The plan shall identify potential sources of pollution (including sedimenQ which may reasonably be <br />expected to affect the quality of stormwa[er discharges associated with the mining operation. In addition, the plan shall <br />describe and ensure the implementation of best management practices (BMPs) which will be used to reduce the pollutants <br />in stormwa[er discharges associazed with mining activity and to assure compliance with the terms and conditions of this <br />permit. <br />Permittees must implement the provisions of their SWMP as a condition of this permit.
