New testing data on used oil

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
Ecology transporter project slide 2

• Contamination frequently found
• Common contaminants were
• Lead
• Tetrachloroethene (aka perc)
• Methylene chloride

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 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

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
Whats next ?

• Ecology used oil team will use data when
  re-examining used oil management
• Identify problems, propose solutions
• Team members are
