Santa Ana Region Storm Water Unit

Storm Water Unit

Stormwater runoff regulation in the Santa Ana Regional Water Quality Control Board (Santa Ana Water Board) is enforced by the Coastal Stormwater Unit and the Inland Stormwater Unit.  The Coastal Stormwater Unit administers the Phase I and Phase II municipal separate storm sewer system (MS4) permits, the Industrial General Permit, and the Construction General Permit programs for the area of Orange County within the Region.  The Coastal Stormwater Unit also administers the Scrap Metal Permit and the Caltrans MS4 Permit programs for the entire Region. The Inland Stormwater Unit administers the Phase I and Phase II MS4 permits, and the Industrial and Construction General Permit programs for the areas of Riverside and San Bernardino counties within the Region.

The units regulate storm water and non-storm water discharges to waters of the U.S., including storm drains, rivers, streams, lakes, wetlands and the ocean. The Clean Water Act requires the State/Regional Boards to regulate the discharge of storm water from many sources. For the Phase I MS4 program, these sources included large (population greater than 250,000) and medium (population from 100,000 to 250,000) sized municipalities, most industrial sites, and construction activities on one acre or more. For the Phase II program, this includes public universities, large state and federal institutions, and certain state parks.

Stormwater permits implement the Clean Water Act’s NPDES program, state water quality control plans and the Region’s Basin Plan. The Basin Plan implements Total Maximum Daily Loads. The stormwater permits implement those parts of TMDLs where the discharger has been assigned a waste load allocation.

Stormwater permits are issued on a statewide basis or a regional basis and are enforced by the local regional board. The State Water Resources Control Board (SWRCB) issued two General Permits (Stormwater Industrial General Permit and Stormwater Construction General Permit) to address most of the industrial facilities and the construction sites within California. In addition, the SWRCB issued two state-wide Municipal Permits, the Caltrans MS4 Permit and the Phase II MS4 Permit. These General Permits are available at the SWRCB's Storm Water Website.

The Santa Ana Water Board adopted a sector-specific General Permit for storm water discharges from certain industrial facilities identified by the Standard Industrial Classification (SIC) Code 5093, specifically identifying metal scrap recyclers (excluding recycling facilities that only receive recyclable materials where no processes are performed on the metal scrap other than sorting, compaction, storage and transport).

The Santa Ana Water Board has also issued a TMDL-specific permit for the cities of Claremont and Pomona, Order No. R8-2013-0043, NPDES Permit No. CA8000410. This Order implements the Bacterial Indicator TMDL for the Middle Santa Ana River watershed.

Information on the Statewide stormwater permits may be obtained at the SWRCB's Storm Water Website. For information on facilities covered by individual permits issued by the Santa Ana Water Board or to review the files for the facilities covered either by the General Permits or by individual permits, please contact the file review desk at FileReview8@waterboards.ca.gov.  Information can also be obtained through public user menu for the Stormwater Multiple Application and Report Tracking System (SMARTS).

The Santa Ana Water Board has issued three MS4 permits to the three counties (Orange, Riverside, and San Bernardino) and all the incorporated cities within the jurisdiction of this Board.  Santa Ana Water Board staff is developing a draft Regional MS4 Permit to replace the three permits.  Please use the tabs below to view additional information.


Notice of Workshop on Staff Working Proposal for NPDES Permit and Waste Discharge Requirements for Discharges of Pollutants in Urban Runoff from the Municipal Separate Storm Sewer Systems in the Counties of Orange, Riverside, and San Bernardino (NPDES No. CAS618000)  – Staff of the Santa Ana Water Board has released a staff working proposal for regulating discharges of pollutants in urban runoff from Municipal Separate Storm Sewer Systems (MS4s) in Orange, Riverside, and San Bernardino Counties on a regionwide basis.  An overview of the Region’s stormwater program and key provisions of the staff working proposal will be provided, as well as an opportunity for feedback on the staff working proposal from permittees and other stakeholders.  The Board may provide input to staff on the working proposal; however, no action or voting will be taken.  Staff Working Proposal

Santa Ana Water Board staff is proposing that the Santa Ana Regional Water Quality Control Board adopt a region-wide Phase I MS4 Permit.  This permit would be adopted to  replace the three MS4 permits for Orange, Riverside, and San Bernardino counties in the Region.  The Orange County permit was adopted in 2009 and the permits for Riverside and San Bernardino counties were adopted in 2010.  The permittees have submitted their reports of waste discharge. The permits were administratively extended in 2014 and 2015 and remain in effect until a new permit is adopted by the Santa Ana Water Board.

To review the reports of waste discharge, please contact the file review desk at FileReview8@waterboards.ca.gov.

For additional information regarding the proposed region-wide Phase I MS4 Permit, please contact Ray Akhtarshad (951 320-2024) or Steven Stephansen (951 320-2027).

To receive updates about the proposed Regional MS4 Permit and other stormwater program-related information, please join a municipal stormwater e-mail list subscription.

Dischargers whose projects disturb one (1) or more acres of soil or whose projects disturb less than one acre but are part of a larger common plan of development that in total disturbs one or more acres, are required to obtain coverage under the General Permit for Discharges of Storm Water Associated with Construction Activity Construction General Permit Order 2009-0009-DWQ. Construction activity subject to this permit includes clearing, grading and disturbances to the ground such as stockpiling, or excavation, but does not include regular maintenance activities performed to restore the original line, grade, or capacity of the facility.
