IRIS Public Meeting Logistics

IRIS Calendar of Events IRIS Calendar

Attending in Person

When IRIS public science meetings are held in-person, then the EPA Conference Center is where they would be held. The conference center is located at One Potomac Yard, 2777 South Crystal Drive, Arlington, Virginia 22202 (see map).

Only individuals registered for in-person attendance will be allowed into the EPA building to attend these events.

EPA Facility Access:

To enter the facility, you must check in at the guard’s desk (no more than 1 hour before the meeting) in the building lobby with your photo identification. Effective July 21, 2014, under the REAL ID Act requirements, not all state-issued driver’s licenses are acceptable as photo ID for security purposes. In EPA headquarters buildings (including the Potomac Yard buildings), driver’s licenses from the following states/territory, which do not comply with the REAL ID Act, will not be accepted as a photo ID.  Visitors from these states/territory must present other forms of ID to be permitted entry. Visit the REAL ID website for more information.

Note: Please allow 10-20 minutes extra time to go through security.

Participation Details

Public participation. The IRIS Program uses a meeting format intended to promote public discussion which emphasizes conversational exchanges over presentations. We would like to hear the full range of scientific perspectives during these discussions. Accordingly, we request that no more than two individuals from the same organization register as discussants on any particular topic. We also ask that discussants limit the number of slides used, and rely on them mainly to present concepts and data via figures and tables. After the discussants have had a turn, all meeting participants will be invited to join the discussion.

  • Submitting written comments: You may provide comments or additional information on the materials provided by using the chemical docket as specified on each meeting announcement.
  • Submitting studies: If you are aware of published studies that may provide new or additional data for this assessment, we ask that you submit them to the chemical specific docket.
  • Comments during the meeting: Both remote attendees and individuals attending in person are invited to make comments and ask questions during this meeting. Additional time will be given to address as many questions as possible after EPA subject matter experts and discussants have spoken.

Disclosures for discussants and commenters. To promote transparency, it is requested that persons submitting written or oral comments or participating as discussants on key science topics disclose: (1) The nature of any financial relationships (e.g., consulting agreements, expert witness support, or research funding) they may have with any organization(s) or entities having an interest in the assessment or issues under discussion; and (2) The extent to which their comments were reviewed by an interested party prior to submission.

Disclosures for submitting study results. If results or analyses of scientific research are submitted or presented, it is requested that the following information be provided where available: (1) Identification of the funding source(s) and sponsoring organization(s) of the research; (2) The extent to which the research findings were reviewed by an interested party prior to publication or submission, and identification of any such parties; and (3) The nature of any financial relationships between investigators who conducted the research and any organization(s) or entities having an interest in the assessment or issues under discussion.

Making submitted materials available to the public. To provide a reasonable opportunity for all stakeholders to participate in a thoughtful public dialogue on the science topics, and to help ensure they have enough time to adequately prepare prior to the meeting, EPA would like to make all comments and meeting visual aids available to the public prior to the meeting. Therefore, meeting participants are requested to submit these materials to the individual chemical docket and to in advance of the IRIS public meeting. Materials submitted to the docket will become available to the public shortly after submission. To provide time for all participants to prepare to contribute to the dialogue, the latest date to submit materials to the docket is 1 week before the meeting for all summary visual aids to be used during the meeting.
