Re: Subsurface Sewa ge Disposal System Plan for 191 Granville Lane (Mal) 106C Lot 62
Dear Mr. Lynch:
The proposed onsite wastewater system design plan for the above site dated 4/4/25 with a final
revision date of 5/2/25 has been approved for issuance of a Disposal System Construction Permit
(DSCP). Once issued, a DSCP will authorize the construction of the onsite wastewater system
per the plan referenced above and as allowed under'Title 5 of the Massachusetts Environmental
Code (310 CMR 15.000). You will need involvement from the designer of the onsite wastewater
system throughout the installation process so you should be sure to coordinate with them.
The design has been approved for use in the construction of an upgrade on-site wastewater
system for a 4-bedroom (maximum 9-room) home utilizing the existing septic tank and pump
chamber with pump and a standard stone-and-pipe soil absorption system as indicated on the
design plan.
The goal for system upgrades is to achieve full compliance with state and local onsite wastewater
regulations. In this instance full compliance was not achieved because the design includes a
request for a Local Upgrade Approval and a variance seeking to vary from the standards of full
compliance. This letter serves to document the endorsement of the Local Upgrade Approval and
variance by the North Andover health Department.
This design plan approval is valid for 2 years from the above date. During this time, a licensed
septic system installer should obtain a permit and complete this work, and a Certificate of

Compliance be endorsed by the installer, designer, and the"Town of'North.Andover. If these
activities are not completed within this time period, then it ispossible a new design plan will
need to be completed and submitted for review. In the event an imminent health problem such as
sewage backup into the dwelling is occurring the North Andover Board of Health may reduce the
time period for which this plan is valid.
This approval is subject to the following conditions. Please be sure to review these with the
designer and installer.
Prior to the issuance of a Disposal System Construction Permit:
a. Three additional paper copies of the design plan are to be provided to the office
Throughout the project:
a. If site conditions are found in the field to be different from those indicated on the
design plan, installation of the onsite wastewater system shall stop and the
designer and this office notified within 24 hours
b. If groundwater is present at the bottom portion of the excavation for the soil
absorption system (SAS) the excavation is to be dewatered prior to the placement
of any fill. No fill is to be placed for the SAS during rain or snow storms. Prior to
placement:of any needed fill in the SAS, the bottom is to be scarified and
relatively dry and the fill material is to be stockpiled at the edge of the excavation
and filled in gradually
c. Inspections are to be performed by the designer of the onsite wastewater system
as needed to properly oversee and document construction. At a minimum these
are the initial excavation, prior to baekfidling, and during backfilling as well as
any other component of the construction which the designer wishes to examine
d. Inspections are to be completed by the Town ofNorth Andover at a minimurra as
follows:
i. Bed bottom
ii. Tank bottom
iii. Final installation of components, confirmation of proper component
selection, examination of construction methodology, and system operation
iv. Final grade
v. Sand fill will be collected frorn at least one location and analyzed for
compliance with specifications in Title S
e. No components are to be covered until a final component inspection has been
completed
f. No excavation for or work associated with construction of the soil absorption
system is to occur from November 30 to April 1
After construction:

h. If changes have been made to the approved plans, then preparation of an as-built
plan is required to be completed by the designer. If no changes have been made
to the approved plans, then the approved plan shall be modified by the designer to
show the distances from a Known Structure to the system components.
i. No sewage shall be discharged to the onsite wastewater system until a Certificate
of Compliance has been issued by this office
In addition, you should be aware of the long-term operation guidelines of an onsite wastewater
system (these are not part of the DSCP but are mentioned below as information for the property
owner):
1. An onsite wastewater system can function as an integral part of the infrastructure of
the property if it is properly operated and maintained. This is the responsibility of the
owner of the property and is generally not specified by regulation. You are
encouraged to contact a wastewater system pumper/service provider to partner with
you to implement steps needed to assure thelongevity of the onsite wastewater
system being installed at this location.
2. The onsite wastewater system specifies the use of an effluent filter inside the tank.
This component is required to be examined at least annually and cleaned as needed
The issuance of a DSCP does not construe and/or imply compliance with any permits, approvals
or licenses which might be needed from other agencies such as the Conservation Commission,
Zoning Board, planning Board, Building Inspector, Plumbing Inspector and/or Electrical
Inspector.
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
