Proposed Rule, Federal Register 06May98
F-98-CUOP-FFFFF Williston Basin is a natural gas transportation and storage company operating approximately 3,000 miles of underground natural gas transmission pipeline in Montana, North Dakota, South Dakota, and Wyoming. Williston Basin operates pipeline booster stations in which engines driving compressors, compress the natural gas and discharges it at higher pressures down the pipeline. Williston Basin generates used oil from its compressor engines during periodic oil changes. This used oil is "on-spec" and always has been on-spec - very low in contaminants. Williston Basin is pleased to provide the following comment/clarification. Currently, EPA is making the following clarification:
"... the initial marketer of used oil that meets the
used oil fuel specification need only keep a record of a
shipment of used oil to the facility to which the
initial marketer delivers the used oil." Would you please clarify if Subpart H-"Standards for Used Oil Transporters and Transfer Facilities" is applicable to those processor and re-refiners who transport their on-spec oil or fuel product. (We do not process/re-refine!) We all know that used oil that is to be burned for energy recovery and that meets the specification provided under 40CFR279.11 is essentially exempt from the regulations. So how about those entities that manage the on-spec used oil. Are we, as a generator consolidating on-spec used oil from satellite locations to a central location regulated as a transporter and subject to the Standards for Used Oil Transporter and Transfer Facilities? Their remains ambiguity in the regulations. You can see this ambiguity if you review the "Notification of Regulated Waste Activity" booklets published by the U.S. EPA, dated 30NOV93.
"Persons who transport, process, re-refine, market or
burn off-spec used oil for energy recovery are required
to notify..." (emphasis added) Call if you have questions. Thank you.
