Again both subcommittees refrained from pressing action on the 
legislation in order to await the final report of the United Nations 
Seabed Committee and the initiation of the Law of the Sea Conference. 
THE SECOND SESSION 
Finally, on January 28, 1974, Senator Metcalf and 6 cosponsors 
introduced Senate Amendment No. 946 (Appendix C) in the nature 
of a substitute for S. 1134. This legislation was first introduced as a 
new bill, S. 2878, on January 23, 1974, and referred to the Committee 
on Commerce. Consequently, i in order to continue hearings in the Com- 
mittee on Interior and Insular Affairs, Subcommittee on Minerals, 
Materials and Fuels, the sponsors introduced the same bill as Amend- 
ment No. 946 to 8. 1134. The companion bill, H.R. 12233, was intro- 
duced into the House by Representative Thomas Downing and 12 
cosponsors. Hearings were held by the House Subcommittee on Ocean- 
ography on February 26, 27, and 28, 1974.4* The Senate Subcommittee 
on Minerals, Materials and Fuels held hearings the following week.* 
In the Senate hearings, Subcommittee Chairman Metcalf stated: 
Our staff rewrote this legislation to meet the major objections of responsible 
spokesmen at previous hearings. As far as I know, the perfect piece of legislation 
has yet to be drafted. I am among those who have questions about the material 
before us. This, of course, is the reason for legislative hearings.” 
A number of basic changes were incorporated into Amendment No. 
946 so that it differed significantly from S. 1134. Among the changes 
made were: 
(1) Establishment of a moratorium on commercial development 
until January 1, 1976, to allow adequate time for international 
agreement through the Law of the Sea Conference according to 
the time frame regarded as adequate by Administration 
spokesmen. 
(2) Elimination of the subsurface block concept so that the 
leased area includes poly, the seabed and subfloor to a depth of 10
