All changes to the DMMP program since its inception have been through the SMARM process: papers proposing updates are presented, public comments are taken, and proposals are then adopted as originally presented, modified based on comments, or not implemented at all.
DMMP identifies three kinds of papers: Issue, Clarification and Status.
- Issue papers propose program-level changes that require approval by all four DMMP agency directors in order to implement.
- Clarification papers propose updates and modifications to existing guidance that do not substantively change program or policy.
- Status papers are for information only. Status papers may report on current investigations that may eventually result in an Issue or Clarification, or they may simply be information of interest to stakeholders.
