Purpose of the Study• Participate in the National Ambient Air

Toxics Monitoring Strategy• Characterize the degree and extent of

local-scale air toxics concerns• Provide information for the community

and State and Local government to identify the need for implementing risk reduction strategies

NYS Department of Environmental ConservationNYS Department of Environmental Conservation

Why Was Tonawanda Selected ?

• Community concerns about ambient concentrations of benzene and other compounds

• EPA’s 1999 National Air Toxics Assessment (NATA) for Erie County

• Coke Oven Residual Risk Assessment prepared by EPA

Page 4: Tonawanda Community Air Quality Study...Tonawanda Community Air Quality Study New York State Department of Environmental Conservation National Air Monitoring Conference November 4,

NYS Department of Environmental ConservationNYS Department of Environmental Conservation

Tonawanda Study Plan

• Collect monitoring data from 4 sites for 1 year• Analyze pollutant specific data

– Evaluate influence of wind direction on monitored concentrations

– Compare annual average concentrations to health- based guidelines and characterize risk

– Assess emissions and potential contribution to monitored concentrations

• Mobile sources, large (major) and small (area) industrial, and manufacturing sources

Page 5: Tonawanda Community Air Quality Study...Tonawanda Community Air Quality Study New York State Department of Environmental Conservation National Air Monitoring Conference November 4,

NYS Department of Environmental ConservationNYS Department of Environmental Conservation

Tonawanda Study Plan

• Enhance emission inventory for large and small sources

• Model these emissions to:– Allow for comparison to monitored values– Allow for analysis of previously modeled air toxics

(EPA’s NATA)– Evaluate a new multi-facility modeling tool

developed by EPA– Evaluate previous Coke Oven modeling results,

conducted for Residual Risk Assessment

Air Toxics Measured

• 44 Volatile Organic Compounds (VOCs) and 12 Carbonyls

• 1 in 6 day sampling schedule (24 hour samples)

• 15 of the chemicals are high priority urban air toxics targeted for reductions by the 1990 Clean Air Act

Air Toxics Results

• Presenting results for 6 compounds– Five had annual results above the AGC– One was of concern to the community

• 9 additional compounds had results with consistent detectable concentrations but below the AGC

Conclusion (given at start of last public meeting)

The results of the community air quality monitoring study and data analysis indicates there is a need for a focused effort to reduce the burden of air toxics in the Tonawanda area.

Risk Assessment Terminology• What is an Annual Guideline

Concentration (AGC)?• What is non-cancer risk?• What is cancer risk?

Page 52: Tonawanda Community Air Quality Study...Tonawanda Community Air Quality Study New York State Department of Environmental Conservation National Air Monitoring Conference November 4,

NYS Department of Environmental ConservationNYS Department of Environmental Conservation

Non-Cancer RiskThe risk associated with health effects

other than cancer that have AGCs based on animal or human toxicity studies. The AGC represents a value that is likely to be without appreciable risk of harmful effects during a lifetime.

Page 53: Tonawanda Community Air Quality Study...Tonawanda Community Air Quality Study New York State Department of Environmental Conservation National Air Monitoring Conference November 4,

NYS Department of Environmental ConservationNYS Department of Environmental Conservation

Cancer RiskOne in one million – the AGC represents

the likelihood that up to one person, out of one million equally exposed people would contract cancer if exposed continuously (24 hrs/day) to that concentration over a lifetime.
