Summary


     The Environmental Protection Agency (EPA) final rule on clarifying the definition
 of routine maintenance under its New Source Review (NSR) process exempts industrial
 facilities from undergoing NSR if they are replacing safety, reliability, and efficiency
 rated components with new, functionally equivalent equipment and if the cost of the
 replacement components is under 20 percent of the replacement value of the process
 unit. Essentially, the rule permits owners of existing units to maintain and operate their
 units at their original design specifications without having to undergo NSR, a process
 that could require a source to meet potentially expensive pollution control requirements.
 The rule is controversial and being litigated. In December 2003, a three-judge panel of
 the D.C. Circuit Court of Appeals blocked implementation of the rule until it can make
 a final determination about the case. This paper will be updated as events warrant.

    The controversy over New Source Review (NSR) with respect to power generation
focuses on existing facilities and the conditions under which facility modifications trigger
NSR  requirements to install pollution control equipment. Retrofitting and operating
equipment designed to meet NSR requirements for existing facilities can be expensive,
and utilities have opposed recent efforts by the Environmental Protection Agency (EPA)
to enforce NSR  on existing powerplants. In particular, utilities have argued that
modifications to their facilities reflect current maintenance practices, and, therefore, are
not modifications under the meaning of the Clean Air Act (CAA).

    On  August 27, 2003, the EPA issued a final rule' on clarifying the definition of
routine maintenance under NSR. Focused on existing sources, the final rule exempts
industrial facilities from undergoing NSR for replacing safety, reliability, and efficiency
rated components with new, functionally equivalent equipment if the cost of the
