The Tin Pan Canyon Gob Reclamation Project area is located about eight miles northwest of Ratonin Colfax County, New Mexico. The project area (see Figure 1, referred to hereafter as “Site”) is on private land within the Vermejo Park Ranch (“Ranch”).  A mandatory pre-bid conference is set for May 5, 2020 and bids open on May 19, 2020.

The Tin Pan Gob Reclamation Project involves stabilization of steep slopes on two coal gob piles approximately two acres in size that have been contributing mine waste to an adjacent ephemeral channel.  Work includes establishment of vegetation and installation of various erosion control structures necessary to facilitate effective stormwater management. 

The Contractor shall complete the following tasks:

  • installation of a rock rundown to further prevent headcuts at the downstream edge of the access road from moving into the road. The rock rundown has been designed by Natural Channel Design.  Technical specifications and design drawings for the rock rundown are shown in ATTACHMENT A;
  • installation of erosion control wattles and straw bale terraces on contour on the gob piles and sediment logs in small gob drainages as erosion and sediment control measures (Vermejo Park Ranch will furnish the erosion control wattles to be used for this project);
  • installation of several low sediment barrier dams along the secondary drainage adjacent to the small north gob pile and at one small drainage below the larger south gob pile for sediment control; and
  • seedling planting, fertilization, amendment, and hydroseeding in coal gob piles to stabilize the coal waste and prevent future erosion.
