Now featuring Colorado oil & gas

State and federal regulations — searchable, cross-referenced, and easier to understand.

EssentialRegs brings Colorado oil and gas regulations, General Permits, federal EPA standards, and PHMSA pipeline requirements into one searchable reader. Whether you manage compliance, advise clients, operate a facility, or want to understand activities near your home or land, you can find relevant provisions, follow related requirements, and read the rules in context.

Clearly labeled plain-English summaries help you get oriented quickly, while links to official sources let you check the underlying regulatory text.

Spend less time finding rules, handle routine research yourself, and make more of the time you spend with a consultant.
