Re: Subsurface Sewage Disposal System Plan for 463 Winter Street, Map 104A, Lot 69
Dear Mr. LeBlanc:
The proposed wastewater system design plan for the above site dated March 7, 2022 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. Provide names of all abutters (NA 3.2)
2. Identify the scale used for the plot plan(15.220)
3. Review proposed grading depicted at the northern end of the soil absorption system to
confirm if the 92.0 and 92.5 finished grades can be constructed as designed
4. Provide for test holes and percolation test identifying labels which can be seen
5. Indicate the current septic tank is to be abandoned in addition to the soil absorption
system which is noted (15.354 and NA 3.2)
6. Explain how the setback requirement for a soil absorption system to wetlands in North
Andover onsite wastewater regulations is being complied with or request relief(NA 3.9)
7. Depict the entire building sewer to be replaced if it is not currently PVC of schedule 40
rating
8. Indicate the building sewer is to have watertight joints, be laid on a firm and compact
base, in a straight line and on a continuous grade (15.222)
9. Depict the septic tank tees to extend 6" above the flow line (15.227)
10. Clarify which manholes are intended to be brought to final grade, which to within 6" of
final grade, and which to not have any riser(15.221 &228)
11. Indicate for the distribution box that all outlets are to be at the same elevation and that
they are to be laid level for the first 2' (15.232)

12. Provide for an inlet baffle or tee that extends at least 1"above the outlet invert of the
distribution box(15.232)
13. Indicate the distribution box is to be watertight(15.221)
14. Clarify if a riser will be needed to bring the distribution box to within 6"of final grade
(15.221 &232)
15. While identified in the calculations,the 2"force main pipe diameter should be labeled for
clarity during construction(15.254)
16. Indicate the alarm is to be on a separate circuit from the pump (15.231)
17. Provide for an effluent filter inside the septic tank, remove note indicating no effluent
filter is needed. Indicate brand and model of filter to be used(15.231)
18. Provide sand fill specifications to be provided by the installer, not a reference to Title 5
or another manual
19. Since the Enviro-Septic system proposed to be used is an alternative soil absorption
system the"Standard Conditions for Alternative Soil Absorption Systems with General
Use Certification and/or Approved for Remedial Use"will apply. Please provide the
following as required by the approval conditions
Section II(n:
The record drawings, approved by the LAA, must clearly indicate an area for the
best feasible replacement system that could be installed in the event that the
proposed Alternative Soil Absorption System fails or it is determined that it is not
capable ofproviding equivalent environmental protection
Section II(18):
certification by the Designer that the design conforms to the Approval, any
Company Design Guidance, and 310 CAM 15.000
Finally, while not a reason for disapproval please consider the following typographical errors
which could be adjusted:
A. Loading rate calculations refer to soil type"I I"when it is likely meant to state"II"
B. Throughout the plans reference"Title V"when it is likely meant to state"Title 5"
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
public health and the environment of North Andover.

Brian, Steve, Casey—
Not a bad design overall,just a number of items which are missing I think because these folks do not normally work in
North Andover.
Heads up that they are requesting a variance to the town regulations for reduced setback to a deck, and they also do not
meet the wetlands setback in the town's regulations either. We can deal with these when the revised plan comes in and
is likely ready for approval, but just wanted to call this out because we have not dealt with these items in quite some time.
