DEPARTMENT OF ENVIRONMENTAL QUALITY

DIVISION 244

OREGON FEDERAL AND STATE HAZARDOUS AIR POLLUTANT PROGRAM

General Provisions for Stationary Sources

340-244-0010

Policy and Purpose

The Environmental Quality Commission finds that certain air contaminants for which there are no ambient air quality standards may cause or contribute to an identifiable and significant increase in mortality or to an increase in serious irreversible or incapacitating reversible illness or to irreversible ecological damage, and are therefore considered to be hazardous air pollutants. It is the policy of the Commission that no person may cause, allow, or permit emissions into the ambient air of any hazardous substance in such quantity, concentration, or duration determined by the Commission to be injurious to public health or the environment. The purpose of this Division is to establish emissions limitations on sources of these air contaminants. In order to reduce the release of these hazardous air pollutants and protect public health and the environment, it is the intent of the Commission to adopt by rule within this Division the source category specific requirements that are promulgated by the EPA, and state standards to reduce the release of these hazardous air pollutants. Furthermore, it is hereby declared the policy of the Commission that the standards contained in this Division are considered minimum standards, and as technology advances, protection of public health and the environment warrants, more stringent standards may be adopted and applied.

Operating Restrictions That Apply To Tier 2 CAGMs

(1) Subject to the limitations in OAR 340-244-9030, and except as allowed in section (2), Tier 2 CAGMs may use raw materials containing chromium in glassmaking furnaces only if DEQ has established annual and daily maximum allowable chromium usage rates that will prevent the source from exceeding the chromium VI source impact levels described in paragraph (3)(b)(C) of this rule.

(2) Notwithstanding section (1) and OAR 340-244-9030(1), (3) and (4), raw materials containing chromium may be used in glassmaking furnaces for the purpose of conducting the emissions testing under sections (3) or (4). Such use must be limited to only the amounts needed to perform the testing.

Other Glassmaking HAPs

(1) If DEQ determines that ambient concentrations of a glassmaking HAP in the area of a CAGM pose an unacceptable risk to human health and that emissions from a glassmaking furnace at the CAGM are a contributing factor, then DEQ must set a limit on the CAGM’s use of the glassmaking HAP of concern, by agreement or in a permit, to reduce such risk. DEQ must consult with the Oregon Health Authority when applying this rule.
