Palo Alto Municipal Code § 16.13.010 Purpose and intent

The purpose of this chapter is to control and limit impacts from fats, oils, and grease (FOG) generated by food facilities to the City of Palo Alto (city) storm drain system, sanitary sewer system, right-of-way, and receiving waters, including the San Francisco Bay (bay) and local creeks, marshes, wetlands and other natural habitats, as well as to protect human health and the environment. This chapter is enacted and shall be implemented in a manner consistent with the U.S. Environmental Protection Agency "General Pretreatment Regulations for Existing and New Sources of Pollution" published at Title 40 of the Code of Federal Regulations, Part 403, the Porter-Cologne Water Quality Control Act (Water Code Section 13000 et seq.), and the Federal Clean Water Act (33 U.S.C. Section 1251 et seq.) (CWA), as amended from time to time. This chapter is designed to be no less stringent than regional, state or federal regulations, rules, orders, and policies but in some respects is more stringent. The city intends to update and modify this chapter as needed to continue to meet state and regional requirements and provide a program for protection of the San Francisco Bay and other receiving waters. If any provision of this chapter conflicts with state or regional requirements, as amended or updated, the more stringent and environmentally protective provision shall apply. This chapter supplements the provisions of Chapters 16.09 and 16.11 of the Palo Alto Municipal Code, which apply to uses and activities in the city more broadly, as well as food facilities. This chapter is intended to complement, rather than supersede, the provisions of city building codes and regulations applicable to the installation and operation of grease capturing equipment.
