Buellton Municipal Code Ch. 14.56 Pretreatment of Industrial Wastewater

A. No user shall discharge wastewater not in compliance with the limitations of this title to the sewer system. Each user shall provide wastewater pretreatment as necessary to comply with this title and shall achieve compliance with all categorical pretreatment standards, local limits and the prohibitions set out in this chapter within the time limitations specified by EPA, the state, or the public works director, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at user's expense. Detailed plans describing such facilities and operating procedures shall be submitted to the public works director for review, and shall be approved by the public works director before such facilities are constructed. The review of such plans and operating procedures will in no way relieve the user from the responsibility of modifying the facility as necessary to produce a discharge in compliance with the provisions of this chapter.

B. Pretreatment facilities shall be constructed and maintained in good working order, and operated as efficiently as possible, at the expense of the discharger, subject to the requirements of this title and all other applicable codes and laws.

(Ord. 03-03 § 7, 2003)

A. Whenever deemed necessary to protect the wastewater system or public health and safety, the public works director may require a user to restrict the user's discharge, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate domestic wastestreams from industrial wastestreams, and such other conditions as may be necessary to determine the user's compliance with the requirements of this chapter.

B. The public works director may require any person discharging into the system to install and maintain, on the user's property and at the user's expense, a suitable storage and flow-control facility to ensure active management of flow. An IWD permit may be issued solely for flow regulation.

C. A user, at user's sole expense, shall provide, install and maintain one or more gravity separation devices when, in the opinion of the public works director, they are necessary for the proper handling of wastewater containing excessive amounts of oil and grease or sand that exceed discharge limitations set forth in this title. All gravity separation devices shall be of a type and capacity approved by the public works director and shall be located so as to be easily accessible for cleaning and inspection. Such devices shall be inspected, cleaned, and repaired regularly, as needed, by the user at user's expense.

D. The public works director may require any user with the potential to discharge flammable substances to install and maintain an approved combustible gas detection meter.

(Ord. 03-03 § 7, 2003)

A. Each industrial user shall prevent accidental discharge of prohibited materials or other wastes regulated by this title. Facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the user's expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the city for review and shall be approved by the city before construction of the facility. Review and approval of such plans and operating procedures shall not relieve the industrial user from the responsibility to modify his or her facility as necessary to meet the requirements of this title or of any other applicable rule, regulation, order or ordinance of a governmental authority.

B. An accidental discharge/control slug plan shall address, at a minimum, the following:

1. Description of discharge practices, including non-routine batch discharges;

2. Description of stored chemicals;

3. Procedures for immediately notifying the public works director of any accidental or slug discharge; and

4. Procedures to prevent adverse impacts from any accidental or slug discharge. Such procedures shall include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents, and/or measures and equipment for emergency response.

(Ord. 03-03 § 7, 2003)

When requested by the public works director, an industrial user shall submit information on the nature and characteristics of its raw wastewater within 30 days of the request, in a format prescribed by the public works director.

(Ord. 03-03 § 7, 2003)

Prior to discharging wastewater to the system, a user required to install pretreatment or monitoring facilities, shall submit detailed plans to the city for review showing the pretreatment facility and operating procedures before construction of the facility. All such plans and construction shall be prepared at the user's expense. The city's review and approval of such plans and operating procedures will in no way relieve the user from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the city under the provisions of this title, and the user shall remain responsible for compliance with all applicable codes, regulations and orders of any governmental authority. Any subsequent proposed changes in the pretreatment facilities or methods of operation shall be submitted to and, if appropriate, approved by the city prior to user's implementation of the changes. Permits for facility construction are required as set forth in this title.

(Ord. 03-03 § 7, 2003)

When required by the city, a sampling station of a design and location to facilitate inspection, sampling and flow measurements, approved by the city, shall be furnished and installed by the user, at the user's expense. Each user shall provide the city with unrestricted access to its sampling station at all times.

(Ord. 03-03 § 7, 2003)

When a defect results from improper installation, or installation of sewer facilities with materials not meeting city standards, the person responsible for the defect shall correct it at that person's sole expense.

(Ord. 03-03 § 7, 2003)

A. Each industrial user shall immediately notify the city of any discharge that could cause a plant upset or pass-through or other problem to the POTW, including any slug loading or accidental discharge. Each user shall post notices in prominent locations, such as bulletin boards, lunchrooms, and other places as appropriate, advising employees whom to call in the event of an accidental discharge. Users shall ensure that all employees who may cause such an accidental discharge are advised of the emergency notification procedure.

B. Any person who causes an accidental discharge or who discovers an uncontrolled discharge that does not comply with this title, shall immediately notify the city so that corrective action may be taken to protect the system.

C. In addition to the immediate notification requirements imposed by Section 14.56.090.A and B, above, a user responsible for an accidental discharge shall file a written report with the city detailing the date, time and cause of the accidental discharge, the quantity and characteristics of the discharge, cleanup and response actions taken and corrective action taken to prevent future discharges. The report shall be filed with the city by the responsible industrial user within five calendar days of the occurrence of the discharge (40 C.F.R. Section 403.12(f)).

D. Such notification will not relieve users of liability for any expense, loss or damage to the sewer system, treatment plant or treatment process, or for any fines imposed on the city on account thereof under Section 13350 of the California Water Code or for violations of Section 5650 of the California Fish and Game Code, or any other applicable state or federal statute or regulation.
