The start of a new year is a good time to look at how environmental regulations have been updated... and how these updates impact real estate development.
New requirements for the Wetland Protection Act's (WPA) Regulations 310 CMR 10.00 went into effect on October 24, 2014. The updates added exemptions for buffer zone activities for certain highway and utility work; added a renewable energy limited project; clarified that new stormwater facilities do not create wetland resources areas; streamlined permitting by allowing for a combined application for projects that fall under the WPA, Chapter 91, and 401 Water Quality Certification; created a general permit for ecological restoration projects; updated stream crossing standards; and simplified permitting for short-term tests of innovative technologies.
Chapter 91 Waterways regulations were updated to streamline the process for projects that also require permits under the Massachusetts Environmental Policy Act (MEPA) and WPA, and simplify the process for small docks (<600 s/f for coastal and <300 s/f for inland) by adding a general license.
While the first two regulation updates don't have a significant impact on the development community, the small Municipal Separate Storm Sewer Systems (MS4) General Permit may be a different story. The update is currently underway, with the public comment period ending December 29, 2014. The Environmental Protection Agency (EPA) has issued a single draft permit for all of Massachusetts, which combines the previous North Coastal and Interstate, Merrimack, and South Coastal permits. Under the MS4 permit, cities and towns are responsible for compliance; however, they will do so by creating bylaws/ordinances and regulations that directly impact development projects.
The Draft MS4 includes the same six minimum control measures as the 2003 MS4 Permit (public education and outreach, public participation, illicit discharge detection and elimination, construction site runoff control, post-construction runoff control, pollution prevention/good housekeeping), but the Draft MS4 includes additional water quality standards:
* Enhanced illicit discharge detection and elimination (IDDE) requirements to identify, isolate, and remove sanitary and other wastes from the stormwater system;
* Water quality monitoring of stormwater discharges;
* Encouragement of low impact development and green infrastructure techniques; and
* Requirements designed to implement approved total maximum daily load (TMDL) waste load allocations (WLAs).
Requirements for IDDE and water quality monitoring place a financial burden on cities and towns already strapped for money; this may end up trickling down to developers. At a recent EPA and DEP public hearing in Leominster for the Draft MS4, several municipalities expressed concern and requested clarification on these requirements and exemptions.
One new water quality requirement specifies controlling and treating the first inch of runoff for new and redevelopment projects. This requirement is different than the current DEP Stormwater Standards under the WPA Regulations, and most towns' and cities' local requirements. Historically, DEP and EPA have coordinated permits, which may not happen with the new MS4, leaving a disconnect between State permits and the EPA stormwater requirements.
Another question about the Draft MS4 is how controlling the first inch of runoff will be applied across redevelopment sites. For example, if you are working on a small portion of a large site, will the entire site be required to be retrofitted to treat and control the first inch of runoff? There were several comments requesting clarification on this during the MS4 Public Hearing. We will monitor the responses to comments and track what changes/clarifications are made to the Draft MS4, which is scheduled to be issued Fall 2015.
