DATES: 1974-
ARRANGEMENT: Alphabetical by company, thereunder chronological by year

DESCRIPTION: These are annual reports containing estimates of the amount of air contaminants released into the air by process industries. The emissions inventories are required by UAC R307-155-3(1998). These inventories are from sources specifically named in existing State Implementation Plans (SIP) and the Administrative Rules resulting from these plans. The reports include stack or vent information, control equipment information, process information, fuel information, fugitive emissions information, reports on sand and gravel operations, cement plants, asphalt plants, unpaved road usage, fugitive dust, off-highway mobile sources, quarry and mining activities, vapor de-greasers, paint usage, gas processing/production, oil/natural gas production, fugitive hydrocarbon emissions/refining, and storage tanks. All forms contain the name of the company, its mailing and plant addresses, and the name and title of the contact person, as well as a breakdown of the amounts and types of pollution that is estimated to be released into the atmosphere. The emissions inventories are required to be kept as backup documents as long as the SIP is in effect.

Administrative Legal

These reports are sources for State Implementation Plans (SIPs) and provide an information base for the Division of Air Quality's Administrative Rules. The Emissions Inventories are required by UAC R307-155(1998). A twenty-three year retention is requested because 42 USC 7505a requires the SIP be retained for ten years after redesignation of a nonattainment area (an area which did not reach air quality goals) to an attainment area (an area which has reached the air quality goals). The extended retention allows the maintenance of the SIP's supporting data as long as the Administrative Rules are affected. These reports do not have a permanent retention period because the SIPs are required to be reviewed or updated which results in replacement of the existing inventory data in the plans. The SIPs are retained permanently under series 7590.
