Standards of Performance for New Stationary Sources: Volatile Organic Compound Emissions From the Synthetic Organic Chemical Manufacturing Industry Wastewater; Supplement to Proposed Rule

On September 12, 1994, the EPA proposed Standards of Performance for New Stationary Sources: Volatile Organic Compound Emissions from the Synthetic Organic Chemical Manufacturing Industry Wastewater. On October 11, 1995, the EPA issued a supplement to the proposal. The action proposed today clarifies and revises the previously proposed rule and proposes to add Appendix J to part 60. Volatile organic compounds (VOC), when emitted into the ambient air, are precursors to the formation of tropospheric ozone. A wide variety of acute and chronic respiratory health effects and welfare (e.g., agricultural, ecosystem) effects have been attributed to concentrations of ozone commonly measured in the ambient air throughout the U.S. Appendix J to part 60, How to Determine Henry's Law Constants, Fm Values, Fr Values, and Fe Values for Organic Compounds, is being proposed today. This appendix provides the methodology for determining Henry's law constants, fraction measured (Fm) values, fraction removed values (Fr), and fraction emitted (Fe) values.
