Many major industries often require the storage of chemicals, petroleum products and other reactive solvents in large quantities. These materials can be held in and around storage tanks, berms, basins, reservoirs, holding ponds and other containment systems, but leaks or other failures can contaminate the surrounding environment. 

Containment lining systems, which often consist of elastic or PVC liners, polyesters or hybrid polymers, can protect the storage structure from corrosion or chemical attack and contains leaks and spills.

Who Uses Containment Liners?

The oil and gas industry frequently uses containment lining systems to prevent fuel spills from leaching into the groundwater or surrounding environment. Containment lining systems are also frequently used in industries that store chemicals or hazardous waste on site. Other applications include chemical containment at petrolatum tank farms, wastewater runoff basins and water treatment and mining holding ponds.

What Are the Types of Containment Liners?

Chemical containment liners can be designed for use with primary or secondary containment systems, such as bolted or welded steel tanks or concrete vaults, tanks or ponds. Different types of liners may be needed for short-term compared to long-term use. 

Containment liners can be applied in such forms as sheets or panels as well as spray coatings. Effective containment linings will fully adhere to the substrate, seal all gaps and create an impermeable barrier between the chemicals and the containment structure, whether concrete, metallic or made of another material.

Containment liners are often constructed from geomembranes, which the American Society for Testing and Materials (ASTM) describes as very low permeability synthetic membrane liners or barriers used with geotechnical engineering related materials in order to control fluid migration in a man-made project, structure or system. 

Composite containment liners are often constructed using such materials as high-density polyethylene (HDPE), very flexible polyethylene, polyvinyl chloride (PVC), flexible polypropylene and ethyl propylene diene monomer. [EPA-2]

How Long Do Containment Liners Last?

Geomembrane liners for spill containment must be able to resist damage such as tears and punctures, as well as environmental stress cracking and thermal contraction and expansion. Underground geomembranes must withstand potential damage while being installed, while exposed or aboveground geomembranes must withstand sunlight, weather and surface activity.

Depending on such factors as design, material thickness, regularity of maintenance, durability and the nature of materials the liner is exposed to, liners can last several decades without needing replacement.

Alternately, a study performed durability tests in laboratory and field conditions and concluded that some HDPE geomembranes can have a potential service life of hundreds of years.

Rules and Regulations for Containment Systems

The Environmental Protection Agency is one of the primary regulatory bodies overseeing chemical containment and storage in the United States. The Occupational Safety and Health Administration as well as state and local municipalities may have additional rules codes and ordinances relevant to containment systems.

As part of the 1973 Clean Water Act, the EPA first introduced requirements for Spill Prevention, Control and Countermeasure (SPCC) for fuel and chemical storage. In 1996, an EPA report estimated that more than 80 percent of aboveground storage tanks (ASTs) did not have impervious liners as part of their secondary containment.

The EPA presents specifications in its hazardous waste storage regulation 40 CFR 264.175. This requires that secondary containment systems be impervious and free of gaps or cracks. It must have either a sloped design or a means for quick remove of leaking or spilled material. It must have capacity to contain at least 10 percent of the total volume of the primary container or 100 percent of the volume of the largest container, whichever is larger. The system must either prevent precipitation or run-on from entering or have capacity to contain it. Material leaked or spilled into the secondary containment area must be removed as quickly as possible to avoid overflow and potential environmental contamination. 

Why BCI?

Chemical containment liner systems are products vital to the prevention of chemical leaks and spills from tanks, basins and holding ponds into the environment. BCI’s containment liners offer such advantages as easy installation, high durability under heavy traffic, easy cleaning for potential reuse and few to no maintenance needs. The most effective geomembrane liners will provide the container with long-term protection from corrosion, the elements and the adverse effects of fuels and other chemicals.
