Shasta County Municipal Code Div. III Prevention and Reduction of Pollutants in Storm Water

A. The resource management or public works director and/or state or federal agencies may designate as subject activities any activities, including construction and industrial activities, considered potential sources of discharges of pollutants to the county storm water conveyance system or receiving waters. The subject activity may occur at stationary facilities or as a mobile activity that takes place at various job sites. State or federal agencies may require the county to enforce regulatory measures against the subject activity in question.

B. Industrial activities for which the MS4 permit specifies that the county shall routinely inspect, or which are listed in MS4 Permit Section E.9. are hereby designated as subject activities.

(Ord. No. 2016-03, § I, 4-26-2016)

A. Any person whom the resource management or public works director determines is conducting any subject activity shall prevent or reduce the discharge of pollutants from those activities, to the MEP, through the implementation of BMPs.

B. The resource management director may require any business in the county that is engaged in activities that may result in non-storm water or pollutant discharges to develop and implement a SWPPP in accordance with the requirements established by the resource management director,

C. The resource management or public works director may adopt standards or requirements and describe BMPs for specified subject activities. Where BMP requirements are promulgated by the county or any federal, state, or regional agency for any activity, operation, or facility which would otherwise cause the discharge of pollutants to the county storm water conveyance system or receiving waters, every person undertaking such activity or operation, or owning or operating such facility shall comply with such requirements.

D. Any alternative BMP implemented pursuant to subsection (C) of this section shall be subject to review and approval by the resource management director or public works director. If a person conducting subject activities implements alternative BMPs without the prior written approval of the resource management director or public works director and subsequently receives written notice from the resource management director or public works director that the alternative BMPs do not provide the required equivalent level of protection from pollutant-laden storm or exempted non-storm water discharges, the continued implementation of such alternative BMPs shall be deemed to be a violation of requirements of this chapter as of the date of delivery of such notice.

E. Notwithstanding the presence or absence of requirements promulgated pursuant to subsections (A), (B) and (C) any person engaged in activities or operations, or owning facilities or property which will or may result in pollutants entering the county storm water conveyance system or receiving waters shall implement BMPs to the MEP.

F. Persons implementing BMPs will be required to establish, document, and conduct a maintenance program, subject to approval by the resource management or public works director, for any BMP. This requirement applies to BMPs required by the county and BMPs that were voluntarily installed. Maintenance requirements established pursuant to this section must be appropriate for site conditions, design of the BMPs, and must protect public safety, health, infrastructure, the environment and meet the purposes of this chapter.

(Ord. No. 2016-03, § I, 4-26-2016)

A. The owner or operator of a commercial or industrial establishment shall provide reasonable protection from accidental discharge of pollutants into the county storm water conveyance system or receiving waters. Facilities to prevent accidental discharge of pollutants shall be provided and maintained at the owner or operator's expense.

B. The resource management director may designate types of industries where the owner or operator of the industry shall be required to notify the resource management director within twenty-four hours of the discovery of an actual discharge into the county storm water conveyance system. For any discharge subject to the reporting requirements of the State of California Water Code Sections 13271 and 13272, notification in compliance therewith shall constitute sufficient notification for the purposes of this section.

C. Any person owning or occupying premises or conducting any activity that has knowledge of any non-storm water discharge or threatened prohibited discharge, from the premises or activity to the county storm water conveyance system or receiving waters shall immediately take all reasonable action to contain and otherwise minimize any such discharge.

D. Notwithstanding other requirements of law, as soon as any person responsible for a facility or operation, or responsible for emergency response for a facility or operation, has information of any known or suspected release of pollutants from said facility or operation which are resulting or may result in illicit discharges or pollutants discharging into the county storm water conveyance system or receiving waters, said person shall take all necessary steps to ensure the discovery, containment, and cleanup of such release. In the event of such a release of a hazardous material, said person shall immediately notify emergency response officials of the occurrence via emergency dispatch services (911). In the event of such a release is of non-hazardous materials and not an emergency, said person shall notify the resource management and public works departments in person or by phone no later than 3:00 p.m. of the next business day. If the discharge of pollutants emanates from a commercial or industrial establishment, the owner or operator of such establishment shall also retain an on-site written record of the discharge and the actions taken to prevent its recurrence. Such records shall be retained for at least threeyears.

(Ord. No. 2016-03, § I, 4-26-2016)

Notwithstanding the requirements of Division III herein, the resource management or public works director may require by written notice that a person responsible for a prohibited discharge immediately, or by a specified date, discontinue the discharge and, if necessary, take measures at the cost of the discharger to eliminate the source of the discharge to prevent the occurrence of future illicit discharges.
