The Missouri Emissions Inventory System (MoEIS) is an online system for data entry. It allows facilities to submit emissions data electronically to fulfill reporting requirements. Facilities need a user ID and password to access the online system. If you already have a user ID and password and want to begin reporting emissions data, click on the MoEIS icon below to log in.
