BACKGROUND & HISTORY:
On June 2, 2017, the Santa Ana Regional Water Quality Control Board (Santa Ana Regional Board) notified the City of Corona that the State Water Board adopted statewide Trash Provisions to address the impacts trash has on the beneficial uses of surface waters. Throughout the state, trash is typically generated on land and transported to surface water, predominantly through municipal separate storm sewer system (MS4) discharges. Within the jurisdiction of the Santa Ana Regional Board, these discharges from Riverside County’s Phase I MS4s are regulated through the Riverside County MS4 Permit (Order No. R8-2010-0033 NPDES No. CAS618033, as amended by Order No.
R8-2013-0024) pursuant to section 402(p) of the Federal Clean Water Act.
The Trash Provisions require MS4 permittees with regulatory authority over Priority Land Uses to select a method of compliance with the trash prohibition. To ensure catch basin locations are selected accurately, the Santa Ana Regional Board recommended each permittee develop maps identifying priority land use areas within their jurisdiction, the corresponding storm drain network and associated drainage areas, and proposed locations for certified full capture system installations. On August 29, 2017, the City of Corona responded, providing the selection to install, operate, and maintain full capture systems for all storm drains that capture runoff from Priority Land Uses in their jurisdictions.
This project is the first phase to install 220 out of 1,200 trash-capturing devices throughout the city’s catch basins that fall within the identified priority land use areas to comply with the Santa Ana Regional Board. The City previously piloted an installation of 4 trash capture devices in Winter 2022 to identify the product that would meet the requirements designated by the State Water Board. The devices are required as part of the MS4 permit and will be included in the new Tri-County MS4/NPDES Permit anticipated to be adopted in year 2025. Compliance with this requirement must be achieved by 2030. The project budget is for device installation only and does not include maintenance costs. This first phase is funded by the City’s County Service Area 152 (NPDES) Fund 245. In a prior year, the City applied to the Riverside County Flood Control and Water Conservation District’s annual call for projects and was successfully awarded $1 million to fund the next phase of the project. The agreement is currently being finalized and will be coming to a future Council meeting for acceptance. Completing the project will help the City meet the Strategic Plan goals for Sound Infrastructure by making necessary improvements to sustain high-quality service delivery by investing in public infrastructure while also meeting the State’s unfunded mandate.
