Silt Fence Here?

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.

Gas Can in Trash Can

Does this gas can in a trash can meet the requirements of secondary containment? I would say yes because the trash can has more volume than the gas can.

Dusty Spalls

Dusty Spalls-sounds like the name of a cowboy in an old “B” western film. These quarry spalls came with enough crushed rock dust to create a fugitive dust cloud when dropped into a “skip” box.

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.

Small Oil Spill

I usually require a contractor to clean up a small oil spill like this. We will remove all of the soil on this project and dispose it as mildly contaminated; I let it go this time.

Stay on the Plates

Video: David Jenkins-Sheetflow Erosion Control

Please stay on the steel plates! We are using steel plates for a construction access to this long, narrow site. We exit onto the parking lot of an adjacent company. Sediment trackout is not an option. There is no place to install a tire wash, which I would normally require on a project like this. This requires a lot of oversight to work and one of the things we expect is for trucks to stay on the plates so they don’t pick up any dirt on the tires. This driver didn’t get the message, and the excavator operator could have beeped to stop the driver from backing too far.
