/ � r <br /> 2. Wastewater Treatment at Joint Base Cape Cod (JBCC): <br /> a. Potential expansion: <br /> i. Mashpee Subareas H (including High School), L, and M. <br /> ii. Sandwich Subareas Sand-1„ -2, and -3. <br /> iii. No change to open sand beds, <br /> iv. Future consideration (potential WWTF additional expansion): <br /> a) Falmouth areas Fal-13 to Fal-17 (potentially to be recharged outside watershed). <br /> b) No change to open sand beds. <br /> b, Expansion of the existing Carrousel@ WV\/TF to add another parallel train of equal size and an <br /> additional second clarifier. <br /> 3. Wastewater Treatment at Proposed New Facilities: <br /> a. Site 4 to serve Subareas: F, S1, S2, and T: <br /> I. Phased to pick up portions of S adjacent to Falmouth Road first. <br /> ii. Recharge at Site 4. <br /> iii. Fallback recharge area at Willowbend Golf Course. <br /> iv. Treatment performance dependent on recharge location <br /> b. Back Road Site as a backup to JBCC (see 2) <br /> I. Sand-1, Sand-2, and Sand-3 would need to be addressed in their watersheds and <br /> recharged outside the watershed, or possibly connect to a regional facility at Back Road. <br /> c, Site 6 to serve Subareas identified under shellfish propagation (except Subarea B): <br /> I. Later year project as shellfish performance is monitored. <br /> 4.. Wastewater Treatment at Existing WWTFs with Improvements/Expansions/Modifications: <br /> a. New Seabury—expand recharge capacity, potential future expansion of Subarea B (as <br /> fallback to shellfish): <br /> i. Potential expanded recharge capacity from other treatment locations (Mashpee <br /> Commons, Windchime Point and Site 6) drip irrigation in addition to existing recharge <br /> capacity at Site 7 and golf course areas, <br /> ii. No initial expansion needed until new facilities are constructed at Site 6 or modeling <br /> shows shellfish program will not meet. TMDLs with continued recharge from Mashpee <br /> Commons and Windchime Point. <br /> b. Willowbend—expand recharge capacity, as fallback for Site 4 WWTF, improved future <br /> performance to 3 mg/L TN: <br /> i, Potential expanded recharge capacity(drip irrigation). <br /> ii. Potential extension of service to pick up Subarea I. <br /> iii. Evaluate performance needs in conjunction with shellfish results. <br /> c. Mashpee Commons: <br /> i. Potential expansion to Subarea P (and N as required). <br /> ii. Recharge locally Linder shellfish program. <br /> 8612001.4 Town of Mashpee Sewer Commission ES-6 <br /> Final Recommended Plan/Final Environmental Impact Report <br />
