It should be noted that although exempted sources may not need air emission permits, they are still required to meet all <br />applicable standards and regulations of the Air Quality Control Commission, including: <br />Visible emissions shall not exceed 205yo opacity, and the odor requirements of Regulation No. 2. <br />A Revised Air Pollutant Emission Notice (APEN) shalt be filed: (Reference: Regulation No. 3, Part A, Section II.C.) <br />a. Annually whenever a significant increase in emissions occurs as follows: <br />For any criteria pollutant: <br />For sources emitting less than 100 tons per year, a change in actual emissions of five tons per year or <br />more, above the level reported on the last APEN submitted; or <br />For volatile organic compounds (VOC) and nitrogen oxide (NOx) sources in an ozone non -attainment area <br />emitting less than 100 tons of VOC or nitrogen oxide per year, a change in actual emissions of one ton per <br />year or more or five percent, whichever is greater, above the level reported on the last APEN submitted; <br />or <br />For sources emitting 100 tons per year or more of a criteria pollutant, a change in actual emissions of five <br />percent or 50 tons per year or more, whichever is less, above the level reported on the last APEN <br />submitted; or <br />For sources emitting any amount of lead, a change in actual emissions, above the level reported on the <br />last APEN submitted, of fifty (50) pounds of lead <br />For any non -criteria reportable pollutant: <br />If the emissions increase by 50% or five (5) tons per year, whichever is less, above the level reported on <br />the last APEN submitted to the Division. <br />b. Whenever there is a change in the owner or operator of any facility, process, or activity; or <br />C. Whenever new control equipment is installed, or whenever a different type of control equipment replaces <br />an existing type of control equipment; or <br />d. Whenever a permit limitation must be modified; or <br />e. No later than 30 days before the existing APEN expires. <br />The source operates this engine for readiness testing and emergencies only. The source maintains records <br />of hourly operation. Since beginning operation of the engine several years ago, the hour meter reads a total <br />of only 388 hours. This unit is propane fueled, and operates without visible emissions. The original <br />APEN/Permit application for this point was submitted on 3/18/2014 and does not expire until 2019. There <br />have been no process modifications or changes in emissions which would require a more recent submission. <br />The source is in compliance with all requirements of the APEN Required/Permit Exempt letter, and <br />applicable AQCC Regulations. <br />Note: Although APEN-required at a annual use rate of 500 hours/year, the actual operating hours of this <br />equipment place it far below APEN-reporting thresholds. Using the emissions factors associated with this <br />exemption letter, unless yearly hourly hours of operation begin to exceed 270 hours, the unit will remain <br />APEN exempt with CO emissions below 2 tpy. The source submitted a cancellation request for this point on <br />10/26/2015. <br />2015 Inspection Aff <br />0510015-INSP-2015 Page 34 of 37 <br />
