V. ADDITIONAL CONTAMINATION INFORMATION – CLEANUP APPLICANTS ONLY For applicants requesting assistance for cleanup, completed the following additional questions: 1. Provide a concise description of the proposed RAP and/or asbestos, lead-based paint abatement. Limit your response to 300 words. Include the following additional details: The following response actions as proposed in the RAP are proposed for the development: • Demolition of the existing structure; • Exaction, monitoring, and management of soil generated by Site development grading activities; • Potential dewatering of impacted perched water; and • Documentation of; through limited sidewall and excavation bottom sampling, soil conditions of soil exhibiting evidence of impacts that is targeted to be left in place below the readily accessible zone or in areas deemed inaccessible due to construction of Site improvements. The MPCA approved the RAP/CCP by letter dated October 26, 2022. One of the conditions of the approval relates to the previous location of the dry-cleaning facility. It is presumed that portion of the soil in former dry cleaner location (northeast corner of the Property) will need to be managed as regulated fill and disposed of properly at a landfill. The MPCA approval states that while off-site disposal of some of the soil removed from the area is likely appropriate, the necessity to do so would be better supported by adequate soil sampling to assess the release of hazardous substances from the historical drycleaner operation. As such, Stantec will complete additional soil sampling in the vicinity of the dry cleaner to assist in guiding the response actions during the redevelopment. I. If demolition is part of your funding request, describe demolition activities necessary to perform the cleanup, including age, condition of structures and required asbestos and/or lead paint abatement. Demolition is only eligible when it is required for cleanup activities as part of the RAP; demolition for general construction and redevelopment purposes is not eligible. Demolition costs are not being requested. II. Describe efforts to reuse contaminated soils on site. If soil is not being reused, why is this not feasible? Soils deemed suitable for unrestricted reuse (analytical resting below MPCA Residential SRVs and SLVs, DRO and/or GRO less than 100 mg/kg, headspace PID field screening below 10 parts per million [ppm], and free of debris, stain, and odors) will be beneficially reused as backfill on the Property or within the accessible zone. Excavated soils with analytical testing results below MPCA Industrial SRVs and/or MPCA SLVs, DRO/GRO below 100 mg/kg, PID field screening between 10 ppm and 50 ppm, and no visual debris, ash, or other signs of impacted fill will be beneficially reused in areas not within the accessible zone at the Property as geotechnically appropriate.
