WHAT THE MEASURE IS SHOWING
WHY THIS MEASURE IS IMPORTANT
The operators of industrial storm water facilities are required submit an annual report (called Self-Monitoring Reports or SMRs) to the Executive Officer of the Regional Water Board responsible for the area in which the facility is located and to the local agency (if requested), by July 1 of each year. SMRs contain the information required to assess the quality of a regulated facility's discharge and the facility's compliance with its permit. SMRs typically include both the data required by the permit as well as any additional date the permitted has collected, consistent with permit requirements. SMRs often include an assessment of discharge conditions, analysis performed by a certified laboratory, and field measurements (such as pH and stream flow). Regional Water Board staff review reports to determine if the reports are complete, and if the reported values are within the permitted limits. In 2010, the Water Boards transitioned to tracking both paper and electronic form monitoring reports due, received, and reviewed in the CIWQS database. This card shows the progress towards tracking monitoring and reviewing reports from all permitted facilities.

GLOSSARY
- Industrial Storm Water Program
- 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.
- Storm Water
- "Storm water" means storm water runoff, snow melt runoff, and storm water surface runoff and drainage. It excludes infiltration and runoff from agricultural land. "Storm Water Associated with Industrial Activity" means the discharge from any conveyance which is used for collecting and conveying storm water and which is directly related to manufacturing, processing, or raw materials storage areas at an industrial plant.
- National Pollutant Discharge Elimination System (NPDES)
- The NPDES permit program (Section 402 of the Clean Water Act) 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.
