Any person may attend any meeting involving a substantial interest matter unless that meeting has been listed as a closed meeting. For meetings not involving substantial interest matters, the chairperson of the meeting may exercise his or her discretion to allow attendance by a member of the public.

When meetings between Agency employees and outside parties are open to the public, attendance may be limited by space. When feasible, a person or organization desiring to attend such a meeting should give at least one day advance notice to one of the employees holding or attending the meeting so that sufficient space can be arranged for all those wishing to attend.

Members of the public attending Agency meetings generally may observe only. The chairperson of the meeting may exercise his or her discretion to permit members of the public to participate as well.

The following Agency meetings are not open to the public:

Meetings, or, if possible, portions of meetings where the General Counsel or his or her designee has determined that proprietary data are to be discussed in such a manner as to imperil their confidentiality;

Meetings held by outside parties at which limits on attendance are imposed by lack of space, provided that such meetings are open to the news media;

Meetings with outside parties held during the normal course of surveillance, inspection, or investigation under any of the Acts administered by the Commission, including informal citation hearings under the Federal Hazardous Substances Act or the Poison Prevention Packaging Act;

Meetings with outside parties concerning the settlement or negotiation of an individual case, including proposed remedial action, or meetings concerning any administrative or judicial action in which the outside party is a participant, party, or amicus curiae;

Meetings with other Federal personnel that are attended by outside parties except where a specific matter to be discussed is also pending before the Commission or its staff;

Meetings between Agency staff (other than Commissioners and their personal staff) and an outside party when the General Counsel or his or her designee determines that extraordinary circumstances require that the meeting be closed. Requests for exemption by members of the staff who report to the Executive Director may be submitted to the General Counsel or his or her designee in writing only by the Executive Director or his or her designee. In such a case, the reasons for closing the meeting or a portion of the meeting shall be stated in the Public Calendar notice announcing the meeting;

Meetings between a Commissioner (or his or her personal staff) and an outside party when, in the opinion of the Commissioner, extraordinary circumstances require that the meeting be closed. In such a case, the reasons for closing the meeting or a portion of the meeting must be stated in the Public Calendar notice announcing the meeting;
