. The state board shall establish airborne toxic control
measures for toxic air contaminants in accordance with all of the
following:
(a) If a substance is identified as a toxic air contaminant
pursuant to Article 3 (commencing with Section 39660), the airborne
toxic control measure applicable to the toxic air contaminant shall
be adopted following the procedures and meeting the requirements of
Article 4 (commencing with Section 39665).
(b) If a substance is designated as a toxic air contaminant
because it is listed as a hazardous air pollutant pursuant to
subsection (b) of Section 112 of the federal act (42 U.S.C. Sec. 7412
(b)), the state board shall establish the airborne toxic control
measure applicable to the substance as follows:
(1) If an emission standard applicable to the hazardous air
pollutant has been adopted by the Environmental Protection Agency
pursuant to Section 112 of the federal act (42 U.S.C. Sec. 7412),
except as provided in paragraphs (2), (3), and (4), that emission
standard adopted pursuant to Section 112 of the federal act (42
U.S.C. Sec. 7412) for the hazardous air pollutant is also the
airborne toxic control measure for the toxic air contaminant. The
state board shall implement the relevant emission standard and it
shall be the airborne toxic control measure for purposes of this
chapter. The implementation of the emission standard is not subject
to Chapter 3.5 (commencing with Section 11340) of Part 1 of Division
3 of Title 2 of the Government Code or Article 4 (commencing with
Section 39665).
(2) If an emission standard applicable to the hazardous air
pollutant has been adopted by the Environmental Protection Agency
pursuant to Section 112 of the federal act (42 U.S.C. Sec. 7412) and
the state board finds that the emission standard does not achieve the
purposes set forth in subdivision (b) or (c), as applicable, of
Section 39666, the state board shall adopt an airborne toxic control
measure for the toxic air contaminant that it finds will achieve
those purposes. The state board shall, when it adopts an airborne
toxic control measure pursuant to this paragraph, follow the
procedures and meet the requirements of Article 4 (commencing with
Section 39665).
(3) If the state board implements an airborne toxic control
measure applicable to the substance pursuant to paragraph (1) and
later finds that the purposes set forth in subdivision (b) or (c), as
applicable, of Section 39666 are not achieved by the airborne toxic
control measure, the state board may revise the airborne toxic
control measure to achieve those purposes. The state board shall,
when it revises an airborne toxic control measure pursuant to this
paragraph, follow the procedures and meet the requirements of Article
4 (commencing with Section 39665). The state board may revise an
airborne toxic control measure pursuant to this paragraph only if it
first finds that the reduction in risk to the public health that will
be achieved by the revision justifies the burden that will be
imposed on persons who are in compliance with the airborne toxic
control measure previously implemented pursuant to paragraph (1).
(4) If an emission standard applicable to the hazardous air
pollutant has not been adopted by the Environmental Protection Agency
pursuant to Section 112 of the federal act (42 U.S.C. Sec. 7412),
the state board may adopt an airborne toxic control measure
applicable to the toxic air contaminant pursuant to Article 4
(commencing with Section 39665).
