CalEPA (California Environmental Protection Agency) is the California state equivalent to the United States EPA. The Agency oversees the Air Resources Board, the Department of Resources Recycling and Recovery (CalRecycle), the Department of Pesticide Regulation, the Department of Toxic Substances Control, the Office of Environmental Health Hazard Assessment, and the State Water Resources Board.
The California Code of Regulations contains the environmental regulations passed by the state of California. The state code can also be accessed in print on Level 2 of the Law Library, at the LA County Law Library, and at other area state depository libraries.

These compiled surveys of state laws and regulations focus on specific areas of law including many environmental issues such as implementation of the Federal Clean Air Act or Federal Clear Water Act. A 50-State Survey is helpful when seeking an overview of the laws of multiple states. These can be located through the UCLA Law Library Catalog, LexisAdvance, WestlawNext, and HeinOnline.
Law schools throughout the United States and abroad often compile research guides much like this one, but tailored to their state resources. To locate these research guides, run a search in Google (ex. [state name] environmental law research guide).
