Raul Lizardi-Rivera,from Cape and Islands Engineering, introduced himself for the record,stating that the project is for a second upgrade to the system at this dwelling. The original cesspool was deemed to be in failure in 1993. A Title V inspection for property transfer showed the leaching within 18"of groundwater. A leaching system that provides 4' separation to groundwater is being proposed for the same location. The plan also proposes to keep it as a bed system, and to raise the grade slightly so the driveway remains functional. Mr. Harrington stated that the dwelling is reported to be a legal two-family. The question is whether or not the existence of the two-family requires a second compartment tank, or whether the one tank septic system with the two-family dwelling would be grandfathered based on the prior approval. There is a letter in Building Department files that indicates the property was approved to be developed as a two- family. The environmental code at the time did not require a two-compartment tank. Mr. Harrington reminded the board that,when approving a variance to groundwater, board members can set conditions and, in this case,the condition can be the addition of a 1000 gallon septic tank as a second compartment prior to the pump chamber. Matthew Costa, of Cape & Islands Engineering, stated that the property is a legal two family, and there is a Certificate of Compliance on the old system,effectively approving the tank for the multi-family dwelling, as well as a new inspection that did not fail the tank. Mr. Costa felt there was no mechanism tripping the upgrade of tank, stressing to the board that it was entirely at their discretion, and that a second tank would be an additional expense for property owner. Chair Baumgaertel stated that, regardless of the history of the property, the board has to give consideration to the fact that it is a two family, which requires a two compartment or tanks in series. Mr. Costa then requested that the second compartment be a condition of approval, and stated he would be submitting revised plans immediately, as there is a closing scheduled on the property at the end of the month. There was a brief discussion about thrust blocking and everyone agreed that it would not to be necessary at this location due to size of pump. At Mr. Costa's request, approval would be for a two-compartment tank that will meet the requirements for 100%capacity with 24-hours reserve for the pump chamber. There being no further comments or discussion, Laurel Almquist moved to approve the plan as variance for 256 Monomoscoy Road with the condition that a two-compartment tank be added that will meet the requirements for 100% capacity with 24-hours reserve for the pump chamber. Motion seconded by Mallory Langler. VOTE: Unanimous(3-0). 7:25—22 Bright Coves Way Mr. Harrington commented that the existing septic system at this address failed inspection. The proposed system is for four bedrooms, consisting of the existing 1500 gallon septic tank, and a proposed pump chamber to an off-center shaped 20'x 30'SAS, utilizing pressure distribution. The plan is before the board due to several variances, including a request to drop the proposed SAS one foot closer to groundwater than required. Raul Lizardi-Rivera stated that this is a system that was upgraded from a cesspool in the mid-1990's. It is a gravity system with leaching within 2' of existing groundwater. Based on the tie card for the existing system, it appeared to have been partially installed in the road layout. Requested variances are: 1) 1' variance from separation of pressure dose bed system to groundwater; 2) variance to foundation from 10'to 6'; 3)variance for cellar wall from 20' to 4';4)variance for pump station to foundation from 10'to 3'; and 5)variance to street sidelines from 10'to 2'. Mr. Rivera stated that the system is more than 140' 2
