Inventory of Great Lakes toxic air emissions released

Ann Arbor, Mich. - The Great Lakes Commission has released a toxic air
emissions inventory in a continuing effort to quantify the toxic air
emissions that impact air and water quality and communities of the Great
Lakes basin. The update, which reflects 1997 data, focuses on point, area
and mobile emissions from non-road and on-road sources.

This inventory represents the best single compilation of emissions data for
the Great Lakes basin. Funded by the U.S. Environmental Protection Agency
and managed by the Great Lakes Commission, the inventory effort is
undertaken by the air quality departments of the eight Great Lakes states
and the province of Ontario.

The new emissions inventory, which addresses 82 targeted toxic air
contaminants, found area sources to dominate the total emissions for 15 PAHs
(polycyclic aromatic hydrocarbons), 16 non-metal compounds, and one metal
compound. Point sources are responsible for more than two thirds of total
emissions for one PAH, 22 non-metal compounds and 11 metal compounds. Mobile
sources are responsible for most emissions of 11 non-metal compounds. Among
the target pollutants, toluene was estimated to have the highest emissions
at 516.5 million pounds, while 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)
emissions are the lowest recorded at 0.12 pounds.

According to Nathaniel E. Robinson, chair of the Great Lakes Commission,
"The new air toxic emissions inventory is the most comprehensive, high
quality regional inventory available. It's is a vitally important component
of our decision support system, and guides the region's policymaking and
research efforts."

In compiling the inventory, challenges were encountered in terms of data
breadth, quality, availability and consistency from one jurisdiction to the
next. Thus, this inventory should not be used to compare one state or
province's emissions against another's, but rather to demonstrate the
potential of such a comprehensive inventory as a decision support tool.

The inventory project strengthens decision-making capabilities in the region
by promoting interjurisdictional consistency in data collection and
analysis, establishing standard procedures and protocols, developing an
automated emission estimation and inventory system, and demonstrating the
value of Internet technology to exchange environmental data.

The Great Lakes states and Ontario, with management / technical support from
the Great Lakes Commission, are now compiling the next basinwide inventory
for the 1998 update, expected to be released in fall 2001. The Commission
also is preparing an update to its online AirMapper
(http://www.glc.org/air/airmapper.html), in addition to providing access to
the emissions inventory database online.

The Great Lakes Commission, chaired by Nathaniel E. Robinson (Wisconsin), is
a nonpartisan, binational compact agency created by state and U.S. federal
law and dedicated to promoting a strong economy, healthy environment and
high quality of life for the region and its residents. The Commission
consists of state legislators, agency officials and governors' appointees
from its eight member states. Associate membership for Ontario and Québec
was established through the signing of a "Declaration of Partnership." The
Commission maintains a formal Observer program involving U.S. and Canadian
federal agencies, tribal authorities, binational agencies and other regional
interests. The Commission offices are located in Ann Arbor, Michigan.
