CHAPTER 11

Waste Management Best Management Practices (10)

W aste management consists of implementing procedural and structural BMPs for handling, storing, and disposing of construction materials and wastes generated by the project to prevent the release from the site of construction or waste materials via airborne or storm water discharges.

WM-1 Material Delivery and Storage —All material delivery and storage (WM-1) areas must be noted in the water pollution control drawings. Update the water pollution control drawings as often as new changes are made or removed and at least monthly by default. The WM-1s must have perimeter sediment control BMPs (usually fiber rolls or silt fence) and, if necessary, environmentally sensitive area fencing to delineate inactive project areas from project active construction areas. The storage site must also be protected from run-on water, if applicable, from any area up gradient of the site. The WM-1 area is usually considered an active or disturbed soil area unless entirely on asphalt, concrete, or other impervious surface. Many WM-1s have TC-2 or TC-1 stabilized construction roadway or temporary construction entry/exit BMPs installed. There should be no material or sediment tracking from the WM-1 area.

In most project special provisions, when hazardous materials are delivered and consequently stored at a project delivery site, the material delivery itself must be inspected, and the site storage area should be inspected daily while hazardous materials are present. The person receiving the hazardous materials should be trained in hazardous material handling and spill prevention and control .

Many WM-1 storage areas are a target-rich environment for deficiencies due to the multifaceted nature of the materials stored there. There is often hazardous waste, solid waste, fuel and fluids for equipment, and hazardous construction fluids and chemicals present, as well as construction vehicles and equipment. Oftentimes there are stockpiles at the WM-1 areas. All stockpile areas are also to be noted on the water pollution control drawings, even if the stockpiles are within the boundary of the WM-1. Stockpiles must be protected per WM-3 Stockpile Management storm water management plan (SWMP) specifications, which will be reviewed shortly under WM-3.

Hazardous waste and non-waste fluids must be stored in watertight secondary containment. A conex storage container with a wooden floor is not a secondary containment apparatus. If a five-gallon bucket of oil or paint spills near the door of the storage trailer, the fluid will escape into the soil or whatever surface the storage container is on, or the spilled fluid will be tracked by foot traffic outside the storage area. In short, the fluids are not contained. Many times I have seen the flooring of these storage containers rotten or broken, allowing construction fluids to leak out of the container into the soil. Oftentimes the roofs leak and allow storm water to enter the storage area. This can allow saturation of the wood flooring, leading to eventual failure of the structural integrity of the floor, and create opportunity for fugitive materials to enter the soil under the storage area. I have seen oil saturation of wooden floors to where the oil actually penetrates the wood and drips into the soil under the storage area.
