Title: NESHAP: Reciprocating Internal Combustion Engine
Abstract: The stationary reciprocating internal combustion engine source category is listed as a major source of hazardous air pollutants (HAPs) under section 112 of the Clean Air Act (CAA). A major source is one which emits more than 10 tons/yr of one HAP or more than 25 tons/yr of a combination of 189 HAPs. The EPA will gather information on HAP emissions from internal combustion engines and determine the appropriate maximum achievable control technology (MACT) to reduce HAP emissions. The EPA will use information that has already been developed, if possible, by gathering information by working with State/local agencies, vendors, manufacturers of internal combustion engines, owners and operators of internal combustion engines, and environmentalists.

Statement of Need: Reciprocating Internal Combustion Engines is a source category listed to be regulated under Section 112 of the Clean Air Act.

Summary of the Legal Basis: Section 112 of the Clean Air Act.

Alternatives: The principal alternatives are to set standards at or beyond the "floor" level of stringency. The "floor is the minimum stringency implied by the Congressionally-given formula in Section 112 of the Clean Air Act.

Anticipated Costs and Benefits: In Section 112 of the Clean Air Act, Congress found that there is sufficient evidence of risk to warrant a broad, technology-based MACT program to reduce toxic emissions nationwide. Therefore, separate cost/benefit analyses are not conducted for individual rulemakings within the MACT program. Total annualized cost for rule is $248 million, average cost/facility $62,000 for 4600 existing sources and 20,000 new sources.

Risks: In Section 112 of the Clean Air Act, Congress found that there is sufficient evidence of risk to warrant a broad, technology-based MACT program to reduce toxic emissions nationwide.
