RE: Subsurface Sewage Disposal System Plan 29 Granville Lane (Map 1060, Lot 50)
Response to Comments
Dear Ms. Grant:
We are in receipt of your review letter dated July 27, 2015. 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

We trust that these responses satisfy your questions/concerns outlined in your review letter.
As you may recall, in our original application submitted to your office on ]uk/ IO, 2015, we
included Form 9A-App[icetioD for Local Upgrade Approval (a copy Of the application is
attached). We are requesting a one foot reduction in the setback from the bottom of the [each �
bed to the estimated seasonal high water table. Please schedule us to appear before the Board �
th
of Health at their next regularly scheduled meeting on Thursday, August 27 .
