Environmental Protection Agency risk management

U.S. Environmental Protection Agency, Risk Management Programsfor Chemical Accidental Release Prevention Proposed Rule Tide 40, Part 68, Subpart B, of the Code of Eederal Regulations (40 CER 68), Federal Register 54212 (Oct. 20,1993). 

Where complete containment is impractical, exhaust ventilation (preferably to a scrubber) can limit or eliminate exposure to toxic materials. The exhaust ventilation rate (velocity or volumetric rate) may be calculable for volatile liquids from spill size and vapor pressure (U.S. Environmental Protection Agency, Risk Management Program Guidance for Offsite Consequence Analysis, Appendix D, Equation D-l, 1999), but tests to determine concentrations in air usually would be needed for dusty processes and fugitive releases of gases.

There are a multitude of governmental requirements for the manufacture and handling of isocyanates. The U.S. Environmental Protection Agency (EPA) mandates testing and risk management for TDl and MDl under Toxic Substance Control Administration (TSCA). Annual reports on emissions of both isocyanates are required by the EPA under SARA 313.

The remaining Sections e.xainine tluce important topics as tliey relate to the subject title of tliis book. Section 2.7 reviews the details of the U.S. Environmental Protection Agency s (USEPA s) Risk Management Program while Section 2.8 provides information on the Occupational Health and Safety Administration (OSHA). The chapter continues with a short Section (2.9) on potential environmental violations and then concludes with a Section (2.10) on tlic Pollution Prevention Act of 1990.

The California Air Resources Board has prepared risk assessments for a number of toxic airborne compounds and mixtures, designated as toxic air contaminants, TACs (Table 16.15). For example, risk assessments for individual compounds such as benzene, benzo[a]pyrene (see Chapter 10), formaldehyde, and vinyl chloride have been carried out, in addition to complex mixtures such as diesel exhaust (California Air Resources Board, 1997a) and environmental tobacco smoke (California Environmental Protection Agency, 1997). These risk assessment documents form the basis for controls imposed as part of the risk management process (e.g., see Seiber, 1996).
