Section XV-2721 - Surface-Water Monitoring Plan

A. The application shall include a surface-water monitoring plan based upon the PHC determination required under §2523 and the analysis of all baseline hydrologic, geologic, and other information in the permit application. The plan shall provide for the monitoring of parameters that relate to the suitability of the surface water for current and approved post-mined land uses and to the objectives for protection of the hydrologic balance as set forth in §2717, as well as the effluent limitations found at 40 CFR Part 434.

B. The plan shall identify the surface-water quantity and quality parameters to be monitored, sampling frequency and site locations. It shall describe how the data may be used to determine the impacts of the operation upon the hydrologic balance.

1. At all monitoring locations in the surface-water bodies such as streams, lakes and impoundments that are potentially impacted or into which water will be discharged and at upstream monitoring locations, the total dissolved solids or specific conductance corrected to 25 C, total suspended solids, pH, total iron, total manganese and flow shall be monitored.

2. For point-source discharges, monitoring shall be conducted in accordance with 40 CFR Parts 122, 123 and 434 and as required by the National Pollutant Discharge Elimination System permitting authority.

C. The monitoring reports shall be submitted to the office every three months. The office may require additional monitoring.
