1. Cory R. Chadwick, Director Hamilton County DOES (HCDOES) October 5, 2011

2.  Complainants, environmental groups, and citizens have historically voiced two main concerns: What is in the air I am breathing Odor no longer present when investigator arrives  Started in the City of Cincinnati in 1999  Expanded by HCDOES in 2002 to all four counties in SW Ohio

3.  Fifteen – 6L canisters utilized in four county area  Citizen keeps evacuated canister and takes sample as needed (outdoor only)  Citizens trained how to take sample, record weather information, and use chain of custody  Take sample when odor is strongest  After taking sample, complainant calls hotline

4.  Hotline call initiates field investigation  Inspector picks up canister and arranges for canister to be shipped to approved lab  Samples typically analyzed using US EPA Method TO-15  Additional analysis if particular compound of concern (CO, Methane, Sulfur, etc.)

5.  Canisters used for both instantaneous and 24-hr samples  Program also uses real time monitoring (stand alone or in conjunction with canister program) Photo Ionization Detector (PID) – ppb level of VOCs Multi-Rae – ppm range VOCs, CO, H2S, LEL and Oxygen Flame Ionization Detector (FID) – ppm Methane and VOC PID Multi-Rae FID

6.  Complainants call in less, stop calling, or even decide not to take sample (waiting for really bad odor)  Gives the complainant some control in evaluating the odor present  Communication of sampling results very important  Toxicologist review if needed (none on staff)  Not a tell all – just tool in our toolbox

7.  Canisters cost approx. $500 per can  Analysis is around $250 per can, more if special compounds requested  Average cans used per year is 10 -12  Analysis cost $2,500 to $3,000 per year  Penalty dollars used to purchase cans  Analysis costs covered by penalty and regular budget
