Annual Emissions Inventory Reports
MCAQD enables emissions reporting in January of each year, and email notifications are sent to the contacts for facilities that are required to submit an emissions inventory. All emissions inventory reports must be completed using the AQD Online Portal. Paper forms will not be accepted.
Before creating an emissions inventory, thoroughly review the EI instructions and help sheets and attend an emissions inventory workshop to learn about the AQD Online Portal and requirements for the current reporting period.
Due Dates
The 2022 annual emissions inventory reports were due on Sunday, April 30, 2023 at 11:59 p.m.
