Even though its methane emissions comprise a relatively small piece of the industry pie, the distribution sector of the natural gas industry is actively seeking ways to calculate and mitigate its methane emissions.
While the industry is working on technologies and approaches for mitigating emissions, it is also important to improve the way in which emissions are quantified. By establishing reasonable baselines, utilities will be able to provide more accurate reports about their emissions profiles and implement mitigation and reduction programs.
"It’s important for us to help the industry better quantify its methane emissions profile and incorporate this data into an overall mitigation strategy that puts safety and the environment at the top of the priority list," says Paul Armstrong, director of business development at GTI.
New proposed additions to the Pipeline and Hazardous Materials Safety Administration (PHMSA) integrity management program may require operators to test pipe segments located in high-consequence areas (HCAs) and to "devote additional focus, efforts, and analysis…to ensure the integrity of [those] pipelines." With these additions come Integrity Verification Process (IVP) regulations.
As it stands now, these requirements would mandate pipeline operators to verify maximum allowable operating pressure (MAOP) and material properties of gas transmission lines, including pipelines constructed before 1970 that had previously been grandfathered from testing protocols.
Recognizing that new methodologies and technologies are needed to improve the accuracy and reduce the costs associated with these new integrity inspections, GTI is working with industry partners, with funding from OTD, to fill technology gaps.
