The North Lake Oologah Phase was initiated after further field investigations by OCC and EPA revealed a significant number of abandoned leaking wells threatening waterways in areas that drain directly into Lake Oologah. These areas were not originally targeted as part of the previous three phases of the Lake Oologah Spill Project, but the severity of the threat and proximity to the lake and its tributaries prompted the OCC and EPA to initiate a comprehensive assessment and coordinate removal. The removal will entail the plugging and abandonment (P&A) of the wells as well as cleanup of affected areas. All activities will be conducted in coordination between the EPA, OCC, OERB, and any identified Potentially Responsible Party (PRP).
