The 2016 Massachusetts Small MS4 General Permit covering stormwater discharges was signed April 4, 2016 and will become effective on July 1, 2018 at which point the MS4 operator has 90 days to submit a new Notice of Intent (NOI) to EPA in order to obtain authorization to discharge. 

CEI has created a number of resources to assist municipalities including general permit information, expected permit costs, funding options and specifics on the Performance Action Items (PAIs).
