GIS Requirements for WSC Forms

MassDEP requires Universal Transverse Mercator (UTM) coordinates on the Release Notification Form (BWSC103 and BWSC120Day) and the Numerical Ranking Scoresheet (BWSC107A). Other BWSC forms may have an optional section for UTMs. UTM lookups are available through when the form is filed. See instructions for Using the GIS Location Finder below. Alternatively, the UTM coordinates for a release location may be determined by using the MassGIS Color Ortho Imagery Viewer.

This  function allows you to get UTMs  for your site by marking the location directly on an aerial map
