ACTON – Federal officials have asked for public comment on a mining company’s bid for a 20-year extension of its permit to draw clay from an Acton quarry. Because the North Star Minerals Inc. mine lies within the Angeles National Forest, the U.S. Forest Service has the final say on the company’s permit. The agency is collecting public opinions through May23. Under its plan, North Star would continue crushing and screening ore and hauling it onto Aliso Canyon Road. The proposal provides for maintenance of an auxiliary road, dust control on the road and at the quarries, restrictions on hours of operation depending on conditions, and reclamation of areas as they are mined. North Star’s original permits granted in 1991 will expire in December. The company wants to expand its work to mine 24acres over 20 years, 5acres at a time. So far, no opposition has surfaced, district ranger John Capell said. The quarries yield materials used in industry. Comments can be sent to Jonathan Schwartz, Santa Clara-Mojave Rivers Ranger District, 30800 Bouquet Canyon Road, Saugus, 91390. The proposal can be viewed at http//www.fs.fed.us/r5/angeles.
