Conn. Agencies Regs. § 13b-17-5
When it appears that the work called for in an application would cause substantial or needless damage to a highway, create excessive disturbance to traffic or result in dangerous conditions, or is detrimental to the aesthetics of the highway, the request for a permit will be denied. The applicant will be informed of such denial by letter from the District Maintenance Manager which will state the results of the investigation and the reason for the denial. The District Maintenance Manager may refuse to issue a permit to any person, company or municipality when work performed under a previously issued permit was not properly executed, or when said applicant has failed to reimburse the State for recoverable charges billed under the terms governing a previous permit.
