Mechanical Extraction System
Mechanical Extraction System: Per the Los Angeles Department of Building and Safety (LADBS) Methane Code, Ordinance Number 175790, a Mechanical Extraction System is one of the Active Methane Mitigation criteria for methane mitigation systems in buffer zones and methane zones. A mechanical extraction system uses machines that remove methane gas from below the impervious membrane. And this includes the use of fans, blowers, or other powered devices that are above and below the methane barrier itself.
