The owner or operator of any facility that intends to install a CEMS or COMS shall notify the commissioner at least 60 days prior to installation of the monitoring system. The notification shall include plans and drawings of the proposed system which show the configuration of the monitoring system including any monitor bypass routes.
A CEMS or COMS shall be installed in a location that provides data which is representative of emissions and which is in accordance with the requirements listed in the appropriate performance specifications in Code of Federal Regulations, title 40, part 60, appendix B. If the monitoring system is required by the Acid Rain Program, Title IV of the Clean Air Act, it must be installed according to the installation requirements of Code of Federal Regulations, title 40, part 75.
When the emissions from two or more emission units are subject to the same emission limit and are combined before being released to the atmosphere, the owner or operator may install a CEMS or COMS on each emission unit or may elect to monitor the combined emission stream of the emission units. When two or more emission units required to be monitored with a CEMS or COMS are not subject to the same emission limit, a separate CEMS or COMS shall be installed on each emission unit, except in cases where an extractive CEMS or COMS is time-shared between the emission units. When the effluent from one emission unit can be released to the atmosphere through more than one point, the owner or operator shall install a CEMS or COMS on each separate emission stream unless the installation of fewer systems is approved in writing by the commissioner.
