The following ES&H document has been published:

This is a major revision of an existing chapter.

The SLAC Environment, Safety, and Health Manual (SLAC-I-720-0A29Z-001-R023) is being revised.

This Chapter 26, ?Stormwater?, has been revised. Stormwater flowing through industrial activity areas, such as those on the SLAC site, can carry pollutants into local water bodies if upstream sources are not properly managed.

The California State Water Resources Control Board (SWRCB) regulates stormwater runoff through a general permitting process that applies to all industrial activity sites, including SLAC. Key components of this process include the mandatory development of a stormwater pollution prevention plan (SWPPP). A SWPPP must include an inventory of potential pollution sources, best management practices (BMPs) to control pollution sources and prevent pollutants from entering the storm drain system, and a monitoring and reporting schedule to ensure the BMPs are effective. (SLAC has an SWPPP, which is being revised; critical components such as the BMPs have been included as exhibits to this chapter.)

The requirements of this chapter apply to anyone engaging in activities or using materials that may impact stormwater, the storm drain system, or the San Francisquito Creek watershed. This chapter describes all permits and permit requirements pertaining to stormwater pollution prevention and SLAC requirements to meet them. In addition to the general permit, certain activities, such as construction, or certain locations because of their importance to habitats, require specific permits. The responsibilities in this chapter for the average staff member are to ensure that best management practices (BMPs) are implemented within their areas of responsibility through job hazard analysis and mitigation (JHAM), area hazard analysis (AHA), and/or operating procedures, as appropriate. Supervisors need to ensure that employees under their supervision receive required training and resources to implement BMPs. UTR?s, CEF personnel, and some other specialized groups have other responsibilities spelled out in Section 5.1.5, ?Roles and Responsibilities.?

This document replaces the existing Chapter 26, ?Stormwater?, published in October 2000.
