screen the proposed phases however additional temporary berms may by established outside of the
proposed phase for additional temporary screening.
3. Haul Routes/Access Locations
The access points to and from the AUF will occur at the intersection of County Road#46 at Akron
Avenue and at the intersection of County Road#46 at Station Trail. With the proposed mining
operation spanning approximately 1.5 miles north to south and approximately 1.5 miles west to
east,North Dry Mining will utilize access locations for ingress and egress to North Dry Mining
phases 1-7.
During mining operations in the North Dry Mining Phases,the area depicted as future Boulder Trail
will remain open and will serve as an internal haul road for material hauling activities utilizing the
Boulder Trail/Biscayne Avenue access location for access to CSAH#42. The access at Akron
Avenue and County Road#42 will be utilized at the commencement mining of the North Dry
Mining phases. In order to access Akron Avenue from the North Mining Area,an internal haul
road will be constructed along the existing rail bed corridor which abuts North Dry Mining sub-
phase lA in the northeast corner. The Boulder Trail and Biscayne Avenue access will not be
utilized until a traffic signal has been installed at Biscayne Avenue at County Road#42. Only one
of these access points will be open for mining activities at any given time.
The internal haul routes for North Dry Mining phases 1-7 will be maintained by the operator as
needed and a water truck will be utilized to control potential haul road dust. Once all of the
saleable material has been extracted and removed from North Dry Mining Phases 1-7,the future
Boulder Trail haul road and other internal haul roads will be reclaimed as per the interim use
reclamation plan within 12 months.

EXCERPT OF DRAFT MINUTES
PLANNING COMMISSION REGULAR MEETING
NOVEMBER 26, 2013
b. Request by Dakota Aggregates for a Large Scale Mineral Extraction Annual Operating Permit
for 2014(13-33-ME). Dakota Aggregates has applied for the annual renewal of their large scale
mineral extraction permit on the UMore property. In 2013,the mining was limited to the area along
County Road 46 and Station Trail. For 2014,Dakota Aggregates is proposing to expand more into
the area adjacent to County Road 46 and Station Trail and also begin mining about'A mile south of
County Road 42. Senior Planner Zweber reviewed the staff report.
Commissioner Husain asked about the potential to have haulback material in 2014 and where in the
mining site it would occur. Mr. Zweber replied that he would refer the question of location to the
applicant but that it would likely occur in the north dry mining area rather than the dry/wet mining
area to the south. Staff tries to set up mineral permits equally and haulback was included in this
permit as a future potential,not a probability for 2014.
Chairperson Powell asked if all the conditions to this renewal are the same as their original issuance
except for the requirements for the monitoring wells which have been completed. Mr. Zweber
responded that was correct,including the additional locations of mining and permits they are
required to get.
Commissioner Weber asked for a clarification of the buffering around the mining areas to the west
and north. Mr. Zweber showed on the map where the berms are located.
The public hearing was opened at 7:08p.m.
Applicant, Shawn Dahl with Dakota Aggregates, stated that with respect to haulback, they have the
ability to facilitate it when the need arises but they do not have any haulback in line at this time and
the dry/wet mining area would never be considered as a haulback area.
There were no comments from the public.
MOTION by Powell to Close the Public Hearing.
Second by Miller.
Ayes: 4. Nays: None. Motion approved. Public hearing was closed at 7:10pm.
MOTION by Weber to recommend the City Council renew the Dakota Aggregates Large
Scale Mineral Extraction Permit for 2014, subject to the terms and conditions in the attached
2014 Draft Conditions for Mineral Extraction.
Second by Miller.
Ayes: 4. Nays: None. Motion approved.
