On July 16, 2013 (78 FR 42457 / HM–257), the Pipeline and Hazardous Materials Safety Administration (PHMSA) published a final rule revising the Hazardous Materials Regulations applicable to the approval of Division 1.4G consumer fireworks (UN0336 Fireworks) and establishing DOT approved fireworks certification agencies that provide an alternative to the approval process for Division 1.4G consumer fireworks. PHMSA is also reformatting the procedural regulations pertaining to certification agencies. These actions clarify regulations with respect to PHMSA’s fireworks approval process and provide regulatory flexibility in seeking authorization for the transportation of Division 1.4G consumer fireworks. Based on the August 30, 2012, NPRM (77 FR 52636) under Docket No. PHMSA 2010–0320 (HM–257), and comments received, this final rule adopts an alternative option for Division 1.4G consumer fireworks in which manufacturers may submit applications for certification to a DOT-approved Fireworks Certification Agency (FCA), in lieu of submitting applications for approval to PHMSA. To ensure oversight of FCAs, this final rule includes reporting and recordkeeping requirements. Additionally, PHMSA defines consumer fireworks and clarifies the approval process for designation as an FCA. The differences between this final rule and the NPRM include: removing the requirement that an FCA must physically examine a firework device; clarifying the FCA certification process; reformatting the certification process for other DOT-approved agencies; removing the requirement that an FCA must be inspected by PHMSA prior to approval; adding preamble discussion regarding the information that will be contained in the FCA approval documentation issued by PHMSA; revising the alphanumeric scheme for fireworks certified by FCAs; and clarifying the content of the approval issued by PHMSA for designation as an FCA. The effective date for this final rule is August 15, 2013.
