Sec.  61.25  Recordkeeping requirements.



    The owner or operator of a mine must maintain records documenting 

the source of input parameters including the results of all measurements 

upon which they are based, the calculations and/or analytical methods 

used to derive values for input parameters, and the procedure used to 

determine compliance. In addition, the documentation should be 

sufficient to allow an independent auditor to verify the accuracy of the 

determination made concerning the facility's compliance with the 

standard. These records must be kept at the mine or by the owner or 

operator for at least five years and upon request be made available for 

inspection by the Administrator, or his authorized representative.
