A. 
Grease, oil and/or sand interceptors or retainers shall be installed by the industrial user at its own expense when, in the opinion of the JRSB, such are necessary for the proper handling of liquid wastes containing grease, oils and/or sand in excessive amounts and/or any flammable wastes and/or such other harmful ingredients. Such interceptors shall be of a type and capacity approved by the JRSB and shall be located as to be readily and easily accessible for cleaning by industrial users and/or for inspection by the JRSB.
B. 
Where installed, all grease, oil and/or sand interceptors shall be maintained by the industrial user at its own expense and shall be kept in continuous and efficient operation at all times.
C. 
Prior to the JRSB approving any industrial source, the admission of any materials into its sewers as set forth in § 137-26B of this law, the JRSB shall direct the industrial user causing admission of any such materials to construct, install and operate, at its own expense, such preliminary treatment plants and/or facilities as may be required in order to:
(1) 
Reduce the BOD to 300 parts per million and the SS to 350 parts per million by weight.
(2) 
Reduce objectionable characteristics or constituents to within the maximum limits provided for in § 137-26B and/or 137-27 of this law.
(3) 
Control the quantities and rates of discharge of such waters or wastes.
D. 
No preliminary treatment plant and/or facility shall be constructed or operated unless all plans, specifications, technical operating data and/or other information pertinent to its proposed operation and/or maintenance shall conform to all JRSB, EPA and New York State Department of Environmental Conservation standards.
E. 
All such preliminary treatment facilities as required by the law shall be maintained continuously in satisfactory and effective operating condition by the industrial user or person operating and maintaining the facility served thereby and at the industrial user's sole expense.
F. 
No provision contained in the law shall be construed to prevent or prohibit a separate or special contract or agreement between the JRSB and any industrial user whereby industrial waste and/or material of unusual strength, character or composition may be accepted by the POTW for treatment subject to additional payment therefor by the industrial user; provided, however, that such contract or agreement shall have the prior approval and that such contract will require compliance with pretreatment standards.
G. 
The participating members and/or the JRSB reserve the right to reject admission to the system or otherwise deny or condition any new or increased loadings of any waste harmful to the POTW or to the receiving stream.
H. 
Industrial users shall provide necessary wastewater treatment as required to comply with this law and shall achieve compliance with all pretreatment standards within the time limitations as specified by the national pretreatment regulations. Any facilities required to pretreat wastewater to a level acceptable to the JRSB shall be provided, operated and maintained at the industrial user's sole expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the JRSB for review and shall be acceptable to the JRSB before construction of the facility. The review of such plans and operating procedures will in no way relieve the industrial user from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the JRSB under the provisions of this law. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and must be acceptable to the JRSB prior to the industrial user's initiation of the changes. The JRSB shall annually publish in the official newspaper of the municipality a list of the industrial users which were in significant noncompliance with pretreatment standards during the 12 months. The notification shall also summarize any enforcement actions taken against the industrial users during the same 12 months. All records relating to compliance with pretreatment standards shall be made available to officials of the EPA or approval authority upon request.
