TNI Environmental Lab

ANAB offers accreditation to The NELAC Institute (TNI) Volume 1: Management and Technical Requirements for Laboratories Performing Environmental Analysis.

Environmental laboratories can now become accredited to multiple standards through one accreditation process. In addition to the TNI 2009 standard, the laboratory will be accredited to ISO/IEC 17025 and has the additional options for accreditation to the Department of Defense (DoD) Environmental Laboratory Accreditation Program (ELAP) and the EPA National Lead Laboratory Accreditation Program (NLLAP).

The coordinated approach to environmental programs gives ANAB accredited laboratories mechanisms for greater responsiveness to laboratories' changing needs. ANAB can adapt to any scope required by the laboratory and are not limited to only accredit to analytes regulated by state entities through regulation. ANAB has available means to provide scope expansions to laboratories within reasonable timeframes, cooperation that is necessary to allow for adequate response to short turn-around bids and proposals.

ANAB is currently accepting new applications for accreditation of laboratories that intend to test to the TNI requirements. ANAB is working with existing accredited laboratories to add compliance with these requirements to their existing scopes of accreditation.

ANAB accepts applications from laboratories interested in accreditation to the TNI standard.

TNI Environmental Proficiency Test Provider

In addition to offering a traditional ISO/IEC 17043 PT provider accreditation program, ACLASS is recognized by TNI as an approved accreditation body for PT providers conducting PT studies for the evaluation of environmental testing laboratories. This program is called the National Environmental Proficiency Testing Program (NEPTP).

NEPTP relies on consensus standards representing the best professional practices in the industry to establish requirements for this program. The TNI Standard for PT Providers, Volume 3, is modeled after ISO/IEC Guide 43, General Requirements for the Competence of Testing and Calibration Laboratories. TNI Standard Volume 4 is requirements for a proficiency test provider accreditor. The standard is based on ISO/IEC 17011:2004, Conformity Assessment - General Requirements for Accreditation Bodies Accrediting Conformity Assessment Bodies.

The following shall apply, as appropriate, and ANAB will ensure that:

  • The PT provider's quality management system meets the requirements of ISO 9001 for the design, production, testing, and distribution of PT samples and the evaluation of PT results.
  • The PT provider's manufacturing system meets the requirements of ISO Guide 34, General Requirements for the Competence of Reference Material Producers.
  • The testing facilities used to support the verification, homogeneity, and stability testing required in the standard meet the requirements of ISO 17025, General Requirements for the Competence of Testing and Calibration Laboratories).

TNI Stationary Source Audit Sample Program

ANAB is a recognized accrediting organization for TNI's Stationary Source Audit Sample (SSAS) Program. Stationary source testing is a field of environmental monitoring that measures the emissions of air pollutants from stationary sources, such as smoke stacks or factories. The SSAS Program was established for the environmental monitoring industry that measures emissions of pollutants from such sources.

Previously, the U.S. EPA's Office of Air and Radiation administered a Stationary Souce Audit Program that provided free audit samples used by state and local agencies to guage the accuracy and effectiveness of SSAS testing. The increasing need for audit samples and the availability of private sector organizations capable of providing them led EPA to discontinue supplying these samples and instead rely on TNI's SSAS Program.

On September 13, 2010, the U.S. Environmental Protection Agency (EPA) issued the final rule to restructure the stationary source audit program. This program provides criteria to assure that the analyst and field-testing personnel are capable of conducting emissions testing for compliance with the Clean Air Act requirements. Audit samples must be analyzed along with the samples collected while testing for regulatory compliance. This analysis helps the regulatory agency determine the validity of compliance test results.

The changes finalized in this rule allow accredited providers to supply the audit samples and require sources to obtain and use audit samples obtained from the accredited providers instead of EPA, as was the former practice. In addition, this action moves the requirements for audits from EPA's rules laying out individual emissions test methodologies to generalized requirements in the general provisions of the Clean Air Act. EPA has approved the TNI SSAS Program to provide accredited audit samples based on three documents.

The TNI SSAS Program includes the following elements:

  • Production and supply of stationary source audit samples that challenge the critical components of each source test procedure, from sample collection to sample analysis
  • Production and supply of audit samples, the matrices of which to the extent possible resemble the matrices that  participants routinely analyze
  • Yielding of audit sample data that are technically defensible on the basis of the type and quality of the audit samples provided
  • Preparation of audit samples that pose equivalent difficulty and challenge, regardless of the manner in which they are designed and manufactured by the SSAS providers
  • Establishment of requirements for facilities, regulatory agencies, stationary source testers, laboratories, and providers participating in the SSAS Program

ANAB is recognized as an accrediting organization for TNI's Stationary Source Audit Sample (SSAS) Program. Stationary source testing is a field of environmental monitoring that measures the emissions of air pollutants from stationary sources, such as smoke stacks or factories. The SSAS Program was established for the environmental monitoring industry that measures emissions of pollutants from such sources.

ANAB's assessment criteria for SSAS providers are based on TNI General Requirements for Stationary Source Sample Providers, Volume 1, Module 1(2009-Rev 0.2), available at http://nelac-institute.org/ssas/.

ANAB accepts applications from SSAS providers seeking accreditation and offers scope expansions to ANAB-accredited TNI proficiency testing providers that offer stationary source audit samples.
