Section 5.5 - Public contacts in informal rulemaking(a)Agency contacts with the public during informal rulemakings conducted in accordance with 5 U.S.C. 553 .(1) DOT personnel may have meetings or other contacts with interested members of the public concerning an informal rulemaking under 5 U.S.C. 553 or similar procedures at any stage of the rulemaking process, provided the substance of material information submitted by the public that DOT relies on in proposing or finalizing the rule is adequately disclosed and described in the public rulemaking docket such that all interested parties have notice of the information and an opportunity to comment on its accuracy and relevance.(2) During the pendency of a rulemaking proceeding, DOT personnel must avoid giving persons outside the executive branch information regarding the rulemaking that is not available generally to the public.(3) If DOT receives an unusually large number of requests for meetings with interested members of the public during the comment period for a proposed rule or after the close of the comment period, the issuing OA or component of OST should consider whether there is a need to extend or reopen the comment period, to allow for submission of a second round of "reply comments," or to hold a public meeting on the proposed rule.(4) If the issuing OA or OST component meets with interested persons on the rulemaking after the close of the comment period, it should be open to giving other interested persons a similar opportunity to meet.(5) If DOT learns of significant new information, such as new studies or data, after the close of the comment period that the issuing OA or OST component wishes to rely upon in finalizing the rule, the OA or OST component should reopen the comment period to give the public an opportunity to comment on the new information. If the new information is likely to result in a change to the rule that is not within the scope of the notice of proposed rulemaking (NPRM), the OA or OST component should consider issuing a supplemental NPRM to ensure that the final rule represents a logical outgrowth of DOT's proposal.
