of TMs s,s <br /> z. <br /> AU�1MLIUV��y <br /> own qf MaS 2 Panning Board <br /> c� <br /> 16 Great Weck RoadWorth <br /> -Mashpee, -Massachusetts 02649 <br /> as well. Right now they are only looking at what needs to be completed to reach compliance <br /> with the general permit.Addressing the design of the system for nitrogen, phosphorous, and <br /> total suspended solids. How they are addressed is through engineering design, and certain <br /> types of systems have different operating procedures. EPA is stating you need to retain one <br /> inch of runoff and remove 90% of total suspended solids on new construction. For <br /> redevelopment, the nitrogen and phosphorus retention is .68 inches with 80% removal of total <br /> suspended solids. <br /> Low impact design will be utilized unless infeasible. Ms. Waygan inquired what constitutes LID, <br /> that is left for the Board to decide. Mr. Tobin would like all that wording in red ink to say "utilizes <br /> LID site planning and development strategies". <br /> Ms. Waygan asked if best management practices (BMP)was defined somewhere. <br /> Nitrogen appears in appendices specific to nutrient impairments, Appendix F and G, if it <br /> removes nitrogen, it removes phosphorous. The nutrient reduction percentages are the same, <br /> 60% of phosphorous, but that will be clarified. <br /> Ms. Faulkner asked about the phosphorous load reduction before this, and it did not change. <br /> Activities exclusively related to improvements and maintenance to existing roadways include <br /> paving or widening greater than or equal to a single lane, anything less than single lane would <br /> be exempt. <br /> MOTION: <br /> Mr. Balzarini made a motion to approve the Town Planner and Consultant finalize <br /> the Stormwater Management Amendment for submission to the Select Board, on <br /> behalf of the Planning Board, and a Public Hearing to be held after submission to <br /> Select Board. Seconded by Ms. Faulkner.All in favor. <br /> Ms. Belfit will forward a draft to the EPA for their review. The document will also be submitted <br /> to Town Counsel for input.
