Water shall not be impounded in the Spec Agg <br /> Quarry Pit except pursuant to lawful diversions allowed by statute or decree. At all other times, Martin Marietta <br /> or their successor has the responsibility to ensure that all inflow of water into the pit from any source, including- <br /> precipitation and ground water inflows is removed to prevent any out-of-priority storage of water or secure a <br /> Water Court approved augmentation plan or State Engineer approved substitute water supply plan to replace <br /> such out-of-priority storage.
