Please see Reporting Form Instructions instructions on downloading the blank reporting form and uploading the completed reporting form.
You may also refer to Optional Calculation Spreadsheet Instructions to download the Subpart W calculation spreadsheet.

This page provides an overview of the Subpart W local distribution companies source category e-GGRT reporting requirements.

The local distribution companies source category is applicable to Natural Gas Distribution.

If the facility has the source type, the Best Available Monitoring Methods and Missing Data table must be completed.

For further information, see Best Available Monitoring Methods and Missing Data Reporting.

Reporting Requirements

Note: If you do not have any metering-regulating stations or transmission-distribution stations enter zero, do not leave blank.

The facility is required to report:

Total number of above grade T--D transfer stations in the facility (98.236(c)(16)(i))
Number of years over which all T--D transfer stations will be monitored at least once (98.236(c)(16)(ii))
Number of T--D stations monitored in calendar year (98.236(c)(16)(iii))
Total number of below grade T--D transfer stations in the facility (98.236(c)(16)(iv))
Total number of above grade metering-regulating stations (this count will include above grade T--D transfer stations) in the facility (98.236(c)(16)(v))
Total number of below grade metering-regulating stations (this count will include below grade T--D transfer stations) in the facility (98.236(c)(16)(vi))
Annual CO2 emissions from all above grade T--D transfer stations combined (98.236(c)(16)(xvii))
Annual CH4 emissions from all above grade T--D transfer stations combined (98.236(c)(16)(xvii))
Annual CO2 emissions from all below grade T--D transfer stations combined (98.236(c)(16)(xviii)
Annual CH4 emissions from all below grade T--D transfer stations combined (98.236(c)(16)(xviii))
Annual CO2 emissions from all above grade metering-regulating stations (including T--D transfer stations) combined (98.236(c)(16)(xix))
Annual CH4 emissions from all above grade metering-regulating stations (including T--D transfer stations) combined (98.236(c)(16)(xix))
Annual CO2 emissions from all below grade metering-regulating stations (including T--D transfer stations) combined (98.236(c)(16)(xx))
Annual CH4 emissions from all below grade metering-regulating stations (including T--D transfer stations) combined (98.236(c)(16)(xx))
Annual CO2 emissions from all distribution mains combined (98.236(c)(16)(xxi))
Annual CH4 emissions from all distribution mains combined (98.236(c)(16)(xxi))
Annual CO2 emissions from all distribution services combined (98.236(c)(16)(xxii))
Annual CH4 emissions from all distribution services combined (98.236(c)(16)(xxii))

The emissions under 98.236(c)(xvii) and (xviii), above and below grade T-D stations are also reported under 98.236(c)(16)(xix) and (XX), above and below grade metering-regulating stations. To prevent double counting of these emissions the reporting system does not include T-D transfer stations in the source total. This has caused confusion but this specifically required under 98.236(c)(16)(xix).

The facility can optionally report:

Note: Reporting of these data elements is optional. EPA has deferred the deadline for reporting these data elements until March 31, 2015 (see 76 FR 53057, published Aug. 25, 2011). You may wait until the 2015 deadline to report these data, or you may voluntarily report these data elements this year.These data elements may be subject to public availability once reported to EPA.

Leak factor for meter/regulator run developed in Equation W-32 of 98.233 (98.236(c)(16)(viii))
Number of miles of unprotected steel distribution mains (98.236(c)(16)(ix))
Number of miles of protected steel distribution mains (98.236)(c)(16)(x))
Number of miles of plastic distribution mains (98.236(c)(16)(xi))
Number of miles of cast iron distribution mains (98.236(c)(16)(xii))
Number of unprotected steel distribution services (98.236(c)(16)(xiii))
Number of protected steel distribution services (98.236(c)(16)(xiv))
Number of plastic distribution services (98.236(c)(16)(xv))
Number of copper distribution services (98.236(c)(16)(xvi))

Total Emissions

The total emissions roll-up at the top of the sheet reflects the sum of the CO₂ equivalents of each gas emission reported for the source type. These summations are reflected and aggregated on the Introduction tab.
