§ 1042.20 PRETREATMENT REQUIREMENTS.
   (a)   The city may reject wastes for any reason the Director of Public Works and Services deems appropriate. Wastewater shall meet the minimum requirements established in this chapter before being discharged into any public sewer. The Director may issue orders to require compliance with any requirement or this chapter, including applicable categorical pretreatment standards, other discharge limits and reporting requirements. Any violation of such orders shall be considered a violation of this chapter and shall subject the user to the penalty provisions contained herein. If the Director determines that an existing or proposed discharge could cause damage to, impose an unreasonable burden upon or be inadequately treated by the sewage works, he or she shall require the user, at his or expense, to:
      (1)   Reduce or modify the objectionable characteristics of the wastes to meet limits or conditions specified in this chapter prior to discharging these wastes to a public sewer;
      (2)   Control the quantities and rates of discharge of the wastes over a 24-hour day and seven-day week; or
      (3)   Dispose of the wastes and prevent them from entering the sewage works.
   (b)   Plans, specifications, operating procedures, compliance schedules and other pertinent information relating to proposed pretreatment or control facilities shall be submitted to the Director for approval. Construction of such facilities shall not begin until written approval is obtained from the Director. The review of such plans and procedures shall in no way relieve the person from the responsibility of modifying the facilities as required to produce an effluent meeting the requirements of this chapter. Any subsequent change in the pretreatment facilities or operating procedures shall be submitted to and approved by the Director before the change is implemented.
   (c)   All pretreatment facilities shall be maintained continuously in satisfactory and effective operation by the person, at his or her expense, subject to periodic inspection by the Director. Such person shall maintain operating records and shall submit, at the request of the Director, a summary report of the character of the influent and effluent, showing the performance of the pretreatment facilities.
   (d)   National categorical pretreatment standards promulgated by the USEPA pursuant to the Federal Act shall be met by all dischargers of the regulated industrial categories. Where these national categorical pretreatment standards are more stringent than those specified in this chapter, this chapter shall be amended to adopt the more stringent standards within nine months of the promulgation of a national categorical pretreatment standard, to require compliance by dischargers subject to such standard within the time frame specified by the same. All national categorical pretreatment standards adopted after the effective date of this chapter (Ordinance 86-32, passed June 23, 1986) shall be adopted by the city as part of this chapter. All persons regulated by the more stringent categorical pretreatment standards shall be notified of any proposed change prior to such effective date, and shall comply with the applicable standards by such effective date. Any change or new provision in this chapter shall include a reasonable time schedule for compliance.
   (e)   Where a person subject to a national categorical pretreatment standard has not submitted a discharge report as required in § 1042.22, he or she shall file a completed report within six months after the promulgation of the applicable national categorical pretreatment standard. Where a person has submitted an acceptable discharge report, he or she shall submit to the Director any additional information required by the national categorical pretreatment standard within six months after such promulgation.
   (f)   Where the wastewater treatment plant achieves substantial and consistent pollutant removal, revisions of the national categorical pretreatment standards shall be considered by the Director upon the written request of a regulated person, according to the criteria and provisions of § 403.7 of the General Pretreatment Regulations. In any case, the Director shall require that the person’s discharge shall not cause the wastewater treatment plant effluent to violate applicable water quality standards and effluent limitations specified in the city’s NPDES permit.
