Ile: Subsurface Sewage Disposal System Plan for 1053 Salem Street,Map 104D, Lot 69
Dear Property Owner,
The previously approved revised wastewater system design plan for the above site, dated
December 16, 2013, has been voided due to a change in the flow to the system from the new
home. A revised plan was submitted on April 2, 2014 by Merrimack Engineering Services. This
plan has been reviewed and has been approved.
The revised design has been approved for use in the construction of a new onsite septic system,
designed for a 5-bedroom (maximum 11-room)home. This plan is good for 3-years from the
date of approval. During this time, a licensed septic system installer must obtain a permit and
complete this work, and a Certificate of Compliance be endorsed by the installer, designer and
the Town of North Andover or the plan approval will be voided.
As this septic system installation was in progress, when the increase of flow was identified, the
Disposal Works Permit (DWC)was voided due to change in the plans. A new DWC will be
issued to the installer and the installation can resume.
This approval is also subject to the following conditions:
1. Must comply with the "Standard Conditions for Alternative Soil Absorption Systems with
General Use Certification and/or Approved for Remedial Use"
System owner acknowledgement letter is to be submitted before COC

1053 Salem Street April 3, 2014
Since the Infiltrator Chamber system is proposed as 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(18):
- a certification, signed by the Owner of record for the property to be served by the Technology,
stating that the property Owner:
1. has been provided a copy of the Title 5 I/A technology Approval,the Owner's
Manual, and the Operation and Maintenance Manual, and the Owner agrees to comply
with all terms and conditions;
2. for Systems installed under a Remedial Use Approval, the owner agrees to fulfill
his responsibilities to provide a Deed Notice as required by 310 CMR 15.287(10) and the
Approval;
3. for Systems installed under a Remedial Use Approval, the owner agrees to fulfill
his responsibilities to provide written notification of the Approval to any new Owner, as
required by 310 CMR 15.287(5);
4. if the design does not provide for the use of garbage grinders,the restriction is
understood and accepted; and
5. whether or not covered by a warranty,the System Owner understands the
requirement to repair, replace, modify or take any other action as required by the
Department or the LAA, if the Department or the LAA determines the System to be
failing to protect public health and safety and the environment, as defined in 310 CMR
15.303.
2. If site conditions are found in the field to be different from those indicated on the design
plan and/or soil evaluation,the originally issued Disposal System Construction
Permit is void, installation shall stop, and the applicant shall reapply for a new Disposal Systems
Construction Permit(3 10 CMR 15.020(1)).
Please feel free to contact the office with any questions you may have. We look forward to
working with you to install 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.
