1. New testing data on used oil New information on waste streams June 3, 2003

2. Four recent sources of UO data Vermont study Ecology transporter project Emerald Petroleum Settlement agreement Ecology used oil testing

3. Vermont study “Used Oil Analysis and Waste Oil Furnace Emissions Study” – April,1995 Does burning used oil in space heaters meet air quality and hazardous waste standards?

4. Vermont study slide 2 Emissions from used oil burning had elevated contaminant levels compared to burning No. 2 fuel oil Contaminant levels either met ambient air standards or were low enough that there were analytical detection and quantification problems

5. Ecology transporter project Sampling occurred in May, 2000 At the transporter facilities Samples were taken from used oil transporter storage tanks Unable to match specific generators to contaminants

6. Contamination frequently found Common contaminants were – Lead – Tetrachloroethene (aka perc) – Methylene chloride Ecology transporter project slide 2

7. Emerald Petroleum 21,000+ oil pickups made Nearly 8 million gallons of used oil collected 10 instances were subjected to closer analysis These 10 totaled 6,600 gallons – Automotive maintenance, auto wrecking yard, small aircraft maintenance, manufacturing plant maintenance shop, electrical equipment service, and small engine maintenance

8. Emerald Petroleum slide 2 All were investigated by Emerald and found to be legitimate, contamination through use. Small aircraft can still use leaded aviation gas, thus high lead levels in used oil Metals found: – Chrome, cadmium, lead – Arsenic tested for, but not found

9. Ecology sampling Collect oil directly from source Samples are still being collected Variety of sources Quick lube shopsAirport / small aircraft Railroad enginesCommercial truck engines Hydraulic systemsSmall engine repair / maintenance Marine diesel engines

10. Ecology sampling slide 2 Small sample set being collected Being used as a screening tool Data is not usable as generator knowledge When completed, results will be considered in light of other data

11. Ecology sampling slide 3 Tested for cadmium, chromium, lead, and arsenic – Some metals results are known – Small aircraft used oil is off-spec Lead: 2,210ppm to 4370ppm (totals) – No other sources are off-spec for metals so far Tested for Volatile Organics – No results from lab yet

12. What’s next ? Ecology used oil team will use data when re- examining used oil management Identify problems, propose solutions Team members are: Jim PearsonMichelle Underwood Tom CusackKerry Graber Tiffany YeltonJerry French Dave NightingaleVern Meinz Kevin Shanilec (EPA)
