Gas can on a pallet. If it’s out there, I will find it.

Water Line Break Part 2

Video: David Jenkins

In this Water Line Break Part 2 video, I show water management during the repair work including water diversion. The video cuts off before I can mention that all of the water is pumped to a tank for sediment settling then filtered and pumped into vegetation.

Turbidity 1-25-250 NTUs

Photo: David Jenkins

The sample on the left is just under 1 NTU, the middle is 25 NTUs, and the one on the right is 250 NTUs. In Washington state, the Construction Storm Water General NPDES Permit lists benchmarks that construction discharges must meet. These are: 0-25 NTUs everything is cool; 26 -249 NTUs not so good, upgrade your site best management practices (BMPs) and modify your SWPPP; 250 NTUs and above, call the Dept. of Ecology, upgrade BMPs, modify the SWPPP and monitor the water body that the project discharges to until you are in compliance.

Tire Wash Fail Part 2

Photo: David Jenkins

I took this photo of same project from a few posts ago, but at a different angle.

If this was my project, I would move the tire wash closer to the site exit, place asphalt treated base over the rock, and place construction fence or eco-blocks along the sides to prevent vehicles from dragging mud onto the exit.

Secondary Containment Fail

Photo: David Jenkins

I told the contractor and the contract specifies that all chemicals and gas-powered tools remain in secondary containment when not in use. So, either they aren’t telling all of the workers and sub-contractors, they aren’t inspecting their site, or maybe they don’t care.

Drive-by Silt Fence Inspection

Video: David Jenkins

It doesn’t take more than a few seconds during a drive-by inspection to see that this silt fence has problems. While the risk of sediment discharge is low, the condition of the fence says to me ” We don’t really think this TESC stuff is all that necessary.” If it was my job to inspect, I would be making a “U” turn to have a chat.
