The Paperwork Reduction Act of 1995 requires agencies to publish proposed information collections in the Federal Register for public comment before an agency can use the process (generally a form) to collect information from the public. As required by the Paperwork Reduction Act, this notice provides 60 days for public comment on the revision of an existing collection. The proposed information collection pertains to the marking of explosives which enables law enforcement entities to more effectively trace explosives from the manufacturer through the distribution chain to the end purchaser. This process is used as a tool in criminal enforcement activities.
