Dear Mr. Lagrasse:
Please see your comments below with notes regarding revisions to the proposed septic design plan.
1. Please indicate the size and material of the access covers proposed above the septic tank.
A note has been added to Sheet R-2 in the system profile next to the septic tank noting the requirement
for three 20"diameter cast iron or polyethylene covers in accordance with 15.228(2).
2. The DEP approved brand and model of the effluent filter should be indicated on the design
plan. in addition, please indicate the required annual maintenance for the effluent filter on
the design plan (310 CMR 15.227)(7)).
Please see note 28 on Sheet S-2 and note within septic tank profile on sheet S-1.
3. On sheet 1 of 2,it appears the 16"tree adjacent to the D-Box will need to be removed. If so,
please indicate this on the design plan to ensure the installer is aware of this installation
requirement.
A note has been added to Sheet S-1 indicating that the 16"tree near the D-Box is to be removed.
If you have any other questions or concerns please let us know.
