Re: 514 Winter Street
Dear Ms. Sawyer:
We are in receipt of your review letter dated 4-17-06 regarding the above referenced
project.
The plans have been revised to address your comments. Also submitted is an attachment
addressing pump curves and buoyancy calculations as insufficient space exists on the
plan. Also enclosed is a revised copy of the L.U.A. Form.
With regard to the wetland issue, Epsilon Associates, Inc. performed the delineation and
involved the conservation agent so as to have agreement on the delineation.
Requiring a conservation filing for the sole purpose of the delineation would be an
unreasonable requirement of the homeowner in a process which is already financially
overwhelming, especially when a subsequent filing with the Conservation Commission is
necessary.
We hope we have adequately addressed your comments and respectfully request the plan
be approved as re-submitted.
Very truly yours,
MERRIMACK ENGINEERING SERVICES
William Dufresne

Form 9A - Application for Local Upgrade Approval
DEP has provided this form for use by local Boards of Health. Other forms may be used, but the
information must be substantially the same as that provided here. Before using this form, check with your
local Board of Health to determine the form they use.
Form 9A is to be submitted to the Local Board of Health for the upgrade of a failed or nonconforming
septic system with a design flow of less than 10,000 gpd, where full compliance, as defined in 310 CMR
5.404(1), is not feasible.
310 CMR 15.403(4) requires the system owner to provide a copy of the local upgrade approval to the
appropriate Regional Office of the Department of Environmental Protection, Bureau of Resource
Protection, Title 5 Permitting Program, upon issuance by the local approving authority and before
commencement of construction.
System upgrades that cannot be performed in accordance with 310 CMR 15.404 and 15.405, or in full
compliance with the requirements of 310 CMR 15.000, require a variance pursuant to 310 CMR 15.410
through 15.417.
NOTE: Local upgrade approval shall not be granted for an upgrade proposal that includes the addition of
a new design flow to a cesspool or privy, or the addition of a new design flow above the existing approved
capacity of an on-site system constructed in accordance with either the 1978 Code or 310 CMR 15.000.

Re: Subsurface Sewage Disposal Plan for 514 Winter Street,Map 104A,Lot 79
Dear Mr. Donato:
The proposed wastewater system design plan for the above site dated March 10,2006 and received on March 20,
2006 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. The septic tank and pump chambers are both in the groundwater. Please provide buoyancy calculations for
each tank.
2. Volume calculations including flow back were not included in the calculations. Please note that the Health
Department requests that this be done on all systems. As this run would be a negligible result it is not
requested for this site,however in an effort of consistency please include flow back in all calculations.
3. Please provide pump performance curves in order to verify the calculated flow against the head.
4. It is noted that the North Andover Conservation Commission has not approved the wetland boundary depicted
on the plan as the Commission has not reviewed this plan to date. If this wetland line is changed by the
Commission a plan must be submitted to this office with the changes. In addition, it would be best to submit
verification of the wetland line prior to the Board of Health meeting so that the members may be sure they are
voting on an accurate variance.
5. Please clarify or correct the Application for Local Upgrade Approval which was submitted. Part B of the
Application requests information about relocating a water supply well and you provided information in this
section,though the design plan does not indicate a water supply well is present for this dwelling. It is assumed
that there is no on site water well and this request should be under"other"as it relates to a town water supply,
on the line below,rather than well.
Additionally,you might wish to consider the following in your revised plan:
• Using an effluent filter in the primary(septic)tank
• Adding a note to the Notes section regarding the required relocation of the waterline
Please submit the written request to be on the next available Board of Health meeting agenda for the purpose of the
variances found listed on the plan. The May meeting will be held on May 25,2006.
Please feel free to contact the office 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.
Sincerely,;
i
Susan Y. Sawyer,REHS/RS
