Appendix A: Oil and Gas NEI SCCs This Appendix provides a list SCCs that are considered representative of the oil and gas sector from the 2008 NEI point, nonpoint and nonroad mobile inventories. We removed these SCCs for counties where we used WRAP Phase III oil and gas emissions in the 2007v5 platform. This complete list of potential SCCs are provided in Table A-1. Many of these SCCs were not reported in the 2008 NEI –see column “Reported?” equals “N”. The complete list is provided here to aid in data reconciliation for future versions of the NEI that may have some SCCs not in the 2008 NEI. In addition, we did not remove the nonroad diesel vehicle SCC = 22700100100; these emissions are very small but potentially double-counted in the 2007 platform.
