Phase II of the EPA’s Storm Water Regulation expands the Phase I program by requiring additional operators of MS4s in urbanized areas and operators of small construction sites, through the use of NPDES permits, to implement programs and practices to control polluted stormwater runoff. Phase II is intended to further reduce adverse impacts to water quality and aquatic habitat by instituting the use of controls on the unregulated sources of stormwater discharges that have the greatest likelihood of causing continued environmental degradation.
Permit Program Background
On May 1, 2003, EPA Region 1 issued its Final General Permit for Stormwater Discharges from Small Municipal Separate Storm Sewer Systems (2003 small MS4 permit) consistent with the Phase II rule. The 2003 small MS4 permit covered “traditional” (i.e., cities and towns) and “non-traditional” (i.e., Federal and state agencies) MS4 Operators located in the states of Massachusetts and New Hampshire. This permit expired on May 1, 2008 but remained in effect until operators were authorized under the 2016 MS4 general permit, which became effective on July 1, 2018. As of 2019, the Town of Windham Stormwater Committee has drafted an Illicit Discharge Detection and Elimination (IDDE) Plan to comply with the National Pollutant Discharge Elimination System (NPDES) permit. This includes locating and mapping out the location of all outfalls and catch basins within the Town of Windham. The Committee has also worked to educate the public on stormwater regulations by providing residence with information on well water, septic systems, and pet waste. We urge Windham residents to become involved and take personal steps to reduce and police runoff contamination within their property and the community.
Stormwater Management Program (SWMP)
The SWMP describes and details the activities and measures that will be implemented to meet the terms and conditions of the permit. The document will be updated and/or modified during the permit term as the Town’s activities are modified, changed or updated to meet permit conditions during the permit term. The main elements or Best Management Practices (BMP) of the stormwater management program are:
- A public education program in order to affect public behavior causing stormwater pollution.
- An opportunity for the public to participate and provide comments on the stormwater program.
- A program to site stormwater discharges to the MS4.
- A program to effectively control construction site stormwater discharges to the MS4.
- A program to ensure that stormwater from development projects entering the MS4 is adequately controlled by the construction of stormwater controls.
- A good housekeeping program to ensure that stormwater pollution sources on municipal properties and from municipal operations are minimized.
