inspections twice a year by either an EI V, work leader, team leader, or section manager to assess and evaluate processes and adherence to procedures. Corrective actions needed are discussed at the time of inspection and verification. Implementation of corrective actions occurs at the next accompanied inspection. This is documented in the investigators personnel file.

All modifications to methods must be listed on the Case-Narrative Sheet and be written in the laboratory’s standard operating procedures (SOP) if this is a routine procedure or whether a modification was necessary at the time of sample preparation and analysis in order to demonstrate compliance. A list of potentially acceptable modifications that are allowed for meeting RCRA compliance according to the U.S. EPA and TCEQ is presented here.
