Law enforcement agencies (LEAs) at all levels submit requests to ATF to trace guns used in crimes. So that ATF may swiftly and accurately provide responsive information on these crime guns, ATF requests LEAs to submit certain information on Form 3312.1 that will aid ATF in tracing the firearm. ATF reports the resulting information only to the requesting LEA and does not create a registry of firearms in the process. ATF is revising information collection (IC) OMB 1140–0043 to include an increase in respondents from 1,153 annually to 17,000 since the last renewal period, a difference of 15,847 per year. This is due to more law enforcement agencies submitting more trace requests each year. The adjustments therefore also include an increase in the total number of trace requests from 24,490 during the last renewal to 510,000 now. Consequently, the total burden hours have also increased from 2,449 to 51,000, resulting in a difference since the last renewal of 48,551 total annual hours.
