| Spill Description: |
| During surface casing drilling operations at the Hunziker 1N-4HZ well, the valve alignment for the mud pumps/mud tanks were setup improperly causing water-based drilling fluid to overflow from a secondary tank onto the ground surface. Approximately 9 bbls of water-based drilling fluid were released onto the ground surface of the bermed well pad. A hydro-vac truck was used to recover approximately 9 bbls of the released water-based drilling fluid and return it to the active mud system. Confirmation soil samples were collected from the release area and the analytical results and excavation details are provided below. A topographic Site Location Map showing the general location of the release is attached as Figure 1. |
