ELAP - Regulations

On May 5th, 2020, the State Water Board adopted the proposed ELAP regulations. The page below is available for historical information on the regulation development process. Information about ELAP’s compliance assistance campaign, Roadmap to ELAP Accreditation, can be found at: https://www.waterboards.ca.gov/drinking_water/certlic/labs/roadmap_to_elap_accreditation.html


At its May 5, 2020, public meeting, the State Water Resources Control Board (State Water Board) adopted regulations amending the requirements and standards for accreditation of environmental testing laboratories in California. Consistent with California Health and Safety Code, sections 100829 and 100830, the regulations bolster the effectiveness of the State Water Board’s Environmental Laboratory Accreditation Program (ELAP) through modification of existing program operations, elimination of outdated requirements and replacement of state-created accreditation standards with the national consensus-based 2016 TNI Standard, Volume 1: Management and Technical Requirements for Laboratories Performing Environmental Analysis (2016 TNI Standard), with two California-specific exceptions.

Implementation Assistance

The State Water Board is proposing to assist laboratories in making the transition to the 2016 TNI Standard by providing tools, training, and a three-year implementation period for many requirements.

  • TNI Documentation Workshops
    We envision a one-day workshop focused on document development that is open to all laboratories. It will be held throughout the state and will include in-class work with a consultant to develop documentation required by the TNI Standard. Laboratories will receive templates and tools as part of this workshop.
  • Support for TNI Mentor Groups
    In 2016, ELAP conceptualized a TNI Mentorship Initiative to assist laboratories in the implementation of the TNI Standard. In December 2018, the American Council of Independent Laboratories (ACIL) formed a TNI Mentor Group to assist laboratories in California to implement Quality Management System requirements in the 2016 TNI Standard. The participating laboratories ranged from small, remotely located municipal laboratories to small commercial or public health laboratories. There are currently seven early adopter laboratories who volunteered to participate as a Mentee to advance their laboratory operations and management practices and provide data of known, documented and defensible quality. The information from these early adopter laboratories will help inform ELAP on what specific tools, templates, and trainings California laboratories need to successfully implement the 2016 TNI Standard.

    ELAP is offering support to any laboratory mentor groups that have formed to assist each other with implementation of the TNI Standard. Contact us at elapca@waterboards.ca.gov to see how we can assist you.

  • TNI Membership
    ELAP has negotiated a free 6-month membership to TNI, for its laboratories, which includes member rates on documents and trainings. This membership can be requested until the time the Regulations package is adopted by the State Water Board. Email TNI's Executive Administrator, Suzanne Rachmaninoff, at suzanne.rachmaninoff@nelac-institute.org to request membership. In addition to receiving discounted rates on TNI implementation resources, members also have the benefit of participating in the formal consensus process. ELAP encourages laboratories to take an active role in this process and represent California at the national level.
