Re: Subsurface Sewage Disposal System Plan for 29 Granville Lane(Map 106C,Lot 50)
Dear Mr. Cameron:
The proposed wastewater system design plan for the above site dated July 10, 2015 and received
on July 10, 2015 has been reviewed. Unfortunately, the plan cannot be approved until the
following items are corrected. The specific section in Title 5: 310 CMR 15.000, or North
Andover regulation that is not met by this design follows each item.
1. On sheet 1 of 2, the names of abutters from a recent tax map are not on the design plan
(NA 3.2).
2. On sheet 1 of 2, the percolation test log depicts the percolation test in the C1 horizon.
The percolation test was conducted in the Bw horizon. The field book notes from the
Board of Health representative are enclosed for reference.
3. It appears the leach field needs to be designed on a Class II soil (Bw horizon in TP 15-1)
instead of a Class I soil as depicted. There is a total of 47" of Cl and C2 soil in TP 15-1.
Although not a reason for disapproval, you may wish to consider the following:
4. Raising the bottom elevation of the impervious barrier since it is currently proposed at the
same elevation as the ESHWT.
5. To better assist the installer,please clearly indicate the proposed loading for the septic
tank(H-10 or H-20) and the materials for the frame and cover.
