Open Comment Periods
PHMSA regularly issues rulemakings that propose changes to the HMR, and we encourage stakeholders to participate by submitting comments. In order to view which rulemakings have an open comment period, please click on the "NPRM & ANPRM" link in the Rulemaking Menu on the top right of this page. Lastly, click on each individual rulemaking to view its comment period (open or closed).
