Cathodic Protection Systems Vital in Above Ground Storage Tanks

In January 2014, above ground storage tanks (ASTs) containing the chemical 4-methylcyclohexanemethanol (MCHM) was released into Elk River in West Virginia. The leaks, which cursory reports believe to be the likely the result of corrosion, could have been avoided by implementing proper cathodic protection systems.

The facility, operated by Freedom Industries, containing the chemical was located in Charleston, West Virginia. Recently, federal investigators discovered that the spill might have originated from more than one tank and could account for up to 10,000 gallons of MCHM.

This catastrophe, which left the 300,000 residents across nine West Virginia counties without potable water, could have been avoided by taking proper precautions.

The spill is currently being attributed to corrosion in the above ground storage tanks that held the MCHM. Corrosion is a serious and persistent concern for ASTs, which must withstand the elements.

“Above ground storage tanks pose a specific set of problems when it comes to corrosion prevention. The evidence collected by several federal agencies suggests that this hazardous leak was the result of a tank bottom leak,” said Ted Huck, vice president, international sales and practice lead – plants and facilities at MATCOR. “The leak was caused by the corrosion of the tank bottom due to contact of the external tank plate with the soil.

“The resulting soil-side hole could have been prevented by MATCOR’s patented cathodic protection systems. While cathodic protection systems are commonly used in oil and gas storage tanks, they are not mandated and there are tanks across the country that do not have cathodic protection systems installed to protect tank bottoms from leaking.”

Cathodic protection systems are critical for preventing corrosion in ASTs.

Cathodic Protection Systems

The soil-side hole that resulted in the released chemical is a common problem among ASTs. MATOR has developed a reliable protection system for ASTs which uses our unique SPL-Anode system and patented Kynex® technology.
