Regulatory Impact Analysis Of The Proposed Reciprocating Internal Combustion Engines NESHAP, Final Report.
This report summarizes the benefits, costs, and economic impacts with the National Emissions Standards for Hazardous Air Pollutants (NESHAP) for the Reciprocating Internal Combustion Engines (RICE) source category. This source category includes spark ignition engines that operate generally with natural gas and compression ignition engines that operate with diesel fuel, and can be classified as two-stroke, or four-stroke engines. They are also classified by the richness of the fuel mix: rich burn or lean burn. RICE units are typically used along natural gas pipelines to provide adequate pressure to transmit fuel through the pipeline. Others are also used to provide power in a remote area of an operation in industries such as health services, energy generation, oil and gas extraction, and quarrying of nonmetalic minerals.
In the 5th year after implementation, the proposed NESHAP for RICE will impact existing and new engine and is expected to reduce HAP emissions by 5,000 tons per year, 234,000 tons of carbon monoxide (CO) per year, 167,900 tons of nitrogen oxides (NOx) per year, and 3,700 tons of particulate matter (PM10) per year. The total social cost of rule is approximately $255 million (1998$). This cost is spread across more than 25 different industries, which results in small economic impacts with minimal changes in prices and production levels in most affected industries. Benefits of the HAP reductions include reduced respiratory illnesses and reduced incidence of cancer, however, we are unable to quantify these effects. Benefits from NOx and PM reductions include fewer fatalities, and reduced incidence of chronic bronchitis, asthma, and other respiratory illnesses, which are valued at approximately $280 million per year.
The methodology and results of the economic impact part of this analysis differ from those in the EIA of the proposed rule dated July 2000 (see A.2000.41).
