SUPPLEMENTARY INFORMATION: As a result of the enactment of the Coast Guard Authorization Act of 2010, codified at 46 U.S.C. 12102, the Secretary of Transportation has the discretionary authority to issue waivers allowing documented vessels with registry endorsements or foreign flag vessels to be used in operations that treat aquaculture fish for or protect aquaculture fish from disease, parasitic infestation, or other threats to their health when suitable vessels of the United States are not available that could perform those services. The Secretary has delegated this authority to the Maritime Administrator. Pursuant to this authority, MARAD is providing notice of the services proposed by Cook Aquaculture (Cook) in order to make a U.S.-flag vessel availability determination. In order to comply with USCG Aquaculture Support regulations at 46 CFR part 106, Cook is seeking a MARAD Aquaculture Waiver to operate the vessels M/V COLBY PERCE and M/V RONJA CARRIER as follows: Intended Commercial Use of Vessel: ‘‘to use two highly-specialized foreignflag vessels referred to as ‘‘wellboats’’ (or ‘‘live fish carriers’’) to treat Cooke’s swimming inventory of farmed Atlantic salmon in the company’s salt-water grow-out pens off Maine’s North Atlantic Coast. This treatment prevents against parasitic infestation by sea lice that is highly destructive to the salmon’s health.’’ Geographic Region: ‘‘Off Maine’s North Atlantic Coast’’. Requested Time Period: ‘‘2017 calendar year, from January 1, 2017 to December 31, 2017’’. Interested parties may submit comments providing detailed information relating to the availability of U.S.-flag vessels to perform the required aquaculture support services. If MARAD determines, in accordance with 46 U.S.C. 12102(d)(1) and MARAD’s regulations at 46 CFR part 388, that suitable U.S.-flag vessels are available to perform the required services, a waiver will not be granted.

PHMSA further advises the public not to use any DOT–39 cylinder with an internal volume greater than 75 in3 (1.23 L) containing a liquefied flammable compressed gas. pmangrum on DSK3GDR082PROD with NOTICES Safety Concern The release of a liquefied flammable compressed gas from or rupture of such a cylinder having an internal volume exceeding 75 in3 (1.23 L) is a safety concern that could result in extensive property damage, serious personal injury, or even death. A liquefied flammable compressed gas has a stored energy that is several times greater than that of a non-liquefied compressed gas. Further, a DOT–39 cylinder can have a volume of up to 1,526 in3 (25 L) at a service pressure of 500 psig or less and, as such, can have up to 22 times the stored energy of a DOT–39 cylinder limited to 75 in3 (1.23 L). Additionally, because of the design specifications that allow for thinner walls when used at lower pressure, the cylinders may be at greater risk from corrosion or puncture. Given the known risks associated with cylinders that are filled with liquefied flammable compressed gases, PHMSA is issuing this safety advisory notice to inform offerors and users of DOT–39 cylinders that cylinders with an internal volume of 75 in3 (1.23 L) or more should not be filled with liquefied flammable compressed gas. Background This safety advisory notice is being issued in part because of concern over confusion about the regulatory requirements when using DOT–39 cylinders for liquefied compressed gases. Historically, the Hazardous Materials Regulations (HMR; 49 CFR parts 171–180) limited the internal volume of a DOT–39 specification cylinder to 75 in3 (1.23 L) when used for certain liquefied flammable compressed gases. This size limitation applied when DOT–39 cylinders were used for gases that were subject to Note 9 following the table at § 173.304(a)(2) or liquefied petroleum gas as addressed in § 173.304(d)(3) (The table is currently located at § 173.304a). In an October 30, 1998 notice of proposed rulemaking (NPRM), the Research and Special Programs Administration (RSPA)—the predecessor agency to PHMSA— VerDate Sep<11>2014 15:08 Dec 12, 2016 Jkt 241001 proposed to extend the 75 in3 (1.23 L) volume limitation of DOT–39 cylinders to all liquefied flammable compressed gases by revising § 173.304 to delete Note 9 from the table at § 173.304(a)(2) and adding §§ 173.304a and 173.304b.1 RSPA received several comments in opposition to extending the limit to all liquefied flammable compressed gases which would have been codified in § 173.304a(a)(3). RSPA published a final rule on August 8, 2002 and, based on the opposing comments, decided not to extend the 75 in3 (1.23 L) limitation to all liquefied flammable compressed gases in a DOT–39 cylinder at that time. However, in the process of publishing the final rule, the agency inadvertently omitted the 75 in3 (1.23 L) limitation for liquefied flammable compressed gas and liquefied petroleum gas.2 On November 13, 2014, PHMSA accepted a petition for rulemaking (P– 1622) from Worthington Cylinders to address this error in a rulemaking.

Background BILLING CODE 4910–60–P A key component of PHMSA’s pipeline safety regulations is its integrity management (IM) program. For gas transmission pipelines, this program is outlined in Subpart O of 49 CFR part 192 and is based on the concept that pipeline operators need to identify those segments of their pipeline systems that pose the greatest risk to human life, property, and the environment, and to take extra precautions to ensure their safety. These higher-risk areas are known as ‘‘HCAs.’’ Each operator is required to survey its entire pipeline system to identify all pipeline segments 1 NPRM—Hazardous Materials: Requirements for DOT Specification Cylinders (HM–220D) [63 FR 58460]. 2 Final Rule—Hazardous Materials: Requirements for Maintenance, Requalification, Repair and Use of DOT Specification Cylinders (HM–220D) [67 FR 51625] 3 https://www.gpo.gov/fdsys/pkg/FR-2016-07-26/ pdf/2016-16689.pdf.

SUPPLEMENTARY INFORMATION: 

Public Action Requested

    PHMSA advises offerors of DOT-39 cylinders having an internal 
volume exceeding 75 cubic inches (in\3\) (1.23 L) that such cylinders 
should not be filled with liquefied flammable compressed gas. PHMSA 
further advises the public not to use any DOT-39 cylinder with an 
internal volume greater than 75 in\3\ (1.23 L) containing a liquefied 
flammable compressed gas.

Safety Concern

    The release of a liquefied flammable compressed gas from or rupture 
of such a cylinder having an internal volume exceeding 75 in\3\ (1.23 
L) is a safety concern that could result in extensive property damage, 
serious personal injury, or even death. A liquefied flammable 
compressed gas has a stored energy that is several times greater than 
that of a non-liquefied compressed gas. Further, a DOT-39 cylinder can 
have a volume of up to 1,526 in\3\ (25 L) at a service pressure of 500 
psig or less and, as such, can have up to 22 times the stored energy of 
a DOT-39 cylinder limited to 75 in\3\ (1.23 L). Additionally, because 
of the design specifications that allow for thinner walls when used at 
lower pressure, the cylinders may be at greater risk from corrosion or 
puncture. Given the known risks associated with cylinders that are 
filled with liquefied flammable compressed gases, PHMSA is issuing this 
safety advisory notice to inform offerors and users of DOT-39 cylinders 
that cylinders with an internal volume of 75 in\3\ (1.23 L) or more 
should not be filled with liquefied flammable compressed gas.

Background

    This safety advisory notice is being issued in part because of 
concern over confusion about the regulatory requirements when using 
DOT-39 cylinders for liquefied compressed gases. Historically, the 
Hazardous Materials Regulations (HMR; 49 CFR parts 171-180) limited the 
internal volume of a DOT-39 specification cylinder to 75 in\3\ (1.23 L) 
when used for certain liquefied flammable compressed gases. This size 
limitation applied when DOT-39 cylinders were used for gases that were 
subject to Note 9 following the table at Sec.  173.304(a)(2) or 
liquefied petroleum gas as addressed in Sec.  173.304(d)(3) (The table 
is currently located at Sec.  173.304a).
    In an October 30, 1998 notice of proposed rulemaking (NPRM), the 
Research and Special Programs Administration (RSPA)--the predecessor 
agency to PHMSA--proposed to extend the 75 in\3\ (1.23 L) volume 
limitation of DOT-39 cylinders to all liquefied flammable compressed 
gases by revising Sec.  173.304 to delete Note 9 from the table at 
Sec.  173.304(a)(2) and adding Sec. Sec.  173.304a and 173.304b.\1\ 
RSPA received several comments in opposition to extending the limit to 
all liquefied flammable compressed gases which would have been codified 
in Sec.  173.304a(a)(3). RSPA published a final rule on August 8, 2002 
and, based on the opposing comments, decided not to extend the 75 in\3\ 
(1.23 L) limitation to all liquefied flammable compressed gases in a 
DOT-39 cylinder at that time. However, in the process of publishing the 
final rule, the agency inadvertently omitted the 75 in\3\ (1.23 L) 
limitation for liquefied flammable compressed gas and liquefied 
petroleum gas.\2\
