CK ENVIRONMENTAL is First in Region to Receive AETB Interim Accreditation

Canton, MA, April 8, 2009 – CK Environmental Inc. (CK) is the first firm in the region to receive Air Emissions Testing Body (AETB) interim accreditation from the Stack Testing Accreditation Council (STAC). After careful review of CK’s Quality System documentation and procedures, STAC determined that CK’s QA/QC practices are in conformance with ASTM D7036-04 “Standard Practice for the Competency of Air Emissions Testing Bodies.” This rigorous standard assesses the overall ability of a stack testing firm to deliver data of known and documented quality on a consistent basis regardless of the test method used. Utilizing the services of an accredited firm provides assurance to both clients and regulatory agencies that a stack testing firm is providing them with accurate reliable data. A current list of firms with interim accreditation is available at Final accreditation requires successful completion of a field audit. STAC is currently developing a protocol for use during field audits, thus no firms currently hold full accreditation.

In addition to routinely performing rigorous internal quality control procedures, Accredited Emissions Testing Bodies (AETB) commit to ensuring that all testing is performed only by qualified individuals. The qualifications of individuals are assessed by the Source Evaluation Society (SES). Qualified Source Testing Individual (QSTI) candidates must document field experience and pass a series of exams.

The goal of the SES QSTI exams and abilities assessment is to determine whether the candidate demonstrates knowledge and the ability to apply source testing methods and fundamental engineering and chemistry principles in a manner consistent with that of a field test team leader. In addition to thorough and practical knowledge of source testing methods, those principles include an understanding of elementary physical gas laws and chemistry, basics of safety and hazardous material handling, and primary theories of source testing (e.g., isokinetic and proportional sampling). The candidate is expected to exemplify and demonstrate professional and ethical conduct not only during the exam process but also in representing SES as a QSTI.
