Section 13b-17-30 - Excavating and trenching

All excavating and trenching operations shall conform to the current regulations for excavations published by the United States Department of Labor, Occupational Safety and Health Administration.

The size of the excavation shall be kept as small as practicable to carry on the work. Excavated material shall be placed so as to interfere as little as possible with the ordinary use of the highway. Excavated material must not be placed in drainage ditches. Where there is a drainage structure in the vicinity of the excavation, the water in the trench shall be discharged into this structure. Contaminated or excessively muddy water shall not be allowed to flow in the gutter or enter the State drainage system. Where excavations in the shoulder area disturb earth berms, these berms shall be replaced and stabilized in a manner acceptable to the District Maintenance Manager. Water in trench must not be pumped onto the pavement or travelway. A sump hole and pump should be employed if water is present in the ditch or trench and cannot be stopped or diverted. The permittee is prohibited from opening more trench than can be closed in one day.
