PermitTEC v0.1 Standardized Metadata Corpus of NEPA Litigation Documents

Summary

Pacific Northwest National Laboratory has released PermitTEC v0.1, a standardized metadata corpus of 761 federal court litigation cases related to the National Environmental Policy Act (NEPA). This initiative addresses the challenge of poorly cataloged and inaccessible NEPA litigation data, which hinders systematic analysis and modernization of permitting processes. PermitTEC v0.1 is integrated with NEPATEC v2.0, a corpus of over 140,000 NEPA documents across 60,000 projects, using three LLM-driven matching approaches. Of the 761 cases, 223 (29.3%) were successfully linked to unique NEPA projects, with 98.2% of these linked projects being Environmental Impact Statements. The corpus covers litigation from the 1970s to 2025, and notably, 341 (44.8%) of NEPA challenges in the dataset still lack a corresponding NEPATEC project entry.
