Emissions Quantification Validation Process

A validation framework for assessing leak quantification technology is NOT currently available. While there are many leak detection systems commercially available, the technologies that can QUANTIFY emissions rates for prioritizing non-hazardous type 3 leaks are not fully proven for the methane emissions application, especially in natural gas distribution environments. There are several challenges and limitations that exist today in this new area of quantifying methane emissions; particularly for grade 3 leaks. Methods for verifying and prioritizing the measured flow rates from leaks specific to the natural gas distribution infrastructure are still evolving and need specific guidelines for implementation and validation. The overall objective of this project is to work collaboratively as an industry group and with others to identify, apply and test a methodology or set of methodologies that allow a gas distribution operator to VALIDATE the accuracy of measuring, locating and quantifying the methane emissions flow rate from non-hazardous natural gas infrastructure leaks. If successful in validating a technology or combination of technologies that can apply to accurately quantify methane emissions, the proposed effort would allow more data driven decisions based on the greenhouse gas emissions contribution of individual non-hazardous leaks. This validated quantitative flow rate information could aid in prioritization of repair decisions.
