Section 5 <br />Non-Priority Projects <br />Certain projects that do not meet the Priority Project criteria are considered Non- <br />Priority Projects and require preparation of Non-Priority Project Plans (NPP). The <br />Non-Priority Project Plan requires documentation of the selection of site design <br />features, source control and any other BMPs included in a project. <br />Section 404: Section 404 of the Clean Water Act established a permitting <br />program to regulate the discharge of dredged or filled material into waters of the <br />United States. The permitting program is administered by the US Army Corps of <br />Engineers and is enforced by the Environmental Protection Agency. <br />Section 303 (d)- Under Section 303 (d) of the Clean Water Act, the SWRCB is <br />required to develop a list of impaired water bodies, Each RWQCB is responsible <br />for establishing priority rankings and developing action plans, referred to as total <br />maximum daily loads (TMDLs) to improve water quality of water bodies included <br />in the 303(d) list. Presently, Santa Ana River Reach 2 (17tt" Street in Santa Ana <br />to Prado Dam) has been listed as impairment for indicator bacteria. The TMDLs <br />for the Santa Ana River Reach 2 is required, to be prepared before 2025. The <br />Santa Ana River Reach 1 (Pacific Ocean to 171" Street in Santa Ana) is not listed <br />as impaired. <br />Safe Drinking Water Act <br />The Safe Drinking Water Act (SDWA) was established to protect the quality of <br />drinking water in the United States. This law focuses on all waters actually or <br />potentially designed for drinking use, whether from above or below ground <br />sources. The SDWA and subsequent amendments authorize EPA to establish <br />health-based standards, or maximum contaminant levels (MCLs), for drinking <br />water to protect public health against both natural and anthropogenic <br />contaminants. All owners or operators of public water systems are required to <br />comply with these primary (health-related) standards, State governments, which <br />can be approved to implement these rules for EPA, also encourage attainment of <br />secondary (nuisance-related) standards. At the Federal level, EPA administers <br />the SDWA and establishes MCLs for bacteriological, organic, inorganic, and <br />radiological constituents. At the State level, California has adopted its own <br />SDWA, which incorporates the federal SDWA requirements with some <br />requirements specific only to California. The 1996 SDWA amendments <br />established source water assessment (SWA) programs pertaining to untreated <br />water from rivers, lalkes, streams, and groundwater aquifers used for drinking <br />water supply. According to these amendments, EPA must consider a detailed <br />risk and cost assessment, as well as best available peer-reviewed science, when <br />developing standards for drinking water. These programs are the foundation of <br />tL Mid Basin Centennial Park Ae_ldi Project Final EIR 5-102 <br />
