1.20 BMP C152 - Sawcutting and Surfacing Pollution Prevention
Sawcutting and surfacing operations generate slurry and process water that contains fine particles and high pH (concrete cutting), both of which can violate water quality standards in the receiving water. This BMP is intended to minimize and eliminate process water and slurry from entering waters of the State
Anytime sawcutting or surfacing operations take place, use these management practices. Sawcutting and surfacing operations include, but are not limited to, the following:
1.20.3 Design and Installation Specifications
Vacuum slurry and cuttings during cutting and surfacing operations.
Do not leave slurry and cuttings on permanent concrete or asphalt pavement overnight.
Do not allow slurry and cuttings to enter any natural or constructed conveyance system.
Dispose of collected slurry and cuttings in a manner that does not violate groundwater or surface water quality standards.
Do not allow process water that is generated during hydro-demolition, surface roughening, or similar operations to enter any natural or constructed conveyance system. Dispose of process water in a manner that does not violate groundwater or surface water quality standards.
Handle and dispose of cleaning waste material and demolition debris in a manner that does not cause contamination of water. If the area is swept with a pick-up sweeper, haul the material out of the area to an appropriate disposal site.
Continually monitor operations to determine whether slurry, cuttings, or process water could enter waters of the state. If inspections show that a violation of water quality standards could occur, stop operations and immediately implement preventive measures such as berms, barriers, secondary containment, and vacuum trucks.
