Re:    New York Independent System Operator, Inc., Request to Withdraw August 23,
2010 Filing in Docket Nos. EL07-39-____, ER08-695-____, and ER10-2300-000

Dear Ms. Bose:

On August 23, 2010, the New York Independent System Operator, Inc. (“NYISO”) resubmitted is its August 12, 2010 compliance filing in response to the May 20, 2010 order (“August 12 Filing”),1 as directed by FERC Staff.  Specifically, on August 20, 2010, FERC Staff informed the NYISO that the August 12 Filing was rejected because it was submitted using an incorrect filing type code.  FERC Staff directed the NYISO to withdraw and
resubmit the August 12 Filing using the proper codes in the eTariff system.

However, when the NYISO made its August 23, 2010 resubmittal it inadvertently

omitted an attachment.  In order to correct the omission, the NYISO attempted to follow the
guidance provided in FERC’s online document titled FERC Staff Responses to Discussion
Questions from eTariff@ferc.gov. 2  This guidance would have required a selection of filing
type code 150 for submitting the attachment.  Unforeseeable limitations within the NYISO’s
eTariff filing software, however, would not allow the NYISO to perform functions under that
code.  The NYISO has alerted its eTariff software provider of the issue, but the problem will
take some time to resolve.

1 New York Independent System Operator, Inc., 131 FERC ¶ 61,070 (2010).

2 See Staff Responses to Discussion Questions from eTariff@ferc.gov at 30, question 4 (i.e., Type of
Filing Relation Question #4: “I forgot to include an attachment in a tariff filing.  How do I correct this
mistake?”), available at <http://www.ferc.gov/docs-filing/etariff/responses-discussion-questions.pdf>.

Ms. Kimberly D. Bose, Secretary August 24, 2010

Due to the inability to submit the omitted attachment without refiling all of the

documents, the NYISO submits this request to withdraw the August 23, 2010 resubmittal
filing.3

The NYISO will send an electronic link to this filing to the official representative of
each of its customers, to each participant on its stakeholder committees, to the New York
Public Service Commission, and to the electric utility regulatory agency of New Jersey.  In
addition, the complete filing will be posted on the NYISO’s website at www.nyiso.com.  This
is in accordance with 18 C.F.R. § 35.2(e).

The NYISO respectfully requests that the Commission accept this withdrawal for the reasons specified herein.

Respectfully submitted,

/s/Ted J. Murphy__________________
