Hi Amy,
1. Page 1, A note from HD indicating system may be different than the As-Built.
2. Page 2, is the most recent T-5, done in 2010. We assume this is correct. It's different
from the As-Built. It looks like the T-5 inspector made some changes regarding distances.
3. Page 3, Table 1, Setback distances.
4. Page 4 & 5, Local Regulation information:
CMR 310:15.228 (3)
CMR 310:15.240 (7)&(10)
5. Page 6, State Regulation information.
CMR 310.15.211
At any point you may need to access any one of these components. Ie: Pipes, Tank, D-box,
Field. Its never in ones best interest to place a permanent structure on top of components.
Here's some good information to review,
Please call with any questions. If I'm not available, please speak to Sue Sawyer.

(2) The minimum separation between inlet and outlet tees shall be no less than the liquid depth
of the septic tank and shall be the longest direction (which shall not include the diagonal
distance)across the tank in plan view.
(3) Inlet and outlet tees to rectangular tanks shall be set in the end walls or into a side wall
within 12 inches of the end wall.For circular tanks, the inlet and,outlet tees shall be set and
stabilized on opposite ends of a diameter of the tank.
(4) There shall be an air space of at least three inches between the tags of the tees and the inside
of the tank cover, The tops of the tees shall be left open to provide ventilation or separate
ventilation shall be provided. All outlet tees shall be equipped with a gas baffle or a Department
-approved effluent tee filter.
(5) The inlet pipe elevation shall be no less than two inches nor more than three inches above
the invert elevation of the outlet pipe. The inlet and outlet invert elevations shall be at least 12
inches above the high groundwater elevation. If high groundwater(redoximorphic features)is
determined by soil evaluation in accordance with 310 CMR 15.100 through 15.107 at the
proposed location of the septic tank,the Approving Authority may reduce the 12 inch required
separation,but in no cases shall it be reduced to less than one inch above high groundwater as
determined by redoximorphic features.
(6) The inlet tee shall extend a minimum of ten inches below the flow line. The outlet shall be
provided with a tee extending below the flow line in accordance with the following table;
Liquid Depth in Septic Tank Depth of Outlet Tee below Flow Line
4 feet 14 inches
5 feet 19 inches
6 feet 241nches
7 feet 29 inches
8 feet 34 inches
(7) Effluent tee filters may be installed in lieti of outlet tees provided that they are installed in
accordance with the manufacturer's specifications,include an appropriate outlet cover at grade,
and are inspected and cleaned at least on an annual basis.
•..
15.228: Placement and Accessibility of Septic Tank
(1) Septic tanks shall be installed level and true to grade on a level stable base that has been
mechanically.compacted and on to which six inches of crushed stone has been placed to
minimize uneven settling.If the septic tank is'placed in fill,proper compaction is required to
ensure stability and to prevent settling. Septic tanks shall have a minimum cover of nine inches.
Systems buried greater than nine inches below grade trust be equipped with risers on all tank top
openings and the distribution box,
(2) At least three manholes with readily removable impermeable covers of durable material
shall be provided. The manholes over the inlet and outlet tees shall have a minimum opening
of 20 inches and the center manhole shall have a minimum opening of eight inches. By
July 1,2007,manufacturers of fiberglass and polyethylene tanks shall comply with the center
hole requirement.Access ports shall be placed at the center and over each inlet and outlet tee.
For compartmental tanks, the center manhole shall be placed as access to the compartment
connection. Inlet and outlet tees shall be made accessible for inspection and maintenance by
providing precast concrete or equivalent watertight risers(with steps where appropriate)with
covers over the access ports to within six inches of finish grade for system designs in excess of
1,000 gpd. For system designs of 1,000 gpd or less,at least one access port shall be accessible
within six inches of final grade. Manholes brought to final grade shall be secured to prevent
unauthorized access.
(3) Septic tanks shall be accessible for inspection and maintenance.No structures shall be
located directly upon or above the septic tank access locations which interfere with performance,
access,inspection,pumping,or repair.

(2) Effluent from any component of an on-site sewage disposal system shall not be disposed
of by direct discharge to any waters of the Commonwealth,unless in compliance with a permit
issued pursuant to 314 CMR 3,00(surface water permitting)or 314 CMR 5.00(groundwater
permitting).
(3) Soil absorption systems shall be designed as an integral part of the system. Septic tank
effluent is to be distributed throughout the soil absorption system by means of effluent
distribution lines so that the effluent can migrate through the underlying soil column under
unsaturated flow conditions,All soil absorption systems shall achieve the following objectives
of the soil treatment process:
(a) maximum stabilization of organic wastes in the effluent;
(b) removal of pathogenic organisms,nutrients,and particulates;
(c) recharge of the ground-water table with adequately treated effluent with minimal
attendant pollution of the groundwater;and
(d) disposal of the effluent without discharge to the ground surface or the creation of any
nuisance.
(4) The minimum area for the design of a soil absorption system shall be determined by the
results of the site evaluation set forth in 310 CMR 15,100 through 15,107 and in accordance with
the appropriate long-term acceptance rate eriteri a specified in 310 CMR 15,242(effluent loading
rates), Area requirements increase by 50%when garbage grinders are installed and the system
shall be upgraded to meet such requirements prior to the installation of a garbage grinder.
(5) All soil absorption systems designed to serve single family dwellings,including but not
limited to single family condominiums and cooperatives,shall be designed to serve a minimum
of three bedrooms,unless a deed restriction limiting use to two bedrooms is granted to the local
Approving Authority,
-° , (6) Absorption trenches should be used whenever possible.
V �r (7) No driveway,parking or turning area or other impervious area shall be located above a soil
absorption system,except where restrictions on the use of the land make it unavoidable.In such
cases,the soil absorption system shall be vented to the atmosphere in accordance with 310 CMR
15.241.
(8) The bottom of each soil absorption system shall be excavated to a level grade,If the removal
of stones or boulders is required, creating localized depressions, filling to grade with the
excavated naturally occurring pervious soil or material in compliance with 310 CMR 15.255 is
acceptable,
(9) The soil placed as backfill over the soil absorption system shall be a minimum of nine
inches,excluding topsoil,placed in Jifts and sufficiently compacted to prevent depressions due
to settling which may intercept or collect surface water runoff above the system, Backfill must
be clean and free of stones and boulders greater than six inches in size. Tailings,clay or similar
materials are prohibited.
(10) Final cover above the system shall be stabilized and graded to reduce infiltration of surface
water and minimize erosion. Finish grade shall have a minimum slope of 0,02 feet per foot,
(11) Surface drainage shall be directed away from the soil absorption system,
(12) For systems with a design flow of 2,000 gpd or greater,the separation distance to the high
groundwater elevation required by 310 CMR 15.212 shall be determined by adding the effect of
groundwater mounding to the high groundwater elevation as determined pursuant to 310 CMR
15.103(3).

15.204: Increases in Design Flow to System
No person shall increase the actual or design flow to any cesspool or to any other system above
the existing approved capacity,or change the type of establishment of a facility served by a cesspool,
unless the cesspool or system is upgraded first. Upgrades to accept increased design flow shall be
performed in full compliance with the requirements applicable to new construction unless a variance
is allowed pursuant to 310 CMR 15.414. For purposes of 310 CMR 15.204,the approved design flow
shall be the flow listed in the most recent Disposal Works Construction Permit.
15.211: Minimum Setback Distances
(1) All systems must conform to the minimum setback distance for septic tanks,holding tanks,pump
