• EXHIBIT D MINING PLAN A . Description of Methods of Mining For each pit open pit mining is or will be employed. Equipment used in the mining operation consists of a HD 16 Dozer with ripper, Dragline , and Wheel Loaders . The Loaders are used 90% of the time, due to existing waste stockpiles left from mining prior to commencement of the Headley opera- tion. As the waste material is removed, a paddle scraper removes the remaining gravel to existing topsoil and levels the area so that it will be available for irrigation and replanting to a nurse crop, either barley or rye, and new seeding hay . Approximately fifteen (15) acres have already been reclaimed by Applicant on the area mined prior to 1976 . In those pits where water has been induced pursuant to Applicant' s water rights plan, a clam shell or dragline has been used to excavate the gravel . B. Earth Moving Overburden in this area is a very sandy soil with a • binding agent. This soil was removed and used in construction of the dams for the three reservoirs shown in Exhibit C. There are no spoil piles . The equipment used was scrapers and some bottom dump trucks . Since the commencement of the Headley operations , any overburden removed has been placed on the land being reclaimed, a practice which will continue as Applicant initiates and continues the reclamation plan. C. Diversions or Impoundments No water diversions or impoundments are made for the express purpose of the gravel operation. Normally a dry operation, the aggregate needs no washing to meet usual specifications . However, water is introduced to the gravel pits in conjunction with Mr . Headley' s water rights plan as infiltration points for his underground storage . The three dams which are shown in Exhibit C were constructed not for the purpose of the gravel operation but to provide storage and infiltration for the water rights and subsequent irriga- tion of Mr . Headley' s crops . Except after severe rain storms , no waters escape the Headley property on the surface . (See also Exhibit G)
