Re: Subsurface Sewage Disposal System Plan for 1049 Salem Street (Map 104D,Lot 70)
Dear Mr.Nemchenok:
The proposed wastewater system design plan for the above site dated. October 21, 2013 and
received on October 31, 2013 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 regulation that is not met by this design follows each item.
1. A Local Upgrade Approval for being less than 20' from the soil absorption system to the
cellar wall must be requested. Please revise the Form 9A and note the Local Upgrade
Approval request on the design plan(3 10 CMR 15.405(1)(k)).
2. A riser to within 6 inches of finish grade is required above the distribution box if greater
than 9 inches below grade. Magnetic tape cannot be used as an alternative to providing a
riser. Please modify the note in the "Graphic Scale" on sheet 2.
3. On sheet 1 of 2, the existing system(s) are not depicted on the site plan. Please show the
existing system(s) (NA 3.2).
4. Please indicate the required maintenance for the proposed effluent filter(3 10 CMR
15.227(7)).
5. The soil and percolation test results are required to be submitted on current DEP forms 11
and 12 (NA 3.2).
6. On sheet 1 of 2, it does not appear that the breakout elevation is met on the northern and
western sides of the leach field. Please demonstrate the breakout elevation will be met
with proposed spot elevations (3 10 CMR 15.255(2)).
7. The breakout elevation on the high end of the leach field (152.90) is not depicted on the
design plan. This elevation should be used as the breakout elevation on the high end of
the leach field.

8. The limit of soil removal beneath the leach field is not indicated on the design plan. This
should be shown or depicted in order for the installer to be aware of what layers of soil
need to be removed prior to the installation of sand fill.
Although not reasons for disapproval you may wish to consider the following:
- Moving the proposed driveway beyond the 5' sand overdig.
- Considering the close proximity of the driveway proposing boulders or other means along
the edge of the leach field area will help to prevent vehicular traffic on the leach field.
Please feel free to contact the office with any questions you may have. We loop 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.

RE: 1049 Salem Street(Map 104D,Lot 70)
Dear Susan,
We are in receipt of your review letter dated November 13,2013 for the above referencedn`r✓�`" z
site.
With regard to item#1,the soil absorption system setback to the foundation is not lv, �1`
applicable,because the elevation of the cellar floor is above the breakout elevation of the
s.a.s., the setback to a slab applies not the setback to a foundation. The setback from the
soil absorption system to a slab is 10' and has been met. of .
��V \
� `
(� With regard to item#3,we have no knowledge nor are there records of the existing V
systems.Notes 12 & 13 specify what action is to be taken relative to the existing systems.
With regard to item#5,DEP form 11 is lengthy, time consuming to prepare,and requires ��
0� research from many other sites relative to geology,water resources and other criteria
which play no role in the septic system design process, as such, shorter forms have been
developed and accepted by DEP and local Boards of Health and are commonly used. The
4- form submitted with our plan has been accepted in NA in the past and meets the
requirements of Title 5, 15.103(1). We have had this discussion in the past,is it no longer
iV acceptable in North Andover?
With regard to item#6 ,the design does meet high and low breakout elevations 15
=' C feet from the system and the 152 contour demonstrates this,however we did add
proposed spot elevations to the plan to further demonstrate this.
With regard to item#8, adequate information exists on the plan which indicates what soil
is to be removed beneath and within 5 feet of the system. The 5 foot around area is
shown,the elevation of soil removal is indicated at the test pits,and note 4 specifies the
material removal requirements. Additionally both the designer and the Town perform an
excavation inspection to assure proper soil removal beneath the system, and lastly,
anyone who possesses an installers license has demonstrated their knowledge of this and
many other requirements of Title 5,

If the reviewer is suggesting we graphically show the vertical limit of removal on the
profile, as designers we are unable to determine the precise limit of removal as the only
information we have to determine that depth is the test pits,the test pits are only
reflective of the soil at the location of the test pit. Showing a vertical limit on the plan
which represents the vertical limit of soil removal throughout the entire area of the soil
absorption system would bind the contractor to the limit shown on plan rather than actual n
field conditions. The plan as submitted has been accepted by NA in the past and no issues ."A
have arisen that suggest the contractor cannot clearly identify the limit of soil removal, as
such,we feel the plan is satisfactory and adequate inspections exist to assure the soil
removal requirement is met. o J
With regard to items#2,the plan has been revised accordingly.
Submitted herewith are 3 copies of the revised plan,we feel your concerns have been
adequately addressed and respectfully request that the plan be approved as re-submitted.
You uly,
William Dufresne

Re: Subsurface Sewage Disposal System Plan for 1049 Salem Street, Map 104D,Lot 70
Dear Property Owner,
The proposed wastewater system design plan for the above site dated October 21, 2013 with a
final revision dated December 16, 2013, received on December 17, 2013 has been approved as
submitted by Merrimack Engineering Services.
The design has been approved for use in the construction of a new upgraded onsite septic system,
designed for a 4-bedroom (maximum 9- 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.
At a regularly scheduled meeting of the Board of Health,this plan received the following
approvals by the members.
1. Local upgrade - Setback from S.A.S. to garage slab from 10' to 5'
2. Local upgrade - Setback from S.A.S. to foundation from 20' to 10'
3, Local regulation variance - Setback from S.A.S. to a wetland from 100' to 71'
This approval is also subject to the following conditions:
1. Prior to the issuance of the Disposal Works Installers Permit, the applicant must submit a
foundation as-built at the same scale as the approved plan.
2. Prior to the issuance of the Disposal Works Installer's Permit, the applicant must submit
the floor plans of the home showing no greater than four bedrooms or a total of nine rooms.

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 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.
