Re: Septic System Design Plan for 259 Granville Lane-Map 106A,Lot 152,Subdivision Lot 22A
Dear Mr.Dufresne:
The proposed wastewater system design plan for the above site dated February 27,2008 and received in our office
on March 24,2008 and 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(NA)regulation that has not met by
this design follows each item for your convenience.
1. Please provide a benchmark within 50-75 feet of the system(220(4)(q))
2. Please adjust the design to provide for the minimum slope required for the building sewer(222(6))
Please provide volume calculations which include the flow back volume for the pump chamber(231(2))
4. Please provide a pump performance curve(220(4)(x))
5. Please provide the correct number of deep observation holes in the disposal area or request a Local Upgrade
Approval(102(2))
6. Please use leach trenches or provide an explanation as to why trenches were not used(240(6))
7. Please specify the final grade over the leach field to be a minimum of 0.02ft/ft(240(10)).
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.
Sincerehy,

RE: 259 Granville Lane I'OWN -;

Dear Ms. Sawyer,
We are in receipt of your review letter dated 4-10-08 for the above referenced project.
Item#1 refers to a benchmark which is clearly shown on the plan as the top of foundation
and is within 50 -75 ft. of the system components. We are unclear as to the reviewers
comment.
Item#2 refers to the minimum slope of the building sewer which is shown on the plan
and does meet the minimum requirement and we are again confused as to the reviewers
comment.
Item#3 has been addressed and added to the plan.
Item#4 has been addressed. See copy of pump performance curve submitted herewith.
Item# 5 refers to the number of deep holes. Site conditions were such that holes were
dug where possible. The location of the existing leach field precluded us from digging 2
holes which fall within the proposed s.a.s. Both holes represent consistent soil conditions
and water tables and it is reasonable to assume that conditions are consistent within the
area of the proposed system. It is unfortunate to require a Local Upgrade for this site
when all the design requirements are met. Issuance of the L.U.A. is solely for number of
test holes which could ultimately restrict the firture use of the property however a
completed L.U.A Application is submitted herewith. Perhaps a deep hole could be
performed at time of excavation inspection so as to eliminate the need for a L.U.A.
Item#6 refers to the use of trenches and as we have argued in the past, construction of
trenches in this situation is less feasible as a field. Trenches would require a greater area
and associated cost and would be constructed in fill and not function as the code
intended.
Lastly, item#7 refers to the final grade over the system. The typical end section specifies
the grading requirements and the plan view shows the existing/proposed contours which
also represent the grading requirements. Both comply with Title 5 and we are again
confused as to the reviewers' comment.
We have enclosed 3 copies of the revised plan and respectfully request that the design be
approved as re-submitted.
We appreciate your prompt attention to this matter.
Very truly yours,

Re: 259 Granville Lane, map 106A Lot 152, North Andover, Subsurface Disposal System
Installation
Dear Homeowner,
The North Andover Board of Health has completed review of the onsite wastewater
treatment and dispersal system design plans for the above referenced property submitted on your
behalf by Merrimack Engineering Services dated April 24, 2008 and received by this office on
April 22, 2008. The design has been approved for use in the construction of a replacement onsite
wastewater system for a 4-bedroom(maximum 9-room horse)
This plan is valid for two years from the date of a septic system inspection that did not
meet the acceptable criteria in the state regulations, January 9, 2008. 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(BOH) may reduce the time period for which this plan is valid.
This plan includes an approval of a local upgrade approval (LUA) for the variance to 310
CMR 15 102(2), requiring a minimum of two deep hole tests within the primary leaching area.
With this LUA, the Health Department accepts that the soil characteristics are likely consistent
within the system area even though it does not meet the minimum requirements set by Title V.
No additional action is needed on this issue.
Please also note upon second review that the initial reviewer was found mistaken on
observations listed on the disapproval letter and noted as#1, #2 and#7. Please disregard these
items. Item#6 was addressed in the response letter for reasons given, which if listed on the plan
would not have been challenged. The document submitted for#4 will be attached to the plan to
provide information to the installer.
This approval is subject to the following conditions:
1. The building sewer invert shall be checked prior to construction and the engineer shall be
consulted if any adjustments are needed to the placement of the tank elevations.
2. Keep the attached Form 9b for your records
1600 Osgood Street,North Andover,Massachusetts 01845
Phone 978.688.9540 Fax 978.688.8476 Web www.towoofnorthandover.com
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(l)),
4. It is the responsibility of the applicant and/or the applicant's designer, 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.
Your effort to provide a properly functioning onsite wastewater treatment and dispersal system
for your property is greatly appreciated. The Health Department may be reached at 978-688-
9540 with any questions you might have.
