WLA Consulting, Inc. has worked with this facility for over fifteen years. WLA staff created an emission tracking system (ETS) to demonstrate compliance with permit conditions and limits. WLA assists Duncan Aviation with tracking and calculating monthly air emissions. As required by the Lincoln Lancaster Health Department (LLCHD), Duncan Aviation must keep air emission calculations on a monthly and rolling twelve-month total basis for all air emissions. Each month Duncan Aviation provides WLA with production data from the facility. Using these quantities, WLA completes the necessary air emission calculations and documentation. This information has been reviewed and accepted by the Lincoln Lancaster Health Department during multiple air quality inspections. WLA also provides support to Duncan Aviation with their
annual air emissions inventory submittal to the LLCHD. Using the recorded data from the air emissions tracking system developed by WLA, the inventory is easily completed.
