The Wise Report

 From the TCEQ:  The TCEQ is seeking volunteers from environmental interest and local government groups, consultants and environmental managers to participate in two staff-led subcommittees developing guidance for the Texas Risk Reduction Program (TRRP) rule with input from the TRRP Steering Committee. The planned documents will address representative concentrations for ecological exposure (TRRP-15E) and human exposure (TRRP-15H). The objective of both documents is to describe acceptable techniques for using environmental sample data to determine if and to what extent response actions are needed at a contaminated site. 
 TRRP-15E will address such topics as:

  • Determining exposure areas for benthic invertebrates and wildlife
  • Unique considerations for background determination for sediment
  • Determining exposure point concentrations for benthic invertebrates and wildlife
  • Considerations of hot spots for ecological receptors
  • Composite sampling to support ecological risk assessments

 TRRP-15H will address such topics as:

  • Comparing sample results to standards
  • Determination of background concentrations
  • Exposure areas for grouping of data
  • Response action determination process with application to specific exposure pathways
  • Requirements for use of statistics as specified in the TRRP rule

Interested volunteers should ideally have familiarity with one or more of these topics for either ecological or human exposure as well as knowledge of related general guidance and the TRRP rule. Participation will involve frequent meetings at TCEQ headquarters in Austin, joining in conference calls, or commenting on draft documents. The number or role of participants may be limited based on the number of volunteers. An organizational meeting to orient volunteers will be scheduled in mid-to-late October, 2008. Contact Paul S. Lewis at (512) 239-2341 or Plewis@tceq.state.tx.us by 9/15/08 to volunteer or for information.
