The product independently selects and arranges factual federal environmental records: identifiers, short site names, addresses, dates, codes, reported measurements, units and qualifiers. Federal government-created works are outside U.S. copyright protection under 17 USC 105, https://www.copyright.gov/title17/92chap1.html#105. Facts are not protected expression, https://www.copyright.gov/help/faq/faq-protect.html. These bases permit commercial redistribution of the delivered factual tables; public access alone is not a blanket license for protected EPA-hosted content.

EPA's policy distinguishes government information from protected third-party content: https://www.epa.gov/web-policies-and-procedures/epa-disclaimers. No photos, narrative violation comments, attachments, map tiles, proprietary D&B data, personal contacts or third-party enrichment are delivered. Government source code descriptions remain attributed. No endorsement, warranty of source accuracy or current compliance is implied.
