Section 40914 Of Chapter 10. District Plans To Attain State Ambient Air Quality Standards From California Health And Safety Code >> Division 26. >> Part 3. >> Chapter 10.
40914
. (a) Each district plan shall be designed to achieve a
reduction in districtwide emissions of 5 percent or more per year for
each nonattainment pollutant or its precursors, averaged every
consecutive three-year period, unless an alternative measure of
progress is approved pursuant to Section 39607.
(b) A district may use an alternative emission reduction strategy
which achieves less than an average of 5 percent per year reduction
in districtwide emissions if the district demonstrates to the state
board, and the state board concurs in, either of the following:
(1) That the alternative emission reduction strategy is equal to
or more effective than districtwide emission reductions in improving
air quality.
(2) That despite the inclusion of every feasible measure in the
plan, and an expeditious adoption schedule, the district is unable to
achieve at least a 5-percent annual reduction in districtwide
emissions.
(c) For purposes of this section and Section 41503.1, for each
district that is designated nonattainment for a state ambient air
quality standard but is designated attainment for the federal air
quality standard for the same pollutant, reductions in emissions
shall be calculated with respect to the actual level of emissions
that exist in each district during 1990, as determined by the state
board. All reductions in emissions occurring after December 31, 1990,
including, but not limited to, reductions in emissions resulting
from measures adopted prior to December 31, 1990, shall be included
in this calculation. For each district that is designated
nonattainment for both state and federal ambient air quality
standards for a single pollutant, reductions in emissions shall be
calculated with respect to the actual level of emissions that exist
in each district during the baseline year used in the state
implementation plan required by the federal Clean Air Act. All
reductions in emissions occurring after December 31 of the baseline
year, including, but not necessarily limited to, reductions in
emissions resulting from measures adopted prior to December 31 of the
baseline year, shall be included in this calculation.
