SD 2.00 -
|
Construction, Renovation and/or Change of Use
of Structures Using Individual Sewage Disposal Systems
|
(a) No person shall begin any building construction,
building renovation and/or change of use of any structure from which
sewage is being or will have to be disposed of by means of an individual
sewage disposal system including improvements which will result in
increased sewage flow, without first obtaining the Director's written
approval in accordance with this section.
| |
I. CONSTRUCTION OF NEW STRUCTURES:
| |
Whenever an applicant proposes to construct
a new structure from which sewage will be disposed of by means of
an individual sewage disposal system, an Application for New System
shall be made in accordance with SD 2.01 (b)(1) and SD 2.02, below.
All Applications for New Systems shall conform with all requirements
under these regulations.
| |
(a) Construction of New Structures in Subdivisions
- No person shall begin construction of any new structure in a subdivision
located in an area where sewage will have to be disposed by means
of an ISDS until he/she has applied for and obtained a Certification
of Site Suitability from the Director in accordance with SD 18.00
et seq. An approved Certification of Site Suitability shall not operate
as an approval for the construction of any ISDS as required by SD
2.01.
| |
II. BUILDING RENOVATIONS AND CHANGES OF
USE TO EXISTING STRUCTURES:
| |
Whenever an applicant proposes any building
renovation or change of use (as defined in SD 1.00) of an existing
structure from which sewage is disposed of by means of an ISDS, an
Application for a System Suitability Determination shall be made.
For the purposes of this section, the term "building renovation" shall
also be defined as including any addition, replacement, demolition
and reconstruction, or modification of an existing structure on the
subject property which:
| |
(a) Results in an increase in sewage flow into
the system*; or
| |
(b) Affects fifty (50) percent or more of the
floor space of the existing structure; or
| |
(c) Is valued at greater than twenty-five (25)
percent of the current replacement value of the subject structure where the existing sewage disposal system is a cesspool. For the purposes of this section, current replacement value may
be established by using the BOCA cost index, or the owner may provide
the pre-renovation replacement value as established by a qualified
appraiser or estimator.**
| |
*NOTE: All sewage flows shall be
determined in conformance with State ISDS regulations.
| |
**NOTE: The Department recommends
that whenever an owner proposes a building renovation or change of
use of a structure using a cesspool-type or privy ISDS, that the owner
consider proceeding directly to an Application for Alteration under
SD 2.01(b)(2) rather than applying for a System Suitability Determination
(see SD 2.00 (a) (4) below).
| |
III. APPLICATION FOR SYSTEM SUITABILITY
DETERMINATION:
| |
An application for System Suitability Determination
shall be required as specified in SD 2.00 (a)(2), above, in order
to determine whether the existing individual sewage disposal system
is suitable for the purposes proposed by the applicant. In reviewing
any Application for system Suitability Determination, the Director
may consider the cumulative effects resulting from past Change of
Use Applications, Applications for System Suitability Determination,
building permits and/or deed restrictions relating to the subject
property. After reviewing an Application for System Suitability Determination,
the Director shall determine whether the existing system:
| |
(a) Is suitable to adequately dispose of the
proposed sewage flows so as to protect the public health and the environment;
or
| |
(b) Is unsuitable and requires an approved Application
for New System or Application for Alteration, in conformance with
SD 2.01 (b) (1) or 2.01 (b) (2), respectively, and SD 2.02 before
the proposed building renovation or change of use may be allowed.
| |
IV. SYSTEM SUITABILITY DETERMINATIONS
FOR STRUCTURES SERVED BY CESSPOOLS:
| |
Cesspools are defined by these regulations to
be a substandard method of sewage disposal. Accordingly, any Application
for System Suitability Determination relating to a structure serviced
by a cesspool which is filed for review with the Department pursuant
to SD 2.00 (a)(2) and (3), above, will be presumed to be unsuitable
and an application for New System or Alteration will be required in
accordance with SD 2.00 (a)(3)(B), above.
| |
(a) For System Suitability Determinations required
under SD 2.00 (a)(2)(C) only, the Department's presumption of unsuitability
may be rebutted by supplying the Department with affirmative engineering
and geohydrological data indicating that the cesspool functions adequately
to protect the public health, public interest and the environment
in accordance with these regulations.
| |
(b) In rebutting the Department's presumption
of unsuitability, the applicant shall be required to demonstrate the
following minimum criteria and setback requirements:
| |
(i) 75 feet to private well
| |
(ii) 200 feet to public well
| |
(iii) 3 feet separation between seasonal high
groundwater table and the bottom of stone under cesspool
| |
(iv) 200 feet to surface drinking water supply
or tributary stream or drain thereto
| |
(v) 150 feet to critical resource area as defined
in these regulations
| |
(vi) Fecal coliform measured in groundwater
within 50 feet of cesspool does not exceed an MPN of 10 per 100 ml
| |
(vii)No history of sewage overflow or other
septic system failure
| |
V. EXCEPTIONS TO REQUIREMENT FOR APPLICATION
FOR SYSTEM SUITABILITY DETERMINATION:
| |
No Application for System Suitability Determination
shall be required where a valid permit for New System or Alteration
exists at the time of the issuance of the building permit and the
ISDS design approved by said permit accounts for the proposed improvements
to be performed.
| |
(b) Issuance of Building Permits for Activities
Requiring Approval Under These Regulations - A municipality shall
not issue a building permit pursuant to R.I. General Laws, Chapter
23-27.3, as amended, unless all written approvals by the Director
required by these Regulations have been presented to the municipality
and said approvals are valid at the time of the issuance of the building
permit.
| |
