(a) 
Users shall provide wastewater treatment as necessary to comply with this division and shall achieve compliance with all categorical pretreatment standards, local limits, authority local limits and/or pretreatment requirements including other measures implemented by Gulf Coast Waste Disposal Authority, and prohibitions set forth in this division within the timeframe specified by EPA, the state, or the director, whichever is more stringent.
(b) 
Pretreatment facilities necessary for compliance must be provided, operated, inspected, and maintained at the user’s expense.
(c) 
Detailed plans describing pretreatment facilities and their operating procedures shall be submitted to the director for review and shall be acceptable by the director prior to construction of the facilities. The review of such plans and/or operating procedures shall in no way relieve the user from the responsibility of modifying such facilities as necessary to produce a discharge acceptable to the control authority under the conditions of this division.
(d) 
Subsequent significant changes in the pretreatment facilities or methods of operation must be reported to and be acceptable to the control authority prior to the initiation of the changes.
(e) 
The director may require users, at the user’s expense, to restrict their discharge during peak flow periods, discharge certain wastewater only into specifically designated sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from process wastestreams, and initiate such other conditions as may be necessary to protect the POTW(s) and determine the user’s compliance with the requirements and objectives of this division.
(f) 
The director may require any user discharging to the POTW(s) to install and maintain, on their property and at their expense, a suitable storage and flow control facility to ensure equalization of flow or compliance prior to discharge.
(g) 
Grease, oil, and sand interceptors shall be provided by the user when, in the opinion of the director, they are necessary for the proper handling of wastewater containing excessive amounts of grease, oil, or sand, except that such interceptors shall not be required for property solely used for residential purposes. All interceptors shall be of type and capacity approved by the city’s building and inspection department and shall be so located so as to be easily accessible for cleaning and inspection.
(h) 
Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the user at the user’s expense.
(i) 
Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible meter.
(Ordinance 2011-01, sec. 1, adopted 1/11/11)
(a) 
At least once every two (2) years, the director shall evaluate whether each significant industrial user needs an accidental discharge/slug control plan.
(b) 
Within one (1) year of being designated as a significant industrial user, the director will determine whether the new significant industrial user needs a plan or other action to control slug discharges.
(c) 
When conditions may exist that reasonably could result in an accidental or slug discharge, the director may require any user to develop, submit for approval, and implement an accidental discharge/slug plan or take other such actions that may be required to control slug discharges. These requirements may be incorporated into the user’s permit. Review and approval of the plan shall not relieve the user from any responsibility associated with an accidental/slug discharge.
(d) 
The accidental discharge/slug control plan shall address, at a minimum, the following:
(1) 
Description of discharge practices, including non-routine batch discharges;
(2) 
Description of stored chemicals;
(3) 
Procedures for immediately notifying the director of any accidental or slug discharges, as required by section 13-2-265 of this division.
(4) 
Procedures to prevent adverse impact from any accidental or slug discharge, including, but 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, monitoring, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents, and plans and equipment for emergency response.
(e) 
Each user, deemed necessary by the director, shall provide and maintain at the user’s expense such facilities determined to be necessary to provide protection from accidental or slug discharges. Design specifications for these facilities must be submitted to the director for review and approval. Review and approval of such specifications shall not relieve the user from the responsibility of modifying the facility to meet the requirements of this division.
(f) 
When deemed necessary by the director because of a reasonable risk of an accidental or slug discharge, a notice shall be permanently posted in conspicuous places on the user’s premises advising employees who to call in the event of a slug or accidental discharge. Employers shall instruct all employees who may cause or discover a discharge concerning emergency notification procedures.
