- Local distribution companies (LDCs) report the CO2 emissions that would result from the complete combustion or oxidation of the annual supply of natural gas delivered to end-users, reported as follows: (1) Each meter registering supply of 460,000 thousand standard cubic feet (Mscf) or more during the calendar year, and (2) the sum of all meters registering less than 460,000 Mscf during the calendar year. The total GHG quantity displayed for each LDC in this data set is the sum of these values, reflecting the emissions associated with all natural gas delivered by the LDC during 2010.
- LDCs report the GHG quantity associated with all natural gas deliveries, both gas owned by the LDC and gas not owned by the LDC. Quantities of gas delivered displayed in this data set may differ from data reported to the Energy Information Administration (EIA) because EIA requires separate reporting of these quantities.
Injection of Carbon Dioxide
- Injection of Carbon Dioxide (Subpart UU)
Certain facilities reporting under subpart UU have been granted Research and development (R&D) project exemptions from reporting requirements under 40 CFR part 98, subpart RR "Geologic Sequestration of Carbon Dioxide". A project is eligible for the exemption if it investigates practices, monitoring techniques, or injection verification, or if it is engaged in other applied research that focuses on enabling safe and effective long-term containment of a CO2 stream in subsurface geologic formations, including research and injection tests conducted as a precursor to a larger more permanent long-term storage operation. Facilities that report CO2 received under Subpart UU and hold an R&D project exemption from subpart RR are marked with this icon insert icon in the publication tool. For more information on facilities that have received an R&D project exemption, see: http://www.epa.gov/ghgreporting/reporters/subpart/rr.html
