60-Day HMSP Renewal Period

As of March 31st, a change in the hazardous materials safety permit (HMSP) application process allows carriers to renew their MCS 150B sixty (60) days before the carrier's HMSP expires. Previously, a renewal application was considered an update if received more than thirty (30) days before the HMSP expiration.

Carriers may continue to operate under an existing HMSP until they are required to renew according to the schedule in 49 CFR 390.19. Carriers are encouraged to use the 60-day grace period before the current permit expires to correct any noncompliance issues that may impact their HMSP renewal. This change will be stated in the Biennial Update Letter mailed to carriers approximately 60 days prior to the renewal schedule.
