ABSTRACT
This webinar has been designed to help provide a basic overview for regulators that are new to oil and natural gas pipeline permitting and provide a review for others who already are engaged in this work. The webinar began with an overview of the expansion of oil and especially gas pipeline development in recent years and the associated growing need for review of pipeline permit applications by state and tribal aquatic resource regulators. The webinar covered pipeline basics – how pipeline projects are planned, the general steps in construction, and the potential to participate in a pre-application phase during which many key planning decisions are made. The webinar discussed the different processes involved in oil and gas permitting. Next, the webinar providef an overview of §401 Water Quality Certification and where this review process fits into overall planning and permitting. The webinar discussed examples of how states and tribes have dealt with conditioning §401 certifications and share lessons learned. The webinar concluded by describing new resources designed for those working on pipeline permitting that will soon be available on the Association of State Wetland Managers’ website.

ABSTRACT
Horizontal Directional Drilling (HDD) is often considered a best practice for pipeline construction. However, in practice, HDD is only appropriate in certain contexts. This webinar started with a geology primer identifying contexts where HDD both commonly works and does not work well and why. Next, the state and tribal regulators shared their perspectives on reviewing permits that include HDD and some of their lessons learned. They shared the kinds of information that it is beneficial for reviewers to request and common considerations when reviewing and conditioning permit applications that include proposed HDD. Alternatives to HDD and their strengths and weaknesses also was discussed. The webinar concluded with information about new resources for those working on pipeline permitting efforts that will soon be available on the Association of State Wetland Managers’ website.

PRESENTER
- Wing Goodale, Biodiversity Research Institute [PowerPoint Presentation]
ABSTRACT
Energy projects, particularly pipelines, affect a range of aquatic resources, including wetlands. Impacts to wetlands from pipeline activities range from both short- and long-term destruction and disruption of wetlands and other aquatic resources to water quality impacts, habitat loss, increasing invasive species and compromised quality of critical areas. The adverse effects of a pipeline on a single wetland are important, but of equal or greater concern is the effect of pipelines that cross multiple watersheds and multiple wetlands. A single pipeline can cross hundreds of wetlands and streams, which can lead to cumulative adverse effects (CAE).
This webinar provided an introduction about how CAE can be conceptualized, the language used to discuss CAE, and the legal basis for CAE. The presentation discussed a framework for considering adverse effects, including a review of general approaches for CAE assessments and ways to address these effects. The webinar concluded with the presentation of a thought-provoking approach to conducting simple assessment of CAE that could be adapted for use by wetland professionals as they work to identify and address CAE for projects they are planning and/or permits they are reviewing. The webinar ended with information about the Association of State Wetland Managers’ recent pipeline permitting project and forthcoming resources on CAE that will be available on ASWM’s website.

A Resources-Sensitive Approach to Riparian Management
Wednesday, June 25, 2025 - 3:00 p.m. - 4:00 p.m. EDT
- Tracey Miller, University of Kentucky
ABSTRACT
Riparian corridors are considered among the most productive ecosystems in the U.S. because of their influx of nutrients and life-sustaining water resources. Additionally, there is a positive relationship between the condition and function of wetlands and watercourses and the structure of the upland tree canopy. Unfortunately, increases in riparian imperviousness, poor vegetation, and high degrees of disturbance due to land clearing for agriculture and urban expansion are still among the nation’s most widespread stressors to wetlands and watercourses. Nevertheless, averting critical losses in biodiversity is still possible through intensified improvements in wetland management efforts, especially regarding riparian tree canopy density. Past scientific studies concerning silviculture practices in naturalized areas have identified an optimal balance of approximately 50% open sunlight and 50% dappled shade to support stream integrity. However, less information is available on the relationship between riparian tree canopy density and wetland and watercourse integrity along urban-rural gradients.
Using Connecticut’s municipal management system as an example, this webinar will identify optimal relationships between riparian tree canopy density and the integrity of wetlands and watercourses within the milieu of increasing urbanization across the state. The project uses ArcGIS spatial statistics tools and 30-meter landcover data to identify optimal riparian tree canopy density within a 300’ statewide riparian buffer over ten years. The project also illustrates how wetland managers can improve decision-making regarding tree removal on wetland applications by using Google Maps to evaluate existing vs. proposed riparian tree canopy density on site-specific projects as compared with these research findings.

NAWM Joins Several Environmental Organizations in Letter to Trump EPA Transition Team
NAWM and nine other environmental nonprofit or state organizations sent a letter to the Trump U.S. EPA Transition Team. The letter introduced the Transition Team to the national organizations that represent EPA’s state, tribal, and local partners, and offered assistance as the Administration advances an agenda to fulfill the critical mission of EPA to protect public health and the environment. In particular, the letter noted that environmental laws frequently establish state, tribal, and local governments as co-regulators who are the primary implementers of the nation’s environmental laws, regulations and policies. As a result, the letter urges that proposed changes to applicable EPA regulations be developed in collaboration with co-regulators. Read letter here.
MISSION
The mission of the National Association of Wetland Managers (NAWM) is to build capacity for state and tribal members and foster collaboration among the wetland community of practice by encouraging the application of sound science to wetland management and policy, promoting the protection and restoration of wetlands and related aquatic resources, and providing training and education for members and the general public.
VISION
As a result of NAWM’s work, the wetland community has access to and effectively uses sound science, policy, and private/public partnerships to preserve, protect, and restore the nation’s precious and limited wetlands and related aquatic resources.
HISTORY
The National Association of Wetland Managers (NAWM) was founded by Jon A. Kusler, Esq., Ph.D., and Scott Hausmann in 1983 with two goals — to support state wetland programs and to support national wetland policy reflecting sound wetland science. NAWM has tried to stay true to these goals throughout the years, during the ups and downs of funding and politics. Read more.
