(a) For purposes of this section: (1) "Excavation Ticket" means a notification provided by an excavator to the central clearinghouse, as defined in section 16-345(4) of the Connecticut General Statutes. (2) "Markout" means the process of marking the approximate location of an underground facility on the surface with paint, flags or stakes pursuant to section 16-345-5 of the Regulations of Connecticut State Agencies. (b) The actions required by section 16-345-3(b) of the Regulations of Connecticut State Agencies shall not be performed by contractors. (c) Each Operator shall define the limits of blasting near such Operator's Pipeline Facilities including: (1) setting limits on the peak particle velocity based on Pipe material, Pipe size and geologic conditions; (2) requiring monitoring of peak particle velocity utilizing appropriate equipment to ensure that the maximum peak particle velocity is not exceeded; and (3) conducting a leakage survey at the end of each blasting sequence for a distance considered adequate to ensure the integrity of the Pipeline Facilities. (d) Each Operator shall have a program to inspect excavation activities in the vicinity of such Operator's Pipeline Facilities that includes: (1) for each calendar year, performing a number of inspections at least equal to 2.5 percent of the previous calendar year's number of Excavation Tickets received; (2) not more than 25 percent of the inspections on excavations performed by the Operator or by contractors working for the Operator; (3) inspections only being conducted by individuals other than those who performed the Markout; and (4) the risk-based selection of inspections, considering the type and duration of excavation activity, the proximity to Pipeline Facilities, the proximity to critical facilities, and the past experience with the excavator.
