BUILDING A COMPREHENSIVE LDAR PROGRAM
In the Appalachian basin, PennEnergy Resources takes a proactive and thoughtful approach towards reducing emissions through its Air Quality & Sustainability program. A key element of this program is the comprehensive leak detection and repair (LDAR) program, which monitors all facilities for fugitive leaks via multiple technologies (with prompt, predominantly same-day repairs) and goes well beyond the basic regulatory requirements. Enhanced Leak Detection and Repair Optical Gas Imaging (OGI) Inspections On a monthly basis, PennEnergy conducts OGI camera inspections – triple the frequency required under current regulation. OGI cameras are the cornerstone of the LDAR program, and the most sensitive detection tool employed. Audio, Visual, and Olfactory (AVO) Inspections On a weekly basis, PennEnergy conducts AVO inspections – quadruple the frequency required under current regulation. AVO leaks are detected using senses (sound, sight and smell) by operators familiar with the facilities to frequently hone in on potential leaks. 3rd Party Flyovers In addition to boots-on-the-ground inspections, voluntary aerial inspections are conducted by contractors to detect potential anomalous emissions from above on an annual basis. Emissions Quantification Beginning in 2024, PennEnergy began quantifying leaks with a precision methane analyzer. Based on the current comprehensive dataset, PennEnergy has found that its fugitive emissions profile is significantly less than what would be calculated using conventional emissions factors.
