The work plan should also outline the transport methods and ultimate destination for excavated lime. Lime may also be stockpiled on site for later use as fill material. Transport methods may include but are not limited to a transfer truck (i.e., a dump truck,tank truck, or vacuum truckl, a roll-off bin, a frac tank, or a railcar. 8.2.5 Environmental controls Best management practices to control storm water runoff, dust emissions, noise, and accidental releases (such as a response plan for potential lime spills during transportation) should be identified in this element of the plan. 8.2.6 Sampling and analysis plan If any additional sampling and analysis is necessary, this element of the work plan should include a description of the number and location of samples taken and the sampling and analytical methods used. 8.2.7 Site restoration This element of the work plan details on-site restoration activities and should describe: • amount and type of clean backfill material imported and backfill placement and compaction requirements; • mixing methods for residual lime; and • site restoration, grading, and cover material. 8.2.8 Project schedule The work plan should include a detailed schedule of lime pond closure activities.A timeline or Gantt chart format is often very helpful. 8.2.9 Health, safety, and security plan A site-specific health and safety plan should be prepared to address health and safety issues associated with carbide lime and other potential hazards.
