Comment from Calgren and Pratt Energy

Summary: Calgren and Pratt Energy, domestic fuel producers, support the proposed regulations for the section 45Z clean fuel production credit as a good start toward clarifying eligibility and implementing the One Big Beautiful Bill Act. They request specific updates to the 45ZCF-GREET model, clarifications on qualified sales for related persons, and more precise definitions of "facility" boundaries to ensure compliance with prevailing wage and apprenticeship requirements.
