If 20 or fewer requests to provide public comments are submitted, each speaker shall be limited to three minutes per item. If between 21 and 30 speakers submit public comments, each speaker shall be limited to two minutes per item. If more than 30 speakers submit public comments, each speaker shall be limited to 90 seconds per item. The time limit per speaker shall be established based on the number of requests to speak submitted to the Recording Secretary before the first speaker is called. Requests to speak submitted after the first speaker is called shall receive 90 seconds. These time limits may be shortened or extended, or a cumulative limit on the time for all public speakers may be imposted, at the discretion of the Chair or by a majority vote of the Commission.
