An Errata correcting one of the associated subdockets listed in the August 25 Notice is being issued today, September 14, 2004. The August 25 Notice established September 8, 2004 as the deadline for submitting interventions or protests to August 18 filing.

The August 18 filing by AE Supply and the AE Supply Affiliates included proposed revisions to their tariffs associated with the harmonization of the Codes of Conduct among AE Supply and AE Supply Affiliates and proposed revisions associated with brokering provisions. Docket No. ER04-1197-000 has been assigned to the harmonization and brokering provisions included in the August 18, 2004 filing and those revisions are the subject of the instant notice.

Any person desiring to intervene or to protest the harmonization and brokering provisions in the August 18, 2004 filing must file in accordance with Rules 211 and 214 of the Commission's Rules of Practice and Procedure (18 CFR 385.211 and 385.214). Protests will be considered by the Commission in determining the appropriate action to be taken, but will not serve to make protestants parties to the proceeding. Any person wishing to become a party must file a notice of intervention or motion to intervene, as appropriate. Such notices, motions, or protests must be filed on or before the comment date. Anyone filing a motion to intervene or protest must serve a copy of that document on the Applicant. On or before the comment date, it is not necessary to serve motions to intervene or protests on persons other than the Applicant.
