Re: Subsurface Sewage Disposal System Plan for 285 Rea Street, Map 38, Lot 118
Dear Homeowners:
The proposed wastewater system design plan, for the above site, dated September 23, 2013 with
a final revision dated October 15, 2013, received on October 17, 2013 has been approved.
The design has been approved for use in the construction of a fully compliant upgraded onsite
septic system, designed for a 5-bedroom (maximum 11-room) home. This plan is good for 2-
years from the date of the failed Title V Inspection, conducted by a licensed state inspector on
July 26, 2013,however in this case the owner has agreed to have this system installed as soon as
possible.
During this time, a licensed septic system installer must obtain a permit and complete this work;
all paperwork including the "Deed Notice" etc. must be submitted; and a Certificate of
Compliance be endorsed by the installer, designer and the Town of North Andover or the plan
approval will be voided.
This approval is also subject to the following conditions:
1. 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)).
2. 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 net. 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.
3. Prior to a Certificate of Compliance is issued,proof of the following shall be
submitted to the Health Office.
a. "Deed Notice". As a reminder, 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):
- certification by the Designer that the design conforms to the Approval, any Company
Design Guidance, and 310 CMR 15.000; and
- 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.
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.

North Andover, MA
We would like to be included on the meeting agenda of the Board of Health scheduled for 9/26/13, to
discuss the progress and intent of the Septic Design being done for 285 Rea St. We would also like to
discuss the feasibility of getting BOH approval for a building permit contingent on installing the approved
system, prior to the system actually being installed.
We are currently in the middle of one portion of the work at 285 Rea St., with a second large portion of
the work needing a permit to continue. The new septic system is being sized to accommodate the new
work and room count.
Thank you for your consideration.

Dear Board of Health,
As you aware, we have submitted the septic system upgrade plans for 285 Rea
Street, designed by John Sullivan, the for approval by the Town of North Andover
Health Department. We kindly request that the Health Department accept this
letter of agreement in regards to the septic system repair at 285 Rea Street.
The following are the reasons for our request;
0 We are committed to completing the septic system upgrade as soon as it
is approved. We are a family of five and it is of the utmost importance to have a
fully functioning septic system as soon as possible. We are of the understanding
that septic installations cannot occur between Nov. 30 the March 1st of each
year. Thus, we are hopeful to have it installed by the November deadline &this
is our goal. We are 1009 ready to move forward once approved.
We are planning on receiving bids on the septic system upgrade and will
be securing a contractor soon. if weather permits, we would install the system
before winter and heavy snow coverage. If not, at worst case we will complete
the installation of the septic system no later than March-April 2014.
Thank you,

Ms. Sawyer;
Enclosed are three (3) sets of the revised Septic Plans for the above referenced property.
The following changes/revisions were made based on the review letter;
1) Abutter names have been added to the plan
2) The existing leaching pits have been added to the plan and a note that they shall be abandoned in-
place.
3) Note on excavation of C-layer extending 6"into native material has been removed.
4) Cross Section of Infiltrator field has been revised accordingly.
5) Design analysis properly identifies system as "infiltrator"now.
6) Wetland delineator and date of delineation has been added to the plan.
If you should have any questions or comments please feel free to contact me.

Re: Subsurface Sewage Disposal System Plan for 285 Ilea Street,Map 38 lot 118
Dear Mr. Sullivan,
The proposed wastewater system design plan for the above site dated September 23, 2013 and
received on September 24, 2013 has been reviewed. Unfortunately,the plan cannot be approved
until the following minor 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. Did not locate abutters' names. Please provide the names of abutters from recent tax map
(NA 8.020)).
2. Existing system is not located on the plan view on page 1 and note for abandonment may
need to include notes for the leaching area if needed. .354 &NA 3.2
3. Clarification of note regarding excavation into the "C"layer on page 1. This was a
previous NA requirement.Not sure if the engineer is proposing this for local or state
requirements. Unless a state requirement this is not needed
4. Field Cross Section notes appear to be from another plan it notes; "Cultec units" and data.
Filter fabricmirafi enclosure; 5 foot separations etc. Please review and change to reflect
this design. Please correct.
5. Design Analysis notes Cultec units on last line. Please correct to "infiltrator"
6. Please note wetland delineator.
Plan notes "Deed Notice". As a reminder, 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
