Article X — REGULATION OF DISCHARGE INTO CITY SEWER SYSTEM

Sec. 29.143. - Pretreatment of wastewater.

Oceanside Municipal Code · 2026-09 edition · updated 2026-09-27 · Oceanside

29.143.1.

Pretreatment facilities. Users shall provide wastewater treatment as necessary to comply with this

article and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in section 29.131 of this article within the time limitations specified by EPA, the state, or the water utilities director, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at the user's expense. Detailed plans describing such facilities and operating procedures shall be submitted to the water utilities director for review, and shall be acceptable to the water utilities director before such facilities are constructed. The review of such plans and operating procedures shall in no way relieve the user from the responsibility of modifying such facilities as necessary to produce a discharge acceptable to the city under the provisions of this article.

29.143.2. Additional pretreatment measures.

A.

Whenever deemed necessary, the water utilities director may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial wastestreams, and such other conditions as may be necessary to protect the POTW and determine the user's compliance with the requirements of this article.

B.

The water utilities director may require any person discharging into the POTW to install and maintain, on that person's property and at that person's expense, a suitable storage and flow-control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization.

C.

Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.

29.143.3.

Accidental discharge/slug discharge control plans. At least once every two (2) years, the water

utilities director shall evaluate whether each significant industrial user (SIU) needs an accidental discharge/slug discharge control plan or other action to control slug discharges. The water utilities director may require any user to develop, submit for approval, and implement such a plan or take such other action that may be necessary to control slug discharges. An accidental discharge/slug discharge control plan shall address, at a minimum, the following:

A.

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

B.

Description of stored chemicals;

C.

Procedures for immediately notifying the water utilities director of any accidental or slug discharge, as required by section 29.146.6 of this article; and

D.

Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures 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.

29.143.4.

Toxic organics management plan. The city may require any user to submit a toxic organic

management plan (TOMP) to address the prevention of discharge of toxic organics to the city's sewerage system or the environment. A TOMP shall contain, at a minimum, the toxic organic compounds used, the method(s) of disposal, and the procedures for assuring that toxic organics do not spill into the wastewater being discharged. The water utilities director may allow a user to develop and implement a TOMP in lieu of required self-monitoring for toxic organics.

29.143.5.

Spill containment facilities. All users shall provide, maintain and pay for spill containment facilities

to protect against discharge in violation of this article. Spill containment facilities shall be designed to secure one hundred ten (110) percent of the capacity of the tank(s) within the structure and prevent it from entering the city's sewerage system, in accordance with reasonable engineering standards.

29.143.6. Bypass.

A.

No discharger shall "bypass" or intentionally divert wastestream from any portion of an industrial user's treatment system, unless:

(1)

Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;

(2)

There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass that occurred during normal periods of equipment downtime or preventive maintenance; and

(3)

The industrial user submitted the notices discussed below.

B.

The water utilities director may approve an anticipated bypass only after considering its adverse effects, and if the water utilities director determines:

(1)

The bypass will not cause violation of pretreatment standards or requirements or any provision of this article; and

(2)

The bypass is for essential maintenance to ensure the efficient operation of pretreatment systems.

C.

If an industrial user knows in advance of the need for bypass, the user shall submit a written notice to the water utilities director at least ten (10) business days before the date of the bypass, and shall not permit the bypass without the water utilities director's authorization.

D.

An industrial user shall submit oral notice to the water utilities director of an unanticipated bypass that exceeds applicable pretreatment standards or requirements, immediately upon becoming aware of the bypass. Additionally, the industrial user shall submit within five (5) business days of oral notification, a written report describing the bypass event and its cause; the bypass duration, including exact times and dates; and if the bypass has not been corrected, the time it is expected to continue and measures taken to reduce, eliminate, and prevent its recurrence.

E.

Notification of bypass shall not relieve the user of any expense, loss, damage or other liability that may be incurred as a result of damage or loss to the city or any other damage or loss to person or property; nor shall such notification relieve the user of any fees or other liability that may be imposed by this article or other applicable law.

F.

Users shall control production of all discharges to the extent necessary to maintain compliance with categorical pretreatment standards upon reduction, loss, or failure of its treatment facility until the facility is restored or an alternative method of treatment is provided. This requirement applies in the situation where, among other things, the primary source of power of the treatment facility is reduced, lost, or fails.
