New testing data on used oil

New information on waste streams

June 3, 2003

Four recent sources of UO data

Vermont study Ecology transporter project Emerald Petroleum Settlement agreement Ecology used oil testing

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?

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

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

Contamination frequently found Common contaminants were

– Lead– Tetrachloroethene (aka perc)– Methylene chloride

Ecology transporter project slide 2

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

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

Ecology sampling

Collect oil directly from source Samples are still being collected Variety of sources

Quick lube shops Airport / small aircraft

Railroad engines Commercial truck engines

Hydraulic systems Small engine repair / maintenance

Marine diesel engines

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

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

What’s next ?

Ecology used oil team will use data when re-examining used oil management

Identify problems, propose solutions Team members are:
