2. BACKGROUND
On July 23, 2021, the Los Angeles Regional Water Quality Control Board (Regional
Board) adopted a Regional Municipal Separate Storm Sewer (MS4) NPDES Permit for
the Los Angeles Region (2021 Regional Stormwater Permit). The 2021 Regional
Stormwater Permit includes co-permittees consisting of the 10 incorporated Cities in
Ventura County, and the Watershed Protection District along with the 85 incorporated
Cities, County, and Flood Control District in Los Angeles County.
As an operator of the municipal separate storm sewer system (MS4), the City is subject
to regulatory requirements pursuant to the 2021 Regional NPDES Municipal Stormwater
Permit, Order No. R4-2021-0105 (Regional MS4 Permit). The Regional MS4 Permit
requires that the City perform non-stormwater outfall-based screening for all major outfalls
that discharge to Waters of the United States (WOTUS) and perform a source
investigation on all major outfalls determined to have a significant discharge.
