EA-1449: Final Environmental Assessment

Commercial Demonstration of the Manufactured Aggregate Processing Technology Utilizing Spray Dryer Ash, King George County, Virginia

The proposed action is for the U.S. Department of Energy (DOE) to provide cost- shared financial support to Universal Aggregates, LLC, for the design, construction, and operation of a lightweight aggregate manufacturing plant at the Mirant-Birchwood Power Plant Facility (Mirant-Birchwood Facility) in King George County, Virginia. DOE would provide approximately 37% of the $19.6 million cost of the project (about $7.2 million), with the industrial participant providing the remainder of the cost. The project, which includes 15 months of operation and testing, would involve transforming 115,000 tons of spray dryer ash currently generated at the Mirant- Birchwood Facility into 167,000 tons of lightweight aggregate for use in the manufacture of lightweight masonry blocks or lightweight concrete. Based on the results of the demonstration, the funding provided by DOE would be repaid by the industrial participant if the project is successfully commercialized.
