Consolidated Federal Air Rule (CAR) for Synthetic Organic Chemical Manufacturing Industry

On this page:

Rule Summary

The Consolidated Federal Air Rule (CAR) is a pilot rulemaking originating from President Clinton's March 16, 1995 initiative to reinvent environmental regulations. This rule consolidates major portions of the following new source performance standards (NSPS) and national emission standards for hazardous air pollutants (NESHAP) applicable to storage vessels, process vents, transfer operations, and equipment leaks within the SOCMI: 40 CFR part 60, subparts A, Ka, Kb, VV, DDD, III, NNN, and RRR; 40 CFR part 61, subparts A, V, Y, and BB; and 40 CFR part 63, subparts A, F, G, and H. The rule pulls together applicable Federal SOCMI rules into one integrated set of rules in order to simplify, clarify, and improve implementation of the existing rules with which source owners or operators must comply. The consolidated rule is an optional compliance alternative for SOCMI sources; sources may simply continue to comply with existing applicable rules or choose to comply with the consolidated rule. The effect of this consolidation will be to improve understandability, reduce burden, clarify requirements, and improve implementation and compliance.
