Laws and Regulations Services

Laws and Regulations Services (LRS) is a publicly available web service that provides a catalog of environmental laws and regulations and associated data. LRS is a component of the EPA's System of Registries. LRS associates law and regulation data with keywords, NAICS codes, EPA programs and offices, and substance lists from the Substance Registry Service (SRS). Laws and regulation data in LRS is extracted from the Code of Federal Regulations (CFR), published by the Government Publishing Office (GPO).
