PHMSA Mega Rule
In 2020, the Pipeline Hazardous Materials and Safety Administration (PHMSA) implemented the Gas Mega Rule, doubling the onshore gas transmission regulations.
Experts in the Mega Rule
Operators must test all pipelines for Maximum Allowable Operating Pressure (MAOP) with comprehensive records to verify. There are also new requirements for the frequency of sampling and testing.
There are now new repair requirements for High Consequence Areas (HCAs) and non-HCAs, and operators must inspect pipelines within 72 hours of an extreme weather event. Additionally, regular pipeline integrity management must be performed. Leak detection systems must be expanded and accommodate inline inspection tools.
PHMSA now has greater authority to issue emergency orders for unsafe conditions or faulty pipe components. Pipeline operators must understand pipeline safety threats, HCAs, and Moderate Consequence Areas (MCAs).
