In accepting an application for a special use permit for the initiation of a manufacturing use in a Limited Manufacturing District as provided in §
185-8N, the Zoning Board of Review will require the submission of affidavits or other supportive evidence that the applicant will observe appropriate standards of performance as set forth in this article. In granting such a special use permit, the Board will require that said standards be observed, and any noncompliance with these standards will be considered a violation of this chapter as set forth in §
185-44. Moreover, these standards shall apply to any manufacturing or business use taking place in any district.
Smoke and other airborne emissions of manufacturing
or business enterprises shall conform to the standards of the Air
Pollution Control Regulations of the Rhode Island Department of Environmental
Management, issued under the authority of Chapter 23-25 of the General
Laws of Rhode Island, 1956, as amended. Said regulations are hereby
incorporated as part of this chapter.
All manufacturing or business enterprises shall
be connected to the sewer system of the Town of Barrington, and no
discharge of liquid waste other than surface water runoff shall be
permitted into any septic tank, leach field, stream, wetland or other
water body. The Zoning Board of Review will require certification
from the Department of Public Works of the Town of Barrington that
the liquid waste discharged by any manufacturing or business enterprise
conforms to the standards set by the Town of Barrington. If deemed
necessary by the Department of Public Works, the Zoning Board of Review
may require the pretreatment of liquid waste prior to discharge into
the sewer system, or may require that such liquid waste be transported
to a suitable treatment or disposal facility in a manner conforming
to all applicable federal and state regulations.
No manufacturing or business enterprise shall
cause radiation emission which exceeds the safe limits established
in the regulations of the United States Nuclear Regulatory Commission,
or any other agency of competent jurisdiction. This limit shall apply
to emissions from radioactive materials and waste, electromagnetic
radiation, x-ray radiation, microwave radiation and other forms of
radiation presenting a potential hazard to employees and abutters
of the manufacturing or business enterprise.
No manufacturing or business enterprise shall
emit heat and/or glare, other than that associated with illumination,
which can be recorded at the property line of the manufacturing use.
Any exterior illumination of the building or site shall be oriented
so that it reflects light away from any public street or Residence
District.
No manufacturing or business enterprise shall
generate vibration which is discernible to the human sense of feeling
at the property line of the use for a cumulative total of three minutes
or more duration in any single hour between 7:00 a.m. and 7:00 p.m.,
or 30 seconds or more duration between 7:00 p.m. and 7:00 a.m. No
vibration shall produce an acceleration of more than 0.1 g or result
in a combination of amplitudes and frequencies beyond the safe range
of Table 7, U.S. Bureau of Mines Bulletin 442. The methods and equations
of said Bulletin 442 shall be used in enforcing this regulation.
No manufacturing or business enterprise shall
emit noise which, at the nearest Residence District boundary, is objectionable
due to beat frequency, shrillness or intermittence. Measurement of
noise shall be made at said Residence District boundary line by use
of an octave band analyzer calibrated in the preferred frequencies
(American Standards Association s1 6-190, Preferred Frequencies for
Acoustical Measurement).
A. The maximum permissible sound levels measured between
7:00 a.m. and 7:00 p.m. by this method shall be as follows:
