This series document the Silicon Valley Toxic Coalition's (SVTC) role in the drafting and implementation of the Model Toxics Storage Ordinance for Santa Clara County. This ordinance was approved by the county Intergovernmental Council in May of 1983, and had been implemented in some form by fifteen municipalities in the region by 1984. This Santa Clara County Ordinances served as the blueprint for a statewide groundwater contamination legislation under State Assembly Bill AB 1362, which the state legislature adopted in the fall 1983. Ted Smith and other SVTC members led the drafting of the model ordinance and frequently participated in or spoke out at city hearings about its implementation. One controversial facet was a "right-to-know" provision requiring companies to disclose the location and contents of all potentially hazardous chemicals stored on their premises. An interrelated debate, well represented in this series, focused on the number of chemicals that should fall under the scope of the ordinance. The debate concerned whether the ordinance would apply to the full spectrum of chemicals listed as hazardous by the California Occupational Health and Safety Administration (CAL/OSHA). Between the years 1982-1983, the SVTC lobbied for similar chemical storage regulations at the state level in the form of California Assembly Bill 1362 (1985).
