Re: Subsurface Sewage Disposal System Plan for 597 Foster Street (Map 104B, Lot 50)
Dear Mr. Berry:
The proposed wastewater system design plan for the above site dated August 10, 2020 and
received on August 12, 2020 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 where applicable.
1. Soil evaluation forms 11 & 12 must be submitted with the plan and the plan should
contain the location of all test pits and percolation tests (310 CMR 15.220(4)(i)).
2. Change the soil descriptors to match the soil testing field notes.
3. Specify the horizons of soil to be removed and replaced with sand fill.
4. Provide a statement identifying whether the property is within or not within Watershed of
Lake Cochichewick(NA 3.2).
5. The following statement is required(per NA 3.2): "I certify the locations, elevations and
ties shown on this plan result from an actual survey made on the ground".
6. A Local Upgrade Approval request form must be submitted if seeking relief from design
standards in Title 5 (310 CMR 15.403(1)).
7. Clarify whether the design is or is not accommodating a garbage grinder. There are
conflicting notes regarding this on sheets 1, 2 & 3. If plan does specify a garbage disposal
the field must be 50% larger(310 CMR 15.240(4)) . Additionally, if plan does specify a
disposal, there must be 2 tanks in series or a 2 compartment tank(310 CMR
15.223(1)(c)).
8. Notate the building sewer will be laid on a compact, firm base and in a straight line(310
CMR 15.222(5) & 222(7)).
9. The effluent filter brand must have an annual filter maintenance specified(310 CMR
15.227(7)).

10. A minimum of 2 deep observation holes are required in the primary disposal area(310
CMR 15.102(2)).
11. Notate the top of the distribution box chamber<= 36"below grade (310 CMR
15.221(7)).
12. Notate that the leach pipes will have 3/8"—5/8"orifices (310 CMR 15.251(8)).
13. Ends of the distribution lines shall have ends capped or connected together by
unperforated pipe of the same materials specifications (310 CMR 15.251(9)).
14. Clarify the cross section and profile on sheet S4 which indicates no water table was found
as the basis of the design where other design notes indicate water table was found
