**Per Memorandum of Understanding Between the South Coast Air Quality Management District and Ontario International Airport Regarding Ontario International Airport’s Air Quality Improvement Plan (December 2019), ONT must submit an initial annual GSE report to South Coast AQMD by June 1, 2021. To prepare this report, ONT may require owners and operators of GSE to submit data. However, no mention was made regarding such a submittal in the bi-annual progress report from June 2020, and the December 2020 progress report has not yet been made publicly available.
