(a) The regulations adopted by the state board, on or before July 1, 1997, shall include, but need not be limited to, provisions that ensure all of the following:
(1) That emissions from portable equipment subject to the statewide registration program will not, in the aggregate, interfere with the attainment or maintenance of state or federal ambient air quality standards and the emissions from any one portable equipment engine, exclusive of background concentration, shall not cause an exceedance of any ambient air quality standard. This paragraph shall not be construed as requiring portable equipment operators to provide emission offsets for portable equipment registered under the program.
(2) (A) That, to the extent not in conflict with federal law, the registration program preserves the most stringent requirements adopted by a district which require the use of best available control technology (BACT) for each class or category of portable equipment determined appropriate by the state board, and which requirements were in effect on January 1, 1995. In determining the appropriate emission limits or emission control technology requirements for classes and categories of portable equipment, the state board may set different requirements for portable equipment that is defined by the state board as California resident portable equipment.
(B) Notwithstanding subparagraph (A) and, to the extent not in conflict with federal law, the state board may consider technical and economic feasibility in establishing emission limits or control equipment requirements for any category or class of existing California resident portable equipment, if all portable equipment in that category or class is required to be modified or replaced to meet BACT or the more stringent of a state or federal emission standard, at a date determined by the state board.
(3) That any registered portable equipment, including any turbine, used by the Department of Defense or the National Guard exclusively for military technical support or other federal emergency purposes, as specified in the regulations adopted by the state board, is not subject to any statewide or district emission control or emission limit.
(b) No emission limit or emission control requirement shall be established for any portable equipment defined by the state board as California resident portable equipment unless the state board determines that the emission limit or emission control requirement is technologically and economically feasible and is necessary to carry out the express terms of this division, including, but not limited to, Section 43013, or to attain or maintain state or federal ambient air quality standards.
(c) Prior to adopting any emission limit or emission control requirement, the state board shall consider the magnitude of the resultant air quality benefits and the potential effects of the regulation on the costs to businesses that use the portable equipment.
(d) The emission limits established for any portable equipment or class of portable equipment shall reflect the effectiveness of all control equipment installed and operated on the portable equipment or particular class of portable equipment.
(e) No emission limits other than those established by the state board for any portable equipment or class of portable equipment shall be used by a district for purposes of calculating and reporting emissions from portable equipment subject to this article.
(f) Any recordkeeping and reporting requirements prescribed by the state board for the purpose of tracking portable equipment utilization and movement shall be the minimum that is necessary to provide sufficient emission inventory data and allow adequate enforcement of the registration program.
(g) Source testing of portable equipment emissions for registration purposes shall not be required if there is no emission standard applicable to portable equipment, or if acceptable emissions data is available. For purposes of this subdivision, “acceptable emissions data” means emissions data representative of current portable equipment operations that is either reliable emissions data from the portable equipment manufacturer or a source test performed within three years prior to the date that the emissions data is requested.
