Dear Mr, Christiansen,
The proposed wastewater system design plan for the above site dated October 20, 2017 and
received on November 3, 2017 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 where applicable.
1. Abutters from the most recent tax map were not depicted on the design plan (NA 3.2).
2. A variance request is required to propose a building sewer line less than 50' to a private
well (NA 3.2).
3. The variance request for the reduced setback from the leaching area to the wetland
resource area should indicate the distance from the reserve area (51') as well as the
primary area(55').
4. Please be prepared to explain the need for the variance(s) request to the Board of Health
at a public meeting, specifically as it relates to NA section 8.1.
5. On sheet 1 of 2,the existing contour lines were not labeled.
6. Proper abandonment of the existing septic system should be noted on the design plan
(3 10 CMR 15.354&NA 3.2).
7. On sheet 1 of 2, General note 48 is incorrect.
8. On sheet 1 of 2, the foundation drain location is not indicated and the elevation is not
shown on the design plan (NA 3.2).
9. The inspection port location was not shown on the design plan(31.0 CMR 15.240(13)).

10. The breakout elevation for the leach area is not depicted on the design plan,
11. On sheet I of 2, the ]each trench detail does not depict double washed stone (3 10 CMR
15.247).
12. The distribution box is required to be H-20 loading (NA 3.2).
13. Based on the soil testing results, it appears the bottom of septic tank and pump chamber
will be below the ESHWT. Therefore, buoyancy calculations are required(3 10 CMR
15.221(8)).
14. Oil sheet 2 of 2,the number of dosing cycles were not depicted (3 10 CMR 15.220(4)(r)).
15. On sheet 2 of 2, it appears the drain back volume for the 2" force main of 1.6 gallons is
incorrect. Approximately 3.4 gallons appears to be the correct drain back volume.
16. On sheet 2 of 2, In the pump chamber detail please indicate the distances between the
pump floats in inches to better assist the installer during construction.
17. Please indicate the ESHWT in the location of the septic tank and pump chamber in order
to confirm the inlets and outlets are above the ESHWT (3 10 CMR 15.227(5)).
18, An effluent filter is required before or inside the pump chamber(310 CMR 15.23:1(10)).
19. On sheet I of 2, a swale is required for proposed finish grading within 5' of the property
line (310 CMR 15.255(2)).
Please feel free to contact the office or Mill River Consulting at 978-282-0014 with any
questions you may have. We look forward to working with you to obtain a wastewater treatment
and dispersal system which will be in compliance with all regulations and assure protection of
