EPC Reclamation Process
Ebensburg Power Company
• Consume about 500,000 tons coal refuse/yearsince initial operation – 10,700,000 tons
• Utilize about 480,000 tons ash/year for beneficial use
• Neutralize about 15,000,000 lb/year of sulfuric acid with beneficial use ash – since initial operation about 250,000,000 lbs
• Remove about 46,000,000 lbs/year of sulfuric acid away from PA waterways - since initial operation about 1,000,000,000 lbs
