WHAT THE MEASURE IS SHOWING
In Fiscal Year (FY) 2017-18, the Storm Water Program inspected 14 percent of industrial storm water facilities, with 1,938 inspections performed at 1,834 facilities statewide. Industrial storm water facilities are unlikely to change significantly over time, so the frequency of inspections necessary to verify compliance may be lower than the frequency necessary for construction storm water facilities. For compliance purposes, some facilities are inspected more than once a year, which is why the total number of inspections is greater than the total number of facilities inspected. As a percentage of facilities inspected, the FY 17-18 inspection rate is similar to the inspection rate reported over the last several FYs statewide.
WHY THIS MEASURE IS IMPORTANT
Inspections are a primary tool used in determining and documenting compliance with National Pollutant Discharge Elimination System (NPDES) permits and waste discharge requirements (WDR). The NPDES Storm Water Program uses inspection to assess compliance with NPDES requirements. The General Industrial Permit requires that an annual report be submitted each July 1st, which is used in conjunction with site inspections to verify facilities are in compliance with permit requirements.

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.
- 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 (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.
- Facilities
- Include any construction facility enrolled under the storm water construction program that was active at least one day during the fiscal year.
- Inspection
- Inspections conducted by Regional or State Water Board staff, or US EPA. Inspection types include A Type and B Type Compliance, Complaint, Enforcement Follow-up, Inspection from Vehicle, No-Exposure Certification (NEC), Notice of Termination (NOT), NonFiler/Notice of Non-Applicability (NONA), and Non-compliance Follow-up.
