Upcoming EPA decisions on HAP residual risks
Section 112 of the 1990 Clean Air Act Amendments requires EPA to regulate hazardous air pollutants (HAPs). Section 112(d) requires that maximum achievable control technology (MACT) be applied to HAP source categories on a specified schedule. EPA has officially listed about 175 source categories and is evaluating a number of others. Eight years after each MACT standard is promulgated, section 112(f) requires that the risks that remain after application of MACT (i.e., the residual risks) be assessed and additional control required to provide an ample margin of safety protect public health or to prevent an adverse environmental effect. On April 22, 1998, EPA released a draft Residual Risk Report to Congress as required by section 112(f)(1) of the 1990 Amendments. In this draft report, EPA described methods for assessing HAP risks, the significance of HAP risks and actual health effects to the extent known, and EPA's planned residual risk strategy. EPA solicited public comment and a final report is due to Congress in 1999. While the first residual risk regulation will likely not be promulgated by EPA until 2001 or 2002, regulatory development is likely to begin in 1999, soon after the report to Congress is finalized. The draft Residual Risk Report describes the residual risk decision process planned by EPA and this is unlikely to significantly change. The decision process could have a lasting effect on many HAP sources and industries. A number of sources and industries emitting HAPs will be significantly affected by EPA's planned residual risk regulatory program. This paper will identify the types of HAPs and HAP sources most likely to be affected and recommend actions and timing for meeting the likely regulatory requirements.
