CEMENT program calls for the use of oaks, California Bay trees, manzanita, and other shrubs, trees, and grasses native to the surrounding area. While beautification work is undertaken by -companies in the U.S., employees at all levels in the cement plants in Russia were expected to contribute at least 20 hours annually for planting. The Angarsk cement plant received the Government's "Protection of Russia's Nature" medal for landscaping the grounds with 40,000 trees, 50,000 shrubs, and flowerbeds. Waste heat from the kilns was utilized in greenhouses to grow vegetables. Cimeats La-farge's new plant at Port is Nouvelle received an award worth Fl0,000 from the French Minister of the Environment for protection of the landscape and dust and noise control. T-welve percent of the capital cost of this plant was spent on pollution control. -After conducting waste reclamation tests using an idle kiln at Alpha Portland Industries' old plant in LaSalle, IlL, All American Environmental Control Corp. (AENCO) of Wilmington, Del., purchased the idle Lehigh Portland Cement Co. Fordwick plant near -Craigsville, Va. AENCO proposed to solve the Washington, D.C., -metropolitan area solid waste disposal problem by processing at least 500 tons of refuse a day. In addition to reclaiming metallic wastes, AENCO planned to start a mushroom growing center using constituents of the processed waste as compost. Despite public clamor by ecologists and environmentalists a-bout solid waste disposal, no one in the Nation's Capital was willing to supply waste to operate the plant. Solid wastes from the metropolitan areas of Baltimore, Md., and Richmond, Va., could not -be obtained either. A court action that could adversely affect cement sales in the construction sector occurred on September 21 when the California Supreme Court, in a 6 to 1 decision, decreed that State and local governmental agencies must file written environmental impact statements on applications for private as well as public construction projects that may affect the environment under the State Environmental Quality Act. The decision will allow citizens to sue to halt any significant private construction project that doesn't have an environmental impact study. Acting on the advice of city attorneys, many communities curtailed or corn- 251 pletèly stopped the issuance of building permits, even for repairs to existing structures, pending interpretation of the C-ourt's ruling or action by the State Legislature. Other States were expected to follow California's lead. EPA testimony at the Price Commission Hearing in Houston, Tex., estimated that electrostatic precipitators cost a-bout $1 million ea-ch and fabric bag dust collectors cost approximately $600,000 each.
