The California Water Boards' Annual Performance Report - Fiscal Year 2014-15

MEASUREMENTS  - Data Last Updated on:  06-22-2016 (2:44 pm)

WHAT THE MEASURE IS SHOWING

In Fiscal Year (FY) 2014-15, the Storm Water Program inspected 16 percent of construction facilities statewide with 1,731 inspections performed at 1,454 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.

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). Inspections are the primary tool used in the NPDES Construction Storm Water Program to assess compliance with NPDES requirements. The Construction Storm Water Program is unique in that some industrial activities (e.g., construction or land disturbance) is temporary in nature. Other industrial activities tend to be more long-term (e.g., cement manufacturing and auto dismantling). As a result, it is critical that inspections of construction facilities occur during actual construction activity. Most construction sites follow a process of (1) grading and land development phase, (2) streets and utilities phase, (3) vertical construction phase, and (4) post construction phase. The type of storm water controls vary depending on the phase of construction. It is also helpful to inspect a construction site during both wet and dry weather periods to determine permit compliance. For all of these reasons, the Storm Water program considers inspection of construction facilities a high priority.

GLOSSARY

Construction Stormwater Program

Dischargers whose projects disturb 1 or more acres of soil or are part of a larger common plan of development that in total disturbs 1 or more acres, are required to obtain coverage under the General Permit for Discharges of Storm Water Associated with Construction Activity (Construction General Permit, 2009-0009-DWQ).

General Permit

An NPDES permit issued under 40 CFR 122.28 that authorizes a category of discharges 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.

Inspection (Compliance and Non Compliance)

The Regional Board or State Board may inspect the facilities of any discharger at any time pursuant to Water Code, Section 13267. Compliance activities include all activities necessary to determine if discharges are in compliance with waste discharge requirements, NPDES permits, and related enforcement orders. Compliance inspections are classified as either Level A or Level B, with Level A being more thorough.
