This EBC New Hampshire webinar will provide an overview and update on a new and cutting-edge NPDES General Permit that is likely to be used as model in the future for estuaries receiving effluent from multiple publicly owned treatment works (“POTW”).  The program will focus on the health of the Great Bay Estuary and the Great Bay Total Nitrogen General Permit issued in 2021 by the United States Environmental Protection Agency (“EPA”) in coordination with the New Hampshire Department of Environmental Services (“NH DES”) and 13 POTWs that discharge to Great Bay.    The Total Nitrogen General Permit is the first of its kind in the New England Region and sets important goals for enhancing and restoring the health of the Great Bay Estuary.  This program will: (1) outline the current health of the Great Bay estuary, (2) summarize the complex permitting aspects that regulate discharges into this unique Estuary of National Significance, (3) discuss future State and federal permitting goals for the Estuary, and (4) assess potential impacts that the new regulatory requirements have on local municipalities, industries, and businesses.

The Great Bay Estuary receives treated wastewater effluent containing nitrogen from 17 POTWs located in New Hampshire and Maine.  The estuary also receives a significant nitrogen load from a variety of nonpoint sources and stormwater point sources throughout the watershed. Upon an evaluation of years of ambient monitoring data and other relevant technical and scientific information, EPA determined that the nitrogen load is exceeding the assimilative capacity of the estuary and is causing or contributing, or has the reasonable potential to cause or contribute, to pervasive nutrient-related impairments and violations of water quality standards.  Accordingly, EPA has developed a General Permit for the 13 eligible wastewater treatment facilities, instead of addressing nitrogen loading on a permit-by-permit basis.  The General Permit comprehensively regulates nitrogen on a gross, watershed-wide scale, incorporating an innovative and adaptive approach to achieving water quality standards in the Great Bay estuary through a combination of mandatory load limits at the POTWs and voluntary nonpoint source nitrogen reductions.

During the program, we will learn about the scientific, legal, and regulatory foundations of the General Permit and how it will be implemented.  We will hear different perspectives from the EPA, NH DES, the Conservation Law Foundation, regulated municipalities, and impacted businesses.

A robust panel discussion with the audience will conclude the webinar.

General Continuing Education Certificates are awarded by the EBC for this program (2.0 training contact hours). Certificates are automatically provided via email link for registered attendees at the conclusion of the webinar.
