SECONDARY CHEMICAL CONTAINMENT LINING

Secondary Chemical Containment Lining Services in Texas and NWLA

In 2020, the United States was the number one oil and gas producer in the world, with five U.S. states accounting for 71% of the total oil produced. The Gulf of Mexico accounts for 14.6%, which is regulated by the federal government. Texas, the number one oil-producing state, outproduces every other state in the country by a wide margin, while Louisiana ranks in the top 10. Needless to say, oil and gas is a large industry in both of these states.

Oil and gas production is a heavily regulated business, and understandably so. As such, the two states must abide by the strict rules and regulations established to protect land and natural resources from messy spills and leaks. Oil spills, such as the 1989 Exxon Valdez disaster, can lead to a number of repercussions. Contaminated drinking water, public health issues, and devastation to natural resources and wildlife are just a few of these. With this in mind, how oil and gas are extracted, processed, transported, and stored is a concern of many, from oil businesses and local and federal governments to the general population and environment. To avoid a natural disaster and the several disasters that result from it, oilfield storage and containment equipment aim to prevent any crude materials from entering navigable U.S. waters. In addition, the EPA requires secondary containment systems in case the primary system fails.

Any method, mechanism, or control measure preventing a spill from leaving a designated area is considered secondary containment. In the event that the primary containment, such as a bulk storage container, pipelines, a mobile or portable container, or other oil-filled equipment fails, this secondary lining can be a crucial measure of defense. 

Protecting the spaces in and around tanks, including concrete tank pads, flooring, secondary containment, and wastewater regions is just as important. To prevent migration into the concrete surfaces, these sections must endure spills, splashes, and tank leaks from exposure to harsh chemicals such as strong acids, alkalis, gases, solvents, and oxidizers.

Spills at oil and gas plants are often devastating. They endanger on-site workers, damage the immediate environment, and possibly cause long-term health problems in the neighboring areas. As a result, oil and gas companies follow strict regulations that are established by the Environmental Protection Agency (EPA). The use of secondary spill containment as part of the oil containment solution is one of the regulations that is required by these EPA standards.

Bulk storage tanks or containers, pipelines or piping, or mobile or portable containers are the most common primary containment methods. The EPA requires a secondary containment system developed or constructed around the primary system to prevent hazardous spills from contaminating the environment, keep hazardous fluids separate from the surrounding areas, and to make sure a spill doesn’t cost oil and gas companies valuable product.

The secondary containment system provides a secure, temporary location for spilled oil until the source of the leak or spill is located and subsequently fixed. It also allows time for the oil to be removed from all areas where it has pooled. This prevents it reaching groundwater or nearby shorelines, as well as any nearby wildlife, birds, or ecosystems.

The EPA does not specify what a secondary chemical containment system must be, but rather requires that it is able to hold the entire volume of what is contained in the primary system (plus any rainfall, if necessary). Anything from a dike, berm, or concrete wall surrounding your primary container to simple trays, spill pallets, absorbents, or even a sloped room that collects the oil or fuel at one end until it can be cleaned up can serve as a secondary containment system.

Containment liner systems are frequently used by the oil and gas industry to prevent fuel spills from getting into groundwater or the environment. Industries storing chemicals or hazardous waste on site often use chemical containment lining systems, as well. Chemical containment at petroleum tank farms, wastewater runoff basins, water treatment, and mining holding ponds are other viable applications.

Chemical containment liners fit primary or secondary containment systems like bolted or welded steel tanks, concrete vaults, tanks, or ponds. Whether it is needed for short-term and long-term determines the type of liner needed. Containment liners come in a variety of shapes and sizes, including sheets, panels, and spray coatings. Effective containment linings cling to the substrate completely, seal any gaps, and form a barrier between the chemicals and the containment structure that cannot be breached.

Geomembranes are used in very low permeability synthetic membrane liners or barriers used with geotechnical engineering-related materials. According to the American Society for Testing and Materials, this is to limit fluid migration in a man-made project, structure, or system.

High-density polyethylene (HDPE), highly flexible polyethylene, polyvinyl chloride (PVC), flexible polypropylene, and ethyl propylene diene monomer (EPA-2) are all materials commonly used to make composite containment liners.

Chemical containment geomembrane liners must be resistant to tears and punctures, as well as environmental stress cracking and thermal contraction and expansion. Exposed or above-ground geomembranes must endure sunshine, weather, and surface activities, while underground geomembranes must withstand potential damage during installation.

As a result, liners may survive several decades without needing to be replaced, depending on criteria such as design, material thickness, regularity of maintenance, durability, and the nature of materials the liner is exposed to. In fact, a study revealed that some HDPE geomembranes can have a potential service life of hundreds of years after conducting durability tests in the lab and in the field.

Rules and Regulations for Containment Systems

One of the key regulatory authorities in charge of chemical containment and storage in the United States is the EPA. Additional standards, codes, and ordinances governing containment systems may come from the Occupational Safety and Health Administration (OSHA), as well as state and local governments.

The EPA originally imposed Spill Prevention, Control, and Countermeasure (SPCC) standards for fuel and chemical storage as part of the 1973 Clean Water Act. That’s because, according to a 1996 EPA analysis, more than 80% of aboveground storage tanks (ASTs) lacked impermeable liners as part of their secondary containment.

The EPA’s hazardous waste containment regulation and standards can be found in 40 CFR § 264.175. This code specifies that impermeable secondary containment systems, free of gaps and fissures, are required. The liner system needs to be sloped or able to quickly remove leaking or spilled material and its capacity must be at least 10% of the entire volume of the primary container or 100% of the volume of the largest container, whichever is greater. The system must also be capable of either preventing or containing rainfall or run-on. Avoiding overflow and potential environmental contamination is key, and any material leaked or spilled into the secondary containment area must be removed quickly.

Secondary Chemical Containment Lining in Shreveport, LA and East Texas

The primary purpose of a secondary chemical containment system is to isolate hazardous chemical spills, splashes, or leaks until they can be properly handled. The most effective chemical containment liners protect the container from corrosion, the elements, and harmful effects of fuels and other chemicals. Rest assured, the secondary chemical containment lining services we offer at Target Industries provide these protections and more. What’s more, our liners provide a number of advantages such as easy installation, great durability under heavy traffic, easy cleaning for eventual reuse, and little to no maintenance.

At Target Industries, we’re devoted to keeping your worksites safe and following environmental safety regulations. Using a chemical containment system to protect your employees, job site, product, and the environment is critical.
