Continuous Emission Monitoring System (CEMS)
A continuous emission monitoring system (CEMS) is the total equipment required 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 regulations for either determining continual compliance or when standards are exceeded.
The individual subparts of the 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.
Industries such as Power, Cement, Iron & Steel, Chlor-alkali, Pharmaceuticals, Fertilizers,
Refineries, Pesticides, Distilleries, Sugar, Pulp & Paper, Textile, Tanneries, and other categories
of industries release large quantities of pollutants through effluent discharge and air pollution.
In order to regulate such emissions and discharges within safe limits, compliance monitoring needs
strengthening to ensure that industries and facilities comply with emission standards.
With ACUITY Analytics industrialization, it is becoming a need and necessity to regulate the
compliance aspects with minimal inspection of industries. Therefore, efforts need to be made
to bring discipline in the industries to exercise self-monitoring & impart confidence in their
compliance to meet notified standards; one such mechanism is to implement online emission and
effluent monitoring systems and transfer reliable data on compliance to regulatory authorities.
Online emission and effluent monitoring systems need to be installed and operated by the
developers and the industries.
