Policy & Guidance

The EPA has primary responsibility for enforcing many of the environmental statutes and regulations of the United States. As such, the Agency is grantedexplicit enforcement authority in environmental statutes. Sometimes, however, that authority needs to be further refined or explained. In such cases, EPA may develop and implement policies and write guidance. In addition, EPA sometimes issues policy or guidance to encourage compliance with environmental requirements.

Policy documents represent EPA's official interpretation or view of specific issues. Guidance documents are published to further clarify regulations and to assist in implementation of environmental regulations.
