National Pollutant Discharge Elimination System (NPDES)
NPDES was created by the federal government under the Clean Water Act to reduce the amount of pollution flowing into our rivers, lakes, and oceans. This pollution damages the environment and creates a public health risk. The EPA and the California Regional Water Quality Control Board administer the program that requires the City of San Gabriel to meet standards pertaining to waste discharge from municipal stormwater and urban runoff. For more about the EPA’s program, please visit the following website.

SUSMP
The SUSMP identifies the best management practices that must be used in specific development projects. The SUSMP is developed by the County and must be approved by the California Regional Water Quality Control Board. To learn more about SUSMP please visit the California EPA site.
