Draft Guidance

   DEP ID: 275-2101-009. Title: Waste Derived Liquid Fuels (WDLF). Description: The Department of Environmental Protection (Department) is proposing a revision to the technical guidance for the use of Waste Derived Liquid Fuels (WDLF). This proposed technical guidance document change, authorized under section 6.6(c) of the Air Pollution Control Act and 25 Pa. Code §§ 127.1 and 127.12(a)(5), will apply to owner/operator sources that switch from a virgin fuel to a WDLF. The technical guidance will also apply to a change from an existing WDLF to one of a different classification or to a change in the contaminant or physical property characteristics within a WDLF category that is substantially different than specified in a previously issued plan approval. The owners and operators of new and existing sources are required to obtain plan approvals under 25 Pa. Code Chapter 127.

   The objective of this technical guidance is to establish air quality permit review procedures for sources that use WDLF and to establish a method to classify WDLF for ease in permit review using minimum contaminant and physical property specifications. Waste oil fuel that does not exceed the specifications is termed ''on-specification waste oil fuel.'' Waste oil fuel that exceeds any specification level is termed ''off-specification waste oil fuel.'' The classification will be used in conjunction with the permit review requirements to identify the level of permit review required.

   The following changes will be considered to be modifications pursuant to 25 Pa. Code § 121.1:

   1.  A change from a virgin fuel to a waste derived liquid fuel or a virgin oil to which waste liquids or solids have been added or blended;

   2.  A change from a waste derived liquid fuel to one in a different classification; or,

   3.  A change in the contaminant or physical property characteristics within a waste derived liquid fuel category that is substantially different than specified in a previously filed plan approval application or occurring after July 1, 1972, at a previously unpermitted source. New sources as well as existing (pre-1972) or new (post-1972) modified air contamination sources are required to obtain 25 Pa. Code Chapter 127 plan approval.

   This revised technical guidance document contains updated classifications and definitions of waste derived and hazardous waste derived liquid fuels. In addition to defining the limits that classify waste derived liquid fuel as on-specification waste derived liquid fuel or off-specification waste derived liquid fuel, the requirements for toxic substances derived liquid fuels has been updated. Each applicant for a waste derived liquid fuel plan approval must submit, for each fuel supplier or waste stream, a completed supplemental form entitled Waste Derived Liquid Fuel, which will be used to determine the waste derived liquid fuel classification as defined in Section B of the technical guidance document (Addendum B).

   This technical guidance document also describes both general and specific permit review procedures, analytical and sampling reference techniques, total halogen screening, sample taking and retaining procedures, PCB/METALS/TX/Flash auditing procedures and WDLF content specifications. Written Comments: The Department invites written comments on the proposed change. Interested persons may submit written comments, suggestions or objections to Joseph White, Environmental Engineer Manager, Technical Support Section Chief, Division of Permits, Bureau of Air Quality, 12th Floor, Rachel Carson State Office Building, P. O. Box 8468, Harrisburg, PA 17105-8468. The Department will also consider written requests that a public hearing be held concerning this proposed technical guidance document change. Written public comments must be submitted to the Department by September 1, 2009. Comments received by facsimile will not be accepted. Contact: Interested parties are encouraged to obtain and review a complete copy of this proposed technical guidance document change by contacting Jeanette Van Skike, Division of Permits, Bureau of Air Quality, 12th Floor, Rachel Carson State Office Building, P. O. Box 8468, Harrisburg, PA 17105-8468, (717) 787-4325. TDD users may telephone the Department through the Pennsylvania AT&T Relay Service, (800) 654-5984. Internet users can access a copy of the proposed technical guidance document at (DEP Keyword: Air Permits) (look under ''Draft Guidance Documents''). Effective Date: Upon publication of notice as final in the Pennsylvania Bulletin
