Foreword
The U S Environmental Protection Agency (EPA) has developed this
document as a tool for state, tribal, regional, and local natural resource
managers who are preparing or considering the preparation of rapid
response action and/or management plans for aquatic invasive species (AIS).
The document provides an overview of EPA authorities that might apply to
state or local AIS rapid response and control actions. Note that development
of new rapid response or control methods and/or new judicial rulings could
alter the applicability of the EPA authorities described here and make other
EPA authorities relevant.

This tool does not cover other Federal agencies' authorities (e g the
Endangered Species Act and the Magnuson-Stevens Fishery Conservation
and Management Act) or state authorities that might apply to AIS rapid
response and control  actions.

This document does not represent final EPA action, is not intended to
supplant or replace regulations and/or guidance for the authorities described
in this document, and is not intended, nor can it be relied upon, to create any
rights enforceable by  any party in litigation with the United States

This document was developed in response to Executive Order 13112 on
Invasive Species (EO), signed on February 3, 1999, which orders "each
Federal agency whose actions may affect the status of invasive species
..  to identify such actions [and] use relevant programs and authorities to
detect and respond rapidly to and control populations in a cost-effective and
environmentally sound manner" (For the complete text of the EO, see

Introduction
Aquatic invasive species (AIS) are organisms introduced to   i
freshwater ecosystems to which they are not native and v>,-!i  E
causes harm to human health, the environment, or the ecoi k n
negative impacts on aquatic ecosystems throughout the Urine
costing the nation billions  of dollars annually in economic and >
damages.  AIS are considered one of the greatest threats to co,
environments and can significantly affect public water supplies
activities, such as boating; and valuable natural resources, sucn as fishei le;
Major pathways for AIS include:
   • discharge of ships'ballast water

   • fouling, such as barnacle growth,  on commercial and recreational
     vessels
   • accidental or intentional release of marine organisms intended for
     human consumption, aquaculture, bait, horticulture, aquaria, and the
     pet trade

   • escape or unintended spread of nonnative biocontrol species

Prevention of AIS introductions is generally the most effective means of
avoiding their establishment and spread. If prevention measures fail, the
following steps are critical to managing AIS establishment and spread:
     ^. routine monitoring of aquatic ecosystems to detect AIS before they
       become widespread
     2. rapid assessment of potential management options
     3. rapid response to eradicate or control AIS

In many cases, eradication ("rapid response") actions must occur quickly,
possibly even within a few days of the AIS introduction, to be effective. For
this reason, natural resource managers are advised to identify and evaluate
potential rapid response actions before species introductions even occur and
prepare detailed rapid response plans that can be carried out quickly. If both
prevention and rapid response actions fail, natural resource managers may
be able to prevent further proliferation and/or minimize harmful AIS impacts
by ongoing control of established AIS populations.

                                 Gymnocephalus cernuus, and alewife Alosa pseudoharengus, compete with
                                 native fish for food and habitat, significantly impacting Great Lakes food webs
                                 and sports fisheries.

                               • Nonnative plants, such as the common reed Phragmites australis, purple
                                 loosestrife Lythrum salicaria, and Eurasian milfoil Myriophyllum spicatum, have
                                 become established in the Great Lakes, displacing native plants that provide
                                 wildlife habitat and  prevent erosion. Their prevalence in recreational waters also
                                 hinders swimming and boating.

                               • The nonnative infectious oyster disease MSX has devastated native oyster
                                 populations along the U.S. East Coast.

                               • The nonnative green crab Carc/nus maenas competes with native fish and birds
                                 for food and preys on native bivalve populations along the U.S. West Coast,
                                 threatening Dungeness crab, clam, and oyster fisheries.

                               • The nonnative Chinese mitten crab Eriocheirsinensis burrows in  intertidal
                                 stream banks and levies in California, undermining the structural integrity of the
                                 banks and causing severe erosion problems.

                               • The nonnative freshwater weed water hyacinth Eichhornia crassipes forms
                                 dense mats at the surface of water bodies throughout the United States,
                                 decreasing surface flow and preventing light and oxygen from reaching
                                 phytoplankton and submerged plants.
                                       Caulerpa taxifolia is a highly invasive marine alga used to decorate
                                       saltwater aquaria. It is believed to have been introduced to several
                                       regions, including California, through aquaria releases. Once
                                       introduced, it spreads by fragmentation (even small fragments can
                                       form a new plant) and can form a dense carpet over rock, sand,
                                       and mud bottoms and native vegetation. It can also be transported
                                       between water bodies by boat anchors, fishing gear, and other
                                       equipment. In areas where it has become well-established, it has had
                                       a very detrimental impact on native marine communities,  recreational
                                       boating and diving, and commercial fisheries.

                                       Because C. taxifolia is easily spread and very difficult  to eradicate,
                                       public education about safe disposal of aquaria contents and routine
                                       checking and cleaning of boat anchors, hulls, rudders, trailers, and

 In 1988, zebra mussels Dreissena polymorpha were inadvertently
 introduced to Lake St. Clair near Detroit, Michigan, and quickly
 spread throughout the Great Lakes and into many inland lakes,
 rivers, and canals. Since then, they have caused severe problems
 at power plants and municipal water supplies, clogging intake
 screens, pipes, and cooling systems. They have also nearly
 eliminated native clam populations in the Great Lakes.

 To prevent the westward spread of zebra mussels and other AIS,
 the 100th Meridian Initiative, a cooperative effort between Federal,
 state, and Canadian provincial agencies, was started. The Initiative
 works to prevent the spread of zebra mussels by:
   • informing and educating the public about the biology and
     impacts of zebra mussels and pathways for spreading zebra
     mussels

   • voluntary boat inspections and boater surveys

   • establishing monitoring sites to detect the presence of
     zebra mussels

   • eradicating or containing zebra mussels if they are detected

                            Types of Rapid Response and Control Actions
                            There are three types of methods to eradicate and/or control AIS
                                 • Chemical methods involve the application of chemicals to eradicate
                                   and/or control AIS.

                                 • Mechanical and physical methods involve the eradication and/or
                                   control of AIS by hand or machine or the alteration of the physical
                                   environment. Examples of mechanical and physical rapid response
                                   and control actions for invasive plants include manual cutting or
                                   picking, mowing, dredging, and shading to prevent photosynthesis.
                                   Examples of mechanical and physical rapid response and control
                                   actions for invasive animals include netting or trapping, smothering,
                                   and changing ambient water temperature.

                                 • Biological methods involve the introduction of parasites, predators,
                                   or pathogens to the environment to control AIS. Biological methods
                                   are not generally considered rapid response methods because they
                                   typically take considerable time to develop and achieve results and
                                   they generally reduce, rather than eradicate, target populations.

                            The three types of eradication and control  methods are not mutually
                            exclusive because sometimes they can be used in combination and because
                            some actions  might belong to multiple categories  For example, the
                            application of  a saline solution to water bodies to eradicate or control AIS
                            could be considered both a chemical and a physical action.

Examples of Rapid Response and Control Actions
It can be very difficult to eradicate or control AIS because both AIS and
control agents, such as pesticides, are relatively easily spread. Examples of
successful rapid response and control actions in aquatic environments are.
   • The marine alga Caulerpa taxifo/ia, which is highly invasive in the
     Mediterranean, was eradicated from two coastal locations in southern
     California. Natural resource managers covered the C. taxifolia
     infestations with tarps and then injected chlorine beneath the tarps to
     destroy the alga (Chemical control method).
   • The marine mussel Mytilopsis sp., a close relative of the zebra
     mussel Dreissena polymorpha, was eradicated from Darwin Harbor in
     Australia. Chlorine and copper sulphate were added to the waters of
     three hydrauhcally and physically locked marinas, and fouled vessels
     that were inside the infested  marinas were hauled out and cleaned
     (Chemical and mechanical/physical  control methods).

1   • The northern  snakehead Channa argus, a large, nonnative predatory
     fish, was eradicated from several small ponds in Maryland. Herbicides
     were applied  to the ponds to remove potential fish refuges and then
     a piscicide was used to kill the snakeheads in the ponds (Chemical
     control method).

If rapid response actions are not initiated or do not result in AIS eradication,
ongoing control of  AIS could be very costly. While there is no credible,
comprehensive estimate of what AIS cost the United States economy, it
is estimated that control costs in the United States for the invasive marsh
weed European purple loosestrife Lythrum salicaria are $45 million annually,
and fouling damages in the United States from the invasive shipworm Teredo
navalis are $1 billion annually.1

                                                                                      Channa argus

                        A Tool for State and Local Natural Resource Managers
                        Because AIS can have substantial impacts on local environments and
                        economies, and states and localities are often the first responders to aquatic
                        invasions, EPA is providing this tool for state and local natural resource
                        managers. The document provides an overview of EPA authorities that might

                             Federal Insecticide,  Fungicide, and Rodenticide Act (FIFRA)

                           •  summarizes how to apply  for CWA Section 404 permits to discharge

Clean  Water  Act
What is the Clean Water Act (CWA)?
CWA is the cornerstone of surface water quality protectic n
States  The statute employs regulatory and nonregulator\  ti
broad goal of restoring and maintaining the chemical, ph\M
integrity of the nation's waters so that they can support the \
propagation of fish, shellfish, and wildlife and recreation in ar
CWA regulatory and nonregulatory tools are used to:

   • reduce direct pollutant discharges into waterways

   • finance municipal wastewater treatment facilities

   • manage polluted runoff
Currently, many of the tools used for surface water quality protection employ
the watershed approach, which focuses equally on protecting healthy waters
and restoring impaired ones. (For the complete text of the Clean Water Act,
see www. epa.gov/region5/water/pdf/ecwa.pdf.}

In  particular, CWA Section 404 might apply to AIS  rapid response or control
activities. Section 404, which regulates the discharge of dredged or fill
material, might apply to AIS eradication activities that involve moving dirt or
placing materials into the waters of the United States
 "Waters of the United States" means:
 • navigable-in-fact waters
 • waters subject to the ebb and flow of the tide
 • interstate waters and wetlands
 • all other waters, such as interstate lakes and streams, the use, destruction, or
   degradation of which could affect interstate commerce
 • impoundments of waters of the United States
 • tributaries of above waters
 • territorial seas
 • wetlands adjacent to above waters

 See 40 CFR 230.3(s) (www.access.gpo.gov/nara/cfr/waisidx_04/40cfr230_04.html]
 for precise regulatory definition. Updates and background information regarding
 the scope of "waters of the United  States" protected under the CWA can be
 found at www.epa.gov/owow/wetlands/guidance/SWANCC.
"Pollutant" means
dredged spoil, solid
waste, incinerator residue,

and discrete conveyance,
including but not limited to
any pipe, ditch, channel,
tunnel, conduit, well,
discrete fissure,  container,

                          Discharge Elimination System (NPDES)


                          What is CWA Section 402?
                          CWA Section 402 establishes the NPDES permit program to regulate point
                          source discharges of pollutants into waters of the United States. An NPDES
                          permit sets specific discharge limits for point sources discharging pollutants
                          into waters of the United States and establishes monitoring and reporting
                          requirements, as well as special conditions  (For more information about the
                          NPDES permit program, see http://cfpub.epa.gov/npdes.}

                          EPA is charged with administering the NPDES permit program, but can
                          authorize states to assume many of the permitting, administrative, and
                          enforcement responsibilities of the NPDES permit program. Authorized
                          states are prohibited from adopting standards that are less stringent than
                          those established under the Federal NPDES permit program, but may adopt
                          or enforce standards that are more stringent than the Federal standards if

                          An interpretive statement issued by EPA in January 2005 stated that the
                          application of a pesticide to waters of the  United States consistent with
                          all relevant requirements under the Federal Insecticide, Fungicide, and
                          Rodenticide Act (FIFRA) does not  constitute the discharge of a pollutant (and
                          consequently does not require a Federal NPDES permit) in the following two
                          circumstances.
                             • the application of pesticides directly to waters of the United States to
                                control  pests.  Examples  of such applications include applications to
                                control  mosquito larvae,  aquatic weeds,  or other pests that are present
                                in the waters of the United States.

                             • the application of pesticides to control pests that are present over
                                waters of the United States, including  near such waters; that results

                     CWA Section 404—Permits to Discharge
                     Dredged or Fill Material

                     What is CWA Section 404?
                     CWA Section 404 establishes a program to regulate the discharge of
                     dredged and fill material into waters of the United States, including wetlands.
                     Responsibility for administering and enforcing Section 404 is shared by the
                     U S  Army Corps of Engineers (USAGE) and EPA. USAGE administers the
                     day-to-day program, including individual permit decisions and jurisdictional
                     determinations; develops policy and  guidance; and enforces Section 404
                     provisions EPA develops and interprets environmental  criteria used in
                     evaluating permit applications, identifies activities that are exempt from
                     permitting, reviews/comments on individual permit applications, enforces
                     Section 404 provisions, and has authority to veto USAGE permit decisions.
                     (See www.epa.gov/owow/wet/ands/facts/fact10.htm/ior additional
                     information about CWA Section 404, and www.usace.army.mil/inet/

                     USAGE Regulatory Program.)

                     With EPA approval and oversight, states and tribes can assume
                     administration of the Section 404 permit program in certain "nonnavigable"
                     waters within their jurisdiction. At the time of publication, only Michigan and
                     New Jersey have done this. In those two states, USAGE retains jurisdiction
                     in tidal and navigable waters and their adjacent wetlands.

When does CWA Section 404 apply to A/S rapid response or
control actions?
It is possible that some mechanical/physical AIS rapid response and control
methods, such as the mechanized clearing of riparian areas to remove AIS or
dumping of fill material to smother AIS, might require Federal or state Section
404 permits. EPA and  USAGE have issued a rule stating that they regard the
use of mechanized  earth-moving equipment to conduct activities in waters of
the United States (e.g. land clearing,  ditching, channelization, and m-stream
mining) as regulated discharge of dredged or fill material under Section 404
unless project-specific evidence shows otherwise.

USAGE regulatory program management and administration is focused at the
District office level, with  policy oversight at higher levels. District Engineers
are authorized to issue permits, including standard permits, letters of
permission, and regional  general permits  Division Engineers may also issue
permits under certain circumstances. USAGE also issues nationwide permits
that authorize certain activities that result in minimal adverse environmental
effects  Natural resource managers should consult the appropriate USAGE
District office when planning AIS rapid response or control actions to
determine if these actions require a Federal Section 404 permit. (See
www.usace.army.mil/inet/functions/cw/cecwo/reg/district1.htm for contact
information for USAGE District offices.) In Michigan and New Jersey, natural
resource managers should also consult their state Section 404 authorities
when planning AIS  rapid  response or control actions to determine if these
actions require a  state Section 404 permit.

How do I apply for a CWA Section 404 permit?
There are several ways in which activities requiring Section 404 permits can
be authorized.
   •  Standard permits can be issued in situations where, after a public
     notice and comment period, the USAGE District Engineer determines
     that the proposed activity is not contrary to the public interest. USAGE
     issues a public notice within 15 days of receiving a completed permit
     application. The public notice describes the proposed activity, its
     location, and potential environmental impacts and invites comments
     within a specified time period, typically 15 to 30 days. The public at
     large, as well as interested  Federal,  state, and local agencies, have an
     opportunity to comment on the proposed activity.                     *J .  *

     large is not Section 404 letters of permission can be issued only in
     cases where, after consulting with certain Federal and state agencies,
     the USAGE District Engineer has previously approved categories of
     activities that can be authorized by letter of permission procedures.
     Requesting a letter of permission may be an appropriate and relatively
     expedient means of complying with Section 404 for many relatively
     localized and non-controversial AIS rapid response or control actions
     that require Section 404 compliance.

   •  General  permits are often issued by USAGE for categories of activities
     that are  similar in nature and would have only minimal individual
     or cumulative adverse environmental effects. General permits
     can be issued on a nationwide ("nationwide permit") or regional
     ("regional general permit") basis A general permit can also be
     issued on a programmatic basis ("programmatic general permit") to
     avoid duplication of permits for state, local or other Federal agency
     programs. The mechanized clearing of riparian areas for the control of
     invasive species  may be authorized by a nationwide permit, but the
     appropriate USAGE  District office should be contacted to determine if a
     nationwide permit can be used to authorize a specific activity In some
     USAGE Districts, nationwide permits have been suspended or revoked,
     and Section 404  standard permits, letters of permission, regional
     general  permits,  or programmatic general permits are used instead.

In general, to obtain a Section 404 permit, applicants must demonstrate that
the discharge of dredged or fill material would not significantly degrade the
nation's waters and there are  no practicable alternatives less damaging to the
aquatic environment. Applicants should also describe steps taken to minimize
impacts to water bodies and wetlands and  provide appropriate and practicable
mitigation, such as restoring  or creating wetlands, for any remaining,
unavoidable impacts. Permits will not be granted for proposals that are
found to be contrary to the public interest. In the case of AIS rapid response
or control actions, the  removal of AIS or mitigation of their harmful effects
could be considered a  benefit of the action. Compliance with the Endangered
Species Act and/or Section 106 of the National Historic Preservation Act may
also  be required  before a Section 404 permit can  be issued.

On average, individual permit decisions (standard permits and letters of
permission) are made  within  2 to 6 months from receipt of a completed
application. For activities authorized  by general permits, decisions are
usually made in less than 30  days. In emergencies, USAGE may be able to
expedite the permitting process  Natural resource managers considering
AIS rapid response actions should contact their District Engineer to discuss
the circumstances and request use of expedited procedures. Expedited
procedures are authorized on a case-by-case basis. Permit applications
that  require the preparation of an Environmental Impact Statement take an
average of 3 years to process

What is the Federal Insecticide, Fungicide, and Rodenticide
Act (FIFRA)?
FIFRA is the principal law that authorizes EPA to regulate thu mdnu!-. i ,
distribution, sale, and use of pesticides in the United States  EPA d.rr--
that a pesticide meets FIFRA health and safety requirements, and the1'
approves a product label that identifies the terms for safe use of the
pesticide. EPA has authority under FIFRA to regulate pesticide use through
labeling, packaging, composition, and disposal. EPA also has authority to
suspend or cancel  pesticide registration if new information shows that
continued use of the pesticide would pose unreasonable risks (For the
complete text of FIFRA, see www.epa.gov/opp00001/regulating/fifra.pdf]

States are also authorized to regulate pesticides under FIFRA and state
pesticide laws. (For the text of Federal regulations regarding state pesticide
registrations, see 40 CFR Part 162 www.access.gpo.gov/nara/cfr/
waisidx_04/40cfr162_04.html] States may place more  restrictive
requirements on pesticides than does  EPA Contact information  for state
pesticide regulatory agencies can be found at http://npic.orst.edu/state1.htm

In particular, FIFRA Sections 18 and 24(c) might apply to AIS rapid response
or control activities  Section 18 applies to use of a pesticide for an
unregistered use, and Section 24(c) applies to new  uses or new  end use
products.
Pesticides are often
understood to be just bug

but they include almost all
substances or mixtures
intended to kill or repel

                        What is FIFRA Section  18?
                        FIFRA Section 18 authorizes EPA to allow states to use a pesticide for
                        an unregistered use for a limited time if EPA determines that emergency
                        conditions exist (For  more information about FIFRA Section  18 emergency

                      When does FIFRA Section 18 apply to AIS rapid response or
                      control actions?
                      AIS rapid response or control methods using pesticides must comply
                      with FIFRA and the regulations promulgated thereunder. If a pesticide is
                      already registered for the rapid response or control use under FIFRA, the
                      action does not require additional permitting from EPA. There are several
                      pesticides registered for use in aquatic environments, and natural resource
                      managers may be able to rely on these pesticides to eradicate or control AIS.
                      If the rapid response or control action requires the use of an unregistered
                      pesticide or a pesticide registered for a different end  use or use pattern
                      and an emergency situation exists, Federal or state agencies may be able
                      to obtain approval to use an unregistered, i e  nonlabeled, pesticide under
                      FIFRA Section 18

                      Emergency exemptions are subject to EPA's regulations at 40 CFR Part 166.
                      A general summary follows

                      An emergency condition is an urgent, nonroutme situation that requires the
                      use of a pesticide or pesticides and meets the following criteria'
                         • no effective registered pesticides are available
                         • no feasible alternative control practices are available
                         • the situation  involves the introduction of a new pest, will cause
                          significant economic loss,  or will present significant risks to human
                          health,  endangered species,  or the  environment

                      Detection of an AIS can qualify as  an emergency condition  Natural resource
                      managers considering use of an unregistered pesticide or a pesticide
                      registered for a different end use or use pattern to eradicate or control AIS
                      should consult their lead state agency for pesticides about the possibility
                      of developing a Section 18 emergency exemption application. Contact

How do I apply for a FIFRA Section 18 Emergency Exemption?
Lead state agencies can develop applications for several categories of
emergency exemptions:
   • specific exemptions are issued to avert significant economic loss
     or a significant risk to endangered or threatened species, beneficial
     organisms, or the environment

   • quarantine exemptions are issued to control the introduction or spread
     of a new or currently localized pest

   • public health exemptions are  issued to control a pest that poses a
     significant risk to human health

   • crisis exemptions are issued in instances when the time between
     discovery of  the emergency and the time when pesticide use is needed
     is insufficient to allow for the authorization of a specific, quarantine, or
     public health exemption

Quarantine exemptions are generally the most appropriate for AIS rapid
response and control actions.  Crisis exemptions may be appropriate when
actions need to be taken extremely quickly (i.e within a matter of days or
weeks).
                                                                           Feathered mosquitofern

Specific, Quarantine, or Public Health Emergency Exemptions
EPA has developed regulations and guidance documents that describe the
data necessary to apply for a Section 18 exemption. A specific, quarantine, or
public health emergency exemption application must provide the following
information'
    1  the type of exemption requested and the identity of contact persons
    2  a description of the pesticide and complete labeling for proposed
       exemption use
    3  a description of the proposed use
    4. alternative methods of control
    5  the effectiveness of the proposed use
    6  residue in food or feed use
    7. a discussion of risk information
    8  coordination with other affected Federal or state agencies
    9  notification of basic manufacturer or registrant
   10  compliance and enforcement program for any special  requirements
   11  repeated uses
   12. progress toward registration, if applicable
Quarantine exemption applications must provide the following  additional
information:
   13  scientific and common name of the pest
   14. origin of the pest and the means of its introduction, if  known
   15. anticipated impact of the pest
   16  impact of the pest  if uncontrolled
   17. pertinent information about the potential economic impacts of
       the pest
EPA attempts to make decisions about the exemption within 50 days  of
receiving a completed application  During this period, EPA conducts dietary,
occupational, and environmental risk assessments of the requested use. EPA
also assesses the emergency situation and the progress toward permanent
pesticide registration for the use in question, if applicable. Some emergency
exemptions require public notification
If EPA determines that the  risks posed by the proposed use of the pesticide
are acceptable and that the criteria for an emergency condition have been
met, EPA approves the emergency exemption request.  If the proposed
Overview of EPA Author/ties for Natural Resource Managers Developing Aquatic Invasive Species Rapid Response and Management Plans

pesticide use may cause unreasonable adverse effects to health or the
environment, or if the emergency exemption criteria are not met, EPA will
deny the emergency exemption request Section 18 emergency exemptions
are typically utilized for pesticides that are already registered under FIFRA
for other uses Quarantine exemptions can be approved for up to 3 years,
whereas other exemptions may only be approved for up to 1 year.

Crisis Exemptions
Crisis exemptions are used in dire situations when an emergency exists, the
time period for pesticide application is critical, and there is insufficient time
to request another type of exemption. A crisis exemption allows for the use
of an unregistered pesticide for up to 15 days If the Federal or state agency
submits or has already submitted an application for a specific, quarantine, or
public health exemption for the same use, use of the unregistered pesticide
under the terms of a crisis exemption  may be allowed to continue until EPA
makes a decision on the exemption application.

A crisis exemption request may be issued by the head of a Federal or
state agency, the Governor of a state, or their official designee  Whenever
feasible, the Federal or state agency issuing the crisis exemption  must notify
EPA of this action at least 36 hours prior to using the crisis provisions. The
notification provided to EPA must contain
     1. the name of the active ingredient and Chemical Abstract Service
       (CAS) number

    2  the site or crop on which  the pesticide is to be used

    3. the use pattern
    4  the approximate start and end date of application
    5  an estimate of the expected pesticide residue level for food  crops

    6  a discussion of the emergency situation and any other pertinent
       information available at the time, including an explanation of why
       there was insufficient time to request another type of exemption

EPA reviews the notification package to ensure that all required information
has been made available and that the  use of the pesticide under the crisis
exemption conditions will not pose an unreasonable risk to health or
the environment  Notification must also be given to the registrant or the
manufacturer of the pesticide. Crisis exemptions may not be utilized for
pesticides that have been suspended  under FIFRA Section 6(c), pesticides
containing a new active ingredient, or the first food use of a pesticide
Neither are they issued to mitigate emergencies for which crisis  exemptions
or specific exemptions have been issued in previous years.

 FIFRA  Section  18  Case  Study:
 Eradicating Northern Snakeheads in
 Crofton,  Maryland Ponds
 On May 18, 2002, a recreational angler caught an 18-inch fish
 in a small pond in Crofton, Maryland, which is located between
 Baltimore, MD and Washington, DC. He photographed the fish
 and released it back into the pond. A month later, the Maryland
 Department of Natural Resources (MD DNR) identified the fish as
 a species of snakehead. In the following two months, a second
 adult snakehead (26 inches long) and over 100 juveniles were
 caught in the same pond and identified as northern snakehead
 Channa argus. Northern snakeheads are large, predatory fish
 native to China. They can grow to 3 feet in length and primarily
 eat other fish, including fish up to one-third their length. They
 can breathe air and survive out of water if kept moist and cool.
 They cannot walk, as is commonly reported, but are easily
 shipped alive or transported by people. MD DNR conducted
 an investigation to determine the source of the snakeheads in
 the Crofton pond and learned that in 2000, a local resident had
 released two 12- to 14-inch northern snakeheads into the pond.

 Immediately after the fish were positively identified and determined to be a risk to local
 ecosystems, the Secretary of the MD DNR (Secretary) assembled the Snakehead Scientific
 Advisory Panel (Panel) to develop strategies for eradicating and controlling the fish in the Crofton
 pond. On July 29, 2002, the Panel presented the Secretary with a list of risks the northern
                                   snakehead posed to natural resources. It recommended
                                   chemical eradication of the Crofton pond vegetation
                                   and fish populations, along with those of two small
                                   adjacent ponds, to prevent the spread of the fish to the
                                   Little Patuxent River. Chemical eradication of vegetation
                                   would remove potential refuges for the fish and facilitate
                                   application of the piscicide rotenone.

                                   The herbicides glyphosate and diquat bromide were
                                   chosen to  eliminate emergent and submerged pond
                                   vegetation. After removal  of the vegetation, application
                                   of the piscicide rotenone would effectively eradicate
 the northern snakeheads in the ponds. These chemicals were chosen for their effectiveness and
 relatively rapid decomposition after application. The Panel recommendation to control vegetation
 in the entire pond area in one application exceeded the manufacturer's label restriction for a
 maximum 50 percent areal application and therefore did not meet Maryland Department of
 Environment (MD DE) standards. Because the proposed diquat bromide application differed from
 allowable use patterns and the available label for diquat bromide, the MD DNR worked with the
 Maryland Department of Agriculture (MD DA), the lead state agency for pesticide registration, to
 submit a FIFRA Section 18 emergency exemption application.

-------
   Quarantine exemptions are generally the most appropriate exemptions for AIS rapid response
   actions requiring Section 18 emergency exemptions. However, the potential for spread of the
   northern snakehead to other water bodies and the potentially devastating environmental impacts
   of such a spread led the MD DNR and MD DA to apply for a crisis exemption because those
   programs can be initiated immediately after the lead state authority declares a crisis situation.
   EPA reviews the crisis on an expedited basis, but use of the pesticide may begin once the lead
   state agency has invoked its authority to initiate a crisis program.

   In the Crofton ponds case, effective interagency collaboration and communication resulted
   in the timely and successful preparation of a Section 18  emergency exemption application.
   The application was prepared by the MD DA Pesticide Coordinator with support from the MD
   DNR and the EPA Section 18 program. MD DA submitted the application package to EPA on
   August 1. The following day, EPA requested confirmation of the pesticide registration number
   (EPA's records showed that two pesticides with the same active ingredient were registered) and
   additional information regarding steps that would be taken to ensure that fish from the treated
   ponds would not be used for human consumption. On August 6, EPA granted a Section 18 crisis
   exemption for the proposed use of diquat bromide in the three Crofton ponds for up to 15 days.

   State  officials faced an additional
   obstacle to herbicide application
   in the Crofton ponds,  however,
   because the ponds were on private
   property and the State lacked the
   statutory authority to access the
   property. Permission to access the
   property was eventually obtained
   from the owners, and the diquat
   bromide was applied before the
   end of the 15-day crisis exemption
   period. After the application of
   herbicides and a piscicide took
   place, over 1000 juvenile and six
   adult northern snakeheads were
   recovered. Approximately 800
   pounds of native fish were also
   removed from the three ponds.

   In late September and November 2002, state biologists used electro-shock monitoring in all three
   ponds and determined that no northern snakeheads remained in the ponds. Vegetation returned
   the following spring, and MD DNR stocked the ponds with native fish. Turtles, frogs, snakes,
   ducks, and beavers appear to have been unaffected by the pesticides.

   In 2004 and 2005, northern snakeheads were found in several other water bodies in the region.
   These fish are believed to be the result of separate introductions rather than the spread of the
   species from the Crofton ponds.

                      FIFRA Section 24(c)—Special  Local Need
                      Registrations

                      What is FIFRA Section 24(c)?
                      FIFRA Section 24(c) authorizes states to register an additional use of a
                      Federally-registered pesticide product or a new end use product to meet a
                      special local need. (For EPA guidance on FIFRA Section 24(c) registrations,
                      see www.epa.gov/opprdOOT/24c.)

                      When does FIFRA Section 24(c) apply to AIS rapid response or
                      control actions?
                      AIS rapid response or control methods using pesticides must comply
                      with FIFRA and the regulations  promulgated thereunder. If a pesticide is
                      already registered for the rapid  response or control use under FIFRA, the
                      action does not require additional permitting from  EPA. There are several
                      pesticides registered for use in  aquatic environments, and natural resource
                      managers may be able to rely on these pesticides  to eradicate or control AIS.
                      If the rapid response or control  action  requires the use of an unregistered
                      pesticide or a pesticide registered for a different end use or use pattern and
                      a state can demonstrate  a special local need, FIFRA Section 24(c) authorizes
                      a state to register an additional  use of a Federally-registered pesticide
                      product.  Section 24(c) registrations are also referred to as state labels or
                      special local need registrations  and are considered Federal registrations
                      authorizing distribution and  use within the granting state only.

State registrations under Section 24(c) are subject to EPA's regulations at 40
CFR Part 162 A general summary follows.

States may register a new use or use pattern of a Federally-registered
pesticide if all of the following conditions exist'
   • There is a special local need for the use within the state A special local
     need is an existing or imminent pest problem within a state for which
     the state has determined that an appropriate Federally-registered
     pesticide is not sufficiently available.
   • If the pesticide use is a food or feed use,  there must exist appropriate
     tolerances (maximum amount of pesticide residue allowed in or on
     a food or feed commodity) or exemptions from the requirement of a
     tolerance under Section 408 of the Federal Food, Drug, and Cosmetic
     Act (FFDCA). If these tolerances do not already exist, a Section 24(c)
     registration cannot be used, and a  Section 18 emergency exemption
     may be more appropriate. Under FFDCA Section 408, EPA may
     establish a temporary tolerance or exemption from the tolerance
     requirement for a Section 18 emergency exemption.
   • Registration for the same use has not previously been denied,
     disapproved, suspended or canceled by EPA, or voluntarily canceled
     by the registrant subsequent to EPA issuing a notice of intent to
     cancel that registration because of health or environmental concerns,
     unless such denial, disapproval, suspension or cancellation has been
     superseded by a subsequent EPA action.

   • The registration is in accord with the purposes of FIFRA.
                                                                                     Nutria

                           How do I apply for a FIFRA Section 24(c) Registration?
                            Each state designs its own review process and timeline for state pesticide
                            registration. As part of its review process, each state is required to conduct
                            an ecological risk assessment (ERA) to determine if the pesticide will cause
                            unreasonable adverse effects on humans or the environment under the
                            following circumstances.
                              •  the pesticide's composition is not similar to any Federally-registered
                                 pesticide

                              •  the use of the pesticide is not similar to any Federally-registered use of
                                 the same pesticide or a pesticide of similar composition

                              •  EPA has denied, disapproved, suspended, or canceled registration
                                 of other uses of the same pesticide or uses of pesticides of similar
                                 composition

                            All products registered by a state must meet all appropriate packaging
                            standards and might need  to be classified as restricted use if their toxicity
                            exceeds EPA specific hazard criteria. Depending on the length of time
                            needed to conduct an ERA, Section 24(c) pesticide  registrations requiring an
                            ERA may be more useful for ongoing control of AIS  rather than for carrying
                            out AIS rapid response actions.

 If a state decides to issue a Section 24(c) registration, it must send EPA a
 notification package within 10 days of issuing a registration containing the
 following:

    •  an application for the Section 24(c) registration

    •  verification of a special local need

    •  if required, a determination  of no unreasonable  adverse effects on
      humans or the environment

    •  verification of efficacy for public health uses

    •  the original registered labeling and the Section 24(c) labeling of the
      pesticide; and

    •  notification of state pesticide registration describing
      - tolerances or clearances  for food or feed use

      - type of registration, i e new pesticide or changed use pattern

      - history of previous Section 24(c) activity or registration for the
        pesticide

      - list of threatened or endangered species within use area of pesticide

 EPA has 90 days to verify that the special local need  registration meets
 FIFRA requirements. If EPA subsequently disapproves the registration,  sales
 and distribution must stop  immediately.

 FIFRA Section 24(c) Case  Study:
 Controlling Old World Climbing Fern  in Florida
 Old World climbing fern Lygodium
 microphyllum is an aggressive
 perennial vine that has invaded
 cypress stands, pineflatwoods,
 wet prairies, sawgrass marshes,
 mangrove communities, and
 Everglade tree islands in Florida.
 The vine can  reach 90 feet in
 length and form dense mats in tree
 canopies, on the ground, and over
 wetlands, killing native vegetation.
 The first reported occurrence of
 Old World climbing fern in Florida
 was a plant in cultivation at a
 Delray Beach nursery in 1958. In
 1960, the vine was observed in the
 wild in Martin County. Old World
 climbing fern eventually became
 a severe threat  to native Florida
 ecosystems, especially cypress-
 dominated wetlands, and in the 1990s, the South Florida Water Management District (SFWMD)
 began evaluating  methods of controlling the vine, including herbicides, fire, flooding, physical
 removal by hand or machinery, and biological controls.

 Aerial spraying  of herbicides is one of the most effective means of controlling invasive plants in
 remote or otherwise  inaccessible areas, but may involve the application of herbicide directly to
 water. Old World  climbing fern had invaded many remote and inaccessible areas in Florida, and
 aerial spraying was desired to control the vine in those areas. At the time, the most effective
 product for controlling the vine registered for direct application to water was the glyphosate-
 based herbicide Rodeo™, a broad spectrum herbicide that injures or kills many nontarget
 species. To avoid harming other vegetation in Old World climbing fern-infested areas, SFWMD
 sought alternatives to Rodeo. The District found that application of the herbicide Escort XP™, a
 metsulfuron methyl-based product, directly to water showed promise as an effective means to
 control the vine. The  application of Escort XP directly to water was not a registered use for the
 product and was therefore not in compliance with FIFRA. To use Escort XP for vine control, the
 SFWMD pursued a Section 24(c) special local need registration for the herbicide.

 Florida natural resource managers wishing to control invasive plants often informally consult
 weed management experts at the University of Florida Institute of Food and  Agricultural Science
 (IFAS) to determine optimal control methods. The SFWMD contacted IFAS about the Old
 World climbing fern, and in April 2003, IFAS informally contacted the DuPont  Corporation, the
 manufacturer of Escort XP, about using the herbicide to control Old World climbing fern in aquatic

                            ecosystems. In Florida, pesticide manufacturers generally begin the
                            Section 24(c) special local need registration process on behalf of
                            natural resource managers who want to use one of their pesticide
                            products for a  new use or use pattern. Consequently, in May 2003,
                            DuPont submitted a Section 24(c) special local need registration
                            application to the Florida Department of Agriculture and Consumer
                            Services (DACS), the lead state agency for pesticide registration.
                            Section 24(c) special local need registration applications in Florida
                            must include verification of the product's efficacy under Florida or
                            Florida-like conditions, as well as the information described in the
                            FIFRA Section 24(c) section of this document.

                            After DACS received the Section 24(c) special  local need registration
                            application, it reviewed the application to verify the special local
                            need justification. In June 2003, DACS forwarded the application
   to the Florida Pesticide Registration Evaluation Committee (PREC), which is comprised of
   representatives from DACS and other state agencies. PREC reviewed the Section 24(c)
   special local need registration application to ensure that the proposed herbicide use would
   not have unreasonable adverse impacts on human health or the Florida environment and was
   in compliance with all applicable pesticide laws. PREC requested that DuPont make several
   revisions to the Escort XP Section 24(c) special  local need label. After these revisions were made,
   the application was submitted to IFAS for independent
   external review of whether product label efficacy
   claims were justified. Three IFAS weed management
   experts  offered individual opinions on the  Escort XP
   efficacy claims. On the basis of these opinions,  IFAS
   responded to DACS that it supported the Section 24(c)
   special local need registration of the herbicide but also
   requested additional changes to the product label.

   In Florida, the Section 24(c) special local need
   registration application review process can take
   anywhere from a few months to over a year. In this
   case, the process was completed quickly.  DACS
   accepted DuPont's Section 24(c) special local need
   registration with the revised label and submitted a
   notification package to EPA in August 2003. EPA also
   requested  revisions to the Escort XP Section 24(c)
   special local need label, including the addition of a
   section prohibiting the use of the herbicide in areas
   where specific endangered or threatened species
   are present. In December 2003,  DACS accepted the
   revised product label. The herbicide is now available
   for controlling Old World climbing fern populations in
   aquatic environments in Florida.
