### Interrogatory No. 8 

### For each TVA EGU, please identify any pollution control equipment currently installed, evaluated in engineering studies, orplanned to be installedbetween the presenttime and the year 2020, and operating on the EGU, including butnot limited to, sulfur oxide "scrubbers," electrostaticprecipitators, selective catalyst or noncatalytic reduction equipment (SCRor SNC;R), low NOx 

### combustion controls, baghouses, activated carbon injection, and dust collectors. Foreach piece of equipment identified, include the manufacturer, size, design capacity, design control efficiency, operational control efficiency, the capital and installation costs ofthe equipment, and the date ofinstallation and startup, orplanned installation and startup. Responseto No. 8 

### TVAobjects to provide the requested information regarding pollution control equipment evaluated in

### Interrogatory No. 9 Starting with the year 1975 and including all subsequent years up to and including the presentidentify with respect to each TVA EGU any (1) notices received under Section 114 ofthe federal Clean Air Act, 42 U.S.C. § 7414 or similar state statute orrule; (2) notices received ofviolation or orders under Section 113 ofthe federal Clean Air Act, 42 U.S.C. 7413, or similar state statute or rule; or (3) letters or other communications received from State orfederal regulatory agencies with respect to inadequacies,.inconsistencies, orviolations ofpermit conditions. 

### Response 

### to No.9 TVA objects to this Interrogatory because it seeks information that is not relevant to any claim ordefense inthis action, and the request is not reasonably calculated to lead to the discovery ofadmissibleevidence. Inparticular, notices of violation and information requests issued as far back as 1975 could have no conceivable relevance to this lawsuit, which is limitedto forward-looking injunctive relief. TV A also objects to the request toprovide information regarding "communications
... with respect to inadequacies [or] inconsistencies
... ofpermit conditions." Those terms are not defmed inPlaintifrs Interrogatories, and TVA does not understand what information is being requested. Subjectto and without waiver ofits objections, TVA states that ithas located the following responsive information: 1. On January 9, 2006 Cumberland Fossil Plant received a Notice of Violation that was issued by the Tennessee Department ofEnvirorunent and Conservation citing excess visible emissions from a boiler stack and failure to operate a baghouse onthe limestone handling system.
