Attached is the proposed bylaw required to comply with this control measure. Background Through the NPDES program,the EPA nationally regulates the discharge of stormwater runoff that is transported into local water bodies. Mashpee, as a small MS4, had to file a General Permit in 2003.This permit expired in 2008 but remained in effect until new regulations were issued by EPA in 2017. The reissued NPDES General Permit for Stormwater Discharges substantially increased stormwater management requirements and mandates specific timelines for compliance. Notices of intent for the new Permit had to be submitted by October 1, 2018. The purpose of the proposed bylaw is to explicitly prohibit contaminants from being released and/or entering the Town's stormwater system and ultimately into the Town's surface and ground waters. The bylaw also establishes an enforcement method for ensuring elimination of any illicit discharges found. Adoption of this bylaw is a requirement of the Town's General Storm Water Permit submitted to the EPA. The proposed bylaw is a model bylaw that has already been approved by the MA Attorney General's Office for other municipalities. Recommendation I recommend that an article be placed on the October 2019 Annual Town Meeting for adoption of the proposed Illicit Connections and Discharges to the-Municipal Storm Drain System General Bylaw, Pros and Cons Failure to adopt the proposed bylaw would be a violation of the Town's General Permit.
