3 Community-Scale Air Toxics Study Toxics Monitoring Around a Kraft Pulp and Paper Mill in Lewiston, Idaho

4 PartnersResponsibility Nez Perce Tribe, Environmental Restoration and Waste Management Division Air Quality Program Administer project Operate reservation sampling sites Idaho Department of Environmental Quality, Lewiston Office and Boise Modeling Group Operate off-reservation sampling sites and Modeling Washington State University, Laboratory for Atmospheric Research (Pullman, WA) Modeling RJ Lee Group, Inc., Center for Laboratory Sciences (Pasco, WA) Sample analysis Potlatch Corporation Idaho Pulp and Paperboard Meteorological data from facility tower and emissions data U.S. Environmental Protection Agency Region 10 Funding, Guidance

5 Sampling locations

6 Particulate metals PM10 Hi-Vol. Quartz microfiber filters EPA method IO-3.5 Volatile Organic Compounds ATEC 2200 sampler canisters EPA method TO-15 Carbonyls ATEC 2200 sampler DNPH cartridges EPA method TO-11A Benzene, carbon tetrachloride, chloroform, 1,3-butadiene, 1,2-dichloropropane, methylene chloride, tetrachloroethylene, trichlororethylene, vinyl chloride Arsenic, beryllium, cadmium, chromium, lead, manganese, nickel Formaldehyde, Acetaldehyde 24 h samples; EPA’s one in six day sampling schedule; 5/1/2006-4/30/2007

7 Nez Perce County Demographic Comparison Expect lower concentrations than in other U.S. data.

8 Potential Concern FormaldehydeAcetaldehyde BenzeneCarbon tetrachloride Tetrachloroethylene1,3-Butadiene ArsenicManganese >50% detects exceed the chronic screening threshold

9 Chronic Inhalation Cancer Risk Comparison 30-year chronic cancer risk screening values from EPA Region 3 and highest annual mean concentrations from any site in the Lewiston study were used to generate estimated risk numbers.
