A map showing <br />the Project Area is included as Figure 1. The following online databases were reviewed on <br />January 30, 2020 as part of this desktop environmental review: <br /> <br />• Minnesota Pollution Control Agency (MPCA) "What's in My Neighborhood?" website <br />• Minnesota Department of Agriculture (MDA) "What's in My Neighborhood?" website <br /> <br />This desktop contamination review is not intended to replace a Phase I Environmental Site <br />Assessment (ESA) performed per ASTM E1527-13. WSB did not verify the database information <br />for accuracy. Therefore, further environmental review is recommended prior to performing any <br />follow-up investigation work (e.g. subsurface borings) to verify WIMN source information. Based <br />on this desktop review, the following information is provided: <br /> <br />Project Area Sites <br />Thirty-three (33) sites were identified at the Project Area (see Figures 2, 2A, and 2B). The sites <br />are associated with 50 database listings, summarized below: <br /> <br />• Twenty-one (21) stormwater permit listings (18 construction and 3 industrial); <br />• Fifteen (15) hazardous waste generator listings. Inclusion on the hazardous waste <br />generator database indicates the site generates hazardous waste requiring a permit; <br />• Five (5) listings were for sites with aboveground tanks (AST) and/or underground <br />tanks (USTs) but do not directly indicate a petroleum spill or release; <br />• Two (2) air quality permit listings; and <br />• One (1) site assessment listing. Site Assessment sites are places where <br />contamination or regulated waste activities have been reported to the MPCA. If it is <br />determined that little or no exposure potential exists and no further remedial actions <br />are planned, the site is closed and listed as inactive. <br /> <br />None of the identified Project Area listings indicate a hazardous material spill or release except <br />for the following six (6) listings: <br />
