Mined Land Reclamation Board August 10, 1981 Page 7 weed control measures may be implemented, but this is not expected to be more than a mere possibility . Tree planting will occur the first spring ( late April to late May) following grass seeding. Plains Cottonwood trees will be planted at intervals of about 30 feet to 40 feet along and above the lake slope. Russian Olive trees will be planted at intervals of 8 to 15 feet between the cottonwoods . Each tree will be given a heavy initial watering followed by a heavy watering biweekly until mid-June . The trees will be watered heavily in late September, and thereafter they will establish themselves on ground water sources. Contingency Plan for Industrial Site It is hoped that the industrial site will be developed immediately upon completion of mining and backfilling activities . However, in the event such development does not occur, a con- tingency plan is hereby submitted. The plan assumes that some kind of development will occur. The city road plan calls for a through road here, and the presence of sewer and gas lines indicates development has an excellent chance of occurring. In the event of development not beginning within one year of completion of mining and backfilling, the area will be planted with the following mixture of grasses and legume: Species Rate (Lbs PLS/acre)* Intermediate Wheatgrass 6 Fairway Crested Wheatgrass 3 Alfalfa, Ranger ( innoculated) 1 10 *Drilled rate; if broadcast , rates will be doubled. The area will be fertilized prior to seeding with 30 pounds per acre of nitrogen and 20 pounds per acre of phosphorous . Since this part of the site is not going to be revegetated to a final land use, but only stabilized, soil tests will not be taken because such precision in fertilization is not necessary . Technical Revision 3 The current reclamation bond of $11 ,900 is not adequate to cover the revisions in the mining plan. Final bank slope and setback reclamation cannot be totally completed in Excavation Areas 1 and 2 until the backfill operations in Excavation Areas 2 and 4 are
