More Information About The SPCC Regulation

What is SPCC?

The goal of the SPCC program is to prevent oil spills into waters of the United States and adjoining shorelines.

What is considered a farm under SPCC?

Under SPCC, a farm is: “a facility on a tract of land devoted to the production of crops or raising of animals, including fish, which produced and sold, or normally would have produced and sold, $1,000 or more of agricultural products during a year.”

Is my farm covered by SPCC?

SPCC applies to a farm which: Stores, transfers, uses, or consumes oil or oil products, such as diesel fuel, gasoline, lube oil, hydraulic oil, adjuvant oil, crop oil, vegetable oil, or animal fat; and Stores more than 1,320 US gallons in aboveground containers or more than 42,000 US gallons in completely buried containers; and Could reasonably be expected to discharge oil to waters of the US or adjoining shorelines, such as interstate waters, intrastate lakes, rivers, and streams.

Dura Life® CONTAINMENT Systems

The Leading Provider of Secondary Containment Systems for the Oil, Gas, Petrochemical & Agricultural Industries. The first in the industry to engineer and develop the steel concept for secondary containment, we use only the highest quality, chemically treated, galvanized steel. The 65,000 PSI, heavy-duty 10, 11, 12 & 14 gauge corrugated steel construction resists rust and corrosion even in the harshest environments.

Three Kinds of Containment

Dura Life Dynamic Loading Secondary Containment System

Dynamic Loading Containment Systems are designed and manufactured with additional safety factors to withstand higher loads.
  • The strongest containment system on the market today without a single reported failure in the entire history of the brand.

  • Built with 10 gauge steel walls and patented Zpost’s set in concrete that protects the structure from frost heave.

  • Designed by professional engineers that utilize state-of-the-art Finite Element Analysis tools to scrutinize every component in order to maximize durability and increase strength.

Dura Life Ground Guard Zero Ground Disturbance Containment Systems

Ground Guard Systems require zero ground penetration and are a perfect alternative for areas where underground systems are not an option.
  • These containment systems require ZERO ground penetration and/or disturbance - taking away timely site identification that is typically needed when installing systems requiring post holes set in concrete.

  • Ground Guard Systems take the risk of puncturing existing pipelines away by removing the threat of digging underground.

  • Concrete materials are eliminated entirely, making the Ground Guard the toughest, all-steel system in the industry.
