ITRC State Concurrence Process

What is the ITRC state concurrence process?
State concurrence is the formal review and documented acceptance of the willingness to use/test ITRC Technical and Regulatory Guidance Documents. The Point of Contact (POC) in each ITRC state is responsible for having the appropriate personnel in their state agency review the ITRC Technical and Regulatory Guidance Documents and to provide their state's level of concurrence on each document. The POC will then send a letter to the ITRC State Engagement Coordinator indicating their state's level of concurrence on the specific document. This information is maintained and updated in a concurrence matrix. The intent is to provide concurrence information to document users via the website.

Why is the concurrence process important?
The concurrence process serves as a formal mechanism to gain state commitment to use the ITRC products and services. In addition, concurrence on ITRC Technical and Regulatory Guidance Documents provides predictability for parties wanting to use an innovative technology in an ITRC state.

Who should sign a concurrence letter?
This is up to each state on an individual basis depending who has been designated in their state to serve in that role. The preference is to have the highest-level management personnel in the state's environmental agency sign off on a letter of concurrence. We have received concurrence letter from a variety of management levels (e.g., agency directors, program managers).

Where should state concurrence letters be sent?
Please send state concurrence letters on ITRC technical and regulatory guidance to the ITRC State Engagement Coordinator:
Mr. Paul Hadley
California Dept. of Toxic Substances Control
P.O. Box 806
Sacramento, CA 95812-0806
P 916-324-3823 / F 916-327-4494
phadley@dtsc.ca.gov

Which documents is the ITRC requesting formal concurrence on and what is the current status on the document concurrence?
The ITRC is requesting formal concurrence on all ITRC Technical and Regulatory Guidance Documents produced by ITRC technical teams. A list of these documents is attached and includes the current status by state and the level of state concurrence submitted.

What are the levels of concurrence?

A = We concur. We agree that the requirements/guidelines are appropriate and commit to using them to the maximum extent feasible.
B = We agree that the requirements/guidelines are appropriate; however, we cannot commit to level A concurrence for this reason: (state response)
C = We do not concur with the requirements/guidelines for this reason: (state response)
