Current through Register 2024 Notice Reg. No. 28, July 12, 2024
The following definitions shall apply in this
						sub-chapter.
(a) "Air quality plan"
					 includes, but is not limited to, attainment, rate-of-progress, and maintenance
					 plans adopted by Districts pursuant to State requirements specified in Chapter
					 10 (commencing with section
					 40910) of Part 3 of Division 26 of
					 the Health & Safety Code (the California Clean Air Act), and federal
					 requirements specified in the Clean Air Act governing the State Implementation
					 Plan (SIP).
(b) "Certified" means
					 an interchangeable credit has been evaluated by the air pollution control
					 officer of the affected District pursuant to the requirements of this
					 sub-chapter and found to comply with all applicable District, state, and
					 federal requirements.
(c) "Credit
					 generation period" means the period of time, specified by year, in which
					 interchangeable credits are generated.
(d) "Emission reduction duration" means the
					 length of time during which the action generating the emission reduction credit
					 results in verifiable and surplus emission reductions.
(e) "Hazard Index" means the ratio of the
					 concentration of a toxic pollutant with non-cancer health effects and the
					 reference exposure level for that pollutant.
(f) "Interchangeable credit" means an
					 emission reduction credit generated from a stationary, mobile, or area source
					 that can be used, traded, or banked among programs and/or source categories as
					 specified in this regulation and in accordance with state and federal
					 law.
(g) "Reference Exposure Level"
					 means a concentration level at or below which no adverse health effects are
					 anticipated.
(h) "Registered" means
					 that an interchangeable credit has been deposited, withdrawn, or transferred
					 through the act of recording a transaction in a District's banking
					 register.
(i) "Surplus" means that
					 the reduction is not required or assumed throughout the time of the emission
					 reduction duration by any local, state or federal permit, rule, regulation,
					 law, ordinance or the most recent locally approved air quality plan, or control
					 measure implementation date. If the control efficiency or emission standard in
					 the most recent locally approved air quality plan is less stringent than the
					 control efficiency or emission standard in the applicable SIP for a specific
					 source category, then the federally approved SIP will be used for purposes of
					 determining surplus reductions.
(j)
					 "Total Hazard Index" means the sum of hazard indices for pollutants with
					 non-cancer health effects that have same or similar adverse health
					 effects.
