Re: Rule Certification. NYMEX Submission 05-139: Notification of Approved
Amendment to Supplement No. 1, “Official List of Approved Brands and Markings”
of the Grade 1 Copper Futures Contract.

Dear CFTC Commissioners:

The New York Mercantile Exchange, Inc. ("NYMEX" or the "Exchange") is notifying the Commodity
Futures Trading Commission (““CFTC” or “Commission”) of approved amendments to Supplement No.
1, “Official List of Approved Brands and Markings” of the Grade 1 Copper Futures Contract to be
implemented effective Friday, August 12, 2005. The approved amendments change the production status
of the following copper brands produced by BHP Copper Inc. to no longer produced: (1) BHP Copper;
and (2) BHP Copper/SXEW. These brands will be marked with an asterisk (*) to indicate that they are
no longer produced. The BHP Copper and the BHP Copper/SXEW brands will continue to remain
acceptable for delivery against the Grade 1 Copper Futures Contract since there are copper cathodes
bearing these brands in Exchange Licensed Warehouses for Copper.

Pursuant to Section 5c(c) of the Commodity Exchange Act (“Act”) and CFTC Rule 40.6, the Exchange

hereby certifies that the attached rule amendment complies with the Act, including regulations under the
Act. This approved amendment will go into effect on Friday, August 12, 2005.

Should you have any questions concerning the above, please contact Albert J. Getz at (212) 299-2608.

Very truly yours,

Robert A. Levin
Senior Vice President - Research
