At minimum, all permitted non-residential users are required to develop and implement an accidental discharge/slug control plan hereafter referred to a spill plan. At least once every two (2) years the pretreatment coordinator shall evaluate whether each significant industrial user needs a revision to its spill plan. The pretreatment coordinator may require any user to submit such spill plan or require modification of an existing spill plan based on changes that have occurred at the site or in response to an incident that had the potential to impact the POTW. In alternate years, the pretreatment coordinator shall evaluate whether each non-significant regulated user is required to file a revision to its spill plan based on changes that have occurred at the site or in response to an incident that had the potential to impact the POTW. Review of such plans and operating procedures by the village engineer shall not relieve the user from the responsibility to modify the user's facility or spill plan as necessary to meet all requirements of this chapter. Review by the village does not constitute an approval of a spill plan and the village and its designee(s) are not to be construed as responsible for the actions of the user and any impacts the user may cause as a result of a spill or slug load. An accidental discharge/slug control plan shall address, at a minimum, the following:
A. Description of discharge practices, including non-routine batch discharges;
B. Description of stored chemicals, including quantity of chemicals and type and number of storage containers;
C. Site diagram showing location of all tanks holding greater than or equal to two hundred fifty (250) gallons or areas containing eight (8) drums or more of raw materials, prohibited wastes, hazardous wastes or final product. Identification and location of all liquid materials, as well as locations of drains to the sanitary sewer in the vicinity of the storage area(s), is mandatory;
D. Procedures for immediately notifying the pretreatment coordinator of any accidental or slug discharge, as required by section 8-2-9-7 of this chapter;
E. Location of notice/signs posted in conspicuous places advising employees in English and the language of common use whom to call in the event of a spill, accidental discharge of prohibited materials, slug discharge or a bypass of any part of a pretreatment system;
F. 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. Building containment structures or production equipment changes are considered procedures to prevent adverse spills. If containment structures are connected to the sanitary sewer, a valve normally left in a closed position is required;
G. Documentation to ensure that all employees who are in a position to cause, discover, or observe such discharge are advised of the emergency notification procedures;
H. Documentation such as logs to verify inspection and maintenance procedures to prevent adverse impacts and confirm that said procedures are being performed on a regular basis must be maintained incorporated. Logs are required to verify valves, if present, are closed in containment structures; and
I. Emergency telephone number (twenty four (24) hour) off-site and backup telephone number. If the spill plan has been submitted, any change in the telephone numbers should be submitted within five working days when revised. (Ord. 20-08-25, 8-10-2020)
