EPA OTAQ updates BABA implementation procedures (memo + FAQs) for OTAQ financial assistance programs

EPA OTAQ issued an updated memorandum and FAQ-style “BABA Implementation Procedures” for OTAQ-administered federal financial assistance programs (including DERA, Clean School Bus, Clean Ports, and Clean Heavy-Duty Vehicles). The update provides operational guidance on BABA applicability, compliance responsibilities, documentation/certification expectations, and waiver pathways, including newly added/updated Q&As (e.g., de minimis waiver cost calculation clarifications for certain mobile equipment and fueling infrastructure project scenarios). Compliance teams supporting EPA OTAQ-funded projects should align procurement classification (iron/steel, manufactured products, construction materials), contracting language, record retention, and waiver documentation to the updated procedures.
