The County Drain impacted is known as the Miner Extension Drain between Mason Road and Wilkinson Road and the Miner Drain from Wilkinson Road north to King Road.

Two drainage tile pipes were observed on the south side of Mason Road that flow through a culvert under Mason Road and into the catch basin for an underground section of the County Drain. Oil staining was observed in one of the drainage tiles and oil stained vegetation and sheen were observed at the catch basin. The interior of the culvert connecting the drainage tile outfall and catch basin was observed to be stained with oil. Approximately 300 gallons of oil were estimated to have been released into the County Drain from an unknown source south of Mason Road.

Access from all property owners along the impacted section of the County Drain, hereafter referred to as drain, has been granted.
