Gateway Business Center - Arden Hills. MN September 2001 EAW and 1-35W interchanges, The Gateway Business district allows for flexibility and a mix of business, multi-family residential, and office development. The City requires that the . mix, relationship and intensity of uses and huildings be compatible and complementary with uses in the district and adjacent uses. Potential Conflicts Involving Environmental Matters According to the Phase I Environmental Assessment (EA), January 4, 2001, a rendering plant was located just north of the site for many years, The City of Arden Hills took control of this property around 1990 and a limited environmental investigation was completed to assess potential impacts from the plant. No significant soil or groundwater impacts were identified at the plant that would be expected to impact the site, An abandoned railroad spur line that served the rendering plant remains adjaeent to portions of the northern houndary of the site, Three or four large circular structures were located adjacent to the north of the site in the 1950's, at the current location of the ATS Steel building. The use of these structures is unknown, but they eould have been storage tanks, holding pens or impoundments associated with the rendering plant. No information about these structures was found. The ATS Steel building is currently used for warehousing and steel manufacturing, Hazardous wastes generated at the facility over the past ten years include waste paint, used oil and filters and degreasing solvents, According to the Phase I Environmental Assessment, review of the Ramsey County hazardous waste inspeetion file for the ATS site identified no hazardous waste storage or disposal problems or violations. Based on the past presence of the circular structures and history of hazardous waste generation at the A TS Steel facility, a potential for soil or groundwater contamination exists, especially since the property is adjacent to and located at an upgradient location. Buried items were reportedly eneountered on the site during redevelopment of the ATS property, No information about these items was available. Two groundwater monitoring wells are present on the northwest portion of the site, These wells are part of a large groundwater monitoring network associated with the former Twin Cities Army Ammunition Plan (TCAAP), located approximately three-quarters of a mile to the northeast of the site. The wells were completed in two separate aquifers. Review of analytical data related to collected water samples indicates groundwater on the western edge of the site was impacted with volatile organic compounds (VOCs), However, contamination has not been detected in these wells for several years. A groundwater pump and treatment system continues to operate at the TCAAP facility to remediate eontaminated groundwater, and contains the contamination plumes that extend beyond the borders of the TCAAP facility, Debris and other items found on the ground surface during a site visit included discarded metal piping and other metal equipment, brush, furniture, wood pallets, a small abandoned camping trailer, a wooden feed dispenser, plastic water and feed containers and discarded canvas signs, A small quantity of insulated wallboard with a tarpaper layer Page 8 e .
