Enclosed are the results of pert tests on:
Ralph Joyce Lot B Forest p 8 1)and
Walter Joyce 595A Eoxford Street
Comments on Forest Street: Only Lot B was perced, Cart Young was out flagging
wetlands at 10 am when I first arrived. It is probable that a system on this lot will require
a variance for 100' from wetlands. A John Deere 41 OD backhoe was used, and was
unable to pick the boulders from the bottom of the pits(I believe that an excavator could
go down much deeper. Evidence of this is that only 30 feet or so away was an eight to ten
foot old foundation hole with the saute type of material). Thus on Test Fit 1, there was
not 4 feet of permeable material observed. A system designed on today's test trust be
conditioned on having an excavator go out next spring to verify a 4 foot permeble layer
and to look for mottles(none were observed in the shallow'Test Pit 1). Also only one
perc test was performed, so another pert will also have to be done in the spring.
Thanks,

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 321 . 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:
d before request for certificate of
7. Easement agreement will be file
compliance.
8. Slope of sewer line from building is 0.01
9. Profile is revised.
10. grading at septic tank has been revised
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 third review for Lot A and Lot B, Forest Street, Map 106A Lot 81,82,83
Dear Sandra,
Because the proposed leaching beds for both 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, I have
chosen to address both lots in one letter_
To the best of my determination, the plans dated February 17, 2000 have the following
revisions with regards to the plans that i approved in my report dated May 6, 1999:
• The building on Lot B was moved.
• A pump and pump chamber was added to Lot A
• The leaching bed elevations were lowered.
(I note that the lowering of the leaching bed elevations is satisfactory because it still
leaves a 4-foot separation between the bottom of the leaching beds and the ESHW
determined for the high point of the leaching bed.)
Lot A
I have the following concerns for Lot A:
• The leaching field must have a vent because of the proposed pump.
• The pump specification notes that normally are a part of a pump system are
missing on the plan(probably by mistake). Items usually addressed are:
Pump can pass 1 t/4" solids, pump controls, alarm, manual operating switch,
bleeder hole, etc.
• The volume of effluent to be pumped and the number of cycles per day are
missing. 310 CMR 2204R
® The"on" bulb switch for the pump is shown to be located only 3 inches
above the"off' bulb switch. It appears that this figure should be more like
18 inches if 440 gallons is to be pumped in one dose.

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.
Sincerely,
