Natural Streams Foundation Inc.

Natural Streams Foundation Inc., a nonprofit tax-exempt organization based in Sewickley, Pennsylvania, works as a sub-recipient on federal environmental remediation grants issued by the Department of the Interior's Office of Surface Mining Reclamation and Enforcement, administered through the Pennsylvania Department of Environmental Protection.

Natural Streams operates exclusively as a sub-recipient; the source does not document any prime grant or contract awards. All four awards in the source record are federal grant sub-awards, issued in two tranches: two sub-awards dated April 4, 2024, and two dated January 16, 2026. The organization has worked with a single federal customer — OSMRE — across the full portfolio, with all grants flowing through PA DEP as the prime recipient. Combined obligated dollars across these four awards total $24.1 million.

The capability portfolio centers on abandoned mine land (AML) reclamation and coal refuse remediation in southwestern Pennsylvania. Representative work includes the Marianna Project (multiple sub-awards, April 2024), which combines ecological restoration with economic development by reclaiming a Priority 2 AML site in West Bethlehem Township, repurposing the site as public athletic fields, and supporting potential renewable energy development and union coal mining jobs in the region. Two additional sub-awards dated January 16, 2026, address restoration at the Commodore No. 1 Mine site (addressing an approximate 1,770-foot-long, 65-foot-high refuse pile) and engineering and permitting work at the Marianna 58 site, where an estimated 1,260,000 cubic yards of refuse requires potential removal and site reclamation. Natural Streams' grant work operates at the intersection of environmental remediation, engineering permitting, and community economic development in legacy coal regions.
