SUMMARY
Applicant & Property Owner(s): Marlon L. Danner of Danner, Inc.
Location: 4594 145th Street East – one half mile east of US
Highway 52 and one quarter mile south of CSAH 42

Current Zoning: AG – Agriculture
The applicant, Marlon Danner of Danner, Inc., requests renewal of the existing Small Scale Mineral
Extraction permit for 2015. The applicant owns and operates the mine located 4594 145th Street
East, ½ mile east of US Highway 52 and south of CSAH 42. Typically the applicant renews this
permit by late winter each year. Staff contacted the applicant in writing and by phone in June to
remind them the permit had expired and no activity may occur on the site until their permit is
renewed. Danner submitted an application in June without the required soil tests and the
application was deemed incomplete. A complete application including the required soil test was
submitted on August 11th of this year. Staff recommends approval of the request based upon a
review of the information submitted by the applicant, the mineral extraction standards in Section 11-
10-4 of the City Code, City Police records and the attached permit.
PLANNING COMMISSION ACTION
The Planning Commission held a public hearing to review this item on August 25, 2015 that resulted
in no public comment. Staff summarized the application for the Commission and noted that the
permit expired and a site inspection found the applicant was storing dumpsters on the property in
violation of Condition P of the mineral extraction permit. The applicant had agreed to remove the
dumpsters. The Commission asked the applicant about the timeliness of the renewal application and
storage of the dumpsters. Jerry Bachman of Danner, Inc. stated that he had been semi-retired for
the last few years but Danner had recently brought him back to get this, and other applications, back
2
on track. Mr. Bachman stated the applicant will remove the dumpsters as soon as possible and they
are already working on preparing the 2016 renewal application and anticipate submitting it in late
October once the 2015 season is complete. A second site inspection on September 8, 2015 found
the dumpsters were removed and the site is in compliance with all the conditions of the 2015 small
scale mineral extraction permit.
BACKGROUND
According to the applicant, the Danner site experienced a 25 percent increase in activity during
2014. Mining continued in Phase One and the eastern half of Phase Two and resulted in the
applicant removing approximately 40,000 tons of sand and rock from the pit last year. Danner also
continues to import material to the site for future reclamation. In 2014, Danner hauled back
approximately 10,000 yards of excess material from their South St. Paul location. This material
originally came from a 3 year old St. Paul project. As required by the permit, the applicant has
submitted soil tests of this material conducted by Braun Intertec which conclude it meets the
requirements of both the permit and reclamation protocol.
ISSUE ANALYSIS
Aggregate mining is reviewed through an interim use permit which is Quasi-Judicial actions. As
such, the City has a set of standards and requirements for review. Generally, if the application meets
the ordinance requirements it must be approved. The standards and requirements for this mineral
extraction are detailed in Section 11-10-4 of the Zoning Ordinance and the attached Mineral
Extraction permit.
The subject property is zoned AG – Agriculture and meets or exceeds the applicable performance
standards for small scale mineral extraction. Small scale mineral extraction is listed as an interim use
within the Agriculture district. The table below details the current land use, zoning, and future land
use information for the surrounding properties. These properties are all currently zoned
Agricultural or Agricultural Preserve and are located within the 2030 Metropolitan Urban Service
Area (MUSA). The 2030 Future Land Use Map anticipates a mixture of residential and business
park uses in this area.

Access to the Danner mine comes from County Road 42 via a gravel road along the eastern edge of
the property. This road is shared with the Ped/Kuznia (SKB) mine to the west. The applicant
maintains a private access agreement with the Ped/Kuznia property to coordinate mining levels and
allow continued access to both the sites.
The annual renewal for mineral extraction permits includes a site inspection and consultation with
the Rosemount Police Department regarding any police activity. Police records noted no activity at
the subject property in 2014 or to date in 2015. A site visit on August 18, 2015 with representatives
of Danner noted storage of dumpsters in violation of Condition P. During the Planning
Commission meeting, the applicant agreed to remove the dumpster prior to City Council review. A
3
second site inspection on September 8, 2015 found the dumpsters have been removed the site is in
compliance with all the conditions of the 2015 small scale mineral extraction permit.
RECOMMENDATION
Both the Planning Commission and staff recommend approval of this request based upon a review of
the information submitted by the applicant, the mineral extraction standards in Section 11-10-4 of the
City Code, City Police records and the attached permit.

PLANNING COMMISSION REGULAR MEETING
AUGUST 25, 2015
5.a. Request by Danner for a Small Scale Mineral Extraction Permit Renewal for 2015.(15-25-ME)
Planner Lindahl summarized the staff report for the Planning Commission. The property is located east of
Highway 52 and south of 42. The site has been mined in multiple phases. The mine extracted
approximately 40,000 tons last year. Soil tests have been done and meet standards. Research by staff
indicates no complaints to the police department. A site inspection found the applicant was storing
dumpsters on the property in violation of Condition P for the mineral extraction permit. Commissioner
Kenninger inquired whether there was activity during the time that the permit had lapsed. Lindahl stated
that there had been until staff had contacted them regarding the lapse and they stopped after that.
Commissioner Kenninger asked about the insurance certificate dates. Lindahl indicated that is a typo and
staff will correct.
Commissioner Kurle inquired whether the mining would stay in the area indicated. Lindahl stated that the
permit limited mining to Phase One and the eastern half of Phase Two.
Chair Miller inquired if there were any changes from the earlier permit. Lindahl stated there were not.
The public hearing was opened at 6:39 pm.
Public comments:
The applicant, Jerry Bachman, 880 Casper Way Heights, Inver Grove Heights, working for Danner
Incorporated. Mr. Bachman represents the applicant and apologized for the delay in the application.
Commissioner Miller asked Mr. Bachman what steps would be taken to maintain compliance by Danner
Inc. Mr. Bachman stated that he has spoken with staff already regarding the 2016 permit and has spoken
with the bond, insurance and testing companies, as well. Commissioner Kenninger asked about the
dumpsters being stored there and whether they would definitely be removed this week. Mr. Bachman
stated they would.
MOTION by Kenninger to close the public hearing.
Second by Kurle.
Ayes: 6. Nays: 0. Motion Passes.
The public hearing was closed at 6:43 pm.
Additional Comments:
Commissioner Miller inquired about the dusk control plan. Lindahl stated the plan from last year remain s
in effect and there have been no dust related complaints about the property.
Commissioner Miller inquired about adding the condition that a plan for dust control will be implemented
and maintained. Mr. Lindahl stated that this was standard language, but if the commission wished, they
could recommend that to the City Council. Mr. Bachman stated they did repave the road recently and this
work decreased the dust significantly.
Motion by Kenninger to recommend the City Council renew the Danner Small Scale Mineral Extraction
Permit for 2015, subject to the terms and conditions in the attached Draft 2015 Conditions for Mineral
Extraction, with modification to O, changing the dates to read January 1 st, 2015, to July 31st, 2016, and

Re: Borrow Pit Reclamation – Stockpile Summary Letter
4594 145th Street East
Rosemount, Minnesota
Dear Mr. Danner:
Per your request, Braun Intertec Corporation collected soil samples from stockpiled soil located at the
above referenced property (Site) in Rosemount, Minnesota. A Site Location Map is included in
Attachment 1. The purpose of the soil sampling was twofold. In order to obtain a2015 Small Scale
Mineral Extraction Permit, Danner, Inc. is required to document that their 2014 “haul back” material
meets all the requirements of the 2014 Conditions for Small Scale Mineral Extraction Permit for Danner,
Inc. and the Danner Inc. Borrow Pit Reclamation Protocol Rosemount, Minnesota (2014 Protocol). The
2014 Protocol includes environmental testing and observation of “haul back” material. Second, the
sampling will help with Danner Inc.’s reclamation end-goal for the borrow pit which includes creating
prepared building pads for light commercial construction (as noted in the 2014 Protocol’s Protocol
Guiding Principles).
Background
Based on conversations with the Site owner, during 2014, an estimated 10,000 to 12,000 cubic yards of
“haul back” soils were received from local municipalities’ road-improvement projects and other
redevelopment projects (2014 stockpile soil). The 2014 stockpile soil was transported to the Danner Pit
located at 843 Harman Avenue South, South St. Paul, MN for temporary storage. A list of projects is
included in Attachment 2.
On October 1, 2014, three soil samples (labeled as STOCK-1 through STOCK-3) were collected from the
2014 stockpile soil. Results of this sampling event can be found in the summary letter titled Borrow Pit
Reclamation – Stockpile Summary Letter, 843 Hardman Avenue South, South St. Paul, project B14-07375
and dated October 24, 2014. The 2014 stockpiled soil was later transported to the Danner Reclamation
Pit located at 4594 145th Street in Rosemount, MN.
Sampling Procedures
On July 27, 2015, four test pits were excavated using a track-mounted back-hoe operated by a Danner,
Inc. employee within the 2014 stockpiled soil located at the Site. Test pits excavated within the 2014
stockpiled soil ranged in depth between 5 feet and 12 feet below the top of the stockpile and were
approximately 4 feet wide by 10 feet in length.

Test pits were located so that they cut through the stockpile in each location. A Braun Intertec
environmental scientist observed the tests pits and the 2014 stockpiled soil for unusual staining, odors,
and other apparent signs of contamination. Select soil samples were collected and screened for the
presence of organic vapors using a photoionization detector (PID) equipped with a 10.6-electron-volt
lamp and calibrated to an isobutylene standard. The PID was used to perform a headspace method of
field-analyses, as recommended by the Minnesota Pollution Control Agency (MPCA) in Petroleum
Remediation Program Guidance Document 4-04 (September 2008). Stockpiled soils also were observed
for the presence of debris including but not limited to ash, metal, brick, concrete, and/or glass.
The stockpile soil samples were submitted to a certified laboratory for the following parameters:
Diesel-range organics (DRO) using the Wisconsin Department of Natural Resources (WDNR)
Method.
Gasoline-range organics (GRO) using the WDNR Method.
Volatile-organic compounds (VOCs) using United States Environmental Protection Agency
(EPA) Method 8260.
Resource and Recovery Act (RCRA) Metals using EPA Methods 6010.
Polyaromatic Hydrocarbons (PAHs) using EPA Method 8270.
Summary and Analytical Results
Four soil samples, labeled Stockpile 4 through Stockpile 7 were collected at the Site. No elevated PID
readings, odor or staining were observed from the areas where the samples were collected. Soils
encountered within the 2014 Stockpile consisted of silty sand with minor amounts of clay, gravel, and
cobbles. Soil observed within the four test pits appeared to be fairly uniform.
For comparison purposes, chemical components detected in the soil samples are compared with their
respective MPCA Industrial Soil Reference Values (SRVs) and Soil Leaching Values (SLVs). The SRVs and
SLVs are allowable risk-based contaminant concentrations derived by the MPCA using risk assessment
methodology, modeling, and risk management policy to guide Site investigation and cleanup actions. The
SRVs and SLVs are expressed as a concentration in milligrams per kilogram (mg/kg).
The results of the laboratory analysis indicated that:
DRO was detected in soil sample stockpile 4 at concentration of 14.6 mg/kg.
Several PAHs were detected at concentrations greater than or equal to the laboratory
method reporting limits (MRLs); however, the concentrations detected did not exceed their
applicable Industrial SRVs, where established. In addition, the calculated Benzo(a)pyrene
(BaP) equivalent did not exceed the established Industrial SRV.
Varying concentrations of the eight RCRA metals were detected in the soil samples; however,
none of the concentrations detected exceeded their respective Industrial SRVs and/or SLVs.
