6Denver Wetland Mitigation Banks Update (8/9/18)
The U.S. Army Corps of Engineers (Corps) has confirmed the Middle South Platte River Wetland Mitigation Bank has sold out of credits, which means there are currently no Corps approved mitigation banks with available credits in the Denver Front Range area.  Additional mitigation banks are currently being proposed and undergoing agency review.  Until these banks are open, any projects requiring wetland mitigation will need to provide permittee-responsible (on-site or off-site) wetland mitigation to compensate for wetland impacts.  

If any projects are anticipated to impact jurisdictional wetlands, project teams should evaluate ways to avoid and minimize impacts to the greatest extent possible.  If mitigation is necessary, ERO can assist project teams with developing mitigation plans, including evaluating possible on-site and off-site mitigation sites, designing wetland mitigation areas, and creating seed mixes and planting plans.

Please feel free to contact Moneka Worah, Clint Henke, or your ERO project manager if you have any questions. 

8Navigating the Changing NEPA Landscape

Recent administrative directives concerning National Environmental Policy Act (NEPA) compliance will change the way federal agencies process environmental reviews. These include:

Executive Order (EO) 13807, "Establishing Discipline and Accountability in the Environmental Review and Permitting Process for Infrastructure Projects." States that "processing of environmental reviews and authorization decisions for new major infrastructure projects should be reduced to not more than an average of approximately 2 years."

Secretarial Order 3355, "Streamlining National Environmental Policy Act Reviews and Implementation of Executive Order 13807." Sets page limits for environmental impact statements (EIS) (300 pages for complex projects, excluding appendices) and sets more ambitious goals for timelines (1 year for a Final EIS), for which a Department of the Interior bureau is the lead agency.

Council on Environmental Quality’s (CEQ) initial list of actions it will take to comply with EO 13807. Includes new guidance on establishing, applying, and revising Categorical Exclusions under NEPA; improving the process for preparing efficient and timely environmental reviews under NEPA; improving appropriate use of mitigation, monitoring, and mitigated Findings of No Significant Impact; and issuing additional guidance to agency heads as the CEQ may deem necessary to simplify and accelerate the NEPA process for infrastructure projects.

Although currently focused on infrastructure projects, similar directives may be issued that apply to other project types. The aim of these directives is to streamline the NEPA process to obtain more efficient and effective federal infrastructure decisions, avoiding time-consuming and costly delays. Agencies are currently developing direction and guidance to meet these new directives.

To comply with EO 13807 and NEPA and other environmental regulations, we anticipate that federal agencies may rely on "pre-NEPA" processes – prior to initiating the formal NEPA process – to:

• Develop preliminary purpose and need statements and project goals
• Conduct more detailed project alternatives analyses
• Identify environmental constraints
• Conduct data collection and preliminary analyses

Implementation of these new directives will take some time, and what they mean for projects will continue to evolve.

How do these processes differ from NEPA compliance in the past 10 years? What can be done now to ensure an expedited environmental review process for my time-sensitive project? ERO can guide you through these questions and assist in developing and executing a work plan. Please contact your ERO Project Manager for additional information about streamlining NEPA and pre-NEPA services. Click here for our staff contacts, or email ERO.

10Trust for Public Land - Willow Bay Property added to the South Platte River Trail

July 17, 2017: Adams County Parks & Open Space and the Trust for Public Land (TPL) announced the acquisition of 174-acre Willow Bay property located adjacent to the South Platte River, making a 110-acre lake a new public open space amenity in Adams County.

30New Corps/SHPO Guidelines for 404 Permits and Section 106 Compliance
March 8, 2017

As many of you have become increasingly aware, the U.S. Army Corps of Engineers, Denver Regulatory Office (Corps) began requesting exploratory shovel testing in permit areas in addition to the standard pedestrian survey. The purpose of exploratory testing, or shovel testing, is to identify potential buried archaeological sites that cannot be identified on the surface. Unfortunately for some of our clients, these requests began after the standard pedestrian survey had occurred and the report was submitted for consultation. 

Why the change?
This change in survey methods has come about as a result of the Corps consulting with the State Historic Preservation Office (SHPO) during Section 106 compliance reviews. The SHPO now recognizes the potential for buried archaeological sites within permit areas that contain "sediments conducive to containing buried cultural resources." These sediments are often referred to as "Piney Creek" alluvium from studies conducted in the 1950s.

ERO understands this methodological shift originated for two reasons: first, recent turnover in personnel at the Office of Archaeology and Historic Preservation has resulted in the use of methods typically applied to the eastern U.S. where exploratory testing is commonplace. The second reason is regulatory. The Corps interprets Section 106 through Appendix C of 36 CFR 325 instead of through the National Historic Preservation Act's implementing regulations (36 CFR Part 800). Despite interagency litigation at the Washington D.C. level between the Corps and the Advisory Council on Historic Preservation (SHPO's federal regulatory arm), there has been no resolution on this issue. 

To avoid conflict, the Corps has increasingly agreed with SHPO requests to 1) consider an area of potential effect (APE) that includes uplands and not just within areas of Corps' jurisdiction (waters of the U.S.), and 2) conduct exploratory testing (i.e., the vertical APE) on landforms conducive to containing buried cultural deposits. While the SHPO has not formalized this new guidance in their Survey Handbook, ERO understands that the handbook is actively being revised to include exploratory testing as part of the "reasonable and good faith effort" to identify historic properties within an APE.
What does this mean for your 404 permit projects and what steps is ERO taking?
404 permit applicants can expect requests from the Corps to conduct exploratory testing following their consultation with the SHPO. If the additional work is not implemented as part of the pedestrian survey and reported concurrently, this request typically results in an additional round of consultation between the two agencies and potentially delays your project another 60 days. To stay ahead of the issue, ERO has been addressing the issue by:

1. Conducting a preliminary geomorphic desktop analysis of a project area using data and our experience and expertise to eliminate landforms that would not require exploratory testing. Clients can use this information during project planning to decrease costs associated with exploratory testing and reduce the potential for constraints if exploratory testing results in positive results for subsurface archaeological deposits. 

2. Coordinating early with the Corps and our clients to identify areas that will be permitted and conducting exploratory testing prior to Section 404 permitting submittals. A proactive approach allows ERO and our clients to identify and plan around constraints, reducing the time it takes for the Corps and SHPO to conclude consultation. 

What happens if an archaeological site is found during exploratory testing?
It is not uncommon for buried archaeological sites to be found during exploratory testing. Buried archaeological sites are typically found to be significant because of their potential to provide information important to interpreting prehistory and, therefore, require avoidance. If avoidance is not feasible, archaeological treatment may need to occur, which can significantly delay the start of a project. The earlier that buried archaeological sites are identified, the easier it is to avoid or minimize effects through project redesign and to resolve adverse effects if the site cannot be avoided.

Requests for exploratory testing certainly add another layer of complexity to 404 permits and Section 106 compliance. Being proactive can greatly reduce the potential for project delays due to additional rounds of consultation. Early identification of potentially significant buried archaeological sites allows for early project redesign before permit submittal to the Corps. 

ERO looks forward to helping you navigate these new procedures. Please feel free to contact your ERO project manager or ERO's cultural resource manager, Sean Larmore, with any questions via email or 970-422-2136. 

55Corps and EPA Final Rule Defining Waters of the U.S. Under the Clean Water Act
June 29, 2015
Today the U.S. Army Corps of Engineers and Environmental Protection Agency jointly published in the Federal Register a final rule defining the phrase “waters of the United States” under the Clean Water Act (CWA). The rule will go into effect in 60 days.

The final rule will affect the scope of the EPA’s and Corps’ jurisdiction under Section 404 of the CWA. It is particularly likely to affect the jurisdictional status of ephemeral and intermittent tributaries that will become jurisdictional by rule and ditches.

What Will Likely Happen?

At this time, it is not known how the agencies will interpret the final rule; however, as written, it is likely to expand the agencies’ geographic scope of jurisdiction under Section 404 of the CWA when compared with how the agencies currently determine the geographic scope of their Section 404 jurisdiction. The Corps has indicated they will not issue any approved jurisdictional determinations until the rule goes into effect at the end of August. Those holding previously approved jurisdictional determinations that reached a conclusion that a water or wetland was nonjurisdictional based on isolation or lack of a significant nexus should carefully evaluate the likelihood of being able to receive an extension of the approved jurisdictional determination under the new rule. Project proponents should consider implementing their projects prior to the termination of their approved jurisdictional determination if the wetland or water previously determined nonjurisdictional is likely to be determined jurisdictional under the new rule.

59Clean Water Act – Approved Jurisdictional Determinations and Nationwide Permit Renewal - Update
On May 31, 2016, the U.S. Supreme Court unanimously concluded that an approved jurisdictional determination (JD) issued by the U.S. Army Corps of Engineers (Corps) under the Clean Water Act is a final agency action that is judicially reviewable under the Administrative Procedure Act.  Simply put, approved JDs can now be appealed in court.  The extent to which this may open the door for third parties opposing a project to file a lawsuit regarding a Corps-approved JD is yet to be clarified.  We anticipate that with the potential for challenge, the Corps will likely require more information from applicants requesting approved JDs to defend their decision in court.  Consequently, approved JDs will likely take more time to be issued by the Corps, will cost more because of the additional information, yet will have less certainty because of the potential for appeal.  

The Corps will likely issue guidance on this decision and ERO will inform our Clients on any new guidance when it has been issued.  

The Clean Water Act Section 404 Nationwide Permits (NWPs) expire on March 18, 2017 and the Corps released the draft proposal to reissue and modify the NWPs.  ERO will be reviewing and providing comments on the proposal and will notify our Clients if any modifications are likely to affect them.

80Peaks to Plains Trail - GOCO Grant

October 12, 2016

ERO is proud to be part of the team that has been studying trail alignments for the Clear Creek Canyon mouth segment of the Peaks to Plains (P2P) Trail. ERO scientists completed natural and cultural resource assessments for the master plan, as well as Ute ladies’-tresses orchid and Preble’s Meadow Jumping Mouse surveys. In addition, ERO also assisted Jefferson County with completing an environmental checklist as part of the successful GOCO grant application.

The vision for the Peaks to Plains Trail is a 65-mile off-highway opportunity to travel from the Continental Divide at the Eisenhower Tunnel to the confluence of the South Platte River in Adams County.

90Corps of Engineers/Section 404/Cultural Resources Compliance Update

ERO works closely with the U.S. Army Corps of Engineers’ (Corps) Denver Regulatory Office of the Omaha District, and has begun to see a shift in how the Corps complies with Section 106 of the National Historic Preservation Act and determines the extent of areas requiring evaluation for potential effects on historic properties.  

More Clean Water Act Section 404 permit reviews are resulting in requirements for cultural resource surveys, not only in areas of disturbance directly associated with impacts on waters of the U.S., but also in areas of upland disturbance they consider connected to the overall project purpose.

For example, if drainageway improvements in a new residential development are required as part of the local development approval process, the Corps may consider the drainageway improvements a necessary part of the overall project purpose of constructing a residential development. In that case, the Corps requires that the entire development parcel be evaluated for historic properties, rather than just the area of disturbance associated with the drainageway improvements.

This evolving approach to determining the “permit area” can result in unexpected project costs and delays, particularly if historic properties are present and would be adversely affected by a project.

To address this uncertainty, ERO is assisting our clients by:

  • Performing cultural surveys as part of property acquisition due diligence
  • Participating in project planning and design teams to evaluate alternatives for compliance strategies
  • Coordinating as early as possible with the Corps to determine an appropriate “permit area”
  • Developing impact avoidance and minimization approaches when historic properties are present
  • Frequently communicating with the Corps to track how they are addressing this issue

If you have a project that may be facing this issue or would like additional information, please contact Sean Larmore or Jenelle Kreutzer.

100ASTM Updates Phase I ESA Standard

November 6, 2013 - ASTM International has just issued the updated Phase I Environmental Site Assessment (ESA) E1527-13 standard for due diligence prior to real property transactions.

In ERO's opinion, the revisions to the E1527 Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process are not a radical departure from the previous process and incorporate improvements reflective of the marketplace.

Notable revisions include:

- Updated Recognized Environmental Condition definition;

- New, updated, and clarified terminology for sites with historical contamination;

- Greater emphasis of vapor migration within the Phase I ESA investigation; and

- Agency file review requirements within the Phase I ESA process.

Although the EPA has yet to issue a final ruling that the new standard is compliant with the "All Appropriate Inquiries" regulation, we have been told that this ruling should be issued by the end of the year. ERO is excited about this transition to a new standard and we would be happy to discuss the changes.

Please feel free to contact Jack Denman, ERO Environmental Scientist/Principal, if you have any questions.

2502015 Grand Award for Engineering Excellence

ERO is extremely proud to be part of the team that received CASFM's 2015 Grand Award for Engineering Excellence for the Cherry Creek Valley Ecological Park Project. 

Team members include:

ECI Site Construction
Naranjo Civil Constructors
Muller Engineering
The Restoration Group
Arapahoe County Open Spaces
Southeast Metro Stormwater Authority
Urban Drainage and Flood Control District
Cherry Creek Basin Water Quality Authority
Cherry Creek Stewardship Partners
Parker Jordan Metropolitan District

"The 2015 CASFM Engineering Excellence Award winning project was the Cherry Creek Valley Ecological Park project! The project stakeholders included: Arapahoe County Open Space, Southeast Metro Stormwater Authority, Urban Drainage and Flood Control District, Cherry Creek Basin Water Quality Authority, Muller Engineering Company, ERO Resources, and Valerian.

Eco Park is a 75 acre open space located along a 5,100- foot reach of Cherry Creek upstream of Cherry Creek Reservoir in Centennial, Colorado. Urbanization and the resulting increase in storm runoff took a toll on the area’s natural systems, leading to stream erosion, loss of vegetation, degraded water quality, and infrastructure damage. 

To correct these issues, the project partners embarked on a multi-phase project to address these issues and to turn the park back into its natural setting that illustrates the different ecosystems working together to create habitat for animals as well as a system of pathways and opportunities for human recreation. The project was completed in the spring of 2014, and the overall cost was $5,025,000. In the end, this project is evidence that preserving drainageways within urban settings and complementing them with educational and recreational facilities provides value to both the public and surrounding environment.” - CASFM web site.

Several ERO staff volunteered their time to assist the Colorado Renewables and Conservation Collaborative (CRCC) with development of Best Management Practices (BMPs) for wind energy development in Colorado. ERO staff provided professional expertise to the CRCC through participating in meetings, providing resource information, and consulting on specific issues, such as wetland protection.
