(a) Wastewaters with Special Characteristics.
(1) Pursuant to 40 CFR 403.8 the Manager should initially rely upon the Federal Categorical Pretreatment Standards of Section 932.06
(c) to protect wastewater facilities or receiving waters, if any wastewater which contains substances or possesses characteristics shown to have deleterious effect upon the wastewater facilities, processes, equipment or receiving waters, or constitutes a public nuisance or hazard, is discharged or is proposed for discharge to the wastewater sewers, the Manager may:
A. Require pretreatment to a condition acceptable for discharge to the wastewater sewers.
B. Require control over the quantities and rates of discharge.
C. Require payment to cover added cost of handling and treating the wastewaters not covered by existing fees or charges.
D. Require the development of compliance schedules to meet any applicable pretreatment requirements.
E. Require the submission of reports necessary to assure compliance with applicable pretreatment requirements.
F. Carry out all inspection, surveillance and monitoring necessary to determine compliance with applicable pretreatment requirements.
G. Obtain remedies for noncompliance by any user. Such remedies may include injunctive relief, the civil penalties specified in Section 932.02
or appropriate criminal penalties, or
H. Reject the wastewater if scientific evidence discloses that discharge will create unreasonable hazards or have unreasonable deleterious effects on the wastewater facilities.
(2) When considering the above alternatives, the Manager shall assure that conditions of the City’s NPDES permit are met. The Manager shall also take into consideration cost effectiveness and the economic impact of the alternatives on the discharge. If the Manager allows the pretreatment or equalization of wastewater flows, the installation of the necessary facilities shall be subject to review. The Manager shall review and recommend any appropriate changes to the program, within thirty days of submittal.
(3) Where pretreatment or flow-equalizing facilities are provided or required for any wastewater, they shall be maintained continuously in satisfactory and effective operation at the expense of the owner.
(Ord. 1463-90. Passed 5-29-90.)
(b) Compliance with Pretreatment Requirements. Pursuant to 40 CFR 403.12 persons required to pretreat wastewater in accordance with subsection (a) hereof shall provide a statement, reviewed by an authorized representative of the user and certified to by a qualified person indicating whether applicable pretreatment requirements are being met on a consistent basis and, if not, describe the additional operation and maintenance or additional pretreatment required for the user to meet the pretreatment requirements. If additional pretreatment or operation and maintenance will be required to meet the pretreatment requirements the user shall submit a plan (including schedules) to the Manager. The plan (including schedules) shall be consistent with applicable Federal laws as indicated by 40 CFR 403.12(b)(7).
(c) Monitoring Requirements. Discharges of wastewater to the City’s wastewater facilities from the facilities of any user shall be monitored in accordance with the provisions of Section 932.07
(b) and (c).
(d) Effect of Federal Law. In the event that the Federal government promulgates a regulation for a given new or existing user in a specific industrial subcategory that establishes pretreatment standards or establishes that such a user is exempt from pretreatment standards, such Federal regulations shall immediately supersede subsection (a)(1) hereof as indicated by 40 CFR 403.7 and 403.9.
(e) Revision of Pretreatment Standards. The Manager shall promptly apply for and obtain authorization from the EPA to revise discharge limitations for those substances listed in the Federal Categorical Pretreatment Standards for which consistent removal occurs in the wastewater treatment facilities of the City. The Manager shall not adopt or enforce discharge limitations more stringent than the requested limitations until the State or EPA acts on the application. (Ord. 1463- 90. Passed 5-29-90.)
