Effective October 20, 2003, NJAC 7-18, "Regulations Governing the Certification of Laboratories and Environmental Measurements," was modified to include oversight of air pollution samples. NJAC 7:18-2.2 states, "No laboratory other than a certified laboratory shall analyze samples for the purpose of establishing compliance with any regulatory program." The regulation provides for a phase-in period for air pollution samples, provided that the laboratory submits an administratively complete application within 180 days of the regulation effective date (which would work out to April 17, 2004). The laboratory would then be granted a temporary approval, good for one year, to allow for them to complete the certification process. If the laboratory fails to meet these timelines, the phase-in period is forfeited (NJAC 7:18-2.6(c)). For additional details on this regulation and the certification process, please refer to the regulation, which can be found on the Office of Quality Assurance web site. For questions regarding this regulation, please contact the DEP's Office of Quality Assurance at (609) 292-3950.
