For every Permit to Operate (PTO), facilities are required to submit an annual throughput form that identifies the level of production for that permitted process. The District has traditionally mailed these forms every January with a due date of March 31. This information is compiled by the District to quantify actual emissions from each of the permitted sources, and then the District develops an emissions inventory which is reported annually to the California Air Resources Board.

This year, the District is not mailing the 2022 Throughput Forms, they are being provided electronically. The forms have been emailed to each facility’s responsible contact, and are also available by clicking the link below.

Click the link INSTRUCTIONS for guidance on completing the Throughput Forms, and to locate your facility’s forms click FIND YOUR FORM. The forms are due by March 31, 2023. Please note electronic or digital signatures are accepted.

Permit holders who fail to submit the requested information may have their PTOs revoked. Operating without a permit is a violation of District rules and state law, and involves serious penalties.
