(a)
For any stationary source with one or more covered processes, the administering agency shall make a preliminary determination as to whether there is a significant likelihood that the use of regulated substances by a stationary source may pose a regulated substances accident risk.
(b)
(1) If the administering agency determines that there is a significant likelihood of a regulated substances accident risk pursuant to this subdivision, it shall
require the stationary source to prepare and submit an RMP, or may reclassify the covered process from program 2 to program 3, as specified in Part 68 (commencing with Section 68.1) of Subchapter C of Chapter I of Title 40 of the Code of Federal Regulations.
(2)
If the administering agency determines that there is not a significant likelihood of a regulated substances accident risk pursuant to this subdivision, it may do either of the following:
(A)
Require the preparation and submission of an RMP, but need not do so if it determines that the likelihood of a regulated substances accident risk is remote, unless otherwise required by federal law.
(B)
Reclassify a covered process from program 3 to program 2 or from program 2 to program 1, as specified in Part 68 (commencing with Section 68.1) of Subchapter C of
Chapter I of Title 40 of the Code of Federal Regulations, unless the classification of the covered process is specified in those regulations.
(3)
If the administering agency determines that an economic poison, as defined in Section 12753 of the Food and Agricultural Code, used on a farm or nursery may pose a regulated substances accident risk pursuant to this article, the administering agency shall first consult with the Department of Food and Agriculture or the county agricultural commissioner to evaluate whether the current RMP is adequate in relation to the regulated substances accident risk. This paragraph does not limit the authority of an administering agency to conduct its duties under this article, or prohibit the exercise of that authority.
(c)
The requirements of this section apply to a stationary source that is not otherwise required to submit an RMP pursuant to
Part 68 (commencing with Section 68.1) of Subchapter C of Chapter I of Title 40 of the Code of Federal Regulations.
