  1. Effectiveness of TUR Assistance • Determined by analysis of TURA data • Numerous perspectives taken • Independent econometric analysis also conducted • Extensive peer review • Methodology refined over two-year period

  2. Key Challenges • Measuring reductions in use in a way that is comparable across all sizes • Measuring reductions in a way that is invariant for production changes • Comparing performance in ways that don’t suffer from data distortions or input bias

  3. Key Virtues • Existence of large TURA data set • Over one-thousand companies • Over a decade of annual reports • Over one hundred chemicals • Input/Output • Production Ratios

  4. Primary Parameter • Production-adjusted Reduction in Use • Generated by multiplying PR by base year use to derive “expected use”, and comparing to actual use in given year • Normalized by interpreting reduction as percentage of expected use

  5. Comparing Before and After Performance • 3143 data points: 1787 after, 1356 before • Averages for the groups must be weighted for comparison • Variance statistically significant? • After: 13.3% reductions • Before: 7.7%

  6. Advancers/Decliners • Another way of measuring whether you are helping to improve performance • Could also use byproduct or byproduct/use • Different than measuring positive or negative reductions – looks at the direction of change

  7. Byproduct/Use • Doesn’t need production adjustment • Complements Use Reduction tracking • Doesn’t need normalizing for size • Can compare change in ratio over time

  8. Dropouts • Dropouts for business reasons less important than chemical reductions • One third dropped out by doing TUR • One sixth business, one sixth exemptions • 26% of nonvisited claimed TUR • 46% of visited claimed TUR

  9. Independent Analysis • Econometrics a way of assessing the explanatory value of a factor • Does the visit explain the reductions seen? • 45 chemicals had enough data • 25 selected for time considerations • 15 showed statistically significant reductions related to the visits – in either use or byproduct

  10. Reviews • NPPR Summit Work in Progress Presentation • EPA Region One presentation • Internal OTA and EOEA reviews • Secretary’s Science Advisory Board • All Day Subcommittee Review • Final Paper Review before SAB

  11. Conclusions • TURA has resulted in hundreds of millions of pounds of reductions • OTA’s visits are associated with tens of millions of pounds of reductions • Cost/benefit analysis as conventionally performed could assign a zero dollar value to this result without more information

  12. P2 Valuation • Chemical reductions reduce workplace risks, enhance productivity • Transportation, storage, transfer accidents reduced • Releases and wastes reduced • Costs of management reduced • Products made safer
