d. Proposed date of recovery
e. Proposed water table recovery elevations
Reporting required under 1) and 2) above associated with piezometers that deviated from the internal or
external thresholds described in Section 6.0 will occur monthly until the piezometer water level has been
restored to a level above the seasonally appropriate P50 value, consistent with Section 8.0 above.
Monthly reports will recommence if an external trigger is again exceeded.
Mosaic will submit a Semi-Annual Report to the District for all areas when any Mine Activities are
conducted within the MMD. Reports will be submitted on November 15th of each year for the preceding
June 1 through September 30 period of 4 months, and July 15th for the preceding October 1 through May
31 period of 8 months. The Semi-Annual Report will identify all instances where the SAS water levels
measured below the internal and external triggers in all monitored systems, and provide detailed
evaluations as to the cause of the hydrologic disturbance, including:
1) The mine history within the MMD of the site of the SAS water level disturbance
2) The rainfall record at the nearest rain gage
3) If a relationship to Mine Activities is determined, details of corrective measures taken, the
extent of recovery in SAS water levels , and a thorough discussion of methods to be used in
the future to prevent similar hydrologic disturbances
Mosaic will submit an Annual Report to the District with the following information:
1) Current aerial photos of all active mining/dewatering sites and all monitoring points located
and identified on the aerials
2) Period of record monitoring data (electronic) for all sites identified on the aerials,
3) Summaries/analyses of the previous year’s monitoring data, Mine Activities, and weather
The Annual Report will also identify any instances of SAS water levels measured below the internal and
external thresholds in all monitored systems and provide detailed evaluations as to the cause of any
Adverse Impacts that are a result of Mine Activities, including:
4) The mine history within the MMD of the locations of Adverse Impacts to SAS water levels, if
any.
5) The rainfall record at the nearest rain gage.
6) Determination and discussion as to water table level deviation from historic ranges and
relationship to Mine Activities
7) If causation for any documented SAS water level deviations from historic ranges are
attributed to Mine Activities, then Mosaic must specify the corrective actions taken, the results
of such actions, and a thorough assessment of any appropriate preventative measures to be
taken in the future.
8) Summaries of all functional assessments and wetland mitigation for the previous year as
required by Section 9.0.
