Source License Register
Revision: September 18, 2026. This register describes upstream terms, not a promise that every listed source is included in an order. The accepted Service Catalogue and delivered manifest identify the specific releases and contents supplied.
PUDL distributions
Catalyst Cooperative's Public Utility Data Liberation (PUDL) stable distribution is listed under Creative Commons Attribution 4.0 International in the official distribution listing. This includes the PUDL-distributed EIA, FERC and EPA-derived tables identified in our delivered source manifest; it is not a statement that all upstream documents are licensed by Catalyst.
Credit Catalyst Cooperative/PUDL, retain supplied attribution and license notices, link the license and identify modifications. Commercial reuse, redistribution and adaptation are permitted subject to that license. Do not impose legal or technical restrictions that prevent recipients from exercising licensed rights. BaseloadOS normalization must be identified as a modification, not attributed to the agency.
Direct official datasets
| Source | Official rights evidence | Scope and conditions |
|---|---|---|
| EIA-923 direct monthly files | EIA reuse policy | Public data reuse is supported; acknowledge EIA and publication date. Third-party copyrighted material and branding are not automatically included. |
| eGRID | EPA eGRID FAQ, question 25 | EPA expressly permits commercial use of eGRID data; use its suggested release-specific citation. |
| ECHO Facility Registry links | EPA distribution metadata | The exact frs_downloads.zip distribution is assigned the EPA data license. |
| ECHO ICIS-Air | EPA distribution metadata | The exact ICIS-AIR_downloads.zip distribution is assigned the EPA data license. |
| ECHO ICIS-NPDES | EPA distribution metadata | The exact npdes_downloads.zip distribution is assigned the EPA data license. |
| ECHO RCRAInfo | EPA distribution metadata | The exact rcra_downloads.zip distribution is assigned the EPA data license. |
| ECHO federal enforcement | EPA distribution metadata | The exact case_downloads.zip distribution is assigned the EPA data license; linked documents require separate consideration. |
| CAMPD accounts, allowance/compliance files and monthly emissions | CAM API portal and EPA data policy | Public structured-data access; program/default rights evidence, not a separately verified commercial grant for every endpoint or submission. |
| ECMPS monitoring plans and QA/certification | EPA public reporting access and EPA data policy | Public structured records only; private workspaces and third-party narrative rights are not included. |
| ECHO combined air emissions and CAA pipeline | ECHO downloads and EPA data policy | Program/default policy evidence; no separate exact-file commercial grant established in the review. |
| GHGRP facility, crosswalk and unit/fuel data | GHGRP datasets, citation guidance and EPA data policy | Identify GHGRP, resource and access date. Citation guidance alone is not a license; rights in submitted expressive material require review. |
| NEI facility/process inventory | Official download page and EPA data policy | Retain NEI version and limitations; program/default policy evidence, not blanket permission for third-party documents. |
Limits and delivery notices
The EPA data policy identifies EPA-produced data as United States public domain unless otherwise specified and directs users to dataset metadata. EPA's document disclaimer warns that individual documents may have different copyright conditions. Public availability alone does not resolve rights in third-party material.
For conditional sources above, the relevant rights must be verified for the actual material before inclusion in a commercial export. This register does not imply that unresolved rights have been cleared or that a commercial redistribution right exists merely because BaseloadOS holds a copy. No proprietary source rights are waived by a customer's payment.
Each delivered manifest must identify included sources and releases, retrieval or snapshot information, applicable attribution and licenses, and modifications. Mandatory source notices travel with redistributed material. Nothing in BaseloadOS terms narrows independently held public-domain or open-license rights, grants an agency logo license, or implies agency endorsement.
