NESHAP National emissions

Once a substance is designated by EPA as a ha2ardous air pollutant (HAP), EPA has to promulgate a NESHAP (National Emission Standard for Ha2ardous Air Pollutants), designed to protect pubHc health with an ample margin of safety.

Since 1990, several new or revised U.S. environmental regulations, which significantly affect refinery wastewater treatment systems, have been promulgated. The most important ones include the revised Toxicity Characteristics (TC) rule, the Primary Sludge rule, and the Benzene NESHAP (National Emissions Standards for Hazardous Air Pollutants) rule. These regulations and their impacts on refinery wastewater facilities are briefly discussed below.

The statutory requirements addressed by each option are identified in the seventh column of Table X titled Statutory program. The specified compliance dates for each statutory program are also shown in the table, as are the implementation times for each option. Since the maximum achievable control technology (MACT) requirements have not yet been specified by EPA, projects directed toward those requirements have not yet been undertaken. That being the case, the implementation times identified indicate that options 5, 8, and 9 may have difficulty achieving timely compliance with these regulatory requirements. To proceed with the analysis, requirements that might be imposed under MACT were hypothesized to specify the performance characteristics of the associated pollution prevention options. It should be noted that only those options related with compliance with the Benzene Waste NESHAP (National Emissions Standard for...
