 The Oklahoma Partnership Approach to Reclamation of Abandoned Mine Land

The Oklahoma Partnership agreement was the first such "formal effort" in the nation to share personnel resources to accomplish abandoned mine land reclamation. Because of the success of the project, the Partnership was awarded the 1999 Office of Surface Mining Regional Abandoned Mine Land Reclamation Award. This joint effort demonstrated how effectively reclamation can occur in a timely manner through cooperation and sharing of personnel resources between USDA Natural Resources Conservation Service and State Abandoned Mine Land Programs. Several states have seen the advantages of this effort and have implemented similar partnerships.

The reclamation projects included designs being prepared by one agency, construction contracted by another agency, and construction inspection and technical support being provided by locally available technical personnel regardless of agency affiliation. This joint project involved reclamation of 36 acres of abandoned mine land on five separate properties in Rogers County, Oklahoma.

The Izett/Izett site was on the east side of a heavily traveled, paved county road. A highwall. paralleled the road with a water-filled pit below and was hazardous to vehicles as well as local residents. Approximately 600 feet of highwall was eliminated and approximately 8 acres were reclaimed. The following photograph is a close-up view of a portion of the highwall above the water-filled pit prior to reclamation.

The Izett/Payne site was immediately west with a highwall and water-filled pit on the edge of the same heavily traveled road as the Izett/Izett site. Reclamation activities on this site covered approximately 5 acres. Vegetation was planted on the Izett and Payne sites immediately after the final tillage operation and a good cover of tall fescue was obtained even before final inspection. This view is looking southwest after reclamation toward a large pond now used for fishing.

The Izett/McCollough and Izett/Dowty sites were located in opposite sides of a very steep, graveled county road that is the sole access to several rural residences. In this photo, a school bus is coming down the very steep road between these sites.

The McCollough part had a water-filled pit with a 40-foot highwall adjacent to the south side of the road. The Dowty part had a deep pit with a 40-foot highwall adjacent to the north side of the road. Reclamation of these sites moved the hazard approximately 100 feet each way from the road. Approximately 2.5 acres were reclaimed at these sites. Reclamation has been completed and the site sprigged to bermudagrass. The vehicle in this photograph is in the approximate location as the school bus in the previous picture.

The Hendrix project straddled a tributary to Little Dog Creek which eventually drains into Lake Claremore, the primary water supply to the Claremore area. The Hendrix site was the last site in the watershed identified as producing acid mine drainage. The other two sites had been reclaimed some years earlier. This photograph shows the drainage prior to reclamation.

The Hendrix site was mined prior to present day reclamation standards. After the mining, approximately 2,000 feet of highwall with water-filled pits below were left. The spoils were covered with topsoil and vegetation; however, severe erosion occurred resulting in bare spoil piles that produced acid mine drainage. The bare spoils were treated with lime and revegetated on the south side of the creek. On the north side, the water-filled pit was treated with hydrated lime to neutralize the water. Shown here is the pit being treated with a hydro-seeder.

 Upon neutralization, the water was discharged. After the pit was dewatered, it was filled with the spoils. As soon as the lime treatment and tillage were completed, vegetation was planted and the site was fenced. Livestock will be introduced when vegetative cover is adequate for grazing. Nearly 30 acres were reclaimed at the Hendrix project.

The Partnership demonstrated that a very aggressive time schedule could be met by combining projects that were planned and designed by two agencies into one procedure. Total cost of the reclamation was well below the original estimate and was completed ahead of schedule. The positive impacts were less administrative overhead, reduced construction costs, less technical support costs, and timely construction. Three hazardous highwalls and a source of acid mine drainage into the municipal water supply were eliminated.
