Common Question

Is D058 needed if existing Class II tanks are reassigned for Class Ib fluids?

Archive Findings

Yes, if the facility will receive Class Ib oilfield waste. Historical records indicate that a Class II Directive 056 facility needs an oilfield waste management approval before receiving Class Ib fluids.

The issue was not whether the tank was physically new. The issue was the tank function and the waste stream it would receive.

Engineering Insight

Treat reassigned equipment as a regulatory change. Identify the exact tanks, pumps, truck-in points, and flow paths dedicated to Class Ib waste before preparing the D058 filing.

Current Guidance

Use Directive 058 and Manual 034 for the D058 activity or component. Check Directive 056 and Manual 012 if the existing licensed facility also needs amendment.
