Continuous Emission Monitoring Systems Program Introduction

The program provides statewide oversight of compliance and quality assurance activities of all installed continuous opacity monitoring systems (COMS) and continuous emission monitoring systems (CEMS) required by permit or state and federal regulations.

Staff provide guidance to facilities in equipment selection and siting, testing, and quality assurance of installed COMS and CEMS. Also, staff administrating the program review and approve monitoring plans and test protocols, perform on-site observation of testing activities, and post-test review of COMS and CEMS reports.

Additional activities include obligations to EPA grant commitments such as maintaining a database of all Michigan facilities monitoring by COMS or CEMS, reviewing and tracking of submitted quarterly excess emission reports and quarterly data assessment reports.

Staff in this program are also responsible for CEMS monitoring, testing and reporting issues in the Federal Acid Rain and NOx Reduction Programs.
