Pollutants are total and in mg/l unless otherwise sEecified. B. The above limits apply at the point where the wastewater is discharged to the POTW (end of pipe). The superintendent may impose mass limitations in addition to (or in place of) the concentration based limitations above. Where a user is subject to a categorical pretreatment standard and a limit for a given pollutant, the more stringent limit of applicable pretreatment standard shall apply. C. The following limits shall apply to wastewaters that are discharged from the groundwater cleanup of petroleum or gasoline underground storage tanks or other remediation wastewaters containing these pollutants or where these pollutants are appropriate surrogates. It shall be unlawful for any industrial user to discharge or cause to be discharged any waste or wastewater to the POTW that exceeds the following limits, as applicable: D E.

Whenever deemed necessary, the superintendent may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sanitary sewers, relocate and/or consolidate points of discharge, separate sewage waste streams from industrial waste streams, and such other conditions as may be necessary to protect the POTW and determine the user's compliance with the requirements of this chapter. The superintendent may require any person discharging into the POTW to install and maintain, on their property and at their expense, a suitable storage and flow control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization. A grease interceptor or a grease trap is not considered to be properly maintained if for any reason it is not in good working condition with all internal required plumbing of proper design and length in place, or if the operational fluid capacity has been reduced by more than twenty five percent (25%) by the accumulation of floating and settled solids, oils, and greases. The owner of any premises required to install a grease interceptor; the lessee and sublessee, if there be such; and any proprietor, operator, or superintendent of such facility are individually and severally liable for any failure of proper maintenance of such grease interceptor. If the grease interceptor is not maintained adequately under the conditions of use, the grease interceptor shall be resited and the user shall install one which is effective in accomplishing the intended purpose. When a grease interceptor/trap is cleaned, the sidewalls should be scraped and hosed down, while all the solids and liquids contained are removed. All wastes removed from any grease interceptorltrap shall be legally disposed of other than to the sewer. The city of Chubbuck specifically prohibits the following grease interceptor/trap practices; 1. Pumping to remove only accumulated sediments or floating materials; 2. Pumping operations which specifically separate floating or sediment interceptor solid wastes from wastewater and then return or decant the separated wastewater back into the grease interceptor/trap; 3. Transporting any hauled pollutants from another location for discharge into a grease interceptor/trap. 4. Use of grease interceptor/trap treatment products, including bacteria, designed to digest the grease, ^is specifically prohibited. Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter. 13.20.090: SEPTIC TANK WASTE: A. Septic tank waste may be introduced into the POTW only at the designated receiving structure within the treatment plant area, located at 10733 N. Rio Vista Road, and at such times as are established by the superintendent of the POTW. No other point of discharge within the city's collection system will be allowed without the expressed written permission of the superintendent. The discharge of any hauled waste to a point in the city's collection system, other than as specifically designated by the superintendent, shall be deemed a violation of these regulations and shall be subject to enforcement action. Such wastes shall not violate any section of this chapter or any other requirements established or adopted by the city. B. All domestic septic tank waste, portable toilet waste or other hauled waste deemed acceptable by the superintendent will be subject to the terms and conditions contained in the city's general regulations of waste haulers, incorporated herein and made a part thereof. Ordinance - Page 13 chubbuck 641521 pretrealemnl ord.wpd C. Discharges of nondomestic hauled waste shall be subject to the applicable prohibited discharges as set forth in sections 13.20.030 through 13.20.045 of this chapter, as well as any applicable federal, state and local regulations goverrnng Fara waste or any conditions the superintendent deems necessary for protection of its treatment works. Nothing contained in these regulations shall be construed as being preemptory of any other regulations governing hauled waste, or waste haulers, or any business activities pertaining to hauled waste, or as set forth in any federal, state or local guidance governing hauled waste. E. Any waste hauler seeking to discharge hauled waste to the POTW, or to any designated point within the city collection system, must have a city approved waste hauler's permit. No load may be discharged without prior consent of the superintendent of the POTW. The superintendent may collect samples of each hauled load to ensure compliance with applicable pretreatment standards. The superintendent may require the hauler to provide a waste analysis of any load prior to discharge. The superintendent reserves the right to refuse permission to dump any load that is suspected of being incompatible or that is determined to be incompatible with the POTW through sampling and analysis, or sound professional judgment. Waste haulers mustprovide a waste tracking form for every load. A waste tracking form approved by the POTW shall be used to record every load that is delivered to the POTW. Failure to accurately record every load, falsification of data or failure to transmit the form to the superintendent prior to discharge into the POTW may result in revocation of this permit. 13.20.120: WASTEWATER DISCHARGE PERMIT APPLICATION CONTENTS: All users required to obtain a wastewater discharge permit must submit, at a minimum, the following information. The superintendent shall approve a form to be used as a permit application. Categorical users submitting the following information shall have complied with 40 CFR 403.12(b). A.

Each user shall provide and operate at its own expense a monitoring facility to allow inspections, sampling, and flow measurements of each sewer discharge to the city. Each monitoring facility shall be situated on the user's premises, except, where such a location would be impractical or cause undue hardship on the user, 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. The superintendent, whenever applicable, may require the construction and maintenance of sampling facilities at other locations (for example, at the end of a manufacturing line or a wastewater treatment system). There shall be ample room in or near such sampling facility to allow accurate sampling and preparation of samples for analysis. The facility, including the sampling and measuring equipment, shall be maintained at all times in a safe and proper operating condition at the expense of the user. C.

Accordingly, the industrial user shall be apprised that noncompliance with this cha ter and its wastewater discharge permit ma lead to an en orcement action and may result in a kation o its name in appropriate news a er in accordance with the section. For the purposes of this provision, a user is in significant noncompliance it its vio atlon meets one or more of the following criteria: A. Chronic violations of wastewater discharge limits, defined herein as those in which sixty six percent (66%) or more of measurements taken for the same pollutant parameter during a six (6) month period exceed (by any magnitude) a numeric pretreatment standard or requirement including instantaneous limits, as defined by 40 CFR 403.3(1); B.
