  • UL 1316 and UL 1746: These Underwriters Laboratories (UL) standards apply to fiberglass tanks used for storing chemicals and fuels. They ensure that the tanks meet specific safety and performance criteria.

Installation Requirements

The installation of fiberglass tanks is subject to regulatory oversight to ensure that the tanks are installed correctly and safely. Some of the key considerations include:

  • Building Codes: Local building codes may dictate where and how fiberglass tanks can be installed. For example, in some areas, fiberglass water tanks must be installed above ground to prevent contamination from groundwater.
  • Environmental Protection Agency (EPA) Regulations: The EPA regulates underground storage tanks (USTs), including fiberglass tanks, to prevent leaks and environmental contamination. Tanks must be installed with leak detection systems and corrosion protection.
  • Seismic Considerations: In regions prone to earthquakes, fiberglass tanks must be installed following seismic standards to prevent damage during an earthquake.

Usage and Maintenance Regulations

Once a fiberglass tank is installed, there are ongoing regulatory requirements for its usage and maintenance:

  • Regular Inspections: Many jurisdictions require regular inspections of fiberglass tanks to ensure they remain in good condition and do not pose a risk of leaks or contamination. For example, the EPA requires USTs to be inspected every three years.
  • Tank Cleaning and Maintenance: Fiberglass water tanks used for potable water must be cleaned and maintained to prevent the growth of harmful bacteria and algae. The frequency and methods of cleaning may be regulated by local health departments.
  • Documentation and Recordkeeping: Tank owners are often required to keep records of inspections, maintenance, and any repairs performed on the tanks. These records may need to be presented to regulatory authorities upon request.

Environmental Impact and Compliance

Environmental regulations play a significant role in the use of fiberglass tanks, particularly those used for storing chemicals and hazardous materials. Compliance with these regulations is crucial to avoid fines and legal issues:

  • Spill Prevention, Control, and Countermeasure (SPCC) Plans: The EPA requires facilities that store large quantities of oil or hazardous substances in fiberglass tanks to develop SPCC plans. These plans outline the measures in place to prevent spills and the steps to take in case of a spill.
  • Secondary Containment Requirements: In some cases, fiberglass tanks must be installed with secondary containment systems to prevent leaks from contaminating the surrounding environment. This is particularly important for tanks storing hazardous substances.
  • Air Quality Regulations: Fiberglass tanks storing volatile substances may be subject to air quality regulations that limit the emission of harmful vapors. These regulations may require the installation of vapor recovery systems.

Industry-Specific Regulations

In addition to the general regulations mentioned above, certain industries have specific requirements for using fiberglass tanks:

Water Treatment and Supply Industry

Fiberglass water tanks used in water treatment plants or municipal water supply systems must comply with additional regulations to ensure the safety and quality of the water:

  • Safe Drinking Water Act (SDWA): The SDWA sets standards for drinking water quality in the United States. Fiberglass water tanks used in public water systems must meet these standards to ensure that the stored water is safe for consumption.
  • State and Local Health Department Regulations: Many states and localities have additional regulations governing the use of fiberglass water tanks in public water systems. These regulations may cover everything from the materials used in the tanks to the methods of water treatment.

Chemical and Petrochemical Industry

Fiberglass tanks used to store chemicals, fuels, and other hazardous substances are subject to stringent regulations:

  • Occupational Safety and Health Administration (OSHA) Standards: OSHA sets regulations to protect workers from the hazards associated with the storage and handling of chemicals. Fiberglass tanks used in these industries must meet OSHA standards for safety and containment.
  • Department of Transportation (DOT) Regulations: If fiberglass tanks are used to transport chemicals or hazardous materials, they must comply with DOT regulations. These regulations ensure that the tanks are safe for transport and that they do not pose a risk to public safety.
