1 Services, inc. ~ Dominion 120 Tredegar Street, Richmond, VA ~r Energy Dominion Energy.com The Honorable James Richard Perry Secretary of the Energy United States Department of Energy 1000 Independence Aye, SW Washington, DC September 26, 2018 Re: Report on Yorktown Units 1 & 2 Operations Pursuant to Order No Dear Secretary Perry: Pursuant to Order No dated September 5, 2016 ( Order ) by the Secretary of Energy ( Secretary ), PJM Interconnection, LLC. ( PJM ) and Virginia Electric and Power Company ( Dominion ) respectfully submit the attached air emissions report and water usage report regarding PJM s dispatch of Yorktown Units I and 2 from September II through September 24, including the periods needed to startup and ramp down the units. This report is submitted in accordance with the Secretary s directive in the directive in the Order that every two weeks PJM and Dominion are to report all dates between September 10, 2018 and December 8, 2018, on which Yorktown Units I and/or 2 are operated, and the associated air emissions and water usage data for those dates. In the Order, the Secretary determined that an emergency continues to exist in the North Hampton Roads area of Virginia due to a shortage of electric energy and a shortage of facilities for the generation of electric energy. 2 The Secretary also found in both orders that the issuance of the orders will meet the emergency and serve the public interest as required by Federal Power Act Section 202(c).3 In doing so, the Secretary directed Dominion to operate Yorktown Units I and/or 2 as directed by PJM only as needed to ensure grid reliability for a 90-day period of September 10 through December 8,201 8.~ As shown in the September 10 report regarding PJM s dispatch of the Yorktown Units I and 2, on September 3 at approximately 8:00 hundred hours, PJM dispatched Unit 2 on line, the unit was on line September Order at page 2. 2 June Order at page I; September Order at page I. Id. June Order at page 2; September Order at page 2.

2 at approximately 12:00 hundred hours, and Unit 2 was operating at 23:59 hundred hours on September 10, the end of the reporting period. Unit 2 remained operating until PJM dispatched the unit off line on September22 at approximately 6:00 hundred hours, and the unit dropped offline at approximately 10:00 hundred hours. On September24 at approximately 8:00 hundred hours, PJM directed Unit 2 to be available September25 at 8:00 hundred hours, which is outside this reporting period. On September 12 at approximately 7:00 hundred hours, PJM directed Yorktown Unit Ito be on line at 11:00 hundred hours on September 13, and the unit was operational at approximately 8:00 hundred hours on September 13. On September 14 PJM directed the unit off line and the unit went offline at approximately 2:00 hundred hours. hours on September 17, and Unit I On September 16 PJM directed Unit Ito be on line by 10:00 hundred was operational on September 17 at approximately 4:00 hundred hours. Unit I remained operational until September 22 when PJM ordered Unit I offline, and the unit dropped offline at approximately 2:00 hundred hours on September 22. On September24 at approximately 8:00 hundred hours, PJM directed Unit Ito be available September25 at 8:00 hundred hours, which is outside this reporting period. Attachment I to this report is the Yorktown Power Station for September 10 through September24 that shows the actual runtime and air emissions data for Units I and 2. This spreadsheet includes hourly runtime data for Yorktown Units I and 2, hourly gross Megawatt (MW) outputs, and raw and calculated data showing air emissions data associated with operations of Yorktown Units I and 2.~ The information in Attachment I reports Yorktown Units I and 2 hourly emissions of PM-I 0 and SO2 in pounds per hour, and mercury in pounds per hour, for the operating period September II through September 24. Additionally for the same time period, Attachment 1 provides Units I and 2 hourly emissions of NOx in pounds per hour, greenhouse gases (as CO2) in tons per hour, lead in pounds per hour, HCI in pounds per hour, in pounds per hour, and CO in pounds per hour. NOx and S02 The Yorktown units can emit pollution while not generating MWs (e.g. during standby, startup and shutdown sequences). Thus, Attachment I shows the MW output during the period Yorktown Units I and 2 provided power to the grid including startup and shutdown processes, and it shows the emissions data for operations of Units I and 2 including times when the unit was not generating power. 2

3 emissions are based on valid hours of Continuous Emissions Monitoring System (CEMS) data for the period. PM-i 0 emissions are based on the emission factor derived from the July21, 2017 stack test ( lbs/mrnbtu corrected to lbs/mmbtu calculated for PM-b filterable plus condensable). C02 emissions are based on valid CEMS hours for the operating period. All other emissions were calculated using emission factors from AP-42, Fifth Edition, Volume 1, Chapter 1: External Combustion Sources and calculated hourly coal consumption in tons. 6 Attachment 2 to this report is the Yorktown Units I and 2 September 11 through September 24 Circulating Water Usage report for the unit operations required by the Orders. Operation of cooling water pumps extends over a period of time longer than unit operation to facilitate cooling of plant components that support the boiler and turbine. As a general rule cooling water will start to be pumped before the unit is started and continue to be pumped until the turbine metal temperature is less than 300 F. Sometimes additional cooling water is necessary to complete proper cool down of auxiliary equipment and lubrication fluids after the turbine metal reaches 300 F, as was the case with the operations of the Yorktown Units September Ii through September 24. As shown in Attachment 2, water circulated through Unit I from September 11-16, and water started to be circulated through Unit I on September 24 in anticipation of running the unit September 25. Also shown in Attachment 2, water circulated through Unit 2 September 11-24, and water started to be circulated through Unit 2 on September24 in anticipation of running the unit September 25. PJM and Dominion respectfully submit the information in this report be accepted by the Secretary as compliant with the Secretary s directives in the Order that every two weeks PJM and Dominion are to report all dates on which Yorktown Units I and/or 2 are operated for the period September 11 through September 24, and the associated air emissions and water usage data for those dates. 6 and lead emissions were calculated using AP-42, Table CO emissions were calculated using emission factors from AP-42, Table Total HAP metals and individual HAP metals are not provided because MATS Table 2 (40 CFR 63, Subpart UUUUU) provides for compliance with either the PM limit or total non-mercury HAP metals limits or individual HAP metals. Dominion is providing PM-b emissions for the purposes of MATS. HCI and emissions were calculated using emission factors from AP-42, Table
