Developer Resources

The following tools provide information, data, or other support for developers working with environmental review and permitting systems.

NEPA and Permitting Data and Technology Standard

The data standard establishes a government-wide data and technology standard for NEPA, and other related permits and reviews. This data standard provides agencies with a common digital language to facilitate interoperability and automatic data exchange among systems. These pages provide an overview of the data standard, description of entities and their properties, and example relationship diagrams.

NEPA and Permitting Data and Technology Standards GitHub Resources

This repository includes a toolkit for implementation of the data standard, technical documentation, and scripts that can aid in validating implementations of the data standard. Current implementations include SQL, JSON, YAML, and OpenAPI.

Example Swagger OpenAPI Page

This is an example of a Swagger page for an OpenAPI specification that serves as a guide for agencies implementing APIs (or Application Programming Interfaces) for environmental review and permitting systems. Note that this is not a functional API and there is no centralized database of this information. As part of their implementation of the Permitting Technology Action Plan, agencies should be working toward creating APIs that follow this specification.

CE Explorer - Categorical Exclusion Data

The Categorical Exclusion (CE) Explorer provides a digitized, searchable list of Federal agency categorical exclusions. The CE Explorer is populated from a dataset of categorical exclusions available here.

NEPATEC 2.0

The Department of Energy’s PermitAI project has released a large dataset of environmental review documents, called NEPATEC 2.0. This dataset of ~80,000 NEPA documents has been enriched using AI with metadata matching CEQ’s data standard and includes categorical exclusion determinations, environmental assessments, and environmental impact statements.
