local Board of Health to determine the form they use.
Form 9A is to be submitted to the Local Board of Health for the upgrade of a failed or nonconforming
septic system with a design flow of less than 10,000 gpd, where full compliance, as defined in 310 CMR
15.404(1), is not feasible.
System upgrades that cannot be performed in accordance with 310 CMR 15.404 and 15.405, or in full
compliance with the requirements of 310 CMR 15.000, require a variance pursuant to 310 CMR 15.410
through 15.415,
NOTE: Local upgrade approval shall not be granted for an upgrade proposal that includes the addition of
a new design flow to a cesspool or privy, or the addition of a new design flow above the existing approved
capacity of an on-site system constructed in accordance with either the 1978 Code or 310 CMR 15.000.

❑ Use of a sieve analysis as a substitute for a perc test
❑ Other requirements of 310 CMR 15.000 that cannot be met—describe and specify sections of the
Code:
If the proposed upgrade involves a reduction in the required separation between the bottom of the soil
absorption system and the high groundwater elevation, an Approved Soil Evaluator must determine the
high groundwater elevation pursuant to 310 CMR 15.405(1)(h)(1). The soil evaluator must be a
member or agent of the local approving authority.

allowed for alternative systems approved in accordance with 310 CMR 15,284.
6. For new construction or an upgrade, the applicant can size the System in bed or

7. When the System is used with a secondary treatment unit approved in accordance
with 310 CMR 15.284 or 15.288, additional reductions in soil absorption system
may be allowed. In these situations the reduction in the SAS cannot exceed the
maximum allowed under the secondary treatment units approval. In no instance
shall the reduction in the soil absorption system area required in 310 CMR 15.242
exceed the maximum reduction allowed for alternative systems approved in
accordance with 310 CMR 15.284.
II. Special Conditions
1. The System is an approved Alternative Chamber for use as an Alternative Soil
Absorption System. In addition to the Special Conditions contained in this
Approval, the System shall comply with the "Standard Conditions for Alternative
SAS with General Use Certification and/or Approved far Remedial Use" (the
'Standard Conditions'), except where stated otherwise in these Special
Conditions,

Approval for General Use—February 19,2015
2. New Construction This Certification is for the installation of a System to serve
new construction or an existing facility with a proposed increase in flow, for
which a site evaluation in compliance with 310 CMR 15.000 has been approved
by the Approving Authority and the site meets the siting requirements for new
construction, as provided in Paragraph 6 in section 11 Design and Installation
Requirements of the Standard Conditions.
3. Remedial Site This General Use Certification also applies to the installation of a
System for the upgrade or replacement of an existing failed or nonconforming
system, provided that the facility meets the siting requirements for upgrades, as
provided in Paragraph 7 in section 11 Design and Installation Requirements of the
Standard Conditions
4. The System shall be exempt from the minimum inlet spacing requirements of 310
CMR15.253.
5. The System shall have a minimum of one inspection port through the top of one
of the chambers. The inspection port shall be capped with a screw type cap and
accessible to within three inches of finish grade.
6. When the System is installed in trench configuration, then the system shall
comply with these requirements:
a) Length(each trench) 100 feet maximum(3 10 CMR 15.251(1)(a));
b) Width (each trench)2 feet minimum to 3 feet maximum (3 10 CMR
15.251(1)(b)). - Chambers greater than 3 feet wide, when specifically
approved, are subject to other Special Conditions and limitations;
c) The minimum separation distance between any two trenches shall be two
times the effective width or depth of each trench, whichever is greater, or
where the area between trenches is designated as reserve area, three times the
effective width or depth of each trench, whichever is greater(3 10 CMR
15.25 1(1)(d));
d) The effective leaching area shall be calculated using the bottom area and a
maximum of two feet(per side) of side wall area for each trench (3 10 CMR
15.251(1)(e));
e) Trenches shall be situated, where possible, with their long dimension
perpendicular to the slope of the natural soil, Where possible they shall follow
the contour lines (3 10 CMR 15,25](2));
f) Trenches constructed at different elevations shall be designed to prevent
effluent from the higher trench(es) flowing into the lower trench(cs) (3 10
CMR 15,251(3));
g) The area between trenches may be designated as system reserve area only
where the separation distance between the excavation sidewalls of the primary
trenches is at least three times the effective width or depth of each trench,
whichever is greater (3 10 CMR 15,251(4)) - Chambers greater than 3 feet
wide, when specifically approved, shall be separated by three times the actual
width and are subject to other Special Conditions and limitations; and

h) Effluent distribution lines exceeding 50 feet in length shall be connected and
venting provided in accordance with 310 CMR 15.241 (3 10 CMR
15.251(11)).
7. When installed in trench configuration, approved Alternative Chambers greater
than 3 feet wide:
a) shall be installed with a minimum separation distance between any two
trenches of two tunes the actual width of the chamber, or where the area
between trenches is designated as reserve area, three times the actual width of
the chamber; and
b) shall only be entitled to a maximum effective width of 3 feet for the purposes
of calculating total effective leaching area.
8. When installed in a bed or field configuration, the System may be installed
without distribution piping, but must comply with the following requirements in
310 CMR 15.252:
a) the use of leaching beds or fields is restricted to systems with a calculated
design flow of less than 5,000 gpd per leaching bed or field(3 10 CMR
15.252(1));
b) the maximum length of chambers in series shall be 100 feet(3 10 CMR
15.252(2)(b));
c) separation distance between adjacent beds/fields shall be ten feet(3 10 CMR
15.252(2)(f)); and
d) the effective leaching area shall include only the bottom area, not the
sidewalls (3 10 CMR 15.252(2)(1)),
9. For Systems constructed in fill and installed, the System shall be installed as
specified in 310 CMR 15.255 Construction in Fill, except the minimum. 15 foot
horizontal separation distance to be provided between the soil absorption area and
the adjacent side slope shall be measured horizontally from the top of the
chamber.
10. The System is exempt from 310 CMR 15.287, specifically items: (5) requiring
written notification of alternative system prior to property transfer, (6) need for a
certified operator, (9) need for an operation and maintenance contract with an
