b. The emissions trading rules and regulations shall be designed so that emissions reductions shall be realized earlier or at a more accelerated rate than would otherwise be achieved in accordance with applicable air quality mandates, and so that compliance with air quality mandates can be achieved with greater flexibility or at lower cost. The rules and regulations shall establish criteria for the generation and use of emissions reduction credits, including the use of emissions reduction credits in lieu of granting exemptions or waivers from compliance with emissions reduction requirements, and shall require that 10% of the emissions reduction credits gained shall be permanently retired for the public benefit when a trade occurs. The rules and regulations may include, but need not be limited to, provisions designating the pollutants to be involved in the program, designating the persons who may participate in the program, establishing emissions limitations and methods for projecting and verifying emissions, and establishing enforcement mechanisms, including emissions tracking, periodic program audits, and penalties. For any emissions trading program adopted for the purpose of making progress toward attaining the National Ambient Air Quality Standard (NAAQS) for ozone, the department may allow reductions of volatile organic compounds (VOCs) to be substituted for required reductions of oxides of nitrogen (NOx) or reductions of oxides of nitrogen (NOx) to be substituted for required reductions of volatile organic compounds (VOCs). Any such substitution shall occur at a ratio established by the department by rule or regulation adopted pursuant to the "Administrative Procedure Act," P.L. 1968, c.410 (C.52:14B-1 et seq.), which shall be developed in recognition of the role of each pollutant in the formation of ground level ozone.
