The process we use for detecting methane gas at affected facilities is the preferred method accepted by the EPA.
METHANE GAS LEAKS
The Quad Oa regulation is very clear on the detection by an Optical Gas Imaging (OGI) camera;
60.5397a What fugitive emissions GHG and VOC standards apply to the affected facility which is the collection of fugitive emissions components at a well site and the affected facility which is the collection of fugitive emissions components at a compressor station?
You must monitor all fugitive emission components, as defined in§ 60.5430a, in accordance with paragraphs (b) through (g) of this section. You must repair all sources of fugitive emissions in accordance with paragraph (h) of this section. You must keep records in accordance with paragraph (i) of this section and report in accordance with paragraph (j) of this section. For purposes of this section, fugitive emissions are defined as: Any visible emission from a fugitive emissions component observed using optical gas imaging or an instrument reading of 500 ppm or greater using Method 21.
You must develop an emissions monitoring plan that covers the collection of fugitive emissions components at well sites and compressor stations within each company-defined area in accordance with paragraphs (c) and (d) of this section.
The OGI we use, is the same system the EPA and government agencies will be using to inspect sites during the current administration.
