Water Quality Laws
There are multiple laws on federal, state and local levels that regulate storm water pollution and discharges.
Federal Clean Water Act
, passed in 1977, is the basis for our water quality laws today.
California’s primary law granting the authority to implement storm water regulations is the
Porter-Cologne Water Quality Control Act
. This law allowed our California Environmental Protection Agency to create the State Water Resources Control Board and the nine Regional Water Quality Control Boards.
San Diego Regional Water Quality Control Board
The San Diego Regional Water Quality Control Board adopted the Comprehensive Water Quality Plan for the San Diego Basin (
) in 1994.
The San Diego Regional Water Quality Control Board issued new regulations concerning storm water discharges in December of 2009, affecting all industrial and commercial businesses, construction sites, residents and municipal agencies. These new
Municipal Storm Water Discharge Requirements
have become the basis for the City of Laguna Niguel’s local ordinances.
Construction activity resulting in a land disturbance of one acre or more, or less than one acre but part of a larger common plan of development or sale must obtain the
Construction Activities Storm Water General Permit

Construction activity does not include routine maintenance such as, maintenance of original line and grade, hydraulic capacity, or original purpose of the facility.
