Moving Forward on Gulf Hypoxia
                        Moving   Forward
                             More than thirty years after the passage
                             of the Clean Water Act, a large area
                         of low oxygen or hypoxia, absent of most
                         marine life and threatening to inexorably
                         change the biology of the region, continues
                         to form in the Gulf of Mexico during periods
                         in the summer off the coasts of Louisiana
                         and Texas. The hypoxia is primarily caused
                         by excess nutrients—originating from the
                         great productivity of Middle American cities,
                         farms, and industries—which cause extensive
                         growths of algae that deplete the oxygen in
                         the water when  they die, sink to the bottom,
                         and decompose. The condition is exacerbated
                         by the stratification of the water column—
                         the result of warmer, low salinity surface
                         waters that isolate the organic-rich bottom
                         waters from the  surface and prevent oxygen
                         exchange with the atmosphere—which
                         occurs where the Mississippi River meets the
                         Gulf of Mexico.

                         The watershed of the Mississippi River drains
                         41 percent of the contiguous United States
and includes waters from several major river
systems, including the Missouri/Platte River
Basin, the Ohio/Tennessee River Basin, and the
Arkansas/Red/White River Basin. The Mississippi
River Basin includes two functionally distinct
zones, each with its own potential to contribute
to the reduction of Gulf hypoxia. These zones
include the huge Mississippi watershed with
its tributary network, and at the lower end of
the river system, the deltaic zone that formerly
dispersed river water naturally throughout
Southeast Louisiana via a distributary (deltaic)
network. While the tributaries of the Mississippi
River are the sources of nutrient loading to
the river trunk, the distributaries within the
Mississippi Delta are critical to the final dispersal
of nutrients and  sediments into the Gulf of
Mexico and the salinity of the estuaries and
coastal waters.

The distributary zone includes the entire area
influenced by river flow south of the Old River
Control Structures, where the Atchafalaya River
diverges from the lower Mississippi River and

    the Red River merges with the Atchafalaya
    (Figure 1). During the past two centuries
    the hydrology of the distributary zone was
    totally modified by the construction of flood
    levees and closing of key distributaries for
    flood control and navigation enhancement
    programs. These structures isolated the river
    from its delta, causing an ongoing catastrophic
    collapse in the deltaic landscape, primarily
    wetlands. The hydrologic changes that have
    caused such damage to South Louisiana
    also exacerbate Gulf hypoxia by jetting most
    nutrient-rich river water and sediments directly
    into the Gulf of Mexico, bypassing the deltaic
    wetlands that require the nutrients and
    sediments.

    States and Tribes within the entire Mississippi/
    Atchafalaya River Basin and Federal agencies
    are working  together to take action to reduce
    the size of the hypoxic zone, while protecting
    and restoring the human and natural resources
    of the Mississippi River Basin. In January 2001,

Moving Forward on Gulf Hypoxia
                                 Nutrient Task Force issued the Action Plan for
                                 Reducing, Mitigating, and Controlling Hypoxia
                                 in the Northern Gulf of Mexico. The plan was
                                 submitted in accordance with the Harmful
                                 Algal Bloom and Hypoxia Research Control
                                 Act of 1998. The plan stimulated a great deal
                                 of collaboration in understanding science and
                                 planning; however, much work remains to be
                                 done to implement it.

                                 The Task Force has  updated the initial plan
                                 through a multiple-step reassessment. This
                                 2008 Action Plan reflects the Task Force's efforts
                                 to track progress, update the science, and
                                 adapt actions to improve the effectiveness of
                                 the efforts throughout the Basin. Building on
                                 the 2007 Action Plan, this  plan lays out specific
                                 steps that need to be accomplished to reach
                                 the goals. It  also reiterates the long term goals
                                 and  continues the Task Force's  commitment
                                 to an adaptive management approach
                                 to reduce the size and impact of the Gulf
                                 hypoxic zone and improve water quality in the
                                 Basin. This adaptive management approach
                                 involves continual feedback between the
                                 interpretation of new information and
                                 improved management actions and is the key
                                 to targeting actions within watersheds where
                                 they will be  most effective.
Six major policy themes provided direction
for the reassessment. These themes address
needed improvements to the 2007 Action Plan
within the adaptive management framework
and include:

1. Acknowledge the social, political and
economic changes and links to emerging
issues and policies. The vast drainage basin
of the Mississippi/Atchafalaya River Basin and
the adaptive management framework of the
Action Plan require that the Task Force analyze
the broad landscape and policy changes that
impact the hypoxic zone and water quality in
the Basin. These trends may include wetland
trends in both the upper and lower basin,
channelization of the Mississippi River and
how it affects the hydrology of the Mississippi
and Atchafalaya deltas, and the role of energy
and agriculture markets on  land use in the
Mississippi/Atchafalaya River Basin.

2. Ensure greater specificity and
accountability and tie to funding
strategies. The Task Force must identify the
appropriate actions and engage State, Tribal,
and Federal agencies and stakeholders to
identify the appropriate funding strategies that
will be the most effective in ensuring  timely
                                                       Mississippi River/Gulf of Mexico Watershed Nutrient Task Force • Gulf Hypoxia Action Plan 2008

implementation to achieve measurable and
effective results.

3. Track program and environmental
progress. The Task Force needs to improve
communication, better understand the
results of its efforts, and improve tracking and
integration of results into improved design
and targeting of adaptive strategies in future
reassessments.

4. Adapt to new scientific findings.
The Task Force has been active in soliciting
and evaluating the latest scientific findings
through a  series of symposia on relevant topics
and advice from a panel of experts under
the United States Environmental  Protection
Agency's (EPA) Science Advisory  Board.
5. Maximize opportunities for stakeholder
involvement. Given the cooperative and
voluntary nature of the Action Plan, the
Task Force must engage a wide range of
stakeholders and facilitate broad acceptance of
the plan in order to maximize opportunities for
stakeholders to pursue the identified actions.

6. Reexamine roles and responsibilities
of Task Force partners. A reassessment
of the roles and  responsibilities assigned to
the Federal agencies, the States, Tribes, and
the Sub-Basin Committees in achieving the
goals of the Action Plan will improve future
implementation and action.

The Task Force has revised and reaffirmed the three goals that conform to these principles and will
provide the overall measure of the results of the plan:

                                                                                                    i
   •-"                    Subject to the availability of additional resources, we strive to reduce or     [
        make significant progress toward reducing the five-year running average areal extent of    J
        the Gulf of Mexico hypoxiczone to less than 5,000 square kilometers by the year 2015       '
        through implementation of specific, practical, and  cost-effective voluntary actions by all    i

       sediment reduction actions to protect public health and aquatic life as well as reduce
       negative impacts of water pollution on the Gulf of Mexico.
                               To improve the communities and economic conditions across the   J

     The Task Force understands the difficulty of meeting the 2015 goal so is therefore including a revision that takes into account the uncertainty   J
     of the task but attempts to maintain momentum and progress achieved to date. As such, at this time, the Task Force accepts the advice       i
     of EPA's Science Advisory Board on this topic.. .The 5,000 krrf target remains a reasonable endpoint for continued use in an adaptive         J
     management context; however, it may no longer be possible to achieve this goal by 2015... it is even more important to proceed in a directionally   i
     correct fashion to manage factors affecting hypoxia than to wait for greater precision in setting the goal for the size of the zone. Much can be      J

           Moving Forward on Gulf Hypoxia
                                            Much planning and implementation is under
                                            way at the local level, as well as through
                                            federal and state programs, to address
                                            scientific and management concerns and
                                            to put the conservation practices and
                                            management practices and technologies in
                                            place to reduce nutrient loads. Progress is
                                            being made; however, ongoing programs,
                                            rather than new initiatives, are responsible for
                                            most of the  progress. Furthermore, progress is
                                            often the result of collateral benefits resulting
                                            from actions States and Federal agencies have
                                            taken independently of the hypoxia Action

                                            science, restore local water quality, or improve
                                            the efficiency of industrial and agricultural
                                            activities. The Task Force members are
                                            committed to continue, within these existing
                                            programs, current activities that contribute to
                                            meeting the goals of this plan, while increasing
                                            the targeting within this reassessment to fill
                                            gaps that are observed within the existing
                                            programs.

                                            However, while landowners, States and Federal
                                            agencies have undertaken numerous  nutrient
                                            reduction activities, these activities have
not resulted in a reduction of the hypoxic
zone. Resources are insufficient to attain
the goals of the Action Plan, and the lack of
resources is the primary barrier to  successful
implementation of the plan. Federal, state, and
local governments and non-governmental
organizations all have a role in the reduction
in the size of the hypoxic zone. To achieve
results, significant  resources must  be provided
and targeted toward implementing the
most effective nutrient reduction  actions in
Mississippi River Basin states with the greatest
loadings of nitrogen and phosphorus to the
Gulf. The difference between the results that
might be achieved using existing  programs
and resources and the results that would be
realized with additional legislative, regulatory,
or financial  support is considerable. These
specific, critical needs are summarized later
in this document and will be defined more
precisely in the Annual Operating  Plan that
accompanies this document. The  Annual
Operating Plan will also describe the interim
steps, funding  needs, and associated timeline
that will guide implementation of the eleven
actions listed in the final section of this Action
Plan.

   Water Quality Credit Trading Program

   The nutrient trading program administered by the Miami
   Conservancy District for the Great Miami River Watershed in
   Ohio allows National Pollutant Discharge Elimination System
   (NPDES) permitted dischargers to purchase credits from best
   management practices installed by upstream nonpoint sources
   (i.e., agricultural producers) to offset nutrient loadings. While no
   Total Maximum Daily Load (TMDL) is in place yet, point sources
   in the watershed are concerned that upstream nonpoint source
   loadings will result in a stringent TMDL in future years. The point
   sources are purchasing reductions upstream in order to improve
   water quality enough to lessen the stringency of or eliminate
   the need for a TMDL. The program also employs trade ratios
   to encourage early investing. The trades are administered in a
   reverse auction format, where nonpoint sources submit bids for
   the amount they will accept in order to implement practices.
   Currently, there are 28 projects and more than 112 tons
   (244,606 Ibs.) of nutrient reduction is targeted over the terms
   of the projects. Funded best management practices include
   conservation tillage, conservation crop rotation, conservation
   cover, milk house/cow lot treatment, pasture seeding/prescribed
   grazing, sod establishment, hayland, manure storage, grid
   sampling/variable rate technology, and filter strips.
Bottomland hardwood forests improve water quality by filtering and flushing nutrients and by
reducing sediment before it reaches open water.

Trends in Nitrogen and
Phosphorus in the Basin
With a twenty-year average (1985-2005)
annual stream flow of over 20,000 cubic
meters per second, the Mississippi River carries
large amounts of sediments and nutrients
from its watershed, resulting in large nutrient
loads* delivered to the Gulf of Mexico at the
river terminus. Nutrient loads vary greatly and
are positively related to streamflow. According
to the United States Geological Survey (USGS),
between  1985 and  2005, nutrient loads ranged
from lows of 810,000 metric tons of nitrogen
and 80,700 metric tons of phosphorus to
highs of 2,210,000 and 180,000 metric tons
of nitrogen and phosphorus, respectively
(Figure 3).

It is especially important to understand the
sources of these nutrient loads that flow
into the Gulf of Mexico. Analysis of five-year
averages, from 2001-2005, of nutrient loads
from the various sub-basins indicates that
of the nitrogen load delivered to the Gulf of
Mexico came from  the Ohio/Tennessee and
*Load (often called flux) is the amount (mass) of a chemical in a river
that passes a given point over a given period of time. It is calculated
by multiplying the average streamflow (discharge) of the river by the
average concentration of that chemical in the river over that time period.

Upper Mississippi River Sub-basins (Figure
4), which contributed 41% and 39% of the
load, respectively. Similar analysis shows that
from 2001-2005, the Ohio/Tennessee and
Upper Mississippi River Sub-basins were the
greatest contributors of phosphorus loads to
the Gulf of Mexico as well, contributing 38%
and 26%, respectively (Figure 5). The Missouri/
Platte, Lower Mississippi, and Arkansas/Red
Sub-basins contributed 20%, 10%, and 6%,
respectively.

Figures 6 and 7 show both the long term
average and the most recent 5-year average
(for which data is available) nitrogen and
phosphorus loads for each sub-basin in the
Mississippi/Atchafalaya River Basin.

Overall, total annual loads to the Gulf from
2001-2005 show a 21% decline in nitrogen
load and a 12% increase in phosphorus
load when compared to the average from
the 1980-1996 period. However, during the
spring period (April, May, and June) most of
the reduction in total nitrogen load was from
nitrogen forms other than nitrate, an important
form fueling the primary production that leads
to hypoxia development in the spring.

Progress on Actions in the
2001 Action Plan
Of the eleven actions identified in the 2007
Action Plan, several have made significant
progress:

   The States established Sub-Basin
   Committees for the Upper Mississippi Basin,
   the Ohio Basin and the Lower Mississippi
   Basin. These committees have worked to
   coordinate actions in the sub-basin states.
   The Sub-Basin Committees have opened
   the discussion to include many stakeholders
   not represented on the Task Force, including
   additional  basin states, state agencies,
   and interested parties and  organizations.
   (Action 2 of 2001 Action Plan)

   The Task Force issued an integrated
   monitoring, modeling and research strategy
   (MMR workgroup report), for the Basin
   and Gulf to guide the development of
   the nutrient  reduction strategies as well
   as future scientific research. The MMR
   workgroup report was a driver for research
   strategies of the National Oceanic and
   Atmospheric Administration's (NOAA)

  After detailed planning and building
  on the recommendations of the MMR
  workgroup report,  NOAA conducted
  additional monitoring of the hypoxic zone
  on a seasonal and annual basis, though this
  has not "greatly expanded" the long-term
  monitoring program, as many important

Moving Forward on Gulf Hypoxia
   Mif
   In the Fall of 2007, USDA enrolled farmland in Minnesota as the one millionth
   acre in its nationwide Conservation Reserve Enhancement Program (CREP).

   CREP is a community-based, results-oriented effort that focuses on local
   participation and leadership and addresses high-priority conservation issues of
   both local and national significance, such as impacts to water supplies, loss of
   critical habitat for threatened and endangered wildlife species, soil erosion, and
   reduced habitat for fish populations.

   As a component of USDA's Conservation Reserve Program administered by the
   Farm Service Agency, CREP is a voluntary land retirement program that helps
   agricultural producers protect environmentally sensitive land, decrease erosion,
   restore wildlife habitat and safeguard ground and surface water. Partnering
   with tribal, state and federal governments and private groups, USDA establishes
   contracts with agricultural producers to retire highly erodible and other
   sensitive cropland and pastureland. During the 10- to 15-year contract period,
   participants convert enrolled land to grass, trees, wetlands, wildlife cover and
   other conservation uses. CREP supports increased conservation practices such
   as filter strips and forested buffers, which help  protect streams, lakes and rivers
   from sedimentation and agricultural runoff.

   Farmers in local communities deserve much  of the credit for CREP's
   overwhelming success. Without their commitment to CREP, this innovative
   program would not have reached this milestone.
Higher resolution spatial data were added
to large watershed-scale models to help
identify smaller watersheds for focused
nutrient reduction efforts. (Action 5of2001

The Ohio and the Lower Mississippi Sub-
Basins began development of nutrient
reduction strategies at the sub-basin level,
incorporating specific issues and proposals
from the states within those basins. (Action
6 of2001 Action Plan)

Increased  assistance to agricultural
producers through U.S. Department of
Agriculture (USDA) programs for voluntary
actions  resulted in an additional  1.4 million
acres  of wetlands restored, enhanced, or
created  and an additional 2.3 million acres
of conservation buffers installed  within in
the Basin during fiscal years 2000-2006.

• The Task Force completed a major
  reassessment of the science and actions
  to support the Action Plan principle of
  adaptive management. (Action 11 of2001
  Action Plan)

However, some of the actions called for in the
2001 plan have not been initiated, authorized
or completed:

  An integrated  federal budget that would
  have supported voluntary actions to reduce
  nutrient pollution in the Basin and thereby
  the size of the hypoxiczone in the Gulf was
  never finalized. (Action 1 of2001 Action Plan)

  The long-term monitoring program for
  the hypoxic zone has not been "greatly
  expanded," and uncertainties remain in
the ability to characterize the spatial and
temporal dynamics of hypoxia and the
biological, chemical, and physical properties
that contribute to it. (Action 4 of2001 Action
Plan)

Water quality monitoring in the Basin has
not significantly increased and in some
cases long term stations included in the
USGS network have been discontinued.
(Action 5 of2001 Action Plan)

Although some work has begun on the
development of nutrient strategies at the
sub-basin level,  much work still needs to be
accomplished. (Action 6 of2001 Action Plan)

Congress did not authorize and fund a
reconnaissance-level study for the U.S.

          Moving Forward on Gulf Hypoxia
With a commitment greater than $12.5
million since 2001, NOAA has continued
to provide the scientific foundation on
Gulf of Mexico ecosystem dynamics upon
which management of the hypoxic zone is
based. As part of this commitment, annual
monitoring of the hypoxic zone provides
the benchmark for which progress on
Action Plan goals is measured. Utilizing an
ecosystem-based approach, NOAA research
studies have led to enhanced predictive
models capable of examining a multitude
of interacting factors on the size of the
hypoxic zone, and provide information
on how hypoxia affects commercially and
ecologically important species in the region.
These models are integrating oceanographic
physical data and coastal biogeochemistry
to improve quantification of the duration,
timing, and extent of the hypoxic zone,
and their relationship to causative factors
such as nutrients and stratification. These
model predictions of complex processes will
continue to allow for the comprehensive
assessment of alternative management
strategies to mitigate hypoxia in the Gulf of
Mexico.
   Additional analysis of detailed nutrient
   pollution contributions from multiple
   sectors, including point sources and non-
   agricultural contributions, needs to be
   undertaken. (Action 8 of2001 Action Plan)

            the
The Task Force undertook a major
reassessment of the state of the science for the
causes, effects, and management actions for
reducing Gulf hypoxia.

   In the fall of 2006, the Task Force agencies
   and the Sub-Basin Committees completed
   a series of four scientific symposia on the
   science surrounding Gulf hypoxia and
   nutrient sources, fate, and transport in the
   Mississippi/Atchafalaya  River Basin.

   The Task Force completed a major
   technical report, A Science Strategy to
   Support Management Decisions Related to
   Hypoxia in the Northern  Gulf of Mexico and
   Excess Nutrients in the Mississippi River Basin
   (MMR workgroup report), published in
   2004. The report describes a framework
   for monitoring, modeling, and research
   activities to support management decisions
   related to  achieving the three major goals
of the 2007 Action Plan. It describes the
scientific information needed to support
management actions and defines the
scope, interrelation, and framework of
the activities needed to provide that
information. It also describes existing
programs  and activities, identifies gaps and
limitations in those activities, and outlines
the actions and resources needed to
overcome the gaps and limitations.

The Task Force completed a second major
technical report, The Management Action
Review Team report, published in 2006.
The report is a compilation of information
on point sources in the Mississippi  River
Basin and  available programs that assist
landowners, municipalities, and others
in the Basin to reduce nutrient loadings.
It also shows how such programs could
more effectively address nutrient reduction
if they were aligned and  integrated with
the Action Plan. The Management Action
ReviewTeam report represents the first time
the Task Force has compiled a snapshot
of programmatic information, and thus
it can  be used as a resource for future
reassessments.

   In August 2006, the Task Force asked
   EPA's Science Advisory Board to provide
   independent advice on scientific advances
   since 2000 that might have increased
   understanding and options in three general
   areas:

   *   Characterization of the causes of
       hypoxia. The physical, biological, and
       chemical processes that affect the
       development, persistence, and extent
       of hypoxia  in the Northern Gulf of
       Mexico.


  2   Characterization of nutrient fate,
       transport, and sources. Nutrient
       loadings, fate, transport, and sources
       in the Mississippi River that affect Gulf
       hypoxia.


   9   Scientific basis for goals and
       management options. The scientific
       basis for, and recommended  revisions
       to, the goals proposed in the 2007
       Action Plan; as well as the scientific
       basis for the efficacy of recommended
       management actions to reduce
       nutrient load from  point and nonpoint
       sources.
Conclusions from the
Reassessment
Taken together, the state-of-the-science
symposia, MMR workgroup report,
Management Action Review Team report,
and Science Advisory Board findings have
advanced our understanding of hypoxia in the
Northern Gulf of Mexico, as well as the factors
contributing to it. Based on the complete
reassessment of the science, the Task Force has
agreed on the  following main points which
inform the actions in this plan:

   It is extremely important to accelerate
   actions that manage factors affecting
   hypoxia rather than waiting while science
   develops greater precision in revising the
   appropriate  size goal for the  hypoxic zone.

   The 5,000 square kilometer size of the
   hypoxic zone, the Coastal Goal set by the
   2007 Action Plan, remains a reasonable
   goal in an adaptive management context;
   however, it may not be possible to achieve
   this goal by  2015. The hypoxic zone,
   measured in July 2007, was the third largest
   measured.
                                               Contour farming, conservation tillage, and conservation

                                                    that are critical to the stratification
                                                    which is necessary for hypoxia.
                                                    The diversion of a large amount of
                                                    freshwater from the Mississippi River
                                                    through the Atchafalaya has profoundly
                                                    modified the spatial distribution of
    freshwater inputs, nutrient loadings,
    and stratification on the Louisiana-
    Texas continental shelf.

Hypoxia has negative impacts on marine
resources. Research on the deleterious
effects of hypoxia on living resources in the
Gulf suggests the occurrence of long term,
ecological changes in species diversity,
and possibly a regime shift (a large-scale,
often  rapid, reorganization of the entire
ecosystem's food-web that is difficult and
often  impossible to reverse).

Phosphorus also contributes  to hypoxia.
New information has emerged that
more  precisely demonstrates the role of
phosphorus in determining the size of
the hypoxic zone, requiring strategies that
address both nitrogen and phosphorus.

Significant reductions in nitrogen and
phosphorus are needed. To achieve the
Coastal Goal for the size of the hypoxic zone
and improve water quality in the Basin, a
dual nutrient strategy targeting at least a
45% reduction in riverine total nitrogen
load and in riverine total phosphorus load,
                                                                     Mississippi River/Gulf of Mexico Watershed Nutrient Task Force • Gulf Hypoxia Action Plan 2008

   measured against the average load over the
   1980-1996 time period, may be necessary.

   Total annual loads to the Gulf from
   2001-2005 show a 21% decline in nitrogen
   load and a 12% increase in phosphorus
   load when compared to averages from
   the 1980-1996 period. However, during
   the spring period (April, May, and June)
   most of the reduction in total nitrogen
   load was from nitrogen forms other than
   nitrate, an important form fueling the
   primary production that leads to hypoxia
   development in the spring.

   Considerations of seasonality and nitrogen
   composition should be emphasized in
   nutrient reduction strategies. Recent
   scientific findings have affirmed that spring
   (April, May, and June) nitrate load from
   the Mississippi/Atchafalaya River Basin to
   the Gulf is highly correlated with hypoxic
   zone size. From 2001-2005, nitrate load to
   the Gulf during the spring  period may not
   have changed significantly when compared
   to averages from the 1980-1996 period,
   despite a 21% decline in total annual
   nitrogen load and a 12% increase in total
   annual phosphorus load.
New estimates of point and nonpoint source
contributions are available. Point sources
represented 22% of nitrogen and 34% of
phosphorus loads, resulting in a higher
percentage of the total load to the Gulf
from point sources than estimated in 1999.
Estimates of the point source load would
be at the upper end of the range, as they
assume delivery to the Gulf without any in-
stream losses. Nonpoint sources, including
atmospheric deposition, represented 78%
of nitrogen and 66% of phosphorus loads;
accordingly, these numbers would be at the
lower end of the range.

Anthropogenic nitrogen and  phosphorus
contributions have declined. Net
anthropogenic nitrogen inputs (NANI)  and
net phosphorus inputs for the Mississippi/
Atchafalaya River Basin have declined in the
last decade because of more  efficient use
of fertilizer (as evidenced by increasing corn
harvest and constant or declining fertilizer
application rates). From 1999-2005, NANI
calculations show 54% of nonpoint nitrogen
inputs in the Mississippi/Atchafalaya River
Basin were from fertilizer, 37% from fixation,
and 9% from atmospheric deposition.

Industrial Nutrient Discharge
Reductions

Recognizing the impacts of nutrient pollution on the
hypoxic zone in the Gulf, the Louisiana Department
of Environmental Quality (LDEQ) works with
industries and municipalities along the Mississippi
River to reduce nutrient discharges, consistent
with Action 8 of the 2007 Action Plan. Voluntary
programs, like the Louisiana Environmental
Leadership Pollution Prevention Program (LaELP)
engage professional, environmental, industrial,
and municipal associations to improve the quality
of the environment through pollution prevention,
community environmental outreach, and
environmental management.

Since 2000, the LaELP has recognized three
industrial businesses for significant nutrient
discharge reductions: IMC Phosphates (now Mosaic
Industries), BASF Corporation, and ExxonMobil.
Both BASF Corporation and IMC Phosphates have
been acknowledged with "Special Recognition
for Outstanding Nutrient  Reductions," a category
created to highlight Louisiana's special concern
for hypoxia in the Gulf of Mexico and to
emphasize the need for nutrient reductions.

Two IMC-Agrico plants were recognized for
implementing a comprehensive, long range by-
product management improvement campaign.
This provides inactive phosphogypsum stacks
with a synthetic liner and a clay/grass cover, and
has resulted in more than an 80% reduction, over
100 million Ibs., in average annual phosphorus
discharges. While the program was voluntary,
IMC-Agrico agreed to place the reductions in
permits to ensure long-term compliance.

BASF Corporation was recognized for developing
a biological treatment system that converts
nitrates in wastewater — that would otherwise
have been discharged to the Mississippi River
— to atmospheric nitrogen and other non-
nutrient parameters. Specifically, a new process
was added that completed the denitrification
process using "anoxic treatment" and specific
bacteria that live in low oxygen environments
that break down nitrates. The result has been an
annual reduction of over 23 million Ibs. of nitrates
in BASF's permitted discharged wastewater
since implementation began in 1999. BASF has
transferred ownership of the process to the Water
Environment Research  Foundation for wider use.
The ExxonMobil Baton Rouge Refinery, the second
largest petroleum refinery in the nation, was
recognized by both the LaELP and the EPA's Gulf
Guardian Award for reducing annual nitrate
discharges from 4.1 million Ibs. in 1999 to 1.5
million Ibs. in 2003. ExxonMobil's management
team established a nitrate reduction objective
and supported it through a five-year effort that
included an extensive engineering analysis. As
a result of the analysis, process operations were
modified to run two ammonia strippers in parallel
and the refinery wastewater treatment facility
began operating under anoxic conditions. This
reduction effort was not only voluntary, but was
achieved without capital expenditure.

Recently, the Secretary of LDEQ reaffirmed
the Department's commitment to the many
objectives of the LaELP and the special nutrient
reduction effort in particular. As a result, the
LaELP will continue to recognize activities
and projects that demonstrate environmental
leadership including innovative pollution
prevention efforts implemented by its partners
to reduce point source nutrient discharges to the
Mississippi River.

To reduce the size and impacts of the hypoxic
zone and improve water quality in the
Mississippi/Atchafalaya River Basin, landowners
and resource managers must reduce nitrogen
and phosphorus in the surface waters of the
Mississippi/Atchafalaya River Basin. Although
many other natural and seasonal factors
contribute to the formation of the hypoxic
zone, reducing nutrient loadings from the
various sources in the Basin addresses the
most critical and controllable cause of hypoxia.
No single action or strategy will  achieve the
necessary reductions. The optimal approach
will take advantage of the full range and
variety of actions to reduce nutrient loss to
waters and increase nutrient retention and
removal.

The work of the Task Force will continue to
provide a basin-wide context for the continued
pursuit of both voluntary, incentive-based
efforts for nonpoint sources and existing
regulatory controls for point sources. Improved
coordination and, in most cases, continued
expansion of the outstanding private and
government supported efforts to reduce
losses of nutrients are central to the success
of this strategy. Throughout the Mississippi/
Atchafalaya River Basin much work is
underway to increase the efficiency of farming

                                 practices, reduce point and nonpoint sources
                                 of pollution, and restore wetlands and riparian
                                 buffers. Landowners and managers primarily
                                 are taking these actions to achieve local water
                                 quality goals or implement conservation
                                 practices and management practices.

                                 Even though current activities of landowners
                                 and managers will contribute to reducing the
                                 size of the hypoxic zone and improving  basin
                                 water quality, they are not  sufficient to meet
                                 the goals of this plan. Current funding for the
                                 necessary actions is insufficient. In addition,
                                 emerging issues, such as biofuels, climate
                                 change, changes in  agricultural practices,
                                 and new technologies for monitoring and
                                 modeling will have significant effects on
                                 the design and implementation of this plan.
                                 The Task Force has identified the actions
                                 listed below to encourage and advance the
                                 continued implementation of cost-effective,
                                 voluntary, incentive-based best management
                                 practices and conservation practices at the
                                 local and regional level—actions to both
reduce loss of nutrients into the water and
to reduce those loads once they exist. These
actions are intended to support and add
greater specificity to the actions  begun under
the 2007 Action Plan.

Following each action are the reasons for
the action, the key players, and the process
for implementing the action. Because many
of these actions are beyond the scope of
existing state and federal water quality and
conservation efforts, they will achieve only
limited progress without additional financial
(and  in some cases legislative) support.
Therefore, the plan also includes a description
of the "critical needs"—additional funding
and analyses that are essential to achieve
significant reductions in the size  of the hypoxic
zone. The Task Force is committed to meeting
these critical needs, wherever possible, and is
publishing a separate, more detailed Operating
Plan to guide the implementation of these
actions.

   Phosphorus Reduction

   Phosphorus is the nutrient primarily responsible for the eutrophication of Minnesota's
   surface waters. An overabundance of phosphorus results in excessive algal production in
   Minnesota waters. In response to a dissolved oxygen TMDL on the Lower Minnesota River,
   Minnesota developed the Statewide Phosphorus Report which quantifies the phosphorus
   loading to Minnesota waters from various point and nonpoint sources. In 2005, Minnesota
   developed a Phosphorus General Permit for forty point sources in the Minnesota River
   Basin. Under the permit, the point sources have the option of trading to meet their water
   quality-based effluent limits.

   The Metropolitan Council owns and operates eight municipal wastewater treatment plants
   in the Twin Cities metropolitan area of St. Paul and Minneapolis. Since 1990, the Council has
   achieved dramatic reduction in phosphorus discharged from its plants to area receiving
   waters. Since the peak of phosphorus discharge in 1995, the Council has achieved a 78%
   reduction in phosphorus loads.

   To understand the magnitude of such a reduction, it would be as if we went back to before
   1900. At that time, the metropolitan area had a population of 500,000 people and it is
   estimated that 1,860 Ibs/day of phosphorus was discharged to area rivers. Today, 2 million
   more people live in this area, yet discharge only 1,670 Ibs/day.
                                                                                               Farmers use a line-transect method of determining the
                                                                                               percentage of ground covered by crop residues for soil

           Because the soils, hydrology, land use, and cropping practices
           as well as the legal, legislative, and administrative framework
           vary considerably across the 31 states in the Basin, the Task Force
           recognizes that no single approach to nutrient reduction would
           be effective in every state. All states already have programs to
           reduce nutrient losses from both point and nonpoint sources.
           However, while most states have plans within those programs
           to reduce their water quality problems, those plans are often
           focused  on local or regional water quality. Existing plans may
           need to  be modified to incorporate nitrogen and phosphorus
           reduction activities within the state to reduce loadings to the
           Gulf, while continuing to protect and restore local water quality.
           These strategies will provide a road map for each state, a more
           detailed  basis for budget development and implementation, and
           a vehicle for coordination with other states in the Basin. Once
           the state strategies are developed and adopted by the broad
           reach  of stakeholders throughout each state, and new funding
is provided, Federal and State agencies and many involved
stakeholders can accelerate their efforts to reduce nutrient
impacts on local waters and the Gulf.

State nutrient reduction strategies should be completed as
soon as possible but no later than 2013. Strategies should target

pollution control efforts should continue,
while states, in collaboration with other states
in the Basin and Federal agencies, complete
the strategies and seek necessary funding.
Implementation of the state strategies should
be started as soon as practicable, but no
later than 2013. The development of state
nutrient reduction strategies as prescribed
by this plan is to be complementary to, and
shall in no way delay or interfere with the
progress of any existing or planned nutrient
reduction activities, or identification of priority
watersheds. To further advance progress,
the States should  provide a list of activities
for incorporation into the Annual Operating
Plans, identifying planned nutrient reduction
activities and the corresponding availability
and needs for funding.

Implementation of the Action Plan will
require a significant level of commitment
from the Federal agencies and State and local
governments, and increased awareness and
action by the many varied stakeholders. Existing
relationships with key stakeholders should
be maintained and additional relationships
developed with other stakeholders to develop
and implement strategies to reduce nutrient
loads to the Gulf of Mexico and to water
bodies within the Basin. The States are uniquely
qualified to identify the key stakeholders within
their states who can influence opinion and
support needed changes in practices and
programs. State agencies have established
relationships with their constituents, whether
agricultural producers or regulated entities such
as wastewater facilities. This approach will allow
Federal and State  agencies and stakeholders
in each state to focus on activities that will be
most effective in their area.
Federal agencies, working with the States
and the Sub-Basin Committees, will need to
establish  incentives through the 319 program,
Farm Bill programs, or other federal funding
sources to provide additional resources for the
development and implementation of state-
level nutrient reduction strategies.

The States and Federal agencies must
coordinate efforts across organizations and
programs and use adaptive management to
modify the strategies as new information and
innovative solutions are acquired to identify
critical watersheds, assess current conditions,
and maximize potential nitrogen and
phosphorus reductions with the most cost-
effective approaches.
Since 2005, over $1 million
has been provided to landowners
in Arkansas for installation of
on-farm structures to reduce
sediment and nutrient runoff. These
projects have been implemented
in the Arkansas River and Bayou
Bartholomew/Beouf-Tensas basins.
Overwhelming public participation
and interest has created additional
opportunities for implementation
of nutrient reduction programs in
other Mississippi River tributary
watersheds.

Federal agencies have significant programs and projects that
affect water quality in the Gulf and locally throughout the
Basin. In some cases a Federal agency may have direct lead
fora specific activity, such as management of water flow and
navigation on large, interstate rivers or management of fisheries.
In other cases federal  programs help to set the parameters of
programs that are co-implemented or delegated to states, such
as technology standards for wastewater treatment or criteria
used as the basis for water quality standards. Broader federal
strategies are also needed to establish a context and approach
to guide and coordinate the actions of these other partners.
These strategies could include programs to identify effective
nutrient reduction approaches, including streamlining regulatory
requirements, utilizing innovative funding mechanisms, and
implementing best management  practices. For example, a
federal strategy for  restoration of the Mississippi/Atchafalaya
River Basin's natural assimilative system would facilitate and help
coordinate federal and state actions to implement the plan.
These federal, basin-level strategies will help set a framework
for individual state action and support collaborative efforts for
program planning and implementation.
Federal agencies, Mississippi/Atchafalaya River Basin States
Sub-basin Committees, other regional groups
Federal strategies for programs and projects with the greatest
impact on nutrient levels within the Basin should be identified
by June 2008 and completed by 2009. As part of the strategy,
Federal agencies will identify opportunities to align existing
programs with hypoxia efforts. For example, the USAGE should

look for opportunities to reduce nutrient
loadings related to Corps projects and
programs, ensure that environmental and
related documents specifically address the
hypoxia impact, and take advantage of
environmental projects to create wetlands and
reconnect backwater and riparian zone areas
to absorb nutrients. Efforts should be made to
better engage the research and development
expertise in the Corps with regard to  reducing
nutrient loadings related to Corps civil works
projects. Another example is for EPA to provide
direct financial and technical support to its
state partners in the Mississippi/Atchafalaya
River Basin as they develop a scientific basis to
assist in the adoption of state numeric nutrient
standards. These cooperative efforts not only
will serve to assist the states in protecting
in-state water quality, but also may result in
reduced nutrient loadings to the Gulf. More
detail on each  agency's effort is documented
in the Annual Operating Plan.

WHAT ARE THE CRITICAL
NEEDS?
The opportunity may exist through the
implementation of the 2007 Farm Bill for
additional conservation technical assistance,
including rapid watershed assessments to help
prioritize use of limited financial assistance
for producers, establishing a Regional Water
Enhancement Program to provide funding to
support development and implementation
of water quality plans at the watershed scale,
providing funding to support conservation
innovation addressing nutrient reductions,
and additional funding for working lands
(Environmental Quality Incentive Program)
and wetland restoration, creation, and
enhancement (Conservation Reserve Program/
Wetlands Reserve Program/Conservation
Technical Assistance).

Ongoing analysis of the impacts of emerging
issues on water quality, such as the increased
production of biofuels, will also be critical
to ensure that the nitrogen and phosphorus
strategies will continue to improve water
quality in the Mississippi/Atchafalaya River
Basin and ultimately the Gulf of Mexico.

Additionally, an interagency coordination
strategy to leverage USDA, EPA, USAGE, and
other funding mechanisms to eliminate
financial barriers for private landowners
implementing conservation practices to
address nutrient runoff from neighboring
properties will aid in the implementation of
these federal strategies.
Managing sediment sustains economic activity and can
contribute to ecosystem restoration and protection.

For programs whose primary intent is not to mitigate hypoxia,
such as wildlife habitat enhancement, conservation practices,
navigation controls, or wastewater discharge permits,
incorporating considerations of additional benefits into
implementation decisions can result in the "win-win" outcome
of adding increased nutrient retention and capture benefits
to these programs, and consequently improving water quality
downstream and in the Gulf.

The guiding principle of this plan is that when establishing
priorities for watershed restoration, States, Tribes, and Federal
agencies within the Mississippi/Atchafalaya River Basin will
consider the potential for benefits to the Gulf of Mexico. This
principle is especially important in the context of changes in
agricultural markets such as the increased demand for corn
for ethanol production that could  have a substantial effect on
nutrients delivered to the Gulf. Many federal, state, and tribal
programs offer the opportunity to enhance nutrient reductions,
whether large water infrastructure projects or day-to-day
decisions on zoning, permitting, and land use planning. However,
most state, tribal, and federal projects usually only address local
water quality concerns. Support for approaches that protect local
water quality, including drinking water sources, can  be leveraged
to increase support for mitigating Gulf hypoxia. There is frequently
strong public support for protecting drinking water sources.
Public awareness and  support for local water quality benefits can
increase support for actions that ultimately reduce Gulf hypoxia.
These entities should consider this guiding principle, ensuring
that these projects, including land and river management
strategies, and flood control and navigation projects throughout
the Basin, examine their effect on Gulf hypoxia as well as look for
opportunities to increase the ability to reduce nutrients which
harm local waters, including drinking water sources, and the Gulf,
through design and operation changes.

Each Federal agency and State will identify
opportunities for implementing cost-effective
nutrient reduction through existing programs.
Two examples of how to do this are given
below, although there are many other
programs at each participating Federal agency
that will need to be included.

One example of this is the manner in
which USDA plans to address concerns
about the effect that increased biofuels
production will have on nutrient loads to
the Gulf. Management of agricultural lands
in the Mississippi River Basin is not static, but
invariably changes in response to changes
in the demand for agricultural commodities.
USDA provides technical and  financial
assistance to farmers and ranchers to help
them address environmental  concerns
associated with agriculture production.
The technical foundation for this assistance
is the development and application of
conservation practice standards through
several conservation programs that address
a wide variety of environmental issues in
addition to water quality. These programs are
designed to help maintain the sustainability
of agricultural lands regardless of their use.
Given the need for further reductions in
nutrient loads to the Gulf, in the delivery of its
programs within the Mississippi Basin, USDA
will place additional emphasis on conservation
practices with high potential for reducing
nutrient loadings. These conservation practices
include nutrient management, cover crops,
the siting of wetlands, and on-farm drainage
water management. This approach permits
agriculture production to adjust to meet
the changing needs of the market while
maintaining the sustainability of the resource
base and minimizing environmental effects.

USDA will encourage the increased use of its
nutrient management standard to minimize
nutrient loss from fields to help alleviate the
impact of increased biofuels production
on nutrient loads to the Gulf. The nutrient
management standard requires farmers to
account for all plant-available nutrient sources
immediately available or rendered available
throughout the crop production cycle

                                                 When heavy rains occur, unprotected farm fields can yield topsoil,
                                                       as well as farm fertilizers and other potential pollutants.
and to apply only the amount of nutrients
needed to maintain nutrient balances.
Nutrient applications needed to maintain
nutrient balances are based on  realistic yield
expectations and attempt to maximize
profitable production. The use of cellulosic
feedstocks, such as crop residues, perennial
grasses, and trees for biofuels production will
require utilization of different conservation
systems and conservation practice standards,
such as the one for residue management.
USDA will continue to adjust current standards
and develop additional standards, where
needed, to permit cellulosic feedstocks to  be
produced and utilized in a sustainable manner.

Another example is the massive coastal
protection/restoration program being
undertaken  by the State of Louisiana, the
federal government, and various stakeholder
groups. The most critical element of this
program involves retaining river sediment
and river-borne nutrients within the coastal
marshes to the greatest degree possible by
redistributing river water throughout the
delta before it reaches the Gulf of Mexico.
Diverting  river water into the deltaic system
on a large scale could provide an important
sink for some of the excess nutrients that

cause hypoxia through plant uptake, bacterial
processing, and sedimentation. In addition,
increasing the number of outlets for river
water could significantly increase mixing in the
coastal ocean and reduce salinity stratification
and the setup conditions for hypoxia. There
is substantial evidence that such a program
would save wetlands now in jeopardy and
increase productivity and sequestration of
both nutrients and carbon.
WHAT ARE THE CRITICAL
NEEDS?
   Identify barriers to aligning existing
   programs, projects, and initiatives with
   needs of hypoxia.

   Continue funding as defined by current
   budget requests for actions identified in the
   Annual Operating Plan.
While this apparent "win-win" strategy is
complex and expensive, authorization and
funding for Louisiana's critical river diversion
program has garnered broad public support.
There are, however, serious environmental
concerns about releasing huge volumes of
nutrient-rich river water into the estuarine
zone instead of into the nearshore ocean
where it goes today. Thus, river diversions
could be postponed until nutrient levels are
significantly reduced upstream, although
such postponement could undermine the
restoration of what has come to be known as
"America's Wetland."

Federal agencies will seek to further advance
science in the priority needs recommended
in the MMR workgroup and Science Advisory
Board reports. Furthermore, effective
implementation of this Action Plan will require
monitoring and tracking progress. Finally, the
2008 Action Plan is the result of several years
of study and discussion by the members of
the Task Force and many concerned officials,
organizations, and citizens who  participated
in the deliberations. Given the cooperative
and voluntary nature of the 2008 Action Plan,
its implementation will be dependent upon
broad acceptance and a willingness to pursue
the identified actions. The engagement  of
stakeholders will continue to be a priority.

The following actions implement the principle
of adaptive management for this strategy.

Understanding the most efficient and cost-effective conservation
practices and management practices to reduce nutrient loads
is central to the success of nutrient reduction strategies. Federal
and State agencies and other partners need to be able to
identify effective management practices and technologies,
including conservation practices and wastewater treatment at
the local scale, and large scale federal approaches to enhance
the biological removal of nutrients. We also need to incorporate
changing contexts in conservation practices and management
practices and accurately assess the economic costs and benefits
of different approaches.

Researchers have greatly expanded our understanding of
the effects of hypoxia. However much uncertainty remains,
specifically concerning the indirect biological and socioeconomic
effects of hypoxia and excess nutrients throughout the
Mississippi/Atchafalaya River Basin and on the Gulf.

As State and Federal agencies, and other partners make progress
reducing nutrient loads within the Basin, we need to better
understand the changes that are occurring, their effects on the
ecosystem and its economic resources, the costs and benefits
of seeking additional reductions in loads throughout the Basin,
and the additional effects that reductions in nitrogen and
phosphorus may have on the economic and social welfare of the
Mississippi/Atchafalaya River Basin.

Research into the impacts of the hypoxic zone on living
resources is authorized through the Harmful Algal Bloom and
Hypoxia Research and Control Act. Within the Gulf ecosystem
there is evidence that an ecological regime shift, associated
with the expansion of hypoxia in the Northern Gulf of Mexico,
has occurred. Effects of the hypoxic zone on fisheries and
ecologically important species are often likely to be indirect
and difficult to measure. Spatially-explicit ecosystem models are
needed to quantify these indirect effects and their consequences
on fisheries and ecologically important populations. Economic
analysis of these impacts will improve resource assessments and
help to better quantify the socioeconomic benefits of nutrient
reduction achievements in the Mississippi/Atchafalaya River Basin.

HOW DO WE DO THIS?
1  Conduct an economic assessment of
   alternative options for reducing nutrient
   loads;

2  Identify and assess the ancillary
   environmental effects of the alternative
   options for reducing nutrient loads;

3  Improve quantification of the indirect
   effects of hypoxia on living resources,
   especially those related to interactions with
   additional stressors (e.g., fishing and climate
   change), to inform model development
   and management strategies;

4  Quantify the socioeconomic effects of
   hypoxia on coastal communities along the
   Northern Gulf of Mexico, especially impacts
   to commercial  and recreational fisheries;

5  Quantify the socioeconomic effects on
   basin states from implementation of
   practices that will be required to meet the
   nutrient reduction goals of the Action Plan;
   and

   Track progress to support future science
   assessments.
WHAT ARE THE CRITICAL
NEEDS?
  Continued resource allocation for a USDA
  Hypoxia Economic Analysis to assess
  the socioeconomic and bioeconomic
  implications of varying nutrient
  management scenarios.

  Expansion of resources for ecological
  impact studies on commercially and
  ecologically important species, such
  as those funded by NOAA's Northern
  Gulf of Mexico Ecosystems and Hypoxia
  Assessment Program, to advance model
  capabilities that predict the impacts of
  hypoxia.

  Coordination and expansion of faunal
  monitoring surveys, such as SEAMAP, with
  increased  resource allocations for fishery-
  independent data on commercially and
  ecologically important fish and shellfish
  species.

• Quantified nutrient loading thresholds
  and corresponding ecological responses
  to determine the magnitude of ecological
  system resiliency (i.e., point of regime
  change) within the northern Gulf.
Hypoxia is one of many ecological stressors that can affect
Gulf fisheries and consequently fishing communities.

Current activities are unlikely to resolve serious
inconsistencies or provide additional data
from unmonitored sources. Additional work
is needed to define processes for acquiring,
documenting, storing, and accessing
data. Particularly, we need to develop and
implement programs to measure nitrogen and
phosphorus discharges from non-agricultural
sources for which data are not currently
collected, such as municipal water treatment
systems, and industrial, urban wet-weather,
and air deposition sources. We also need to
develop and implement strategies for using
NRI/CEAP to monitor progress regarding
reducing nutrient loads from agricultural land
management activities. We need to design
and implement a coordinated, ongoing state
and federal sustainable monitoring program as
recommended in the MMR workgroup report
for the hypoxic zone and for the fresh waters
of the Mississippi/Atchafalaya  River Basin that
would allow comprehensive temporal and
spatial data acquisition to assess progress.

Researchers have greatly expanded our understanding of the
physical dynamics of the Gulf of Mexico and the causes of
hypoxia, providing additional evidence that supports the strategy
to reduce the size of the hypoxic zone by reducing nutrient
loading to the Gulf. However, improved characterization of
nutrient load and hypoxic zone properties is needed to further
refine management strategies. As State and Federal agencies
and other partners make progress at reducing nutrient loads,
improved precision in understanding the effects of a dual
nutrient strategy for the hypoxic zone is needed to best inform
quantitative load reduction goals that will be required to reach
the Coastal Goal. Improvements in hypoxic zone monitoring are
needed to better characterize its magnitude and the processes
that lead to its development, maintenance, and distribution as
well as its impacts. Greater temporal  and spatial coverage in
monitoring efforts are needed to account for variability and pre-
cruise storm events, define boundaries, characterize seasonality,
and support modeling efforts. Improvements are needed in
the accuracy of models forecasting the quantitative association
between biological, chemical, and physical processes, and
hypoxia development, magnitude, and extent.

focus on:

   Creating and maintaining a Web site for
   accessing current information on Task
   Force activities, status of actions, and all

The Task Force Communications Plan can be
assembled using existing staff resources. Under
current levels of funding, communications
efforts will remain status quo and relatively
limited and will not meet the goal of
expanding public awareness of Gulf Hypoxia
and the publication of the Action Plan. To reach
a broader audience, several activities outlined
by the Task Force can be strengthened with
a relatively modest increase in funding by
engaging communications/media specialists
and increasing publication of communications
