Project Description

Geologic Hazard (Active Faulting and Sinkhole) StudiesA Zephyr professional geoscientist performed an active fault study within the Gulf Coast Region of Texas to satisfy the siting criteria of a RCRA Part B Permit Application. This study was accomplished by “desktop” study and field reconnaissance. The “desktop” study included the review of published studies documenting the locations of known and suspected surface faults in the area; analyzing historic topographic maps for geomorphic features related to surface faults, and photo interpretation of historical aerial photographs for tonal anomalies potentially associated with active surface faults. A field reconnaissance of the site and surrounding area was performed by a registered professional geoscientist to locate physical evidence of surface fault activity. Surficial evidence related to active surface faulting includes foundation and pavement structural distress, abrupt topographic drops, and the presence of aligned “sag” ponds. The evidence gathered for this active surface fault study indicated that a surface fault most likely enters the site, but terminates within the property. The findings of this fault study were used to define a buffer zone in which facility structures will not be built.
