GIS Requirements for WSC Forms

MassDEP requires Latitude and Longitude (Lat/Long) coordinates on the Release Notification Form (BWSC103 and BWSC103 120Day) and the Tier  Classification Form (BWSC107). Other BWSC forms may have an optional section for Lat/Long. Lat/Long lookups are available through when the form is filed. See instructions for Using the GIS Location Finder below. Alternatively, the Lat/Long coordinates for a release location may be determined by using the MassGIS Color Ortho Imagery Viewer.

This function allows you to get Lat/Long Coordinates for your site by marking the location directly on an aerial map
