Plain-language change summary

The new version of HB 2428 includes additional provisions that clarify the role of counties in issuing permits for emission reduction credits. Specifically, it establishes that participating in the emission reduction credit program is voluntary for applicants, but if participation becomes mandatory in the future, counties will not be able to issue new credits. These changes are important because they give counties more flexibility while also ensuring that participation in the program is not forced unless required by law, potentially leading to more local control over environmental permitting.
