§ 51.155 WHEN SURCHARGE IS APPLICABLE.

   Industrial waste surcharge shall be assessed against any person discharging industrial wastes into the city’s sanitary sewer system where the contributed waste strength exceeds that of normal strength wastewater as defined in § 51.002 of this code. Persons subject to the industrial waste surcharge shall be subject to the regular sewer user charges.

(Prior Code, § 51.155)

§ 51.156 POLLUTANTS SUBJECT TO SURCHARGE.

   The monthly amount of pollutants subject to the surcharge will be based on the average loading per facility operating day, in excess of 250 mg/l for BOD5 or suspended solids, in excess of 100 mg/l for biodegradable oils and grease, in excess of 30 mg/l for ammonia, in excess of zero (0) mg/l for hydrogen sulfide, times the number of operating days per month.

(Prior Code, § 51.156)

§ 51.157 AMOUNT OF SURCHARGE.

   (A)   The industrial waste surcharge to be assessed each month will be determined by application of the rates then in effect.

   (B)   The surcharge amount shall be determined by calculating the average number of pollutant pounds per operating day based on the average of periodic grab or composite samples obtained and tested as described in § 51.141.

   (C)   In computing the surcharge amount, no credit will be allowed because pollutant strength is less than that allowed in normal strength wastewater.

(Prior Code, § 51.157)

§ 51.158 REVIEW OF SURCHARGE RATES.

   The Director of Public Works shall review the surcharges annually and adjust them, if necessary, to reflect the actual cost to treat the pollutants subject to the surcharge.

(Prior Code, § 51.158)

§ 51.159 MONITORING FACILITIES.

   When a person discharges a waste that is subject to the industrial waste surcharge, the Director of Public Works may require monitoring facilities. The installation and use of the monitoring facilities shall be in compliance with §§ 51.138 and 51.141 of this code.
