16 Great Neck Road North <br />Nashpee, 9vlassachusetts 02649 <br />Gabrielle Belfit and Jessica Cajigas are present tonight on behalf of Tighe & Bond. Currently, <br />Mashpee is on permit year 5 of the stormwater permit. Stormwater is the fastest growing type <br />of pollution in Massachusetts. They are here to address a federal permit that deals with <br />stormwater pollution from municipally owned areas. These areas include streets, lawns, <br />parking lots, and sidewalks polluted by trash, oil, sediments, fertilizers, and bacteria. These <br />areas become polluted as water moves over surfaces and proceeds to groundwater as well as <br />larger bodies of water. The more impervious a surface, the more stormwater runoff is <br />generated and has a greater impact. <br />EPA regulated stormwater is regulated by MS4, which is the municipal storm water system <br />program. This is administered jointly by the EPA and Mass DEP. The MS4 Mashpee area <br />includes all drainage within the urbanized area, but is only covered by municipally owned <br />roads. They are not dealing with anything private in the MS4 zone. <br />Coverage of this permit began in 2019 and expired this past summer of June 2022. It has been <br />administratively continued as declared by EPA, and it will continue for the next 5 years for <br />compliance purposes. Permit years align with the fiscal start within the municipality. <br />This program acts as the document that dictates Mashpee's requirements within the permit. It <br />is set up to address six minimum control measures: public education and outreach, public <br />involvement and participation, IDDE program, construction site sormwater runoff, stormwater <br />management with new development, as well as good housekeeping practices for pollution <br />prevention. <br />Addressing the six measures includes specific plans and updates to regulations that have <br />been created and adopted over the past four years. Right now the focus is on water bodies <br />within the Town of Mashpee that have total max daily loads or are identified as impaired water <br />bodies. In looking at the map, impaired water bodies are in red, and these are Santuit Pond, <br />Ashumet Pond, and Mashpee Pond. Remaining water bodies shown on the map in yellow <br />represent nitrogen or bacteria affected areas. Mercury is found in several water bodies but <br />there is no permit regulations for mercury. These impairments have to meet certain <br />requirements amongst the six pillars. Annual timely messages alert citizens for education <br />purposes, best management practices for construction and new development are used to <br />optimize for nitrogen and phosphorus removal, as well as continuous street sweeping. <br />Ms. Waygan knows this is a permit that is granted to the town, as they were here a couple <br />years ago. She is unclear what parts of Mashpee this permit is applied. She inquired about <br />privately owned residential and commercial properties. She was informed that the town will not <br />implement these requirements for best management on private properties. <br />OJ <br />
