WASHINGTON, September 17, 2020 – The American Petroleum Institute (API) today released the fifth edition of API 2350, a key safety standard designed to help operators of oil storage facilities implement comprehensive overfill prevention systems (OPS), which ensure that oil and other products are transferred to storage tanks safely, without overfilling or mechanical damage.

“The updated standard will help operators receive petroleum products at their storage facilities, using the latest techniques and technologies to prioritize safety and spill prevention  while ensuring safety and environmental sustainability practices are maintained,” API Global Industry Services (GIS) Senior Vice President Debra Phillips said. “This new edition of API 2350 addresses practices at storage facilities, which are increasingly important to the industry as supply and demand trends are affected by the current pandemic, and specifically advances techniques to prevent overfilling.”

The fifth edition, titled Overfill Prevention for Storage Tanks in Petroleum Facilities, places increased emphasis on areas such as reaction times to overfill alarms, spill prevention programs, management systems, industry experience and improved technology. The new edition also provides a wide range of offerings to account for operational differences between each storage facility, while providing more options to operators to advance safety and environmental protection.

API standards are developed under API’s American National Standards Institute (ANSI) accredited process, ensuring that the API standards are recognized not only for their technical rigor, but also for their third-party accreditation which facilitates acceptance by state, federal and increasingly international regulators. The GIS division is responsible for standards setting, certification, training, events, publications and safety programs for industry operations.

API represents all segments of America’s oil and natural gas industry. Our more than 600 members produce, process and distribute most of the nation’s energy. The industry supports more than ten million U.S. jobs and is backed by a growing grassroots movement of millions of Americans. API was formed in 1919 as a standards-setting organization. In our first 100 years, API has developed more than 700 standards to enhance operational and environmental safety, efficiency and sustainability.
