Dear Mr. Osgood:
The proposed wastewater system design plan for the above site dated May 3, 2007 and received
on October 16, 2008 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. Please state the local variance request on the design plan((3 10 CMR 15.220(4)).
2. The cover letter is requesting a Local Upgrade Approval and does not specify the section
of the regulation. However, a variance from North Andover Regulations section 7.05
must be requested not a Local Upgrade Approval from Title 5, 310 CMR 15.000.
3. Please show all the legal boundaries of the property (3 10 CMR 15.220(4)(a)),
4. Please provide a north arrow(3 10 CMR 15.224(4)(8)).
5. The bottom of the Infiltrator Chambers are shown as 96.25' and the detail shows the
chambers to be 12" in height. Please explain how the breakout elevation was calculated
to be 97.48' instead of 97.25' (top of chambers).
6. Please clearly show the breakout elevation is met with an existing spot grade or proposed
finish grade (3 10 CMR 15.255(2)).
7. Please indicate that the finish grade over the leaching facility shall a minimum slope of
0.02 feet per foot. (3 10 CMR 15.240(10)).

the site plan. Construction Note#15 describes the specifications of an impervious barrier
to be used but it is not shown on the site plan.

20' width and the cross section states a 19.5' width.
