|
|
| The 1987 amendments to the federal Clean Water Act (CWA) added Section 402(p), which defined storm water discharges from industrial activities and municipal systems as point sources subject to the National Pollutant Discharge Elimination System (NPDES) Permit Program, including school district operations and transportation facilities. The first phase began in 1990 and addressed discharges from Municipal Separate Storm Sewer Systems (MS4s) that serve populations greater than 100,000 people. The second phase began in 1999 and addressed discharges from MS4s that serve populations less than 100,000 and are located in urbanized areas. |
|
| As part of Phase II, the State Water Resources Control Board (SWRCB) adopted a General Permit for the Discharge of Storm Water from Small MS4s (WQ Order No. 2003-0005-DWQ) to provide permit coverage for smaller municipalities, including non-traditional Small MS4s, which are governmental facilities such as school campuses and district owned and operated building complexes. The MS4 permits require the discharger to develop and implement a Storm Water Management Plan/Program with the goal of reducing the discharge of pollutants to the maximum extent practicable (MEP) at all district owned and operated facilities including school campuses. The program areas include student and staff education and outreach; illicit discharge detection and elimination; construction and post-construction; and good housekeeping practices. |
