Title 42 › Chapter CHAPTER 85— - AIR POLLUTION PREVENTION AND CONTROL › Subchapter SUBCHAPTER I— - PROGRAMS AND ACTIVITIES › Part Part D— - Plan Requirements for Nonattainment Areas › Subpart subpart 1— - nonattainment areas in general › § 7503
Permits to build or run new or changed big pollution sources can only be issued when the permit agency finds several things are true. The agency must follow EPA rules for measuring baseline emissions and must make sure enough emission reductions (offsets) are obtained so total allowable emissions in the region will be lower than before the permit application and will count toward “reasonable further progress.” In a special zone chosen for economic development, a new big source must not make emissions go above the cap set for new or changed major sources. The new or changed source must meet the lowest achievable emission rate. The owner must show all major sources they control in the State have limits and are following them or are on a schedule to do so. The EPA must not have decided the area’s air quality plan is not being properly carried out. The permit agency must also show that other sites, sizes, processes, or pollution controls were checked and that the benefits of this project clearly outweigh its environmental and social costs. A growth allowance written into older state plans (as they read before November 15, 1990) cannot be used in any area that got a notice saying the plan was substantially inadequate under the earlier law. Offsets to cover increased pollution must come from the same nonattainment area unless the State allows using reductions from another nonattainment area that has the same or worse classification and that area’s emissions help cause the violation. Those reductions must be enforceable and in effect by the time the source starts, and must equal or exceed the new emissions. Emission reductions already required by this law cannot be counted, but voluntary reductions that meet the rules may be. States must send control-technology details from these permits to EPA so others can see them. For existing major sources that test rocket engines or motors (and were allowed to test on November 15, 1990), States may let them use alternative or innovative offsets if the source tried all reasonable offset options, got a written federal finding that the testing is needed for national security, and agrees to other offset measures or pays a fee up to 1.5 times the area’s average cost of control measures over the previous 3 years; the fees must be used to get the most emissions reductions possible.
