ii. Number of service lines grouped by the original service line material type and the replacement or refurbished material type;

iii. Miles of mains added, grouped by material type; and

iv. Number of service lines added, grouped by material type.

3. Identification of each leak from pipeline components that have a leak grade classification ranked as grade 1, 2, or 3, as follows:

i. Blowdown identification number;

ii. The amount of natural gas released, measured in standard cubic feet, as calculated with one of the following methodologies:

(1) The volume of the pipeline segment between isolation valves and the pressure and the temperature of the gas within the pipeline in accordance with 40 CFR 98.233(i)2, incorporated by reference; or

(2) The measurement of emissions using a flow meter in accordance with 40 CFR 98.233(i)3, incorporated by reference;
