SUBJECT: 	September 30, 2022, Meeting with the Institute of Clean Air Companies (ICAC) on PM Monitoring and Controls for the MATS Risk and Technology Review


SUMMARY

A virtual meeting between the U.S. EPA and members of the Institute of Clean Air Companies (ICAC) was held on September 30, 2022. The purpose of the meeting was to discuss cost information related to PM Continuous Emissions Monitoring Systems (CEMS) to inform the review of the MATS Residual Risk and Technology Review (RTR).

The following cost information was provided to EPA and used in the review of the MATS RTR:
 Costs of PM CEMS
 $25,000-$30,000 for equipment
 $10,000 equipment installation
 $12,000/year to main equipment
 This cost may be able to be spread across a facility's CEMS
 Cost of PM testing
 $6,000/year-$12,000/year per source test

Attendees also provided their impressions regarding operator preferences on the frequency of testing. More specifically, the attendees indicated that, if any source was required to do quarterly stack testing, units would likely prefer to use CEMS; whereas if any source only needed annual testing, then the units would likely prefer to conduct stack testing.
