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 first part of 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 and has been completed and approved by the Minnesota Department of Health (MDH). This half of the wellhead protection plan addresses WHPAs, DWSMAs and well vulnerability classifications. Parameters used to determine the WHPA include a ten-year groundwater 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. The second part of the City's wellhead protection plan is currently in progress and will address contaminant sources and education initiatives within the site and the City WHPA/DWSMA. WHPA and DWSMA designations restrict or specially manage land uses that could degrade the quantity and quality of the public water supply. For example, the use of underground storage tanks to store petroleum and any other potentially harmful substance within a WHPA is not recommended by MDH. Underground tanks are allowed, in general, within WHPAs if the tanks are double -walled and groundwater around the tank is monitored for contamination from a possible leak in the tank. However, because the process of wellhead protection is specific and tailored to land use conditions within each WHPA/DWSMA, the development of the City's wellhead protection plan and priority of contaminants will be determined by the City and MDH. In case a leak occurred, and alternative water sources were required there is an emergency water supply connection with the city of Anoka. In the event of a water supply emergency, the City will respond 20-3
