CEMS....
A continuous emission monitoring system (CEMS) is the total equipment necessary for the determination of a gas or particulate matter concentration or emission rate using pollutant analyzer measurements and a conversion equation, graph, or computer program to produce results in units of the applicable emission limitation or standard.
A continuous emission monitoring system (CEMS) is the total equipment necessary for the determination of a gas or particulate matter concentration or emission rate using pollutant analyzer measurements and a conversion equation, graph, or computer program to produce results in units of the applicable emission limitation or standard.
CEMS are required under some of the Clean Air Regulations 1974
(revised 2014) issued by Department of Environment (DOE) regulations for either
continual compliance determinations or determination of exceedances of the
standards. The individual subparts of the DOE rules specify the reference
methods that are used to substantiate the accuracy and precision of the CEMS.
Performance Specifications are used for evaluating the acceptability of the
CEMS at the time of or soon after installation and whenever specified in the
regulations.
Quality assurance procedures are used to evaluate the
effectiveness of quality control (QC) and quality assurance (QA) procedures and
the quality of data produced by any CEMS that is used for determining
compliance with the emission standards on a continuous basis as specified in
the applicable regulation
