UPDATED 12.28.2017 The ANPRM has been published in the Federal Register and is available here. Comments are due February 26, 2018.
EPA recently issued an advanced notice of proposed rulemaking (ANPRM) seeking information as it considers proposing emission guidelines to limit greenhouse gas emissions from existing electric utility generating units—that is, a rule to replace the Clean Power Plan. (The repeal of the CPP is underway, with EPA accepting comments through January 16, 2018.)
The ANPRM solicits comments on substantive issues that would be at the core of any new rule developed. For example, EPA asks about the relative roles and responsibilities of states and EPA, as well as how to define the Best System of Emission Reduction and what sources would be covered by the rule. EPA says that it welcomes comments on all related topics, although it asks that comments related to the repeal of the CPP be submitted in the separate docket.
Comments on the ANPRM will be due 60 days after it is published in the Federal Register.
