Conn. Agencies Regs. § 13b-17-8
Except in instances where public service companies have filed a statement of solvency acceptable to the Secretary of the State, pursuant to the General Statutes, it is the responsibility of the District Maintenance Manager to determine who shall furnish the permit bond and the amount of the guarantee to be provided to the State in connection with each permit, after receiving a report on the proposed work from the Permit Investigator. The District Maintenance Manager shall specify that a permit bond in a definite amount shall be delivered to his/her office before a permit is issued. The permit bond shall remain in effect for a sufficient period after the completion of construction to insure the repair of any work which has settled, eroded or deteriorated. The bond may be released after this waiting period upon request in writing. The permit bond requirements may be waived for permits issued to municipalities when the work covered by the permit is to be performed by municipal forces.
With the exception mentioned herein, the amount of the permit bond shall be established separately for each permit so that the State will be protected against loss in the event of the failure of the permit holder to complete the work or make required repairs or restorations involving the work or encroachment authorized by the permit. Immediately upon the approval of an application for permit, the District Maintenance Manager will advise the applicant of the amount of the permit bond required. On major utility projects such as new sewer and water main installations the permit bond amount shall be established during the plan review stage of the project. An annual blanket permit bond, acceptable to the Department, may be deposited to avoid the inconvenience and expense of obtaining individual bonds for each permit requested.
