Page 288 Section 4.06.4 (i) Areas where light traffic does not destroy existing vegetation or cause erosion; or (ii) areas where removal would result in needless damage to soil characteristics; or (iii) areas of construction of small structures such as power poles, signs or fence lines. (b) For the purposes of these regulations, t soil is defined as soil orizons on the surface prior to jni�n&t will support plant life. The depth of topsoil to a sa vd be determined from the site specific soils information required in 2.04.9 as approved by the Division. (3) Subsoil Segregation. The B horizon and portions of the C horizon, or other underlying layers demonstrated to have qualities for comparable root development shall be segregated and replaced as subsoil, only if the Division determines that such material is necessary to ensure soil productivity consistent with the approved postmining land use. (4) (a) Selected overburden materials may be substituted for, or used as a supplement to topsoil, if the Division determines that the resulting soil medium is equal to or more suitable for sustaining the vegetation than is the available topsoil and the resulting soil medium is the best available in the permit area to support revegetation. This determination shall be based on: (i) The results of chemical and physical analyses of overburden and topsoil. These analyses shall include thickness of soil horizons, total depth, texture, percent coarse fragments, areal extent of the different soils and materials, determinations of pH, net acidity or alkalinity, phosphorus, potassium, texture class, electrical conductivity, sodium absorption ratio, and other analyses as required by the Division. The Division may also require that results of field -site trials or greenhouse tests be used to demonstrate the feasibility of using these overburden materials. (ii) The trials and tests shall be conducted using standard procedures approved by the Division.
