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).
