In such case, the Contractor General Conditions 00700 - 10 Rolling Hills Pond Dredging Ell< River, Minnesota shall not be entitled to receive any further payment until the work is finished. If the unpaid balance of the contract price exceeds the direct and indirect costs of completing the project, including compensation for additional professional services, such excess shall be paid to the Contractor. If such costs exceed such unpaid balance, the Contractor will pay the difference to the Owner. Such costs incurred by the Owner will be determined by the Engineer and incorporated in a Change Order. 18.3 Where the Contractor's services have been so terminated by the Owner, said termination shall not affect any right of the Owner against the Contractor then existing or which may thereafter accrue. Any retention or payment of monies by the Owner due the Contractor will not release the Contractor from compliance with the Contract Documents. 18.4 After ten (10) days from delivery of a written notice to the Contractor and the Engineer, the Owner may, without cause and without prejudice to any other right or remedy, elect to abandon the project and terminate the Contract. In such case, the Contractor shall be paid for all work executed and any expense sustained plus reasonable profit. 18.5 If, through no act or fault of the Contractor, the work is suspended for a period of more than ninety (90) days by the Owner, or under an order of court or other public authority, or the Engineer fails to act on any request for payment within thirty (30) days after it is submitted, or the Owner fails to pay the Contractor substantially the sum approved by the Engineer or awarded by arbitrators within thirty (30) days of its approval and presentation, then the Contractor may, after (10) days from delivery of a written notice to the Owner and the Engineer terminate the Contract and recover from the Owner payment for all work executed and all expenses sustained.

Payment to Contractor 19.1 At least ten (10) days before each progress payment falls due (but not more often than once a month), the Contractor will submit to the Engineer a partial payment estimate filled out and signed by the Contractor covering the work performed during the period covered by the partial payment estimate and supported by such data as the Engineer may reasonably require. If payment is requested on the basis of materials and equipment not incorporated in the work but delivered and suitably stored at or near the site, the partial payment estimate shall also be accompanied by such supporting data, satisfactory to the Owner, as will establish the Owner's title to the material and equipment and protect General Conditions 00700 - 11 Rolling Hills Pond Dredging Ell< River, Minnesota the Owner's interest therein, including applicable insurance. The Engineer will, within ten (10) days after receipt of each partial payment estimate, either indicate in writing approval of payment, and present the partial payment estimate to the Owner, or return the partial payment estimate to the Contractor indicating in writing the reasons for refusing to approve payment.

The Owner will, within ten (10) days of presentation of an approved partial payment estimate, pay the Contractor a progress payment on the basis of the approved partial payment estimate less the retainage. The retainage shall be an amount equal to 5% of said estimate. At any time when the progress of the work is not satisfactory, additional amounts may be retained. Upon substantial completion of the work, any amount retained may be paid to the Contractor. When the work has been substantially completed except for work which cannot be completed because of weather conditions, lack of materials, or other reasons which in the judgment of the Owner are valid reasons for non -completion, the Owner may make additional payments, retaining at all times an amount sufficient to cover the estimated cost of the work still to be completed. 19.1.1 The Engineer may disapprove or, on account of subsequently discovered evidence, nullify the whole or part of the approved partial payment estimate to such extent as may be necessary to protect the Owner from loss, on account of - (a) Defective work not remedied.

Such use shall not constitute an acceptance of such portions of the work. 19.4 The Owner shall have the right to enter the premises for the purpose of doing work not covered by the Contract Documents. This provision shall not be construed as relieving the Contractor of the General Conditions 00700 - 12 Rolling Hills Pond Dredging Ell< River, Minnesota sole responsibility for the care and protection of the work, or the restoration of any damaged work except such as may be caused by agents or employees of the Owner. 19.5 Upon completion and acceptance of the work, the Engineer shall issue a certificate attached to the final payment request that the work has been accepted under the conditions of the Contract Documents. The entire balance found to be due the Contractor, including the retained percentages, but except such sums as may be lawfully retained by the Owner, shall be paid to the Contractor within thirty (30) days of completion and acceptance of the work. 19.6 The Contractor will indemnify and save the Owner or the Owner's agents harmless from all claims growing out of the lawful demand of subcontractors, laborers, workers, mechanics, material, men, and furnishers or machinery and parts thereof, equipment, tools and all supplies incurred in the furtherance of the performance of the work. The Contractor shall, at the Owner's request, furnish satisfactory evidence that all obligations of the nature designated above have been paid, discharged or waived. If the Contractor fails to do so the Owner may, after having notified the Contractor, either pay unpaid bills or withhold from the Contractor's unpaid compensation a sum of money deemed reasonably sufficient to pay any and all such lawful claims until satisfactory evidence is furnished that all liabilities have been fully discharged whereupon payment to the Contractor shall be resumed in accordance with the terms of the Contract Documents, but in no event shall the provisions of this sentence be construed to impose any obligations upon the Owner to either the Contractor, the Contractor's surety, or any third party. In paying any unpaid bills of the Contractor, any payment so made by the Owner shall be considered as a payment made under the Contract Documents by the Owner to the Contractor and the owner shall not be liable to the Contractor for any such payments made in good faith. 19.7 If the Owner fails to make payment thirty (30) days after approval by the Engineer, in addition to other remedies available to the Contractor, there shall be added to each such payment interest at the maximum legal rate commencing on the first day after said payment is due and continuing until the payment is received by the Contractor. 20.

Division S S-1 Rolling Hills Pond Dredging Ell< River, Minnesota S-5 Scope of Work The specifications, together with the plans, describe in detail the work to be completed on the project. The Contractor shall be responsible for all work and its proper completion except as explicitly noted. All work shall be completed in accordance with the pertinent federal, state, and local codes and ordinances. In addition to the construction, the Contractor shall protect, maintain, repair, and restore all subsurface and overhead structures directly or indirectly disturbed, damaged, or affected by his operation. The work under this project consists of excavation activities at six municipal stormwater ponds in Elk River, Minnesota. These municipal stormwater ponds are referenced as Rolling Hills Pond Dredging. Rolling Hills Pond Dredging encompasses an area of approximately 10,200 Square Feet at a depth of 2 feet, see site plan for reference. The Rolling Hills ponds have reached the limit of treatment effectiveness and requires maintenance. The sediment testing consisted of 12 composite samples at six different locations. The full assessment of sediment testing is attached as Rolling Hills Sediment Testing. B-1 is considered above Tier 1 SRV and would be classified as "regulated fill." Regulated fill is considered solid waste by the MPCA and required proper disposal. The five other basins are considered Tier 1 and is classified as "unregulated fill," which should follow the MPCA's Best Management Practices for Offsite Use of Unregulated Fill (MPCA BMP Guidance). According to their guidance, the MPCA recommends avoiding placing unregulated fill at schools, playgrounds, daycares, residential properties, in gardens where food will be produced, and near lakes, rivers or streams. The MPCA indicates that unregulated fill is best suited for use at industrial or commercial properties. If the Minnesota Pollution Control Agency SRV standards change during the timeline of the project that affects these standards, the city will retain the option to reconsider with the contractor and MPCA on an appropriate solution. The contractor will furnish all labor, equipment and materials to perform the requested excavation in accordance with the approved permit conditions. Contractor shall properly dewater the pond prior to excavation and may have to continue dewatering if groundwater is encountered during the project. The dredged sediment material must also be adequately dewatered prior to being hauled off site. The excavation shall include providing access for equipment from the banks of the pond, repairing the bank as can be accomplished during winter conditions, and excavating the pond until the native bottom is reached. The contractor shall be responsible for determining the best methods and equipment to use with a goal of maximizing the area of excavation. The contractor shall also be responsible for providing trucking of spoils to a suitable location selected by the contractor and allows for proper disposal. The contractor shall be responsible for compliance with all project permit conditions including, but not limited to, meeting all environmental standards.

Brandon Wisner, Engineering Project Manager, requested engineering assistance to complete this project. On September 8, 2023, the Client authorized American Engineering Testing, Inc. (AET) to provide environmental services for characterizing sediments in the stormwater pond so that the dredged sediments may be managed properly upon removal. Figure 1 shows the location of the stormwater pond sampling locations in the Rolling Hills Development (Site). The Site is a residential area, approximately 30 acres in size. The stormwater ponds are spread out through the development, with each pond less than 1 acre in size. Most of the ponds are overgrown with wetland vegetation and little standing water. 2.0 SCOPE OF SERVICES AET performed a sediment assessment in general accordance with the May 2017 Minnesota Pollution Control Agency (MPCA) document Managing Stormwater Sediment Best Management Practices Guidance, wstrm4-16 (May 2017 Stormwater Sediment Guidance). The scope of services completed by AET consisted of: • Collecting two samples from each pond, for a total of twelve (12) sediment samples. Samples were collected to depths of 2.0 feet below the pond bottom, or native soil. The borings were advanced at the inlet and outlet of each stormwater pond. Each sample location was logged in one -foot intervals noting sediment types and other characteristics (i.e. staining, odors). • Collecting a sediment sample from each of the borings for laboratory analysis of arsenic, copper, polynuclear aromatic hydrocarbons (PAH), and carcinogenic polynuclear aromatic hydrocarbons (cPAHs). • Preparing this report presenting the testing results and recommendations for managing sediment/soil dredged from the stormwater pond and the expansion area. 3.0 SEDIMENT SAMPLING AND TESTING 3.1 Sediment Collection AET collected a total of twelve (12) samples, two from each of six stormwater ponds (Figure 1). The City of Elk River provided a Rolling Hills Development plan sheet which showed the pond locations. Samples were collected from borings advanced 0 to 2 feet into the pond sediment. In general, all the encountered pond sediment was silty or clayey sand with varying amounts of organic material. Appendix A provides a general description of sampling methods used during this project. Page 1 of 4 Rolling Hills Development Environmental Sampling Report Elk River, Minnesota October 10, 2023 AET Report No. P-0025977 eAM E R IC.4N no1neersana resrino- 3.2 Classification Methods Sediment samples obtained in the field were visually/manually classified in general accordance with the Unified Soil Classification System (USCS) described in ASTM: D 2488. Soil screening notes are included in Appendix C. 3.3 Laboratory Analysis AET submitted one sediment sample from each of the two hand augers advanced in the stormwater pond area to Pace Analytical for laboratory analysis of the following parameters: • arsenic • copper '31 cPAHs Appendix B includes the laboratory analytical report. 3.4 Reference Standards In this report, we compare the analytical results to the baseline environmental regulatory standards in use by the MPCA. The reference standards are included in the results tables for comparison with assessment results. The following reference standards apply to potential contaminant exposures in soils: MPCA Tier 1 Residential Soil Reference Values (SRVs): Compound -specific values for long- term soil exposure in unrestricted -use settings (i.e., residential) above which an unacceptable risk to human health is predicted to exist. Soils below Tier 1 SRVs are suitable for reuse in residential settings. • MPCA Tier 2 Industrial SRVs: Compound -specific values for long-term soil exposure in industrial -use settings above which an unacceptable risk to human health is predicted to exist. Soils below Tier 2 SRVs are suitable for reuse in industrial settings. • MPCA Tier 1 Screening Soil Leaching Values (SLVs): Compound -specific values in unsaturated soils above which an unacceptable risk of leaching to groundwater and/or receptors is predicted to exist. 4.0 RESULTS 4.1 Sample Locations Sample locations were selected at the inlet and outlet of each pond. AET scouted these locations and was able to access all locations for sampling. Page 2 of 4 Rolling Hills Development Environmental Sampling Report Elk River, Minnesota October 10, 2023 AET Report No. P-0025977 AIM IN SCAN €HGINEEHlNG TESTING 4.2 Sediment Description The sediments encountered at all locations were mostly silty sand or clayey sand with organic material. Sediments encountered at B-3a and B-3b were more saturated than the other sites. 4.3 Analytical Results AET submitted one sample from each boring location (12 total) for laboratory analysis. Laboratory analytical results are shown in the attached Table 1 and compared to regulatory criteria published by the MPCA. The laboratory reports are included as Appendix B. 4.3.1 PAHs Various PAHs were detected in each sample. Most individual parameters were not detected above their respective Tier 1 Residential/Recreational SRVs or Tier 1 SLVs. However, the BaP equivalent was calculated for each sample based on the PAHs detected. The calculated BaP equivalent was above the Tier 1 Residential/Recreational SRV and Tier 1 SLV in B-1A. 4.3.2 Metals Arsenic and copper were detected at varying concentrations in the sediment samples analyzed. None of the concentrations detected exceed their respective Tier 1 Residential/Recreational SRV or Tier 1 SLV. 5.0 DISCUSSION/CONCLUSIONS The calculated BaP equivalent for one sample (B-1A) was above the Tier 1 Residential/Recreational SRV and Tier 1 SLV. Arsenic and copper were detected in each of the samples collected at concentrations below their respective Tier 1 Residential/Recreational SRVs and Tier 1 SLVs. Both metals occur naturally in the environment and the measured concentrations of arsenic and copper appear to be consistent with typical background concentrations. Based on the laboratory analysis of sediment samples, most of the excavated sediment from the ponds would be classified as "unregulated fill" and re -use of this material should follow MPCA's Best Management Practices for Offsite Use of Unregulated Fill (MPCA BMP Guidance). According to their guidance, the MPCA recommends avoiding placing unregulated fill at schools, playgrounds, daycares, residential properties, in gardens where food will be produced, and near lakes, rivers or streams. The MPCA indicates that unregulated fill is best suited for use at industrial or commercial properties. The MPCA BMP Guidance is attached (Appendix D). Excavated sediments from areas near B-1A would be classified as "regulated fill". Regulated fill is considered solid waste by the MPCA and requires proper disposal. Page 3 of 4 Rolling Hills Development Environmental Sampling Report Elk River, Minnesota October 10, 2023 AET Report No. P-0025977 AIM IN SCAN €HGINEEHlNG TESTING 6.0 RECOMMENDATIONS During excavation, the water level should be kept below any outlets of the stormwater management area for the duration of the sediment excavating activity, or the discharge must be protected or controlled in such a manner as to prevent turbid water and/or dredged sediment from being released to a water resource. We recommend the water in the stormwater management area be drained as much as possible. The MPCA May 2017 Stormwater Sediment Manual recommends that best management practices (BMPs) for erosion and sediment control should be employed at the site as well as the location where sediment is temporarily stockpiled. The MPCA also recommends that records of all dredge projects (e.g., reports, permits, plans, waste manifests, etc.) be maintained by the owner and operator of the stormwater management facilities. 7.0 STANDARD OF CARE The data derived through this sampling program have been used to develop our opinions about subsurface conditions. However, because no sampling program can reveal totally what is in the subsurface, conditions between samples, and at other times, may differ from conditions described in this report. The sampling we conducted identified soil conditions only at those points where we took samples. Depending on the sampling methods and sampling frequency, every soil type may not be observed, and some materials or layers which are present in the ground may not be documented. AET has endeavored to perform services for this project in a manner consistent with the level of skill and care ordinarily exercised by other members of the profession currently practicing in this area, under similar budgetary and time constraints. No additional warranty, express or implied, is made. This report is based on our current understanding of the project. If conditions differing from our original understanding or findings are identified, AET should be consulted to determine if there are material impacts on our conclusions or recommendations.

Frequent visual and verbal contact is maintained with operators of heavy equipment in the sampling vicinity. Care is taken not to enter depressions or scale mounds that would constitute confined spaces, where engulfment, immersion, or falls are possible, or where harmful vapors may collect. Most observations and soil collection are performed from a stable and level ground surface with the help of heavy equipment operated by an excavation contractor. Contamination Reduction Sampling devices (except heavy equipment in most cases) are cleaned between sampling points to minimize cross contamination. The cleaning procedure may consist of an alconox detergent -water wash using a brush, followed by a tap water rinse. Certain types of projects may entail more or less stringent decontamination procedures. Soil Collection Most soil samples from excavations or test pits are collected directly from heavy equipment (e.g., excavation bucket, loader, or bulldozer), giving preference to soils that have not touched the equipment. A hand auger is used to complete shallow soil borings in locations of limited vehicle access. Hand auger borings are advanced manually, typically in 6" to 12" depth intervals. Soils are collected directly from the hollow auger barrel. A spade shovel is used to collect surficial soils (i.e., up to 6" depth). In many cases, soil samples can be collected by hand without added equipment. Impacted soils or buried debris may be present in the ground that are not observed due to the spacing and depths of sampling points. Best judgment determinations, based on known site conditions and past experience in similar situations, do not guarantee identification or removal of all impacts. Soil Classification As the samples are obtained in the field, they are visually and manually classified by the field staff. Representative portions of the samples may be returned to the laboratory for further examination and for verification of the field classification. Soil classifications, visual/odor observations, and information on any groundwater encountered are reported on the Soil Screening Data Sheet or other field notes. Soil Sample Vapor Screening Soil samples collected directly or from equipment are screened with a photoionization detector (PID) for the presence of organic vapors with ionization potentials less than the lamp voltage. The PID is calibrated for direct reading in parts -per -million -volume (PPMv) of a benzene equivalent. Soil samples are collected and screened according to the bag-headspace field screening procedure, which consists of placing freshly collected soil into a polyethylene Whirl -Pak or freezer "baggie" (i.e., bag), sealing the bag to contain an air pocket (i.e., headspace), and allowing 10 to 20 minutes for vapors to disperse from the soil to the headspace. The highest reading upon inserting the PID probe into the bag headspace — typically attained within two to five seconds of probe insertion — is recorded on the Soil Screening Data Sheet or other field notes. Excessive moisture, temperature extremes, ambient vapors, or other unusual field circumstances can affect screening results. Other Field Screening For certain sites, field screening may be conducted for additional parameters in accordance with AET's Field Screening Methods Supplemental information sheet. Soil Sampling for Chemical Analysis Soil samples obtained for chemical analysis are collected directly or from the sampling device into laboratory - prepared containers with appropriate preservatives, according to laboratory protocols. The samples are delivered to the analytical laboratory within prescribed holding times, accompanied by proper chain -of -custody forms. Page 1 of 1 (02/2013) AMERICAN ENGINEERING TESTING, INC. Not all methods summarized on this information sheet are conducted at all sites. Special conditions may also occur which require modifications to these methods. Any descriptions of field methods within the report text take precedence.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL-Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean -Up U - Indicates the compound was analyzed for, but not detected. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited.

Off -site reuse of excess soil as fill or aggregate is a common practice at many development and road construction projects. If no known or potential sources of contamination are identified during environmental due diligence and subsequent field observations, then sampling of excess soil for laboratory analysis is not necessary. However, when excess soil originates from a site with known or potential sources of contamination, characterization of the soil is warranted prior to off -site reuse in order to ensure the protection of public health and the environment. If contamination is detected in the soil, the unregulated fill criteria and best management practices described herein provide a framework for making good decisions about the off -site reuse of the soil. If the soil does not meet the criteria for unregulated fill, the soil should be managed or disposed of in accordance with applicable regulations. Definition of unregulated fill Unregulated fill, for the purpose of this guidance, is defined as excess soil in which a release of contaminants has been identified at concentrations less than the MPCA's most conservative risk -based values (see complete criteria on the next page). Thus, the identified contaminants in the fill are present at concentrations that are not of regulatory concern to the MPCA. Unregulated fill is not a solid waste.* Exclusions 1. Some excess soil and other material generated at a redevelopment site is regulated as either solid or hazardous waste and must be managed according to applicable solid or hazardous waste laws, including: • Soil that is characteristically hazardous or contaminated due to a release of a listed hazardous waste, as defined in Minn. R. ch. 7045. Such soil must be managed in accordance with the requirements of the MPCA's Resource Conservation and Recovery Act (RCRA) program. • Waste material such as salvaged bituminous, crushed concrete, bricks, fly ash, etc. proposed to be reused as fill. The beneficial reuse of solid wastes is governed by Minn. R. 7035.2860. Information regarding the beneficial reuse of solid wastes can be found on the MPCA's website at htti3://www.i3ca.state.mn.us/waste/sw-utiIization.htm1. 2. The management and reuse of dredged material may be regulated by permit or subject to other regulations. Information about the management of dredged materials can be found on the MPCA's website at htti3://www.i3ca.state.mn.us/water/dredgedmaterials.htmi. *If sent to a permitted landfill for disposal, unregulated fill may be subject to a solid waste tax. Minnesota Pollution Control Agency 651-296-6300 I 800-657-3864 I TTY 651-282-5332 or 800-657-3864 February 2012 1 c-reml-01 Available in alternative formats AET Project No. P-0025977 Page D 2 of 3 Criteria for unregulated fill Unregulated fill is excess soil that meets all of the following field screening and contaminant concentration criteria: • free from solid waste, debris, asbestos -containing material, visual staining, and chemical odor • organic vapors less than 10 parts per million, as measured by a photoionization detector (PID) • for petroleum -impacted soil, less than 100 mg/kg diesel range organics (DRO)/gasoline range organics (GRO) • for contaminants detected in soil, less than the MPCA's Residential Soil Reference Values (SRVs) and Tier 1 Soil Leaching Values (SLVs)* *Naturally -occurring concentrations of some metals, such as arsenic, selenium, or copper, sometimes exceed the SRV or SLV. Such soils are not considered impacted in the absence of a contaminant source or other field or laboratory indications of contamination. A list of current SRVs can be found in the MPCA's Risk -Based Guidance for the Soil -Human Health Pathway. A list of current SLVs can be found in the Risk -Based Guidance for Evaluating the Soil Leaching Pathway. Both documents can be found at http://www.pca.state.mn.us/cleanup/riskbasedoc.html. For contaminants detected in soil that do not have established SRVs or SLVs, additional evaluation may be needed to determine whether the soil can be considered unregulated fill. Some detections of DRO in soil may stem from the presence of natural organic material or non - petroleum contaminants in the soil, such as coal tars or other material containing polynuclear aromatic hydrocarbons (PAHs). Evaluation of DRO data should take into consideration the history of the property, including the known or likely presence of a petroleum source, the presence (or lack thereof) of other contaminants in the soil sample, and the type of soil. If positive DRO results are related to non - petroleum contaminants, risk -based criteria for the non -petroleum contaminants should be applied. If necessary, laboratory analytical methods are available to help determine if the DRO is from natural organic material in the soil. Placement of unregulated fill To avoid potential problems or public concern stemming from the placement of unregulated fill in sensitive settings, the MPCA recommends the following Best Management Practices: • Avoid placing unregulated fill at schools, playgrounds, daycares, and residential properties. Unregulated fill is most suitable for use at industrial or commercial properties. • Avoid placing unregulated fill in gardens where food for human/animal ingestion will be grown. • Observe a minimum ten -foot separation distance between unregulated fill and the water table. • Avoid placing unregulated fill where contaminants may be transported by run-off to lakes, rivers, wetlands, or streams. Sampling decisions Decisions of whether to sample soil for contamination prior to off -site reuse should be based on the history of the source area, the nature of the source material, the extent to which the soil has been previously characterized, and other factors that are part of a due diligence assessment of the environmental condition of the source property. If the soil originates from a site where known or potential sources of contamination are present, samples of the soil should be collected for field screening and laboratory analyses. Examples of sites where environmental due diligence may reveal known or potential sources of contamination include sites where contamination was previously identified as a result of regulatory action or voluntary Page 2 of 3 1 c-rem1-01 AET Project No. P-0025977 Page D 3 of 3 investigation, previously developed sites (commercial, industrial, recreational, or residential), agricultural properties, or land that may have been subject to dumping, spills, or historic filling activities. If no known or potential sources of contamination are identified during environmental due diligence and subsequent field observations, then sampling of excess soil for laboratory analyses is not necessary. Sample type and frequency When soil sampling is appropriate, the frequency and type of samples should be based on the potential sources of contamination, the depth, volume, and heterogeneity of the source material, and the availability of existing data. At a minimum, analytical parameters should include volatile organic compounds, PAHs, RCRA metals, DRO, and GRO. Other contaminants of concern should be included as appropriate, based on the history of the source location. Analytical data should be age -appropriate and representative of the source material. Some soils even lightly impacted by heavy metals have the potential to leach at concentrations at or above the Toxicity Characteristic Leaching Procedure (TCLP) regulatory limit. As a rule -of -thumb, a TCLP analysis for RCRA metals should be conducted if the soil concentration of a metal is 20 times or greater the TCLP regulatory criteria. A typical frequency for the field screening of potentially contaminated soil using a PID is one measurement for every ten cubic yards of soil. For analytical samples, the stockpile sampling guidance presented in Section 7.3 of the MPCA's Site Characterization and Sampling Document can be used as a frame of reference for the appropriate sampling frequency based on soil volume: http://www.pca.state.mn.us/cleanup/pubs/sitechar.pdf. Soil sampling guidelines for the Petroleum Remediation Program are presented in guidance Document 4-04: http://www.i)ca.state.mn.us/publications/c-i3rp4-04.i3df. Flexibility in the number of samples may be warranted, depending on the site -specific circumstances. Sound professional judgment, taking into account all of the factors discussed above, should be used when developing a sampling plan to determine whether excess soil meets the criteria for unregulated fill. Implementation All parties are encouraged to use the best management practices described herein in order to make good decisions about the off -site reuse of unregulated fill. It is the responsibility of the property owners and other parties engaged in development and construction activities to make sure that their activities include appropriate environmental due diligence and that excess soil and other materials generated by these activities are managed in an environmentally responsible manner. Note that some local units of government, including Dakota County, may have local ordinances which restrict the off -site reuse of unregulated fill within their boundaries. Parties seeking to import unregulated fill should check with local regulators to determine if such ordinances are in effect in their project area. Nothing in this guidance excuses anyone from compliance with any law, rule, or other legal obligation (including any environmental covenant) that applies to any development or construction activity, including the generation, management, transport, and reuse of excess soil.
