This letter serves to fulfill the abatement actions required as follows: Steps necessary to abate violation (remedial action): Provide all available missing data The approved permit requires reporting of the flow volume and results of a single sample collected during the annual spring and seep survey from springs and seeps with a discharge volume greater than 20 gpm. The discharge from these springs is to be analyzed for the complete list of pazameters used for surface water monitoring sites, except TSS, as provided in Table 4.6-54, page 4.6-144, of the permit. Springs and seeps with discharge volumes less than 20 gpm but having sufficient concentrated flow to be sampled are to have the flow volume visually estimated and tested for certain field pazameters (page 4.6-146). The only data available regazding springs and seeps at the Edna Mine coincident with the May 1994 spring and seep survey is from Spring #1 (this spring is also designated as NPDES discharge point 006). Attached is a copy of the NPDES report for the month of May, 1994. While this report does not contain results for all of the parameters listed in Table 4.6-54 of the permit, it does provide analyses for some of the parameters including flow, pH, sulfate, iron and manganese. Provide a written explanation as to why the spoil spring monitoring program was not completed as required by the approved permit. The only spring or seep located during the 1994 spring and seep survey at the Edna Mine with a discharge greater than 20 gpm was spring # 1 (NPDES 006). Due [o an internal miscommunication within P&M, the individual(s) who performed the survey were not aware
