WHAT THE MEASURE IS SHOWING
As of the end of Fiscal Year (FY) 2014-15, 8,808 facilities were regulated under the Industrial Storm Water Program. In FY 14-15, the program added 701 new or updated enrollees and terminated the enrollment of 770 facilities. The regions with significant industrial activity tend to have the greatest number of facilities enrolled under the Industrial Storm Water Program.
WHY THIS MEASURE IS IMPORTANT
The Industrial Storm Water Program regulates a large number of facilities statewide. Although the program's activity is not as temporary in nature as the Construction Storm Water Program, the industrial program requires frequent verification that facilities (both new and previously enrolled) are in compliance with NPDES storm water regulations. Non-municipal, or industrial sources, often generate wastewater that is discharged to surface waters. The types of wastewater generated at a facility depend on the specific activities undertaken and may include manufacturing or process wastewaters, cooling waters, sanitary wastewater, and storm water runoff. The Industrial Storm Water Program is highly dynamic and many new applications are received each year. Processing new applications and rescinding existing permits requires a significant amount of time and resources, and is considered a good indicator of overall program performance.
TECHNICAL CONSIDERATIONS
Data Source: SMARTS July 1, 2015 to June 30, 2016.
Unit of Measure: Number of enrolled facilities and terminated facilities under the program during FY 15-16.
Data Definitions: Facilities enrolled under a general industrial storm water permit.
Discharges associated with 10 broad categories of industrial activities are regulated under the Industrial Storm Water General Permit Order 2014-0057-DWQ (General Industrial Permit), which is an NPDES permit.
General Permit
An NPDES permit issued under 40 CFR 122.28 that authorizes a category of discharges under the Clean Water Act (CWA) within a geographical area. A general permit is not specifically tailored for an individual discharger.
National Pollutant Discharge Elimination System (NPDES)
The NPDES permit program (CWA Section 402) controls water pollution by regulating point sources that discharge pollutants into waters of the United States. Point sources are discrete conveyances such as pipes or man-made ditches. Individual homes that are connected to a municipal system, use a septic system, or do not have a surface discharge do not need an NPDES permit; however, industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters. US EPA has approved the Water Board's program to issue NPDES permits.
