(a) The department shall establish specific numerical values for water solubility, soil adsorption coefficient (Koc), hydrolysis, aerobic and anaerobic soil metabolism, and field dissipation. The values established by the department shall be at least equal to those established by the Environmental Protection Agency. The department shall revise the numerical values when the department finds that the revision is necessary to protect the groundwater of the state. The numerical values established or revised by the department shall always be at least as stringent as the values being used by the Environmental Protection Agency at the time the values are established or revised by the department.
(b) On or before December 31, 2004, and updated at least annually thereafter, the director shall post the following information on the department’s Internet Web site for each pesticide registered for agricultural use and during years that specific numerical values are revised:
(1) A list of each active ingredient, other specified ingredient, or degradation product of an active ingredient of a pesticide for which there is a groundwater protection data gap.
(2) The Groundwater Protection List established pursuant to subdivision (d) of Section 13145.
(3) For each pesticide listed pursuant to paragraph (2) for which information is available, a list of the amount sold in California during the most recent year for which sales information is available and where and for what purpose the pesticide was used, when this information is available in the pesticide use report.
(c) The department shall determine, to the extent possible, the toxicological significance of the pesticides listed in the Groundwater Protection List.
