The Project consists of a 369-acre mixed -use development. Regarding matters for which the Minnesota Pollution Control Agency (MPCA) has regulatory responsibility or other interests, the MPCA staff has the following comments for your consideration. Soil and Groundwater Contamination (item 19) The AUAR Update indicates that contaminants were discovered on site 47 in the soil and soil gas at concentrations above established regulatory thresholds. Due to the potential for soil vapor migration and the presence of a residential development on the eastern third of this site, the MPCA recommends the City conduct an investigation to determine the extent and magnitude of the contamination on site 47 in the immediate future, rather than waiting until there is a proposed development as stated in the AUAR Update. Assistance is available from the MPCA's Brownfields Program to receive necessary technical assistance in managing contamination. For some properties, special construction might be needed to prevent the further spreading of the contamination and/or prevent vapors from entering buildings or utility corridors. Information regarding the Brownfields Program can be found at: https://www.pca.state.mn.us/waste/brownfields. Please note that contamination that is found must be reported immediately to the state duty officer at 651-649-5451 or 800-422-0798. Dust, Odors, Noise (Item 24) This development will be subject to the state noise standards. Item 24 of the AUAR Update refers to dust, odors, and noise. Item 24.1 refers back to potential noise mitigation techniques for Blocks 28, 26, 37, and 38. Without being able to reference earlier maps and plans, the assumption is that these Blocks are the residential areas south of Bunker Lake Blvd in the Residential development area now labeled COR-4B.
