more cost effective without a large change to the processes,” says Smith. The new process also cuts down signifi-cantly on the costs for fuel and water for the water truck. Landﬁ ll Covers Solid waste landfills must not only control odor, but also maintain dust control to be good neighbors. For many landfills around the country, the choice is Soiltac, manufactured by Soilworks of Gilbert, AZ. Soiltac can be applied to the earthen caps that cover landfill sections. The product consists of long copolymer molecules with multiple links and cross-links. The concentrate is mixed with water, with the ratio depending on the site and use. The mixture is sprayed on the soil by water truck or sprayer applicator. The white fluid begins to disappear, but the soil surface will appear darker. The mixture penetrates into the soil, forming the flexible solid mass that will capture and encase fines so they cannot escape as dust. After it dries, Soiltac is transparent. The product is non-corrosive to equipment and will not rinse away in rain. It can last from weeks to several years, depending on the concentration of the application. Reclamation In The Oil Fields Chief Oil and Gas wanted to reclaim the Dacheux Water Transfer Pad at a well in Cherry Township-Sullivan County, PA. The company needed a time and cost-effective way to revege-tate the bare pad and the slopes around it. Erosion control blankets were considered, but the final choice was EarthGuard Fiber Matrix, a product from LSC Environmental Products of Bakersfield, CA. EarthGuard Fiber Matrix combines 100% wood fiber with a soil stabilizer. The stabilizer is designed to directly impact soil to corral any fines, and to keep the soil structure intact, protect-ing it from wind and rain. It consists of high-molecular-weight polymer emulsions. The product can be used for winterization, without seed, to protect bare soil, slopes, and stockpiles during the rainy season. It can also have added seed for quick growth when the condi-tions are warm enough. For seed estab-lishment, amendments can be included to give the seeds a good start. Penn Line Service performed the application at a rate of 10 gallons and 2,500 pounds per acre. Other products often require heavier loading of fiber. After five weeks, significant growth had occurred, making the pad and slopes stable for the winter ahead. Keith Kimball, construction inspec-tor for Chief Oil and Gas, says, “I have been very happy with EarthGuard’s overall performance.
