Aboveground Storage
Corrpro Canada services aboveground and underground storage tanks that store hazardous liquids and other industrial materials. We also provide protection for breakout tanks that relieve surges in pipeline systems.
Corrpro Canada’s team of certified NACE engineers provides clients with the expertise to design these systems and help prevent failure and corrosion. Corrpro Canada provides storage tank coating for corrosion protection as well as services to routinely monitor and inspect these systems to guarantee that they remain in compliance.
EPA Upgrade Requirements
Corrpro Canada/WRA Tank Mean Time to Corrosion Failure (MTCF™) program provides tank owners with a cost-effective means of minimizing the risk of leaks and of meeting regulatory requirements.
The Corrpro Canada/WRA MTCF™ program of selected tank replacement and upgrading allows the tank manager to plan and budget for activities to minimize exposure to risk and meet regulatory requirements. Corrpro Canada and WRA have developed procedures to:
- Provide the tank manager with definitive information based upon field corrosion engineering tests
- Enable the tank manager to prioritize tank replacement and upgrading activities in descending order of risk
- Protect good tankage with cathodic protection and tank lining retrofit programs
The Corrpro Canada/WRA MTCF™ program is based on proven procedures that allow tank managers to plan, program and budget for tank integrity. It is a proactive means to identify requirements for upgrade and replacement to meet current applicable Federal EPA requirements.
Predicting Corrosion Failure
Recognizing that tank replacement is costly and that a significant number of tanks can be safeguarded against further deterioration by retrofitting with cathodic protection at a tenth of the cost (on average) of replacement, a number of major oil companies set out to determine if they could predict when tanks would fail. At first, they assumed that the rate of external corrosion was a function of age. However, they soon discovered that leaks and tank age were totally unrelated. In 1979, the American Petroleum Institute asked Warren Rogers Associates to examine the physical process of external corrosion to determine if a reliable means of predicting failures could be developed.
The rate of corrosion is a function of the characteristics of the backfill in which the tank system is installed. These include the resistivity, PH, electrical potential, moisture, chlorides, sulfides and stray DC. When taken alone, none of these characteristics, when incorporated in a multi-variate statistical model, were adequate for predictive purposes. However, a reliable means of predicting the rate of corrosion was developed. Using this model, the mean time to corrosion failure (MTCF) and probabilities of a leak could be established.
Since the corrosive characteristics of backfill vary greatly, even within a small geographic area, predicting MTCF for USTs is a site-specific task. The formulation of a mean age to leak establishes a narrow range of useful ages in which the likelihood of failure rapidly increases.
EPA Compliance for Underground Storage Tanks
Federal EPA upgrade compliance requirements for existing underground storage tank systems have renewed interest in the problem of leaking tanks. The requirement that unprotected steel tank systems be replaced or upgraded is a common feature of federal, state and local government regulations.
Those responsible for underground tanks can benefit from the experience of major oil companies who have had tank management programs in place for nearly two decades. These companies have discovered that the cost of such a program can vary tremendously depending on the approach taken.
