documentation to the appropriate
council identified in FAR 1.201–1, in
accordance with agency procedures, for
possible addition to the list in FAR
25.104.
1. Proposed Additions to List
Accordingly, the Defense Supply
Center Philadelphia (DSCP), a field
activity of the Defense Logistics Agency
(DLA), has requested addition of yeast
(active dry and instant active dry) and
canned pineapple. The results of DSCP
market research are summarized as
follows:
a. Active Dry Yeast and Instant Active
Dry Yeasts. Through contacts with
industry, reviews of customer
requirements and an analysis of market
availability, DSCP has determined that
there are no domestic sources for active
dry yeast and instant active dry yeast.
All production domestically of active
dry yeast and instant active dry yeast
has ceased with processing shifted to
production facilities in Mexico and
Canada. Active dry yeast and instant
active dry yeast are key ingredients in
the baking of fresh bread and yeastraised products. Contact was made with
DSCP’s customers, and all have stated
that there are no acceptable alternatives
to the active dry yeast and instant active
dry yeast, items that are fundamental in
the preparation of quick breads, white
breads, rolls, variety grain breads,
specialty breads, and yeast-raised
products such as donuts and sweet rolls.
b. Pineapple, Solid Pack, Canned.
There are no longer any domestic
sources for canned pineapple in its
various solid pack forms, including
rings, chunks, tidbits, and crushed. The
last domestic source closed its only
plant in June 2007. Domestic canned
pineapple has been supplanted by
cheaper, imported products. Canned
pineapple is used on the menus of the
U.S. Military Services and as an
ingredient in certain recipes. While it
has been used by the military
worldwide, it is especially important to
customers, such as Navy ships, that
need a longer shelf life item because
they have limited access to fresh fruits.

2. Proposed Revision of List
A previous FAR Case, 2003–007,
added to the list at FAR 25.104(a) an
article titled ‘‘modacrylic fur ruff’’ (69
FR 34241, June 18, 2004). This addition
was based upon a domestic
nonavailability determination approved
by the Under Secretary of Defense
(Acquisition, Technology and Logistics)
dated December 11, 2002, for
modacrylic fiber. Therefore, this rule
proposes to correct the listing to read

3. Publication of List for Comment
Dated: July 22, 2009.
Al Matera,
Director, Office of Acquisition Policy.
In addition, FAR 25.104(b) requires
publication of the list of nonavailable
articles for public comment in the
Federal Register no less frequently than
once every five years. The list was last
published for comment on May 18, 2004
(69 FR 28104) (FAR Case 2004–024).
The Councils are seeking comment on
whether some articles on the list should
be removed because they are now
mined, produced, or manufactured in
the United States in sufficient and
reasonably available commercial
quantities and of a satisfactory quality.
Specific information with regard to
domestic production capacity in
relation to U.S. Government and
nongovernment demand and the quality
of domestically produced items would
be most helpful in determining whether
articles should remain on or be removed
from the list. A sources-sought notice
will also be published in FedBizOpps in
an effort to increase the awareness of
this request.
This is not a significant regulatory
action and, therefore, was not subject to
review under Section 6(b) of Executive
Order 12866, Regulatory Planning and
Review, dated September 30, 1993. This
rule is not a major rule under 5 U.S.C.
804.
B. Regulatory Flexibility Act
The Councils do not expect this
proposed rule to have a significant
economic impact on a substantial
number of small entities within the
meaning of the Regulatory Flexibility
Act, 5 U.S.C. 601, et seq., because the
Councils do not expect that there are
domestic small businesses that can
fulfill the Government’s requirements
for the proposed added items. An Initial
Regulatory Flexibility Analysis has,
therefore, not been performed. We invite
comments from small businesses and
other interested parties. The Councils
will consider comments from small
entities concerning the affected FAR
Part 25 in accordance with 5 U.S.C. 610.
Interested parties must submit such
comments separately and should cite 5
U.S.C. 601, et seq. (FAR case 2009–013),
in correspondence.
C. Paperwork Reduction Act
The Paperwork Reduction Act does
not apply because the proposed changes
to the FAR do not impose information
collection requirements that require the
approval of the Office of Management
and Budget under 44 U.S.C. Chapter 35,
et seq.

SUPPLEMENTARY INFORMATION:
Background
The Migratory Bird Treaty Act of 1918
(Act) (16 U.S.C. 703–711) and the Fish
and Wildlife Improvement Act of 1978
(16 U.S.C. 712) implement migratory
bird treaties between the United States
and Great Britain for Canada (1916,
amended), Mexico (1936, amended),
Japan (1972, amended), and Russia
(then the Soviet Union, 1978). These
treaties protect certain migratory birds
from take, except as permitted under the
Acts. The Acts authorize the Secretary
of the Interior to regulate take of
migratory birds in the United States.
Under this authority, we control
hunting of migratory game birds through
regulations in 50 CFR part 20.
Deposition of toxic shot and release of
toxic shot components in waterfowl
hunting locations are potentially
harmful to many organisms. Research
has shown that ingested spent lead shot
causes significant mortality in migratory
birds. Since the mid-1970s, we have
sought to identify shot types that do not
pose significant toxicity hazards to
migratory birds or other wildlife. We
addressed lead poisoning in waterfowl
in an Environmental Impact Statement
(EIS) in 1976, and again in a 1986
supplemental EIS. The 1986 document
provided the scientific justification for a
ban on the use of lead shot and the
subsequent approval of steel shot for
hunting waterfowl and coots that began
that year, with a complete ban of lead
for waterfowl and coot hunting in 1991.
We have continued to consider other
VerDate Nov<24>2008

Jkt 217001
potential candidates for approval as
nontoxic shot. We are obligated to
review applications for approval of
alternative shot types as nontoxic for
hunting waterfowl and coots.
Tundra Composites, LLC, seeks
approval of Tungsten-IronFluoropolymer (TIF) shot alloys of 41.5
to 95.2 percent tungsten, 1.5 to 52.0
percent steel, and 3.5 to 8.0 percent
fluoropolymer by weight as nontoxic.
The tungsten and iron in this shot type
have already been approved in other
nontoxic shot types. The applicant did
a worst-case evaluation of the potential
impacts of the fluoropolymer on fish,
wildlife, and their habitats.
The data from the applicant indicate
that the tungsten-iron-fluoropolymer
alloys will be nontoxic when ingested
by waterfowl, and should not pose a
significant danger to migratory birds,
other wildlife, or their habitats. We
conclude that they raise no particular
concerns about deposition in the
environment or about ingestion by
waterfowl or predators.
Many hunters believe that some
nontoxic shot types do not compare
favorably to lead and that they may
damage some shotgun barrels, and a
small percentage of hunters have not
complied with nontoxic shot
regulations. Allowing use of additional
nontoxic shot types may encourage
greater hunter compliance and
participation with nontoxic shot
requirements and discourage the use of
lead shot. The use of nontoxic shot for
waterfowl hunting increased after the
ban on lead shot (Anderson et al. 2000),
but we believe that compliance will
continue to increase with the
availability and approval of other
nontoxic shot types. Increased use of
nontoxic shot will enhance protection of
migratory waterfowl and their habitats.
More important, however, is that the
Fish and Wildlife Service is obligated to
consider all complete nontoxic shot
submissions.
We have reviewed the shot under the
criteria in Tier 1 of the revised nontoxic
shot approval procedures contained in
50 CFR 20.134 for permanent approval
of shot as nontoxic for hunting
waterfowl and coots. We propose to
amend 50 CFR 20.21 (j) to add TIF shot
to the list of the approved types of shot
for waterfowl and coot hunting.
Affected Environment
Waterfowl Populations
In 2008, in the Waterfowl Breeding
Population and Habitat Survey
traditional survey area (strata 1–18, 20–
50, and 75–77), the total duck
population estimate was 37.3 ± with a

standard error of 0.6 million birds. This
was 9% lower than last year’s estimate
of 41.2 ± 0.7 million birds, but 11%
above the 1955–2007 long-term average.
Mallard (Anas platyrhynchos)
abundance was 7.7 ± 0.3 million birds,
similar to last year’s estimate of 8.3 ± 0.3
million birds and to the long-term
average. Blue-winged teal (A. discors)
estimated abundance was 6.6 ± 0.3
million birds similar to last year’s
estimate of 6.7 ± 0.4 million birds, and
45% above the long-term average.
Estimated abundances of gadwall (A.
strepera; 2.7 ± 0.2 million) and northern
shovelers (A. clypeata; 3.5 ± 0.2 million)
were lower than those of last year
(¥19% and ¥23%, respectively), but
both remained 56% above their longterm averages. Estimated abundance of
American wigeon (A. americana; 2.5 ±
0.2 million) was similar to the 2007
estimate and the long-term average.
Estimated abundances of green-winged
teal (A. crecca; 3.0 ± 0.2 million) and
redheads (Aythya americana; 1.1 ± 0.1
million) were similar to last year’s, but
were each more than 50% above their
long-term averages. The redhead and
green-winged teal estimates were the
highest and the second highest ever for
the traditional survey area. The
canvasback (A. valisineria) estimate of
0.5 ± 0.05 million was down 44%
relative to 2007’s record high, and 14%
below the long-term average. Northern
pintails (Anas acuta; 2.6 ± 0.1 million)
were 22% below last year’s estimate and
36% below their long-term average. The
estimate for scaup (Aythya affinis and
A. marila combined), 3.7 ± 0.2 million,
was similar to that of 2007 and 27%
below the long-term average.
Habitats
Habitat conditions during the 2008
Waterfowl Breeding Population and
Habitat Survey were characterized in
many areas by a delayed spring
compared to several preceding years.
Drought in many parts of the traditional
survey area contrasted sharply with
record snow and rainfall in the eastern
survey area. The total pond estimate for
Prairie Canada and the United States
combined was 4.4 ± 0.2 million ponds,
37% below last year’s estimate of 7.0 ±
0.3 million ponds and 10% lower than
the long-term average of 4.9 ± 0.03
million ponds. The 2008 estimate of
ponds in Prairie Canada was 3.1 ± 0.1
million. This was a 39% decrease from
last year’s estimate (5.0 ± 0.3 million),
and 11% below the 1955–2007 average
(3.4 ± 0.03 million). The 2008 pond
estimate for the north-central United
States (1.4 ± 0.1 million) was 30% lower
than last year’s estimate (2.0 ± 0.1
million) and 11% below the long-term

average (1.5 ± 0.02 million). The
projected mallard fall-flight index was
9.2 ± 0.8 million, similar to the 2007
estimate of 10.9 ± 1.0 million birds. The
eastern survey area was restratified in
2005 and is now composed of strata 51–
72. Estimates of mallards, scaup, scoters
(black [Melanitta nigra], white-winged
[M. fusca], and surf [M. perspicillata]),
green-winged teal, American wigeon,
bufflehead (B. albeola), American black
duck (A. rubripes), ring-necked duck
(Aythya collaris), mergansers (red-
breasted [Mergus serrator], common [M.
merganser], and hooded [Lophodytes
cucullatus]), and goldeneye (common
[Bucephala clangula] and Barrow’s [B.
islandica]) all were similar to their 2007
estimates and long-term averages.
Characterization of the Shot Type
Tungsten-Iron-Fluoropolymer shot
has a density ranging from 8.0 to 12.5
grams per cubic centimeter (g/cm3), and
is corrosion resistant and magnetic.
Tundra Composites estimates that the
volume of TIF shot for use in hunting
migratory birds in the United States will
be approximately 330,000 pounds
(150,000 kilograms, kg) per year.
The 8.0 g/cm3 alloy is approximately
the same density as steel. The other
alloys are increasingly greater in
sectional density. The steel in the alloys
contains up to 1.3% manganese, 1.2%
silicon, and 1.2% carbon by weight. The
shot may have a very fine residual
coating of mica from production. We
expect the environmental and health
effects of the mica to be negligible.

Environmental Fate of the Tungsten
and Iron in TIF Shot
The tungsten and the iron in these
alloys have been approved in other
nontoxic shot types (see ‘‘Impact of
Approval of the Shot Type’’), and the
submitters asserted that the alloys pose
no adverse toxicological risks to
waterfowl or other forms of terrestrial or
aquatic life. The metals in the alloys are
insoluble under normal hot and cold.
Neither manufacturing the shot nor
firing shotshells containing the shot will
alter the metals or the fluoropolymer, or
change how they dissolve in the
environment.

Possible Environmental Concentrations
for the Manganese and Silicon and
Fluoropolymer in TIF Shot in
Terrestrial Systems
Calculation of the estimated
environmental concentration (EEC) of a
candidate shot in a terrestrial ecosystem
is based on 69,000 shot per hectare (ha)
(50 CFR 20.134). These calculations
assume that the shot dissolves promptly
and completely after deposition.
Because the tungsten and iron have
been approved in other nontoxic shot
types, we focus on the manganese and
silicon in the alloys.
The EEC for the manganese in TIF
shot would be approximately 0.11 parts
per million. The maximum increase in
environmental concentration for
manganese in terrestrial settings would
be 23.1 micrograms per liter. If the shot
were completely dissolved or eroded,
the EEC in soil is much less than the
50th percentile of typical background

concentrations for manganese in soils of
the United States.
If totally dissolved, the shot would
produce a silicon concentration of
0.1082 parts per million (ppm), or 0.07
kg/ha/year. Silicon is not found free in
nature, but combines with oxygen and
other elements in nature to form
silicates (LANL 2003; USGS 2009).
Silicates constitute more than 25% of
the Earth’s crust (USGS 2009). Sand,
quartz, rock crystal, amethyst, agate,
flint, jasper, and opal are some of the
forms in which the oxide appears
(LANL 2003). Thus, the silicon from TIF
shot would be insignificant.
of 100 mg/L as CaCO3). The manganese
from TIF shot would lead to a fraction
of these concentrations, so we believe
that the manganese from TIF shot will
not pose a threat to the environment.
The EEC for silicon from TIF shot
would be 21.4 ppm. The EPA has set no
acute or chronic criteria for silicon in
freshwater or saltwater. Furthermore,
silicates are commonly present in many
soils and sediments.
For the fluoropolymer in the shot, the
EEC in aquatic systems would be 273.1
ppm. We believe this value has little
meaning, given the insolubility of the
fluoropolymer.
Possible Environmental Concentrations
for the Manganese, Silicon, and
Fluoropolymer in the TIF Shot in
Aquatic Systems
The EEC for water assumes that
69,000 number 4 shot are completely
dissolved in 1 ha of water 30.48
centimeters deep. The submitter then
calculates the concentration of each
metal in the shot if the shot pellets
dissolve completely. The analyses
assume complete dissolution of the shot
type containing the highest proportion
of each metal in the range of alloys
submitted.
The maximum EEC for manganese is
23.1 ppm. There are no U.S.
Environmental Protection Agency (EPA)
acute or chronic quality criteria
available for manganese for freshwater
or saltwater. However, the State of
Colorado has acute and chronic
freshwater quality criteria for
manganese of 2,986 ppm and 1,650
ppm, respectively (assuming a hardness
In Vitro Solubility Evaluation of TIF
Shot
When nontoxic shot is ingested by
waterfowl, both physical breakup of the
shot and dissolution of the metals that
comprise the shot may occur in the
highly acidic environment of the
gizzard. In addition to the standard Tier
1 application information (50 CFR
20.134), Tundra Composites provided
the results of an in vitro gizzard
simulation test conducted to quantify
the release of metals in solution under
the prevailing pH conditions of the
avian gizzard. The metal concentrations
released during the simulation test
were, in turn, compared to known levels
of metals that cause toxicity in
waterfowl. The evaluation followed the
methodology of Kimball and Munir
(1971) as closely as possible.
The test solution pH averaged 2.01
over the 14-day test period and the
average temperature of the digestion
solution averaged 41.8 °C. In the test,

the average amount of nickel, copper,
and chromium released from 8 TIF shot/
day was 0.037 mg, 0.017 mg, and 0.024
mg, respectively.
It is reasonable to expect that if the in
vitro gizzard simulation test conditions
had degraded the fluoropolymer in the
TIF shot, fluoride would be present in
the digestion solution. However, the
fluoropolymer present in TIF shot is
extremely resistant to degradation. The
formation of hazardous decomposition
by-products from the fluoropolymer
occurs only at temperatures over 300 °C.
A representative fluoropolymer,
polytetrafluoroethylene, will endure 260
°C for more than 2 years until failure
due to degradation (Imbalzano 1991).
The applicant concluded that the
fluoride concentrations in the solution
were background levels of fluoride in
the digestion solution, rather than a
decomposition by-product of the
fluoropolymer. This conclusion was
supported by the variability and lack of
a trend in the estimated fluoride
concentrations (Day 0 concentrations
were greater than Day 14
concentrations). Perfluorooctanoic acid
(PFOA) is not used in the manufacture
or formulation of the fluoropolymer
present in TIF shot because it has been
identified as a persistent global
contaminant (EPA 2003).
The testing completed by the
applicant indicates that TIF shot is
highly resistant to degradation, and
poses little risk to waterfowl or other
biota if ingested in the field. The slow
breakdown of the shot only permits
metals to be released at concentrations
that are substantially below toxic levels
of concern in waterfowl. Furthermore,
the fluoropolymer present in TIF shot
will not degrade if ingested by
waterfowl.
Impacts of Approval of the Shot Type
pwalker on DSK8KYBLC1PROD with PROPOSALS
Effects of the Metals
We have previously assessed and
approved various alloys containing
tungsten, and/or iron as nontoxic for
hunting waterfowl (e.g. 66 FR 737,
January 4, 2001; 68 FR 1388, January 10,
2003; 69 FR 48163, August 9, 2004; 70
FR 49194, August 23, 2005; and 71 FR
4294, January 26, 2006). We have
approved alloys of almost 100% of both
tungsten and iron. Approval of TIF
alloys raises no new concerns about
approval of the tungsten or the iron in
TIF shot.
Manganese
Manganese is an essential nutrient for
both plants and animals. In animals,
manganese is associated with growth,
normal functioning of the central
VerDate Nov<24>2008

nervous system, and reproductive
function. In plants, manganese is
essential for the oxidation-reduction
process (EPA 2007). Manganese
compounds are important soil
constituents, and the 50th percentile of
typical background concentrations for
manganese range from 400 kg dry
weight in eastern U.S. soils to 600 kg
dry weight in western U.S. soils.
One number 4 TIF shot contains
approximately 0.001 gram of
manganese. The geometric mean of
avian No Observed Adverse Effect Level
(NOAEL) values for reproduction and
growth that were identified by the EPA
in its derivation of an Ecological Soil
Screening Level (Eco-SSL) for
manganese was 179 kg of body weight
per day (EPA 2007). Based upon the
avian NOAEL of 179 milligrams of
manganese per kilogram of body weight
per day, a 2-kg bird could safely
consume about 352 TIF shot per day
without suffering from the consumption
of the shot. Similarly for mammals, the
geometric mean of mammalian NOAEL
values for reproduction and growth that
were identified by the EPA in its
derivation of an Eco-SSL for manganese
was 51.5 milligrams of manganese per
kilogram of body weight per day (EPA
2007). Based upon the mammalian
NOAEL of 51.5 milligrams of manganese
per kilogram of body weight per day, a
1-kg mammal could safely consume
approximately 50 TIF shot per day
without suffering manganese toxicosis.
There are no EPA acute or chronic or
freshwater saltwater criteria for
manganese. However, Colorado acute
and chronic freshwater criteria are 2,986
micrograms per liter and 1,650
micrograms per liter, respectively
(assuming a hardness of 100 milligrams
per liter as CaCO3) (5 CCR 1002–31).
The aquatic EEC for manganese is 23.1
micrograms per liter when we assume
complete dissolution of the 69,000 shot
in 1 ha of water 30.48 cm deep.
Therefore, the manganese from TIF shot
should not pose an environmental
problem in aquatic environments.
Based upon available NOAEL values,
birds and mammals would have to
ingest in excess of 50 TIF shot per day
before manganese toxicosis could occur.
Assuming complete erosion of all shot,
the EEC of manganese in soil is much
less than the 50th percentile of typical
background concentrations for
manganese in soils of the United States.
The EEC for manganese is well below
both the acute and chronic criteria for

exposure concentrations to wetland
biota.
Nickel
No reproductive or other effects were
observed in mallards consuming the
equivalent of 102 milligrams of nickel as
nickel sulfate each day for 90 days
(Eastin and O’Shea 1981). Therefore, the
0.037 milligram of nickel released from
8 TIF shot per day will pose no risk of
adverse effects to waterfowl. In
addition, metallic nickel likely is
absorbed less from the gastrointestinal
tract than is the nickel sulfate used in
the mallard reproduction study.
Copper
The maximum tolerable level of
dietary copper during the long-term
growth of chickens and turkeys has been
reported to be 300 kg (CMTA 1980). At
the maximum tolerable level for chronic
exposure of 300 kg for poultry, a 1.8-kg
chicken consuming 100 g of food per
day (Morck and Austic 1981) would
consume 30 mg copper per day (16.7
milligrams of copper per kilogram of
body weight per day). Since the average
amount of copper released from 8 TIF
shot per day would be 0.017 mg, a bird
would have to ingest in excess of 1000
TIF shot to exceed the maximum
tolerable level.
Dietary levels of 10.0 mg
chromium(III)/kilogram for 10 weeks
depressed survival in young black ducks
(Haseltine et al. 1985), but no adverse
effects were observed in chickens
exposed to 100 ppm dietary
chromium(VI) in a 32-day study
(Rosomer et al. 1961). Therefore, the
average amount of chromium released
from 8 TIF shot/day of 0.024 mg will
pose no risk of adverse effects to
waterfowl.
Effects of Silicon
We found no data for assessing acute
or chronic toxicity of the silicon present
in TIF shot. EPA has not set acute or
chronic criteria for silicon in aquatic
systems. However, silicon compounds
are so widespread in nature, and we
think it highly likely that sediments
consumed incidentally by waterfowl
contain silicates.
Silicon is not found free in nature, but
silicates constitute more than 25% of
the Earth’s crust (USGS 2009), in sand,
quartz, rock crystal, amethyst, agate,
flint, jasper, and opal, among other
rocks. Granite, hornblende, asbestos,
feldspar, clay, and mica are among the
numerous silicate minerals.
Effects of the Fluoropolymer
No data are available on acute or
chronic toxicity of the fluoropolymer

used in the TIF alloys. However,
fluorinated organic polymers are very
stable and resistant to hydrolysis
(Danish Ministry of the Environment
2004). An in vitro gizzard simulation
test conducted with 8.0 g/cm3 TIF shot
showed that the fluoropolymer used in
the alloys will not degrade if ingested by
waterfowl. Exposure to stable
fluoropolymers does not give rise to
increased free fluoride concentration in
the blood in humans (Danish Ministry
of the Environment 2004).
Based on the information provided by
the applicant and our assessment, we
have little concern for problems due to
organisms ingesting TIF shot or from
dissolution of the shot in aquatic
settings.
Effects of the Approval on Migratory
Waterfowl
Allowing use of additional nontoxic
shot types may encourage greater hunter
compliance and participation with
nontoxic shot requirements and
discourage the use of lead shot.
Furnishing additional approved
nontoxic shot types will likely further
reduce the use of lead shot. Thus,
approving additional nontoxic shot
types will likely result in a minor
positive long-term impact on waterfowl
and wetland habitats.
pwalker on DSK8KYBLC1PROD with PROPOSALS
Effects on Endangered and Threatened
Species
The impact on endangered and
threatened species of approval of the
TIF alloys would be very small, but
positive. The metals in TIF alloys have
been approved in other nontoxic shot
types, and we believe that the
fluoropolymer is highly unlikely to
adversely affect animals that consume
the shot or habitats in which the shot
might be used. We see no potential
effects on threatened or endangered
species due to approval of these alloys.
We obtained a biological opinion
pursuant to section 7 of the ESA prior
to establishing the seasonal hunting
regulations. The hunting regulations
promulgated as a result of this
consultation remove and alleviate
chances of conflict between migratory
bird hunting and endangered and
threatened species.
Effects on Ecosystems
Previously approved shot types have
been shown in test results to be
nontoxic to the migratory bird resource,
and we believe that they cause no
adverse impact on ecosystems. There is
concern, however, about noncompliance
and potential ecosystem effects. The use
of lead shot has a negative impact on
wetland ecosystems due to the erosion

of shot, causing sediment/soil and water
contamination and the direct ingestion
of shot by aquatic and predatory
animals. Though we believe
noncompliance is of concern, approval
of the TIF alloys will have little impact
on the resource.
guarantee that we will be able to do so.
We will post all hardcopy comments on
https://www.regulations.gov.
Cumulative Impacts
We foresee no negative cumulative
impacts of approval of the TIF alloys for
waterfowl hunting. Their approval may
help to further reduce the negative
impacts of the use of lead shot for
hunting waterfowl and coots. We
believe the impacts of approval of TIF
shot for waterfowl hunting in the United
States should be positive.
The Office of Management and Budget
(OMB) has determined that this rule is
not significant under E.O. 12866. OMB
bases its determination upon the
following four criteria:
a. Whether the rule will have an
annual effect of $100 million or more on
the economy or adversely affect an
economic sector, productivity, jobs, the
environment, or other units of the
government.
b. Whether the rule will create
inconsistencies with other Federal
agencies’ actions.
c. Whether the rule will materially
affect entitlements, grants, user fees,
loan programs, or the rights and
obligations of their recipients.
d. Whether the rule raises novel legal
or policy issues.
Summary
Previous assessments of nontoxic shot
types indicated that the iron and the
tungsten from shot alloys should not
harm aquatic or terrestrial systems. The
solubility testing of TIF shot indicated
that the negligible release of the metals
from TIF shot (including the trace
amounts of chromium, copper, and
nickel released at low pH) will not be
a hazard to aquatic systems or to biota.
For these reasons, and in accordance
with 50 CFR 20.134, we propose to
approve TIF shot as nontoxic for
hunting waterfowl and coots, and
propose to amend 50 CFR 20.21(j)
accordingly. Our approval is based on
the toxicological report, acute toxicity
studies, reproductive/chronic toxicity
studies, and other published research.
The available information indicates that
the TIF alloys should be nontoxic when
ingested by waterfowl and that they
pose no significant danger to migratory
birds, other wildlife, or their habitats.

Regulatory Flexibility Act (5 U.S.C. 601
et seq.)
Under the Regulatory Flexibility Act
(5 U.S.C. 601 et seq., as amended by the
Small Business Regulatory Enforcement
Fairness Act (SBREFA) of 1996 (Pub. L.
104–121)), whenever an agency is
required to publish a notice of
rulemaking for any proposed or final
rule, it must prepare and make available
for public comment a regulatory
flexibility analysis that describes the
effect of the rule on small entities (i.e.,
small businesses, small organizations,
and small government jurisdictions).
SBREFA amended the Regulatory
Flexibility Act to require Federal
agencies to provide a statement of the
factual basis for certifying that a rule
will not have a significant economic
impact on a substantial number of small
entities. We have examined this rule’s
potential effects on small entities as
required by the Regulatory Flexibility
Act, and have determined that this
action will not have a significant
economic impact on a substantial
number of small entities. The rule
would allow small entities to continue
actions they have been able to take
under the regulations—actions
specifically designed to improve the
economic viability of those entities—
and, therefore, will not significantly
affect them economically. We certify
that because this rule will not have a
significant economic effect on a
substantial number of small entities, a
regulatory flexibility analysis is not
required.

Unfunded Mandates Reform Act
National Environmental Policy Act
Our Draft Environmental Assessment
is part of the administrative record for
this proposed regulations change. In
accordance with the National
Environmental Policy Act (NEPA, 42
U.S.C. 4321 et seq. and Part 516 of the
U.S. Department of the Interior Manual
(516 DM), approval of TIF alloys will
not have a significant effect on the
quality of the human environment, nor
would it involve unresolved conflicts
concerning alternative uses of available
resources. Therefore, preparation of an
Environmental Impact Statement (EIS)
is not required.
In accordance with the Unfunded
Mandates Reform Act (2 U.S.C. 1501 et
seq.), we have determined the following:
a. This rule will not ‘‘significantly or
uniquely’’ affect small governments. A
small government agency plan is not
required. Actions under the regulation
will not affect small government
activities in any significant way.
b. This rule will not produce a
Federal mandate of $100 million or
greater in any year. It will not be a
‘‘significant regulatory action’’ under
the Unfunded Mandates Reform Act.
Takings
In accordance with E.O. 12630, this
rule does not have significant takings
implications. A takings implication
assessment is not required. This rule
does not contain a provision for taking
of private property.
Federalism
This rule does not have sufficient
Federalism effects to warrant
preparation of a Federalism assessment
under E.O. 13132. It will not interfere
with the ability of States to manage
themselves or their funds.
Civil Justice Reform
In accordance with E.O. 12988, the
Office of the Solicitor has determined
that the rule does not unduly burden the
judicial system and meets the
requirements of sections 3(a) and 3(b)(2)
of E.O. 12988.
Government-to-Government
Relationship With Tribes
In accordance with the President’s
memorandum of April 29, 1994,
‘‘Government-to-Government Relations
with Native American Tribal
Governments’’ (59 FR 22951), E.O.
13175, and 512 DM 2, we have
evaluated potential effects on federally
recognized Indian Tribes and have
determined that there are no potential
effects. This rule will not interfere with
the ability of Tribes to manage
themselves or their funds or to regulate
migratory bird activities on Tribal lands.
Energy Supply, Distribution, or Use
(E.O. 13211)
On May 18, 2001, the President issued
E.O. 13211 addressing regulations that
significantly affect energy supply,
distribution, and use. E.O. 13211
requires agencies to prepare Statements
of Energy Effects when undertaking
certain actions. This rule change will
not be a significant regulatory action
under E.O. 12866, nor would it
significantly affect energy supplies,
distribution, or use. This action will not
be a significant energy action, and no
Statement of Energy Effects is required.
Compliance With Endangered Species
Act Requirements
Section 7 of the Endangered Species
Act (ESA) of 1973, as amended (16
U.S.C. 1531 et seq.), requires that ‘‘The
Secretary [of the Interior] shall review
other programs administered by him
and utilize such programs in
furtherance of the purposes of this
chapter’’ (16 U.S.C. 1536(a)(1)). It
further states that the Secretary must
‘‘insure that any action authorized,
funded, or carried out * * * is not
likely to jeopardize the continued
existence of any endangered species or
threatened species or result in the
destruction or adverse modification of
[critical] habitat’’ (16 U.S.C. 1536(a)(2)).
We have concluded that the regulation
change will not affect listed species.

SUPPLEMENTARY INFORMATION:
Background
The Migratory Bird Treaty Act of 1918 (Act) (16 U.S.C. 703-711) and
the Fish and Wildlife Improvement Act of 1978 (16 U.S.C. 712) implement
migratory bird treaties between the United States and Great Britain for
Canada (1916, amended), Mexico (1936, amended), Japan (1972, amended),
and Russia (then the Soviet Union, 1978). These treaties protect
certain migratory birds from take, except as permitted under the Acts.
The Acts authorize the Secretary of the Interior to regulate take of
migratory birds in the United States. Under this authority, we control
hunting of migratory game birds through regulations in 50 CFR part 20.
Deposition of toxic shot and release of toxic shot components in
waterfowl hunting locations are potentially harmful to many organisms.
Research has shown that ingested spent lead shot causes significant
mortality in migratory birds. Since the mid-1970s, we have sought to
identify shot types that do not pose significant toxicity hazards to
migratory birds or other wildlife. We addressed lead poisoning in
waterfowl in an Environmental Impact Statement (EIS) in 1976, and again
in a 1986 supplemental EIS. The 1986 document provided the scientific
justification for a ban on the use of lead shot and the subsequent
approval of steel shot for hunting waterfowl and coots that began that
year, with a complete ban of lead for waterfowl and coot hunting in
1991. We have continued to consider other potential candidates for
approval as nontoxic shot. We are obligated to review applications for
approval of alternative shot types as nontoxic for hunting waterfowl
and coots.
Tundra Composites, LLC, seeks approval of Tungsten-Iron-
Fluoropolymer (TIF) shot alloys of 41.5 to 95.2 percent tungsten, 1.5
to 52.0 percent steel, and 3.5 to 8.0 percent fluoropolymer by weight
as nontoxic. The tungsten and iron in this shot type have already been
approved in other nontoxic shot types. The applicant did a worst-case
evaluation of the potential impacts of the fluoropolymer on fish,
wildlife, and their habitats.
The data from the applicant indicate that the tungsten-iron-
fluoropolymer alloys will be nontoxic when ingested by waterfowl, and
should not pose a significant danger to migratory birds, other
wildlife, or their habitats. We conclude that they raise no particular
concerns about deposition in the environment or about ingestion by
waterfowl or predators.
Many hunters believe that some nontoxic shot types do not compare
favorably to lead and that they may damage some shotgun barrels, and a
small percentage of hunters have not complied with nontoxic shot
regulations. Allowing use of additional nontoxic shot types may
encourage greater hunter compliance and participation with nontoxic
shot requirements and discourage the use of lead shot. The use of
nontoxic shot for waterfowl hunting increased after the ban on lead
shot (Anderson et al. 2000), but we believe that compliance will
continue to increase with the availability and approval of other
nontoxic shot types. Increased use of nontoxic shot will enhance
protection of migratory waterfowl and their habitats. More important,
however, is that the Fish and Wildlife Service is obligated to consider
all complete nontoxic shot submissions.
We have reviewed the shot under the criteria in Tier 1 of the
revised nontoxic shot approval procedures contained in 50 CFR 20.134
for permanent approval of shot as nontoxic for hunting waterfowl and
coots. We propose to amend 50 CFR 20.21 (j) to add TIF shot to the list
of the approved types of shot for waterfowl and coot hunting.
Affected Environment
Waterfowl Populations
In 2008, in the Waterfowl Breeding Population and Habitat Survey
traditional survey area (strata 1-18, 20-50, and 75-77), the total duck
population estimate was 37.3 with a standard error of 0.6
million birds. This was 9% lower than last year's estimate of 41.2
0.7 million birds, but 11% above the 1955-2007 long-term
average. Mallard (Anas platyrhynchos) abundance was 7.7
0.3 million birds, similar to last year's estimate of 8.3
0.3 million birds and to the long-term average. Blue-winged teal (A.
discors) estimated abundance was 6.6 0.3 million birds
similar to last year's estimate of 6.7 0.4 million birds,
and 45% above the long-term average. Estimated abundances of gadwall
(A. strepera; 2.7 0.2 million) and northern shovelers (A.
clypeata; 3.5 0.2 million) were lower than those of last
year (-19% and -23%, respectively), but both remained 56% above their
long-term averages. Estimated abundance of American wigeon (A.
americana; 2.5 0.2 million) was similar to the 2007
estimate and the long-term average. Estimated abundances of green-
winged teal (A. crecca; 3.0 0.2 million) and redheads
(Aythya americana; 1.1 0.1 million) were similar to last
year's, but were each more than 50% above their long-term averages. The
redhead and green-winged teal estimates were the highest and the second
highest ever for the traditional survey area. The canvasback (A.
valisineria) estimate of 0.5 0.05 million was down 44%
relative to 2007's record high, and 14% below the long-term average.
Northern pintails (Anas acuta; 2.6 0.1 million) were 22%
below last year's estimate and 36% below their long-term average. The
estimate for scaup (Aythya affinis and A. marila combined), 3.7 0.2 million, was similar to that of 2007 and 27% below the long-
term average.
Habitats
Habitat conditions during the 2008 Waterfowl Breeding Population
and Habitat Survey were characterized in many areas by a delayed spring
compared to several preceding years. Drought in many parts of the
traditional survey area contrasted sharply with record snow and
rainfall in the eastern survey area. The total pond estimate for
Prairie Canada and the United States combined was 4.4 0.2
million ponds, 37% below last year's estimate of 7.0 0.3
million ponds and 10% lower than the long-term average of 4.9 0.03 million ponds. The 2008 estimate of ponds in Prairie Canada
was 3.1 0.1 million. This was a 39% decrease from last
year's estimate (5.0 0.3 million), and 11% below the 1955-
2007 average (3.4 0.03 million). The 2008 pond estimate
for the north-central United States (1.4 0.1 million) was
30% lower than last year's estimate (2.0 0.1 million) and
11% below the long-term
[[Page 39600]]
average (1.5 0.02 million). The projected mallard fall-
flight index was 9.2 0.8 million, similar to the 2007
estimate of 10.9 1.0 million birds. The eastern survey
area was restratified in 2005 and is now composed of strata 51-72.
Estimates of mallards, scaup, scoters (black [Melanitta nigra], white-
winged [M. fusca], and surf [M. perspicillata]), green-winged teal,

[Mergus serrator], common [M. merganser], and hooded [Lophodytes
cucullatus]), and goldeneye (common [Bucephala clangula] and Barrow's
[B. islandica]) all were similar to their 2007 estimates and long-term
averages.
Characterization of the Shot Type
Tungsten-Iron-Fluoropolymer shot has a density ranging from 8.0 to
12.5 grams per cubic centimeter (g/cm\3\), and is corrosion resistant
and magnetic. Tundra Composites estimates that the volume of TIF shot
for use in hunting migratory birds in the United States will be
approximately 330,000 pounds (150,000 kilograms, kg) per year.
The 8.0 g/cm\3\ alloy is approximately the same density as steel.
The other alloys are increasingly greater in sectional density. The
steel in the alloys contains up to 1.3% manganese, 1.2% silicon, and
1.2% carbon by weight. The shot may have a very fine residual coating
of mica from production. We expect the environmental and health effects
of the mica to be negligible.
Table 1--Composition of TIF Shot Alloys
----------------------------------------------------------------------------------------------------------------
Density (g/ Percent Percent steel Percent

1............................................... 8.0 41.5-50.6 41.6-52.0 6.1-8.0

----------------------------------------------------------------------------------------------------------------
* The steel contains no more than 0.25% chromium, 0.20% copper, and 0.20% nickel. In the alloys, these
percentages are no more than 0.13%, 0.1%, and 0.1%, respectively.
Environmental Fate of the Tungsten and Iron in TIF Shot
The tungsten and the iron in these alloys have been approved in
other nontoxic shot types (see ``Impact of Approval of the Shot
Type''), and the submitters asserted that the alloys pose no adverse
toxicological risks to waterfowl or other forms of terrestrial or
aquatic life. The metals in the alloys are insoluble under normal hot
and cold. Neither manufacturing the shot nor firing shotshells
containing the shot will alter the metals or the fluoropolymer, or
change how they dissolve in the environment.
Possible Environmental Concentrations for the Manganese and Silicon and
Fluoropolymer in TIF Shot in Terrestrial Systems
Calculation of the estimated environmental concentration (EEC) of a
candidate shot in a terrestrial ecosystem is based on 69,000 shot per
hectare (ha) (50 CFR 20.134). These calculations assume that the shot
dissolves promptly and completely after deposition. Because the
tungsten and iron have been approved in other nontoxic shot types, we
focus on the manganese and silicon in the alloys.
The EEC for the manganese in TIF shot would be approximately 0.11
parts per million. The maximum increase in environmental concentration
for manganese in terrestrial settings would be 23.1 micrograms per
liter. If the shot were completely dissolved or eroded, the EEC in soil
is much less than the 50th percentile of typical background
concentrations for manganese in soils of the United States.
If totally dissolved, the shot would produce a silicon
concentration of 0.1082 parts per million (ppm), or 0.07 kg/ha/year.
Silicon is not found free in nature, but combines with oxygen and other
elements in nature to form silicates (LANL 2003; USGS 2009). Silicates
constitute more than 25% of the Earth's crust (USGS 2009). Sand,
quartz, rock crystal, amethyst, agate, flint, jasper, and opal are some
of the forms in which the oxide appears (LANL 2003). Thus, the silicon
from TIF shot would be insignificant.
Possible Environmental Concentrations for the Manganese, Silicon, and
Fluoropolymer in the TIF Shot in Aquatic Systems
The EEC for water assumes that 69,000 number 4 shot are completely
dissolved in 1 ha of water 30.48 centimeters deep. The submitter then
calculates the concentration of each metal in the shot if the shot
pellets dissolve completely. The analyses assume complete dissolution
of the shot type containing the highest proportion of each metal in the
range of alloys submitted.
The maximum EEC for manganese is 23.1 ppm. There are no U.S.
Environmental Protection Agency (EPA) acute or chronic quality criteria
available for manganese for freshwater or saltwater. However, the State
of Colorado has acute and chronic freshwater quality criteria for
manganese of 2,986 ppm and 1,650 ppm, respectively (assuming a hardness
of 100 mg/L as CaCO3). The manganese from TIF shot would
lead to a fraction of these concentrations, so we believe that the
manganese from TIF shot will not pose a threat to the environment.
The EEC for silicon from TIF shot would be 21.4 ppm. The EPA has
set no acute or chronic criteria for silicon in freshwater or
saltwater. Furthermore, silicates are commonly present in many soils
and sediments.
For the fluoropolymer in the shot, the EEC in aquatic systems would
be 273.1 ppm. We believe this value has little meaning, given the
insolubility of the fluoropolymer.
In Vitro Solubility Evaluation of TIF Shot
When nontoxic shot is ingested by waterfowl, both physical breakup
of the shot and dissolution of the metals that comprise the shot may
occur in the highly acidic environment of the gizzard. In addition to
the standard Tier 1 application information (50 CFR 20.134), Tundra
Composites provided the results of an in vitro gizzard simulation test
conducted to quantify the release of metals in solution under the
prevailing pH conditions of the avian gizzard. The metal concentrations
released during the simulation test were, in turn, compared to known
levels of metals that cause toxicity in waterfowl. The evaluation
followed the methodology of Kimball and Munir (1971) as closely as
possible.
The test solution pH averaged 2.01 over the 14-day test period and
the average temperature of the digestion solution averaged 41.8 [deg]C.
In the test,
[[Page 39601]]
the average amount of nickel, copper, and chromium released from 8 TIF
shot/day was 0.037 mg, 0.017 mg, and 0.024 mg, respectively.
It is reasonable to expect that if the in vitro gizzard simulation
test conditions had degraded the fluoropolymer in the TIF shot,
fluoride would be present in the digestion solution. However, the
fluoropolymer present in TIF shot is extremely resistant to
degradation. The formation of hazardous decomposition by-products from
the fluoropolymer occurs only at temperatures over 300 [deg]C. A
representative fluoropolymer, polytetrafluoroethylene, will endure 260
[deg]C for more than 2 years until failure due to degradation
(Imbalzano 1991). The applicant concluded that the fluoride
concentrations in the solution were background levels of fluoride in
the digestion solution, rather than a decomposition by-product of the
fluoropolymer. This conclusion was supported by the variability and
lack of a trend in the estimated fluoride concentrations (Day 0
concentrations were greater than Day 14 concentrations).
Perfluorooctanoic acid (PFOA) is not used in the manufacture or
formulation of the fluoropolymer present in TIF shot because it has
been identified as a persistent global contaminant (EPA 2003).
The testing completed by the applicant indicates that TIF shot is
highly resistant to degradation, and poses little risk to waterfowl or
other biota if ingested in the field. The slow breakdown of the shot
only permits metals to be released at concentrations that are
substantially below toxic levels of concern in waterfowl. Furthermore,
the fluoropolymer present in TIF shot will not degrade if ingested by
waterfowl.
Impacts of Approval of the Shot Type
Effects of the Metals
We have previously assessed and approved various alloys containing
tungsten, and/or iron as nontoxic for hunting waterfowl (e.g. 66 FR
737, January 4, 2001; 68 FR 1388, January 10, 2003; 69 FR 48163, August
9, 2004; 70 FR 49194, August 23, 2005; and 71 FR 4294, January 26,
2006). We have approved alloys of almost 100% of both tungsten and
iron. Approval of TIF alloys raises no new concerns about approval of
the tungsten or the iron in TIF shot.
Manganese
Manganese is an essential nutrient for both plants and animals. In
animals, manganese is associated with growth, normal functioning of the
central nervous system, and reproductive function. In plants, manganese
is essential for the oxidation-reduction process (EPA 2007). Manganese
compounds are important soil constituents, and the 50th percentile of
typical background concentrations for manganese range from 400 kg dry
weight in eastern U.S. soils to 600 kg dry weight in western U.S.
soils.
One number 4 TIF shot contains approximately 0.001 gram of
manganese. The geometric mean of avian No Observed Adverse Effect Level
(NOAEL) values for reproduction and growth that were identified by the
EPA in its derivation of an Ecological Soil Screening Level (Eco-SSL)
for manganese was 179 kg of body weight per day (EPA 2007). Based upon
the avian NOAEL of 179 milligrams of manganese per kilogram of body
weight per day, a 2-kg bird could safely consume about 352 TIF shot per
day without suffering from the consumption of the shot. Similarly for
mammals, the geometric mean of mammalian NOAEL values for reproduction
and growth that were identified by the EPA in its derivation of an Eco-
SSL for manganese was 51.5 milligrams of manganese per kilogram of body
weight per day (EPA 2007). Based upon the mammalian NOAEL of 51.5
milligrams of manganese per kilogram of body weight per day, a 1-kg
mammal could safely consume approximately 50 TIF shot per day without
suffering manganese toxicosis.
There are no EPA acute or chronic or freshwater saltwater criteria
for manganese. However, Colorado acute and chronic freshwater criteria
are 2,986 micrograms per liter and 1,650 micrograms per liter,
respectively (assuming a hardness of 100 milligrams per liter as
CaCO3) (5 CCR 1002-31). The aquatic EEC for manganese is
23.1 micrograms per liter when we assume complete dissolution of the
69,000 shot in 1 ha of water 30.48 cm deep. Therefore, the manganese
from TIF shot should not pose an environmental problem in aquatic
environments.
Based upon available NOAEL values, birds and mammals would have to
ingest in excess of 50 TIF shot per day before manganese toxicosis
could occur. Assuming complete erosion of all shot, the EEC of
manganese in soil is much less than the 50th percentile of typical
background concentrations for manganese in soils of the United States.
The EEC for manganese is well below both the acute and chronic criteria
for freshwater from the State of Colorado, assuming complete
dissolution of the shot. In sum, the manganese in TIF shot will result
in very minimal estimated exposure concentrations to wetland biota.
Nickel
No reproductive or other effects were observed in mallards
consuming the equivalent of 102 milligrams of nickel as nickel sulfate
each day for 90 days (Eastin and O'Shea 1981). Therefore, the 0.037
milligram of nickel released from 8 TIF shot per day will pose no risk
of adverse effects to waterfowl. In addition, metallic nickel likely is
absorbed less from the gastrointestinal tract than is the nickel
sulfate used in the mallard reproduction study.
Copper
The maximum tolerable level of dietary copper during the long-term
growth of chickens and turkeys has been reported to be 300 kg (CMTA
1980). At the maximum tolerable level for chronic exposure of 300 kg
for poultry, a 1.8-kg chicken consuming 100 g of food per day (Morck
and Austic 1981) would consume 30 mg copper per day (16.7 milligrams of
copper per kilogram of body weight per day). Since the average amount
of copper released from 8 TIF shot per day would be 0.017 mg, a bird
would have to ingest in excess of 1000 TIF shot to exceed the maximum
tolerable level.
Dietary levels of 10.0 mg chromium(III)/kilogram for 10 weeks
depressed survival in young black ducks (Haseltine et al. 1985), but no
adverse effects were observed in chickens exposed to 100 ppm dietary
chromium(VI) in a 32-day study (Rosomer et al. 1961). Therefore, the
average amount of chromium released from 8 TIF shot/day of 0.024 mg
will pose no risk of adverse effects to waterfowl.
Effects of Silicon
We found no data for assessing acute or chronic toxicity of the
silicon present in TIF shot. EPA has not set acute or chronic criteria
for silicon in aquatic systems. However, silicon compounds are so
widespread in nature, and we think it highly likely that sediments
consumed incidentally by waterfowl contain silicates.
Silicon is not found free in nature, but silicates constitute more
than 25% of the Earth's crust (USGS 2009), in sand, quartz, rock
crystal, amethyst, agate, flint, jasper, and opal, among other rocks.
Granite, hornblende, asbestos, feldspar, clay, and mica are among the
numerous silicate minerals.
Effects of the Fluoropolymer
No data are available on acute or chronic toxicity of the
fluoropolymer
[[Page 39602]]
used in the TIF alloys. However, fluorinated organic polymers are very
stable and resistant to hydrolysis (Danish Ministry of the Environment
2004). An in vitro gizzard simulation test conducted with 8.0 g/cm\3\
TIF shot showed that the fluoropolymer used in the alloys will not
degrade if ingested by waterfowl. Exposure to stable fluoropolymers
does not give rise to increased free fluoride concentration in the
blood in humans (Danish Ministry of the Environment 2004).
Based on the information provided by the applicant and our
assessment, we have little concern for problems due to organisms
ingesting TIF shot or from dissolution of the shot in aquatic settings.
Effects of the Approval on Migratory Waterfowl
Allowing use of additional nontoxic shot types may encourage
greater hunter compliance and participation with nontoxic shot
requirements and discourage the use of lead shot. Furnishing additional
approved nontoxic shot types will likely further reduce the use of lead
shot. Thus, approving additional nontoxic shot types will likely result
in a minor positive long-term impact on waterfowl and wetland habitats.
Effects on Endangered and Threatened Species
The impact on endangered and threatened species of approval of the
TIF alloys would be very small, but positive. The metals in TIF alloys
have been approved in other nontoxic shot types, and we believe that
the fluoropolymer is highly unlikely to adversely affect animals that
consume the shot or habitats in which the shot might be used. We see no
potential effects on threatened or endangered species due to approval
of these alloys.
We obtained a biological opinion pursuant to section 7 of the ESA
prior to establishing the seasonal hunting regulations. The hunting
regulations promulgated as a result of this consultation remove and
alleviate chances of conflict between migratory bird hunting and
endangered and threatened species.
Effects on Ecosystems
Previously approved shot types have been shown in test results to
be nontoxic to the migratory bird resource, and we believe that they
cause no adverse impact on ecosystems. There is concern, however, about
noncompliance and potential ecosystem effects. The use of lead shot has
a negative impact on wetland ecosystems due to the erosion of shot,
causing sediment/soil and water contamination and the direct ingestion
of shot by aquatic and predatory animals. Though we believe
noncompliance is of concern, approval of the TIF alloys will have
little impact on the resource.
Cumulative Impacts
We foresee no negative cumulative impacts of approval of the TIF
alloys for waterfowl hunting. Their approval may help to further reduce
the negative impacts of the use of lead shot for hunting waterfowl and
coots. We believe the impacts of approval of TIF shot for waterfowl
hunting in the United States should be positive.
Summary
Previous assessments of nontoxic shot types indicated that the iron
and the tungsten from shot alloys should not harm aquatic or
terrestrial systems. The solubility testing of TIF shot indicated that
the negligible release of the metals from TIF shot (including the trace
amounts of chromium, copper, and nickel released at low pH) will not be
a hazard to aquatic systems or to biota. For these reasons, and in
accordance with 50 CFR 20.134, we propose to approve TIF shot as
nontoxic for hunting waterfowl and coots, and propose to amend 50 CFR
20.21(j) accordingly. Our approval is based on the toxicological
report, acute toxicity studies, reproductive/chronic toxicity studies,
and other published research. The available information indicates that
the TIF alloys should be nontoxic when ingested by waterfowl and that
they pose no significant danger to migratory birds, other wildlife, or
their habitats.

Required Determinations
Regulatory Planning and Review (E.O. 12866)
The Office of Management and Budget (OMB) has determined that this
rule is not significant under E.O. 12866. OMB bases its determination
upon the following four criteria:
a. Whether the rule will have an annual effect of $100 million or
more on the economy or adversely affect an economic sector,
productivity, jobs, the environment, or other units of the government.
b. Whether the rule will create inconsistencies with other Federal
agencies' actions.
c. Whether the rule will materially affect entitlements, grants,
user fees, loan programs, or the rights and obligations of their
recipients.
d. Whether the rule raises novel legal or policy issues.
Regulatory Flexibility Act (5 U.S.C. 601 et seq.)
Under the Regulatory Flexibility Act (5 U.S.C. 601 et seq., as
amended by the Small Business Regulatory Enforcement Fairness Act
(SBREFA) of 1996 (Pub. L. 104-121)), whenever an agency is required to
publish a notice of rulemaking for any proposed or final rule, it must
prepare and make available for public comment a regulatory flexibility
analysis that describes the effect of the rule on small entities (i.e.,
small businesses, small organizations, and small government
jurisdictions).
SBREFA amended the Regulatory Flexibility Act to require Federal
agencies to provide a statement of the factual basis for certifying
that a rule will not have a significant economic impact on a
substantial number of small entities. We have examined this rule's
potential effects on small entities as required by the Regulatory
Flexibility Act, and have determined that this action will not have a
significant economic impact on a substantial number of small entities.
The rule would allow small entities to continue actions they have been
able to take under the regulations--actions specifically designed to
improve the economic viability of those entities--and, therefore, will
not significantly affect them economically. We certify that because
this rule will not have a significant economic effect on a substantial
number of small entities, a regulatory flexibility analysis is not
required.
[[Page 39603]]
This rule is not a major rule under the SBREFA (5 U.S.C. 804(2)).
a. This rule will not have an annual effect on the economy of $100
million or more.
b. This rule will not cause a major increase in costs or prices for
consumers; individual industries; Federal, State, Tribal, or local
government agencies; or geographic regions.
c. This rule will not have significant adverse effects on
competition, employment, investment, productivity, innovation, or the
ability of U.S.-based enterprises to compete with foreign-based
enterprises.
Unfunded Mandates Reform Act
In accordance with the Unfunded Mandates Reform Act (2 U.S.C. 1501
et seq.), we have determined the following:
a. This rule will not ``significantly or uniquely'' affect small
governments. A small government agency plan is not required. Actions
under the regulation will not affect small government activities in any
significant way.
b. This rule will not produce a Federal mandate of $100 million or
greater in any year. It will not be a ``significant regulatory action''
under the Unfunded Mandates Reform Act.
Takings
In accordance with E.O. 12630, this rule does not have significant
takings implications. A takings implication assessment is not required.
This rule does not contain a provision for taking of private property.
Federalism
This rule does not have sufficient Federalism effects to warrant
preparation of a Federalism assessment under E.O. 13132. It will not
interfere with the ability of States to manage themselves or their
funds.
Civil Justice Reform
In accordance with E.O. 12988, the Office of the Solicitor has
determined that the rule does not unduly burden the judicial system and
meets the requirements of sections 3(a) and 3(b)(2) of E.O. 12988.
Paperwork Reduction Act
This proposed rule does not contain any new collections of
information that require approval by the Office of Management and
Budget (OMB) under the Paperwork Reduction Act (44 U.S.C. 3501 et
seq.). An agency may not conduct or sponsor and a person is not
required to respond to a collection of information unless it displays a
currently valid OMB control number. OMB has approved our collection of
information associated with applications for approval of nontoxic shot
(50 CFR 20.134) and assigned OMB Control Number 1018-0067, which
expires April 30, 2012.
National Environmental Policy Act
Our Draft Environmental Assessment is part of the administrative
record for this proposed regulations change. In accordance with the
National Environmental Policy Act (NEPA, 42 U.S.C. 4321 et seq. and
Part 516 of the U.S. Department of the Interior Manual (516 DM),
approval of TIF alloys will not have a significant effect on the
quality of the human environment, nor would it involve unresolved
conflicts concerning alternative uses of available resources.
Therefore, preparation of an Environmental Impact Statement (EIS) is
not required.
Government-to-Government Relationship With Tribes
In accordance with the President's memorandum of April 29, 1994,
``Government-to-Government Relations with Native American Tribal
Governments'' (59 FR 22951), E.O. 13175, and 512 DM 2, we have
evaluated potential effects on federally recognized Indian Tribes and
have determined that there are no potential effects. This rule will not
interfere with the ability of Tribes to manage themselves or their
funds or to regulate migratory bird activities on Tribal lands.
Energy Supply, Distribution, or Use (E.O. 13211)
On May 18, 2001, the President issued E.O. 13211 addressing
regulations that significantly affect energy supply, distribution, and
use. E.O. 13211 requires agencies to prepare Statements of Energy
Effects when undertaking certain actions. This rule change will not be
a significant regulatory action under E.O. 12866, nor would it
significantly affect energy supplies, distribution, or use. This action
will not be a significant energy action, and no Statement of Energy
Effects is required.
Compliance With Endangered Species Act Requirements
Section 7 of the Endangered Species Act (ESA) of 1973, as amended
(16 U.S.C. 1531 et seq.), requires that ``The Secretary [of the
Interior] shall review other programs administered by him and utilize
such programs in furtherance of the purposes of this chapter'' (16
U.S.C. 1536(a)(1)). It further states that the Secretary must ``insure
that any action authorized, funded, or carried out * * * is not likely
to jeopardize the continued existence of any endangered species or
threatened species or result in the destruction or adverse modification
of [critical] habitat'' (16 U.S.C. 1536(a)(2)). We have concluded that
the regulation change will not affect listed species.
