| dc.description.abstract | The Oklahoma Department of Environmental Quality (DEQ) is responsible for enforcing environmental laws and regulations. Partnering with the DEQ has provided Sustainable Solutions with the opportunity to aid the City of Enid Municipal Landfill with its current erosion problem. Attention was directed to an erosion concern on the north facing slope. These concerns include sediment deposition at the base of the slope, potential trash exposure, rill formation, scarce vegetative growth, and contamination of the on-site stormwater pond. Some current low-cost solutions on existing landfills around the state have been ineffective in solving the erosion problem long-term. Previously at the City of Enid Municipal Landfill, sections of the north facing slope have been hydroseeded with an ADC machine, covered with mulch, and sprigged and seeded. Other landfill erosion control methods include layering straw and topsoil on the slopes. Many solutions have succeeded for a time, but the erosion problem persists. Therefore, more sustainable designs must be implemented in order to prevent detrimental impacts to the environment. The EPA requires certain standards to be maintained for the on-site stormwater pond, runoff, and groundwater. Enid's composting program operates on the premises of the landfill. Therefore, yard waste compost and mulch are available for use as soil amendments. A stormwater detention pond nearby could also be utilized for irrigation. If on-site resources are successfully utilized to control the erosion concerns, a similar design could be applied at other erosion-prone sites with the potential to incorporate sustainable local resources. | |
