1975 Voto de la Tarjeta de Evaluaciones
The Surface Mine Control and Reclamation Act of 1975 (H.R. 25). The vote is on the Spellman amendment to prevent strip mining on slopes greater than 20 degrees. In a 1973 Senate study, a survey of landslides in Kentucky showed that 86% of the slides from strip mining were on slopes of 20 degrees or more, and that 3 to 5 acres of land are disturbed for every acre stripped on steep slopes. Environmentalists have attempted to include a 20 degree ban since the first strip mining bill was considered in 1972. Rejected 136-262. March 17, 1975. ÒYESÓ is the correct vote.
