Application for Local Upgrade Approval
Title 5, 310 CMR 15.000
DEP approved form required by 310 CMR 15.403(1)
To be submitted to Local Approving Authority/Board of Health: For the upgrade of a
failed or non-conforming system with a design flow of<10,000 gpd, where full
compliance, as defined in 310•CMR 15.404(1), is not feasible.
To be submitted to DER For the upgrade of a failed or non-conforming system with a
design flow of 10,000 up to 15,000 gpd and/or for upgrade of state of federal facility,
where full compliance, as defined in 310 CMF 15.404(1),is not feasible.
NOTE: Local upgrade approval shall not be granted for an upgrade proposal that
includes the addition of new design flow to a cesspool or privy or the addition of new
design flow above the existing approved capacity of a system constructed in accordance
with either the 1978 Code or 310 CMR 15 1000.

variance pursuant to 310 CMR 15.410-15.417.
7) If the proposed upgrade involves a reduction in the required separation between
the bottom of the soil absorption system and the high groundwater elevation, an
Approved Soil Evaluator must determine the high ground water elevation
pursuant to 310 CMR 15.405(1)(1)(1). The evaluator must be a member or agent

No application for upgrade approval in which the setback from property lines or a
private water supply well is reduced shall be complete until the applicant has
notified all abutters whose property 9or well is affected by certified at least ten
days before the Board of Health meeting at which the upgrade approval will be on
the agenda. Such notice shall include the date,time and place where the upgrade
approval will be discussed.
If the department is the approving authority,then such notice to abutters must be
completed prior to the date of submission of the application to the department.

Dear Members of the Board,
Please be advised that Noonan&,McDowell, Inc. has reviewed the plan dated 12/4/01,
by Merrimack Engineering Services. It is our opinion that the proposed design will meet the
requirements of Title 5 and the North.Andover Board of Health`By-Laws" if the following is
addressed:
Relocate D-Box to ensure that distribution pipes can be set level for first 2 ft. 232(3)(6)
Provide a beginning of leaching pipe elevation on profile (96.38).
3.) Minimum grades over system are
° Septic Tank- 99.1
D-Box - 98.2
Beginning of Field - 979
End of Field—97.7 �
Please revise grading as necessary.
4.) Revise location of 96 contour on south side for breakout compliance (96.9).
5.) The profile is not drawn to scale and cannot be checked.
6.) List of upgrades needs to be relabeled as Title 5 variance requests. Some of which can be
handled by the Board of Health as a Variance ie item 3 and others 1 and 2 will require D.
E. P. approval. 15.403

RE: 45 Hollow Tree Lane
Upgrade Plan of Subsurface Disposal System
Dear Ms. Starr:
We are in receipt of a review letter from Noonan & McDowell, Inc. dated January 16, 2002
for the above referenced project.
Enclosed herewith are three (3) copies of a revised plan and a septic plan submittal form
dated February 1, 2002.
With regards to the eight(8) items contained in the review letter, we offer the following
comments:
1. The D-Box has been drawn to scale to demonstrate that (2) feet: does exist.
between the beginning of the leach field and the D-Box although we do not
agree with the reviewer nor can we find any provision in Title 5 or the North
Andover Regulations which require the I" two level feet to be solid pipe
separated from the soil absorption system. 15.232(3) simply states "outlet
distribution lines shall be level for a minimum of their first two feet of length",
If the reviewer's interpretation were correct then butterfly type systems or
system with the D-Box located in the center of the SAS which distribute in
opposite directions would be prohibited and would not exist.
2. The beginning of the leaching pipe elevation has been provided on the plan.
1 These minimum grades, as determined by the reviewer, are met. Title 5,
15.240 (9,10 and 11) requires 9 inches of soil backfill excluding loam and a
minimum slope of 2% to direct surface drainage away from the system. These
requirements are met.
Mr. Sandra Starr, Director of Public Health
February 2, 2002
Page 2
4. In order to meet breakout requirements on the southerly (driveway) side of the
SAS the 96 contour is required to be 17.7 feet from the edge of the leach field.
This requirement is met.
5. All systems inverts, pipe lengths and slopes and finish grades can be easily
determined by the profile as shown and demonstrated by the reviewer's
comment#3, as such, we feel the plan adequately provides any installer the
necessary information to properly install the system and question what
information the reviewer needs to properly check the design for compliance
with Title 5. We request a waiver from the North Andover Regulations
regarding the scale of the profile.
6. We disagree with the reviewer and feel these items are clearly local upgrade
approvals pursuant to Title 5 Sec. 15.403.
7. Plan note#15 mares a statement with regards to existing wells within 150' as
required by 15.220 (4)K(3).
&. Again we disagree with the reviewer in that the distribution lines should be 2.5
feet from the end of the system as they are 2.5 feet from the sides, however, we
have revised the plan accordingly and provide a note with regards to
connecting and upturning the distribution line ends.
We feel, the system as revised, meets the requirements of Title 5 and the North. Andover
Board of Health and ask that the design be approved as re-submitted.
Very truly yours,

Dear Members of the Board,
Please be advised that Noonan& McDowell, Inc. has reviewed the plan dated 12/4/01 and
revised 1/16/02, by Merrimack Engineering Services. It is our opinion that the proposed design
will meet the requirements of Title 5 and the North Andover Board of Health"By-Laws" if the
following is addressed:
1) Provide proposed spot grades over septic tank.
2) A wavier is requested for profile not drawn to scale. I believe this should not be granted.
The purpose of a scale is to ensure that vertical and horizontal elements of the design are
complied with. If no scale is used the lines shown provide the allusion of compliance which
may not exist.
3) The upgrade wavier request for items 1 and 2 should be considered only if it is not possible to
adhere with the regulations. Also what is the mitigating environmental protection provided
to allow for a setback reduction.
4) Items in 220(4)(k) 1 & 2 are not disclosed as to their existence or not.
Respectfully,
John L. Noonan, P.L.S.-P.E.

Re: 45 Hollow Tree Lane
Dear Mr. Dufresne:
This is to notify you that the proposed plans dated 12/4/01 and revised 1/31/02 for the repair of the septic
system at 45 Hollow Tree Lane,North Andover have been approved with the following variances:
1. Distance fi•om the SAS to foundation, from 20' 15'.
2. Distance from septic tank to foundation, from 10' to 7'.
3. Vertical offset/separation from the bottom of the SAS to groundwater, from 5' to 4'.
4. Distance of septic tank to wetland,fi°om 75'to 51'.
5. Distance of SAS to wetland,from 100' to 51'.
6. Distance from the SAS to street drain from 50'to 32',
7. Waiver of scaled profile plan.
The homeowner should he made aware that with the high number of variances,and particularly variance number
3,that no additional rooms may be added on to the dwelling until such time as the house is connected to a
functioning sewer system. With this design the septic system is as large as it can be.
In addition,as the engineer,you should note that variance number 7—waiver of scaled plan- will not be granted
again.
If you have any questions, please call the office at 978-688-9540.
Sincerely,
Sandra Starr, R.S., C.H.O.
