Ms. Kerry Sullivan December 23, 1996 it Page 3 i :r r R "soiling and Revegetation (Refer to SMARA Section 2773(a), CCR Sections 3503(a)(1),(t),(g), 3704(c), 3705 3707(b),(d), 3711(a),(b),(c),(d),(e)) 7. The Department recommends that the reclamation plan develop and implement a revegetation test program to"demonstrate that the sediment basin fines can be reclaimed-for agricultural use. Tests should focus on the amounts and types of amendments, especially organic material, that will be incorporated into the silty clay material so that crops can be grown. For example, the original reclamation plan specifies that 500 pounds per acre of fertilizer will likely be required. The application rate should be determined through soils analysis of the sediment pond fines and test plots. 7 4 � 8. The revegetation plan proposes to mulch and seed pit slopes with a mixture of blando brome, rose clover, and annual rye grass. It is recommended that the straw mulch be a incorporated into the slopes using a sheep's roller foot or equivalent, followed by the seeding. Given the steepness of the slopes and substrate, it is also recommended that the reclamation plan demonstrate that proposed fill slopes can be revegetated as proposed. 9. The reclamation plan proposes to monitor revegetation for a period of five years. Revegetation monitoring should continue until performance standards are met. The revegetation program should'also include remedial measures to be implemented if reclamation to agricultural crops cannot be achieved. It is also recommended that a specific cover standard for the erosion control mix be provided in the reclamation plan. 'i 124ND CONSERVATION k " i The Department, in addition to administering SMARA, also monitors conversion and impacts to prime agricultural land. The reclamation plan may already address the following t comments which relate to prime agricultural land, however the Department provides the ' following comments to the project proponent for general information. Prime Agricultural Land The California Code of Regulations (Section 15000 et seq., Appendix G [y]) states that a project will normally have a significant effect on the environment if it converts prime agricultural land to non-agricultural use or impairs the agricultural productivity of prime agricultural land. In r order to quantify impacts on prime agricultural land, the DER could identify the location of prime agricultural land within the project site, the number of acres of prime land that will be developed for the project, and the number of acres expected to be reclaimed to prime land. f � II Agriculture Production Data and Economi, MultiFier F, To compare project alternatives, the following data on the agricultural character of the project area could be provided in the DEIR: A discussion of current and past agricultural use of the project area and data on types of crops grown, yields, and crop values. w
