06- 096 C.M.R. ch. 100, § 74 - Intermittent Control System (ICS)
"Intermittent Control System" means a dispersion technique which varies the rate at which pollutants are emitted into the atmosphere according to meteorological conditions and/or ambient concentrations of the pollutant, in order to prevent ground-level concentrations in excess of applicable ambient air quality standards. Such a dispersion technique is an ICS whether used alone, used with other dispersion techniques, or used as a supplement to continuous emission control (i. e. , used as a supplemental control system).
