Measuring, calculating, and understanding emissions from water tanks is accomplished in various ways, but is increasingly consolidating into an industry standard. This work is meant to build from previous studies, share industry experience, and detail the procedure that most accurately represents emissions from water tanks and satisfies regulatory requirements. This includes addressing the "1% rule" and the various interpretations of its implementation. The Sample + Model approach detailed here leverages the strengths of laboratory analysis with the power of thermodynamic modeling to contribute a well-informed emission calculation to industry, regulators, and the community.
