(415 ILCS 5/9.8)
    Sec. 9.8. Emissions reductions market system.
    (a) The General Assembly finds:
        (1) That achieving compliance with the ozone attainment provisions of federal Clean Air
    
Act Amendments (CAAA) of 1990 calls for innovative and cost-effective implementation strategies.
        (2) That economic incentives and market-based approaches can be used to achieve clean
    
air compliance in an innovative and cost-effective manner.
        (3) That development and operation of an emissions market system should significantly
    
lessen the economic impacts associated with implementation of the federal Clean Air Act Amendments of 1990 and still achieve the desired air quality for the area.
    (b) The Agency shall design an emissions market system that will assist the State in meeting applicable post-1996 provisions under the CAAA of 1990, provide maximum flexibility for designated sources that reduce emissions, and that takes into account the findings of the national ozone transport assessment, existing air quality conditions, and resultant emissions levels necessary to achieve or maintain attainment.
    (c) The Agency may develop proposed rules for a market-based emissions reduction, banking, and trading system that will enable stationary sources to implement cost-effective, compliance options. In developing such a market system, the Agency may take into consideration a suitable ozone control season and related reconciliation period, seasonal allotments of actual emissions and adjustments thereto, phased participation by size of source, suitable emissions and compliance monitoring provisions, an annual allotment set-aside for market assurance, and suitable means for the market system to be provided for in an appropriate State implementation plan. The proposal shall be filed with the Board and shall be subject to the rulemaking provisions of Sections 27 and 28 of this Act. The rules adopted by the Board shall include provisions that:
        (1) Assure that compliance with the required emissions reductions under the market
    
system shall be, at a minimum, as cost-effective as the traditional regulatory control requirements in the State of Illinois.
        (2) Assure that emissions reductions under the market system will not be mandated unless
    
it is necessary for the attainment and maintenance of the National Ambient Air Quality Standard for ozone in the Chicago nonattainment area, as required of this State by applicable federal law or regulation.
        (3) Assure that sources subject to the program will not be required to reduce emissions
    
to an extent that exceeds their proportionate share of the total emission reductions required of all emission sources, including mobile and area sources, to attain and maintain the National Ambient Air Quality Standard for ozone in the Chicago nonattainment area.
        (4) Assure that credit is given or exclusion is granted for those emission units which
    
have reduced emissions, either voluntarily or through the application of maximum available control technology or national emissions standards for hazardous air pollutants, such that those reductions would be counted as if they had occurred after the initiation of the program.
        (5) Assure that unusual or abnormal operational patterns can be accounted for in the
    
determination of any source's baseline from which reductions would be made.
        (6) Assure that relative economic impact and technical feasibility of emissions
    
reductions under the banking and trading program, as compared to other alternatives, is considered.
        (7) Assure that the feasibility of measuring and quantifying emissions is considered in
    
developing and adopting the banking and trading program.
    (d) Notwithstanding the other provisions of this Act, any source or other authorized person that participates in an emissions market system shall be eligible to exchange allotment trading units with other sources provided that established rules are followed.
    (e) There is hereby created within the State Treasury an interest-bearing special fund to be known as the Alternative Compliance Market Account Fund, which shall be used and administered by the Agency for the following public purposes:
        (1) To accept and retain funds from persons who purchase allotment trading units from
    
the Agency pursuant to regulatory provisions and payments of interest and principal.
        (2) To purchase services, equipment, or commodities that help generate emissions
    
reductions in or around the ozone nonattainment area in Northeastern Illinois.
