Industrial users shall provide necessary wastewater treatment as required to comply with this chapter and shall achieve compliance with all categorical pretreatment standards, local limits and the prohibitions set out in Article II of this chapter, within the time limitations specified by the director. Any facilities required to pretreat wastewater to a level acceptable to the city shall be provided, operated, and maintained at the industrial user's expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the city for review, and shall be acceptable to the city before construction of the facility. The review 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 acceptable discharge to the city under the provisions of this chapter.
(Code 1985 § 22-72A)
Whenever deemed necessary, the director may require industrial users to restrict the industrial user's 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 municipal wastewater system and determine the industrial user's compliance with the requirements of this chapter.
(1) 
Each person discharging, into the municipal wastewater system, greater than 100,000 gallons per day or greater than five percent of the average daily flow in the system, whichever is lesser, shall install and maintain, on his property and at his expense, a suitable storage and flow control facility to ensure equalization of flow over a 24-hour period. The facility shall have a capacity for at least 50 percent of the daily discharge volume and shall be equipped with alarms and a rate of discharge controller, the regulation of which shall be directed by the director. A wastewater permit may be issued solely for flow equalization. The director may require such facility for lesser discharges in any case.
(2) 
Grease, oil and sand interceptors shall be provided, when in the opinion of the director, they are necessary for the proper handling of wastewater containing excessive amounts of grease, flammable substances, sand, or other harmful substances; except that such interceptors shall not be required for residential users. All interception units shall be of type and capacity approved by the director and shall be so located as to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the owner, at his expense.
(3) 
Industrial users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
(Code 1985 § 22-72B)
The director may require any industrial user to develop and implement an accidental discharge/slug control plan. At least once every two years, the director shall evaluate whether each significant industrial user needs such a plan. Any industrial user required to develop and implement an accidental discharge/slug control plan shall submit a plan which addresses, at a minimum, the following:
(1) 
Description of discharge practices, including nonroutine batch discharges.
(2) 
Description of stored chemicals.
(3) 
Procedures for immediately notifying the municipal wastewater system of any accidental or slug discharge. Such notification must also be given for any discharge which would violate any of the prohibited discharges in Article II of this chapter.
(4) 
Procedures to prevent adverse impact from any accident. 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 run-off, worker training, building of containment structures, measures for containing toxic organic pollutants (including solvents) and/or measures and equipment for emergency response.
(Code 1985 § 22-72C)
Any person who shall occupy the industrial user's premises as a tenant under any rental or lease agreement shall be jointly and severally responsible for compliance with the provisions of this chapter in the same manner as the owner.
(Code 1985 § 22-72D)
All new and domestic wastewaters from rest rooms, showers, drinking fountains, etc. shall be kept separate from all industrial wastewaters until the industrial wastewaters have passed through a required pretreatment system and the industrial user's monitoring facility. When directed to do so by the director, industrial users must separate existing domestic wastestreams from industrial waste-streams.
(Code 1985 § 22-72E)
No person shall maliciously, willfully or negligently break, damage, destroy, uncover, deface, tamper with or prevent access to any structure, appurtenance or equipment, or other part of the municipal wastewater system. Any person found in violation of this requirement shall be subject to the sanctions set out in Article XI of this chapter.
(Code 1985 § 22-72G)
