Testing Procedures <br />• The entire surface area of the refuse pile will be considered on experimental <br />surface with various treatments to be applied. Within each treament area, <br />specific transect areas and photos points will be designated for the <br />monitoring analysis; these areas would be the research "plots" for the <br />duration of the project. <br />The side slopes (north, west and south) would have alternate bands of <br />application running up and`down the slope. Because of size limitations, the <br />west aspect would be considered the primary research slope for hydro versus <br />broadcast seed and mulch applications. Alternate bands would be hydro seeded, <br />mulched with grass fiber material and "tacked" with hydro equipment; the <br />adjacent band would be broad cast seeded, grass fiber mulch would be blown on <br />and tacked. 'Labor and materials costs would be kept for a price comparison <br />and each operation would use the latest available techniques. Access to the <br />side slopes form the top must be maintained for equipment circulation so that <br />prepartation of the top would be in a second phase. <br />Seeding and mulching should occur directly after soil placement to provide <br />immediate surface stabiization from wind and rain impacts. Seed and mulching <br />rates will be mutually identified prior to implementation and should represent <br />grasses, shrubs and forties. <br />The north facing slope would have the aforementioned treatments, but the <br />seeding should be augmented with more shrubs and tree species. Vegetation <br />diversification needs to optimize on the micro c]imatic opportunities and the <br />• increased soil moisture of the north facing slope should be assessed for its <br />potential. <br />Tree planting should also be considered for along the southeast drainage <br />ditch. This sheltered location would also have increased soil moisture for <br />vegetation diversification, but species comparisons would not be variables for <br />formal investigation due to a lack of sufficient space for test plots. <br />The flat surface on the top of the refuse would accomodate three mulch <br />variations: Sewage sludge, 3 tons per acre renovated in the top 6" of soil, <br />and 6 tons per acre renovated. Each one of the applications would have three <br />repetitions so that the approximate surface pattern would look: <br />1 2 3 <br />3 1 2 <br />2 3 1 <br />Specific transect and monitoring points would be located within each treatment <br />area and the triple repetition would be used for statistical validation. <br />The same seed formula as placed on the west slope would be "drilled" on the <br />top and mulched according to location. The straw would be "crimped" with a <br />serrated disc to a depth not to exceed 2.5 inches. The "straw" should be a <br />• <br />
