Wetland Delineations Project scheduling and timing –May be seasonal restrictions (winter, growing season Locating and siting wetlands –Blue and white area on USGS maps could be waters of the U.S. Delineate the wetland –Jurisdictional determination –Map and document
Nationwide Permits For common activities with minimal wetland/waters of the U.S. impacts Typical NWPs applicable to O&G activity –NWP 12: Utility Line Activities –NWP 14: Linear Transportation Projects –NWP 27: Stream and Wetland Restoration Activities
Individual Permits For projects > 0.5 acre impacts to wetlands or other waters of the U.S. or > 300 linear feet of streambed fill Public review of permit application –15 to 30 day public comment period Mitigation plan and implementation required Generally take 4 to 6 months for approval
Nationwide Permits Submit Preconstruction Notification (PCN) –Permittee contact info –Project description, location, purpose –Quantify unavoidable wetland impacts –Other environmental impacts –Maps, photos Corps has 45 days to respond to PCN “The prospective permittee shall not begin the activity…Unless 45 days have passed from the District Engineer’s receipt of the complete notification.” NWPs may take 90 days to process if mitigation required
Mitigation “No net loss” of wetlands –Typically 1:1 mitigation ratio in Colorado –Varies depending on habitat value, quality –“After-the-fact” typically higher ratio Restoration Creation Enhancement Mitigation bank guidance
Mitigation Aspects and Costs Planning Construction Annual Monitoring Maintenance Army Corps must sign off on completed mitigation (Typically 3 to 5 years for success)
Wetland Mitigation Site Adams County, Colorado 2003 - Baseline Photo2005 – Same Location After Wetland Creation We obtained Corps of Engineers sign-off of the mitigation at this site only 2 years after implementation.
