Emission Data 8a What emission test report(s), parametric monitoring data, and other data or monitoring are available for boilers noted in Part I, Question 15, for tests conducted since January 1, 2005. Please consider reports prepared for all testing and monitoring programs, for all pollutants, including those required under Title V, compliance with State or local requirements, fulfillment of contractural obligations, US Department of Energy (DOE) programs, etc. (Note:EPA is not requesting copies of the test reports or data at this time; however, we may request actual copies in the future.) -Flint Creek has performed filterable and condensible particulate emissions and CO tests on March 5, 2006. 8b. Please indicate the date(s) and types (e.g., stack, fuel, parametric, etc.) of the test(s) and constituents (including criteria and hazardous air pollutants) sampled for. Date: March 8, 2006 Type: Stack Constituents: Filterable and Condensible Particulate Matter and CO

8c. Do any of thse test reoprts reflect testing at a location upstream of any emission control devices? 7. In addition to the analyses required in 3 for which analyses of chlorine and/or any of the HAP metals were conducted, please provide copies of any analyses conducted over the preceding 12 calendar months for (a) complete proximate and ultimate analyses, (b) additional trace metals, and (c) the mineralogy of the ash that are readily available for the oil or coal listed in 2.

Did the unit's control configuration differ from that shown in Part I, question 16, at the time of these test results?

If yes, please list the unit's complete control configuration at the time of testing in a similar format to Part I, question 16.

________ ________ 8e. Do any of these test reports reflect testing during periods of startup, shutdown, and malfunction?

If yes, please note which reports and identify the other material(s) or non-fossil fuels used.

________

10. Are deviation reports available for malfunctions or other periods of noncompliance with permit terms and conditions?

Deviation reports are available in the quarterly reporting required by

the Title V permit. 8g. Do any of these test reports reflect testing at a location upstream of a post combustion SO2 emission control device (e.g.FGD, SDA, Dry Scrubber)? If yes, please note which reports and provide a detailed description of the location of the emission sampling point(s) (question 8c above), include detail about how m uch , if any, bypass of unscrubbed flue gas was utilized at the tim e of testing (including percentage of total scrubber exhaust flow). Note by diagram where sampling ports were located in relation to

the bypass ductwork.
