NACE International
This corrosion & corrosion control technical association was established in 1943 as the National Association of Corrosion Engineers by eleven corrosion engineers in the pipeline industry. These founding members were involved in a regional cathodic protection group formed in the 1930s, when the study of cathodic protection was introduced. With more than fifty years of experience in developing corrosion prevention and control standards, NACE International has become the largest association whose membership is committed to the study of corrosion.

National Fire Protection Association (NFPA)
NFPA is a worldwide leader in providing fire, electrical, and life safety to the public. Established in 1896, the mission of the international, nonprofit, member organization is to reduce the worldwide burden of fire and other hazards on the quality of life by developing and advocating scientifically based consensus codes and standards, research, training, and education. NFPA is currently developing the first consensus-based building code. Membership in NFPA totals more than 69,000 individuals from around the world and more than 80 national trade and professional organizations.  It is perhaps best known as the producers of the National Electric Code (NEC).

United States Environmental Protection Agency (US EPA)
The mission of the U.S. Environmental Protection Agency is to protect human health and to safeguard the natural environment—air, water, and land—upon which life depends.
EPA’s purpose is to ensure that National efforts to reduce environmental risk are based on the best available scientific information.  Federal laws protecting human health and the environment are enforced fairly and effectively.  Environmental protection is an integral consideration in U.S. policies concerning natural resources, human health, economic growth, energy, transportation, agriculture, industry, and international trade; and these factors are similarly considered in establishing environmental policy.  Environmental protection contributes to making our communities and ecosystems diverse, sustainable and economically productive. The United States plays a leadership role in working with other nations to protect the global environment.

US EPA Office of Underground Storage Tanks (US EPA OUST)
The Office of Underground Storage Tanks (OUST) was created in the summer of 1985 to carry out a Congressional mandate to develop and implement a new regulatory program for Underground Storage Tank (UST) systems.  The mission of the OUST program is to protect human health and environmental quality by creating conditions under which good management of Underground Storage Tank systems (USTs)is common business practice. Good tank management includes prevention, detection, and timely, cost-effective cleanup of releases. One of their goals is to prevent the creation of a new generation of leaking USTs. Reaching this goal requires that USTs be protected from corrosion, protected against spills and overfills, equipped to detect releases, and be properly installed and maintained.  Another goal is to ensure that UST releases are detected and cleaned up promptly and cost-effectively to the extent necessary to protect human health and the environment.  Regular monitoring of UST systems by owners and operators will ensure that releases are promptly detected.
