of Santa Ana Section 3: Legal A Through a series of Ordinances and Resolutions adopted by the City Council and internally developed Plans and Requirements, the City possesses the necessary legal authority required by Section D-3 Legal Authority of Order No. 2022-0103 DWQ: 1) The City of Santa Ana has the power to install sewers and enact regulations related thereto, including the regulation of discharges from private property. Section 39-57 of the Municipal Codestates: "All City -owned sewer lines and private onsite sewer lines and laterals should be constructed and maintained to prevent water infiltration into the sewer system. Private on -site sewer lines and public sewer lines shall be used only to convey raw sewage. Rainfall runoff sources (including, but not limited to roof drains, site drains, inlets, uncovered wash area drains, etc.) are prohibited from connecting to any public or private sanitary sewer pipeline." The City of Santa Ana currently enforces Orange County Sanitation District (OC San) regulations prohibiting the discharge of rainfall to the sewer system. This is done through the City's existing development approval process. No connections from any potential source of runoff are allowed to the City's sanitary sewer system. 2) The City of Santa Ana has the legal authority to collaborate with storm sewer agencies to coordinate emergency spill responses, ensure access to storm sewer systems during spill events, and prevent unintentional cross connections of sanitary sewer infrastructure to storm sewer infrastructure. 3) The City prevents illicit discharges into its sanitary sewer system (including, but not limited to, infiltration and inflow (1/1), unauthorized stormwater, chemical dumping, and unauthorized debris) through the City Municipal Code, Chapter 39, Section 39-57, Infiltration and inflow into sewer system, Section 39-58, Introduction of pollutants prohibited and Ordinance No. NS-2921. 4) The City of Santa Ana has standard plans and specifications for the construction of sanitary sewers, which ensure the sewer system components and connections are properly designed and constructed. The Design Guidelines for Water and Sewer Facilities are available on the City's website. Also, the City's Specifications by reference incorporate the Standard Plans and Specifications for Public Works Construction (Green Book), which ensure the proper design and construction of sewer facilities. 5) The City of Santa Ana has a full time Construction Engineering section responsible for oversight of city construction projects. A staff of full-time engineers and inspectors are responsible for ensuring all city projects, including sanitary sewer improvements, are constructed in compliance with approved plans and specifications. 6) In November of 2001, the City of Santa Ana via Ordinance No. NS-2479 implemented a sewer lateral repair program. The City repairs and/or replaces the portion of damaged sewer laterals located within the public right-of-way. This work is accomplished by experienced in-house field maintenance personnel. 7) The City of Santa Ana recognizes the significant impacts to sewer collection system operation caused by fats, oils and grease (FOG) and trash, including rags and other debris that may cause blockages. In November of 2017, the City adopted a comprehensive FOG control ordinance (Ordinance No. NS 2921). This ordinance updated an already established legal authority requirement to implement a comprehensive FOG control program. The ordinance is attached as Appendix E. 2025 3-2
