NYMEX Submission 05.204

Re: Clarifying Amendments to NYMEX SO2 and NOX Emissions Allowance
Futures Contracts

Dear Ms. Jean Webb:

The New York Mercantile Exchange, Inc. ("NYMEX" or the "Exchange") is
notifying the Commodity Futures Trading Commission (“CFTC” or “Commission”) that
in Submission 05.158 from September 8, 2005 some of the rule amendment language was
inadvertently left out. Rules 783.09 for NOX, and 782.09 for SO2 were amended to
clarify that some of the delivery information specified by the rules would be exchanged
directly between the customer’s clearing members and not through the Notices of
Intention through the Exchange’s Clearing Department. The material previously
submitted indicated the amendment for the long clearing member, but not for the short
clearing member. These amendments for the short clearing member are indicated in the
attached rules (see section (B) (2) of both rules).

Pursuant to Section Sc(c) of the Commodity Exchange Act (“Act”) and CFTC
Rule 40.6, the Exchange hereby certifies that this clarification complies with the Act,
including regulations under the Act.

Should you have any questions concerning the above, please contact Jay Gottlieb,
Director, Research, at (212) 299-2607; or the undersigned at (212) 299-2390.

Very truly yours,

Robert A. Levin
Senior Vice President, Research
