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 › § 7509
If the EPA finds a state failed to send in required clean-air plans for an area that does not meet air standards, sent plans that were missing required parts, sent plans that were rejected, or is not carrying out an approved plan, the EPA can use penalties. One penalty is to stop federal approval of highway projects and grants for that area. The ban does not apply to projects that fix safety problems (if the Transportation Secretary agrees, based on state accident or other data). The ban still allows eight kinds of transportation projects that improve air quality, such as public transit capital programs, bus or high-occupancy vehicle lanes, employer trip-reduction planning, traffic-flow improvements like ramp metering, park-and-ride lots, downtown vehicle-use limits or pricing, congestion management systems, and other similar programs that do not promote single-occupant car use. The EPA can also require that new or changed pollution sources get emission offsets at a ratio of at least 2 to 1. After the area's deadline to meet the air standard, the EPA must decide within 6 months whether the area actually met it and must publish a notice naming areas that failed. Within 1 year after that notice, the state must submit a revised plan that meets the usual planning rules and includes any extra measures the EPA reasonably requires. Those extra measures must include all steps that are feasible given technology, costs, and other health or environmental effects. The time allowed to meet the standard under the revised plan starts from the date of the EPA’s notice of failure.
