National Categorical Pretreatment Standards as promulgated by the U.S. EPA pursuant to the Clean Water Act shall be met by all affected dischargers. The City shall notify all affected dischargers of the applicable reporting requirements under 40 CFR 403.12. The City hereby adopts the National Categorical Pretreatment Standards by reference.
A. 
Whenever deemed necessary, the Director or designee may require nonresidential dischargers to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage waste streams from industrial waste streams, and such other conditions as may be necessary to protect the WRRF and determine the discharger's compliance with requirements of this chapter.
B. 
The Director may require any nonresidential discharger to install and maintain, on their property and at their expense, a suitable storage and flow control facility to ensure equalization of flow. A WDP may be issued solely for flow equalization.
C. 
Where preliminary treatment or flow-equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at their expense.
D. 
Nonresidential dischargers with potential to discharge flammable substances shall be required to install and maintain an approved combustible gas detection meter.
The Director shall evaluate whether a nonresidential discharger needs an accidental discharge/slug discharge control plan or other action to control slug discharges. The Director may require any nonresidential discharger to develop, submit for approval, and implement such a plan or take such other action that may be necessary to control slug discharges. An accidental discharge/slug discharge control plan shall address, at a minimum, the following:
A. 
Description of discharge practices, including non-routine batch discharges; description of stored chemicals;
B. 
Procedures for immediately notifying the Director or designee of any accidental or slug discharge, as required in § 176-9.03; and
C. 
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 transferring 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.
