Therefore, the Air Pollution Control Division of the Colorado Department of Public Health and Environment hereby gives NOTICE, pursuant to Section 25-7- 114.5(5), C.R.S. of the Colorado Air Quality Control Act that the Division received an application for an air pollution emission permit on the following proposed project and activity: The City of Greeley proposes to operate two (2) diesel powered electrical generators at the Water Pollution Treatment Facility for peak demand purposes. This source has two (2) diesel engines, one with a manufacturer design rating of 1,286 horsepower which is used to power a 900 kW generator, and one with a manufacturer design rating of 1,220 horsepower which is used to power a 750 kW generator. These generators have been used for emergency back-up power and will now be used for demand response purposes as well when there are heavy loads on the electrical grid. Because of the demand response capability, these generators have the potential to emit (PTE) a total of 235.5 tons of nitrogen oxides (NOx) per year. This PTE calculation was determined using manufacturer's emission factors and 8,760 hours of operation per year. This source has limitations written into the permits that will prohibit the generators from running more than 500 hours over a rolling 12-month period. These operational limitations bring the NOx emissions down to 13.5 tons per year for the generators. Because this source has the potential to emit greater than 100 tons per year of NOx, but is willing to accept operational limits to bring the NOx emissions below 100 tons per year, this source is considered to be a synthetic minor source for NOx. As such, these permits are subject to public comment per Regulation 3, Part B, Section III.C.1.d. Copies of the draft permits and preliminary analysis are available for review in the public comment package. The Division has determined that the proposed source will comply with all applicable regulations and standards of the Colorado Air Quality Control Commission and has made a preliminary determination of approval of the application. The Division hereby solicits and requests submission of public comment from any interested person concerning the aforesaid proposed project and activities to comply with the applicable standards and regulations of the Commission for a period of thirty (30) days from the date of this publication. Any such comment must be submitted in writing to the following addressee: Renee Mayer Colorado Department of Public Health and Environment 4300 Cherry Creek Drive South, APCD-SS-B 1 Denver, Colorado 80246-1530 Within thirty(30) days following the said thirty(30)-day period for public comment, the Division shall consider comments and, pursuant to Section 25-7-114.5(7)(a), either grant, deny, or grant with conditions, the emission permits. Said public comment is solicited to enable consideration of approval of and objections to the proposed construction of the subject project and activity by affected persons. A copy of the applications for the emission permits,the preliminary analysis of said applications, and accompanying data concerning the proposed project and activity are available for inspection at the office of the Clerk and Recorder of Weld County during regular business hours and at the office of the Air Pollution Control Division, Colorado Department of Public Health and Environment, 4300 Cherry Creek Drive South, Denver, Colorado. A copy of the draft permit and preliminary analysis are available on the Air Pollution Control Division's website at: http://www.cdphe.state.co.us/ap/airpublicnotices.html AIR POLLUTION CONTROL DIVISION PRELIMINARY ANALYSIS PERMIT NUMBER: 92WE1618-3 & 10WE2136 DATE: January 13, 2012 APPLICANT: City of Greeley ENGINEER: Renee Mayer CP SUPERVISOR: R K Hancock III, PE PROJECT DESCRIPTION The Water Pollution Treatment Facility listed below has applied for an air emission permit to operate two (2) diesel powered electrical generators for peak demand purposes. These generators will be used for peak demand response to ease the load on electrical grids when electrical power is in greatest need. These generators will also continue to be used for emergency purposes at the facility described below. These generators have the potential to emit (PTE) a total of 235.5 tons per year of nitrogen oxides (NOx). After operational limitations were placed on the generators, the NOx emissions will not exceed 13.5 tons per year. Because this source has PTE greater than 100 tons per year of a criteria pollutant, but will control emissions to levels below 100 tons per year, this source is classified as a synthetic minor facility. As a synthetic minor facility, this source is required to undergo a public comment process.
