page 14 12. Contamination/Hazardous Materials/Wastes: a. Pre-project site conditions - Describe existing contamination or potential environmental hazards on or in close proximity to the project site such as soil or ground water contamination, abandoned dumps, closed landfills, existing or abandoned storage tanks, and hazardous liquid or gas pipelines. Discuss any potential environmental effects from pre-project site conditions that would be caused or exacerbated by project construction and operation. Identify measures to avoid, minimize or mitigate adverse effects from existing contamination or potential environmental hazards. Include development of a Contingency Plan or Response Action Plan. The project area was reviewed for potentially contaminated soils using publically-available data. The following databases were reviewed:  MPCA “What’s in My Neighborhood?” website and  MPCA Tanks and Leaks website  Minnesota Department of Agriculture (MDA) “What’s in My Neighborhood?” website  Phase I Environmental Site Assessment (ESA)  Phase II ESA One MPCA database listing was identified within the project area for an underground storage tank (UST) and leak (Figure 14, Site 1). The UST, 12,000 gallons in size, contained fuel oil, and was removed in 1986. The location of the removed UST tank is unknown at this time. The associated site leak was discovered in 2012, consisted of fuel oil 1 & 2, impacted groundwater, and was issued site closure by the MPCA on March 15, 2013. Site closure means that an investigation has been completed and the MPCA has determined the leak does not pose a threat to human health or the environment in its current state. Site closure does not mean that the site is free of contamination. Four MPCA database listings were identified immediately adjacent to the project area. One of these four listings, Site 2, contained evidence of contamination. Site 2 is listed on the Leaks database. The identified leak (ID 407) was discovered in 1987, consisted of fuel oil 1 & 2 and leaded gasoline, and was issued site closure by the MPCA on November 26, 1991. Due to the proximity of this site, it is possible the leak has resulted in contamination within the eastern portion of the project area. In addition to the MPCA data, there have been a number of pervious environmental documents prepared for the project area. Phase I and II ESAs were completed for the project area in 2012, and two additional Phase II investigations were completed in 2016. The Phase I ESA identified two recognized environmental conditions (RECs) associated with the project area. REC-1 was the result of two historical dry cleaners located adjacent to the project area to the southwest. REC-2 was the result of two former fuel oil USTs, which were removed from the project area near the laundry/shower room building in 2012. Previous investigations determined that at least one of the two USTs had leaked, resulting in soil and groundwater impacts. The associated MPCA leak number (ID 18847) was issued site closure in 2013. In 2016, diesel range organics (DRO) were detected at a maximum concentration of 364 milligrams per kilogram (mg/kg) in the soil at the project area which is above the MPCA’s criteria for unregulated fill of 100 mg/kg. Various volatile organic compounds (VOCs) were also 49
