Oak Ridge Reservation

Oak Ridge Reservation Health Effects Subcommittee (ORRHES)

ORRHES Subcommittee

The Oak Ridge Reservation Health Effects Subcommittee (ORRHES) was established in 1999 by Agency for Toxic Substances and Disease Registry (ATSDR) and the Centers for Disease Control and Prevention (CDC). The purpose of ORRHES was to give advice and recommendations about off-site public health activities and research conducted by ATSDR and CDC at the Department of Energy's Oak Ridge Reservation, in Tennessee. Further, this subcommittee provided a public forum for communication and collaborations between the citizens and agencies that evaluated public health issues and conducted public health activities at the Oak Ridge Reservation. 
The ORRHES accomplished the following:

  • Served as a citizen advisory group to CDC and ATSDR and gave recommendations on public  health activities and research at the Oak Ridge Reservation.
  • Allowed  citizens to communicate  with agency staff members and learn more about the public health assessment process and other public health activities.
  • Provided input in developing ATSDR’s public health assessments and other public health activities which included
    • presentations by national experts
    • technical workshops
    • evaluations and critiques of scientific issues
  • Helped to prioritize

    public health issues and community concerns reviewed by ATSDR.

ORRHES Subcommittee Activities

The ORRHES Subcommittee engaged in a number of activities to support its public health mission. Some of these activities included holding public meetings and establishing work groups as follows:

Public Meetings

The members of the subcommittee sought to involve and talk to with those who were interested in and affected by ATSDR and CDC public health activities at the Oak Ridge Reservation. The ORRHES Subcommittee also encouraged the public to provide input to the federal agencies and to learn about public health activities at the Oak Ridge Reservation.

ORRHES created a series of formal programs to inform and have meaningful conversations with the public in the affected communities. The ORRHES held 26 public meetings in the Oak Ridge area from 2000-2005. The minutes of the ORRHES are available for review.

Work Groups

The ORRHES created workgroups in the ATSDR Oak Ridge Field Office in Oak Ridge, TN to fulfill its mission for providing advice and recommendations to ATSDR on public health activities in critical areas. To help ensure participation, the meetings of the subcommittee’s work groups were open to the public.

ATSDR scientists presented detailed technical data and information on the public health assessments at the work group meetings. Between 2000-2005, ORRHES work groups met more than 125 times. The minutes of work group meetings  are available for review.
