(A) Limitations on wastewater strength.
(1) National Categorical Pretreatment Standards. National categorical pretreatment standards as promulgated by the U.S. EPA pursuant to the Act (33 U.S.C. §§ 1251 et seq.) shall be met by all industrial dischargers of the regulated industrial categories. An application for modification of the national categorical pretreatment standards may be considered for submittal to the Regional Administrator by the village, when the village's wastewater treatment system achieves consistent removal of the pollutants as defined by 40 C.F.R. § 403.7.
(2) State requirements. State requirements and limitations on discharges to the treatment works shall be met by all industrial dischargers which are subject to the standards in any instance in which they are more stringent than federal requirements and limitations on those in this subchapter or any other applicable ordinance.
(3) Right of revision. The village reserves the right to amend this subchapter to provide for more stringent limitations or requirements on discharges to the treatment works where deemed necessary to comply with the objectives set forth in § 52.22.
(4) Dilution. No industrial discharger shall increase the use of potable or process water in any way, nor mix separate waste streams for the purpose of diluting a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the standards set forth in this subchapter.
(B) Accidental discharges.
(1) Each industrial discharger shall provide protection from accidental discharge of prohibited or regulated materials or substances established by this subchapter. Where necessary, facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the industrial discharger's cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the Village Council for review, and shall be approved by the Village Council before construction of the facility. No industrial discharger who discharges to the treatment works shall be permitted to introduce pollutants into the system until accidental discharge protection procedures have been approved by the Village Council. Review and approval of the plans and operating procedures by the Village Council shall not relieve the industrial discharger from the responsibility to modify its facility as necessary to meet the requirements of this subchapter.
(2) Industrial dischargers shall notify the Village Council immediately upon the occurrence of a "slugload" or accidental discharge of substances prohibited by this subchapter. The notification shall include location of discharge, date and time thereof, type of waste, concentration and volume and corrective actions. Any industrial discharger who discharges a slugload of prohibited materials shall be liable for any expense, loss or damage to the treatment works in addition to the amount of any fines imposed on the village on account thereof under state or federal law.
(3) Signs shall be permanently posted in conspicuous places on the industrial discharger's premises, advising employees whom to call in the event of a slug or accidental discharge. Employers shall instruct all employees who may cause or discover a discharge with respect to emergency notification procedure.
