| Title: |
Inspect Flowlines Annually |
| Text: |
Table 1â€"Cost-Effective Options for Reducing Methane Emissions: "Inspect Flowlines (sic) Annually. Flowlines (sic) are normally buried and can develop leaks from internal and external corrosion and abrasion. Many flowlines (sic) are inspected infrequently, and large leaks may go unnoticed for a long time. As a result, leakage from flowlines(sic) is one of the larges sources of methane emissions in the natural gas production sector. Annual flowline (sic) inspection and a regular leak-repair schedule will reduce gas losses and prevent small leaks from growing into major leaks. Leaks in buried flow lines may be detected by using an ultrasound detector, or infrared imaging, or through the temporary introduction of odorant into the gas stream. Walking inspections are more effective using leak-detection or leak-imaging devices or odorants. The average methane emissions from buried flowlines (sic) are estimated to be 53 scf/D per mile."
