Turpentine Storage

Q. Is turpentine covered under Spill Prevention, Control, and Countermeasure (SPCC) and what are the spill containment requirements for AST of turpentine?

A. Turpentine is a nonpetroleum oil, and its storage is regulated under SPCC.

If your facility meets the SPCC regulatory threshold (aggregate storage capacity of more than 1,320 gallons aboveground), it must also meet SPCC secondary containment requirements. The entire containment system, including walls and floor, must be capable of containing oil and must be constructed so that any discharge from a tank will not escape the containment system before cleanup occurs. In determining the method, design, and capacity for secondary containment, an owner or operator must address only the typical failure mode and the most likely quantity of oil that would be discharged. Secondary containment may be either active or passive.

At a minimum, one of the following prevention systems or its equivalent must be used for onshore facilities to meet SPCC requirements:
• Dikes, berms, or retaining walls sufficiently impervious to contain oil
• Curbing or drip pans
• Sumps and collection systems
• Culverting, gutters, or other drainage systems
• Weirs, booms, or other barriers
• Spill diversion ponds
• Retention ponds
• Sorbent materials.
