Draft Technical Guidance--Substantive Revision
[28 Pa.B. 6236] DEP ID: 274-0300-002 Title: Source Testing Manual (Revision 3)
Description: This manual is intended as guidance to clarify the procedures for conducting testing and reporting the results. It is not a regulatory document. The Source Testing Manual was first released in January 1983. In June 1995, minor revisions were made. Revision 3 is an overhaul encompassing major changes.
Major changes include: (1) VOC testing and reporting, (2) more quality assurance (QA), and (3) inclusion of additional test methods. Changes to deal with VOC testing and reporting are (1) guidance for expressing VOC results on an ''as emitted'' basis, (2) guidance on accounting for formaldehyde when determining total VOC emissions, and (3) improved QA. The improved QA procedures include (1) more audit samples, (2) more representative system bias checks, (3) determination of collection and recovery efficiencies of sampling trains, and (4) EPA Protocol 1 calibration gases (±1%). The back-half analysis for particulate is no longer required allowing for combined sampling trains.
Potentially Affected Parties: (1) wood product industry, (2) wood-fired sources, (3) sources emitting chlorinated or oxygenated VOCs (for example, chemical manufacturers or bakeries), and (4) inexperienced or ''poor quality'' testing teams.
Extended Deadline for Submittal of Comments: January 6, 1999.
Anticipated Effective Date: February 8, 1999 Contact: Rick Szekeres at (717) 772-3938.
