Glossary:Leak detection and repair
A programme to identify and repair the equipment or infrastructure that can be a source of emissions due to leaks from pressurized equipment. It is often accomplished by a periodic inspection survey to identify leaks, followed by repair of any found leaks.
(Note - Within the LDAR programme, a variety of techniques can be employed for detecting the leaks. While LDAR in certain jurisdictions can have a specific regulatory definition, it is more generally used to describe the processes and systems by which leaking equipment is identified, prioritized and then repaired.)[1]
