The draft CAM proposal specifies a lower size cut-off for process units based on potential emissions levels below which no additional monitoring would be required. The emission units to be covered by the draft CAM rule amount to about 60 percent of those fitted with control equipment and about 20 percent of all other emission units. Altogether, the CAM requirements will require monitoring for over 97 percent of the total emissions from all units at sources receiving Title V operating permits. EPA received extensive public comments from stakeholders on its initial draft of the compliance assurance monitoring rule issued in September 1995. EPA has addressed these concerns in today's action.
Size cutoffs focus requirements on significant units.
Requirements of the CAM plan have been streamlined so that the CAM plan can be included in the Title V permit. The Title V permit would include the monitoring approach, data availability requirements, indicator ranges, corrective action obligations and quality improvement plan requirements. EPA will accept public comment on the second draft of the compliance assurance monitoring rule for 60 days after publication of the notice of availability in the Federal Register. EPA will carefully consider all public comments before issuing the final rule in July 1997.
