Emissions Inventory System

Starting with the reporting of emissions for Calendar Year 2021, the District’s Emission Inventory System (EIS) must be used to enter emission inventory data as described in Rule 19.3. EIS allows facilities to upload Emission Inventory Request Forms, review data requests, input data for each calendar year and view the resulting inventory online after District approval. 

EIS Portal for data year 2023 will be available for reporting starting February 5, 2024.

All emission inventories requested for data year 2023 have a due date will be April 5, 2024, with extensions allowed to May 1, 2024.

EIS Registration

All users will need to register with the EIS portal. If you are a Responsible Official (RO) for a facility but did not previously have an account on EIS, a registration email will be sent to your email address. The registration email will contain a link to complete the registration process, once the registration process is complete, you will be able to access the EIS Portal and use the tool to upload/submit your electronic emissions inventory report. If you are an agent, registering to assist in the reporting process, an email will be issued to the facility RO(s) notifying them of your pending request.
