RE: Subsurface Sewage Disposal System Plan 29 Granville Lane (Map 106C, 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 (LIAR) 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

water table at the front of the system and a 1.8' separation between the bottom of the
barrier and the estimated seasonal high water table at the rear of the system.
5. The proposed loading for the septic tank has been labeled as "H-10" on the septic tank
detail on Sheet 2 of 2 on the design plan. The materials to be used for the frames and
covers have not been specified. This allows the installers to choose their preferred
choice/material of the frames and covers to be used.
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 July 10, 2015, we
included Form 9A-Application 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 leach
bed to the estimated seasonal high water table. Please schedule us to appear before the Board
of Health at their next regularly scheduled meeting on Thursday, August 27tH
If you should have any questions please do not hesitate to contact me.

I do not believe we have received a revised plan for 700 Middleton Street.That should be submitted ASAP so we have
time to review prior to the meeting. Unfortunately I will only have a limited amount of time on Tuesday to review a
revised plan (if submitted). My schedule is already booked with soil testing and other project deadlines and Dan is on
vacation until Wednesday.
| vvVu|d recommend Dan and the 8OH chair discuss this idea of"walk ons" in more detail soon because it appears to add
unnecessary time pressure to all parties involved inoproject. The 8C}H meeting schedule seems very clear about
agenda items being requested in writing 10 days prior to the 0OH meeting.
| will review 1Q6 Ingalls street either today orTuesday.
