Abstract

Although this document was not produced by PREP, it is being listed with the permission of the Conservation Law Foundation here due to its importance to PREP’s mission, which is to protect the Great Bay and Hampton-Seabrook Estuaries. This report was developed by Waterstone Engineering, PLLC, and prepared for the Conservation Law Foundation.

The intent of this report is to determine the feasibility and cost for regulated communities in the Great Bay watershed to implement the optional non-point source and stormwater point source nitrogen pathway outlined in EPA’s draft Greay Bay Total Nitrogen General Permit. Feasibility was evaluated for a community’s ability to reduce non-point source and stormwater-derived nitrogen by 45% over four 5-year permit periods. This study represents one scenario of many possible pathways and encourages communities to implement innovative nutrient control strategies including a combination of non-structural and low-cost best management practices in addition to more conventional strategies in order to achieve reduction targets.
