This funding opportunity provides funding for States and Tribes to develop inventories of brownfield sites, prioritize sites, conduct community involvement activities, conduct planning, conduct site assessments, develop site-specific cleanup plans, and develop reuse plans related to brownfield sites. Applicants may request funding up to $2,000,000 to address sites contaminated by hazardous substances (i.e., sites with potential contamination of hazardous substances, pollutants, or contaminants) and/or petroleum (i.e., sites with potential petroleum contamination) throughout their jurisdiction. Recipients will be required to assess sites (a minimum of 10) throughout their geographic boundary(ies). All sites selected during the period of performance (i.e., sites that were not identified in the original workplan) must be located in an underserved and/or disadvantaged community.
