Health studies industry concerns

Health Studies: Industry Concerns

  • Chromate Production Facilities – 1930s thru 1970s

    • Very high exposures, often of short duration

  • OSHA Uses Linear Model to Extrapolate Past Risks at Very High Levels to Much Lower Current Exposures

  • Expert review of Cr studies show different results

    • Crump Study – 23ug/m3 is protective

    • SBREFA process recommended 23 ug/m3 - Spring 2004

  • Uncertainty in OSHA’s Risk Assessment

Key

** In Health Benefits Analysis

* In Preliminary Quantitative Risk Analysis

# No statistically significant relationship between chrome exposure and lung cancer


Technical feasibility

Technical Feasibility

  • OSHA recommendations not appropriate

    • Systems cannot be “tweaked”

    • Fume suppressants not the answer

    • Engineering controls identified by OSHA not sufficient

  • Engineering Controls

    • OSHA’s data do not demonstrate technical feasibility

    • Difficult to achieve PEL lower than 10 ug/m3

    • Consistent compliance with action level needed

    • Process and sampling variability concerns

  • Substitutes and customer specifications limit process options

Compliance Cost of Proposed PEL:Metal Finishing Industry($/year, in millions)


Annual compliance costs

Economic impact analysis

Economic Impact Analysis

  • OSHA – No Significant Impacts

    • Based on Low Estimated Compliance Costs

    • Average Costs Compared to Average Ability to Pay

    • Did not Differentiate Large from Small Facilities

  • Industry – Proposed PEL Would Close More than Half the Industry

    • Critique OSHA’s Crude Economic Impact Analysis

    • Use EPA’s MP&M Economic Impact Analysis

      • 50% Closure at $61,000/Facility/Year

    • Detailed Affordability Case Studies for 6 Facilities

Benefit cost assessment industry review

Benefit-Cost Assessment:Industry Review

  • OSHA Asserts Total Benefits from the PEL Exceed Costs by $140 million annually (includes health benefits across all affected sectors)

  • Industry Analysis Launched to:

    • Formulate new cost estimates vs. OSHA cost estimates

    • Review how OSHA arrived at benefits estimates

    • Evaluate analytical methods and additional health studies and recalculate benefits

  • Goal: Credibly Compare Costs and Benefits for Alternative PELs

    • Position – Net benefits should be positive for any final PEL

    • Conclusion – Even without changing OSHA compliance cost estimates, benefits are much less than costs

    • Conclusion – OSHA drastically underestimated costs


Re calculated benefits

Re-Calculated Benefits

  • Instead of using cancer slope range estimated from only 2 studies, use average of all 6 studies cited by OSHA

  • Use best estimate for cancer latency, not OSHA’s range

  • Apply more accurate Value of Statistical Life estimate

  • For purposes of this calculation, accept most of OSHA’s other estimates
