MENDOCINO COUNTY AIR QUALITY MANAGEMENT DISTRICT

RULE 5-110 - PURPOSE

On November 12, 1987, pursuant to Section 39662 of the Health and Safety Code, the Air Resources Board (ARB) identified ethylene oxide as a toxic air contaminant. In so identifying ethylene oxide, the Air Resources Board determined that there is not sufficient available scientific evidence to support identification of a threshold exposure level below which no significant adverse health effects are anticipated (see California Code of Regulations Section 93000). This airborne toxic control measure will reduce ethylene oxide emission from sterilizers and aerators and cancer incidence to the lowest level achievable through application of best available control technology at operations subject to this measure.
