1.0 INTRODUCTION Section 4.3 in Permit No. C-80-001 requires an annual erosion inventory of the permanently reclaimed lands that remain under bond at Pittsburg & Midway Coal Mining Company's (P&M Coal), Edna Mine. The 2005 erosion inventory was conducted by WWC Engineering on June 7, 2005. WWC Engineering contracted with M. J. Miller, Inc. to complete the repairs determined necessary during the erosion inventory. A description of the 2005 inventory results and scheduled repairs are presented below. The permit requires that an Annual Erosion Inventory Report be submitted to the CDMG on or before July 15 of each yeaz. As agreed during a telephone conversation between P&M Coal and CDMG, the 2005 Annual Erosion Inventory Report is being submitted on or before September 15, 2005. 1.1 Erosion Inventory Background The first erosion inventory was performed in the spring of 1992 after the initial permit approval. The spring 1992 survey included the South-of--Shop areas. The second inventory was conducted in the fall of 1992. The two inventories conducted in 1992 were included in the 1993 report. The third inventory was conducted in the fall of 1993 for the 1994 report. Further changes in the permit language resulted in the inventories being performed in the spring of each year, starting with the 1995 annual erosion inventory. Erosion inventory summary data for the last ten yeazs, 1996 through 2005, is included in this report. 1.2 Scope of 2005 Erosion Inventory The Moffat Area and the West Ridge are the only permanently reclaimed areas that aze currently required to be inventoried (Exhibit 1, sheets 1 and 2). The South of Shop area was released from bond in 1999 and is no longer inventoried. In August 2003, the Goat Trail Area was released from bond. Therefore, monitoring of concentrated flow features and the C-Building hill slope azea is no longer inventoried. 1.2.1 Moffat Area Inventory A total of 10 blocks are included in the Moffat Area monitoring plan (Exhibit 1, Sheet 1). Initial monitoring of portions of the Moffat Area began in 1992 as reclamation activities were completed on various blocks. Block 10 of the Moffat Area was added to the inventory in 1997 as a result of completing reclamation activities on the area during the fall of 1996. 1.2.2 West Ridge Inventory The West Ridge area is divided into a total of nine (9) blocks (Exhibit 1, sheets 1 & 2). The blocks have been named in reference to the terraces that bracket the block. For example, Block 1 - 6 is located between terraces T1 and T6. The West Ridge area was incorporated into the inventory after the completion of the terraces in late 1995.
