environmental review of this project. The ENF review included a public hearing and site visit (bus tour of the Planning Area and the potential wastewater facility sites). Final comments were received and are attached in an appendix in this DCWMP/DEIR. ES.4 SUMMARY OF DETAILED EVALUATIONS TO REMEDIATE THE WASTEWATER PROBLEMS A. Initial Alternatives Evaluation. The alternatives selected for detailed evaluation (as discussed above) were evaluated in detail with cost development and the following findings are noted: 1. The costs for the three alternatives were similar (within 8 percent of one another) due to the large wastewater collection component (sewers and pump stations) that is common to all. The costs for these alternatives are summarized later in this Executive Summary section. 2. The MMR/Otis AFB WWTF site was the best site for the following reasons: It has the most space for a modern expandable treatment facility. It is located in the Planning Area. It does not have any abutting residential neighborhoods; therefore, “Not in my Back Yard” (NIMBY) opposition to this site would be the least of the three sites. It lends itself to becoming a regional facility also serving the towns of Mashpee, Sandwich, and Bourne as well as the MMR; and is consistent with Cape Cod Commission efforts to encourage regionalization where feasible. 3. The Falmouth Country Club site has good infiltration capacity and could recharge a large flow of treated water; however, even with nitrogen removal to 3 mg/L and sewering up to 100% of the watersheds, the return of a large volume of treated water to the watersheds for recharge means that not all of the TMDLs can be met with infiltration at the Falmouth Country Club site as evaluated. These alternatives involving ENR treatment and recharge at the Falmouth Country Club site (Alternatives 1A, 2A and 3A) would meet the Town of Falmouth, MA ES-10 Draft Comprehensive Wastewater Management Plan and Draft Environmental Impact Report 7104510.6
TMDLs for Little, Great, and Green Ponds. However, these alternatives would not meet the TMDL for Bournes Pond or the estimated TMDL for Waquoit West, even with 100% sewering of those watersheds, and even with a Bournes Pond inlet widening. 4. Infiltration at the Falmouth Country Club site would require a large portion of forested area to be cleared to construct the infiltration facilities, and less intrusive recharge technologies are desired. 5. The vast majority of each watershed (100% of some watersheds) needs to be sewered and the wastewater needs to be treated to levels below 3 mg/L total nitrogen and the treated wastewater needs to be recharged fairly evenly across the Planning Area in order to meet TMDLs for all ponds in the planning area. 6. Given the level of treatment required to meet TMDLs, there was a desire to recharge the treated water in such a way that it could be reused to recharge ponds, streams, wetlands, and drinking water supplies. 7. Improved lawn fertilizer management should build on the successful work of the Falmouth Friendly Lawns Program and be promoted and managed by Barnstable County because these problems are common to all Cape towns. 8. The Town has an ongoing stormwater management program managed by the Town’s Engineering Division. This program needs expanded funding to address the many stormwater mitigation needs. 9. The openings to Little Pond and Bournes Pond could be enlarged to provide improved tidal flushing and to reduce wastewater nitrogen removal requirements. Additional evaluation is needed to evaluate environmental impacts and overall feasibility. 10. Watershed modifications are recommended for the Coonamessett River, and the Coonamessett River Restoration Committee moved forward with the recommendation. B. Additional Evaluations for Water Reuse and Well Recharge in the Planning Area.
