Harris County has ceased continuous air monitoring for the Intercontinental Terminals Company (ITC) Deer Park incident since no benzene level readings indicating a threat to public health have been found outside of the areas where public access has been blocked* since late March. This website is no longer being updated as of April 12, 2019. Harris County Commissioners Court has moved to explore a permanent approach to providing ongoing air monitoring information to the public, with an initial report expected back to Commissioners Court by May 24, 2019.

EPA and TCEQ are each still monitoring for benzene and other volatile organic compounds. Harris County is tracking the information collected on these agencies’ websites, which can be found here:

As a reminder, to report complaints regarding odor from the ITC incident or general air, water, or solid waste pollution complaints, please contact Harris County Pollution Control Services at (713) 920-2831.

* Public access has been blocked in the industrial complex and in the chemical spill area at Tucker’s Bayou.
