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 Jan 1, 2022, the Wyoming SERC is requiring an “Emergency Plan” for facilities meeting the EPCRA Section 302 criteria, please see the New Wyoming Requirement topic in the Help & Support below.
