Lyman Richey Corporation proposes a new sand and gravel mining operation on the RNM property located west of Valley, Nebraska in northeast Douglas County. The proposed project would occur in four phases over 21 years and result in the discharge of fill material into waters of the United States, including wetlands. Impacts are divided into each phase of the project and are listed below.
Phase 1—Years one to five—A total of 6.27 acres of PEMA/C riverine floodplain wetlands will be impacted by Phase 1. Phase 2—Years six to ten—A total of 5.44 acres of PEMA/C riverine floodplain wetlands will be impacted by Phase 2. Phase 3—Years eleven to fifteen—A total of 4.84 acres of PEMA/C riverine floodplain wetland will be impacted by Phase 3. Phase 4—Years sixteen to twenty-one—A total of 7.39 acres of PEMA/C riverine floodplain wetlands and 3,810 linear feet of an unnamed tributary to Western Sarpy Ditch will be impacted by Phase 4. If a permit decision is made to authorize, the permit would be evaluated every 5 years in order to address any changes to the project, which may include but is not limited to, impacts, mitigation, endangered species, or jurisdiction.
