To comply with the California Code of Regulations (CCR), a Hazardous Waste Tank Assessment must meet the requirements of 22 CCR §66265.190-200. Some of the key aspects of a Hazardous Waste Tank Assessment are:
A commonly overlooked requirement of the regulation can be found in section 66265.192 (a)(B)(5)(B) of the CCR, and states, “tank systems will be anchored to prevent flotation or dislodgement where the tank system is placed in a saturated zone or is located within a seismic fault zone.” With the abundance of fault zones spread throughout southern California, it is critical to ensure your hazardous waste containing tanks are properly secured to the ground to prevent a release caused by seismic activity.
A Seismic Evaluation should be performed by a qualified professional on all hazardous waste containing tanks to examine the tank’s dimensions, contents, anchorage, and geographical location. The ultimate objective of a Seismic Evaluation is to prevent a release of harmful fluids that could have negative impacts on individuals and the environment. This is done is by determining whether the existing tank anchorage is sufficient to secure the tank during a seismic event.
The need to seismically evaluate a tanks anchorage is commonly overlooked by both tank owners and qualified assessors alike. However, Certified Unified Program Agency (CUPA) inspectors will reject a Hazardous Waste Tank Assessment that does not contain a Seismic Evaluation accompanied by the corresponding engineering calculations used in the evaluation.
