A. Permit Required: Before any person shall discharge industrial wastes into the Municipal sewers of the City, it shall be the duty of the person to first obtain from the Public Works Director a permit therefor.
B. Application For Permit: Application for permit to discharge such waste in the Municipal sewers shall be made in writing and shall contain the following minimum information:
1. Name and address of applicant.
2. Location of connection or proposed connection with Municipal sewers.
3. Industrial processes which produce said wastes.
4. Statement as to the approximate times of discharge.
5. Estimated quantity of wastes to be discharged including as a minimum; flow, BOD5, suspended solids, and any constituent which is included in Federal Categorical Pretreatment Standards applicable to processes involved. Information shall be included as to the peak and average loads to be discharged.
If the Public Works Director then determines that additional information is needed for enforcement of this Chapter, said information shall be provided by the applicant prior to issuance of a permit.
C. Issuance Of Permit: The Public Works Director shall issue to the applicant a permit, as required, in the event that he/she finds and determines:
1. That there is unused carrying and treatment capacity not necessary for the disposition of domestic sewage of the City.
2. That the amount and character of the wastes proposed to be discharged by the applicant is such that the same can be transported and treated in such a manner that an effluent will result which complies with all applicable State and Federal laws and regulations, and which will not result in a nuisance nor any objectionable odors along the pipelines or in the vicinity of wastewater treatment plant and other wastewater facilities.
3. That such wastes will not result in damage to pipelines and other wastewater facilities.
D. Permit Charges: All industry discharging or proposing to discharge to City sewers shall be subject to permit regulations on the effective date of this Chapter. Existing permits will remain in effect but may be revised and reissued by the Public Works Director according to the limitations of this Chapter. Before granting any permit under the provisions of this Section, the City shall require the payment of fees as adopted by resolution of the Council.
E. Revocation Of Permit: In the event that after granting a permit, as provided for in this Chapter, it shall develop, by reason of increased waste concentrations, or changes in composition of the effluent, or changes in composition of the wastewater discharge, that the discharge causes a nuisance or objectionable odors or objectionable conditions along the lines or in the vicinity of the wastewater treatment plant or other facilities, or results in damage to pipelines or other facilities or violates a State or Federal law, then at his/her discretion, the Public Works Director may revoke the permit, or may impose further conditions with respect thereto, toward the end of remedying such conditions.
F. Inspection Facility: A customer responsible for any discharge of industrial wastes shall provide, at his/her own expense, suitable means of inspection to facilitate observation, sampling, and measurement of wastes. Such facility may be a manhole but in all cases shall include a flume and flow meter acceptable to the Public Works Director and shall provide space for an automatic sampler. Such inspection facility shall be maintained in a manner that is safe and accessible to City personnel at all times. Installation, operation and maintenance of the sampling facilities shall be the responsibility of the customer discharging industrial wastewater and shall be subject to the approval of the Public Works Director.
G. Waste Sampling:
1. Industrial wastes discharged into the public sewers shall be subject to periodic inspection, sampling, and a determination of character and concentration of said wastes for billing and ordinance compliance requirements. The determination shall be made by the Public Works Director or his/her representatives as often as may be deemed necessary by the Public Works Director.
2. Samples shall be collected in such a manner as to be representative of the composition of the wastes. The sampling may be accomplished either manually or by the use of mechanical equipment acceptable to the Public Works Director, and at his/her discretion.
3. Access to sampling locations for the purpose of periodic sampling shall be granted to the Public Works Director or his/her duly authorized representatives at all times. Every care shall be exercised in the collection of samples to ensure their preservation in a state comparable to that at the time the sample was taken.
H. Analysis:
1. Analyses of industrial wastewater as required for the enforcement of this Chapter and the determination of use charges will be conducted at the discretion of the Public Works Director by either the wastewater treatment plant laboratory or another laboratory selected by the Public Works Director. The laboratory performing the analysis shall be certified by the State for the analysis required.
2. Cost of sampling and analysis performed by the wastewater treatment plant laboratory will be billed to the customer when, in the opinion of the Public Works Director because of the quantity or quality of the wastes discharged, a greater number of analyses than normal are required to ensure compliance with this Chapter. Costs for sampling and analysis performed by another laboratory, shall be billed to the customer at cost to the City.
3. At the option of the Sewer Service Charge Review Board, all sampling and analysis performed by the wastewater treatment plant laboratory may be charged to the customer.
4. A schedule of charges for analyses conducted by the wastewater treatment plant laboratory, shall be adopted by the Sewer Service Charge Review Board and approved by the City Council.
5. Self-monitoring (sampling and analyses of waste discharges) by the industrial discharger which is performed by or for the discharger shall be summarized and submitted to the Public Works Director not less than once annually, or more often if required by the Public Works Director. All records of these analyses shall be retained for not less than two (2) years and made available by the customer for inspection by the Public Works Director or his/her duly authorized representatives.
6. Laboratory procedures used in the examination of industrial wastes shall be those set forth in the current edition of Standard Methods for the Examination of Water and Wastewater. However, alternative methods for certain analyses of industrial wastes may be used subject to mutual agreement between the Public Works Director and the customer.
I. Basis For Charges: Determination of the character and concentration of the industrial wastewater and the mass of BOD5 and suspended solids discharged shall be made by the City and these determinations shall be binding as a basis for charges.
J. Admission Of Wastes Into Storm Waters: Industrial cooling water, blow-down from cooling towers or evaporative coolers, wash water waste or waters which are odorless, stable and free from deleterious chemicals shall, where practicable, be discharged into storm drains or storm water channels. For the purpose of this Section, any industrial wastewater, waters, or liquids, containing less than twenty five (25) ppm BOD or which meet the most recent requirement for secondary treatment as defined by State Water Resources Control Board, shall be deemed stable. The admission of such waters into the public storm sewers shall be limited to unpolluted wastewater providing that it does not violate any provision of this Code and providing that it meets Federal or State laws and regulations which may be applicable to said discharge.
