process, the amount of Chemical X that is lost through the process vent on an annual basis can be estimated as follows: Input = Amount purchased (8,000 pounds) Output = Product (24,000 lbs x 25 %) + waste (10,000 lbs x 15 %) + process vent loss Input = Output 8,000 lbs Chemical X = 6,000 lbs + 1,500 lbs + process vent loss Process vent loss = 8,000 - 6,000 - 1,500 = 500 lbs Chemical X per year 3. Method E : Emission Factors published in the EPA document AP -42, or those al- ready approved by LRAPA, or those developed specifically for your facility, are all acceptable means of estimation of air emissions, unless monitoring data are available. AP -42, "Compilation of Air Pollutant Emission Factors," 5 th edition, is available at: (1) LRAPA office, (2) University of Oregon library, or (3) on the In- ternet at http: / /www.epa.gov /ttn/chief/ap42 /index.html. 4. Method O : When no data exist and document - driven estimation methods are not available, a business may use its best engineering judgment in calculating reportable quantities. When engineering calculations are appropriate, businesses are encouraged to consult EPA 560/4 -88 -002, "Estimating Releases and Waste Treatment Efficiencies for the Toxic Chemical Release Inventory Form," Dec. 1987 at http: / /nepis.epa.gov/Exe /ZyNET. exe/ 10003BA2 .TXT ?ZyActionD= ZyDocument &Client = EPA &Index = 1986 +Thru +1 990 &Docs = &Query= FNAME%3D 10003B A2.
