discussed above. The transportation of hazardous materials is regulated at the federal, state and local level. Hazardous materials hauled through this area are reported to the Anoka County Emergency Management Department and are required to be properly placarded, stored and transported according to all applicable regulations. The City of Ramsey Police and Fire Departments are fully trained and prepared for potential derailments. Further information on City preparedness plans can be obtained from Fire Chief Dean Kapler at (763) 427-3764. The Phase I Environmental Assessment performed in June 2002 by Delta Environmental Consultants Inc., concluded, based on site inspection, that hazardous substances and petroleum products were used and stored on an abandoned farmstead along Ramsey Boulevard Northwest within the Town Center site (Figure 19.4). Due to the unsecured nature of these substances, the potential for release or improper disposal exists. Materials identified at the farmstead included cement cans, motor oil containers, an open bucket of motor oil, rust retardant, bonding adhesive, car batteries, antifreeze, air conditioners, refrigerators, and several abandoned vehicles. Tests of ceiling tiles, floor tiles, insulation, and siding from the abandoned farmstead buildings were negative for asbestos. If this site is found to have contaminated soils or groundwater, appropriate remediation will be needed. In order to safeguard and sustain the public water supply, —wellhead protection areas" (WHPAs) and -drinking water supply management areas" (DWSMAs) are delineated around public water supply wells (Figure 20.1). The Ramsey Wellhead Protection Plan was developed in cooperation with Anoka County Environmental Services as part of a ten -city program to delineate WHPAs and identify potential contaminant sources by parcel number. The WHPA is the recharge area for the public water supply. Parameters used to determine recharge area include a ten-year travel time, aquifer transmissivity, pumping volume, flow direction, flow boundaries, and geologic setting. The DWSMA is the geographic area including and adjacent to the WHPA extended to public roads and/or property lines. WHPA and DWSMA designations restrict or specially manage land uses that could degrade the quantity and quality of the public water supply. The most controlled land use in the WHPA is the use of underground storage tanks to store petroleum and any other potentially harmful substance. Underground tanks are allowed in the WHPA if the tanks are double -walled and groundwater around the tank is monitored for contamination from a possible leak in the tank. However, the use of underground tanks in these areas is strongly discouraged. In the case that a leak occurred, alternative water sources, such as the emergency connection with the city of Anoka, would potentially have to be used. Ramsey city wells would be particularly susceptible to an up gradient leak. In the event of a water supply emergency, the City would respond using its normal police and fire emergency response plan until a specific emergency response plan can be developed as part of an updated water supply plan. Summary of Environmental Impact. There is an active MPCA VIC site in the southeast corner of the site as result a release of lead arsenate. The soils and groundwater in that 20-3
