*New release of the Great Lakes Toxic Air Emissions Inventory*

Ann Arbor, Mich.—The Great Lakes Commission announces the release of its
updated Toxic Air Emissions Inventory in a continuing effort to quantify the
toxic air emissions that impact the waters and communities of the Great
Lakes basin.  The new inventory, using 1996 data, focuses on point and area
sources such as industrial facilities, small businesses and residential
units. Early next year, a new element of the inventory will be released that
addresses emissions from mobile sources such as motor vehicles and

This inventory represents the best single compilation of emissions data from
all eight Great Lakes states and the province of Ontario for point and area
sources.  Working cooperatively through the Great Lakes Commission, work on
the inventory is undertaken by the air quality departments of each Great
Lakes state and province of Ontario.

The new emissions inventory, which addresses 82 targeted toxic air
contaminants,  found the highest emissions in the Great Lakes basin  to be
Manganese at 3.251 million lbs/year and Chromium at almost 1.0 million
lbs/year. The top two PAHs (polycyclic aromatic hydrocarbons) were
Naphthalene at 13.8 million lbs/year and Phenanthrene at 6.4 million
lbs/year. The top two non-metals (not PAH) were Toluene at 265.2 million
lbs/year and Xylene (various forms) at 141.0 million lbs/year. For human and
environmental health effects of these and other toxics, visit

According to Orlando Cabrera-Rivera, chair of the Great Lakes Regional Air
Toxic Emissions Inventory Steering Committee, "The new air toxic emissions
inventory is the most comprehensive regional inventory available. It is very
important to continue to compile this inventory to provide accurate data to
scientific studies in the Great Lakes basin".

The objective of this ongoing partnership with the U.S. Environmental
Protection Agency is to provide researchers and policymakers with basinwide
data on the source and emission levels of toxic air contaminants.  The list
of targeted pollutants was increased from 49 during the 1993 inventory to 82
this year.  Part of the reason for the increase in the number of targeted
pollutants is the addition of mobile sources to the inventory.

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 decisionmaking capabilities in the basin
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 point and area sources for 1997 and 1998 data, expected to be completed
in late summer 2000.

The Great Lakes Commission is a nonpartisan, interstate compact agency
created by state and federal law and dedicated to promoting a strong
economy, healthy environment and high quality of life for the Great
Lakes-St. Lawrence region and its residents. The Commission consists of
state legislators, agency officials and governors' appointees from its eight
member states. It has a new Associate Member program for Canadian provinces
and also 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.
