Changes of PCB Regulations May Impact Management of Certain Classes of PCB-Containing Items On-board Vessels, as well as Applications for Foreign Transfers of Vessels
On April 7, 2010, the U.S. Environmental Protection Agency (EPA) published an Advance Notice of Proposed Rulemaking (ANPRM) in the Federal Register (75 Fed Reg. 17,645) initiating the reassessment of polychlorinated biphenyl (PCB) use authorizations. PCB compounds have been regulated by the EPA under the Toxic Substances Control Act (TSCA) since 1977. EPA believes that the balance of risks and benefits from the continued use of remaining equipment containing PCBs may have changed enough since 1977 to consider amending the regulations to phase-out the continued use of PCB containing articles. This ANPRM is being used by the EPA to collect information which it will consider when reassessing PCB use and the need for an amendment to the PCB regulations.
The ANPRM solicits information from the maritime industry regarding PCBs on vessels. Because this solicits voluntary comments, no action is necessary. The comment period closed on August 20, 2010.
EPA’s solicitation raises several issues which have the potential to impact the maritime industry.
In this ANPRM, the EPA asked many different industries to assess the importance of PCB-containing equipment on their current and future operations. EPA poses the following specific questions to vessel owners and operators:
1. In what vessel systems is PCB containing equipment still in use on vessels?
2. What percentage of vessel equipment uses liquid PCBs?
3. What percentage of vessel equipment uses non-liquid PCBs?
4. What is the expected life of equipment containing PCBs on vessels now in service before it requires routine servicing?
5. What is the difference in the locations used for liquid filled equipment, versus non-liquid filled equipment located?
6. How much does it cost to identify and test (sample collection, extraction, chemical analysis, and recordkeeping) liquid filled equipment and/or nonliquid filled equipment on vessels to determine the PCB concentration?
7. Other than chemical analysis, what methods (such as application type, nameplate, model number, manufacturer name, etc.) can be used to identify PCB-containing equipment?
8. Do non-liquid PCBs enclosed in cabling pose any greater risk to the health of the public than liquid PCBs enclosed in cabling?
9. Should the ‘‘totally enclosed’’ exemption accorded to liquid PCBs enclosed in cabling be extended to solid PCBs?”
(Reference: 75 FR 17665, April 7, 2010)
Why are these questions and this regulatory change important to the maritime industry?
The phase-out of PCB-containing equipment and the lowering of the threshold PCB benchmark concentration have the potential to impact maritime equipment and material management and replacement practices. The potential regulatory changes may also impact how MARAD and the EPA administer applications for transfer of a US Flagged vessel to another registry or a foreign owner.
The suspect presence of PCBs in vessel equipment and material has a direct and immediate impact on applications for foreign vessel transfers. Changes in the PCB regulations lowering the PCB benchmark concentration below 50 ppm will confound the process.
EPA’s involvement in the vessel transfer approval stems from the TSCA prohibit ion of the export of PCBs at concentrations above 50ppm. MARAD’s approval for foreign vessel transfer is contingent on the EPA’s assessment.
MARAD and the EPA have not yet published an interagency procedure to integrate the EPA’s PCB review process into the MARAD foreign vessel transfer program. We anticipate an announcement from MARAD of an interagency Memorandum of Understanding (MOU) which formally incorporates EPA’s PCB review procedures and authorities within the administration of the MARAD program. When this interagency MOU is published we will provide you with our assessment of its implications to the vessel transfer process.
