NWO-2015-00766-MTH - 12/26/2017: Regal Talc Mine expansion consists of modifying and or relocating approximately 1330 linear feet of Hoffman Creek impacting 0.72 acre of wetland. The impacted Hoffman Spring Creek channel reach of approximately 730 linear feet is located on the downstream half of the drainage immediately above its confluence with Hoffman Creek. The 730 linear feet of impacted Hoffman Spring Creek channel includes about 530 linear feet that will be removed by the expanded mine pit (including adjacent safety bench, berm, and access road), and about 200 linear feet that will be affected by construction of the uppermost part of the realigned channel, including a catchment basin and cutoff wall. The engineered realigned channel will extend from the new catchment basin constructed in the existing channel, and then to Hoffman Creek through uplands, with an elevation change of approximately 47 feet. At the confluence, the realigned channel will merge with the natural Hoffman Creek channel, and will include a groundwater cutoff wall constructed beneath and perpendicular to Hoffman Creek immediately upstream of the confluence. All of these areas are characterized by intermittent stream flow. The impacted Hoffman Creek channel of approximately 600 linear feet will be located both upstream and downstream of its confluence with Hoffman Spring Creek. The modification will consist of channel consolidation with natural sealing minerals (bentonite) mixed to a depth of approximately 6 inches, and native soft armoring utilizing existing channel debris/stone and local riparian cuttings.

NWO-2012-01895-WEH_Phase2 - 12/22/2017: The Nebraska Department of Transportation (NDOT) is proposing to expand approximately 9.6 miles of United States Highway 30 (US-30) from a two-lane highway to a four-lane expressway. The current proposed project, Rogers to North Bend, is the second phase of the entire Schuyler to Fremont US-30 project, which is proposed to be constructed in three phases. The project would begin along the existing US-30 alignment approximately 0.8 mile east of the Colfax/Dodge County line. The project would diverge from the existing US-30 alignment between Dodge County Roads 3 and 4 and would curve to the northeast to provide a wider northern bypass around North Bend. It would then curve southeast between Dodge County Roads 9 and 10. From this point, the alignment would be located approximately 200 feet south of Dodge County Road S and would end near County Road 11.

NWO-2017-01439-RWY - 12/21/2017: Seneca Industries, Inc., has requested authorization to construct Badger Creek Reservoir north of Cora Wyoming. The project purpose is supplemental water supply for late season irrigation of lands supplied by the existing Simmons Ditch (P2670D), which has an original supply from Big Twin Creek. The applicant has identified an average annual need of up to 281 acre-feet. Water would be diverted from the reservoir to the ditch through a pipeline and used to irrigate 276 acres of land currently producing hay and another 62 acres of land would be brought into production.

NWO-2016-2413-PIE - 11/30/2017: In response to a need to construct BMP detention ponds within the northeast side of Sioux Falls, South Dakota in order to help regulate water quantity and quality within the area, the City of Sioux Falls requests authorization to construct the Regional BMP 25-1 West Pond just north of Madison Street and to the east and west of the newly-constructed Veteran’s Parkway (Highway 100). The project will involve excavating two storm water detention ponds on each side of Veteran’s Parkway, constructing/grading side slopes to a 4:1 slope, constructing a forebay on the west side of Veteran’s Parkway, constructing a concrete weir to regulate the 100-year flow, and constructing a maintenance road along the boundary of the BMP ponds. The project will impact 0.66 acres of wetlands. The purpose of the proposed project is to keep peak flow rates comparable to existing condition peak flow rates and provide storm water treatment as development continues within the area.
