Laws and Regulations Services

LRS is a catalog of laws relevant to EPA, the regulations that implement those laws, and the EPA programs that oversee those regulations.

  • The statutory and regulatory information is gleaned from the Code of Federal Regulations (CFR), published annually by the Government Publishing Office (GPO);
  • LRS provides links to the GPO websites that are the official sources for the United States Code and the CFR.

LRS identifies how EPA manages the laws and regulations for which it is responsible and is an important resource for EPA's information management.

Through integration with other registries and enterprise resources, users can discover potentially applicable regulations by searching:

  • chemicals or substances
  • North American Industrial Classification System (NAICS) codes
  • keywords
  • industrial processes

By linking these data, regulated entities can begin getting a better picture of what their regulatory responsibilities might be. This information is key to compliance assistance efforts. It is also useful to EPA inspectors, who need to be able to quickly look up regulations while they're in the field.

LRS data is available via a web service.

  • Currently, the service can call laws, regulations, EPA programs, and chemicals associated with regulations.
  • In the near future, the service will be modified to include the ability to call data based on associated NAICS code and keyword as well.

Future Plans:

EPA is currently working on mapping processes (i.e., aircraft fuselage welding) to the applicable NAICS codes, as many regulations list processes rather than NAICS codes in their text.

EPA realizes the benefit of connecting all of this data not only to federal laws and regulations, but to state and tribal laws and regulations as well. EPA hopes to undertake this challenging task with its state and tribal partners; EPA is exploring this mapping with a few partners, and then developing a plan for how to connect all of the data together.
