Pitch Reclamation Project 2005 Annual Reclamation April 14, 2006 Page 1 • 1.0 INTRODUCTION 3.1 Terms and Conditions AES~ Lynx Enterprises, Inc. (Lynx) was retained by Homestake to collect the data from contractors engaged at the Pitch Reclamation Project and assemble this report of the 2005 monitoring and reclamation activities. Data for this report was provided by: Lynx, SRK, Inc., Energy Laboratories, Inc., hand the Homestake-Pitch Project field office in Sargents, Colorado. 3.1 Purpose and Scope of Work This report was prepared to fulfill the annual reclamation reporting requirements of Homestake to the Colorado Division of Minerals and Geology for reclamation permit number M-77-004. This report primarily presents reclamation and monitoring conducted during the 2005 calendar year. Documentation of reclamation conducted in previous years was presented in prior annual reports. 1.3 Project Description The Pitch Reclamation Project is located in Township 48 North, Range 6 East, Saguache County, Colorado. The project area is located in the Gunnison National Forest. The primary drainage from the property is Indian Creek. Drainage from Tie Camp Creek joins Indian Creek upstream of the CDPHE discharge monitoring point at the project site. Indian Creek joins Marshall Creek approximately four miles southwest of the Pitch property. A site location map is provided as Figure 1. • 2.OI LAND DISTURBED /N 2005 Surface disturbance in 2005 was limited to work associated with the site improvements in the former area of the Radium Treatment Plant (RTP), and the final physical reclamation work performed on the disposal cell located at the toe of the Tie Camp Creek Low-Grade Ore Stockpile. These activities occurred on ground already disturbed by project related facilities. No new land disturbance occurred at the Pitch Reclamation Project during 2005. RECLAMATION ACTIVITIES /N 2005 g 2005, reclamation activities at the Pitch site focused on two primary areas: 1) the area ent to the dismantled RTP (including the stream channel) and, 2) the Tie Camp Creek Disposal All work was conducted in accordance with applicable conditions in the Radioactive Materials se and the Pitch Reclamation Project Procedures Manual. 3.1 Reclamation i Reclamation activities in 2005 consisted of drainage Improvements in the area of the old RTP building and the adjacent drainage. The former site of the RTP was backfilled and recontoured in 20011, with grading and initial revegetation in 2002. These activities included the steep embankment behind the former RTP site, where the area was graded to reduce the slope and prevent sloughing. Reclamation in the area has included measures to control sedimentation and to stabilize the slope adjacent to and down gradient from the site, including construction of small dikes in the drainage to allow the creation of small catch basins followed by the placement of timber slash in the drainage to • retard flow velocity and to trap sediment. Since 2002, stabilization measures have included planting of 1 000 lodge pole pines, and 200 spruce trees on the contoured area and planting of 500 lodge pole pine and 200 douglas fir seedlings on the slope opposite the former RTP building site.
