Modifies provisions relating to a renewable natural gas program

This bill modifies Missouri's renewable natural gas program to allow gas corporations to voluntarily offer these services to customers. It requires the state Public Service Commission to create rules by July 2025 that define how companies can report their progress, submit project plans, and recover the costs of building necessary infrastructure. The legislation sets specific limits on how much a gas company can invest in these projects based on the size of its customer base and mandates that the commission review smaller project filings within 90 days. Additionally, the bill establishes a requirement for an annual report to lawmakers detailing the number of approved projects, the volume of gas produced, and the associated economic and environmental impacts.
