Comment from Summit Sustainable Ingredients, LLC (d/b/a "Amber Wave")

Summary: Amber Wave, a major producer of food ingredients and low-carbon fuels, supports the proposed Section 45Z regulations but requests specific clarifications and improvements. The company argues for expedited DOE guidance on the PER petition process, retroactive credit claims for early 2025 production, and the establishment of a "safe harbor" for facilities with existing international certifications to ensure operational certainty and economic viability.
