Re: Subsurface Sewage Disposal System Plan for 326 Forest St.Man 106A lot 13
Dear Mr. Biondi:
The proposed wastewater system design plan for the above site dated June 25, 2014 with a final
revision date July 28, 2014 and received on July 30, 2014 has been approved.
The design has been approved for use in the construction of a replacement onsite septic system
for a 4-bedroom (max 9-room)home. This plan is generally good for 3-years from the date of
approval however, as this is for a repair system, this is reduced to 2- years.
The plan received the following local upgrade approval.
1) Use of only one deep hole as opposed to the two required
2) The use of a reduction of the distance from the SAS to the foundation from 20 to 15 feet.
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. 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 also subject to the following conditions:
1. Please keep the attached DEP Form 9b for your records (attached)
2. This system utilizes an infiltrator system and the owner has certified the
understanding of this system, as found in the document submitted (see attached)
3. 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)).
4. It is the responsibility of the applicant and/or the applicant's septic system designer,
septic system installer or other representative to ensure that all other state and
municipal requirements are met. These may include review by the Conservation
Commission, Zoning Board, Planning Board, Building Inspector, Plumbing Inspector
and/or Electrical Inspector. The issuance of a Disposal System Construction Permit
shall not construe and/or imply compliance with any of the aforementioned
requirements.
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,
Susan Y. Sawyer, REHS/RS

7. When the System is used with a secondary treatment unit approved in accordance
with 310 CMR 15.284 or 15.288, additional reductions in soil absorption system
may be allowed. In these situations the reduction in the SAS cannot exceed the
maximum allowed under the secondary treatment units approval. In no instance
shall the reduction in the soil absorption system area required in 310 CMR 15.242
exceed the maximum reduction allowed for alternative systems approved in
accordance with 310 CMR 15.284.
II. Special Conditions
1. The System is an approved Alternative Chamber for use as an Alternative Soil
Absorption System. In addition to the Special Conditions contained in this
Approval, the System shall comply with the "Standard Conditions for Alternative
SAS moth General Use Certification and/or Approved for Remedial Use" (the
'Standard Conditions'), except where stated otherwise in these Special
Conditions.
2. New Construction This Certification is for the installation of a System to serve
new construction or an existing facility with a proposed increase in flow, for
Infiltrator Chamber,Infiltrator Inc. Page 5 of 6
Approval for General Use—May 22,2014
which a site evaluation in compliance with 31 0 CMR 15.000 has been approved
by the Approving Authority and the site meets the siting requirements for new
construction, as provided in Paragraph 6 in section II Design and Installation
Requirements of the Standard Conditions.
3. Remedial Site This General Use Certification also applies to the installation of a
System for the upgrade or replacement of an existing failed or nonconforming

provided in Paragraph 7 in section lI Design and Installation Requirements of the
Standard Conditions
4. The System shall be exempt from the minimum inlet spacing requirements of 310
CMR15.253.
5. The System shall have a minimum of one inspection port through the top of one

approved, are subject to other Special Conditions and limitations;
c) The minimum separation distance between any two trenches shall be two
times the effective width or depth of each trench, whichever is greater, or
where the area between trenches is designated as reserve area,three times the
effective width or depth of each trench, whichever is greater(3 10 CMR
