This chapter sets requirements for the discharge of pollutants into the city sewerage system. The objectives of this chapter are to:
(1) Prevent the discharge of pollutants into the city sewerage system which will interfere with the operation of the system or contaminate the resulting sludge;
(2) Prevent the discharge of pollutants into the city sewerage system which will pass through the system, inadequately treated, into receiving streams;
(3) Improve the opportunity to recycle and reclaim wastewater and sludge from the city sewerage system.
In achieving the objectives of this chapter, it shall be the policy of the city to actively support the community’s commerce and industry through accommodation, assistance and cooperation consistent with the city’s responsibility to protect the waters of the state from pollution and to secure the health, safety and welfare of the residents of the metropolitan area.
Pollutants shall be accepted into the city sewerage system subject to regulations and requirements as may be promulgated by state and federal regulatory agencies or the city for the protection of sewerage facilities and treatment processes, public health and safety, receiving water quality and avoidance of nuisance. As a minimum, nonresidential users of the city sewerage system shall comply with the applicable pretreatment standards developed under state (OAR 340-45-063) and federal (40 CFR Part 403) regulations. Pretreatment standards shall be developed to ensure that at a minimum the city and nonresidential users comply with Section 307(b) and 307(c) of the Federal Water Pollution Control Act as amended by the Clean Water Act of 1977 and the regulations promulgated pursuant to these sections of the Act.
Wastewater discharge permit conditions shall be predicated on federal, state and local regulations and requirements and on the results of analysis of the type, concentration, quantity and frequency of discharge including the geographical relationship of the point of discharge to sewerage and treatment facilities.
These permit conditions shall be reevaluated upon expiration of the permit and may be revised from time to time as required to remain consistent with local, state or federal laws, regulations and requirements or to meet any emergency. Wastewater discharge permits may include, but shall not be limited to, conditions pertaining to discharge standards, self-monitoring requirements, treatment methods, housekeeping practices inventory storage, manufacturing methods, etc., that are intended to protect the waters of the state.
Except as otherwise provided herein, the city administrator shall administer, implement, and enforce the provisions of this chapter. (Ord. 2570, 1989)

Any succeeding nonresidential user shall agree to comply with the terms and conditions of the existing permit as a condition precedent to the approval by the city administrator of a transfer sale or assignment of the permit.
(2) Permit holders will be required to submit information, certifications, compliance schedules and samples of discharge or perform such tests and report such test results to the city administrator as follows:
(a) When required by the terms and provisions of 40 CFR 403.12, as amended through the effective date of the ordinance codified in this chapter;
(b) When requested by state or local public agencies; or
(c) When deemed necessary by the city administrator for the proper treatment, analysis or control of discharge. All such tests and reports shall be at the cost of the permit holder.
The city shall have the right to implement and enforce the requirements of 40 CFR 403.12 by order of the city administrator. When deemed necessary by the city administrator, a permit holder may be required to obtain, install, operate and maintain an automatic sampler, analyzer or flow measuring device to monitor its discharges in the manner directed by the city.
All sampling and analysis shall be done in a manner and by a laboratory previously approved by the city administrator. The city administrator shall require all analysis related to National Categorical Pretreatment Standards to be performed in accordance with the procedures established by the EPA pursuant to Section 304(g) of the Act and contained in 40 CFR Part 136 or other applicable analytical procedures approved by the EPA.
To the degree practicable, the city administrator will provide each permit holder or applicant with information on applicable local, state and federal wastewater analysis and reporting requirements; provided however, that any failure to do so shall not excuse the permit holder from compliance with said requirements.
(3) When required by the city administrator, the permit holder shall install and maintain at its expense a suitable control manhole to facilitate observation, sampling, and measurement of wastewater being discharged into the city sewerage system. Such manhole shall be located, if feasible, where it is accessible from a public road or street. It shall be constructed in accordance with plans and at a location approved by the city administrator and shall be arranged so that flow measuring and sampling equipment and a shutoff gate or screen may be conveniently installed by the city.
(4) The city shall have the right to inspect the facilities of any nonresidential user subject to subsection (1)(a) of this section as necessary to determine compliance with pretreatment standards. These inspections shall take place whether or not the provisions of this chapter are being complied with. The owner, operator or agent in charge of premises where wastewater is created or discharged shall allow authorized representative of the city, state and EPA, upon presentation of their credentials, access at all reasonable times to all parts of the premises for the purpose of the performance of any of their duties, including, but not limited to, inspection, observation, sampling, and/or records copying and examination. The city, state and EPA shall have the right to set up on the nonresidential user’s property such devices as may be necessary or proper to conduct sampling, observation, inspection, compliance monitoring and/or metering operations. The nonresidential user shall make arrangements with its employees so that upon presentation of their credentials, representatives from the city, state or EPA will be permitted to enter, without delay, for the purpose of performing their responsibilities.
(5) As a condition of the granting of a wastewater discharge permit, the permit holder may be required to install pretreatment facilities or make plant or process modifications as deemed necessary by the city administrator to meet the requirements of this chapter.
Whenever such facilities or modifications are required, they shall be constructed, installed, operated and maintained at the expense of the permit holder and in a manner and within the time prescribed by the city administrator. The permit holder shall maintain records indicating routine maintenance check dates, cleaning and waste removal dates and means of disposal of accumulated wastes. Such records shall be retained for a minimum of three years and shall be subject to review in accordance with subsection (4) of this section. Approval of proposed facilities or modifications by the city administrator will not in any way guarantee that these facilities or modifications will function in the required manner or attain the required results, nor shall it relieve a permit holder of the responsibility of enlarging or otherwise modifying or replacing such facilities to accomplish the intended purpose and to meet the applicable standards, limitations and conditions of a wastewater discharge permit.
(6) Information and data obtained by the city from reports, questionnaires, permit applications, permits and monitoring programs shall be available to the public and other governmental agencies without restriction unless the permit holder requests in writing that it be confidential and demonstrates to the satisfaction of the city administrator that such records are exempt from disclosure under ORS 192.500(1)(b), (e), or (2)(g). Notwithstanding anything therein to the contrary, all such data shall be available at least to the extent necessary so that the city administrator can ensure compliance with the requirements of 40 CFR 2.302 and to state and federal agencies as required during judicial or enforcement proceedings involving the nonresidential user.
When confidentiality is requested and the right thereto is established by the permit holder, the confidential information shall not be made available for inspection by the public but may be made available upon written request to governmental agencies for uses related to this chapter, the NPDES permit, or pretreatment programs. However, all portions of a report shall be available for use by city, state or any state agency in judicial or enforcement proceeding involving the person furnishing the report. (Ord. 2570 § 8, 1989)
13.12.090 Enforcement.
(1) Any discharge in violation of this chapter, the conditions of the wastewater discharge permit, or any other violation of this chapter is hereby declared to be a public nuisance. Such nuisance may be abated or enjoined and damages assessed therefor in accordance with other provisions in the city code or in any other manner provided by law.
(2) In the event of any actual or threatened discharge into the city sewerage system in violation of this chapter or the conditions of a wastewater discharge permit, such discharge presents an imminent or existing danger to the health and welfare of persons, property or the environment or which has caused or will cause damage to or interference with the operation of the city sewerage system, the city administrator may issue an order to cease and desist and direct that those nonresidential users responsible for such violation:
(a) Comply forthwith;
(b) Comply in accordance with the time schedule set forth by the city administrator; or
(c) Take appropriate remedial or preventive action.
(3) If the nonresidential user in noncompliance fails to comply with the order, the city shall take such steps as are deemed necessary or proper including immediate severance of the sewer connection. The city shall reinstate the wastewater treatment service upon proof of the elimination of the actual or threatened violation. The filing of an appeal pursuant to SHMC 13.12.100 shall not stay enforcement of the city administrator.
(4) If the city administrator finds that a discharge has taken or may take place in violation of this chapter or the conditions of a wastewater discharge permit, the city administrator may require the nonresidential user to submit for approval, within such time and with such modifications as the city administrator deems necessary, a detailed time schedule or specific actions which the nonresidential user shall take in order to prevent or correct the violation.
(5)(a) Any nonresidential user who violates any of the provisions of SHMC 13.12.060 or 13.12.080 or the conditions of its wastewater discharge permit which health, property or the environment or which violation will not cause damage to or interference with the operation of the city sewerage system, may have its wastewater discharge permit revoked and sewer connection severed by order of the city administrator.
(b) The order shall be signed by the city administrator and shall specify the nature and source of the violations. The order shall be delivered or sent by regular mail to the address of the nonresidential user as shown on the permit. The order may specify the corrective actions to be taken and shall allow reasonable time for satisfactory correction. If the permit holder does not correct the violation within the time specified, or such additional time as may be allowed by the city administrator, then the wastewater discharge permit shall be revoked and the sewer connection severed as provided in the order. Correction of the violation shall not include assessment of monetary penalties.
(c) The filing of an appeal pursuant to SHMC 13.12.100 shall stay enforcement of the action by the city administrator under this subsection pending final administrative action on the appeal. This provision supplements and does not restrict other provisions of this code, laws, or regulations authorizing termination of service for delinquency in payments of fees or charges.
(6) The city will publish in a daily newspaper with the largest daily circulation in the metropolitan area in addition to the local newspaper of record, not less than annually, a list of those nonresidential users, which during the previous 12 months were determined to be responsible for wastewater discharge permit violations. This notification will summarize enforcement action by the city during the same 12 months. For purposes of this provision, a significant violation is one which remains uncorrected 45 days after notification of noncompliance; which is part of a pattern of noncompliance over a 12-month period; which involves a failure to accurately report noncompliance; or which resulted in the issuance of a cease and desist order.
(7) The city administrator is authorized and directed to promulgate such rules and regulations as may be deemed necessary or proper to carry out the purposes or provisions of this chapter. Nothing in this chapter shall prevent the city administrator from seeking judicial or governmental agency assistance to implement the purposes and provisions of this chapter. (Ord. 2570 § 9, 1989)
