Enhancing Nationwide Wetland Permitting: Integrating the Stream Duration Assessment Model (SDAM) with State-Specific Approaches Across the U.S

The U.S. Army Corps of Engineers (USACE) has developed the Stream Duration Assessment Model (SDAM), a groundbreaking tool that significantly enhances the regulatory oversight and protection of the nation’s water resources. This model plays a critical role in managing and safeguarding streams and wetlands, crucial for maintaining biodiversity, water quality, and flood mitigation. The SDAM is designed to classify streams based on their flow characteristics—perennial, intermittent, or ephemeral—crucial for determining the jurisdictional status of water bodies under the Clean Water Act (CWA). This article explores the integration of state-established models with the SDAM for regulatory purposes and highlights its nationwide applicability for wetland permits.

The SDAM employs a science-based approach, integrating hydrological data, GIS analyses, and field observations to assess stream flow characteristics accurately. This standardized method is vital for delineating the scope of regulatory oversight, ensuring environmental impacts are thoroughly evaluated and mitigated, particularly in the context of Section 404 of the CWA, which governs the discharge of dredged or fill material into waters of the United States.

State-established models of stream flow complement the SDAM by providing detailed insights into the flow regimes of streams within specific geographic areas. These models, developed based on localized data, enhance the precision of the SDAM by incorporating nuanced understandings of stream behavior, reflecting the unique ecological conditions of different regions. Integrating these models involves aligning methodological approaches, standardizing stream type definitions, and harmonizing data analysis techniques to ensure consistency across jurisdictions.

The combined use of the SDAM and state models offers a more nuanced assessment of streams for regulatory purposes. It facilitates more informed decisions regarding wetland permits by identifying streams with significant ecological functions or those critical to maintaining watershed health. This approach supports a more adaptive and responsive regulatory framework, allowing for updates with new data as environmental conditions change, ensuring the relevance and effectiveness of stream assessments.

Nationwide, the applicability of the SDAM, enhanced by state-specific models, encourages collaboration among federal, state, and local agencies. This collaborative approach improves the regulatory process’s efficiency and fosters a shared commitment to protecting water resources. It exemplifies the balance between economic development and environmental stewardship, promoting the sustainable management of aquatic ecosystems.

Furthermore, the integration of state models with the SDAM highlights the USACE’s commitment to using science and technology to improve environmental regulation. It reflects a shift towards data-driven decision-making, setting a precedent for future innovations in water resource management. As the model is refined and updated, its utility for regulatory purposes will continue to improve, ensuring that development and infrastructure projects proceed in an environmentally responsible manner.

The integration of the Stream Duration Assessment Model (SDAM) with state-specific methods, such as the North Carolina (NC) method for assessing stream flows, exemplifies a tailored approach to environmental regulation and water resource management. North Carolina has developed its own methodologies for classifying streams and assessing their ecological significance, which can complement the broader framework of the SDAM.

Example: North Carolina’s Stream Identification Method

North Carolina’s method for stream identification and classification is designed to meet the unique ecological and hydrological conditions of the state, which range from the Appalachian Mountains in the west to the coastal plains in the east. This method involves detailed field assessments, including the examination of physical, chemical, and biological indicators to determine stream types and their jurisdictional status under state and federal regulations.

Key aspects of the NC method include:

  1. Physical Indicators: These include the presence of a well-defined channel, bed and banks, and evidence of flow (e.g., water marks, sediment sorting) to distinguish between perennial, intermittent, and ephemeral streams.
  2. Biological Indicators: The presence of aquatic life, such as fish and macroinvertebrates, which are indicative of perennial or intermittent streams capable of supporting diverse biological communities.
  3. Hydrological Data: Use of historical precipitation, stream gauge data, and other hydrological models to predict flow durations and patterns throughout the state’s diverse landscapes.

Integrating the NC method with the SDAM allows for a comprehensive assessment that leverages local expertise and data while aligning with national standards for water resource management. This integration enhances the precision of stream classifications and the effectiveness of regulatory processes, including permitting for activities that impact water resources.

For example, when a developer proposes a project in North Carolina that may affect waterways, the combined use of the NC method and the SDAM ensures a thorough evaluation of potential impacts on stream flow and aquatic habitats. This dual approach facilitates informed decision-making regarding permit issuance, mitigation measures, and conservation efforts, balancing development needs with environmental protection.

Nationwide Implications

The example of North Carolina illustrates how state-specific methods can enhance the effectiveness of the SDAM in managing water resources across the U.S. By integrating localized approaches with the broader framework of the SDAM, states can ensure that regulatory processes are adapted to their unique environmental conditions, promoting sustainable water resource management and protection at both the state and national levels. This collaborative approach underscores the importance of tailored strategies in addressing the complex challenges of environmental stewardship and water resource regulation.

Wetlands at the Water’s Edge

Navigating the Confluence of WOTUS, SDAM, and OHWM in Ecosystem Assessment

The integration of the Waters of the United States (WOTUS), the Stream Duration Assessment Model (SDAM), and the Ordinary High Water Mark (OHWM) in wetland assessment provides a holistic approach to identifying and protecting these ecologically significant areas. However, this integration is not without its challenges, which stem from the complexity of wetland ecosystems, the nuances of environmental regulation, and the need for precise scientific data. Expanding on these challenges and opportunities reveals the intricacies involved in effective wetland management.

Data Precision and Availability

One of the foremost challenges in integrating WOTUS, SDAM, and OHWM is the need for high-quality, precise data. Wetland assessment requires detailed information on hydrology, soil types, vegetation, and other ecological indicators. The accuracy of this data directly impacts the determination of WOTUS boundaries, the application of SDAM, and the identification of the OHWM. However, obtaining such data can be resource-intensive, requiring extensive field surveys, remote sensing technology, and hydrological modeling. Moreover, the dynamic nature of wetlands, which may change seasonally or due to climate impacts, adds to the complexity of maintaining up-to-date and relevant data.

Interagency Coordination

Effective integration of these assessment tools also depends on robust interagency coordination. The regulatory landscape of wetland protection in the United States involves multiple federal agencies, including the Environmental Protection Agency (EPA), the U.S. Army Corps of Engineers, the U.S. Fish and Wildlife Service, and state and local entities. Each agency may have different mandates, priorities, and methodologies, which can lead to challenges in achieving a unified approach to wetland assessment and protection. Streamlining communication, data sharing, and regulatory processes among these entities is crucial for the effective implementation of WOTUS, SDAM, and OHWM standards.

Dynamic Nature of Wetland Ecosystems

Wetlands are dynamic systems that respond to a variety of environmental factors, including precipitation patterns, river flow regimes, and human activities. The transient nature of these ecosystems poses a significant challenge to the static frameworks used for their assessment and regulation. For instance, the OHWM might shift due to natural sedimentation processes or human-induced changes in water flow, requiring constant monitoring and adjustment of regulatory boundaries. Similarly, the flow characteristics used in SDAM assessments may vary, affecting the classification of water bodies connected to wetlands. Adapting regulatory approaches to account for these dynamic changes is essential for the long-term protection and management of wetland resources.

Legal and Policy Frameworks

The legal and policy frameworks governing wetland protection, particularly the definition and application of WOTUS, have been subject to significant legal challenges and policy shifts over the years. These changes can lead to uncertainty and inconsistency in wetland assessment and protection efforts. For practitioners and stakeholders, staying informed about current regulations and understanding how they apply to different wetland types and situations is a continual challenge. Ensuring that legal frameworks are both scientifically grounded and flexible enough to adapt to new environmental insights is crucial for effective wetland management.

Conclusion

Integrating WOTUS, SDAM, and OHWM in wetland assessment requires navigating complex environmental, regulatory, and technical landscapes. Addressing the challenges of data precision, interagency coordination, the dynamic nature of wetlands, and evolving legal frameworks is essential for creating a coherent and effective approach to wetland protection. Embracing adaptive management strategies, fostering collaboration among stakeholders, and investing in research and monitoring are key steps toward ensuring that wetlands continue to provide their invaluable ecological services for generations to come.

Scout Motors is Filling In a Lot of Wetlands

COLUMBIA, S.C. — Environmental advocates are closely monitoring the developments at the site of the massive electric vehicle plant slated for Blythewood in Richland County, with growing concerns about its impact on the delicate wetlands in the area.

Construction crews are back to work after receiving a permit from the U.S. Army Corps of Engineers, allowing them to resume work that had initially been halted due to worries about wetlands damage.

This project has garnered significant attention, particularly after a report by WIS 10 news suggested that the Scout site could potentially impact a staggering 70,000 acres of wetlands, nearly 40,000 acres of ponds, and approximately 35,000 linear feet of tributaries. However, it’s important to note that this report is highly inaccurate and continues to be the top result in Google news searches related to the project.

While the correct figures are somewhat lower, they are still concerning. The USACOE’s permit will authorize the filling or disturbance of 74 acres of wetlands, 38 acres of ponds, and 7 miles of creek.

The new Scout Plant is situated off Interstate 77 in the northern part of Richland County, but questions and apprehensions loom large regarding its potential environmental impact, and the community is eagerly awaiting answers.

Blythewood Mayor Sloan Griffin shared his thoughts, saying, “It’s scary. Change is always accompanied by uncertainty. There are two sides to every coin – heads and tails. Some are excited, looking forward to the promise of 4,000 jobs and increased business opportunities in Blythewood, thanks to Scout.”

Construction will soon resume on the vast 1,600-acre site in Blythewood, where the Scout Motors manufacturing plant is set to be located.

Last September, Scout had to pause its work following concerns raised by the Environmental Protection Agency (EPA), which had identified evidence of wetlands damage even before the permit was issued.

Additionally, there’s a noteworthy finding indicating that one of the archeological sites, known as 38RD1468, is recommended for inclusion in the National Register of Historic Places (NRHP) under Criterion D. It holds potential for yielding significant insights into the area’s prehistory. However, it’s important to mention that there was not enough data collected during the Phase II investigations to determine its eligibility under other criteria (Criteria A, B, and C).

The Scout Motors project is undeniably intriguing. They are embarking on the production of electric trucks, a technology yet untested in the transportation of goods. This raises questions about the necessity of destroying 75 acres of wetlands for an unproven technology that may or may not compete effectively with traditional trucking methods. While the transition away from fossil fuels is commendable, it’s crucial to ponder whether it should come at the significant cost of our natural environment. Surely, alternative locations with less environmental impact could have been considered for this venture.

EPA and the Department of the Army issue Amended Final Rule Defining WOTUS

By Rick Savage – Carolina Wetlands Association

On August 29, 2023, the U.S. Environmental Protection Agency (EPA) and the Department of the Army announced a final rule that amends the January 2023 definition of “waters of the United States” (WOTUS). The amendments conform the January 2023 definition to the U.S. Supreme Court’s decision in Sackett and will take effect immediately upon publishing in the Federal Register (likely to happen within two weeks). To read the pre-publication version of the revised final rule, go to Pre-publication Version of the Final Rule – Amendments to the Revised Definition of Waters of the United States (epa.gov). 

While exact details are yet to be digested, the gist of the ruling is becoming clear.  First, the significant nexus rule has been eliminated; so isolated wetlands are not jurisdictional wetlands, meaning they are not protected under the Clean Water Act.  Second, the new rule requires visual evidence of a continuous surface flow between a wetland and navigable water.  This part of the rule can get complicated as to what constitutes visual evidence of continuous surface flow.  I am sure that this will cause a lot of confusion and some developers will say there is no continuous surface flow and impact the wetland with a permit. 

Suffice it to say, this puts wetlands in North and South Carolina in jeopardy. The NC Department of Environmental Quality has estimated about 2.5 million acres of wetland have lost protection in North Carolina and I am sure a similar number in South Carolina.  The NC legislature could have continued to protect these wetlands; however, the recently passed Farm Bill eliminated state protection of isolated wetlands.   

We all need to brace ourselves for a lot of wetland loss and they are the very resource we need to protect our communities from flooding.  I think it is reasonable to expect more communities to get flooded, to have less clean water, and to have reduced climate resilience as well as miss the many other benefits that our wetlands provide. 

So go out an explore a wetland (before it gets developed?).

EPA Admit “Waters of the U.S.” Could Have Been Handled Better

Swamp Stomp

Volume 15, Issue 15

During the National Farmers Union convention in Wichita on March 16, 2015, U.S. Environmental Protection Agency Administrator Gina McCarthy expressed regret about how the EPA handled the controversial “Waters of the U.S.” rules.

Following U.S. Department of Agriculture Secretary Tom Vilsack, McCarthy spent the majority of her 30-minute speech claiming that she wished her agency had done a better job of explaining how EPA defined which bodies of water were regulated under the Clean Water Act.

McCarthy asserted, “I’m really concerned that we weren’t crystal clear out of the gate, not just about what we intended to do but about what we intended not to do, because it left all kinds of room for people to wonder not just what the words said but what we are trying to accomplish.”

Despite her regret over how the effects of rule were communicated, however, McCarthy is adamant that the EPA’s end goal will be met and the final rule be issued.  She said that the rule is currently on its way to the Office of Management and Budget and is expected to be issued this spring.

2105regs

After recent U.S. Supreme Court rulings, EPA is currently rewriting the rule, but McCarthy remains adamant that the need for the rule is clear. However, she did attempt to clarify what the rule would and would not intend to do. She provided the following assurances:

  • In response to numerous criticisms, McCarthy assured the public that EPA would not regulate puddles, land, or Fourth of July fireworks.
  • Addressing the worry that regulating “tributaries” could mean just about anything, McCarthy stated that EPA has established clearer definitions.
  • The rule does not include erosional features.
  • McCarthy claimed that roadside and irrigational ditches are not included, but ditches that are natural and constructed streams that can carry pollution downstream and act like tributaries are included.
  • Waters initially labeled as “other waters”—a term McCarthy conceded was too ill-defined—are in the process of being more narrowly stated by officials using their “best judgment.” However, the results of clarifying vague terms with even vaguer qualifications will most likely do little to quell concerns.

The main message of McCarthy’s speech was that farming and ranching should remain unaffected by the rule. “The exclusions and exemptions for agriculture . . . this rule we will not touch,” she said.

During Vilsack’s address, farm productivity was a major talking point. Farmers today are 12 times more productive then they were in 1950. Subsequently, Americans only spend 10 percent of their income on food, 15 to 20 percent less than many of the other countries in the world.

Vilsack also raised many concerns, including how to best introduce the next generation of farmer to the profession, labeling country origin of beef and pork in supermarkets, and how to best develop tools and support conservation and local agriculture, such as farmers markets.

“This isn’t just about farming. This isn’t just about agriculture. This is about rural life and maintaining the value system alive and well in the rural communities.”

While Vilsack is not forwardly addressing the “Waters of the U.S.” rule, he is assisting McCarthy paint an image of what the rule intends to do. The ambiguity of McCarthy’s speech did little to rid farmers and ranchers of their concerns, and her acknowledgment that the rule was not communicated as well as it could have been is somewhat diminished by “clarifying” points with terms that themselves are ambiguous.

 

Congress Pushes Back on New EPA WoUS Rules

Swamp Stomp

Volume 14, Issue 18

On May 1, 2014, 231 lawmakers led by U.S. Representatives Chris Collins (R-NY) and Kurt Schrader (D-Ore.), in the U.S. House of Representatives sent a letter to the EPA and U.S. Army Corp of Engineers to retract its proposed rule to expand federal control under the Clean Water Act. They have citied technical, legal and economic concerns regarding the new rules that have been published in the Federal Register.

Congress is most concerned with the legal position that the EPA and the Corps have taken by more or less basing the entire rule revision on Justice Kennedy’s lone opinion in the Rapanos case. The letter states, “Contrary to your agencies’ claims, this would directly contract prior U.S. Supreme Court decisions, which imposed limits on the extent of federal CWA authority,” the lawmakers stated in the letter. It went on to say that “Based on a legally and scientifically unsound view of the “significant nexus” concept espoused by Justice Kennedy, the rule would places features such as ditches, ephemeral drainages, ponds (natural or manmade), prairie potholes, seeps, flood plains, and other occasionally or seasonally wet areas under federal control.”

The letter also raised concerns with the economic analysis on which the proposed rule is based. In the agency’s analysis, it was determined that the proposed rule would result in a 2.7 percent increase in jurisdictional determinations and would impact an additional 1,332 acres nationwide under Section 404. They applied that 2.7 percent increase across other EPA permitting programs. The agencies determined that the draft proposed rule would result in costs between $133 million and $231 million annually. Based on this, the agencies have said the rule would not have a significant economic impact. The lawmakers disagree, saying errors in the analysis “call into question the veracity of any of the conclusions in the economic analysis.”

House Natural Resources Chairman Doc Hastings (R-Wash.) says the proposal is a massive power grab that must be stopped. “Under this plan, there’d be no body of water in America – including mud puddles and canals – that wouldn’t be at risk from job-destroying federal regulation,” he says.”

Read the full letter here.

To date the EPA has received more than 61,000 comments on the new rules. Your comments and suggestions are needed. So far a total of 789 comments have been published. Many support the new rules and a few do not. If you have any opinion on these new rules, please provide you comments by going to regulations.gov and searching for EPA-HQ-OW-2011-0880. From there you can see the entire docket and submit your comments.

Comments are due by July 21, 2014. If EPA and the Corps finalize these rules it is expected that they will be in force by the fall of this year.
