Please read the "NOTICE" below published on EPA's Air Emission Measurement Center website:

"NOTICE: It has come to our attention that one of the two providers of audit samples has ceased manufacturing samples for the stationary source audit program. The general provisions to 40 CFR Parts 60 and 63 (see §60.8(g)(1) and §63.7(c)(2)(iii)(A)) require that the owner or operator obtain audit samples if the audit samples are "commercially available" and have defined "commercially available" as two or more independent accredited audit sample providers (AASP) to have blind audit samples available for purchase. Since there are no longer two providers, the requirement to obtain these audit samples is no longer in effect until such time as another independent AASP has audit samples available for purchase. When there are two or more AASP with audit samples available for purchase, we will update this webpage with the name or names of the providers and audit sample(s) available for purchase. At that time, this information must be listed on the EMC website for 60 days before audits are required again." Accordingly, the requirement to obtain Stationary Source Audit Samples (SSAS) for NJ stack tests is currently suspended until such time that SSAS are deemed "commercially available" again by EPA. With that said, audits ARE still available from the remaining SSAS Provider, and we STRONGLY encourage continued voluntary purchases of SSAS from the this Provider for NJ compliance tests, to protect both the facility's and public's interests in obtaining quality emissions data. Additionally, any SSAS that have already been purchased, and any that have been ordered prior to May 20, 2019 (the date that the second Provider stopped having SSAS available for sale), MUST still be analyzed as part of the applicable test program for which they were ordered. Should you have any questions, please contact Michael Klein of EMS at 609-984-3443.
