On September 25, 2001, the New York Independent System Operator, Inc. (NYISO) filed with the Federal Energy Regulatory Commission (Commission),  
revisions to its Market Administration and Control Area Services Tariff (Services Tariff) and its Open-Access Transmission Tariff (OATT) to make
permanent two temporary market rules pertaining to External Transactions that were initially implemented as  Extraordinary Corrective Actions, and to introduce several new enhancements to its external transaction scheduling processes:  1) provisions to ensure that Exports are evaluated consistently for purposes of scheduling and curtailment by incorporating the concept of "Sink Price Cap Bids" into, and by eliminating the concept of "default" Decremental Bids, and 2) revising the time priod within which it will perform the Balancing Market Evaluation (BME).  Currently NYISO runs BME 90 minutes ahead of each dispatch hour.  The revisions would allow NYISO to use BME at any time no later than 90 minutes before the hour.    The NYISO has
     requested a waiver of the usual sixty day notice period so that
     this filing can become effective on October 30, 2001.
