Hazardous Material Containment
The Code of Federal Regulations (CFR) to protect the environment requires by federal law that all hazardous wastes or constituents be positively contained.
In 1987, the Environmental Protection Agency (EPA) passed CFR 40 requiring a secondary means of containing spilled materials including hazardous chemicals.
Two deadlines for new regulations are slowly approaching, one for the secondary containment of underground storage tanks (USTs) and the other for aboveground storage tanks (ASTs). Many USTs and ASTS are made of concrete.
Beginning December 31, 2009, corrosion-protected single-wall USTs and small-diameter piping in contact with the soil must have secondary containment. On January 1, 2010, all single-wall, field-erected ASTs must have secondary containment beneath the tank, and single-wall bulk product piping in contact with the soil must have secondary containment unless deferred by an API 570 Integrity Assessment. The secondary containment must function effectively for a period of time sufficient to allow proper spill cleanup without damage to the environment.
SPI polyurea spray elastomer technology meets the new requirements. Different formulated products address the new requirements with a monolithic, impervious layer that adhere to various substrates. When solid substrates are not present, geotextiles can be used with polyurea.
Polyurea’s rapid set time allows a quicker return to service in ambient conditions, including cold weather. The polyurea lining remains flexible and eliminates cracking found in other liquid applied coatings.
The U.S. military uses polyurea for lining various fuel storage containment areas. Most of these areas formally used epoxy paint systems applied on concrete, but the epoxy cracked with the substrates movement causing leakage. Polyurea bridges cracks and yields a superior containment material.
With the resurgence of oil and gas exploration in the U.S., containment areas for the fractionation fluid are required at each drilling site. A designed containment area is prepared, metal support walls constructed and polyurea spray system is applied over a geotextile fabric. The polyurea system bonds to the wall area and geotextile fabric to provide for a seamless, leak-free area. The storage tanks are then set within the area and piped in the same day as the liner system installation.
