Performance Specification 1 (PS1) provides
(1) requirements for the design, performance, and installation of a continuous opacity monitoring system (COMS) and
(2) data computation procedures for evaluating the acceptability of a COMS. It specifies activities for two groups (1) the owner or operator and (2) the opacity monitor manufacturer.
Opacity monitors help companies monitor the amount of visible emissions, smoke or opacity created during their combustion process.
