Researching Environmental Law: Environmental Legal System

Environmental law can be referred to as "belt-and-suspenders" - it is comprised of a large number of laws and regulations that often overlap and cover a wide range of areas. For this reason, it is also referred to as its own system.

Over the past four decades, "Environmental Law" has evolved into a legal system of statutes, regulations, guidelines, requirements, policies, and case-specific judicial and administrative interpretations that address a wide-ranging set of environmental issues and concerns. 

- Environmental Law Handbook (Thomas F. P. Sullivan ed., 23d ed. 2017

There may be state and local environmental requirements in addition to federal laws. Federal law preempts state and local environmental law, but there can still be specific requirements of state agencies, and/or state agencies may carry out functions on behalf of a federal agency. It can cover different subjects in addition to traditional law, such as public safety, health, and science. It can include environmental protection and compliance, wetlands, pollution, toxic torts, air, water, public lands, etc. Add all of this to the complexity of understanding administrative law, practice, and procedure, and environmental law can be one of the most complicated subjects you will ever study.

The resources in this guide are designed to be a brief overview of the many different resources that are important in the study and practice of environmental law. It does not claim to be comprehensive but instead is designed to serve as a starting point. The laws listed on this page are available on Westlaw, Lexis Advance, and Fastcase for members of the Loyola community. Any additional links below are to other free/useful online or print sources.  

Some Relevant Laws and Regulations - Federal

The Parallel Table of Authorities and Rules lists rulemaking authority for provisions in the Code of Federal Regulations (CFR) by listing U.S.C. provisions next to corresponding CFR provisions. This is intended to show the wide range of legal materials in environmental law, not to be a comprehensive list. 

These citations are read as:

  • 42 U.S.C. 7401: Title 42, United States Code, section 7401
  • The CFR is cited in the same way - 40 CFR 8.8: Title 40, Code of Federal Regulations, section 8.8
