California Code, Health and Safety Code - HSC § 39668

(a) The state board shall, on or before January 1, 1989, prepare a written report on the availability and effectiveness of toxic air contaminant monitoring options in consultation with the Scientific Review Panel on Toxic Air Contaminants, the districts, the Department of Pesticide Regulation, and the Office of Environmental Health Hazard Assessment. In preparing the report, the state board shall conduct at least one public workshop. The report shall include, but not be limited to, all of the following:

(b) Based on the findings in the report prepared pursuant to subdivision (a), the state board shall develop, by July 1, 1989, in conjunction with the districts, guidelines for establishing supplemental toxic air contaminant monitoring networks to be implemented by the districts. The board shall develop the guidelines only to the extent that it determines, pursuant to paragraph (2) of subdivision (a), that establishing additional monitoring capacity is appropriate and feasible.

(c) The guidelines established pursuant to subdivision (b) shall include a priority list for establishing and implementing the supplemental toxic air contaminant monitoring networks. The state board shall give priority to that supplemental monitoring capacity it determines to be most needed to identify and control toxic air contaminants. The state board shall allocate to districts, in the priority order included in the guidelines, state funds provided in subdivision (b) of Section 3 of the act adding this section and in subsequent Budget Acts for establishing and implementing the supplemental toxic air contaminant monitoring networks. The state board shall allocate state funds to the districts, upon appropriation by the Legislature, on a 50 percent matching basis, and shall not provide state funds for the supplemental toxic air contaminant monitoring program established by Section 40715 to any district in excess of district funds allocated by the district in establishing and implementing the supplemental monitoring networks created pursuant to Section 40715.

(d) The state board shall request in its annual budget sufficient state funds, in addition to those provided in subdivision (b) of Section 3 of the act adding this section, to match, on a 50 percent basis, those district funds allocated by the districts for establishing and implementing the supplemental monitoring program specified in the guidelines adopted pursuant to subdivision (b).
