Would I put silt fence here? I would not. The work involves installing an 8 inch ductile water line to a property up the hill. The connection to service is at the left orange cone. The other orange cones are located on the backfilled excavation. I would have specified a gravel berm, asphalt berm, burlap fence, orange construction fence, or a combination.

Silt Fence Inspection
This silt fence looks pretty ugly and inspection shows it certainly needs maintenance; but does it? The silt fence made sense before we excavated several feet, now it doesn’t. There is a turbidity curtain in the river to the right and the contractor is careful to pull material back from the riverbank. I am going to let this go.

Temporary Boot Wash
We were excavating a riverbank next to a former Superfund cleanup site and we hit a layer of black soil. I stopped the work and called out an Environmental Agent (EA). The EA took samples of the soil and sent them to a lab for analysis. I had the contractor rope off the area and build a temporary boot wash at the site entrance. It turned out the soil was clean.

Construction Erosion Inspection-Trench Excavation Asphalt Kept Clean
Dirt from trench excavation loaded into front loader bucket and hauled to stockpile, or dirt side cast onto asphalt: which is cheaper? How about no sweeper needed, no dirty water going down the drain, asphalt kept clean? I go with the first answer.

Excavation for Conduit-Dirt On Wrong Side
It looks to me that the dirt might be on the wrong side. Or maybe not, as it keeps the runoff out and saves grass from being covered with dirt. It should be covered with plastic.

Construction Stormwater General Permit
Construction Stormwater General Permit
Construction site operators are required to be covered by a Construction Stormwater General Permit if they are engaged in clearing, grading, and excavating activities that disturb one or more acres and discharge stormwater to surface waters of the state. Smaller sites may also require coverage if they are part of a larger common plan of development that will ultimately disturb one acre or more. Operators of regulated construction sites are required to:
- Develop stormwater pollution prevention plans.
- Implement sediment, erosion, and pollution prevention control measures.
- Obtain coverage under this permit.
