In petition P-1619, the Chlorine Institute requested that updates to publications currently listed in § 171.7(l)—specifically § 171.7(l)(1), (2), (5), and (12)—and referenced in various sections of the HMR be incorporated by reference. PHMSA conducted a review of these publications and found them suitable to propose incorporation into the HMR. In the NPRM, PHMSA proposed to include the following updated documents in the referenced material:
Chlorine Institute Emergency Kit “A” for 100-lb. & 150-lb. Chlorine Cylinders, Edition 12, Revision 2, July 2014
Emergency Kit “A” is designed for use with the standard DOT 3A480 and 3AA480 100 and 150-pound capacity cylinders in chlorine service only. Emergency Kit “A” contains devices and tools to contain leaks in and around the cylinder valve and in the side wall of chlorine cylinders. The Chlorine Institute Emergency Kit “A” is the only chlorine emergency kit for chlorine cylinders that is manufactured to the design specifications of the Chlorine Institute. Under certain circumstances U.S. DOT regulations permit transportation of a chlorine cylinder with an Emergency Kit “A”. See 49 CFR 173.3(e).
Chlorine Institute Emergency Kit “B” for Chlorine Ton Containers, Edition 11, Revision 1, July 2014
Emergency Kit “B” is designed for use with the standard DOT 106A500X chlorine ton container and can also be used with 110A500W in chlorine service. Emergency Kit “B” contains devices and tools to contain leaks in and around the ton container valves and in the side wall of ton containers. The Chlorine Institute Emergency Kit “B” is the only chlorine emergency kit for ton containers that is manufactured to the design specifications of The Chlorine Institute. Under certain circumstances, U.S. DOT regulations permit transportation of a chlorine ton container with an Emergency Kit “B”. See 49 CFR 173.3(e).
Pamphlet 57, Emergency Shut-Off Systems for Bulk Transfer of Chlorine, Edition 6, June 2015
This pamphlet covers the recommended practices for emergency shut-off protection during chlorine transfers involving bulk containers.
Pamphlet 168, Guidelines for Dual Valve Systems for Bulk Chlorine Transport, Edition 2, July 2015
The purpose of this pamphlet is to set forth performance/selection criteria that should be utilized in identifying dual valve systems for bulk chlorine transportation applications (i.e., tank cars, cargo tanks and barges). These configurations are intended to meet U.S. Department of Transportation (DOT) and Transport Canada (TC) performance requirements. This pamphlet contains information pertaining to standardizations, performance/design criteria, operational considerations and installation considerations, as well as an appendix that includes valve manufacturer information.
PHMSA received comments from the Chlorine Institute in relation to this petition. The Chlorine Institute supported PHMSA’s incorporation of the IBR documents. The Chlorine Institute further believed that this would eliminate the need for certain special permits (specifically SP-16102, which allows transportation of equipment designed in accordance with Edition 11, Revision 1, of the Emergency Kit “B” (B-Kit) instruction booklet). PHMSA agrees and is, therefore, adopting the changes in § 171.7(l) to incorporate the most recent Chlorine Institute publications as proposed.
