Resources

Official CBYD tools, guides, and reference materials to support safe excavation and compliance in Connecticut.

State Laws & Regulations

Connecticut law requires contacting CBYD prior to excavation involving mechanized or powered equipment. These laws exist to protect underground utility infrastructure and, most importantly, the people working around it.

Connecticut’s Call Before You Dig (CBYD) program is effective, free, and required by law. Excavators and permit-issuing agencies share responsibility for compliance and public safety.

Important

On January 30, 2024, the Public Utilities Regulatory Authority (PURA) issued a memo to all excavation permit-issuing agencies in Connecticut clarifying responsibilities under state law.
