Re: Search for public or private water supplies at Maine Voluntary Response Action Program (VRAP) sites
This memorandum clarifies what constitutes a sufficient effort to determine if public or private water supplies are within 2500 feet of a VRAP site.
Given that VRAP sites can be both hazardous materials and petroleum, 2500 feet was chosen as an appropriate radius (and not the radius prescribed in the petroleum guidance). If you have an area that is not serviced by public water, we will assume that all the properties have private water supplies and you need only supply the location of the closest water supply in each direction from the site (i.e. no pre-determined radius requirement).
For all other sites that are apparently serviced by public water supplies, the first course of action should be to inquire about the service area for the water company, insuring that all areas within a 2500 foot radius are serviced with waterlines, and that the source of the public water is not located within 2500 feet of the site. Secondly, water company personnel should be asked if they know of any private wells or properties that are not connected within the prescribed radius. Ultimately, you will also need to ensure that all the properties (as defined on a municipal tax map) with structures are being billed by the water company. Any public or private wells identified during the survey should be identified on a map accurately depicting the location of these wells in relationship to the subject site.
If a site is located in close proximity to a major surface water body, the radius does not need to extend in that direction. Brooks, streams and farm ponds are not considered “major surface water bodies” for the purposes of this guidance.
Well survey materials collected during the investigation of nearby VRAP sites is also acceptable as part of the submission. Our intent is not to “reinvent the wheel” when perfectly good information is readily available. If well survey material is greater than three years old, however, it should not be relied upon in meeting this application submission requirement.
