Please find enclosed two (2) copies of the design plan that have been revised to address your comments listed below. The following numbered responses correlate with your numbered comments from your review letter: 1. The names of direct abutters have been added to Sheet 1 of 2 on the design plan. 2. The percolation test log has been revised to depict the correct location in the Bw horizon (at a depth of 35") on Sheet 1 of 2 of the design plan. 3. The design plan, calculations, soil absorption system and details (Sheet 1 and Sheet 2) have been modified to correlate with a Class II soil long term acceptance rate (LTAR) of 0.60 gpd/sq.ft.. This change slightly increased the size of the soil absorption system, caused some minor changes to grading, extended the retaining wall and shifted the septic tank and distribution box northerly by approximately 2'. The details and system profile have been updated to reflect these changes. Although there is only a total of 47" in the C1 and C2 horizons, the test hole did not hit refusal (i.e. (edge). This can be seen in the test hole notes provided by the Board of Health representative where 107+ is noted in the Test Pit 15-1 notes. However, since the percolation test was conducted in the Bw soil horizon, this soil horizon is eligible to count towards the 4' of pervious material required. Therefore, Test Pit 15-1 has 6.1' of naturally occurring pervious material and Test Pit 15-2 has 5.8' of naturally occurring pervious material, which are both greater than the required 4'. 4. The bottom of the impervious barrier has been raised to an elevation of 97.2', creating a separation of 1' between the bottom of the barrier and the estimated seasonal high CIVIL ENGINEERS o LAND SURVEYORS e ENVIRONMENTAL CONSULTANTS a LAND USE PLANNERS 447 Boston Street(U.S. (route 1) Topsfield, MA 01983 978.887.8586 F-AX 978.887.3480 Providing Professional Services Since 1978 www.morincameron.com | Ms. Michele Grant August 6, 201 J water table at the front of the 3VSt8nn and o 1.8' separation between the bottom of the barrier and the estimated seasonal high wmtmrtabieattherearmfthosystenn. 5.
