Welcome to the Wyoming Tier II Portal

The Wyoming SERC has provided this online portal in order to upload electronic Tier II Submit files along with accompanying documents. The SERC does NOT need a paper copy of the entire report if it is submitted in electronic format. Fill in the form below with the submitter's information and click "Submit". Once completed, you will be prompted to upload your Tier II Submit (.T2S) file. Beginning in 2022, the Wyoming SERC requires facilities meeting the EPCRA Section 302 criteria to submit an ‘Facility Emergency Plan’ attached to their annual Tier II file submission. Please see the ‘302 Emergency Plan Info’ topic in the Help & Support below for more information.
