General Lab Criteria Inspection Forms

Ohio EPA Division of Surface Water is now including basic inspections of wastewater treatment plant laboratories with their Compliance Evaluation Inspections (CEIs). These are separate from the detailed lab audits conducted by Ohio EPA Division of Environmental Services and are intended to be an overview of laboratory practices.

The intent is to identify "red flag" issues. These are problems with laboratory practices which may call into question the reliability and accuracy of data generated.

The lab inspection process (General Lab criteria or GLC) uses a "broad strokes" approach and does not require inspectors to review details of analytical procedures. The intent is to help wastewater labs generate defensible data. Deficiencies discovered in initial inspections will not generally be treated as violations.
