APPENDIX B THE COAST GUARD AUTHORIZATION ACT OF 1998 Section 423, "Double Hull Alternative Designs Study," states, as follows: Section 4115(e) of the Oil Pollution Act of 1990 (46 U.S.C 3703a note) is amended by adding at the end thereof the following: "(3)(A) The Secretary of Transportation shall coordinate with the Marine Board of the NRC to conduct the necessary research and devel- opment of a rationally based equivalency assessment approach, which accounts for the overall environmental performance of alternative tank vessel designs. Notwithstanding the Coast Guard opinion of the appli- cation of sections 101 and 311 of the Clean Water Act (33 USC 1251 and 1321), the intent of this study is to establish an equivalency evaluation procedure that maintains a high standard of environmental protection, while encouraging innovative ship design. The study shall include: "(i) development of a generalized cost spill data base, which in- cludes all relevant costs such as clean-up costs and environmental impact costs as a function of spill size; (ii) refinement of the probability density functions used to es- tablish the extent of vessel damage, based on the latest available his- torical damage statistics, and current research on the crashworthiness of tank vessel structures; (iii) development of a rationally based approach for calculating an environmental index, to assess overall outflow performance due to collisions and groundings; and (iv) application of the proposed index to double hull tank vessels and alternative designs currently under consideration. "(B) A Marine Board committee shall be established not later than 2 months after the date of enactment of the Coast Guard Authorization Act of 1998. The Secretary of Transportation shall submit to the Committee on Commerce, Science, and Transportation of the Senate and the Committee on Transportation and Infrastructure in the House of Representatives a report on the results of the study not later than 12 months after the date of enactment of the Coast Guard Authorization Act of 1998." 123
