(A)   The purpose of this subchapter is to provide performance standards in the control of commercial and industrial uses in the town. These standards are designed to prevent health and safety hazards, public nuisances, and harmful effects upon the natural environment. They are also designed to permit potential industrial nuisances to be measured factually and objectively, and to ensure that all commercial and industrial uses will provide methods to protect the town from hazards which can be prevented by processes of control and elimination.

   (B)   If any standards are established by local or state building or fire codes, by local waste water or solid waste ordinances, by any department or agency of the State of Rhode Island or by any federal agency, which conflict with the standards specified in this subchapter, the more stringent or restrictive standards shall apply.

(Ord. passed 10-30-06)

   (A)   The provisions of this subchapter shall apply to any commercial or manufacturing use located anywhere within the town and shall also apply to any use established in any business or light industrial zoning district.

   (B)   Performance standards for any use or process operating in LI (Light Industry) District shall be measured at the zoning district boundary at a point nearest the use or process being measured. Performance standards for any use or process operating in any district other than LI shall be measured at the lot line at a point nearest the use or process being measured.

(Ord. passed 10-30-06)

   (A)   The administration of the performance standards herein set forth is charged to the Zoning Officer. Any proposed use or process, alteration or change to an existing use or process, or determination of compliance for an existing use or process, either as a permitted use or a nonconforming use, shall be reviewed by the Zoning Officer who shall determine compliance or noncompliance herewith.

   (B)   Subsequent to a study of the use, the Zoning Officer may determine that there are reasonable grounds to believe that the use may violate the performance standards set herein and may initiate an investigation.

(Ord. passed 10-30-06)

   (A)   Following the initiation of an investigation, the Zoning Officer may require the owner or operator of any proposed use to submit such data and evidence as is needed to make an objective determination. The evidence may include, but is not limited to, the following items:

      (1)   Plan of the existing or proposed construction and development;

      (2)   A description of the existing or proposed machinery, processes and products;

      (3)   Specifications for the mechanisms and technique used or proposed to be used in restricting the possible emission of any of the items referred to in §§ 2711 through 2718.

      (4)   Measurements of the amount or rate of emissions of the items referred to in §§ 2711 through 2718.

      (5)   Certification by a registered professional engineer that the proposed use or construction would comply with the requirements and standards for the regulation of commercial and industrial processes as set forth in this subchapter.

   (B)   Failure to submit data required by the Zoning Officer shall constitute ground for denying a certificate of zoning compliance for any use of land.

(Ord. passed 10-30-06)

   In the investigation of the compliance with the standards set forth in this subchapter by any existing or proposed use, the Zoning Officer may require the owner or operator of the existing use or the applicant for the proposed use to provide a study and report by an expert consultant as to the compliance or noncompliance with said standards of the existing or proposed use and advice as to how such existing or proposed use if not in compliance, can be brought into compliance with said standards.

(Ord. passed 10-30-06)

   Within 30 days following the receipt of the required evidence, or receipt of the reports of expert consultants, the Zoning Officer shall make a determination as to compliance, he shall authorize the issuance of any permits which may have been withheld pending said determination. The issuance of a permit for a proposed use shall not constitute compliance with the performance standards if, after construction and operation, there is evidence of noncompliance with such standards.

(Ord. passed 10-30-06)

   The Zoning Officer may require modifications or alterations in the existing or proposed construction or the operational procedures to insure that compliance with the performance standards will be maintained. The operator shall be given a reasonable length of time to effect any changes prescribed by the Zoning Officer for the purpose of securing compliance with the performance standards.

(Ord. passed 10-30-06)

   The Zoning Officer's action with respect to the performance standards procedures may be appealed to the Zoning Board of Review within 30 days following said action. In the absence of such appeal, the Zoning Officer's determination shall be final.

(Ord. passed 10-30-06)

   The Zoning Officer shall investigate any purported violation of performance standards and, for such investigation, may request that the Zoning Board employ qualified experts. If he finds that a violation occurred or exists, a copy of said findings shall be forwarded to the Town Solicitor. The services of any qualified experts, employed by the Zoning Officer to advise in establishing a violation, shall be paid by the violator if said violation is established, otherwise, it shall be paid by the town.

(Ord. passed 10-30-06)

   If, after the conclusion of time granted for compliance with the performance standards, the Zoning Officer finds the violation is still in existence, any permits previously issued shall be void and the operator shall be required to cease operation until the violation is remedied.
