M <br /> The 1990 buildout (total amount to be built in the area) will <br /> double concentrations. <br /> What can you do about it? As of February 1991 DEP reviewed a <br /> pilot project and tentatively approved on a case by case basis <br /> the 'use of residential RUCK systems . The systems are installed <br /> in the pine barrens of New Jersey and required in critical <br /> coastal areas of Rhode Island. <br /> Santuit is complicated because you must deal with the Town- of <br /> Barnstable but Mashpee does have control over 3/4 of the nitrogen <br /> loading. <br /> All of the nitrogen is going to be put in the ground through <br /> individual or combined systems. In many areas in Santuit region <br /> the buildout has not occurred yet, the lots are just on paper. <br /> If it is necessary to reduce nitrogen, RUCK systems -remove -an <br /> average of 80% of nitrogen. If the Town required they be put in <br /> place in a new home they could significantly reduce total <br /> nitrogen load. <br /> In an area of total build out they would have to retrofit. <br /> Judy asked the cost of this system <br /> Dr. -Kerfoot stated it would range from $5, 000 to $10, 000. The <br /> higher cost is when the system has to be elevated. Relative to <br /> the cost of Waterfront homes it is not a great cost. <br /> Pat asked how much more land these systems require? <br /> Dr. Kerfoot stated about twice the amount of a typical system. <br /> Tony stated that in certain cases (Pilgrims Pride Nursing Home) <br /> it may be cost effective because of the amount of the <br /> contribution. <br /> Runoff situations - crossing between Route 2$ and the 130 <br /> connections generate a good deal -of runoff. General <br /> recommendations are no direct discharges into the River systems . <br /> Consistency with CZM plans in resurfacing of State Highways could <br /> be leverage. It is cost effective to have catch basins replaced <br /> at the time of resurfacing. <br /> Plastic galleys with filter systems built in now available cost <br /> less than the concrete. <br /> Nutrient transport - die off of leaves and organic debris which <br /> goes into river system every fall and then gets pushed <br /> downstream. The nutrient content from septic systems is focused <br /> in narrow area of the bank and it becomes a very hydroponic area, <br /> great for growing vegetation, accelerated growth. <br /> In areas of the Mashpee River, growth has reduced the channel to <br /> a very limited one. It is better to have the bank of the river <br /> cleared. <br /> 7 <br />
