SUPPLEMENTARY INFORMATION:

Background

    Wetland habitat in the Prairie Pothole Region (PPR) of Iowa, 
Minnesota, Montana, North Dakota, and South Dakota is important to 
waterfowl and other migratory bird populations. The unique topography 
of the PPR includes numerous small wetlands and potholes that were 
formed through glaciation thousands of years ago. Prairie potholes are 
freshwater depressions and marshes, often less than 2 feet deep and 1 
acre in size, that are a permanent feature of these landscapes barring 
deliberate alteration of the topography or hydrology. The seasonal 
fluctuation of surface water through these permanent wetlands basins 
makes the PPR biologically important to waterfowl. The PPR is 
responsible for producing approximately 50 to 75 percent of the primary 
species of ducks on the North American continent, providing habitat for 
more than 60 percent of the breeding population. Waterfowl fledged in 
the PPR are a significant natural resource that supports waterfowl 
hunting and an associated industry that creates an estimated 30,000 
jobs and nearly $1 billion in economic benefit.
    Congress officially created the Small Wetlands Acquisition Program 
on August 1, 1958, by amending the 1934 Migratory Bird Hunting Stamp 
Act (commonly referred to as the Duck Stamp Act; 16 U.S.C. 718-718k). 
The amendment allowed proceeds from the sale of Federal Duck Stamps to 
be used to conserve and protect ``small wetland and pothole areas'' 
through the acquisition and establishment of areas designated as 
waterfowl production areas (WPAs). The Service purchased the first fee-
title WPA in South Dakota in 1959 and began to purchase wetland 
easements soon thereafter.
    A wetland easement is a voluntary legal agreement wherein the 
Service makes a one-time payment to landowners to permanently protect 
wetlands located on their property. Currently, each easement purchased 
is annotated on a map that is properly recorded as a legal instrument. 
Easements purchased prior to 1976 were not mapped at the time of 
purchase but have been after the initial purchase. The easement 
contains restrictions on the use or development of the land to protect 
its conservation values. The Service's wetland easements are intended 
to be minimally restrictive meaning that they have a minimal impact on 
the property value and limited impact on the landowner's use and 
enjoyment of the property. Landowners who sell a wetland easement to 
the Service agree that wetlands protected by an easement cannot be 
drained, filled, leveled, or burned. If these wetlands dry up 
naturally, they can be farmed, grazed, or hayed. However, the Service 
also places restrictions on how landowners may utilize lands not 
covered by the wetland easement in order to avoid adverse impacts to 
the easement-covered wetlands allowing the Service to regulate a larger 
property interest than it acquired. The Service is seeking to strike 
the right balance between preserving the wetland interests it has 
legally acquired and recognizing the property rights retained by the 
landowner.
    The acquisition of wetland easements accelerated across the PPR 
following the passage of the 1961 Wetlands Loan Act (Pub. L. 87-383), 
which authorized appropriations to advance funding for the purchase of 
wetland easements. Wetland easements are part of the National Wildlife 
Refuge System, governed by the National Wildlife Refuge System 
Administration Act (16 U.S.C. 668dd et seq.).
    Traditionally, the purpose of subsurface agricultural drainage has 
been to lower the water table of poorly drained soils with the goal of 
improving soil aeration. Recently, advanced drainage systems have been 
promoted as a way to manipulate soil water content during the growing 
season. Subsurface drainage systems typically remove water through 
perforated pipe (commonly referred to as drain tile) placed below the 
soil surface.
    Drain tile positioned adjacent to wetland areas can result in 
reduced hydroperiods (periods of inundation) depending on several 
factors, such as the depth of tile in relation to the wetland area. The 
amount and timing of precipitation intercepted by subsurface drainage 
systems will vary depending on soil properties, topography (low/high 
topographic relief), placement of tile relative to the wetland area 
(horizontal distance, elevation), and the relation between the wetland 
area and groundwater (i.e., recharge, discharge). Direct drainage of a 
wetland area by placing perforated tile and surface inlet pipes through 
(beneath) the wetland area would have a detrimental effect on wetland 
hydrology regardless of other factors.
    Drain tile setback distances and easement conditions vary widely 
because they depend on the specific soils, topography, and wetland 
characteristics of each site. Drainage systems placed near a wetland 
can

[[Page 46797]]

influence how water moves toward or away from that wetland, but the 
extent of this influence changes from one easement to another. In low-
relief areas, drain tiles may draw groundwater laterally toward the 
pipe, while in higher-relief areas, drainage tile systems may intercept 
water flowing toward the wetland. Because these factors differ across 
the landscape, the potential effects of drainage and the resulting 
setback calculations are determined by the unique environmental 
conditions of each easement. Many property owners take issue with the 
fact they are not compensated for the loss of the use of their private 
property outside the easement that was originally purchased based on 
the area that is determined by the Fish and Wildlife Service as needed 
to stop drainage of the wetland. In most cases these drain tile setback 
distances were not provided to the landowner at the time the easement 
was purchased. In these cases, the landowner believed he was agreeing 
to limit his use of the land within the easement boundary itself.
    On May 13, 2024, the Service issued a final rule that codified the 
process by which landowners could request, and the Service would 
provide drain tile setbacks under wetland easement contracts (89 FR 
41336). This rule was effective on June 12, 2024. The regulations 
applied only to setbacks provided by the Service beginning on the 
effective date of the 2024 rule. See the 2024 rule for a complete 
discussion on the history of the PPR, wetland easements, and drain tile 
setbacks.
    Prior to finalizing the 2024 rule, the Service issued both internal 
setback guidance for administering drain tile setback requests and 
calculating drain tile setback distances, as well as a February 2020, 
guidance memo, ``Drain Tile Setbacks and Legal Action on U.S. Fish and 
Wildlife Service Wetland Easements.'' For a full discussion of the 
guidance memo and its key aspects, see the 2024 rule (89 FR 41336 at 
41337, May 13, 2024).

Purpose of This Request for Information (RFI)

    The purpose of this RFI is to gather information pertaining to 
easement lands protected by a Service easement for waterfowl management 
(commonly referred to as a wetland easement) in the PPR, and how the 
Service should calculate drain tile setbacks when requested to do so by 
a landowner. The Service especially invites information regarding:
     Efficacy of the 2024 rule ``National Wildlife Refuge 
System; Drain Tile Setbacks'' (89 FR 41336, May 13, 2024).
     How the current rule did or did not work as intended.
     How the Service should calculate drain tile setbacks when 
requested by a landowner.

Request for Information

    The Service invites the public to provide information on any aspect 
of the Service's 2024 regulation pertaining to drain tile setbacks on 
lands covered by wetland easement contracts, or the process by which 
the Service calculates recommended setbacks. Commenters may respond to 
the questions above or provide other relevant information. Submitters 
are encouraged to provide specific examples, geographies, dates, and 
any relevant supporting materials.

Public Availability of Comments

    All information received in response to this RFI will be posted on 
https://www.regulations.gov and may include personal identifying 
information. Do not include information you do not wish to make 
publicly available.

Authority

    The authority for this RFI is the National Wildlife Refuge 
Administration Act of 1966 (16 U.S.C. 668dd et seq.), as amended by the 
National Wildlife Refuge System Improvement Act of 1997 (Pub. L. 105-
57), governing the administration and public use of refuges.
