Erosions and Sediment Control
Job planning will be conducted pre-job, during construction, and after construction. Pre-job meetings will be held to plan for the least amount of disturbance as necessary and what control measures need to be put into place. Job planning shall be conducted during construction to ensure that erosion and sediment control measures are in place and the procedures are being followed. Post-job planning shall be in place to ensure that temporary controls have been removed and that all potential problem areas have been addressed.
When clearing, stripping land, and excavating during construction activities the schedule will include a plan to minimize the amount of time that the bare soil is left exposed and to minimize the extent of soil exposure at any one time in order to reduce the amount of erosion and sedimentation that occurs.
When activities require a disturbance of the soil Mur-Cal will utilize erosion control devices as necessary to prevent erosion and ultimately to help prevent sedimentation. Examples of erosion control devices that may be used included: temporary seeding, temporary mulching, permanent sodding, erosion control blankets, and vegetative buffer strips.
Entry and exit points for any water runoff will be controlled with the use of sediment control devices to prevent sediment from entering any waterways. Commonly, storm drain inlets are protected to prevent sediment from entering the storm drain. Examples of sediment control devices that may be used include: silt fencing, straw bales, storm inlet traps, sediment ponds, rock check dams, and intercepting berms.
When erosion and sediment control devices are in use, Mur-Cal will l ensure that an inspection and maintenance plan is in place for these devices. A set inspection schedule should be established to view all areas where erosion and sediment control devices are used as well as all disturbed areas. Any erosion or sediment control devices that are found to be damaged or deficient during the inspection shall be corrected as soon as possible. Maintenance must also include removing sedimentation to prevent a breakthrough.
Mur-Cal employees that are responsible for erosion and sediment control devices must be competent in the design, installation, and maintenance of the devices. Training may be performed in-house or by a 3rd Party.
