For brownfield cleanup, it increases credits to 80% of remediation costs (or $12 million) in disadvantaged areas, and 60% (or $8 million) for other projects. The bill also creates new eligibility for facade rehabilitation projects and modifies application requirements to better target economic development in underserved communities.
