Title:SAFE DELIVERY SYSTEMS (SDS) GAS CYLINDERS
RCRA Online Number:14762
Date:02/13/2007
To:Patterson
From:Hale
Organization of Recipient:Beveridge and Diamond
Description: SDS cylinders contain a carbon-based medium which operates as a “molecular sieve” in which the gas is adsorbed and trapped within the interstitial spaces. As a result, the gas is stored under sub-atmospheric pressure, which avoids safety concerns with high-pressure containment and also allows a greater volume of gas to be stored in the container. The storage and delivery cylinders are containers holding unused CCPs, rather than spent materials, and therefore are not subject to regulation under 40 CFR 261.2(c)(3) as spent materials. Containers that held unused CCPs and any residues generated from CCP recovery must undergo a new hazardous waste determination after the cylinders are emptied. Abandoned CCPs are solid wastes (40 CFR 261.2(i)), and if hazardous, are hazardous wastes.
