Light Plant in Secondary Containment

The kiddy pool is placed under the motor and drip pan. If there are drips that cause a sheen while rain water is present, the sheen will be picked up with spill pads and the water tipped out onto the ground. The spill pads will be paced in a plastic bag and disposed of in the trash.

Kiddy Pools for Secondary Containment

Always a good idea to have kiddie pools on hand for all of your secondary containment needs.

Secondary Containment Fail

The contractor has been told 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.

Where’s the Gas Can?

On a construction erosion control “walk-through”, I just happened to look over and saw a red, round object. On close inspection it turned out to be a gas can full of gas. How it ended up here I never learned and I don’t know how they got it out but it wasn’t there for the next inspection a week later.

Tank Farm-Final Cleanup

Tank Farm Cleanup Photo: David Jenkins

There is nothing quite like the smell of oil-soaked soil on a hot summer day. This was the final cleanup of a World War 2 era oil and fuel tank farm. The project involved removing the tank bottoms, piping, and dirty soil. As this is located next to the bay, ground water levels are high. Because so much of the oil and fuel had drained to the groundwater table, we also had to build a large, deep containment wall to keep the floating oil in place during the tidal displacements so that we could slowly suck it up and dispose of it.

Failed Secondary Containment

Maybe this is a new BMP…self-draining, never needs maintenance.
