In the world of process safety and piping design, Hydrostatic Relief Valves (HRVs)—often simply called thermal relief valves—are the unsung heroes that prevent piping ruptures during periods of inactivity. While a standard Safety Relief Valve (SRV) protects against massive surges or process upsets, the HRV is specifically designed to handle the thermal expansion of trapped…...
Respondent is the owner and operator of the natural gas compressor stations. The Facilities receive natural gas from well sites, separate out liquids from the natural gas and route the natural gas liquids to aboveground storage tanks at the Facilities. The natural gas is compressed and then sent via pipeline to gas plants for further…...

The Environmental Protection Agency (EPA), the Occupational Safety and Health Administration (OSHA), and the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) (“we”) are issuing this advisory as part of an ongoing federal effort to improve chemical risk management, and to advance safety and protect human health and the environment. This advisory contains information on…...
Over the last several years we have come across several facilities that handle anhydrous ammonia and have a dangerous misunderstanding of “hazardous locations”. It seems that somewhere/someone had informed them that their engine room(s) did not need proper ventilation since they were below the 10,000 pound PSM/RMP threshold. They were badly misinformed and here’s why……...
