for the record. His question was whether the finished grade of the.driveway would be the same as the <br /> existing grade,once the new system is installed,and Mr. lamele answered that it would be. Mr. Neild had <br /> no further questions. <br /> There being no further comments or discussion, Mallory Langler moved to approve the septic plan as <br /> designed for 30 Wilsons Grove, provided that a soil evaluation is performed by a Health Agent at the time <br /> of installation, and an engineered as-built is provided. Motion seconded by Veronica Warden. VOTE: <br /> Unanimous(3-0). <br /> 7:20—438 Quinaquisset Avenue <br /> Mr. Harrington commented that a request has been made by the owner of 438 Quinaquisset Avenue to <br /> install the Title V system that was designed by Down Cape Engineering in 2018, which consisted of a <br /> MicroFAST 0.5 denitrification tank, a UV disinfection unit, and a 20' x 25' pressure distribution le9ching <br /> field. The request was made to connect to the Willowbend sewer collection system but the DEP issued a <br /> decision that the owner must modify the existing Groundwater Discharge Permit (GWDP)for Cotuit Bay <br /> Condominiums and Southworth Willowbend to allow a non-condominium property to connect to that <br /> WWTP. Both Cotuit Bay and Southworth Willowbend were still allowing the owner to tie into the WWTP <br /> collection system;however,the owner chose not to go forward with the sewer tie-in. The owner reported <br /> that the cost to modify the GWDP would far exceed the cost for the Title V system. <br /> Dan Ojala,of Down Cape Engineering, introduced himself for the record,_and remarked that this property <br /> has sat vacant for some time. Mr.Ojala stated that Cotuit Bay and Willowbend were amenable to allowing <br /> the tie-in but,in speaking to DEP,the process became more complex from a legal perspective. Therefore, <br /> the owner asked Down Cape to present the original Title V design from 2018 to the Board,to avoid a very <br /> onerous and time-consuming process. Mr.Ojala explained that,while not as good as sewer,the proposed <br /> Title V system does provide a tremendous improvement over existing conditions. He further explained <br /> that vertical separation between the groundwater and the bottom of the system is critical for the removal <br /> of pathogens and virus. He briefly discussed the benefits of pressure-dosing. <br /> Ms. Langler asked if the plan had been before the Conservation Commission, and Mr. Harrington <br /> answered that it had, but he did not know the particulars of the approval. Chair Baumgaertel asked if this <br /> would be a general approval for nitrogen reduction or standard secondary treatment,and Mr.Harrington <br /> answered that this is not in a Zone II,so it would be a remedial approval. <br /> There being no further comments or discussion, Mallory Langler moved to approve the septic plan as <br /> designed for 438 Quinaquisset Avenue, with the condition that all DEP remedial approval and Board of <br /> Health regulations are met by the owner and operator of the UV and denitrification system. Motion <br /> seconded by Veronica Warden. VOTE: Unanimous (3-0). <br /> 7:25—24 Porthole Drive <br /> Mr. Harrington commented that the owner of this property is proposing a full foundation addition to his <br /> dwelling that requires a variance to the existing SAS. A variance of 13' is requested to allow 7' between <br /> the cellar wall and the SAS. In 2007,an emergency upgrade was performed to replace the failed leach pit. <br /> The existing SAS is approximately 17 feet from the existing cellar wall.The effluent only extends 5'laterally <br /> from the SAS,and the cellar wall is proposed With a 40 ml vinyl barrier. Title V requires 20'to a cellar wall <br /> and the owner is creating his/her own hardship;therefore,the Board does not have to grant this variance. <br /> An addition can be placed on Sono tubes where no variance would be required. The property is not in <br /> 2 <br />
