Emissions Inventory Training

The Oklahoma Air Pollution Control Rules direct that annual emission inventories be submitted through DEQ’s approved electronic reporting system: SLEIS (State and Local Emission Inventory System). SLEIS is a web-based application that allows facilities to compile and submit point source emissions inventory data and inventory amendments

Three introductory training videos have been created to assist SLEIS users in the steps necessary to register for a SLEIS account and how to navigate through and use SLEIS to create an annual emissions inventory.

• ▶ SLEIS User Registration, Account Management & Report Preparation
• ▶ SLEIS User Interface
• ▶ SLEIS Template Use and Bulk Operations

The current version of SLEIS (3.3.0) includes enhancements described in the guidance and videos below.

• 2024 Emissions Reporting Updates and Guidance (pdf)
• ▶ SLEIS Enhancements: Changes for 2024 (and future years) Reporting
• ▶ SLEIS Enhancements: Cloning

Subchapter 5 of OAC 252:100 directly governs the submission of Emissions Inventories. For any question or in any situation, the Air Quality Rules always apply.
