Los Angeles Methane Zones & Methane Buffer Zones

Historical oil pumping fields and natural gas production wells are the main sources of methane gas hazards in shallow soil. Landfills, as well as the areas surrounding them are another cause of methane soil gas. Awareness on the hazards of methane soil gas rises from explosions in central Los Angeles during the 1980s. Thus, the LADBS and other local agencies have require methane testing and methane mitigation, as well as methane barrier deputy inspection, within these special methane zones and methane buffer zones.

Why a Methane Deputy Inspector is in Need

Methane mitigation systems are in place to protect the occupants of buildings from life threatening explosions. Naturally, the oversight agencies want to make sure these systems are built correctly, so nobody gets hurt. Consequently, a methane mitigation inspector has the assignment to validate the integrity of it’s build, on behalf of the government agency. And this individual is nominally a trusted professional, with proven experience in the testing, design and construction of mitigation systems.

Methane Testing

Methane testing is the process by which all deputy inspection services begin. To illustrate, a site with methane hazard zoning, initially requires a methane test to develop a sense of the site-specific mitigation level. This task is overseen by a professional geologist, and follows agency and industry standards. From there, a methane mitigation plan becomes necessary, and uses the data resulting from the methane soil gas test. A methane deputy inspector is not required to oversee methane soil gas testing procedures.

Methane Mitigation Plan Design

Upon the completion of a methane test, geologists and engineers then design a mitigation plan. The basis of the plan covers the specific structural and architectural components of the development to be, and implements passive and active systems to prevent methane gas from migrating indoors. Such plans can be complex, especially pertaining to multi-family and commercial developments with subterranean features, within high methane hazard zones. Ultimately, methane mitigation plans must get approval by the local building department before construction can commence. Although a deputy inspector does not actively prepare a mitigation plan, they must thoroughly review them, and validate compliance and approval by the lead oversight agency. And in the field, a methane deputy inspector has the responsibility of making sure the contractors build precisely in accordance with the final mitigation plan.

How to find a Methane Deputy Inspector

Each oversight agency manages a list of available methane deputy inspection professionals. For example, the City of Los Angeles administers a Public Roster of Deputy Inspectors, for all fields of work. And within this roster, are the list of available methane deputy inspectors, as well as other disciplines. There is a strict qualification process for such inspectors, as they are private professionals that the government agencies choose to legally rely on, in terms of quality assurance.

Rosters are in Alphabetical Order

Agency inspector lists are usually in alphabetical order. And there is no order or preference as to price, reliability or quality of service. As a result, agencies do not advise solely contacting the individuals on the first page. Instead, best results come about when thoroughly reviewing the document, and contacting multiple inspectors with names from the letters “A” to “Z.”
