Amends the Environmental Protection Act. Repeals the definition of "food scrap"; adds definitions for "anaerobic digestion", "biogas", "digestate", "food waste", "organic material", and "organic waste"; and updates the definitions of "compost" and "composting". In provisions regarding pollution control facilities, includes a new exemption for portions of sites or facilities used for composting or anaerobic digestion of organic waste that meet specified siting, setback, floodplain, and operational requirements. In provisions regarding prohibited acts, establishes permitting requirements for organic waste composting operations and organic waste anaerobic digesters, and creates exemptions for small-scale and certain farm-based composting operations that meet volume limits, setback distances, and other environmental safeguards. Provides that anaerobic digesters using only non-waste feedstock are exempt from solid waste permitting and clarifies that digested material returned to the economic mainstream is not regulated as waste. Authorizes the Environmental Protection Agency to recommend, and the Pollution Control Board to adopt, performance standards for organic waste compost facilities and testing procedures for end-product compost, and requires a Technical Advisory Committee with balanced stakeholder representation. Specifies that standards apply to compost offered for sale or use and exempts on-site residential composting. Makes conforming changes throughout to integrate new definitions and regulatory requirements.
