PIB: Program Information Bulletin. Information bulletins provide information of a temporary nature; they do not provide policy or procedural instructions. Information bulletins do not have an effective date or an expiration date; a bulletin is intended to be kept as long as each recipient needs it. When it is no longer needed, it may be destroyed.
PIL and PPL: Procedure Instruction Letter and Program Policy Letter. Policy letters state agency policy, meaning an interpretation or clarification of a regulation. Policy letters are temporary supplements to the Program Policy Manual (PPM).
PILs and PPLs are intended for the mining community as well as MSHA enforcement personnel and, therefore, are distributed to both groups.
Copies of PIBs, PILs, PPLs and PPM are located on the MSHA Compliance Information page.
