Title:WHAT CONSTITUTES A CONTAINED GASEOUS MATERIAL WASTEWATER TREATMENT SLUDGES THAT ARE PROCESSED IN ANAEROBIC DIGESTERS TO PRODUCE BIOGAS
RCRA Online Number:14830
Date:02/15/2012
To:Hornback
From:Rudzinski
Organization of Recipient:National Association of Clean Water Agencies
Description: EPA considers the anaerobic digestion of wastewater treatment sludge to produce biogas as meeting the definition of of processing pursuant to 40 CFR 241.2. The biogas is primarily composed of methane and CO2 and has been used to heat the digesters and, at many treatment facilities, to generate power. The biogas can be collected and burned as a fuel to produce electricity using onsite power generation equipment. Additionally, heat can be recovered from the power generation units. EPA has not changed the position of what constitutes a "contained gaseous material" for defining solid waste as it relates to biogas generated by the anaerobic digestion of wastewater treatment sludge and used for energy recovery. Therefore, biogas from anaerobic digestion is considered a commodity fuel processed from waste materials and not a traditional fuel.
