i r co Scenario Fair Share reduction. co Scenario 5—Centralized treatment approach.

The findings were used in the development of options 1A, 1B, andC as, outlined in the 2012 Technical Memorandum presenting those options for addressing nitrogen in the watersheds. The ultimate goal of those new options was to advance the development of a Recommended Flan for nitrogen management within the FTA. Each option was modeled by the MEP to demonstrate feasibility to moot the T IDLs The results of those model runs were formally presented in the Final AFAR. The 2013 ASAR summarized the planning efforts performed to date, the model results and findings for the three proposed options I A, 1 B, and 1 Com), and the technologies screened as part of the 2007 Technology Screening Deport). This document also summarized the framework for the Recommended Plan and identified the general categories of nitrogen removal that would be used to form the basis of the Recommended Felon. The ASAI.identified these main categories to address nitrogen r+emovel. 00 Source removal. Go Direct Environmental Mitigation. 00 Land management Strategies. Using these categories the ASAR outlined a framework for the development of the Recommended Plan,. The 2014 Draft recommended Flan built upon this effort and evaluated alternatives to the option I A plan, including: 00 Centralized vs.. new cluster area treatment facilities co Regional Solutions co Existing Wastewater Treatment Facilities WWTFs co Traditional vs, Hybrid Solutions — Primarily.- o Shellfish Aquaculture — Secondarily: Permeable reactive Barrier,(PRB) Bog and Wetland restoration Onsite systems The evaluations and draft recommended plain are included in Chapters 4 and 5 of this report. 86120 1.4 Town of Mashpee Seaver Commission ES-4 .
