Re: 2198 Turnpike St. Subsurface Sewage Disposal System Plan (Map 108C Lot 6)
Dear Mr. LaGrasse
In response to the comments noted in your letter of July 20, 2017 we are submitting
revised plans dated August 2, 2017. We have addressed your comments as follows:
1. A Local Upgrade Approval request is required for only test pit within the proposed
disposal system area (3 10 CMR 15.404(1)(10.
I have enclosed the L UA request,
1 A Title 5 variance request is required to have no percolation test within the proposed
disposal system area (3.10 CMR 15.104(4)),
I have enclosed the variance request
3. A note or chart is required to be on the design plan listing all variances and Local
Upgrade Approvals (NA 3.2).
A note has been added to the design plan
4. Please submit the Local Upgrade Approval request form 9A with the revised plan.
The LUA request is enclosed
5. On sheet I oft, the site plan view does not depict the proposed finish grading as shown
on the profile view. Also make sure the proposed finish grading meets the breakout
requirement for all trenches. The current existing grading does not meet the breakout
reciuirement for trenches#I and42.
I have added finish grading to the site plan.
Also I have re-evaluated the elevation oj'seasonal high ground water beneath the
proposed trenches. Iplotted a seasonal high ground water elevation line between test pits
6 and 7. This plot resulted in the revised seasonal high water elevations shown on sheet
2. These revised elevations allowed me to lower the system by 0.78 fEet and as a result
the system is no longer a mounded system.
6. Indicate on the design plan any Natural Heritage & Endangered Species Program mapped
areas (INA 3.2). Mass GIS maps indicate an area in close proximity to the proposed
disposal system.
The Natural Heritage and Endangered Species Line has been added to the plan.
7. Since the Infiltrator Chamber system is proposed as an alternative soil absorption system
the "Standard Conditions for Alternative Soil Absorption Systems with General Use
Certification and/or Approved for Remedial Use"will apply. Please provide the
following as required by the approval conditions Section HO 8):
- proof that the Designer has satisfactorily completed any required training by
the CompanYjbr the design and inswIlation of the Technology;
No specific training is required by the dcsigner for the design of this lechnoloD
- Certification by the Designer that the design conforms to the Approval, any
Company Design Guidance, and 310 CMR, 15,000; and
A note hay been added to the design plan
a certification, signed by the Owner of record for the propertv to be served by
the Technology, stating that the property Owner:
1. has been provided a copy of the Title 5 11A technology y Approval,
the Owner's Manual, and the Operation and Maintenance Manual,
and the Own,-,j, (-jai-pp.v to Pnnin1v with all for and rondifinne.,
A certification by the owner is enclosed
2. for Systems installed under a Remedial Tse Approval, the owner
