Therefore, the Division of Air Pollution Control of the Colorado Department of Health, hereby gives NOTICE pursuant to Section 25-7-114(4)(e), C.R.S. 1973, as amended, of the Colorado "Air Quality Control Act", that an application to the Division has been received for an emission permit on the following proposed project and activity: Weld County, Mining Division, has proposed to construct gravel crushing equipment to be located in Hall Pit at 83rd/WCR 62 in Weld County, Colorado.This plant, rated at 200 tons per hour (TPH), will consist of an assembly of a crusher and a power generating set. The expected air pollutant emissions from this operation are estimated as follows: Particulate Matter (TSP): 8.06 Particulate Matter < 10 pm PM10 1.10 The Division has determined that the source will comply with all permitting requirements. The Division hereby solicits and requests submission of public comment concerning the aforesaid proposed project and activity for a period of thirty (30) days from and after the date of this publication. Any such comment must be in writing and be submitted to the following addressee: Sunday A. Fadeyi Construction Permit Section Stationary Sources Program Air Pollution Control Division Colorado Department of Public Health and Environment 4300 Cherry Creek Drive South APCD-SS-B1 Denver, Colorado 80222-1530 (more) 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(4)(f)(11), either grant, deny, or grant with conditions, the emission permit. 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 application for the emission permit, the Preliminary Analysis of said application, and accompanying data concerning the proposed project and activity are available for inspection in the office of the Clerk and Recorder of Weld County, Colorado during regular business hours of said office, and also may be inspected at the office of the Air Pollution Control Division, Colorado Department of Health, 4300 Cherry Creek Drive South, Building B, 1st Floor, Denver, Colorado. # # # AIR POLLUTION CONTROL DIVISION PRELIMINARY ANALYSIS PERMIT NUMBER: 94WE494-2P DATE: October 5, 1994 APPLICANT: Weld County (Mining Division) REVIEW ENGINEER: Sunday A. Fadeyi CONTROL ENGINEER: Dennis M. Myers, P.E. PROJECT DESCRIPTION Gravel crushing equipment operation. SUMMARY OF EMISSIONS in Tons/Year Pollutant Uncontrolled Emissions Controlled Emissions Total Suspended Particulates 31.73 8.06 Particulate Matter less than 10 microns IPM„) 3.87 1.10 AMBIENT IMPACT ANALYSIS in micrograms/cubic meter (uo/m2} Pollutant Source Contribution Background Concentration Standard Area Status PM„ 124-hr.) 8.70 63.70 150.0 attainment SOURCE CLASSIFICATION Portable synthetic minor source currently in an attainment area(may be relocated in a non-attainment area in Colorado State). Particulate emissions from crusher is to be controlled by moist to wet material. Water sprays shall be used as necessary to control particulate emissions.The Division has determined that the control constitutes Reasonably Available Control Technology (RACT) for this source. The Division has determined that this source will meet all applicable standards and requirements. This source is considered a synthetic minor source for operating permits since on an uncontrolled basis, the source's Potential To Emit (PTE) exceeds 100 tons per year. With the benefit of control measures ( i.e. watering) and a limit on annual production, actual controlled emissions are less than the major source level of 100 tons per year. In order for a synthetic minor to be considered federally enforceable, the permit application is required to go through the public comment process.
