WHAT THE MEASURE IS SHOWING

WHY THIS MEASURE IS IMPORTANT

The Construction Storm Water Program is unique in that some industrial activities (e.g., construction or land disturbance) is temporary in nature. The general permit requires visual monitoring at all sites, and effluent water quality at all Risk Level 2 and 3 sites. The general permit also requires receiving water monitoring at some Risk Level 3 sites. All sites are required to submit annual reports, which contain various types of information, depending on the site characteristics and events. Annual reports must be submitted by projects that are enrolled under 2009-0009-DWQ for more than one continuous three month period. The Annual Reports will be submitted electronically in SMARTS. Annual reports are for July 1 through June 30, and are due to the Water Boards on September 1 of each year. For projects that are active for more than one continuous three month period, and that complete construction prior to September 1, an annual report is still be required to be submitted electronically in SMARTS prior to the enrollee submitting a notice

GLOSSARY

Construction Storm Water 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).

Annual Report

All dischargers must prepare and electronically submit an annual report no later than September 1 of each year using the Storm water Multi-Application Reporting and Tracking System (SMARTS). The Annual Report must include a summary and evaluation of all sampling and analysis results, original laboratory reports, chain of custody forms, a summary of all corrective actions taken during the compliance year, and identification of any compliance activities or corrective actions that were not implemented.).

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.
