Title V review for Loot A and Lot L3, Forest Street,Map 106A Lot 81,82,83
Dear Sandra,
Because the proposed leaching beds for bath lots are so close together, and the design
for both lots is shown on the plan and on the profile on both sets of designs, T have
chosen to address both lots in one letter.
Enclosed find the"Checklist for North Andover Septic System Flans" for the above-
mentioned site, The following is a list of all the 'Problem' areas and deficiencies Dort
Engineering has found.
* The use of the reserve areas will require both raising the septic tank and building
sewer, or will require a pump.
The bottom of the proposed leaching fields are at elevation 145.5' for Lot A, and
144.50' for Lot B. The highest existing grade for the two reserve areas is about
elevation 150'. If we assume the ESHW is down 36"below the ground surface,
then the bottom of the field to be built in the reserve area would be 151'. Almost
certainly, the use of the reserve would require a pump for bath Lots.
* As noted in General Note 10 on Sheet.3,the use of the reserve area would require
the construction of concrete retaining gall.
On my opinion the above two issues can be resolved if trenches are used in place of
fields. The use of trench design will allow the reserve areas to be between the
trenches. "Thus the reserve and the trenches to be built would be right next to each
other, and the elevations would therefore be the same for both,)
* There is more than 3' of fill over southerly half of the field on Lot B. 310 CMR
15.221(7).
As correctly shown on Section A-A, the fill required for the field on Lot A will fill over
PORT the held on Lot B by more than 3'.
("This can be partially addressed by the following observation. The elevation of the
N highest existing grade ofthe field on Lot A is about 147'. TF 98-12-1 is closest to this
IW high point, and if ESHW of 4' below the ground surface is used(as detennined by TP
98-12-1)then the elevation of ES for the highest grade for Lot A is 143'. Thus tine
C.ivir Kagineers& bottom of field for Lot A would be 4' higher or elevation 147', The proposed design
Latid Surveyortt has the bottom of field for Lot A to be 148.5'. Thus in my opinion it is possible to
One Harms 5trer-t lower the design elevations of the field on Lot A by 1.5'. This would keep the fill
PVewE,r0195u t' � spilling over the field on Lot B to less than ' depth.)
(978)265-8594

310 CMR 15.228(2).
Apr°-01 -99 06: 59A Paul D. Tuir-bide, PE/PL5 508-465-0313 P.03
® Benchmarks must beset within 50®75' of the leaching facility. 310 C 220(4)(q)
As noted in General Note 11,Benchmarks are proposed to be set prior to construction.
A condition of approval should be that the benchmark would be set as per said Note 11.
• The pipe connecting the ends of the distribution lines must be solid pipe. NA 15.01
• On Section A®A the stone to be placed under and around the distribution lines of the
field is incorrectly shown as" 8" of 1/8"—3/8"washed stone". It should be" 10"
of 3/4"— 1 '/a"washed stone". (Also the design calls for 4"of 1 18"to 3/8"washed
stone to be placed over the larger stone. The design regulations call for a thickness
of 2" rather than 4". however I see no problem with putting down 4" instead of 2".)
The following are problems that are for only one of the two lots.
LOT A
• The proposed leaching field for Lot A is to be built on Lot 13, with a"Grading and
Maintenance Easement" to be created. I could not find in the regulations any reason
why this cannot be done(the regulations only deal with shared systems). However
310 CMR 15.290(d)states in part a concern that"...each user ... has the legal
ability to accomplish any necessary maintenance, repair,or upgrade of the
component." Therefore I would suggest the following:
1. A copy of the proposed Grading and Maintenance Easement be forwarded to the
Board of health for review that 310 CMR 15,290(d)has been complied with.
2. A copy of the recorded easement once it has been recorded at the Registry of
Deeds(to be placed in the file).
3. A metes and bounds description should be created and a plan of the easement
with dimensioning should be recorded at the Registry of Deeds along with the
easement instrument.
• The grading shown on the plan around the septic tank for Lot A should be changed
to show that the final grade contour 152 should wrap around the tank(to have proper
cover as shown on the profile).
® For Lot A,the invert of the building sewer at the foundation should be raised to
elevation 151.25' (to maintain the minimum slope of 0,01 to the septic tank).
IL a A minor drafting error in the profile. The slope shown for the pipe running from the
foundation to the tank should be 0.01 and not 0.001.
If you have any questions or comments please feel free to contact me.

Re: ssds revisions lots A & B Forest St. for Ralph R. Joyce
Dear Ms. Starr:
We are in receipt of your letter dated April 16, 1999. In response to the issues
raised in said letter:
1. Trenches were considered but rejected due to area limitations for the
following reasons:
a. ) The break out requirements would require the trenches to start
approximately 30' from the southern lot line. The width of system including
reserve would be an additional 32' . With the required 10' separation for the
system on lot A, the total distance from the lot line would be approx. 72' to the
first trench on lot A. This would not leave enough area to the 100' wetland
setback for the system on lot B.
b. ) Nearly twice as much of the lot on the south side of the proposed
house on lot B would need to be cut and filled.
c. ) The higher water table in test pit 98-12-2 would require a pump
to be used in the primary system initially rather than added later should the
primary system fail,
2. The leach area on Lot B has been raised .88' to have maximum 3' of cover
3. Access covers are brought to within 6" of finish grade.
4. Benchmark is located in ridge on southeast side of leach areas.
5. Pipe connecting end of leach pipes has been specified.
6. Section A-A note has been changed.
Lot A Only:
7. Easement agreement will be filed before request for certificate of
compliance.
8. Slope of sewer line from building is 0.01
9. Profile is revised.
10. grading at septic tank has been revised

RE: Lots A& B Forest Street(Map 106A, 81, 82, 83)
Dear Mr. Christiansen:
This is to inform you of the approval status for the proposed septic systems on these two
lots.
Lot A still has the following technical deficiencies:
• The leach field is missing a vent(needed because of the proposed pump system).
• Pump specifications are missing.
• Volume of effluent to be pumped and the number of cycles per day area missing(3 10 CMR
15.22(04)R.
• The"on"switch for the pump is shown to be located only 3" above the"off" switch which
appears to be incorrect if 440 gallons are to be pumped in one dose.
The plans dated February 17,2000 are approved for a dwelling with a maximum of nine
rooms.
Please call the office at 978-688-9540 if you have any questions.

Re: SSDS revision lot A Forest St. for Ralph R. Joyce
Dear Ms. Starr:
We are in receipt of your letter dated May 1.8, 2000 in which you quote 15,241(4) stating the
vent is located incorrectly. The purpose of this vent is the venting of the pump not the leach field; it
has therefore been located at the highest point. Because the field does not exceed 50', it does not
require venting 15.251 (11), Locating the vent as designed relieves the pressure from the pump at the
d-box allowing for gravity feed of the leach field fi•om the d-box. Placing the vent at the end of the
leach field will cause the system to be pressurized all the way to the end of the distribution line, Flow
through the d-box will thus be pressurized. If you still feel we should relocate the vent, we will do so.
Please advise.
Should you have any further questions in the above matter, we are available at your
convenience and can be reached by phone at, 978-373-0310.

RE: 'Title V review for Lot A Forest Street, Map 106A Lot 81,82,83
Dear Sandra,
I previously had concerns about the proposed vent for Lot A Forest Street, My concern
was that if the vent is directly attached to the dbox then any jostling of the vent pipe
might torque the dbox out of level, affecting the distribution of effluent in the
distribution lines.
Phil Christiansen is the Professional Engineer who has stamped and signed the design
plans. He and I talked on the phone today. Phil stated that it is his professional opinion
that the vent can be constructer) such that it will not affect the dbox integrity. Based on
Phil's professional experience and opinion, I do not have any further concerns about the
vent pipe being connected directly to the dbox.
If you have any questions or comments please feel free to contact me.
