GLIN==> Great Lakes Toxic Air Emissions Inventory - New Release

For immediate release

New Great Lakes Regional Air Toxic Emissions Inventory released

Ann Arbor, Mich. -- An updated toxic air emissions inventory -– a key environmental management tool -has been released by the Great Lakes Commission.

The newest Great Lakes Regional Air Toxic Emissions Inventory is part of an effort to measure the toxic air emissions that affect the air and water quality and the communities of the Great Lakes basin. Funded by the U.S. Environmental Protection Agency, it lists emissions by type, quantity and source.

"This inventory is the single best compilation of emissions data for the Great Lakes basin," said Nathaniel Robinson, chairman of the Great Lakes Commission, which manages the project. "It lays the groundwork for air emissions research and will help guide policymaking efforts as well."

The updated inventory identifies 82 individual toxic air pollutants, emitted from 672 types of sources and generated by 1,532 different processes. Based on 1998 data collected by the eight Great Lakes states and the province of Ontario, it is the latest step in the Commission’s Regional Air Pollution Inventory Development System (RAPIDS) project, begun in 1989.

Sources fall into three broad categories:

Point sources are a single, identifiable location such as a smokestack

Area sources are generally too small and numerous to be individually assessed; they include gas stations, dry cleaners and consumer products

Mobile sources are from moving vehicles such as automobiles, boats and aircraft

The inventory project strengthens environmental decisionmaking capabilities in the basin by promoting consistency in data collection and analysis across jurisdictions, and the establishment of standard procedures and protocols. It includes development of an automated emission estimation and inventory system and demonstrates the value of the Internet as a means of exchanging environmental data.

One of the main challenges in compiling the inventory was maintaining consistency from one jurisdiction to the next, given differences in data breadth, quality and availability. As a result, the inventory should not be used to compare emissions from one state or province to another but rather to demonstrate the potential of a comprehensive inventory as a decision support tool.

The project team is now compiling an inventory of 1999 data, which will include an enhanced mercury inventory. It also designing a searchable online database, known as a datamart, which is due for release next year.
