NOTICES

Environmental Laboratory Accreditation Proficiency Test Study Requirements

[36 Pa.B. 8006]
[Saturday, December 30, 2006]

   In accordance with 25 Pa. Code § 252.501(a) (relating to proficiency test study requirements), the Department of Environmental Protection (Department) is providing the following tables which list the fields of accreditation (FOA) for which proficiency test (PT) studies are available. To obtain or maintain an FOA, the Department requires that an environmental laboratory successfully participate in PT studies when available. The following tables contain FOAs for which PT studies are available for nonpotable water, drinking water and solid and chemical materials.

   The following Fields of Proficiency Testing (FoPT) listing updates the previous listing published at 36 Pa.B. 1181 (March 11, 2006). The new FoPT tables become effective on January 1, 2007. Please note that FoPTs have been added, removed, and in some cases, rearranged into different subgroups since the previous publication of the tables. The added compounds are denoted with an asterisk beside them in the tables. Environmental laboratories seeking to maintain accreditation for a FOA that has been added to the tables by this notice must successfully complete a PT study for that analytes by January 1, 2008. Environmental laboratories seeking initial accreditation or laboratories seeking to add FOAs to their current Scope of Accreditation must successfully complete a PT study before accreditation is granted. Accredited environmental laboratories must successfully complete at least one PT study for each FOA, where available, once every 12 months to maintain accreditation. Additional information regarding the proficiency test study requirements is contained in 25 Pa. Code Chapter 252, Subchapter E (relating to environmental laboratory accreditation).

   Updates to the following lists will be published in the Pennsylvania Bulletin as revisions are made. Questions concerning this notice, including the lists of proficiency testing currently available, should be directed to Richard Sheibley, Department of Environmental Protection, Bureau of Laboratories, (717) 346-8215, rsheibley@state. pa.us.
