Soils Management Procedure

Soils Management includes procedures for removal of contaminated soil from the MSP, site storage of contaminated soil at the MSP, assistance with utilizing contaminated soil at the MSP, and verification of existing soils. 

Requirements for Project Soils Management and Dewatering: 

Design Consultant or Tenant shall incorporate specific requirements into specifications for soil management specifically for the disposal of contaminated soils. 

Submittals

1. If project qualifies for the Petrofund, contractor to submit all appropriate documentation in a timely manner in accordance with the Petrofund requirements which can be found here: Petrofund / Minnesota Department of Commerce - Business (mn.gov) 

Contractor responsible to follow MAC’s Soil Management Plan to applicable criteria as well. Contact MAC Environmental Affairs for access to this document.  

Schedule: The Contractor shall submit a schedule indicating proposed methods and sequence of operations for construction dewatering work to Engineer and Owner’s Representative for review ten (10) working days prior to commencement of the Work. 

Provide detailed sequence of construction work to ensure uninterrupted progress of Owner’s on- site operations. 

Disposal Plan for Removal and Waste Management. Include the requirements for the Contractor to submit a Disposal Plan prior to beginning work on the site. Plan to include the following: 

1. Identification of Project Site: General site history (i.e., known areas of soil contamination from UST releases, fueling areas, dumping, or no known history that would suggest soil impacts). 

2. Minnesota Department of Commerce (MDC) Petrofund Board Contractor Registration Number.

3. MnDOT hazardous waste transporter license number for hauler transporting petroleum product. 

4. Description of the testing program to identify impacted soil and bedrock so that Contractor can make arrangements for proper off-site treatment and disposal. Soil sample and other work is required to be completed to assist in obtaining disposal permits by characterizing impacts in the soil. 

5. Name, location, MPCA Certification Form(s), and permit(s) of MPCA-approved site and any other required permit from local, county or other regulatory agencies for disposal of all impacted soil, bedrock, and caisson cuttings. Finalize prior to any off-site disposal. 

6. Name, location, permit(s) and approvals of sites for disposal of all unimpacted soil, bedrock, and caisson cuttings. On-site testing may be required for unimpacted soils. Consult with disposal site for requirements. Where certification of unimpacted soil is required, Contractor to provide on-site testing and provide test report to disposal facility. 

7. Description of the sediment removal equipment and/or system to be used for removing suspended and settleable solids from the construction dewatering water prior to discharge to the sanitary sewer system. A list of pumps and other equipment that will be used for dewatering and dewatering water sediment removal. 

8. Field Screening: Ongoing assessment of soils that are excavated (for verification of impacted or non-impacted) identify how often (based on per volume, hours, day whatever); what instrumentation will be used, by who, calibration, reporting, documentation. 

9. Contingencies: Actions to be taken if unexpected environmental conditions are encountered such as piping, asbestos (or potential asbestos containing items), tanks, drums, etc. Identify contacts, cleaning/liquid removal, temporary storage on-site if needed, management and disposal processes and approvals. 

The Contractor shall maintain the hazardous waste manifests for three years after completion of work: 

1. All applicable Hazardous or Special Waste Manifest(s) for transport of petroleum product or other hazardous liquids or special wastes from the project site to the licensed hazardous waste or special waste disposal facility. 

2. Manifests for disposal of non-hazardous materials from the project site and the name of product recycler (if applicable). 

3. Manifests and/or receipts for disposal and treatment of impacted soil and bedrock, including the name and location of the disposal and treatment site. 

4. Documentation confirming treatment of impacted soil and bedrock. 

5. Documentation indicating final use of the treated soil and bedrock. 

6. Manifests and/or receipts for disposal of unimpacted soil and bedrock, including the name and location of the disposal site. 

7. Documentation indicating the final use of the unimpacted soil and bedrock. 

Design Consultant or Tenant shall meet with MAC Environmental Consultant, Inc. if preliminary soils reports indicate potential contaminated soils or ground water. 

MAC Environmental Consultant will develop requirements for soils and dewatering operations specific to the Projects.
