| TANK ABANDONMENT PROCEDURES |
| We will expose the top of the tank by hand. We will cut the top of the tank open to produce a hole approximately 2 wide by 4 long. |
|
|
| We will vacuum the tank of any free product as well as vacuum out sludge and residual oil. The interior of your tank will be pressure washed. |
|
|
| Confined Space Trained Technicians (CFR 291910.120 Certified) will enter the tank and cut the bottom of the tank open approximately 1 by 1 square for extraction of soil sample. |
|
|
| A soil sample will be collected from beneath the tank under Chain of Custody protocols and witnessed by local authorities. The soil sample will be analyzed on site using a PetroFlag® soil analysis kit and the original sample will be sent to a state certified lab to confirm our site findings. |
|
|
| Providing the soil sample has no evidence of oil impacts, the tank will be filled with an inert material (i.e. foam or sand). |
|
|
| When the tank is full with inert material, the panel that was cut off earlier will be replaced. |
|
|
| We will backfill over the top of the tank and compact the area to its original grade. We will issue a letter report summarizing the project and soil results. |
