Article IV. Industrial Discharger and Other Prohibited Discharges

13.10.320 Declaration of policy.

It is the policy of the city of Pilot Rock to provide the planning, engineering and administration necessary to develop and manage sewer facilities that are adequate for the transportation, treatment and disposal of wastes from within and without the city and to operate the sewer system in a manner which protects public health and the environment. In carrying out this policy, the objectives of this article are:

(1) To prevent pollutants from entering the sewer system which will interfere with its normal operation or contaminate the resulting sludge;

(2) To protect the health of the city employees working in the city sewer district collection system and at the wastewater treatment plant;

(3) To prevent the introduction of pollutants into the sewerage system which will not be adequately treated and will pass through into the environment; and

(4) To improve the opportunity for recycling and reclamation of wastewater and sludge.

It is the intent of the city to provide needed sewer service to all users while meeting the outlined objectives. This article provides the structure by which the service will be provided for industrial waste so that the system is protected and can continue to provide efficiently for the waste treatment needs of the city. [Ord. 433 § 32, 1994].

13.10.330 Prohibited practices.

It shall be unlawful for any person to place, deposit or permit to be deposited in any unsanitary manner upon public or private property within the city of Pilot Rock, or in any area under the jurisdiction of said city, any human or animal excrement, garbage or other objectionable waste. It shall be unlawful to discharge into any outlet within the city any sanitary sewage, industrial wastes, or other polluted waters, except where suitable treatment has been provided in accordance with subsequent provisions of this chapter. [Ord. 433 § 33, 1994].

13.10.340 General discharge prohibitions.

No discharger shall contribute or cause to be discharged, directly or indirectly, any of the following described substances into the wastewater disposal system or otherwise to the facilities of the authority:

(1) Any liquids, solids or gases which by reason of their nature or quantity are, or may be, sufficient either alone or by interaction with other substances to cause fire or explosion or be injurious in any other way to the POTW or to the operation of the POTW. At no time shall two successive readings on an explosion hazard meter, at the point of discharge into the system (or at any point in the system), be more than five percent nor any single reading over 10 percent of the lower explosive limit (LEL) of the meter. Prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides and sulfides, and any other substance which the authority, the state or USEPA has notified the user is a fire hazard or a hazard to the system.

(2) Any solid or viscous substances which may cause obstruction to the flow in a sewer or other interference with the operation of the wastewater treatment facilities, such as, but not limited to: grease, shredded garbage with particles greater than one-half inch in any dimension, animal guts or tissues, paunch manure, bones, hair, hides, or fleshings, entrails, whole blood, feathers, ashes, cinders, sand, spent lime, stone or marble dusts, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, waste paper, wood, plastics, gas, tar, asphalt residues, residues from refining or processing of fuel or lubricating oil, mud, or glass grinding or polishing wastes, fruit peelings and cores from canneries and packing plants, cull fruits and vegetables, fruit and vegetable pits.

(3) Any wastewater having a pH less than 6.0 or greater than 9.0 unless the treatment works is specifically designed to accommodate such wastewater, or wastewater having any corrosive property capable of causing damage or hazard to structures, equipment and/or personnel of the city.

(4) Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, or to exceed the limitation set forth in categorical pretreatment standards.

(5) Any noxious or malodorous liquids, gases or solids which either singly or by interaction are capable of creating a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for their maintenance and repair.

(6) Any substance which may cause the POTW’s effluent or treatment residues, sludges or scums to be unsuitable for reclamation and reuse or to interfere with the reclamation process. In no case shall a substance discharged to the POTW cause the POTW to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Act: any criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substance Control Act or state standards applicable to the sludge management method being used.

(7) Any substance which may cause the POTW to violate its NPDES and/or other disposal system permits.

(8) Any substance with objectionable color not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions.

(9) Any wastewater having a temperature which may inhibit biological activity in the POTW treatment plant resulting in interference; but in no case, wastewater with a temperature at the introduction into the POTW which exceeds 40 degrees Celsius (104 degrees Fahrenheit) unless the POTW treatment plant is designed to accommodate such temperature. If, in the opinion of the authority, lower temperatures of such wastes could harm either the sewers, sewage treatment processes or equipment; have an adverse effect on the receiving streams or otherwise endanger life, health, or property; or constitute a nuisance, the authority may prohibit such discharges.

(10) Any slug load, which shall mean any pollutant, including oxygen-demanding pollutants (BOD, etc.), released in a single extraordinary discharge episode of such volume or strength as to cause interference to the POTW. In no case shall a slug load contain concentrations or quantities of pollutants that exceed for any time period longer than 15 minutes more than five times the average 24-hour concentration, quantities or flow during normal operation.

(11) Any unpolluted water including, but not limited to, noncontact cooling water, surface run-off, ground water, roof runoff, or unpolluted industrial process water.

(12) Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration as exceed limits established by the administrative authority in compliance with applicable state or federal regulations.

(13) Any wastewater which, in the opinion of the administrative authority, can cause harm either to the sewers, sewage treatment process or equipment; have an adverse effect on the receiving stream; or can otherwise endanger life, limb, public property, or constitute a nuisance, unless permitted under special agreement by the administrative authority (except that no special waiver shall be given from categorical pretreatment standards).

(14) Wastewater containing substances not amenable to treatment or reduction by the sewage treatment processes employed, or are amenable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters or wastewater which contains substances that cannot be treated economically.

(15) Any solids or hazardous waste from septic tanks except as provided in Article V of this chapter. [Ord. 433 § 34, 1994].

[Ord. 433 § 35, 1994].

13.10.360 Limitations on wastewater strengths.

(1) National Categorical Pretreatment Standards. National categorical pretreatment standards, as promulgated by the U.S. Environmental Protection Agency (USEPA) pursuant to the Act and as adopted by the city, shall be enforceable by this article and shall be met by all dischargers of the regulated industrial categories. An application for modification of the national categorical pretreatment standards may be considered for submittal to the Regional EPA Administrator by the city, when the city’s wastewater treatment system achieves consistent removal of the pollutants as defined by 40 CFR 403.7.

(2) State Requirements. State requirements and limitations on dischargers to the POTW shall be met by all dischargers which are subject to such standards in any instance in which they are more stringent than federal requirements and limitations or those in this chapter or any other applicable ordinance.

(3) Right of Revision. The city reserves the right to amend this article to provide for more stringent limitations or requirements on discharges to the POTW where deemed necessary to comply with the objectives set forth in PRMC 13.10.320.

(4) Dilution. No discharger shall increase the use of potable or process water in any way for the purpose of diluting a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the applicable standards set forth in this article. The city may impose mass limitations on dischargers which are using dilutions to meet the applicable pretreatment standards or requirements of this article, or in other cases where the imposition of mass limitations is deemed appropriate by the city.

(5) Local Limits. In addition to categorical pretreatment standards referenced in subsection (1) of this section, no discharger shall discharge wastewater containing concentrations (and/or mass limitations) of substances exceeding the local limits established by a resolution of the city council.

Wherever a discharger is subject to both a categorical pretreatment standard and a local limit for a given pollutant, the more stringent shall apply. [Ord. 433 § 36, 1994].

13.10.370 Accidental discharges.

As appropriate, dischargers shall provide protection from accidental discharge of prohibited or regulated materials or substances established by this article. Where deemed necessary by the city, facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the discharger’s cost and expense. An accidental spill prevention plan (ASPP) showing facilities and operating procedures to provide this protection shall be submitted to the city for review and approval before implementation. The city shall determine which discharger is required to develop an ASPP and require said discharger to submit the ASPP within 60 days after notification by the city. Each discharger shall implement its ASPP as submitted after such ASPP has been reviewed and approved by the city. Review and approval of such plans and operating procedures by the city shall not relieve the discharger from the responsibility to modify its facility as necessary to meet the requirements of this article.

Dischargers shall notify the city (wastewater treatment plant) immediately upon the occurrence of a “slug” or accidental discharge of substances prohibited by this article. The notification shall include location of discharge, date and time thereof, type of waste, concentration and volume and corrective actions. Any discharger who discharges slugs of prohibited materials shall be liable for any expense, loss or damage to the POTW, in addition to the amount of any fines imposed on the city on account thereof under state or federal law.

Signs shall be permanently posted in conspicuous places on discharger’s premises, advising employees whom to call in the event of a slug or accidental discharge. Employers shall instruct all employees who may cause or discover such a discharge with respect to emergency notification procedure. [Ord. 433 § 37, 1994].

13.10.380 Pretreatment.

Dischargers shall provide necessary wastewater pretreatment as required to comply with this article and shall achieve compliance with all applicable pretreatment standards within the time limitations as specified by appropriate statutes, regulations, and ordinances. Any facilities required to pretreat wastewater to a level acceptable to the city shall be provided, properly operated and maintained at the discharger’s expense. Detailed plans showing the pretreatment facilities shall be submitted to the city for review and must be acceptable to the city before construction of the facility. The review of such plans shall in no way relieve the discharger from the responsibility of modifying its facility or operations as necessary to produce an effluent acceptable to the city under the provisions of this article. Within a reasonable time after the completion of the wastewater pretreatment facility, the discharger shall furnish its operations and maintenance procedures for the city to review, and a copy of maintenance records to be reviewed annually by the city. Any subsequent significant changes in the pretreatment facilities or method of operation shall be reported to and be accepted by the city prior to the discharger’s initiation of the changes. [Ord. 433 § 38, 1994].

13.10.390 Fees.

It is the purpose of this section to provide for the payment of fees from dischargers to the city’s wastewater disposal system, to compensate the city for the cost of administration of the pretreatment program established herein. [Ord. 433 § 39, 1994].

13.10.400 Charges and fees.

If costs are incurred beyond operation through involvement with noncomplying dischargers, the city shall charge the noncomplying discharger for any monitoring, laboratory analyses, inspections, and/or surveillance required by federal pretreatment requirements. [Ord. 433 § 40, 1994].

13.10.410 Administration.

Wastewater dischargers shall comply with the terms of this article. It shall be unlawful to discharge sewage, industrial wastes or other wastes to any sewer outlet within the jurisdiction of the city and/or to the POTW without having first complied with the terms established by administrative authority pursuant to this chapter or without having first obtained the city’s approval of a compliance schedule submitted by the discharger. [Ord. 433 § 41, 1994].

[Amended during 2011 codification; Ord. 433 § 42, 1994].

13.10.430 Reporting requirements for discharger.

(1) Final Compliance Report. Within 90 days following the date for final compliance by the discharger with applicable pretreatment standards and requirements set forth in this article or a wastewater discharge permit, or within 30 days following commencement of the introduction of wastewater into the POTW by a new source discharger, any discharger subject to this article shall submit to the city a report indicating the nature and concentration of all prohibited or regulated substances contained in its discharge, and the average and maximum daily flow in gallons. The report shall state whether the applicable pretreatment standards or requirements are being met on a consistent basis and, if not, what additional O&M and/or pretreatment is necessary to bring the discharger into compliance with the applicable pretreatment standards or requirements. This statement shall be signed by an authorized representative of the discharger as defined in 40 CFR 403.12(i).

(2) Periodic Compliance Reports.

(a) Any discharger subject to a pretreatment standard set forth in this article, after the compliance date of such pretreatment standard, or in the case of a new source discharger, after commencement of the discharge to the city, shall submit to the city quarterly, unless required more frequently by the city, in the discharger’s wastewater discharge permit a report indicating the nature and concentration of prohibited or regulated substances in the effluent which are limited by the applicable pretreatment standards hereto. In addition, this report shall include a record of all measured or estimated average and maximum daily flows during the reporting period. Flows shall be reported on the basis of actual measurement; provided, however, where cost or feasibility considerations justify, the city may accept reports of average and maximum flows estimated by verifiable techniques. The city, for good cause shown considering such factors as local high or low flow rates, holidays, budget cycles or other extenuating factors, may authorize the submission of said reports on months other than those specified above.

(b) Reports of dischargers shall contain all results of sampling and analysis of the discharge, including the flow and the nature and concentration, or production and mass where required by the city. If a discharger monitors any pollutants more frequently than required by the city, all monitoring results must be included in the periodic compliance reports. The frequency of monitoring by the discharger shall be as prescribed within the wastewater discharge permit. All analyses shall be performed in accordance with 40 CFR 136, or with any other test procedures approved by the Administrator of the USEPA. (Where 40 CFR 136 does not include a sampling or analytical technique for the pollutant in question, or where the Administrator determines that the Part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analyses shall be performed using validated analytical methods or any other sampling and analytical procedures, including procedures suggested by the city of Pilot Rock or other parties and approved by the administrative authority.) [Ord. 433 § 43, 1994].

13.10.440 Monitoring facilities.

Each monitoring facility shall be situated on the discharger’s premises, except where such a location would be impractical or cause undue hardship on the discharger, the city may concur with the facility being constructed in the public street or sidewalk area, providing that the facility is located so that it will not be obstructed by landscaping or parked vehicles.

There shall be ample room in or near such sampling facility to allow accurate sampling and preparation of samples for analysis. The facility, sampling and measuring equipment shall be maintained at all times in a safe and proper operating condition at the expense of the discharger.

All monitoring facilities shall be constructed and maintained in accordance with all applicable local construction standards and specifications. Construction shall be completed within 60 days of receipt of wastewater discharge permit by discharger. [Ord. 433 § 44, 1994].

13.10.450 Confidential information.

Information and data furnished to the city with respect to the nature and frequency of discharge shall be available to the public or other governmental agency without restriction unless the discharger specifically requests, and is able to demonstrate to the satisfaction of the city, that the release of such information would divulge information, processes or methods of production entitled to protection as trade secrets or proprietary information of the discharger.

When requested by a discharger furnishing a report, the portions of a report which may disclose trade secrets or secret processes shall not be made available for inspection by the public, but shall be made available upon written request to governmental agencies for uses related to this article, the national pollutant discharge elimination system (NPDES) permit, state disposal system permit, and/or the pretreatment programs; provided, however, that such portions of a report shall be available for use by the state or any state agency in judicial review or enforcement proceedings involving the discharger furnishing the report. Wastewater constituents and characteristics will not be recognized as confidential information.

Information accepted by the city as confidential shall not be transmitted to any governmental agency or to the general public by the city until and unless a 30-day notification is given to the discharger. [Ord. 433 § 45, 1994].

13.10.460 Emergency suspension of service and wastewater discharge permit.

The city may, after informal notice to the discharger (in writing, in person, or by telephone), order the suspension of the wastewater treatment service and revoke the wastewater discharge permit to a discharger when it appears to the city that an actual or threatened discharge:

(1) Presents or threatens an imminent or substantial danger to the health or welfare of persons or substantial danger to the environment; or

(2) Threatens to interfere with the operation of the POTW, or to violate any pretreatment limits imposed by this article.

Any discharger notified of the city’s suspension order shall immediately cease all discharges. In the event of failure of the discharger to comply with the suspension order, the city may immediately take all necessary steps to halt or prevent any further discharge by such discharger into the POTW. The city shall have authority to physically cap, block or seal the discharger’s sewer line (whether on public or private property) in order to terminate service under this section.

The city shall have the right to enter upon the discharger’s property to accomplish the capping, blocking or sealing of the discharger’s sewer line. The city may also commence judicial proceedings immediately thereafter to compel the discharger’s specific compliance with such order and/or to recover civil penalties. The city shall reinstate the wastewater discharge permit and/or wastewater treatment service upon clear and convincing proof by the discharger of the elimination of the noncomplying discharge or conditions creating the threat as set forth in this section. All emergency suspensions of service shall be confirmed in writing to discharger as soon as possible and discharger shall be liable for all costs which the city may incur as a result of an emergency suspension.
