The user shall provide necessary wastewater treatment as required to comply with the provisions of this chapter, any applicable federal categorical pretreatment standards, and all other applicable federal, state and local pretreatment standards within the time limitations as specified by the applicable pretreatment standards, whichever is more stringent. All facilities required to pretreat wastewater to an applicable level acceptable to the town shall be provided, operated and maintained at the user's expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the Village Board for review and shall be approved by the engineer of record, subject to the requirements of applicable codes, ordinances and laws, prior to construction of the facility. The approval of such plans and operating procedures will in no way relieve the user from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the town under the provisions of this chapter. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and approved by the engineer of record prior to the user's initiation of the changes.
A. 
Whenever deemed necessary, the engineer of record may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial wastestreams and such other conditions as may be necessary to protect the sanitary sewer facilities and determine the user's compliance with the requirements of this chapter.
B. 
The engineer of record may require any person discharging into the sanitary sewer facilities to install and maintain, on his/her property and at his/her expense, a suitable storage and flow-control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization.
C. 
Grease, oil and sand interceptors shall be provided, replaced and maintained by industrial or commercial users as required by the engineer of record and shall service all discharges containing sand, fats, grease or oils. All interceptors shall be sized in accordance with the specific sizing criteria established by the manufacturer, based on calculated loads. The installation of the unit must be installed in accordance with the applicable plumbing codes and standards. All required units must be approved by the Village, and, where applicable, Plumbing and Drainage Institute (PDI) certified units shall be used. A food waste grinder is not permitted to discharge into a grease interceptor unless the interceptor has been designed or rated for such an application, or unless a solids interceptor has also been installed upstream. The units shall be so located to be easily accessible for cleaning, inspection and sampling. Such interceptors shall be inspected, cleaned and repaired regularly, by the user at his/her expense, to the satisfaction of the Village. If, in the opinion of the engineer of record, any existing interceptor units are undersized, inadequate or in need of repair, the engineer of record can order the industrial or commercial user to replace that existing unit with a new interceptor meeting the Village's requirements.
D. 
Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
At least once every two years, the engineer of record shall evaluate whether each significant industrial user needs an accidental discharge/slug control plan. The engineer of record may require any user to develop, submit for approval, and implement such a plan. Alternatively, the engineer of record may develop such a plan for any user. An accidental discharge/slug control plan shall address, at a minimum, the following:
A. 
Description of discharge practices, including nonroutine batch discharges.
B. 
Description of stored chemicals.
C. 
Procedures for immediately notifying the engineer of record of any accidental or slug discharge, as required by § 81-36 of this chapter.
D. 
Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include but are not limited to inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents and/or measures and equipment for emergency response.
