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

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.

Perimeter Controls Presentation

I am giving a presentation on Perimeter Controls: Non-standard Practices for Managing Water and Sediment today at noon. Go to Erosion and Sediment Control Association- British Columbia for information and to sign up. It’s only 10 bucks.

Description-Silt fence is not the only perimeter control BMP option. It is not the best option in many situations. In this presentation, I will discuss when silt fence makes sense, when it doesn’t, what other options are available.

Steel Plates Trackout

Trackout happens when you back trucks off of the steel plates onto dirt to unload materials. The plan was for trucks to stay on plates, back to the end and dump. The excavator was to move the materials around the site. There is no tire wash on this project as there isn’t room, so staying on the plates is required and necessary. The trackout is onto the neighbors parking lot, our only site access, and they don’t appreciate dirt ending up in their stormwater swale when the rains come.

Windy, Dusty, No Water

It’s windy, dusty and there is no water. Wait! Hey man, there is a hydrant right there. Use it, spray the dirt, keep the dust down!

Boulder Fence Silt Fence

I like boulder fence but I hate silt fence. I hate that it is plastic and not recyclable and that it ends up in the land fill. However, it is very strong and in this instance it is the right BMP.
