## Abstract This is an AJministrative AmenJment to correct a date reference in DAQE-ANO102380020-09. The original ahstract is includeJ helow. On April I5. 2()()8. PacifiCorp Energy suhmitteJ an NOi to install new emissions control equipment at the Huntington Power Plant on the Unit #I boiler in order to substantially reduce plant emissions. The NOi was supplemented with CO modeling information in January 2009. The new emissions control equipment will consist oflow-NO, burners, replacement ofthe ESP with a fabric filter. and upgrade of the flue gas Jesulfurization system. In addition, PacifiCorp Energy is requesting plantwide applicability limits for S02 and NO, emissions. along with loweremission limits at Unit#I for those same pollutants. The installation ofthe low-NO, burners on Unit #1 may increase CO emissions. In addition. past PTE emissions ofCO were estimated using now-outdated emission factors. These two issues result in a new PTE for CO above the PSD significance threshold of 100 tons per year. Therefore a PSD modification for CO is required. The Unit#l and #2 boilers are subject to NSPS Subpart D. Title IV and Title V ofthe 1990 Clean Air Act apply to this source. The Title V Operating Permit will be updated priorto operating the modified equipment. The source is located in Emery County. which is an attainment area for all pollutants. After the installation and upgrades ofthe control equipment. the emissions from the #1 boiler, in tons per year, will change as follows: PMrn = -835, NO,= -546. 

### S02 = -13.921. CO= +7.109, VOC = +25. and H2SO.i = -14.8. The change in emissions will result in the following. in tons per year, totals for the plant: PM 10 = 925, NO, = I 1,356. 

### S02 = 5,220. CO= 14.218, VOC = 119, and H2S04 = 1.6. Established PALs for the plant include the PSD significance level of40 tons peryear, and are set at NO,= J1,396 tons/year and 

### S02 = 5.260tons/year based on a 12-month rolling average. This airquality AO authorizes the project with the following conditions and failure tocomply with any of the conditions may constitute a violation ofthis order. This AO is issued to, and applies to the following:
