Technical Advisory Committee

About the Committee

The Technical Advisory Committee (TAC) is a voluntary collection of ISOSWO members who share an interest in solid waste/material management and collaborate to provide input/feedback on proposed guidance, policies, regulations and/or laws that govern/guide the industry. The collaboration generally occurs between committee members and the Iowa Department of Natural Resources (IDNR) but can extend to the U.S. Environmental Protection Agency (EPA).

Iowa DNR Environmental Covenant Template (1/6/2019)

TAC worked with the IDNR to roll out guidance on the process to secure environmental covenants on landfill properties as a step toward reducing or terminating the post-closure care period. Additionally, the TAC provided feedback to the IDNR on proposed rules associated with Waste Conversion Technologies. In 2019, the TAC has tentatively planned to collaborate on developing:

  • Criteria or guidance to more effectively permit evapotranspirative landfill caps
  • Potential approach to evaluating metals parameters in groundwater using a risked-based approach
  • Potential implementation of a statewide laboratory analytical database storage program that promotes improved evaluation of parameters for statewide trends, reduction of analysis, and/or background variability.

Please use the Environmental Covenant template developed by the IDNR for use in gathering, coordinating and submitting the necessary information to acquire an environmental covenant. This is a step that the ISOSWO Technical Advisory Committee and the IDNR have collaborated on to assist facilities in more effectively navigating the reduction or termination of the post-closure care period. If you have any questions, please contact Mike Smith, IDNR at 515.725.8314.
