Document Description
The California Department of Toxic Substances Control (DTSC), pursuant to authority granted under California Code of Regulations, Title 22, Division 4.5, Chapter 20, approved a Class 2 Permit Modification (Permit Modification) to modify the groundwater monitoring program for the Clean Harbors Buttonwillow, LLC (CH Buttonwillow) facility located at 2500 West Lokern Road in Buttonwillow, California 93206. Declining water levels, due to drought conditions and regional decreases of groundwater levels, has resulted in existing groundwater monitoring wells being unable to yield any representative groundwater samples. The Permit Modification will authorize the modification of the groundwater monitoring program to change the status of one monitoring well (MW) 153-RL to a piezometer and install one replacement well (MW-153RRL). Additionally, groundwater monitoring wells will be decommissioned if they no longer yield representative groundwater samples after 15 years. The Permit Modification does not include any other changes in operations, additional construction, or ground disturbing activities.
