Geologic Basin Boundaries for Greenhouse Gas Reporting in Contiguous U.S.

Geologic Basin Boundaries (Basins_GHGRP) GIS Layer is a shapefile coverage defining geologic basin boundaries used by the U.S. Environmental Protection Agency's Greenhouse Gas Reporting Program. The layer is limited to the contiguous United States and was last updated in February 2025.

Use Cases

• Map and analyze the spatial distribution of geologic basins across the contiguous United States for environmental reporting.
• Integrate basin boundaries with facility location data to assess greenhouse gas emissions by hydrocarbon-producing basin.
• Support regulatory compliance analysis by defining the geographic scope of onshore production facilities under the GHGRP.

Strengths

• Sourced from the authoritative U.S. Environmental Protection Agency, ensuring regulatory relevance.
• Specifically designed for use in the national Greenhouse Gas Reporting Program, providing a clear use case.
• Updated recently, with a last update recorded in February 2025.

Limitations

• Spatial coverage is limited to the contiguous United States, excluding Alaska, Hawaii, and U.S. territories.
• The dataset's specific attributes, column structure, and total feature count are not provided in the input.
• The underlying data source (AAPG geologic provinces) may have its own classification and temporal limitations.
