13 houses which existed prior to the regulations are close to the lake. Correspondence which has been received from affected property owners is attached. The proposed amendment is summarized as follows: 1) Wells would be allowed in stream buffers; and 2) Nitrification fields would continue to be located 300 feet from reservoirs and outside of stream buffers. Septic tanks and pumps could be located 150 feet from the reservoir or outside of the stream buffer. (The setback for structures is only 150 feet. It is often necessary or preferable to locate the tank in close proximity to the residence. ) ; and 3 ) Existing development would be deemed conforming with respect to watershed standards; and 4 ) If destroyed, existing structures could be replaced in their current location provided that there is no increase in impervious surface and no increase in any existing encroachment into buffers or setbacks. 5) Setbacks and buffers for development on pre-existing lots could be reduced if all of the following criteria were met: a) The septic system is sized for no more than four bedrooms; and b) septic area and repair can be accommodated on 20,000 square feet or less; and c) encroachment into setbacks is necessary in order to build on the lot; and d) the relative location of the well, septic system and structure maximizes the degree of watershed protection which can be obtained while allowing development of the lot; and e) the amount of encroachment is the minimum that can be obtained while meeting the above criteria; and f) there are no existing water quality problems caused by malfunctioning septic systems within 300 feet of the reservoir. -6) The requirement that the Environmental Management Commission (EMC) approve major exemptions, as required by the State mandate, is clarified. EMC approval of a variance is required only if reduction exceeds 10% of the State minimum. Y 4
