Urgent: Request for Release of Information 

From Docket No. EPA-HQ-OW-2009-0819 

***PROMPT RESPONSE REQUESTED*** 

Dear Mr. Covington and Mr. Jordan: 

I believe that Public Service ofNew Hampshire (PSNH) has provided information 

regarding our power plants that is being used by EPA in the development of the proposed 

revisions to the effluent limitations guidelines and standards for the steam electric power 

generating point source category, i.e., the "ELG Rule." I believe the information was 

provided either via responses to earlier ELG Rule questionnaires to the industry or by 

separate information requests made by EPA directly to PSNH. The specific facilities in 

question are as follows: 

Merrimack Station 

Newington Station 

Schiller Station 

NPDES Permit No. NH0001465 

NPDES Permit No. NH0001601 

NPDES Permit No. NH0001473 

We have identified certain record documents which we believe contain information 

reported by, or derived from data or information reported by, one or more of our 

facilities. EPA has redacted all or portions of these documents as "confidential business 

information" (CBI). 

We are requesting that you provide to PSNH all information related to our facilities listed 

above (including information that EPA has derived from information obtained from our 

facilities and from all other sources, and including facility-specific or facility-derived 

information in input files to the listed documents) contained within the following 

documents:

Please include all information from these documents that relates to our three facilities. 

For example, our facilities supplied information about existing control technologies. 

Through this request, we are requesting not only the control technologies information 

supplied by our facilities, but also control technologies information about our facilities 

derived from other sources, as well as all EPA-developed information relating to our 

control technologies, including EPA's assessments of future technology choices for our 

facilities based on the various rule options. 

For each document, as appropriate, please also include: (1) a legend which explains each 

column heading and each abbreviation used throughout the entire document; and (2) a list 

of all formulas applied in the document and a legend for any abbreviations used in the 

formulas. The legend and formula information is key to understanding these documents. 

We make this request without waiving any of our CBI designations. Because you are 

providing the information only to us, there is no breach of confidentiality and no waiver 

of CBI protections. Furthermore, we are not requesting CBI information, or CBI-derived 

2 
information, from other companies that may have furnished data or information 

appearing in the listed documents. We are requesting only information related to our 

own facilities. 

We have done our best to be selective in asking for facility-specific information. The 

information we are seeking, however, is critical to our review of, and preparation of 

comments on, the proposed ELG Rule. Because there are less than 50 days left in the 

comment period, we ask that you expedite this request. 

If you have any questions about this request, please feel free to contact me via email or 

by calling 603-634-2439. I look forward to your prompt response. Thank you very much 

for your help. 

Very truly yours, 

Allan G. Palmer 

Senior Engineer
