Dear Mr. Sullivan:
The proposed wastewater system design plans for the above site dated February 19, 2019. and
received on March 4, 2019 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

with General Use Certification and/or Approved Remedial Use (SCASAS II.X)regulation that is
not met by this design follows each item where applicable.
Sheet 1 of 2:
1. On proposed site plan, indicate the name of abutters from recent tax map (NA 3.2a.).
2. On proposed site plan, indicate the name of the record applicant, or if owner and
applicant, state as such(NA 3.2g.).
3. On proposed site plan, if appropriate, add the note:
I certify the locations, elevations and ties shown on this plan result from an actual survey
made on the ground.
Signature of Designer, Date (NA 3.2s.)
4. On proposed site plan, indicate the location and information about the additional test hole
where refusal was encountered and was deemed not usable (CMR 15.220 (4)(h)).
5. Provide a minimum of two deep observation hole tests in the presence of the Approving
Authority, or request a local upgrade Approval or variance(CMR 15.102 (2)).
6. On proposed site plan, existing grade at the center of TH-1 appears to be 97.5. The SOIL
DATA ofDTH-1 says the grade is 98.3. Clarify the discrepancy. (CMR 15.220 (4)(h)).
7. On proposed site plan, existing grade at the center of TH-2 appears to be 90.5. The SOIL
DATA of DTH-2 says the grade is 89.9. Clarify the discrepancy. (CMR 15.220 (4)(h)).

proposed contour 102 to ensure the top of septic tank grading is per regulation(CMR
15.228 (1)).
9. On proposed site plan, indicate surface drainage shall be directed away from the soil
absorption system (CMR 15.240 (11)).
Sheet 2 of 2:

minimum vertical separation distance between the bottom of the...soil absorption system
above the high ground-water elevation shall be four feet..." or request a Local Upgrade
Approval or variance. (CMR 15.212 (1)(a)).
2. On System Profile detail, confirm the graphic elevations of the proposed top and bottom
