A. Authorization to Adopt and Impose Best Management Practices. The city will adopt requirements identifying best management practices for any activity, operation, or facility which may cause or contribute to pollution or contamination of storm water, the storm drain system, or waters of the United States as a separate BMPs Guidance Series. Where best management practices requirements are promulgated by the city or any federal, state of California, or regional agency for any activity, operation, or facility which would otherwise cause the discharge of pollutants to the storm drain system or waters of the United States, every person undertaking such activity or operation, or owning or operating such facility shall comply with such requirements.

The public works director will report to the city council annually on the status of implementation of BMPs, the pollutants of concern to be addressed the next year, and any new BMPs to be developed. BMPs developed under this program will be included in the city of Wasco’s BMPs Guidance Series.

B. New Development and Redevelopment. The city may adopt requirements identifying appropriate best management practices to control the volume, rate, and potential pollutant load of storm water runoff from new development and redevelopment projects as may be appropriate to minimize the generation, transport, and discharge of pollutants. The city shall incorporate such requirements in any land use entitlement and construction or building-related permit to be issued relative to such development or redevelopment. The owner and developer shall comply with the terms, provisions, and conditions of such land use entitlements and building permits as required in this chapter, the city building and construction ordinance, Title 15, Chapter 15.04, and Title 17, Zoning.

C. Responsibility to Implement Best Management Practices. Notwithstanding the presence or absence of requirements promulgated pursuant to subsections A and B of this section, any person engaged in activities or operations, or owning facilities or property which will or may result in pollutants entering storm water, the storm drain system, or waters of the United States shall implement best management practices to the extent they are technologically achievable to prevent and reduce such pollutants. The owner or operator of a commercial or industrial establishment shall provide reasonable protection from accidental discharge of prohibited materials or other wastes into the municipal storm drain system or watercourses. Facilities to prevent accidental discharge of prohibited materials or other wastes shall be provided and maintained at the owner or operator’s expense.

Best management practices required by the city can be obtained from the public works department by requesting the BMPs manual appropriate to a commercial or industrial activity from the BMPs Guidance Series. BMPs are broken into three categories: high priority, which are required to be implemented; medium priority, which are desirable to implement; and low priority. (Ord. 713 §1, 2020).
