Section 38-3-10 - Revegetation and Standards for Evaluating Vegetative Cover10.1. General Requirements. -- Each operator shall establish on all regraded areas and all other disturbed areas a diverse, effective and permanent vegetative cover of the same seasonal variety native to the area of disturbed land, or introduced species that are compatible with the approved postmining land use.10.2. Objective in Revegetation. -- The objective in revegetation is to quickly establish a vegetative cover on all disturbed areas to minimize erosion, provide economic benefits, and restore aesthetic appeal. Plants that will give a quick permanent cover and enrich the soil shall be given priority. A temporary or permanent cover should be established by the end of the first growing season, and a permanent cover by the end of the second growing season. All plants shall be considered a tool in achieving stabilization and an appropriate land use objective.10.3. Seeding and Planting. 10.3.a. Seasonal Feasibility. -- Appropriate vegetation shall be planted, seeded, aerial-seeded, or hydro-seeded in accordance with accepted agricultural and reforestation practices when the season is favorable for seed germination and plant survival, except as otherwise specified in this rule.10.3.b. Minesoil Characteristics. -- Quarrying of minerals and removal of overburden results in minesoil which varies greatly in fertility, acidity and stoniness. These three (3) characteristics, together with steepness of slope, shall be used in determining characterization for the purpose of establishing vegetation. Premining overburden sampling and analysis or previous experience and correlation data, shall be submitted with the quarrying and reclamation plan for all acid-producing overburden or minerals. The plan shall identify acid strata and provide planned handling and final placement for acid strata. Overburden analysis shall be in accordance with standard procedures outlined in Environmental Protection Agency Manual No. 600/2-78-054 (Field & Laboratory Methods Applicable to Overburdens and Minesoils), or other approved methods by the Department of Environmental Protection.10.3.c. Function of Temporary Cover Crops. -- On areas where excessive erosion is likely to occur, rapid establishment of vegetative cover shall be required. Seeding of annuals and biennials on such areas shall be considered as a means for achieving temporary vegetative cover only and not acceptable in the achievement of permanent cover. See Table Five.10.3.d. Development of Planting Plan. -- Planting plans shall be a part of the quarrying and reclamation plan. The plan, when appropriate, shall include the following information:10.3.d.1. Tests for minesoil acidity, expressed as pH, shall be taken at points distributed uniformly over the disturbed area. Minesoil tests may be made with accepted field indicators or other approved techniques. Minesoils with chemical characteristics that could restrict vegetation establishment and growth shall be analyzed by an approved soils laboratory;10.3.d.2. Treatment to neutralize acidity;10.3.d.3. Mechanical seed bed preparation;10.3.d.4. Rate and analysis of fertilization;10.3.d.5. Rates and types of mulch;10.3.d.6.

Maintenance schedule if appropriate.10.3.e. Concurrent Revegetation. -- Seeding shall be concurrent with the operation as quarrying and reclamation progresses. The final spring planting date shall be May fifteenth. The final fall planting date shall be September fifteenth. The Secretary may establish alternate final planting dates for the spring and fall planting seasons based upon weather or other conditions.10.3.f. Plant Material Selection and Treatment.10.3.f.1.
