PHMSA respects your right to privacy and will protect it when you visit our website. PHMSA collects no personal information about you when you visit our website unless you specifically and knowingly choose to provide such information to us. If you choose to provide information to us, we use it only to fulfill your request for information or services.

Information made available to the public and request for confidential treatment. (49 CFR Part 105.30)

When you submit information to PHMSA during a rulemaking proceeding, as part of your application for special permit or approval, or for any other reason, we may make that information publicly available unless you ask that we keep the information confidential.

(a) Asking for confidential treatment. You may ask us to give confidential treatment to information you give to the agency by taking the following steps:

  1. Mark "confidential" on each page of the original document you would like to keep confidential.
  2. Send us, along with the original document, a second copy of the original document with the confidential information deleted.
  3. Explain why the information you are submitting is confidential (for example, it is exempt from mandatory public disclosure under the Freedom of Information Act, 5 U.S.C. 552 or it is information referred to in 18 U.S.C. 1905).

(b) PHMSA Decision. PHMSA will decide whether or not to treat your information as confidential. We will notify you, in writing, of a decision to grant or deny confidentiality at least five days before the information is publicly disclosed, and give you an opportunity to respond.
