(a) In addition to complying with the requirements of this chapter, a permit system established by a district pursuant to Section 42300 shall ensure that any agricultural source that is required to obtain a permit pursuant to Title I (42 U.S.C. Sec. 7401 et seq.) or Title V (42 U.S.C. Sec. 7661 et seq.) of the federal Clean Air Act is required by district regulation to obtain a permit in a manner that is consistent with the federal requirements.
(b) Except as provided in subdivision (c), a district shall require an agricultural source of air pollution to obtain a permit unless it makes all of the following findings in a public hearing:
(1) The source is subject to a permit requirement pursuant to Section 40724.6.
(2) A permit is not necessary to impose or enforce reductions of emissions of air pollutants that the district shows cause or contribute to the violation of a state or federal ambient air quality standard.
(3) The requirement for the source or category of sources to obtain a permit would impose a burden on those sources that is significantly more burdensome than permits required for other similar sources of air pollution.
(c) Prior to requiring a permit for an agricultural source of air pollution with actual emissions that are less than one-half of any applicable emissions threshold for a major source in the district for any air contaminant, but excluding fugitive dust, a district shall, in a public hearing, make all of the following findings:
(1) The source is not subject to a permit requirement pursuant to Section 40724.6.
(2) A permit is necessary to impose or enforce reductions of emissions of air pollutants that the district shows cause or contribute to a violation of a state or federal ambient air quality standard.
(3) The requirement for a source or category of sources to obtain a permit would not impose a burden on those sources that is significantly more burdensome than permits required for other similar sources of air pollution.
