Each industrial user shall notify the Public Works Director or other designee of any planned significant changes to the industrial user's operations or system, which might alter the nature, quality, or volume of its wastewater at least 30 days before the change. Notification of any changes in the listed or characteristic hazardous wastes for which the user has submitted initial notification under 40 C.F.R. 403.12(p) must also be reported.
A. The Public Works Director or other designee may require the industrial user to submit such information as may be deemed necessary to evaluate the changed condition, including the submission of a waste water permit application under § 13.16.060, if necessary.
C. No industrial user shall implement the planned changed condition(s) until and unless the Public Works Director or other designee has responded to the industrial user's notice.
D. For purposes of this requirement, flow or loading increases of 20% or greater and the discharge of any previously unreported pollutant shall be deemed significant.
(Ord. 1413 § 6.5, passed 4-1-2015)
A. In the case of an accidental or other discharge, which may cause potential problems for the municipal wastewater system, it is the responsibility of the user to immediately telephone and notify the City POTW Supervisor or Public Works Director or other designee of the incident. This notification shall include the location of discharge, type of waste, concentration and volume, if known, and corrective actions taken by the user.
B. Within 5 days following an accidental discharge, the user shall, unless waived by the Public Works Director or other designee, submit a detailed written report describing the cause(s) of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage, or other liability which may be incurred as a result of damage to the system, natural resources, or any other damage to person or property; nor shall such notification relieve the user of any fines, civil penalties, or other liability which may be imposed by this chapter.
C. A notice shall be permanently posted on the user's bulletin board or other prominent place advising employees who to call in the event of a discharge described in division A., above. Employers shall ensure that all employees who may cause or suffer such a discharge to occur are advised of the emergency notification procedure.
D. Significant industrial users are required to notify the Public Works Director or other designee immediately of any changes at its facility affecting the potential for a slug discharge. Failure to notify the city of potential problem discharges shall be deemed a separate violation of this chapter.
(Ord. 1413 § 6.6, passed 4-1-2015)
All industrial users not subject to categorical pretreatment standards and not required to obtain a wastewater permit shall provide appropriate reports to the city as the Public Works Director or other designee may require.
(Ord. 1413 § 6.7, passed 4-1-2015)
Samples collected to satisfy reporting requirements must be based on data obtained through appropriate sampling and analysis performed during the period covered by the report, based on data that is representative of conditions occurring during the reporting period.
A. Except as indicated in division B. and C. below, the user must collect wastewater samples using 24-hour flow-proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is authorized by Public Works Director. Where time-proportional composite sampling or grab sampling is authorized by the city, the samples must be representative of the discharge. Using protocols (including appropriate preservation) specified in 40 C.F.R. Part 136 and appropriate EPA guidance, multiple grab samples collected during a 24-hour period may be composited prior to the analysis as follows: for cyanide, total phenols, and sulfides the samples may be composited in the laboratory or in the field; for volatile organics and oil and grease, the samples may be composited in the laboratory. Composite samples for other parameters unaffected by the compositing procedures as documented in approved EPA methodologies may be authorized by the city, as appropriate. In addition, grab samples may be required to show compliance with instantaneous limits.
B. Samples for oil and grease, temperature, pH, cyanide, total phenols, sulfides, and volatile organic compounds must be obtained using grab collection techniques.
C. For sampling required in support of baseline monitoring and 90-day compliance reports required in §§ 13.16.090 and 13.16.092 [40 C.F.R. 403.12(b) and (d)], a minimum of 4 grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide and volatile organic compounds for facilities for which historical sampling data do not exist; for facilities for which historical sampling data are available, the Public Works Director may authorize a lower minimum. For the reports required by § 13.16.093 [40 C.F.R. 403.12(e) and 403.12(h)], the industrial user is required to collect the number of grab samples necessary to assess and assure compliance by with applicable pretreatment standards and requirements.
D. Samples that are taken by city personnel for the purposes of determining compliance with the requirements of this chapter may be split with the discharger if requested (or a duplicate sample provided in the instance of fats, oils and greases) if requested before or at the time of sampling.
E. The Public Works Director or other designee may require a discharger to install and maintain at the discharger's expense a suitable manhole in the discharger's branch sewer or other suitable monitoring access to allow observation, sampling and measurement of all industrial wastes being discharged into the city sewer system. It shall be constructed in accordance with plans approved by the city and shall be designed so that flow measuring and sampling equipment may be conveniently installed. Access to the manhole or monitoring access shall be available to city representatives at all times.
(Ord. 1413 § 6.8, passed 4-1-2015)
All sample analyses shall be performed in accordance with the procedures set forth in 40 C.F.R. Part 136 and any amendments thereto or with any other test procedures approved by the Administrator of The Environmental Protection Agency. If there are no approved test procedures for a particular pollutant, then analyses shall be performed using other validated procedures approved by the Public Works Director or other designee and, if the discharge is subject to a categorical pretreatment standard, by the EPA Administrator.
(Ord. 1413 § 6.9, passed 4-1-2015)
Industrial users shall retain, and make available for inspection, and copying, all records and information required to be retained under 40 C.F.R. 403.12(o), (including documentation associated with best management practices). These records shall remain available for a period of at least 3 years. This period shall be automatically extended for the duration of any litigation concerning compliance with this chapter, or where the industrial user has been specifically notified of a longer retention period by the Public Works Director or other designee, DEQ or EPA.
(Ord. 1413 § 6.12, passed 4-1-2015)
If an industrial user subject to the reporting requirements of 40 C.F.R. 403.12(e) or (h), which requires submission of periodic compliance reports, monitors any pollutant more frequently than required by the city, using the procedures prescribed in 40 C.F.R. Part 136, the results of this monitoring shall be included in the report, as required by 40 C.F.R. 403.12(g)(5).
(Ord. 1413 § 6.13, passed 4-1-2015)
An industrial user operating under a waste discharge permit incorporating equivalent mass or concentration limits calculated from a production based standard shall notify the Public Works Director or other designee within 2 business days after the user has a reasonable basis to know that the production level will significantly change within the next calendar month. Any user not notifying the Public Works Director or other designee of such anticipated change shall be required to meet the mass or concentration limits in its permit that were based on the original estimate of the long term average production rate.
(Ord. 1413 § 6.14, passed 4-1-2015)
