Review Process
Application Received: January 12, 2023
Acceptance of Completed Application: January 12, 2023
Tentative City Council Date: February 1, 2023
60-Day Review Deadline: March 13, 2023
Ordinance Requirements
City Code Title 3-9 requires that an annual mining permit must be reviewed by the Planning Com-
mission within 60 days after the completed application has been accepted by the City. The Plan-
ning Commission's recommendation is forwarded to the City Council for final action. The purpose
of the annual mining permit is to:
• Ensure the restoration of the mined area is consistent with existing and planned land use
patterns and to promote appropriate reuse of the mined areas
• Ensure conformity of mining operations with the City's Critical Area and Comprehensive Plans
• Control the effects of noise, dust, erosion, traffic, drainage, ground water pollution, and other
factors related to mining in general
Background
Mining at the existing Nelson Sand and Gravel Mine Facility has occurred since the early 1950s
when the J.L. Shiely Company (now known as Holcim Industries) entered into a lease agree-
ment with the private landowner. A form of this lease agreement remains in place between the
private landowner and Aggregate Industries today. On October 12, 1982, the Lower Grey Cloud
Island Reclamation Concept Plan was approved by a City of Cottage Grove Reclamation Commit-
tee. A mining plan prepared by B.B. Chapman in 1982 is part of that document. A copy of this plan
is shown below. With some exceptions, the proposed 2023 Operations Plan generally replicates
landforms and topography as approved in 1982.

Mining Operations
Mining Operations consist of dredging to excavate raw aggregate materials. The dredge is used
to reach sand reserves below the water surface. Its de -sanding capability and initial crusher that
crushes rocks to smaller than six inches in size allows the operator to reclaim up to 400 tons of
sand per hour without unnecessary re -handling. The dredge can mine 1,200 tons of aggregate
material per hour at 60 feet below the water surface. After the material is excavated by the
dredge, the mined aggregate is transported by a conveyor system that is about 2.2 miles long to
the processing plant located at the northwest side of Lower Grey Cloud Island. The processing
operations include crushing, washing, sorting, and stockpiling aggregate materials by size.
These materials are then loaded onto barges or trucks. Most of the material is transported by
barge up the Mississippi River to distribution yards in St. Paul
In 2023 the Applicant will add an additional piece of mining equipment at the facility. A DRAGA
2030 fully electric floating suction dredge will be utilized to move waste sand overburden from
an area which was previously mined in the 1970s to 1980s. The suction dredge will have the
ability to reach depths of 60 feet below water and will work in conjunction with the existing
dredge. While the existing dredge will continue to mine material for processing and sale, the
new suction dredge will be used solely to pump a slurry of overburden sand and water away
from the active mining area. The overburden sand moved by the suction dredge will be placed in
areas to support the final reclamation of the site.
Annual Mining Report
In 2022, approximately 607,000 tons of aggregate were transported up the river while approxi-
mately 60,000 tons were transported by truck.

Planning Considerations
Proposed Mining Operations
The 2023 Operation Plan is shown on the next page and a copy is attached to this planning staff
report.
Proposed 2023-2024 Operations Plan
As shown above, the proposed mining activity will shift to the west from the 2022 location. Like
previous operation plans, the applicant is required to take appropriate measures to ensure there is
no erosion to stockpiles or earth -berms. At the base of each slope, a channel must be constructed
to control runoff. The channeled water shall be diverted to a sedimentation basin before being al-
lowed to enter any natural drainage system. Erosion control measures must be implemented within
a reasonable amount of time for the stockpile and berm.
Environmental Impact Statement Process
The Applicant is in the process of working on an Environmental Impact Statement for proposed
expansion of their mining operations in the Mississippi backwaters, located to the southeast of the
existing facility.
Reclamation Plan
As of 2023, approximately 265 acres of the site have been reclaimed. The 2023 restoration plans
include ongoing restoration efforts in creating a large lake and peninsula by providing shore stabili-
zation/establishment and re -vegetation. Continued restoration in the areas of the oak
grove/savanna and prairie will continue to take place as depicted in the 2023 operation plan. The

Applicant also continued treatment of invasive Siberian Elm, Black Locust, and brush species. This
treatment work took place in the previously reclaimed areas along the eastern perimeter of the site.
Nuisance Noise Complaints
The Public Safety Department reported that there were no noise complaints related to the 24-hour
mining that occurred in 2022.
Meeting Notices
The meeting notice was mailed to 18 property owners who are within a half -mile of the mine on
January 11, 2023. Staff has not received any comments at the time of writing this report.
City Department Review
Aggregate Industries' 2023 mining permit application was distributed to other City departments.
No comments were received.
Recommendation
It is recommended that the 2023 Mining Permit for Holcim — MWR, Inc. — Nelson Sand and Gravel
Facility located at 11250 Grey Cloud Trail be approved, subject to the following conditions:
1. The provisions as stipulated in Title 3, Chapter 9 of the City's Codes (Mining, Sand, and
Gravel Operation) shall be complied with, except as modified below.
2. The applicant is responsible for removing any materials that their equipment and/or trucks
may have spilled onto any public roadway. This material shall be cleaned up immediately.
3. The outer limits of their mining operations must be a minimum of 100 feet from abutting pub-
lic right-of-way, private property, or any archeological sensitive area.
4. City approval of the 2023 Mining Permit does not approve their ability to mine within the re-
quired 200-foot setback from the Mississippi River, within the Mississippi River itself, or in
the vicinity of archeological sensitive areas.
5. Bituminous/asphalt, concrete, and street sweepings originating within the geographical
boundaries of Cottage Grove may be temporarily stockpiled on the site for processing (e.g.,
crushing, screening, etc.) and/or reuse. Bituminous/asphalt materials are prohibited from
being buried on the premises.
6. The applicant may operate the mining operation 24 hours a day, 7 days a week. Upon noti-
fication by neighboring residents that the night-time operations (i.e., between the hours of
10:00 p.m. and 6:00 a.m.) are disturbing, the applicant agrees to voluntarily cease operation
during night-time hours until such time the noise source is identified and appropriate correc-
tions are made.
7. Aggregate Industries must install erosion control devices at the base of any slope where
erosion is evident. A drainage swale must be constructed at the base of any eroding slope
to control run-off and divert it to a sedimentation basin before entering any natural drainage

system. Erosion control measures must be implemented within a reasonable amount of
time.
8. Archeological and landmark sites as identified in the burial mound group known as
21 WA9 and the recorded Grey Cloud Townsite 21 WA48 on Lower Grey Cloud Island
must be protected and undisturbed, and protected from being damaged or adversely im-
pacted from vehicles or equipment traveling in the vicinity of these historic sites.
9. The applicant is responsible for obtaining all state and federal permits relating to their
mining operations on Lower Grey Cloud Island.
10. The applicant's current reclamation plan is titled "Future Land Use Plan." The City has
not provided any formal review or approval of the "Future Land Use Plan." This concept
plan is only an illustration of a development concept that the applicant and landowner
have considered. The City's approval of the 2023 Operations Plan does not guarantee
approval or imply future approval of the Harbor Island Concept Plan or the Future Land
Use Plan as dated July 18, 2017 and prepared by Westwood Professional Services.
11. The Oak Savanna Reclamation Plan, revised 9-3-2010, is still valid. All oak plantings that
have not survived within the designated oak savanna groves must be replaced with new
oak trees and watered during dry conditions to promote their survival. As the Oak
Savanna Reclamation Plan is implemented, the applicant must continue to update the
City on the effectiveness of the reclamation and restoration activities, particularly how
many acorns are planted and how many oak seedlings are growing. If the survival num-
ber of trees is low, then another tree planting alternative will need to be discussed.
12. Depositing fill materials within the floodway and floodway fringe (below the 700-foot mean
sea level elevation) is prohibited.

Mining Operations -A
Holcim — MWR, Inc.'s (formerly Aggregate Industries) Nelson Sand & Gravel Facility
excavates and processes aggregate materials which are utilized for ready mix concrete and/or
asphalt products for the construction of highways and buildings within the Twin Cities
metropolitan area.
The Company currently estimates that mining will continue for another estimated four years.
These estimate are based on current information and are subject to market trends, geologic
variations and the expansion of reserves, as additional exploration occurs. At this time, the
Company is in the process of working on an Environmental Impact Statement for their proposed
mining in the Mississippi backwaters, located to the southeast of the existing facility.
The dredge at this facility will continue to carry out the mining into the foreseeable future. On
the dredge the material is initially crushed to smaller than 6 inches in size and the excess sand is
then screened off and pumped to the south shoreline or into the deepest part of the excavation for
reclamation. The coarse aggregate blend is then conveyed to the processing plant where it is
crushed, washed, sorted by size and loaded onto barges. The Plant is expected to produce
approximately 700,000 to 750,000 tons of aggregate material in 2023.
In 2023 Holcim will add an additional piece of mining equipment at the Nelson facility. A
DRAGA 2030 fully electric floating suction dredge will be utilized to move waste sand
overburden from an area which was previously mined in the 1970's — 1980's. The suction
dredge will have the ability to reach depths of 60 feet below water and will work in conjunction
with the existing clamshell dredge. While the existing clamshell dredge will continue to mine
material for processing and sale, the new suction dredge will be used solely to pump a slurry of
overburden sand and water away from the active mining area. The overburden sand moved by
the suction dredge will be placed in areas to support the final reclamation of the site.
3
The majority of the material from the Nelson Sand & Gravel facility is transported by barge up
the Mississippi River to the Company's distribution yard in St. Paul. In 2022, roughly 607,000
tons of aggregate were transported by barge. In addition, roughly 60,000 tons were transported
by truck on Grey Cloud Trail South to 103rd Street, east to Hadley Avenue, north to 1001h Street,
then to U.S. Highway 61.
The Company has mined around and past the area that was thought to have the greatest potential
as the site of the historic town site Town Site 21 WA48. As mining progresses to the west, the
area that is identified as the Burial Mound Group 21 WA9 will be left undisturbed.
Reclamation
The 2023 Operations Plan shows the area where the former St Croix Crossing Casting Plant and
yard was located as "Operational Area." That area will not be reclaimed for several years. It
will be utilized for additional product storage and will be filled with 3 to 5 feet of waste sand or
dredge sand before it is ultimately reclaimed. The 2023 Operations Plan depicts roughly 265
acres which have been reclaimed to date.
The Landowner's current plans for reclamation of Lower Grey Cloud Island are depicted on the
"Lower Grey Cloud Island Plan" prepared by Westwood Professional Services and the "Harbor
Island Concept Plan." These concepts propose a planned unit development of mixed residential,
commercial and marina uses. The Company's reclamation efforts will follow this concept in
general terms.
Ongoing reclamation efforts will continue in 2023 and beyond by creating the large lake and
peninsula, as well as slope and shore stabilization/establishment and re -vegetation. The ultimate
lake shape will be similar, but smaller than that which is depicted on the attached Mining Plan by
B.B. Chapman. All slope reclamation will be at 4:1 or flatter.
Waste sand will continue to be placed in the area north of the conveyor for the next 2 to 3 years
until that area can be contoured to blend with the high ground to the north and east. That area
will be sloped gradually from northeast to southwest at an elevation substantially above the 100-
year flood plain.
Since 2010 the Company has been working towards the re-establishment of an Oak Savanna and
a prairie area at the Nelson facility. Essentially, all reclamation of the uplands on the disturbed
areas of Lower Grey Cloud Island will focus on the re-establishment of an oak savanna and
prairie. The Company continues to work with Great River Greening with these reclamation
efforts. Annual contributions have included and will continue to include: soil preparation, native
grass seeding, oak plantings, herbicide treatment of non-native vegetation, brush and tree
removal of non-native woody species and maintenance burns.
In 2020, a new oak grove was established in the area located northeast of the waste sand area as
depicted on the 2023 Operations Plan. In 2021, the Company planted an additional eight 6' oak
trees in the oak grove. Maintenance work of these planted oaks took place in 2022, which
4
consisted of watering throughout the season with cage maintenance (where necessary). This oak
grove replaced the:fornT,er I:'nter'ac,'nen Pr°anr;ic4 anta w,�. chs was'ecat--d withnr, the wzste sand area.
Foliar treatment of invasive Siberian Elm, Black Locust and brush also continued in 2022. This
foliar treatment work took place in the previously reclaimed area along the eastern perimeter of
the site. This work consisted of a late spring cut -and -treatment of 'arger spe:;js°ayns, fol'.o°red bar
