Millions of gallons of hazardous materials are currently stored in out-of-sight underground storage tanks, some as large as a tractor-trailer rig. But out-of-sight should not mean out-of-mind. As prime sources of hazardous material releases, damaged and leaking tanks cause fires, health hazards, and explosions; They also contaminate soil and groundwater. The potential for liability is serious. NCM can alleviate your liability concerns with state-of-the-art testing, corrective services, and long-term management recommendations for both underground and aboveground storage tanks (USTs and ASTs).
Timely ManagementIn addition to annual inspections, it is the owner’s continuing responsibility to ensure that a tank is not leaking, and, if it is, to see that the tank is retrofitted, replaced, or closed without a contaminating product remaining. Warning signs that call for immediate action include the following: Fuel use is higher than normal; tank is taking on water (more than 1/2-inch in 12 hours); oil sheen appears in nearby stream or ditches; vegetation on down-side of tank appears damaged; and visible sign of spill around fill pipe or vent pipe. Owners must also accomplish timely upgrades or replacements in order to comply with environmental regulations.
Expert ServiceNCM provides the most efficient, cost-effective solution for any AST or UST problem as well as closure and deconstruction or demolition of entire tank farms. Scrap metal may be salvaged. With over three decades of hands-on experience, you can count on us for regulatory compliance.
Tanks remain in service during testing. If a tank is identified as a contaminating source, we evacuate the tank contents; clean the tank; recover, separate, and recycle or dispose of the free product; treat contaminated groundwater; recover and vent or treat hazardous vapors; and excavate and treat or dispose of contaminated soil. We complete the project by retrofitting, replacing, or removing the damaged tank. NCM is fully certified to transport and dispose of hazardous waste, if needed.
