                       WEDNESDAY, APRIL 26, 2017

                                       U.S. Senate,
                 Committee on Environment and Public Works,
                                                    Washington, DC.
    The committee met, pursuant to notice, at 10:19 a.m. in 
room 406, Dirksen Senate Office Building, Hon. John Barrasso 
(chairman of the committee) presiding.
    Present: Senators Barrasso, Carper, Inhofe, Fischer,

Booker, Duckworth, and Harris.

           OPENING STATEMENT OF HON. JOHN BARRASSO, 
             U.S. SENATOR FROM THE STATE OF WYOMING

    Senator Barrasso. Good morning. I call this hearing to 
order.
    On February 28th, President Trump signed an Executive Order 
directing EPA and the Army Corps of Engineers to review the 
Obama administration's Waters of the United States, or WOTUS 
Rule, and to publish a proposed rule that would rescind or 
revise that rule. While this action was both correct and 
important, the long saga of the WOTUS Rule is not yet over. 
This fundamentally flawed rule is still on the books and needs 
to be withdrawn.
    The Supreme Court has decided to rule on whether or not 
circuit courts have the jurisdiction to hear challenges to the 
Rule. If the Supreme Court decides that these cases belong in 
district courts, then the nationwide stay that the Sixth 
Circuit Court of Appeals issued will go away.
    If that happens, this Rule, that is terrible and unlawful, 
will go into effect and the EPA and the Corps will be able to 
regulate isolated ponds and dry streambeds that have no impact 
on navigable water and were never intended to be covered under 
the Clean Water Act.
    As we will hear from our witnesses today, the justification 
for withdrawing the Rule is overwhelming. General Peabody is a 
decorated retired member of the military who was the Commanding 
General for the Civil and Emergency Operations at the Corps of 
Engineers until he retired in the fall of 2015. He will tell us 
that the definitions in the WOTUS Rule are not based on the 
Corps' expertise and experience. In fact, the Corps was shut 
out of the process of writing the final Rule and the support 
documents for the final Rule.
    The Corps is the agency that performs the on-the-ground 
inspections that identify what water is federally regulated. If 
the Rule is not based on their experience, that means it has no 
technical basis; it is, instead, a blatant government power 
grab.
    Dr. Josselyn is a Ph.D. and a professional wetlands 
scientist who was a member of the Science Advisory Board Panel 
that was put together by the EPA that reviewed EPA's ``Science 
Report.'' This report is a scientific literature review on 
water connectivity.
    The Obama EPA claimed that the WOTUS Rule is based on the 
conclusions of this report. Dr. Josselyn will tell us that, in 
fact, this report does not address the issue of where Federal 
regulators should establish jurisdiction.
    EPA Science Report looks at connections to water, but fails 
to examine whether connections are significant, and most of the 
studies in the report do not address navigable water. Instead, 
this report concludes that all water is connected. Our children 
learn that in fourth grade when they learn about the water 
cycle. That has nothing to do with Federal jurisdiction, and it 
means that the EPA's Science Report can not be used to justify 
the WOTUS Rule.
    Mr. Tseytlin is the Solicitor General for the State of 
Wisconsin and he works with the 31 States that are all 
challenging the WOTUS Rule. Mr. Tseytlin will tell us that the 
final rule included new definitions that were created without 
public input and even without public notice. This means that 
the WOTUS Rule is arbitrary and capricious, and violates the 
Administrative Procedure Act.
    We also will hear from Mr. Kopocis. He was the Deputy 
Assistant Administrator for the Office of Water in the Obama 
administration. He will tell us that the Obama administration 
met with States and other stakeholders during the rulemaking 
process. That does not change the fact that between the 
proposed Rule and the final Rule the Corps was arbitrarily or 
deliberately shut out of the process. The end result is the 
Obama administration wrote a RULE that is not supported by 
agency expertise, by agency experience, or by the science or 
the law.
    Finally, we will hear from Mr. O'Mara, who is President and 
Chief Executive Officer of the National Wildlife Federation. 
The National Wildlife Federation is very interested in 
protecting wildlife habitat. The right way to do this is to 
form partnerships with landowners, not to expand Federal 
control over private property. In fact, in 2014, the Fish and 
Wildlife Service issued a report that notes that the Service 
works with landowners to employ cooperative conservation 
measures to preserve isolated wetlands like prairie potholes, 
measures that let farming continue.
    If the WOTUS Rule goes into effect, instead of working 
cooperatively, the Federal Government could simply take control 
of private land and shut down farming activity. We have already 
had attempts to do this in my home State of Wyoming, where Mr. 
Andy Johnson, who EPA threatened to fine $37,500 a day for 
simply building a stock pond on his property.
    After looking at this record, the only course of action 
that makes sense is to withdraw the Rule and start over. I hope 
we can see quick action to lift this threat to farmers and 
other landowners that have been created as a result of the 
WOTUS Rule.
    I now turn to Ranking Member Carper for his testimony.

          OPENING STATEMENT OF HON. THOMAS R. CARPER, 
            U.S. SENATOR FROM THE STATE OF DELAWARE

    Senator Carper. Thanks, Mr. Chairman. Thanks for bringing 
us all together.
    I spoke with the witnesses before we began and I said, this 
is an issue, as you are going to hear from the Chairman's 
opening remarks, that brings out strong feelings on several 
sides. One of the things that I hope might happen here today is 
that the panel this diverse and this smart could actually help 
provide some consistency and maybe some consensus before we 
walk out of the room, so thank you all for joining us.
    This hearing also represents a valuable opportunity to 
consider the critical elements of any sound rulemaking to 
address the definition of water that receives Federal 
protection, including rulemaking that would be required to 
rescind the rule that we are considering today. Fortunately, we 
have a panel of experts to help us sort through the nuance of 
law and science. We welcome all of you very much, appreciate 
your contributions to our discussion. Before we dive into the 
details, though, I would like to step back just a little bit 
and recall how we got to this point with the definition of 
waters of the U.S.
    You will recall that the passage of the Clean Water Act was 
a product of horrific water quality in many parts of the 
Country. I went to Ohio State University, and just north of us, 
in Cleveland, there is a river flowing through Cleveland that 
caught on fire. It was not just the Cuyahoga River that was 
contaminated, there were a lot of others as well. Frankly, 
there still are too many. There was broad, national concern 
over the State of our waters then, and there was consensus that 
we needed to do something comprehensive to fix the problem.
    Congress was not confused or uncertain about what it was 
seeking to protect when it passed the Clean Water Act in 1972. 
The first sentence of that Act passed in 1972 says this: ``The 
objective of this chapter is to restore and maintain the 
chemical, physical, and biological integrity of the Nation's 
waters.'' That is what it says. When Congress reported out that 
legislation, this Committee acknowledged that ``it is essential 
that discharges of pollution be controlled at the source. At 
the source. The Act defined the term ``navigable waters'' 
broadly, as ``all the waters of the United States.'' Congress 
clearly understood that cleaning up our waters involved 
controlling pollution discharges in a lot of places where ships 
do not go.
    While broad, the coverage of the Act was clear. While 
demanding on cities and industries, farmers, ranchers, and 
developers, the benefits of the Act were dramatic. More than 60 
percent of the lakes and 55 percent of the rivers were able to 
achieve the Act's water quality goals of being fishable and 
swimmable by the year 2003.
    I believe that all of us understand that protecting 
wetlands and reducing pollution requires active participation 
from farmers and ranchers. They live closest to our land and to 
our waters, and they have every reason to be good stewards of 
these resources; and for the most part they are, really good 
stewards in most cases. Indeed, that is one reason why farmers 
in my State of Delaware celebrate their investments in, and 
successes of, no-till farming and all other kinds of 
conservation measures that I will not get into today.
    While those farmers love their land, traditional farming 
practices often ended up sending some of their best soils down 
a ditch or maybe away with the breezes on a windy day. Their 
land was eroding from under their feet. Then science showed 
them a better way. They were not blinded by science; they were 
guided by science. Their commitment to the land and their 
livelihoods allowed them to embrace new practices that preserve 
their future and a foundation of rural life and the economy. I 
think we need that sort of agreement for clean water, along 
with a commitment to make this collective effort as 
predictable, simple, and inexpensive as possible.
    No one was pleased with the confusion, uncertainty, and 
burdensome bureaucratic processes resulting from the Supreme 
Court's decision in the 2001 SWANCC case and 2006 Rapanos case. 
Without the Clean Water Rule, though, EPA and the Corps of 
Engineers would have to undertake a burdensome, time-consuming, 
expensive, unpredictable, and confusing process to determine 
what is covered by the Clean Water Act and what is not. That is 
no way to do business, which is exactly why there was broad and 
diverse interest in having both the EPA and the Corps develop 
clear guidance, through regulation, to cut through the morass. 
That, I believe, is the motivation behind, and I think the 
result of, the Clean Water Rule.
    If I were to take on that very important task, here are 
some things that I would want to focus on: I would analyze all 
the peer-reviewed science I could get my hands on; I would host 
hundreds of public meetings across our Country; I would ensure 
that all who wish could have their say; I would review a 
million comments, if I had to; and I would consult with the 
States, with affected industries, with farmers, with fishermen, 
and the best water minds around. That is exactly what went into 
developing the Clean Water Rule that we are discussing today.
    To tell you the truth, I do not believe that I have ever 
met anyone who thinks the Rule is perfect. I do not, and I have 
not met anyone who thinks that it is. It is too hot for some, 
too cold for others, but it will protect the water we all need.
    The Rule has been a long time coming, as you know. It is 
well informed by science and by experience, it treads a 
moderate line between the extreme desires of interests at both 
ends, and it is the product of a massive public engagement 
effort. I would ask this Administration and detractors of this 
approach to show us your work. Just show us your work. Give the 
rest of us the same rigor, the thoughtfulness, the engagement, 
the transparency, and science that underlies this effort, and 
show us, with the same degree of dedication to the task, to the 
law, and to our health and environment, that you have something 
better to offer. Otherwise, I am afraid that you risk, you 
being the Administration, risk failing all of our people and 
spending an awful lot of time and taxpayer money subsequently 
in court. This Rule has all the basis in law, has technical 
merit, and the science that it needs.
    Thank you, Mr. Chairman. I would ask unanimous consent, if 
I could, to insert into this hearing record letters that I 
received from The Southern Environmental Law Center and Clean 
Water Action supporting the Clean Water Rule. Thanks so much.
    Senator Barrasso. Without objection, those are admitted to 
the record.

    Senator Barrasso. Thank you very much, Senator Carper.
    We will now hear from our witnesses. I would like to remind 
the witnesses that your full written testimony will be made 
part of the official record today. I please ask that you keep 
your statements to 5 minutes so that we may have some time for 
questioning. I look forward to hearing the testimony of each 
and every one of you, and I would ask Major General John 
Peabody to begin.
    Thank you so much for being here.

         STATEMENT OF MAJOR GENERAL JOHN PEABODY (RET.)

    General Peabody. Thank you, Mr. Chairman, Mr. Ranking 
Member. I appreciate the invitation to appear here today.
    I am testifying based on my personal knowledge related to 
the Waters of the United States, or Clean Water rulemaking, 
while serving as the Deputy Commanding General for Civil and 
Emergency Operations in the Army Corps of Engineers from 
October 2013 through August 2015. I retired 20 months ago, so I 
am testifying as a private citizen who does not speak today for 
the Corps in any way. However, my testimony reflects my best 
recollection of this rulemaking process and the professional 
advice I received from Corps experts during that period.
    The Corps is the primary agency responsible for 
administering Section 404 of the Clean Water Act through more 
than 1,200 Corps regulators who process over 99 percent of all 
Section 404 actions in this Country, consisting of tens of 
thousands of regulatory actions each year. Contrary to common 
belief, the vast majority of all applications, about 80 
percent, receive a decision within 60 days from receipt of a 
policy-compliant application.
    Corps professionals are the face to the public regarding 
this program across many different circumstances involving a 
complex array of multiple environmental and administrative 
laws, policies, and procedures. In my opinion, the Corps' 40-
plus years of experience involving over 2 million actions--that 
is my estimate--make it the best organization to advise 
policymakers on what should constitute waters of the United 
States.
    Beginning in November 2014 and continuing through the 
Rule's finalization in May 2015, Corps involvement in the 
rulemaking was limited to a few engagements primarily regarding 
discreet aspects of draft Rule language. In that period, the 
Corps did not regularly or substantially participate in draft 
final Rule changes as they occurred, was excluded from routine 
Rule text development and policy discussions, had little direct 
engagement with EPA counterparts, and was only engaged by those 
developing the Rule on a periodic and constrained basis.
    I do not consider the Corps to have been a member of a 
collaborative and substantive joint process that included 
serious consideration of Corps concerns and recommendations. On 
the contrary, in my opinion, Corps involvement was superficial 
during that period.
    Despite this, Corps staff made every effort to propose 
options that would address policy considerations and ways that 
met central characteristics: that it be one, scientifically 
based, two, technically implementable, and three, legally 
defensible. These three criteria, and the duty to ensure 
policymakers clearly understood the implications of the Rule 
language, were the only motivation behind my personal actions.
    The Corps' key concerns centered on new definitions, terms, 
and approaches in the draft final Rule that would cause changes 
to jurisdictional scope, as compared to the 2013 proposed Rule 
and then currently operating procedures. These key concerns 
addressed the subjects of tributaries, other waters, adjacency, 
neighboring isolated water bodies, the 4,000-foot 
jurisdictional limit, and ditches, among others. These concerns 
went largely unaddressed.
    Further, it was the Corps judgment that key policy 
decisions, especially the 4,000-foot jurisdictional limit, but 
also decisions related to the definition of tributaries and the 
treatment of isolated water bodies, were not based on 
scientific analysis contained in the Connectivity Report, nor 
part of the proposed Rule that was available for public 
comment.
    When the final draft Rule and Preamble were provided for 
interagency coordination in early April 2015, Corps staff 
discovered that the final Rule still did not address these key 
concerns. The Preamble also mischaracterized the Corps as 
jointly developing the Rule and as supporting its key 
judgments. This is inaccurate.
    A few weeks later, the technical support document and 
economic analysis were published, and had analyzed Corps 
technical data without Corps involvement. In broad terms, they 
both misapplied Corps data out of context to generalize broad 
nationwide conclusions unsupported by the underlying data.
    Corps experts believed the draft final Rule and supporting 
documents were so untenable, I asked Corps staff to provide a 
thorough, but rapid, analysis of only those issues in the Rule 
documentations which they identified as potential fatal flaws. 
Given limited Corps involvement during the rulemaking and the 
Corps judgment that the Rule was fatally flawed, I became 
unsure whether we had adequately conveyed Corps concerns to the 
policymakers. The internal deliberative memoranda I forwarded 
to the Secretary were intended to fulfill my duty to be certain 
to communicate the Corps' serious concerns clearly and 
unambiguously before an irreversible final decision.
    In my professional opinion, this Country and Federal 
regulators like the Corps need clear, objective, bipartisan 
policy direction that is well founded on facts, science, 
appropriate expertise, and clearly articulated laws, 
regulations, and policies.
    It remains my sincere hope that this Nation's policymakers, 
including this Committee, can find common ground based on 
science and objective analysis to develop a bipartisan solution 
on this important and, in my judgment, much needed matter. I 
hope that my testimony has provided some value for the 
Committee and I thank you for your time.
    [The prepared statement of Mr. Peabody follows:]
    [GRAPHICS NOT AVAILABLE IN TIFF FORMAT]
    
    Senator Barrasso. Thank you very much, General Peabody. We 
appreciate your comments and your testimony. Appreciate it.
    Next I will turn to Michael Josselyn, who is a Principal at 
Wetlands Research Associates, San Rafael, California.
    Thanks so much for being with us today. We appreciate you 
coming and we look forward to your testimony.

STATEMENT OF MICHAEL JOSSELYN, PH.D., PWS, PRINCIPAL, WETLANDS 
                      RESEARCH ASSOCIATES

    Mr. Josselyn. Thank you, Mr. Chairman, Mr. Ranking Member, 
and members of the Committee. I am Michael Josselyn, Founder 
and Principal with the environmental consulting firm Wetlands 
Research Associates, with offices throughout California and in 
Colorado. I am primarily responsible for assisting our Federal 
and State private clients in compliance with Section 404 of the 
Clean Water Act, and I have 38 years of experience and am a 
Certified Professional Wetlands Scientist.
    I served on the Environmental Protection Agency's Science 
Advisory Board Expert Panel to review the EPA's Connectivity 
Report which was prepared during the rulemaking process for the 
2015 WOTUS Rule. I want to make three points in my introductory 
remarks.
    First, the Panel's focus was on the Connectivity Report and 
whether the Report reflected the current status of the science 
on rivers, streams, and wetlands. We were charged with making 
recommendations to improve and clarify the Report. The draft 
Report confirmed the basic hydrologic principle that all parts 
of a watershed are connected to some degree.
    The Panel was not tasked, nor did it consider, the policy 
and legal questions on which waters should be federally 
regulated. The Panel made numerous recommendations on the 
content and interpretation of the literature. The Panel asked 
the EPA to evaluate the strength of the literature in various 
topic areas and the uncertainty associated with it.
    As you can see from the table here on my right that was 
published in the final Report, the scientific literature is 
strongest for those drainages that have perennial and 
intermittent flows as being connected, as shown by the larger 
dots on the chart. The effect to downstream waters is less 
known for intermittent streams.
    We also know a great deal about riparian wetlands, that is, 
wetlands that are directly connected to rivers. When it comes 
to ephemeral streams and non-floodplain waters, the literature 
is very limited, as shown at the bottom of the graph in the 
small dots.
    The final Report is an encyclopedia of what we know about 
the science, but is also limited by what we do not know.
    Second, the Panel found that ``the review of the scientific 
literature strongly supports the conclusion that streams and 
bidirectional floodplain wetlands are physically, chemically, 
and/or biologically connected to downstream navigable waters; 
however, these connections should be considered in terms of a 
connectivity gradient.'' The presence of a gradient that 
defines the effects on downstream waters became a foundational 
element in the discussions by the Panel. The Panel stated that 
connectivity should ``recognize variation in frequency, 
duration, magnitude, predictability, and consequences of these 
connections'' and developed a figure as to what that meant. 
This is the figure that I am showing right now that was 
published in the science report.
    In the upper portion of the figure, the Panel concluded 
that there was a high probability, as shown by the width of the 
blue bar, that perennial streams and intermittent streams will 
have a high degree of connectivity to downstream waters given 
their high frequency and duration of flow, and the amount of 
material that could be transported to those waters.
    Similarly, for biological factors, the scientific evidence 
shows that perennial and intermittent streams transported 
materials downstream are also high, but had considerably less 
probability associated with ephemeral streams. Importantly, as 
the frequency, duration, and magnitude of flows decrease, 
ephemeral streams, as shown as you move to the side where the 
smaller arrow, that the probability for an effect on the 
downstream waters is much lower, as the chart states, and may 
not have a discernible effect.
    The Panel repeatedly recommended that the EPA develop more 
quantitative measures and criteria to assess this connectivity 
gradient. The Panel concluded that although connectivity is 
known to be ecologically important, the frequency, duration, 
predictability, and magnitude of connectivity will ultimately 
determine any consequences to downstream waters.
    Third, there are a number of concepts and issues included 
in the WOTUS Rule that were not elements of the Panel's review. 
For instance, distances set by the WOTUS Rule were not 
considered by the Panel and, in fact, the Panel stated distance 
should not be used as a metric for determining connectivity. 
Furthermore, the approach set forth in the WOTUS Rule for 
determining significant nexus is based on the selection of any 
one function and does not consider the connectivity gradient 
discussed in the Panel's report and shown on this graph. 
Finally, the Panel did not review, nor did the Connectivity 
Report discuss, the aggregation methods in which similarly 
situated tributaries would be combined in order to reach a 
significant nexus finding.
    In my experience in making jurisdictional determinations, 
these elements of the WOTUS Rule have the effect of expanding 
the scope of jurisdiction compared to past guidance by the 
Corps and the EPA.
    Thank you.

    Senator Barrasso. Thank you so very much for your 
testimony. We appreciate you being here with us today, Mr. 
Josselyn.
    I would like to now turn to Misha Tseytlin, who is the 
Solicitor General for the State of Wisconsin, from Madison, 
Wisconsin. I appreciate you making the trip to Washington, 
being with us, and I look forward to your testimony.

   STATEMENT OF MISHA TSEYTLIN, SOLICITOR GENERAL, STATE OF 
                           WISCONSIN

    Mr. Tseytlin. Thank you, Chairman Barrasso, Ranking Member 
Carper, and members of this Committee. I am grateful for the 
opportunity to appear before you today. My name is Misha 
Tseytlin and I serve as the Solicitor General for the State of 
Wisconsin.
    My State, led by Attorney General Brad Schimel, has played 
an important role in the multistate coalition litigating 
against the WOTUS Rule. Our 30-state coalition is broad and 
geographically diverse, comprising States from Wyoming to West 
Virginia, from Ohio to Oklahoma, from Alabama to Alaska and 
beyond.
    The reason for the breadth of this coalition, to my 
knowledge, the largest such coalition challenging any 
regulation issued by the prior administration, is that the 
WOTUS Rule is a deeply intrusive invasion upon traditional 
State authority. Under both the United States Constitution and 
the Clean Water Act, States have the lead role in regulating 
most waters and lands within their borders. The Clean Water Act 
states this explicitly, explaining that it is ``the primary 
responsibility and rights of States to plan the development and 
use of land and water resources.'' The Federal Government, in 
contrast, only has limited authority to protect the Nation's 
``navigable waters.''
    The WOTUS Rule is an overbroad assertion of Federal 
authority over local waters, which are rightfully subject to 
State, not Federal, regulation. The Rule claims Federal power 
over streambeds that are dry most of the year and water 
features connected to navigable waters only once every 100 
years. I think a small example will illustrate this point. If 
you are a Wisconsin farmer and you have a small pond on your 
land, that pond is automatically subject to Federal 
jurisdiction if, after a once-in-a-century rainstorm, that pond 
is within five football fields of any tributary, any navigable 
water.
    This Rule was also adopted without meaningfully consulting 
the States about their water protective programs. Such 
consultation would have revealed that States already protect 
these local features, making Federal regulation unnecessary. 
Indeed, I would argue that the process that led to the adoption 
of the WOTUS Rule involved one of the most significant 
procedural failures in the history of the Administrative 
Procedures Act.
    Earlier testimony from General Peabody demonstrated how EPA 
cut the Corps out of the process of designing the WOTUS Rule. 
That is just the tip of the iceberg. EPA cut the entire public, 
including the States, out of that process. That is because the 
final Rule that the Agency adopted departed very significantly 
from the proposed Rule, in a way that the public had no idea 
about and was not informed about. In particular, EPA formulated 
many of the central concepts of the Rule behind closed doors 
and sprang them on an unsuspecting public without public input.
    The lack of record support and procedural illegalities of 
the WOTUS Rule can be summarized with one simple point. When 
the prior administration filed its 245-page brief before the 
Sixth Circuit seeking to defend the Rule, it could not cite a 
single public comment on the central features of the WOTUS 
Rule's adjacency or case-by-case waters category, either for or 
against. That is because EPA simply invented those central 
concepts of the WOTUS Rule out of whole cloth, without any 
record support or without any public input. That is against the 
law.
    It is, thus, unsurprising how poorly the WOTUS Rule has 
fared in court. On October 9th, 2015, our broad coalition of 
States secured a nationwide stay of the WOTUS Rule from the 
United States Court of Appeals for the Sixth Circuit. As the 
Sixth Circuit explained, the States demonstrated that they had 
a ``substantial possibility of success on the merits'' in their 
arguments that the WOTUS Rule violated the Clean Water Act and 
violated the EPA. The United States District Court for the 
District of North Dakota reached the same conclusion and thus 
issued a preliminary injunction blocking the WOTUS Rule.
    Our coalition of States was extremely pleased that the new 
Administration heeded the message of the Federal courts and has 
moved forward with rescinding the Rule.
    The work that this Committee is doing here today provides a 
valuable public service. Given the current Administration's 
laudable and swift movement toward repealing the WOTUS Rule, 
the Federal courts are unlikely to have an opportunity to 
declare, finally, what the Sixth Circuit and the District of 
North Dakota concluded preliminarily: the Rule is unlawful. 
This hearing is therefore vital to establish for the public 
what the States were already well on their way to proving in 
court.
    Thank you for the opportunity to testify before you today. 
I look forward to answering any questions you may have.
    [The prepared statement of Mr. Tseytlin follows:]

    Senator Barrasso. Thank you very much, Mr. Tseytlin. We are 
very grateful for your testimony.
    I would like to now turn to Ken Kopocis, who is Assistant 
Professor, American University Washington College of Law, 
Washington, DC.
    Thank you very much for joining us today.

    STATEMENT OF KEN KOPOCIS, ASSOCIATE PROFESSOR, AMERICAN 
              UNIVERSITY WASHINGTON COLLEGE OF LAW

    Mr. Kopocis. Thank you. Chairman Barrasso and Ranking 
Member Carper, thank you for the request to appear today to 
discuss the Clean Water Rule, a rule issued jointly by the U.S. 
Environmental Protection Agency and the Department of the Army 
to clarify the scope of the Clean Water Act. I appear today in 
my personal capacity.
    In 1972, Congress enacted the Clean Water Act and made 
clear that the objective of restoring and maintaining the 
Nation's waters would best be achieved by controlling 
pollutants at their source. The Clean Water Rule assists that 
effort by making the scope of the Clean Water Act easier to 
understand, more predictable, and more consistent with the law 
and peer-reviewed science. The Rule interprets the Clean Water 
Act; it does not expand it.
    It is critical to note that the Clean Water Act permitting 
requirements are triggered only where there will be a discharge 
of a pollutant into a jurisdictional water. If a jurisdictional 
water is not going to be polluted or destroyed, the Clean Water 
Act does not affect the use of that water.
    The Supreme Court has considered the scope of waters 
protected by the Clean Water Act from pollution and destruction 
three times: Riverside Bayview, SWANCC, and Rapanos. In each of 
those cases every Justice has supported that the term navigable 
waters applies to waters beyond those considered to be 
traditionally navigable.
    In Rapanos, no opinion could gather a majority, and the 
nine Justices wrote five separate opinions. That confusion 
evident on the Court carried over into the regulated community 
and the two agencies. In both SWANCC and Rapanos, the agencies' 
regulations were left intact by the Court.
    Interested parties demanded that the agencies take 
regulatory action to clarify which waters would have their 
water quality protected by the Clean Water Act and which would 
not. Every interest group that approached the agencies, and 
this includes agriculture, property development, environmental 
groups, resource extraction, hunters, fishers, 
conservationists, mayors, Governors, Federal and State 
legislators on both sides of the aisle, and countless others, 
all recommended that the agencies take action to address the 
post-Rapanos confusion. No one argued for the agencies to do 
nothing.
    In response, the agencies spent several years developing 
the Rule, and its development included countless conversations 
with all of the interested parties I previously mentioned.
    The Rule is informed and supported by the best available 
peer-reviewed science on the relationship of waters and the 
impacts of protecting water quality, or not protecting water 
quality, on downstream and adjacent waters. EPA's Office of 
Research and Development prepared an exhaustive synthesis of 
peer-reviewed science on how waters are connected to each other 
and how they impact downstream waters. The Science Report was 
peer-reviewed by EPA's independent Science Advisory Board and 
subject to public comment. Science was reviewed by the board, 
not policy.
    The final Science Report provides several key conclusions 
in support of the Rule. Additionally, the Science Advisory 
Board indicated that available science provided an adequate 
basis for key components of the Rule.
    The Rule recognizes three categories of jurisdiction: 
waters jurisdictional in all instances, but limited by 
definitions that address issues such as connectivity and 
significance of nexus; a narrow category of waters that will 
continue to be subject to case-specific significant nexus 
analysis of SWANCC and Rapanos; and an expanded list of waters 
that are excluded from jurisdiction. The Rule also establishes 
transparency and how the agencies will make significant nexus 
determinations, rather than leaving that to the discretion of 
an agency employee.
    Because of the Clean Water Rule's greater clarity and 
specificity compared to the rule it replaced, no longer would 
many waters need a time-consuming individual analysis to 
determine whether there was a significant nexus to a downstream 
jurisdictional water. The Rule carries forward the 
jurisdictional exclusions and adds several new ones. People 
would, for the first time, be able to read the Rule and better 
know that a water body or feature was not subject to the Act 
without the need for an expert or individual analysis.
    For greater detail on inclusions and exclusions, I attached 
the Rule to my testimony.
    The Clean Water Rule is a carefully considered rule that 
was developed with unprecedented public engagement and comment. 
It was available for public comment for over 200 days, and 
during that period EPA held over 400 public meetings and calls. 
I personally attended about 70 of those in my prior capacity.
    The Rule applies the law as written by Congress and 
interpreted by the Supreme Court. It relies upon the best 
available peer-reviewed science and it is a product of over 40 
years of technical expertise of the U.S. EPA and the Army, 
working with the Corps of Engineers on the Clean Water Act.
    Unfortunately, the Rule's benefits of clarity, 
predictability, and consistency have been put on hold by the 
Sixth Circuit, but that will ultimately be resolved. While I 
personally am very aware of the controversy surrounding the 
scope of the Clean Water Act, I also believe that it is a 
disservice to the public that the current Administration has 
indicated that it will undertake a new rulemaking to repeal and 
replace. That effort is guaranteed to continue the post-Rapanos 
confusion for many, many years to come.
    The work of the Clean Water Act is far from finished. 
State-generated water quality reports indicate hundreds of 
impaired waters in need of reduced pollution and increased 
protection. Narrowing the scope of the Act does not advance 
these joint Federal and State efforts.
    In my 30-plus years in water law, I have never heard that 
the water in our rivers, lakes, streams, and ponds is too 
clean; that there are too many healthy fish to catch and eat; 
that our drinking water is too clean and abundant; or that we 
need more beach closures due to pollution.
    The Clean Water Rule advances the cause of restoring and 
maintaining the integrity of our Nation's waters. Thank you 
again, and I am pleased to answer any questions you may have.
    [The prepared statement of Mr. Kopocis follows:]

    Senator Barrasso. Thank you, Mr. Kopocis, for being with us 
today and sharing your testimony.
    I would like to now turn to Collin O'Mara, who is the 
President as well as the Chief Executive Officer of the 
National Wildlife Federation from Reston, Virginia.
    Thank you very much for joining us. We look forward to your 
testimony.

    STATEMENT OF COLLIN O'MARA, PRESIDENT & CHIEF EXECUTIVE 
             OFFICER, NATIONAL WILDLIFE FEDERATION

    Mr. O'Mara. Thank you. Mr. Chairman, Senator Carper, 
members of the Committee, on behalf of our six million members 
of the National Wildlife Federation, our more than 50 State and 
territorial affiliates, our millions of hunters and anglers, 
thank you or holding this hearing and talking about ways we can 
improve water quality. We are committed to finding bipartisan, 
collaborative solutions to making sure that we avert the 
wildlife crisis that we are facing so we can all enjoy the 
great outdoors.
    I think we would all agree that clean water is absolutely 
essential for public health. It is essential for wildlife; it 
is essential for local economies. As I have traveled to all 50 
States across this Country, Americans of all backgrounds, of 
every zip code all agree that they are united on the need for 
safe drinking water and healthy rivers. We have seen, 
unfortunately, in the past few years what happens when we do 
not take care of our water supplies. We saw this in Flint, 
Michigan and Toledo, Ohio. We saw this in Eden, North Carolina 
and Charleston, West Virginia. We saw this in the Animus and in 
the Yellowstone River. Where I live in Delaware, more than 90 
percent of our waterways have excess nutrients and legacy 
pollution.
    One of the best ways to clean up America's waterways is to 
reduce pollution at its source. I think we knew this in 1972, 
when Ed Muskie was in this very Committee thinking about how to 
clean up America's waterways, and the National Wildlife 
Federation was proud to stand along at the Anacostia River, at 
the boathouse, as the Earth Conservation Corps, our D.C. 
affiliate, when the Clean Water Rule was finalized.
    Today I would like to cover four points about the Clean 
Water Rule: the underlying science of connectivity, the case 
law, the economic benefits, and the importance to wildlife and 
sportsmen.
    First, the science of connectivity. There is broad 
scientific agreement, as I think you have heard from this 
panel, that keeping America's rivers healthy starts upstream. 
Just like the tree that depends on its roots, the healthy river 
is tied to the health of the streams that feed into it. Aquatic 
systems are interrelated and interconnected, as Senator Howard 
Baker once said. This makes common sense. As this Chairman 
said, we learn this at an early age, about the water system and 
that the pollution enters into small tributaries and makes its 
way into the main stems. Pollution that is added to the 
Schuylkill River in Pennsylvania affects my Delaware River 
downstream. Nebraskans that depend on the Platte can not ensure 
the health of the Platte unless they reduce the pollution 
coming from Colorado through the Southern Platte tributary.
    As Wendell Berry once said, we should adopt the water 
golden rule, if you will: do unto those downstream as you would 
have those upstream do unto you. Cleaning up America's 
waterways has to start with headwaters and tributaries.
    Now, the Science Advisory Board overwhelmingly confirmed 
this fact, and I think you have heard this. Although there are 
disagreements about the gradients, there is broad consensus 
that the definition of navigable waterways needs to extend into 
these headwaters.
    That brings me to the law. EPA and the Army Corps developed 
the Clean Water Act because the Supreme Court directed them to 
do so. From both Chief Justice Roberts and Justice Breyer, they 
clearly called for the agencies to act in the Rapanos decision 
and in subsequent decisions, and there is agreement that the 
jurisdiction extends beyond just navigable waterways into these 
tributaries.
    The approach that is most widely accepted by the U.S. Court 
of Appeals is Justice Kennedy's significant nexus test. This 
requires showing the ecological linkages between smaller and 
more remote water bodies and the navigable waterways. The Clean 
Water Rule closely tracks Kennedy's test, grounding its 
definitions of which waters are included in its science-based 
finding to show the connectivity between tributaries to 
traditional navigable and interstate waters, wetlands and lakes 
and other water bodies that are adjacent to these tributaries 
that provide critical filtration.
    Also the Rule is very clear, both the Corps and the EPA 
were very clear about which waters are excluded and which 
activities are not under the jurisdiction of the Act. This 
clarification is incredibly important; it is actually essential 
to providing regulatory certainty. As the former Secretary of 
Natural Resources for the first State of Delaware, I can attest 
to the uncertainty on the ground and how the uncertainty leads 
to confusion because of the court decisions and the previous 
regulations that are just completely confounding to the average 
landowner.
    Businesses and landowners need predictability. They need a 
way to make decisions, and having these ambiguous decisions 
that they are trying to hire experts to hope that the 
recommendations are given will hold up in court is creating a 
lot of paralysis on the landscape. This Rule clarifies which 
waterways are covered and strengthens those exemptions in a way 
that is much more narrow than the scope of the included 
waterways prior to 2001.
    That brings me to my third point, which is economics. In 
addition to increasing predictability, the Rule supports 
America's $800 billion outdoor economy and the millions of jobs 
that depend on the health of American waterways. These jobs, 
retail outfitters, fishing and river guides, bate shops, 
hotels, restaurants, they are important in rural communities 
like where I grew up in upstate New York. Many of these 
communities are struggling with high unemployment and they 
depend upon healthy waters for boating, fishing, hunting, and 
wildlife watching. Fishing alone supports $200 billion in 
economic activity and 1.5 million jobs, and that requires clean 
water.
    Finally, for wildlife and sportsmen, clean water is 
exceptionally important. More than 50 million Americans, 
including many on this Committee, hunt and fish. It should come 
as no surprise that duck hunters and anglers care deeply about 
water quality. More than 8 in 10 hunters and anglers across 
this Country support Federal protections for smaller streams 
and wetlands. Further, restoring wetland and waterway health is 
an important way that we can proactively solve America's 
growing wildlife crisis and recovering aquatic species that are 
at risk of potential extinction, things like amphibians, 
bivalves, mussels, and oysters, and a range of freshwater fish.
    In conclusion, in our lifetime we have the potential to 
fulfill the promise of the Clean Water Act, when 45 years ago 
this Committee said that they were going to make sure that 
America's waters were fishable, swimmable, and drinkable. It 
will take a combination of common sense protections, as well as 
collaborative conservation efforts like the Chairman mentioned. 
We need things like good conservation programs in the Farm 
Bill, the State Revolving Funds, efforts like the Great Lakes 
Restoration Initiative, efforts like the Chesapeake Bay 
Program, the Delaware Bay Conservation Act.
    There are a lot of things that we need to do to make sure 
we are enhancing collaborative conservation. We also need 
common sense protections. The Clean Water Rule is an important 
part of this effort and it is a product of years of transparent 
scientific and public deliberations, and it protects the 
drinking water for more than 117 million Americans.
    Thank you for the time. We encourage you to support the 
Rule.
    [The prepared statement of Mr. O'Mara follows:]
   [GRAPHICS NOT AVAILABLE IN TIFF FORMAT]
    
    Senator Barrasso. Thank you very much for your testimony.
    I thank each and every one of you for being here today.
    We are going to ask the members now to join in the 
questioning, and I will start with you, Dr. Josselyn, if I may.
    We have gotten to the point where the WOTUS Rule is a 
punchline. As you can see, cartoonists are joking about 
navigable water on Mars. It says Nassau discovers evidence of 
flowing water on Mars, federally protected wetland, EPA, Clean 
Water Act advisory. Here we have this as a punchline because 
Mars has erosion features. Do a lot of other places. Water 
creates erosion when it runs downhill.
    The second picture is of a highway project in Indiana where 
the WOTUS sign, an Indiana highway project, it says: Notice 
Waters of U.S. It is an actual sign in Indiana. The contractor 
put up the sign because they were concerned that the EPA and 
the Corps would consider this hillside a water of the United 
States because the WOTUS Rule could regulate the hill as a 
tributary, as there are real streams somewhere maybe nearby. 
What you can see is the issue related to adjacent water.
    My question is does the EPA Science Report support the 
conclusion that these kinds of erosion features, both on Mars 
and here in Indiana, have a significant nexus to navigable 
water?
    Mr. Josselyn. Thank you, Senator. I look at that figure and 
I have to say that I have seen that similar situation in other 
areas of the U.S. where the EPA and the Corps have taken 
jurisdiction over what look like very ephemeral features.
    Obviously, the presence of an ordinary high water mark is 
the only indicator that they use there. As I testified, the 
science does not support that type of feature as having a 
significant nexus, and it goes back to the chart which I showed 
earlier, is that the probability of a significant nexus when 
coming to features that have very infrequent flows, low 
magnitudes of flows indicates that the probability downstream 
of an effect is very minimal. This was something that was found 
by the Science Panel in their review.
    Senator Barrasso. Thank you so much.
    General Peabody, is it true that the Corps of Engineers was 
really cut out of the process of drafting the final WOTUS Rule 
and that you asked that the Corps' name be taken off of the 
technical support document and the economic analysis that were 
supposed to be used to justify the Rule?
    General Peabody. Sir, I believe I characterized it in my 
written testimony that the Corps was marginalized, but the time 
period is important because when I arrived at the headquarters 
in late 2013, the process was already underway. The Rule had 
just been proposed and the proposed Rule was promulgated in 
April 2014. Throughout that period, based on the advice I got 
from Corps professionals, the Corps was involved. We certainly 
did not always agree on everything, but I think that is normal. 
People have reasonable disagreements based on their 
perspectives.
    My characterization of the Corps' involvement starting in 
approximately November 2014 is that our involvement was 
limited, distinctly limited, I would say. It was unclear to us 
whether the efforts we made to have our concerns understood 
were in fact understood. We clearly had opportunities to 
comment on various aspects of the Rule. We sought a couple of 
opportunities to talk to Secretary Darcy about the Rule, and 
she heard us out, but our concerns went largely unaddressed.
    Senator Barrasso. In many places the Preamble, the 
technical support document says that the Rule is based on 
agencies' experience and expertise. It is my understanding that 
the Corps, not the EPA, performs the vast majority of the 
determinations of which waters are Federal. If the Corps is 
kind of cut out or marginalized from the process, is it fair 
for me to conclude that the statements that the Rule is based 
on the agency's experience and expertise are not accurate?
    General Peabody. The Corps did not believe at that time, 
and I want to continue to emphasize I do not speak for the 
Corps today. I only speak for the Corps to the extent that I 
understood it at that time. We did not believe that our 
judgment and experience was adequately incorporated into the 
Rule to reflect the experience you reference. Yes, it is also 
true that we had no role, the Corps had no role in analyzing 
the technical support document or doing the analysis, I should 
say, for the technical support document or the economic 
analysis.
    Senator Barrasso. Mr. Tseytlin, you have heard what General 
Peabody said; you heard what Dr. Josselyn has said. Can the 
WOTUS Rule definition, from your role as Solicitor General 
involved in the suits, can the WOTUS Rule definition of 
adjacent water actually hold up in court, then?
    Mr. Tseytlin. No, I do not believe it can. I think the 
clearest way to describe why it cannot is that in the Rapanos 
decision Justice Kennedy specifically said that one of the 
things the Court tried to do there was it tried to base Federal 
jurisdiction on adjacency to tributaries. Justice Kennedy 
specifically said, whatever else you think, you can not base it 
on adjacency to tributaries.
    Remarkably, in the WOTUS Rule, EPA once again attempted to 
base adjacency to tributaries for Federal jurisdiction. There 
are many other problems with the adjacency definition, the five 
football field thing that we talked about before, but that is 
just the most obvious one, that Justice Kennedy clearly said 
you could not do this and then EPA went ahead and did it.
    Senator Barrasso. The 1,500 feet that they used, the 
arbitrary number that has been grasped.
    Mr. Tseytlin. Absolutely. That is exactly right.
    Senator Barrasso. Thanks.
    Senator Carper.
    Senator Carper. My understanding, in 1972, in this room 
they were debating the Clean Water Act. I was over in Southeast 
Asia, not following very closely what was going on, but I had a 
chance to read up on it a little bit since then, and my 
understanding of the intent of the Congress and then-President 
Nixon was to clean up water. They are pretty expansive in their 
scope of doing so.
    We have ended up, over the years, my time as Governor of 
Delaware--I want to especially welcome Collin today and thank 
him for his service to our State and the good work that he is 
doing today. What I heard from folks in Delaware was farmers, 
we have quite a few farmers in the little State, a lot of 
developers, and what I heard pretty consistently was it was 
hard for them to know what they could do or could not do, and 
they just wanted some certainty, some predictability, some 
clarity.
    It is not just a few people, a few developers, a few 
farmers that were saying this, this was like the message from 
all over the Country. When you look at what the Supreme Court 
did, what was the decision, one to four, a plurality? There is 
not a whole lot of guidance there. When I listen to this 
testimony and try to read my briefing notes, this is not an 
easy thing to understand, so I can understand why the Supreme 
Court might have wrestled with the issue of clarity too.
    I want to ask Mr. Kopocis what was your role in all of this 
as this Rule was being developed? Just very briefly what was 
your role?
    Mr. Kopocis. Well, initially when I went over to EPA, I was 
serving as a senior advisor as the President's nominee to be 
the AA for the Office of Water. When the Rule was finalized, I 
was the Deputy Assistant Administrator for the Office of Water, 
effectively running the Office of Water.
    Senator Carper. All right. Now, I might be mistaken, but I 
was under the impression that the EPA did a pretty good job in 
terms of listening. They asked folks who had views on this, 
give us your opinion. My recollection is about a million 
people, businesses, farmers, did just that.
    I understand that there were hundreds of meetings in the 
States across the Country, maybe as many as 400. I was under 
the impression that this was a partnership between EPA and the 
Army Corps of Engineers, and General Peabody's comments today 
are troubling to me. I was under the impression that the Army 
Corps had actually felt that the Rule was not rigorous enough 
based on the Army Corps' analysis of science. That might be 
wrong.
    Could you give us some clarity on that point?
    Mr. Kopocis. Thank you. Yes, we did have countless 
discussions with all the interested groups, as I said in my 
testimony. In particular, with the States, we had special 
meetings with the States during the pendency of the 
consideration of the Rule. We met with ECOS, the environmental 
commissioners, Aqua, the people that actually run the water 
programs, and also the State wetlands managers. We convened 
special panels of their representatives so that they could 
participate in our conversations, and we also formed a special 
subcommittee of the local government advisory committee to go 
around the Country and listen to governmental concerns on the 
Rule.
    We did coordinate extensively with our colleagues of the 
Department of the Army and the Corps of Engineers. Ultimately, 
when it became time to decide what was going to be in the Rule, 
Administrator McCarthy coordinated with Assistant Secretary 
Darcy as to what would be in the Rule. The concerns that 
General Peabody has talked about that were raised in the memos 
we were made aware of very late in the process. Those were 
internal items to the Department of the Army and the Corps of 
Engineers. Those documents were never brought to our attention 
in a time where something could have been changed.
    We looked to the head of the Corps, the Assistant Secretary 
of the Army, I should say the political person responsible for 
policy, to see whether the path that the agencies were 
following was one that they agreed with or not. As I believe 
Jo-Ellen Darcy, Assistant Secretary Darcy testified at this 
Committee that she agreed with the final recommendations and 
the final text of what was in the Rule.
    Obviously, there were differences of opinion within the 
Corps. There were differences of opinion at EPA as well. As you 
said in your opening remarks, nobody has characterized it as a 
perfect rule, and different people, depending on whether they 
could write it by themselves, would have written it 
differently.
    Senator Carper. All right. I hope we have a chance for 
another round. My time has just about expired. Thank you all.
    Collin, I hope I have a chance to ask a question of you. 
Thank you.
    Senator Barrasso. Thank you, Senator Carper.
    Senator Inhofe.
    Senator Inhofe. Thank you, Mr. Chairman.
    First, I have a document here from the American Road and 
Transportation Builders. This Committee is very familiar with 
them as we passed our FAST Act and all of our highway bills, 
and I ask that their comments on this, Mr. Chairman, may be 
made a part of the record.
    Senator Barrasso. Without objection.

    Senator Inhofe. I have to say this about the whole WOTUS 
thing. I go back to Oklahoma when it was first proposed. The 
head of the Farm Bureau of the State of Oklahoma, Tom Buchanan, 
said of all the problems that farmers and ranchers are facing 
in America right now, it really has nothing to do with anything 
that is in the Ag bill; it is overregulation of the EPA. They 
single out the WOTUS Rule as being the greatest concern. We are 
talking about this is nationwide. This is how significant 
people feel about this.
    I remember also, General, back when we were putting this 
thing together, I was chairman of the Committee in 2009 when 
they established this data base called DARTER, which keeps 
track of the permits and it provides the EPA with the ability 
to constantly look over the Corps' shoulders. I said at the 
time that it seems to me that the EPA employees are not trained 
to do jurisdictional determinations, so it does not make sense 
for them to be second-guessing the decisions the Corps has 
made.
    Now, is not this a duplication of effort, in your opinion?
    General Peabody. Senator, I believe the DARTER data base is 
for enforcement actions. It is an EPA data base, and I would 
defer to Mr. Kopocis to talk about that in more detail. 
However, the Corps data base that tracks permitting actions and 
jurisdictional determinations is called ORM2.
    Senator Inhofe. My question is are they really--well, I 
would ask you, Mr.----
    General Peabody. I believe they are two different data 
bases for two different purposes. That is my understanding.
    Senator Inhofe. Okay.
    Any comments, Mr. Josselyn?
    General Peabody. I am sorry, sir?
    Senator Inhofe. Okay, never mind.
    We are interested in removing barriers to building 
infrastructure. Do you have any recommendations, General, for 
us how to streamline the 404 permitting process?
    General Peabody. Sir, the first thing I would say is that 
the process is much more streamlined than most people give it 
credit for thanks to the general permit. There are several 
general permit provisions that enable that. As I indicated, 
about 80 percent of all actions are permitted within 60 days 
from finalizing a policy-compliant application.
    The trouble gets into because the volume is so high, there 
were approximately 79,000 actions in 2016, that it does not 
take a small percentage to result in a large number of actions 
that are not processed efficiently.
    One of the things I think that could be done is that our 
partner agencies have time limits associated with their input 
into these actions. The Corps must coordinate with them to 
ensure that their responsibility, statutory responsibilities 
are addressed adequately. Sometimes on-the-ground, figuring out 
the science to address endangered species and the like takes a 
lot of time.
    I would recommend putting a limit on a period of time for 
an individual permit action, some number of years, short number 
of years, two, three, or four, and then elevating those for 
processing above the level of the----
    Senator Inhofe. From every 5 years to maybe every 10 years?
    General Peabody. Sir, the time period I would defer to the 
Corps and the EPA to make recommendations, and other natural 
resource agencies to make recommendations. There are actions 
that have gone on for over 10 years.
    Senator Inhofe. Yes, I know.
    General Peabody. To me, that is unconscionable.
    Senator Inhofe. There is one out in California.
    Mr. Tseytlin, there is a lot of confusion around the 
staying of the courts on this Rule, and after hearing from the 
testimony about the lack of technical and scientific 
jurisdiction for the Rule, do you think that--well, when the 
stay came on, it did not talk about the merits of the Rule. How 
do you think that would hold up in court?
    Mr. Tseytlin. A necessary prerequisite for the issuance of 
a stay is a finding of likelihood of success on the merits. The 
Sixth Circuit has already found that the States are likely to 
succeed on the merits, proving that the WOTUS Rule is illegal 
under both the Clean Water Act and the EPA. I think a final 
judgment on that would have been finalized if the Rule had----
    Senator Inhofe. That is very clear. Thank you very much.
    Let me just say, Mr. O'Mara, that a comment that was made 
by the Chairman during his line of questioning, and I have a 
great deal of respect for your organization, but it was to have 
more of the landowners' participation in these decisions than 
you normally get out of a bureaucracy. He called to your 
attention the Fish and Wildlife Partnership Program that has 
been tremendously successful, and I assume that you agree with 
that, with that concept and what has made that successful.
    Mr. O'Mara. Absolutely. We have enjoyed working with you 
and your team trying to promote those kinds of collaborative 
vehicles. I think the one thing that we see is that if there is 
a way to reduce pollution at the source, again, not regulating 
activities that are not affected by it, and then combining that 
with some of the collaborative efforts, we could actually 
achieve the water quality goals. Collaboration is always best.
    Senator Inhofe. Thank you very much.
    Senator Barrasso. Senator Duckworth.
    Senator Duckworth. Thank you, Mr. Chairman. I also thank 
the Ranking Member for convening this very important 
conversation.
    My constituents in Illinois are concerned about how WOTUS 
or the Clean Water Rule will affect public health and the 
economy. It is our responsibility and duty as public servants 
to ensure that these objectives are balanced and that one does 
not outweigh or thrive at the expense of the other.
    I am really glad, General Peabody, that you mentioned the 
role of the Corps, especially in dealing with endangered 
species as well. It is why I also urge the Trump Administration 
to make strong science and robust public engagement as the 
foundation of WOTUS as we move forward.
    WOTUS is about water quality, and we will have a water 
quality crisis in Illinois if the Great Lakes Restoration 
Initiative is not prioritized. Today's discussion is 
fundamentally about water quality. WOTUS does play a factor 
with the GLRI. In my State and all across the Midwest, the 
Great Lakes Restoration Initiative is the program that protects 
and safeguards the quality of the largest system of fresh 
surface water in the world, and WOTUS feeds into that.
    Mr. O'Mara, the Trump Administration's skinny budget 
includes a proposal to completely eliminate the Great Lakes 
Restoration Initiative. In your view, how would eliminating 
this Initiative challenge our ability to protect drinking water 
across the Great Lakes region?
    Mr. O'Mara. One of the most successful water quality 
programs in American history has been the Great Lakes 
Restoration Initiative, and I think the Chairman summed it up 
perfectly in his comments at the beginning, that we want to 
foster collaborative activity on the ground. If you cut that 
program, the $400 million that has gone to collaborative 
partnerships on the ground making good habitat projects, water 
quality projects, trying to reduce invasives, you will see a 
deterioration of water quality quickly for the most important 
freshwater supply in our entire Country.
    It is not just that. The proposal to remove the 
headquarters of Region 5 out of Chicago, the idea that the 
place where we just had the Flint water crisis, the place where 
we had the sheen on the Chicago River, the place where we just 
had the challenges in Flint. To not have an important center 
and the resources to take care of the Great Lakes would be 
devastating for the Country's resources.
    Senator Duckworth. Definitely. Can you speak a little bit 
to the economic impact of the Great Lakes Restoration 
Initiative? I mean, we talk about just the quality of the 
water, but we are talking about a region in this Country that 
spans all across the Midwest, goes all the way up into New 
York, and really was the place where so much of our economic 
growth happened in the last century. Let's talk about the 
economic impacts of the Great Lakes Restoration Initiative.
    Mr. O'Mara. Sure. The return on investment of the Great 
Lakes Restoration Initiative is one of the highest of any 
government investment you can make. You are talking about a 
5:1, 10:1 kind of return when you look at the millions of 
people that are employed because of the freshwater in the Great 
Lakes, because of the number of companies that locate in the 
region because of access to that, the tourism industry that 
comes from it.
    The thing that excites me about the Great Lakes, as much as 
any place in the Country, is that you have a bipartisan 
consensus for action, and the fact that when proposals are made 
to reduce funding, Republicans and Democrats come together 
because it is a value. It is not a partisan football. The 
economic impact is as big as any region in the Country, in the 
billions, hundreds of billions of dollars of benefit.
    Senator Duckworth. Thank you. You mentioned the proposed 
closing of EPA Region 5 office, which is the office that 
oversees the entire Midwest region. My constituents across the 
region are deeply concerned, not just those in Illinois, but 
those across the Midwest, about this potential closing of this 
office and how it would undermine EPA's ability to do its job. 
I believe that more than our policy, our people are the 
backbone of the environmental and public health protections; 
scientists like Miguel Del Toral, the EPA Region 5 scientist 
who raised the red flag on the Flint water crisis, all of the 
teams that come out that are the rapid response teams.
    We are about to get into tornado season in the Midwest. 
Actually, we are in it already. With tornado season comes the 
effects of disaster, followup with disasters. The EPA actually 
has people who come out as part of a disaster response team 
that responds when anything like this happens. To not have an 
office in Chicago would literally add days of travel to any 
team that must come in from outside the Midwest region.
    Mr. Kopocis, in your view as a former Acting Assistant 
Administrator for EPA, how can we reasonably expect EPA to 
deliver on its mission of protecting public health if regional 
offices like Region 5 are eliminated or consolidated?
    Mr. Kopocis. EPA's regional offices are a key component of 
accomplishing the mission of the Agency. They are the front 
line that deal with State and local issues. The examples that 
you have raised throughout the Midwest are key. The Chicago 
office, in particular, played a key role in making sure that 
the Great Lakes Initiative was carried out in the most 
effective and responsible way. They were also on the front line 
in dealing with State issues as they come up. Most States do 
not initially contact the EPA headquarters office; they contact 
their regional office, so that role is invaluable.
    Senator Duckworth. Thank you. I am running out of time.
    Mr. Chairman, I would like to submit a letter for the 
record on behalf of the Healing Waters Coalition, which works 
on the Great Lakes issues.
    Senator Barrasso. Without objection.

    Senator Duckworth. Thank you, Mr. Chairman. I yield back.
    Senator Barrasso. Thank you very much for your questions.
    Senator Rounds.
    Senator Rounds. Thank you, Mr. Chairman.
    In my State and others in the Prairie Pothole Region, 
farmers plant in prairie potholes in dry years and plow around 
them in wet years; keeps the land in production. But under the 
WOTUS Rule, those voluntary efforts would be swept aside by 
regulation.
    Dr. Josselyn, in your testimony you State that the 
threshold for establishing a significant nexus under the WOTUS 
Rule is very low. Under the Rule, could any prairie pothole be 
regulated?
    Mr. Josselyn. Yes, sir. The Rule does take prairie potholes 
as a group and says that those areas, not just a single area, 
but all of those prairie potholes, similarly situated is the 
term that they use, and that can combine into then making a 
test that is positive for significant nexus.
    Senator Rounds. Is that result consistent with the 
recommendation of the panel of scientists who reviewed the 
Rule?
    Mr. Josselyn. No, on that particular element, where 
wetlands of a particular characteristic are all combined, was 
not reviewed by the Panel.
    Senator Rounds. General Peabody, the Corps has not 
regulated any geographically isolated wetlands since the 2001 
Supreme Court decision in SWANCC. Is not it true that Corps 
counsel raised concerns about how the WOTUS Rule treats 
isolated waters? In fact, did not the Corps counsel say that 
``this assertion of CWA jurisdiction over millions of acres of 
isolated waters undermines the legal and scientific credibility 
of the Rule''?
    General Peabody. Yes, sir.
    Senator Rounds. Just curious, as chairman of the 
subcommittee on regulatory oversight, we had extensive hearings 
on making certain that the EPA is using the best science 
available in the regulatory process and would take into 
consideration public comments, especially those from scientists 
and State and local officials.
    Gentlemen, do you believe the Agency adequately took 
scientific opinion into consideration and relied on sound 
science when crafting this Rule? Do you believe the Agency 
properly incorporated public, agency, and other scientific 
comments into its review?
    Dr. Josselyn?
    Mr. Josselyn. Senator, the Science Panel was really focus 
on establishing whether systems are connected, but when it came 
to the Rule itself, they looked at arbitrary distances and they 
set those up, and those were not issues that the Panel in fact 
strongly argued against. I believe that the WOTUS Rule as 
finally published was not something that the Panel could have 
supported at that point.
    Senator Rounds. General Peabody, did that come into the 
discussion with regard to the Corps of Engineers and their 
analysis?
    General Peabody. Yes, sir, it did. One of our greatest 
concerns was that notwithstanding incredible effort led by EPA 
to amass all this science, do this report, bring in all of 
these peer review experts and put them to the Science Advisory 
Board review, some of the final judgments in the Corps opinion 
at that time did not reflect what the science said. For 
example, in my personal view, the most stark example of this 
was the 4,000-foot jurisdictional limit that was proposed. I 
definitely understood the desire to provide clarity; I think 
that is a laudable goal. The challenge is that under the 
significant nexus standard, which legal counsel told me and I 
understood to be the common view of the administration to be 
the overriding legal standard that would apply, that you cannot 
have such a clear distinction, a fixed distance that is not 
supported in the underlying science. That was of great concern 
to us that was making the Rule legally vulnerable.
    Senator Rounds. Thank you.
    I want to change subjects just a little bit.
    Mr. O'Mara, I am just curious, are you familiar with the 
Conservation Reserve Program?
    Mr. O'Mara. Absolutely.
    Senator Rounds. I think one of the finest conservation 
products this Country has ever had. Set-aside land, many of it 
some of the least productive farm land, the most at risk with 
drought or flood, and basically you put it back into grassland 
and you set it there for a period of up to 10 years. Farm bill 
coming up. Would you give me your thoughts about the value with 
regard to water resources and what it does for water if the 
Conservation Reserve Program and whether or not it is an 
effective way to actually help in a cooperative effort to make 
for clean water and basically a good sound conservation 
practice?
    Mr. O'Mara. Thank you, Senator. As someone who pheasant 
hunts in your great State, I appreciate it greatly. The water 
benefits are huge. If you are able to protect lands through 
those types of programs and not have additional nutrients 
coming onto the landscape, it is a great way to prevent 
pollution in a very collaborative way. One of the challenges is 
that in the last few farm bills we have seen those programs 
cut, and the amount of dollars going to the Dakotas has gone 
down precipitously. I would much rather have folks getting a 
little bit of incentive to have their land growing ducks and 
pheasants, as opposed to being marginal and kind of hard to 
make commodity prices. We would love to work with your office 
to make that a lot bigger in the next farm bill.
    Senator Rounds. Thank you.
    Thank you, Mr. Chairman.
    Senator Barrasso. Thank you, Senator Rounds.
    Senator Whitehouse.
    Senator Whitehouse. Thank you, Chairman.
    Professor Kopocis, if you look at the Supreme Court 
decisions on point, the three major ones are Riverside Bayview, 
the Northern Cook County decision, and Rapanos. Across all of 
those three decisions has any Supreme Court Justice ever held 
that actual navigability is the proper standard under the Clean 
Water Act?
    Mr. Kopocis. No, sir.
    Senator Whitehouse. Not one.
    Mr. Kopocis. Not one.
    Senator Whitehouse. If an administrative agency were to try 
to follow that standard and then there was a challenge in 
court, how would it predictably turn out?
    Mr. Kopocis. Well, I assume it would not be upheld because 
it would be contrary to the views of the three times the 
Supreme Court has spoken.
    Senator Whitehouse. We can agree that the Rapanos decision 
left much to be desired in terms of clarity. It was a plurality 
situation with no majority decision, and you have to decipher 
the different parts to pull the meaning out of it. It is my 
understanding that every single circuit court that has looked 
at this has decided that the Kennedy rule, the significant 
nexus rule, is the operative rule to extract from the Rapanos 
decision. Is that your view of the law as well?
    Mr. Kopocis. Every circuit court that has opined has said 
that the Agency's use of the Kennedy test was appropriate.
    Senator Whitehouse. Okay. Significant nexus is obviously 
something different than actual navigability. If we are to 
hypothesize a seasonal stream, and you know every year in the 
rainy season it is going to run down into the navigable water, 
is it not necessary and logical and should not the people who 
live and recreate in the navigable water be able to count on 
the Federal Government saying, no, you can not dump pollutants 
in the dry season into that streambed, when we all know 
perfectly well that when the rains come it is all going to be 
washed down into the navigable waters?
    Mr. Kopocis. Yes. It is simply physically impossible and 
technically impossible to protect the water quality of the 
navigable waters without protecting at least some of the 
tributaries that feed into it.
    Senator Whitehouse. From a practical point of view, Mr. 
O'Mara, that is what the hunters and the fishers and the people 
who live by and swim and boat in our lakes and other freshwater 
resources expect, is it not?
    Mr. O'Mara. Absolutely. If you look at the millions of jobs 
and the billions of dollars of economic activity, if there is 
no water quality, there is no fish. If there is not healthy 
wetlands, there is no ducks. I mean, it comes down to the 
basics.
    Senator Whitehouse. If the Federal Government sat by and 
let polluters dump pollutants into a streambed when everybody 
would know perfectly well that when the rains came that would 
go down into the navigable and recreational waters and ruin the 
public's enjoyment of that, how would your millions of members 
feel about how responsible the Federal Government had been in 
letting that happen?
    Mr. O'Mara. We have done polling on it among sportsmen and 
women across the Country, and more than 80 percent of sportsmen 
and women support protecting those streams for that reason, 
because they do not want to have the places they love and the 
places they depend on economically being destroyed by the 
pollution.
    Senator Whitehouse. Foreseeing rain is not too challenging 
a project to expect the Federal Government to be able to 
achieve, correct?
    Mr. O'Mara. More of it to come.
    Senator Whitehouse. Yes, more of it to come.
    Now, we also have something in common from your previous 
life. You are a Delawarean, if that is the right word, and I am 
a Rhode Islander. Both of our States are coastal States and 
both of our States are downstream States. If the EPA is not 
actively defending upstream conditions outside of our States, 
who looks out for us in our small downstream States?
    Mr. O'Mara. The challenge we have, as Senator Carper often 
says, we are kind of the tailpipe on the air emission side and 
kind of the sewer on the water side. I mean, the State of 
Delaware could eliminate every single source of pollution in 
its States that is winding up in its waterways and still not 
have a healthy estuary for the Delaware or for its part of the 
Chesapeake. Unless you are having like regional compacts and 
basically voluntary agreements with adjacent States, there is 
no way to make sure that we actually have healthy waterways.
    Senator Whitehouse. Professor Kopocis, back to lawyering 
again. In my hypothesis that a foreseeable rain is going to 
wash a known pollutant into navigable waters, do you think that 
a WOTUS Rule that failed to protect against that foreseeable 
event would pass scrutiny under the significant nexus test?
    Mr. Kopocis. No, sir, I do not.
    Senator Whitehouse. Would not make any sense, would it?
    Mr. Kopocis. No, sir. In fact, those kinds of concepts were 
specifically rejected by Justice Kennedy, saying that they made 
little sense and were unpersuasive.
    Senator Whitehouse. To some extent, a lot of the 
complaining that has been done about the EPA rule here is 
actually complaining about the significant nexus test, but that 
is the law, correct?
    Mr. Kopocis. Yes, sir, it is.
    Senator Whitehouse. Okay. My time is up.
    Thank you, Chairman.
    Senator Barrasso. Thank you very much, Senator Whitehouse.
    Senator Ernst.
    Senator Ernst. Thank you, Mr. Chairman, and thank you very 
much, everyone, for this great discussion today.
    I do want to point out we still have the Clean Water Act, 
and I hope that within that Act we are not allowed to dump 
pollutants willy nilly. I think what we are talking about right 
now is the expanded definition of waters of the U.S., not the 
original Clean Water Act. I hope we are protecting our citizens 
without that expanded definition. I think that is what we are 
dealing with today.
    Mr. Josselyn, as part of the propaganda campaign that the 
Government Accountability Office found to be illegal, the Obama 
EPA tried to get people to believe that unless they regulate 
ephemeral water, which, by definition, is a stream that flows 
only briefly during and following a period of rainfall, so 
essentially rainwater runoff, that the drinking water of 117 
million people would be at risk. Mr. Kopocis and Mr. O'Mara 
repeat this claim in their testimony.
    EPA put up a map on their website to support this claim, 
and this is this chart right here. However, if you read EPA's 
summary of the analysis, which is, of course, buried on a 
different web page than this map, you find out that EPA based 
this claim on a study of streams that are visible at medium 
resolution, which is what you see behind me. At this scale, you 
are only going to see major streams.
    Does a study of those major streams at that scale have 
anything to do with ephemeral streams?
    Mr. Josselyn. Thank you, Senator. In response to your 
question, the map scale is about 100,000 scale. You know, when 
I was a Boy Scout, I used 7.5 minute quadrangle maps, and they 
have a scale of 24,000. The scale is quite large, so that is a 
problem with that.
    Also, the data base that they used I am very familiar, the 
NHD data base plus. That data base really only maps perennial 
and intermittent streams. In fact, the definition that they use 
is any stream that flows more than after immediate rainfall. 
Ephemeral streams are defined as streams which flow only after 
rainfall. The NHD data base that they used ignores those kinds 
of features.
    The study really, although provides useful information, it 
is not accurate in its conclusion.
    Senator Ernst. Yes. Thank you very much.
    Mr. Tseytlin, as a legal matter, is it correct to say that 
EPA has to regulate ephemeral streams to protect drinking 
water?
    Mr. Tseytlin. Absolutely not. Also with regard to the 
drinking water point in particular, of course, Federal law 
outside the Clean Water Act, the Federal Safe Drinking Water 
Act is the primary Federal protection. I believe that the focus 
on drinking water is part of that GAO found illegal propaganda 
campaign, which was meant to drum up, illegally again, support 
for the WOTUS Rule.
    Senator Ernst. Yes. Thank you.
    Mr. Tseytlin, the Obama EPA claimed that farmers did not 
need to worry about the WOTUS Rule because it exempted 
``ordinary farming activities from permits.'' Are you familiar 
with the Duarte case in California?
    Mr. Tseytlin. I am.
    Senator Ernst. In that case, the Corps and the Department 
of Justice claimed that a farmer needed a permit to plow his 
own land because the tops, again, right here, the tops of the 
plowed furrows dry out in the sun and constitute, and no jokes, 
folks, mini mountain ranges. Mini mountain ranges. Plowing does 
not qualify as an ordinary farming activity. My farmers would 
beg to differ.
    Here is a picture of those mountain ranges from the report 
written by DOJ's expert witness. I guess under this definition 
Iowa is one of the most mountainous States in the United 
States.
    What is left of the ordinary farming exemptions if you can 
not even plow your own soil?
    Mr. Tseytlin. You are exactly right, Senator, and that is 
exactly the danger of expanding the jurisdictional reach of the 
Clean Water Act, which is what the WOTUS Rule tries to do, 
which is why the American Farm Bureau and the Wisconsin Farm 
Bureau and farmers all over the Country oppose very strongly 
the WOTUS Rule.
    Senator Ernst. Yes. By these definitions, the entire 
expanded definition, 97 percent of the State of Iowa is 
regulated by that expanded definition and considered waters of 
the U.S.
    Thank you very much.
    Thank you, Mr. Chair.
    Senator Fischer. [Presiding.] Thank you, Senator Ernst.
    Senator Harris.
    Senator Harris. Thank you.
    I have three committee meetings all scheduled at the same 
time this morning.
    Mr. Kopocis, thank you for being here. The Clean Water Act 
is very important to me, and the Act ensures, of course, that 
there will be environmental justice for all communities. It 
ensures that all Americans have access to clean and safe 
drinking water. However, the Clean Water Act has lacked clarity 
in defining jurisdiction for Federal agencies to protect the 
sources of drinking water.
    During your tenure at the EPA, I understand that you also 
worked closely on the Clean Water Rule. Do you believe that the 
Clean Water Rule was promulgated to provide clarity to the 
Clean Water Act?
    Mr. Kopocis. The primary purpose of issuing that rule was 
to provide greater clarity, certainty, and predictability that 
was lacking in the post-Rapanos world.
    Senator Harris. Thank you.
    The Obama administration finalized the Clean Water Rule 
after extensive analysis of legal statute, after multiple 
agencies' technical expertise, millions of comments during the 
public comment period, and the best available peer-reviewed 
science. This past Saturday Americans from all over the Country 
marched in support of science and its value in creating sound 
policy like the Clean Water Rule.
    Could you please explain to me the extent to which the EPA, 
during your tenure, used science-driven research into the final 
determination of the Clean Water Rule? In the event that this 
Administration decides to reevaluate the Clean Water Rule, what 
must the EPA do to guaranty that any future version of the 
Clean Water Rule is held to the same standard?
    Mr. Kopocis. The agencies looked at what the Supreme Court 
has said and recognized that they needed to do a better 
analysis of the science of how waters were interconnected with 
each other and the impacts of upstream waters on downstream 
waters. The Agency challenged its Office of Research and 
Development to do an extensive research on the literature as to 
what existed to inform the Agency. ORD looked at about 1,200 
different peer-reviewed documents in coming up with its 
synthesis of the Science Report.
    Unfortunately, science does not address issues such as 
significant nexus. Science talks about how waters are 
interrelated to each other. As Mr. Josselyn said earlier, one 
of the recommendations of the SAB is that the Agency needed to 
recognize that waters are connected on a continuum, that there 
is not a single point that you can place on that continuum if 
you are looking at it from a purely science background.
    However, the agencies use science to inform its policy 
decisions. Science was not going to decide the issue 
necessarily for the agency because the Agency had to operate 
within the confines of a statute and the guidance from the 
Supreme Court. Science was the informative information that the 
Agency used to come up with Rule going forward.
    Senator Harris. Do you have any instruction for the EPA, or 
guidance or good advice, if they should reevaluate the Clean 
Water Rule?
    Mr. Kopocis. Well, my first recommendation would be to do 
not do it, but they have announced that they are going to.
    Senator Harris. They seem intent on doing it.
    Mr. Kopocis. Absent that, then I would suggest that they 
take a look at the science. If there is new and better science, 
then I would encourage the Agency to look at it. If what the 
Agency chooses to do instead, as is stated in the Executive 
Order, is rely on Justice Scalia's plurality opinion, that will 
greatly narrow the scope of the Clean Water Act over what it 
is, and that will be a narrowing that is contrary to the 
science that was developed by us in the prior Administration.
    Senator Harris. Thank you.
    Could you describe the process of public engagement that 
was followed in proposing and issuing the Clean Water Rule, and 
what feedback the EPA received? Could you share with the 
Committee your understanding of what sort of process the 
current Administration has committed to it in its efforts to 
replace the Rule? Emphasis here on the public process.
    Mr. Kopocis. What we did, we had extensive meetings with 
all interested parties, State and local governments, etcetera, 
before the Rule was drafted and put out for public comment. 
During the public comment period, which lasted over 200 days, 
we met with interested parties again. We had over 400 public 
meetings or phone calls, teleconferences. I personally, in my 
capacity, attended about 70 of those. We visited farms; we went 
out in the field to talk to people. We evaluated about, I 
believe the final number was close to 1.3 million comments on 
the Rule. We responded to those comments in a several hundred 
page long response to comments document that was prepared 
jointly by us and the Army Corps. We took all of that 
information to develop what is the final Rule.
    I cannot speak to the plans of the current Administration; 
however, I have not yet seen signs that there is that same 
level of public involvement because those meetings have not yet 
occurred.
    Senator Harris. Thank you.
    Thank you all.
    Senator Fischer. Thank you, Senator Harris.
    Dr. Josselyn, today, General Peabody has testified that the 
Corps staff were concerned that the bright line geographic 
tests in the WOTUS Rule could include water that should not be 
regulated and could exclude water that should be regulated. I 
want to focus on whether the WOTUS Rule would actually exclude 
any water.
    You note in your testimony that the EPA found ``the vast 
majority of the Nation's water features were located within 
4,000 feet of a covered tributary, traditional navigable water, 
interstate water, or territorial sea.'' That finding is 
supported by the analysis performed by Geosyntec for the 
American Farm Bureau Federation in a sampling of States. 
Specifically, Geosyntec analysis shows that 100 percent of the 
land area of Virginia is located within 4,000 feet of something 
that meets the WOTUS Rule definition of tributary. The same is 
true for 99.7 percent of Missouri, 99 percent of Montana, 99 
percent of Pennsylvania, as Senator Ernst said, 97 percent of 
Iowa, 95 percent of Oklahoma, 95 percent of California, and 92 
percent of Wisconsin.
    You are from California, so I would like to use that as an 
example. Based on the definition of significant nexus, which we 
have tossed around here today, but based on that definition in 
the WOTUS Rule, and assuming that the Geosyntec analysis is 
correct, would you agree that any water located in 95 percent 
of the land in California could be regulated under that Rule?
    Mr. Josselyn. Yes, Senator. Thank you. We also did an 
analysis in the San Francisco Bay area, and we found that all 
the land in the San Francisco Bay area would be covered under 
that 4,000-foot standard, except for the core urban areas of 
San Francisco, Oakland, and San Jose. It is quite true, and the 
significant nexus test itself has a very low threshold in terms 
of what would be required to have a significant nexus, so most 
of those areas would be regulated.
    Senator Cardin. Could I ask my colleague to just yield for 
one moment? I am not going to be able to ask questions because 
of time restrictions. I would just ask consent that the 
American River statement be made part of the record, and I will 
ask my questions for the record.
    Senator Fischer. Without objection.
    [The referenced information follows:]
    [GRAPHICS NOT AVAILABLE IN TIFF FORMAT]
    
    Senator Fischer. What about States that are not included in 
that analysis? Nebraska was not included. Can you conclude that 
over 90 percent of the State would be regulated under that 
final WOTUS Rule?
    Mr. Josselyn. In fact, in the WOTUS Rule, in the Preamble, 
they talk about the fact that the 4,000-foot limit was meant to 
include most all of the wetlands in any State.
    Senator Fischer. Mr. Tseytlin, do you believe that the 
Clean Water Act regulates all water in a State?
    Mr. Tseytlin. That is not within the coverage of the Act. 
The Act applies to navigable waters and, under Justice 
Kennedy's approach, waters that have a significant nexus to 
those navigable waters.
    Senator Fischer. Dr. Josselyn, in November 2015, 4 months 
after the final Rule was published, EPA added a review of 199 
jurisdictional determinations to the WOTUS Rule docket, and in 
this review EPA found that only 2 positive jurisdictional 
determinations would change to negative, affecting 
approximately 1 acre of wetlands. EPA used this analysis to 
show that the Rule would not cutoff jurisdiction.
    However, the EPA's analysis also shows how the Rule expands 
Federal control over land, and of the 199 jurisdictional 
determinations EPA evaluated, 57 were negative. In 47 of those 
57 negative jurisdictional determinations, the Corps concluded 
that Federal jurisdiction did not exist because there was no 
surface connection to navigable water.
    Based on the definition of significant nexus under the 
WOTUS Rule, the new one, do you agree that most of the 47 
negative jurisdictional determinations evaluated by the EPA 
could become positive jurisdictional determinations under the 
final Rule?
    Mr. Josselyn. Senator, I did look at that study and the 
WOTUS Rule also includes shallow subsurface groundwater 
connections as a potential, so that could make some of those 
features that had isolated surface water to be connected.
    Second, the WOTUS Rule expands the definitions of 
tributaries, so there could be far more tributaries mapped in 
proximity to these features and that could also expand the 
jurisdiction for those areas.
    Senator Fischer. Thank you.
    Mr. Tseytlin, the Department of Justice used the November 
2015 document to defend the Rule in the brief that they filed 
on January 13th of this year. Would the EPA's post hoc 
rationalization of their 4,000-foot threshold be credible to a 
court? What is your opinion on that?
    Mr. Tseytlin. It would not be legally permissible to be 
stated in court under the Supreme Court's Chenery case. A rule 
can only be upheld on the basis of the record that was before 
the Agency wanting to issue the final Rule.
    Senator Fischer. Okay. Thank you very much.
    Mr. Chairman, I hand you back your gavel. Thank you.
    Senator Barrasso. [Presiding.] Thank you, Senator Fischer. 
Appreciate your line of questioning and taking the chair.
    Mr. Tseytlin, Mr. Kopocis just testified that the EPA 
relied on the Corps' political appointee instead of the Corps' 
experts. If the Rule is not based on agency experts, is it 
arbitrary and capricious?
    Mr. Tseytlin. Well, the arbitrary and capricious nature of 
Rule reviews the entire record, and as I believe the testimony 
of some of my fellow colleagues here says, the record does not 
support the underpinnings of the Rule. Furthermore, as 
Professor Kopocis conceded, the science that EPA relied upon 
cannot be the basis for significant nexus finding because that 
was not what the Science Report was doing. With regard to the 
significant nexus finding, that is a legal conclusion. As the 
Sixth Circuit preliminarily concluded and as the District of 
North Dakota preliminarily concluded, the legal basis for the 
Rule was lacking.
    Senator Barrasso. Mr. Kopocis also testified that Justice 
Kennedy's opinion controls the definition of waters of the 
United States. Is the WOTUS Rule consistent, do you believe, 
with Justice Kennedy's opinion?
    Mr. Tseytlin. It is not consistent. I gave an example 
earlier, the most obvious example, which is that Justice 
Kennedy said in no uncertain terms in Rapanos, Corps, you can 
not base Federal jurisdiction on adjacency to tributaries. They 
did the exact same thing here and they doubled-down on it by 
adding the 100-year floodplain concept, which, to be clear, the 
connection is based on a connection that happens on a once in a 
century rainstorm.
    Senator Barrasso. Mr. Kopocis, I see you wanting to join 
in.
    Mr. Kopocis. Yes. Yes, if I could. I wanted to draw the 
distinction, though, on Justice Kennedy's opinion. Justice 
Kennedy said that in the situation that was presented to him, 
that the Corps had asserted jurisdiction based solely on the 
grounds of adjacency to a tributary. He said that that was not 
the basis on which they should have made their decision; 
instead, they should have made their decision based on the 
significant nexus presence or lack of presence, and that he 
suggested that that was the correct test.
    I do not look at Justice Kennedy's opinion in the same way 
in saying that he said that you could not look at adjacency to 
tributaries. What he said was you should not have solely relied 
on that and you looked at the wrong test.
    Senator Barrasso. Mr. Tseytlin, anything else that you 
would like to add?
    Mr. Tseytlin. Right. This is what Justice Kennedy said. He 
said, ``Drains, ditches, streams remote from entering navigable 
in fact waters and carrying only minor volumes toward it are 
not a sufficient basis, especially when it is done on 
adjacency.''
    The Rule, on its face, covers drains, ditches, remote 
streams remote from entering navigable water and carrying only 
minor volumes. It could not be clearer.
    Senator Barrasso. General Peabody, your written testimony 
says the Corps does not believe that the Rule and Preamble, as 
ultimately finalized, ``were viable from a factual, scientific, 
and legal basis.'' Then you went on to say it would be 
incredibly difficult for Corps leaders, regulatory and legal 
staff, to advance and defend this Rule.
    You have also testified that statements and 
characterizations of the WOTUS Rule as a joint product of EPA 
and the Corps are flat out wrong. Given these facts, do you 
agree that the WOTUS Rule should be withdrawn?
    General Peabody. Senator, I believe a lot has transpired 
since I retired almost 2 years ago. It is now in litigation and 
I think the facts of the litigation would have to be considered 
to make that policy judgment. It was my position that the Corps 
is responsible for executing policy decisions before they are 
made. It is also the responsibility of Corps leaders to ensure 
that the Corps' professional judgment is clearly understood, 
and that was my primary motivator in writing those memoranda.
    Senator Barrasso. It is not just the final Rule, to me, 
that needs to be withdrawn, because on January 13th of this 
year the Department of Justice filed a brief that makes the 
same statements about the Corps' involvement in the Rule, and I 
believe that brief also needs to be withdrawn.
    General Peabody. Sir, to be clear, it was the Corps' 
opinion, and I believe this is unanimous of all the people I 
consulted with, that the Rule needed to be changed in order to 
be scientifically supportable and legally defensible.
    Senator Barrasso. The Rule is going to regulate any water 
that meets the new definition of adjacent water. In a stark 
departure from current practice, this means that water or 
wetlands do not need to be connected to any other water to be 
regulated, just needs to be within a certain distance.
    General Peabody, on April 2015, a memo from the Army Corps 
counsel to you says, ``Federal courts may find that common 
sense dictates that a water body located 1,500 feet from a 
stream''--and I think, Mr. Tseytlin, you referred to this as 
the five football fields that you have been referring to in 
your testimony as well as your answering of questions--``1,500 
feet from a stream is too far away from that stream to be 
defined as neighboring and, thus, adjacent to that stream.'' It 
went on to say that ``non-science based tests based on 
distances from other water makes the draft final Rule legally 
vulnerable.''
    Are you aware of any analysis by anyone that says that any 
water or wetland located five football fields away from any 
other regulated water has a significant nexus to that navigable 
water?
    General Peabody. Is this for me, sir?
    Senator Barrasso. Yes, sir.
    General Peabody. Sir, the only analysis I am aware of, and 
I would defer to Dr. Josselyn, but in the Connectivity Report I 
believe it states that there is scientific evidence that 300 
feet can establish connectivity for a variety of scientific 
reasons. That is the only analysis I am aware of that addresses 
a specified distance.
    Senator Barrasso. Three hundred feet, but not five times 
that.
    General Peabody. Sir, I was not aware at that time, and I 
am not aware now, of any basis for a 1,500-foot or 4,000-foot 
or other distance beyond the 300 feet I just discussed.
    Senator Barrasso. Thank you.
    Senator Carper.
    Senator Carper. Thanks so much.
    I am going to ask a question of Collin O'Mara. Collin 
O'Mara did a great job as our Secretary of the Department of 
Natural Resources and Environmental Control, a role previously 
filled by the fellow sitting right behind me, Christophe Tolou, 
so we are sort of getting the band back together here this 
morning.
    One of the things that Collin and Christophe talk a lot 
about are secrets to being married for a long time. When Collin 
got married, he sent a handwritten note with a gift to he and 
his wife last year, I think, and I think I recommended him to 
keep in mind the three Cs: communicate, compromise, 
collaborate. The secret to a long marriage. It is also the 
secret to a vibrant democracy.
    I listened to the testimony here today, and we are talking, 
but I do not know that we are in a collaborative mood here. I 
do not feel a sense of compromise. This is kind of like we are 
talking past each other.
    Collin, with that in mind, one of the things we tried to do 
in Delaware with our friends from other States, things we try 
to do in Delaware is like embrace the three Cs. We kind of call 
it the Delaware way and it is part of the secret for our 
success.
    Am I just misreading this or is there something to what I 
am saying?
    Mr. O'Mara. This is incredibly complicated. There is a 
reason why the Supreme Court had five different opinions in a 
single decision. There is a reason why it has taken years to 
get to this point.
    The science, I think, is fairly clear, and I think the 
clarity that is offered through the Rule does offer a path 
forward. I am not going to say there are not enforcement 
mistakes that are made. I am not going to defend every single 
action of the agencies. I do think if we could get to a 
conversation about the focus of the scope of where the 
pollutants are coming from and how we can actually have healthy 
water in this world and then complement that work with 
investments and things like the State Revolving Funds and 
collaborative programs where you could actually achieve healthy 
water. I think at the end of the day it is going to take good 
folks being around the table.
    I do think that the EPA process was exhaustive. I think 
they did a very good job going out. It is something that 
affects a lot of people, though.
    Senator Carper. They came to Delaware. We actually had a 
meeting on a farm and a bunch of farmers around us. We had the 
leadership of the Delaware Farm Bureau and I thought it was 
pretty amazing. My guess is it is probably not the only farm 
they went to among those 400 stakeholders they met with.
    Thank you.
    Let me ask a question of Mr. Kopocis. I think I may have 
been out of the room when Senator Ernst asked this question, 
but I think she may have cited a number of examples of farming 
activities that she believes cannot be conducted under the 
Clean Water Rule that we are discussing today. I would just ask 
is plowing allowed under the Rule?
    Mr. Kopocis. Yes. Yes. The statute specifically provides a 
permit exemption for normal farming practices, including 
plowing.
    Senator Carper. All right, thank you. Is the definition of 
waters of the U.S. more expansive than it was prior to the 2001 
and 2006 court decisions? Is it more expansive or less?
    Mr. Kopocis. The new Rule is less expansive than the prior 
Rule.
    Senator Carper. Why do you suppose we hear so much from 
around the Country that would suggest otherwise?
    Mr. Kopocis. Well, Senator, it is difficult to say. I do 
think that some of that is based on while the prior Rule itself 
was more expansive in a post-SWANCC and post-Rapanos world, the 
agencies were perhaps administering it in a more narrow way. 
The Bush era guidance in the post-Rapanos world allowed for the 
assertion of jurisdiction over isolated waters, but created an 
incredibly cumbersome way to do it, and that is why earlier the 
Committee heard that the agency had not asserted jurisdiction 
over those waters. Those waters were still able to be analyzed 
for jurisdiction; they simply were not in fact being done.
    Senator Carper. All right. A question, if I could, Mr. 
Kopocis, for you and General Peabody. Would a new rule based on 
Justice Scalia's opinion be more expansive or more restrictive 
than the Clean Water Rule?
    Mr. Kopocis. Well, a rule based solely on Justice Scalia's 
opinion would be considerably narrower than the Clean Water 
Rule, and in our many conversations with the Department of Army 
and the Corps, what we heard repeatedly was a concern that in 
fact the limitations that were being written into the Clean 
Water Rule made the Rule too restrictive. It seems to me that a 
rule written solely on the Scalia opinion would be even more 
restrictive than what is currently out.
    Senator Carper. Okay.
    General Peabody, would you take a shot at the same 
question? I will just restate the question. Would a new rule 
based on Justice Scalia's opinion be more expansive or more 
restrictive than the Clean Water Rule?
    General Peabody. Senator, I believe that the Corps would 
need to analyze that based on all the jurisdictional 
determinations that it has made; however, I do think that it is 
probably fair to draw that supposition. I would want to see the 
evidence before I was sure of that one way or the other.
    Senator Carper. All right.
    General Peabody. I do not have any evidence one way or the 
other.
    Senator Carper. Okay.
    My time has expired again. I have some questions I am going 
to submit for the record, and would appreciate the time to 
respond. Did you want to say something, Ken?
    Mr. Kopocis. Well, I just wanted to make sure that the 
Committee understood that EPA and the Army and Corps worked 
very closely together. Obviously, there were some differences 
of opinion as the Rule was coming to an end. We still, on 
behalf of my time at EPA, we still worked very hard to try to 
maintain a collaborative effort. I do not want the Committee to 
go away without remembering that since 1979, when Attorney 
General Civiletti issued his opinion, that the final, the final 
responsibility for determining what is a water of the United 
States, the jurisdiction of the Clean Water Act, belongs to 
EPA.
    Senator Carper. All right, thanks.
    General Peabody. Senator, if I could add to that. I also 
want to clarify that Mr. Kopocis and I worked many issues 
during the time that we served in government, and we did not 
always agree, but we always worked hard to try to find 
solutions to those issues. The limited nature of the engagement 
of the Corps in this particular instance was atypical of my 
experience working in government.
    Senator Carper. Well, I appreciate that clarification.
    Thank you so much.
    Senator Barrasso. Well, I want to thank all the witnesses 
for being here today. If there are no more questions, members 
are also allowed, as Senator Carper just mentioned, will be 
submitting followup questions for the record. The hearing 
record will be open for 2 weeks.
    I want to thank all of you for being here.
    The hearing is adjourned.
    [Whereupon, at 12:05 p.m. the committee was adjourned.]
  

                                  [all]
