GIS Requirements for WSC Forms

MassDEP requires Latitude and Longitude (Lat/Long) coordinates on the Release Notification Form (BWSC103 and BWSC103 120 Day), the Tier  Classification Form (BWSC107), and the Permanent and Temporary Solution Statement (BWSC 104). 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
