9.2 Sources of data
For the nonpoint data category, SLTs have four options for providing data to the NEI for the Oil and Gas Production Sector. They may: 1) accept the tool with the defaults populated in the tool by EPA, 2) choose to provide EPA with input data to incorporate in the tool, 3) run the tool themselves (presumably updating the inputs and subtracting point sources), or 4) use their own tools and methodology to provide estimates. In addition, some SLTs submit emissions data for the point data category. Table 9.2 indicates the source of Oil and Gas emissions for each SLT across both the Nonpoint and Point data categories.
