ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 161

[EPA-HQ-OPP-2004-0387; FRL-8418-5]

Data Requirements for Antimicrobial Pesticides; Technical
Amendment

AGENCY: Environmental Protection Agency (EPA).

ACTION:  Final rule; technical amendment.

-----------------------------------------------------------------------

SUMMARY: EPA is issuing this technical amendment to clarify that the
data requirements for pesticide registration in 40 CFR part 161 are
applicable only to antimicrobial pesticides.

DATES: This technical amendment is effective June 24, 2009.

ADDRESSES: EPA has established a docket for this action under docket
identification (ID) number EPA-HQ-OPP-2004-0387. All documents in the
docket are listed in the docket index available in http://www.regulations.gov. Although listed in the index, some information is
not publicly available, e.g., Confidential Business Information (CBI)
or other information whose disclosure is restricted by statute. Certain
other material, such as copyrighted material, is not placed on the
Internet and will be publicly available only in hard copy form.
Publicly available docket materials are available in the electronic

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this Action Apply to Me?

    The Agency included in the final rule a list of those who may be
potentially affected by this action. If you have questions regarding
the applicability of this action to a particular entity, consult the
person listed under the FOR FURTHER INFORMATION CONTACT.

B. How Can I Access Electronic Copies of this Document and Other
Related Information?

    In addition to accessing electronically available documents at
http://www.regulations.gov, you may access this Federal Register
document electronically through the EPA Internet under the ``Federal
Register'' listings at http://www.epa.gov/fedrgstr.

II. What Does this Technical Amendment Do?

    In the Federal Register of October 24, 2007 (72 FR 60251) (FRL-
8116-2), EPA issued a Final Rule which, among other things,
redesignated 40 CFR part 158 as 40 CFR part 161. The regulations in
redesignated part 161 were intended to apply to, and are applicable
only to antimicrobial pesticides as was shown in the redesignation
table. This technical amendment is issued to clarify the applicability
of part 161, clear up any confusion among the users of the regulations
in 40 CFR parts 158 and 161, and to correct the part heading for part
161 to show applicability to antimicrobial pesticides. The data
requirements for conventional, biochemical, and microbial pesticides
are set forth in 40 CFR part 158.

III. Why is this Tehnical Amendment Issued as a Final Rule?

    Section 553 of the Administrative Procedure Act (APA), 5 U.S.C.
553(b)(B), provides that, when an Agency for good cause finds that
notice and public procedure are impracticable, unnecessary or contrary
to the public interest, the Agency may issue a final rule without
providing notice and an opportunity for public comment. EPA has
determined that there is good cause for making today's technical
amendment final without prior proposal and opportunity for comment,
because EPA is not making any substantive changes to the regulations
and is merely clarifying the applicability of existing regulations to
avoid confusion. EPA finds that this constitutes good cause under 5
U.S.C. 553(b)(B).

IV. Do Any of the Statutory and Executive Order Reviews Apply to this
Action?

    The appropriate statutory and Executive Order reviews were included
in the October 24, 2007 Final Rule.

V. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., generally
provides that before a rule may take effect, the Agency promulgating
the rule must submit a rule report to each House of the Congress and to
the Comptroller General of the United States. EPA will submit a report
containing this rule and other required information to the U.S. Senate,
the U.S. House of Representatives, and the Comptroller General of the
United States prior to publication of this final rule in the Federal
Register. This final rule is not a ``major rule'' as defined by 5
U.S.C. 804(2).

Turfgrass Sod Farms (Submitted in 2006 for 2008 Use Season)

3. Crop and Summary of Crop System  TC "3. Crop and Summary of Crop
System" \f C \l "2"

The Turfgrass Producers International has requested methyl bromide (MB)
as a critical use.

This nomination includes use of MB in the production of turfgrass sod,
grown primarily in California, Florida, Georgia, Alabama, and Texas.
There are at least 1,143 turfgrass sod producers across the U.S. who
farm approximately 132,000 hectares, with a wholesale product value of
U.S. $670 million.  On average, fumigation of the affected soil occurs
once every three years.  Sod fields have been flat fumigated with MB
when first establishing new sod fields and as a pre-plant fumigation
when pest pressures become so severe that effective pest management with
alternatives is particularly difficult.  Turfgrass yields average
between 6,400 and 8,700 square meters per hectare per cutting.  From
planting to harvest, a sod crop takes between 9-12 months to reach
maturity.

"5. Brief Summary of the Need for Methyl Bromide as a Critical Use" \f C
\l "2"

The U. S. nomination is only for those areas where the alternatives are
not effective against key pests when pressure is moderate to high.  The
use of MB is also considered critical only where alternatives are not
suitable because of regulatory, economic, or technical constraints.
Although alternative treatments can be foreseen as long-term solutions
to MB use, transition from MB will depend on the development of
application technologies to better deliver these alternatives to soils
containing target pests.  Alternative treatments may require more
frequent applications and increase costs and environmental pesticide
burden.  Research is ongoing to develop protocols for likely
alternatives.

A small percentage of total hectares for sod farms currently use MB.
The use is primarily for approximately 1% of sod farm hectares that face
pests that are difficult to manage.  The little research that has been
conducted to identify MB alternatives has found that metam-sodium and
dazomet may be acceptable replacements for MB for many farms that
currently use MB.  This sector is still developing methods of
applications that can make these alternatives more effective.

6. Summarize Why Key Alternatives Are Not Feasible  TC "6. Summarize Why
Key Alternatives Are Not Feasible" \f C \l "2"

Primary MeBr alternatives for sod production are metam-sodium and
dazomet, often in combination with chloropicrin and in some cases,
depending on pests, 1,3-D.  Research results (Unruh and Brecke, 2001;
Unruh et al., 2002) suggest that these alternatives have the potential
to be as effective as MB, although research in application technologies
will continue and will permit development of more effective pest control
methodologies.

part of the crop area is treated with methyl bromide, indicate the
reason why methyl bromide is not used in the other area, and identify
what alternative strategies are used to control the target pathogens and
weeds without methyl bromide there." \f C \l "2"

Approximately 1% of the total land planted for turfgrass is treated with
MeBr each year; the affected area averages one treatment every three
years.  MeBr is used only in the portion of the turfgrass area where
pest problems cannot be acceptably controlled using alternative methods.
 For instance, some broadleaf weeds, such as ragweed, pigweed, and
morning glory, may be controlled through continuous mowing to reduce
seed production.  Spot treatment with a nonselective herbicide, such as
glyphosate, may be used to control competitive grasses that can be
easily distinguished from the turfgrass crop.  Relatively low pest
pressures in most of the turfgrass sod production area make it possible
for producers to use alternative pesticides (herbicides, fungicides,
nematicides, and insecticides) and cultural practices.

7. (iii) Would it be feasible to expand the use of these methods to
cover at least part of the crop that has requested use of methyl
bromide?  What changes would be necessary to enable this?  TC "7. (iii)
Would it be feasible to expand the use of these methods to cover at

changes would be necessary to enable this?" \f C \l "2"

Advances in technologies that will improve efficacy (e.g., application
methods, use of VIF) and may increase the area of production where
alternatives can be used effectively.  Research (e.g., Unruh and Brecke,
2001; Unruh et al, 2002) in turfgrass production indicates that fumigant
efficacy (even MB) varies depending on location and pest pressure.  It
is likely that farms where nutsedge is a major pest will have the most
difficult task finding an alternative.

The amount of MeBr nominated by the U.S. was calculated as follows:

Hectares counted in more than one application or rotated within one year
of an application to a crop that also uses MeBr were subtracted.

Growth or increasing production (the amount of area requested by the
applicant that is greater than that historically treated) was
subtracted.  The applicant included growth in the request and the growth

of contamination with off-type perennial grasses, other weeds, pests,
and diseases.  For approximately 1% of the turfgrass sod growing area,
this degree of pest control has been achieved through MeBr fumigation.
However, dazomet and metam sodium with chloropicrin have looked as good
(statistically) and nearly as good (numerically) in control of nutsedge
and weedy grasses as MeBr at the high use rates for turf  (560 kg/ha)
(e.g., Unruh and Brecke, 2001; Unruh et al., 2002).

Chemical Alternatives

Dazomet	Research results indicated that most treatments (including MB)
differed in efficacy depending on site location and specific weed pests
that were evaluated (e.g., Unruh et al., 2002).  In research trials,
dazomet provided poor control of nutsedge in Jay, Florida, 44 weeks
after treatment, compared to MeBr (89% vs. 57%, respectively).  At the
same site, dazomet provided equal control of weedy grasses and slightly
better control of broadleaf weeds compared to MB, 44 weeks after
treatment and 32 weeks after treatment, respectively (Unruh et al.,
2002). MeBr fields may be planted within 48 hours after the plastic
cover is removed, while, depending on soil temperature, a period of 14
to 21 days may be required for effective fumigation when dazomet is used
to treat the soil.

In situations of low pest pressure golfcourses may employ a marginal
strategy without major economic dislocation if given a reasonable time
frame for the transition.	Possibly

1,3-D and 1,3-D + Chloropicrin	Might be used if nematodes are a primary
pest, or possibly in conjunction with dazomet or metam-sodium.  Unruh
and Brecke (2001) did not observe sufficient efficacy for managing weed
pests.	Possibly

Metam-Sodium / Chloropicrin	Unruh and Brecke (2001) found that
metam-sodium with chloropicrin provided comparable control (vs. MB) of
weedy grasses and nutsedge at some locations in Florida but not in all.
Efficacy varied for all treatments, including MB, depending on location.
Possibly

and safety, local environmental regulations) and lack of registration.

Metam-sodium and dazomet, possibly in conjunction with chloropicrin, are
likely effective alternatives to MeBr for turfgrass sod production.
Covering plots treated with metam sodium + chloropicrin with plastic
tarpaulin increased the nutsedge control effectiveness of this
combination in southern Florida, although not in a western Florida site
(Unruh et al., 2002).  However, MeBr was also variable in its efficacy
depending on the location and specific pests.

The turfgrass producers claim that the reduction in MB, for 2003, was a
result of increased use of metam-sodium.  However, they claim a loss of
quality as a result.  Research indicates that metam-sodium and dazomet,
and chloropicrin combinations have the potential to reduce the use of
MeBr in many situations.

Summary of Technical Feasibility  TC "Summary of Technical Feasibility"
\f C \l "2"

Research indicates that metam sodium and dazomet are the best available
alternatives for MeBr in turfgrass sod production.  Metam sodium and
dazomet applied alone, or in conjunction with chloropicrin, can provide
good control of wild and off-type perennial grasses and broad leaf
weeds, but typically, fair to poor control of nutsedge (Unruh and
Brecke, 2001).  In research trials (e.g., Unruh and Brecke, 2001; Unruh
et al., 2002) all of the fumigants that were tested, including MB, had
variable efficacy depending on the location of the field trials.  These
studies indicated that in some locations metam-sodium + chloropicrin,
under polyvinyl tarp, can be as effective as MeBr for controlling some
target weeds.  For areas with nutsedge infestations, efficacy of MeBr
varied depending on location, and was superior in one trial in Florida
and comparable to metam-sodium in another (Unruh et al., 2002).  Farms
with severe nutsedge infestations are most at risk for pest management
problems when using dazomet or metam-sodium.

Summary of Economic Feasibility  TC "Summary of Economic Feasibility" \f
C \l "2"

The primary economic loss that would be expected in sod turfgrass is
price reduction associated with the inability to market sod as
certified, which results in up to a 75% reduction in gross revenue.  The
small proportion of turf production represented by this nomination is
intended for sod growers producing certified sod.

In addition to price reductions from downgraded quality, there are also
expected to be some losses from off-type grasses rendering some areas
simply unharvestable, either from the presence of off-type grasses, or
the required destruction of all grass in a particular area (to prevent
the spreading of off-types).  The losses are much smaller than the
impact of not being able to certify the sod.

The CUE reviewers analyzed crop budgets data for sod turfgrass to
determine the likely economic impact if methyl bromide were not
available. The four economic measures in Table E.1 were used to quantify
the economic impacts to pre-plant uses for sod turfgrass. The four
economic measures are not independent in such a way that they can be
calculated from the same crop budget data. The measures are, however,
supplementary to each other in evaluating the CUE applicant’s economic
viability.  These measures represent different ways to assess the
economic feasibility of methyl bromide alternatives for methyl bromide
users.

Net revenue is calculated as gross revenue minus operating costs.  This
is a good measure as to the direct losses of income that may be suffered
by the users. It should be noted that net revenue does not represent net
income to the users. Net income, which indicates profitability of an
operation of an enterprise, is gross revenue minus the sum of operating
and fixed costs.  Net income should be smaller than the net revenue
measured in this study.  We did not include fixed costs because it is
often difficult to measure and verify.

As stated earlier in the application, the price of non-certified sod is
75% lower than the price of certified sod.  For production areas that
would otherwise fumigate with methyl bromide, it is possible that some
areas will be able to continue producing certified seed for a limited
time, as long as they do not attempt to change variety or species.  But,
as mentioned earlier in the application, changing variety or species is
one primary reason for needed to control off-types of grass.

To reflect a lower bound on impacts, under the assumption that some
areas covered by the nomination would delay their shift in grass type,
or delay their control of other key pests, the economic analysis used
25% as the yield/price effect.  It is important to recognize that in
some areas, the loss could be as high as 75%.  Using the lower bound, we
estimate that a representative grower would suffer $6,634 loss per
hectare per year due to inferior product and a lower proportion of
harvestable acreage, and an increase of fumigation costs with dazomet
(TPI, 2003).  The loss as a percentage of gross revenue was estimated at
33.81% and the loss as a percentage of net revenue at 64.24%. These
changes are estimated to have a significant economic impact to the sod
industry. The results suggest that dazomet is not economically viable as
an alternative for methyl bromide.

Frequency of Treatment – This indicates how often methyl bromide is
applied in the sector.  Frequency varies from multiple times per year to
once in several decades.

Quarantine and Pre-Shipment Removed? – This indicates whether the
Quarantine and pre-shipment (QPS) hectares subject to QPS treatments
were removed from the nomination.

Most Likely Combined Impacts (%) – Adjustments to requested amounts
were factors that reduced to total amount of methyl bromide requested by
factoring in the specific situations were the applicant could use
alternatives to methyl bromide.  These are calculated as proportions of
the total request.  We have tried to make the adjustment to the
requested amounts in the most appropriate category when the adjustment
could fall into more than one category.

(%) Karst geology – Percent karst geology is the proportion of the
land area in a nomination that is characterized by karst formations.  In
these areas, the groundwater can easily become contaminated by
pesticides or their residues.  Regulations are often in place to control
the use of pesticide of concern.  Dade County, Florida, has a ban on the
use of 1,3D due to its karst geology.

(%) 100 ft Buffer Zones – Percentage of the acreage of a field where
certain alternatives to methyl bromide cannot be used due the
requirement that a 100 foot buffer be maintained between the application
site and any inhabited structure.

(%) Key Pest Impacts - Percent (%) of the requested area with moderate
to severe pest problems.  Key pests are those that are not adequately
controlled by MB alternatives.  For example, the key pest in Michigan
peppers, Phytophthora spp. infests approximately 30% of the vegetable
growing area.  In southern states the key pest in peppers is nutsedge.

Regulatory Issues (%) - Regulatory issues (%) is the percent (%) of the
requested area where alternatives cannot be legally used (e.g., township
caps) pursuant to state and local limits on their use.

Unsuitable Terrain (%) – Unsuitable terrain (%) is the percent (%) of
the requested area where alternatives cannot be used due to soil type
(e.g., heavy clay soils may not show adequate performance) or terrain
configuration, such as hilly terrain. Where the use of alternatives
poses application and coverage problems.

Cold Soil Temperatures – Cold soil temperatures is the proportion of
the requested acreage where soil temperatures remain too low to enable
the use of methyl bromide alternatives and still have sufficient time to
produce the normal (one or two) number of crops per season or to allow
harvest sufficiently early to obtain the high prices prevailing in the
local market at the beginning of the season.

Total Combined Impacts (%) - Total combined impacts are the percent (%)
of the requested area where alternatives cannot be used due to key pest,
regulatory, soil impacts, temperature, etc.  In each case the total area
impacted is the conjoined area that is impacted by any individual
impact.  The effects were assumed to be independently distributed unless
contrary evidence was available (e.g., affects are known to be mutually
exclusive).   For example, if 50% of the requested area had moderate to
severe key pest pressure and 50% of the requested area had karst
geology, then 75% of the area was assumed to require methyl bromide
rather than the alternative.  This was calculated as follows: 50%
affected by key pests and an additional 25% (50% of 50%) affected by
karst geology.

Most Likely Baseline Transition – Most Likely Baseline Transition
amount was determined by the DELPHI process and was calculated by
determining the maximum share of industry that can transition to
existing alternatives.

(%) Able to Transition – Maximum share of industry that can transition

Minimum # of Years Required – The minimum number of years required to
achieve maximum transition.

(%) Able to Transition per Year – The Percent Able to Transition per
Year is the percent able to transition divided by the number of years to
achieve maximum transition.

EPA Adjusted Use Rate - Use rate is the lower of requested use rate for
2008 or the historic average use rate or is determined by MBTOC
recommended use rate reductions.

EPA Adjusted Strip Dosage Rate – The dosage rate is the use rate
within the strips for strip / bed fumigation.

2008 Amount of Request – The 2008 amount of request is the actual
amount requested by applicants given in total pounds active ingredient
of methyl bromide, total acres of methyl bromide use, and application
rate in pounds active ingredient of methyl bromide per acre.  U.S. units
of measure were used to describe the initial request and then were
converted to metric units to calculate the amount of the US nomination.

EPA Preliminary Value – The EPA Preliminary Value is the lowest of the
requested amount from 2005 through 2008 with MBTOC accepted adjustments
(where necessary) included in the preliminary value.

EPA Baseline Adjusted Value – The EPA Baseline Adjusted Value has been
adjusted for MBTOC adjustments, QPS, Double Counting, Growth, Use Rate/
Strip Treatment, Miscellaneous adjustments, MBTOC recommended Low
Permeability Film Transition adjustment, and Combined Impacts.

EPA Transition Amount – The EPA Transition Amount is calculated by
removing previous transition amounts since transition was introduced in
2007 and removing the amount of the percent (%) Able to Transition per
Year multiplied by the EPA Baseline Adjusted Value.

Most Likely Impact Value – The qualified amount of the initial request
after all adjustments have been made given in total kilograms of
nomination, total hectares of nomination, and final use rate of
nomination.

Sector Research Amount – The total U.S. amount of methyl bromide
needed for research purposes in each sector.

Total US Sector Nomination - Total U.S. sector nomination is the most
likely estimate of the amount needed in that sector.

Strategy and ARB Board Resolution 04-29 that relate to aggregate
emission reductions in the San Joaquin Valley Air Basin as meeting the
requirements of CAA sections 110(a)(2)(A) and 172(c)(6).
    4. EPA is approving pursuant to CAA section 110(k)(3), the 2004
SIP, the 2003 State Strategy and the 2008 Clarifications as meeting the
RACM (exclusive of RACT) requirements of CAA section 172(c) and 40 CFR
51.905(a)(1)(ii).
    5. EPA is approving pursuant to CAA section 110(k)(3), SJVAPCD Rule
9310 School Bus Fleets (adopted September 21, 2006) into the San
Joaquin Valley portion of the California SIP.

V. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to approve a
SIP submission that complies with the provisions of the Act and
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a).
Thus, in reviewing SIP submissions, EPA's role is to approve State
choices, provided that they meet the criteria of the Clean Air Act.
Accordingly, this action merely approves State law and plans as meeting
Federal requirements and does not impose additional requirements beyond
those imposed by State law. For that reason, this action:
     Is not a ``significant regulatory action'' subject to
review by the Office of Management and Budget under Executive Order
12866 (58 FR 51735, October 4, 1993);
     Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or
uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4);
     Does not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
     Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) because application of those requirements would be inconsistent
with the Clean Air Act; and
     Does not provide EPA with the discretionary authority to
address, as appropriate, disproportionate human health or environmental
effects, using practicable and legally permissible methods, under
Executive Order 12898 (59 FR 7629, February 16, 1994).

In addition, this rule does not have tribal implications as specified
by Executive Order 13175 (65 FR 67249, November 9, 2000), because the
SIP is not approved to apply in Indian country located in the State,
and EPA notes that it will not impose substantial direct costs on
tribal governments or preempt tribal law.
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. EPA will submit a report containing this action and
other required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of the rule in the Federal Register. A major rule cannot
take effect until 60 days after it is published in the Federal
Register. This action is not a ``major rule'' as defined by 5 U.S.C.
804(2).
    Under section 307(b)(1) of the Clean Air Act, petitions for
judicial review of this action must be filed in the United States Court
of Appeals for the appropriate circuit by May 7, 2010. Filing a
petition for reconsideration by the Administrator of this final rule
does not affect the finality of this action for the purposes of
judicial review nor does it extend the time within which a petition for
judicial review may be filed, and shall not postpone the effectiveness
of such rule or action. This action may not be challenged later in
proceedings to enforce its requirements (see section 307(b)(2)).

RIN 2120-AA64

Airworthiness Directives; GROB-WERKE Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for
GROB-WERKE Model G115EG airplanes. This proposed AD results from
mandatory continuing airworthiness information (MCAI) originated by an
aviation authority of another country to identify and correct an unsafe
condition on an aviation product. The MCAI describes the unsafe
condition as cracks in the elevator trim tab arms on several Grob G 115
airplanes, which could result in failure of the part and consequent
loss of control. We are issuing this proposed AD to require actions to
address the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by March 1, 2013.

ADDRESSES: You may send comments by any of the following methods:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued AD
No. 2012-0155, dated August 20, 2012 (referred to after this as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:

    On several Grob G 115 aeroplanes, elevator trim tab arms Part
Number (P/N) 115E-3758 have been found cracked, from a rear mounting
hole (either L/H or R/H) to the rear edge of the trim tab arm.
    This condition, if not detected and corrected, could lead to
further crack propagation, possibly resulting in failure of the part
and consequent loss of control of the aeroplane.
    For the reasons described above, this AD requires repetitive
inspections of the elevator trim tab arm to detect cracks and, if
detected, replacement of the part with a serviceable part.
    This AD also provides an optional terminating action for the
repetitive inspections.

You may obtain further information by examining the MCAI in the AD
docket.

Relevant Service Information

    Grob Aircraft has issued Service Bulletin No. MSB1078-186/3, dated
August 3, 2012. The actions described in this service information are
intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with this State of Design Authority, they
have notified us of the unsafe condition described in the MCAI and
service information referenced above. We are proposing this AD because
we evaluated all information and determined the unsafe condition exists
and is likely to exist or develop on other products of the same type
design.

Costs of Compliance

    We estimate that this proposed AD will affect 0 products of U.S.
registry. We also estimate that it would take about 3 work-hours per
product to comply with the basic requirements of this proposed AD. The
average labor rate is $85 per work-hour. Required parts would cost
about $372 per product.
    Based on these figures, we estimate the cost of the proposed AD on
U.S. operators to be $627 per product.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. ``Subtitle VII: Aviation
Programs,'' describes in more detail the scope of the Agency's
authority.
    We are issuing this rulemaking under the authority described in
``Subtitle VII, Part A, Subpart III, Section 44701: General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.

Regulatory Findings

    We determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would not
have a substantial direct effect on the States, on the relationship
between the national Government and the States, or on the distribution
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed
regulation:
    (1) Is not a ``significant regulatory action'' under Executive
Order 12866,
    (2) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by

The Proposed Amendment

    Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

Grob-Werke: Docket No. FAA-2012-0013; Directorate Identifier 2012-
CE-046-AD.

(a) Comments Due Date

    We must receive comments by March 1, 2013.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to GROB-WERKE G115EG airplanes, all serial
numbers, certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 55: Stabilizers.

(e) Reason

    This AD was prompted by the discovery of cracks in the elevator
trim tab arms on several Grob G 115 airplanes, which could result in
failure of the part and consequent loss of control. We are issuing
this proposed AD to detect cracks and prevent the part from failing.

 (f) Actions and Compliance

    Unless already done, do the following actions following Grob
Aircraft Service Bulletin No. MSB1078-186/3, dated August 3, 2012.
    (1) Within the next 50 hours time-in-service (TIS) after the
effective date of this AD and repetitively thereafter at intervals
not to exceed 200 hours TIS, inspect elevator trim tab arms, part
number (P/N) 115E-3758, using a nondestructive testing (NDT) method
such as a dye-penetrant or eddy-current.

    Note for paragraph (f)(1) of this AD:  There must be a more
significant nondestructive testing (NDT) method of inspection beyond
a visual inspection to accomplish the inspection requirements in
paragraph (f)(1) of this AD.

    (2) If during any inspection required in paragraph (f)(1) of
this AD a crack is found, before further flight, replace the
affected elevator trim tab arm with an airworthy part.

    (3) Replacement at any time of an elevator trim tab arm with an
airworthy part that has a P/N other than P/N 115E-3758, will
terminate the repetitive requirement in paragraph (f)(1) of this AD.

(g) Credit for Actions Accomplished in Accordance With Previous Service
Information

    This AD provides credit for the actions required in this AD if
already done before the effective date of this AD following Grob
Aircraft Service Bulletin No. MSB1078-186/2, dated March 28, 2012;
Grob Aircraft Service Bulletin No. MSB1078-186/1, dated March 8,
2012; or Grob Aircraft Service Bulletin No. MSB1078-186, dated
February 15, 2012.

(h) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager,
Standards Office, FAA, has the authority to approve AMOCs for this
AD, if requested using the procedures found in 14 CFR 39.19. Send
information to ATTN: Taylor Martin, Aerospace Engineer, FAA, Small
Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri
64106; telephone:<PHONE_NUMBER>; fax:<PHONE_NUMBER>; email:

airplane to which the AMOC applies, notify your appropriate
principal inspector (PI) in the FAA Flight Standards District Office
(FSDO), or lacking a PI, your local FSDO.
    (2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
    (3) Reporting Requirements: For any reporting requirement in
this AD, a federal agency may not conduct or sponsor, and a person
is not required to respond to, nor shall a person be subject to a
penalty for failure to comply with a collection of information
subject to the requirements of the Paperwork Reduction Act unless
that collection of information displays a current valid OMB Control
Number. The OMB Control Number for this information collection is
2120-0056. Public reporting for this collection of information is
estimated to be approximately 5 minutes per response, including the
time for reviewing instructions, completing and reviewing the

Approval and Promulgation of Implementation Plans Georgia:
Revisions to State Implementation Plan

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing to approve revisions to the Georgia State
Implementation Plan (SIP), submitted by the Georgia Environmental
Protection Division (GA EPD) in three submittals dated October 31,
2006, March 5, 2007, and August 22, 2007. The submittals include
modifications to Georgia's Rules for Air Quality Control, Chapter 391-
3-1. The October 31, 2006, revision includes changes to ``Permit
Exemption for Combustion Equipment.'' The March 5, 2007, revisions
include changes to ``NOX (Nitrogen Oxides) Emissions from
Electric Utility Steam Generating Units,'' and ``Emission Statements.''
Finally, the August 22, 2007, submittal contains revisions to
``Volatile Organic Compound,'' ``Provisions,'' and ``Stationary
Engines.'' EPA is not acting on the August 22, 2007, revisions to rule
391-3-1-.03(6) ``Exemptions, Combustion Equipment'' in this action. EPA
is also not acting on the August 22, 2007, revisions to rule 391-3-
1-.03(9), as it is not part of the federally-approved SIP. These
submittals included revisions to Georgia's Prevention of Signification
Deterioration and Nonattainment New Source Review programs, which EPA
addressed in a separate action (73 FR 51606). This action is being
taken pursuant to section 110 of the Clean Air Act (CAA).

SUPPLEMENTARY INFORMATION:

I. EPA's Action

    On October 31, 2006, March 5, 2007, and August 22, 2007, GA EPD
submitted proposed SIP revisions to EPA for review and approval into
the Georgia SIP. The rules became state effective on April 19, 2006,
March 12, 2007, and July 25, 2007, respectively. The revisions include
changes made by the State of Georgia to Chapter 391-3-1. Specifically,
the October 31, 2006, revision includes changes to Rule 391-3-
1-.03(6)(b) ``Permit Exemption for Combustion Equipment.'' The March 5,
2007, revisions include changes to Rules 391-3-1-.02(2)(jjj)
``NOX Emissions from Electric Utility Steam Generating
Units,'' and 391-3-1-.02(6)(a)4 ``Emission Statements.'' Finally, the
August 22, 2007, submittal contains revisions to Rules 391-3-
1-.01(llll)

``Volatile Organic Compound,'' 391-3-1-.02 ``Provisions,'' and 391-3-
1-.03(6)(b)11 ``Stationary Engines.'' EPA is now proposing to approve
these revisions. The revisions summarized below are approvable pursuant
to section 110 of the CAA.
    EPA is not acting on the August 22, 2007, revisions to rule 391-3-
1-.03(6) ``Exemptions, Combustion Equipment'' in this action.
Additionally, EPA is not acting on the August 22, 2007, revisions to
rule 391-3-1-.03(9), as it is not part of the federally-approved SIP.

II. Analysis of Georgia's Submittals

October 31, 2006, Submittal

Rule 391-3-1-.03(6)(b), ``Permit Exemption for Combustion Equipment''
    This revision adds two new subparagraphs, (b)14 and 15, for the
purpose of exempting temporary boilers and electric generators that are
used to replace a facility's boilers or generators during periods of
repair or maintenance, from the requirement to obtain a permit. Fuel-
burning equipment that remains at a location for more than 180
consecutive days is no longer considered to be a temporary boiler.
Temporary fuel-burning equipment that replaces temporary equipment at a
location to perform the same function will be included in calculating
the total consecutive time period. This revision provides language
stating the exemption is permissible ``provided the actual and
potential emissions of the temporary sources do not exceed that of the
main source.'' This rule revision is meant to streamline the permitting
process for certain operators, and no longer requires stationary
sources that install temporary boilers and electric generators to
obtain a permit for the temporary equipment operated during periods of
maintenance or repair.

March 5, 2007, Submittal

Rule 391-3-1-.02(2)(jjj), ``NOX Emissions from Electric
Utility Steam Generating Units''
    The revision amends NOX emission limits in subparagraphs
(jjj)4.,5.,6.,7., and 8., for coal-fired electric utility steam
generating units with a maximum heat input greater than 250 Million
British thermal units per hour (MMBtu/hr). The limit is based on a 30-
day rolling average (averaged over all existing units) and was
effective at the beginning of the 2007 ozone season, which runs from
May 1st through September 30th in Georgia. Consistent with the existing
regulation, unit-specific NOX limits are to be established
in a permit. This limit is also included as part of the Macon, Georgia,
8-hour ozone maintenance plan (72 FR 53432).
    Subparagraph 4 specifies that the previous NOX emissions
limit of 0.20 lb/MMBtu was effective through September 30, 2006.
Subparagraph 5, which was effective May 1, 2007, lowers the existing 7-
plant emission limit to 0.18 lb/MMBtu, to account for lower
NOX emissions from Plant Scherer. The requirements of
subparagraphs 4 and 5 apply to all sources located in Bartow, Cherokee,
Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Floyd, Forsyth,
Fulton, Gwinnett, Heard, Henry, Monroe, Paulding, Putnam, and Rockdale
Counties.
    Subparagraph 6 establishes an ozone season NOX emission
limit of 0.17 lb/MMBtu for Georgia Power's Plant Scherer, located in
Monroe County. The requirements in subparagraph 6 apply to sources
located in Monroe County. These revisions also establish an ozone
season NOX emissions limit for Georgia Power's Plant
Scherer, which is located in the Macon area, and also contributes to
ozone levels in the Atlanta nonattainment area.
Rule 391-3-1-.02(6)(a)4, ``Emission Statements''
    The revision amends subparagraph (a)4 to revise the emission
statement requirements to be consistent with the Federal regulations
for 8-hour ozone nonattainment areas. The Emission Statement deadline
is changed from July 31st to June 15th of each calendar year.
Additionally, applicability of the requirements is expanded to include
the counties of Barrow, Bartow, Carroll, Hall, Newton, Spalding and
Walton, which are parts of the Atlanta 8-hour ozone nonattainment area.
The basis of this rule is to require submission of NOX and
volatile organic compounds (VOC) emissions inventories for sources
located in the Atlanta ozone non-attainment area. The purpose of the
revision is to make the rule consistent with current federal
regulations for 8-hour ozone nonattainment areas.

August 22, 2007, Submittal

Rule 391-3-1-.01(llll), ``Volatile Organic Compound''
    The revision submitted by GA EPD adds one compound to the list of
those excluded from the definition of VOC, on the basis that the
compound makes a negligible contribution to ozone formation.
Tropospheric ozone, commonly known as smog, occurs when VOCs and
NOX react in the atmosphere. Because of the harmful health
effects of ozone, EPA limits the amount of VOCs and NOX that
can be released into the atmosphere. VOCs are those compounds of carbon
(excluding carbon monoxide, carbon dioxide, carbonic acid, metallic
carbides, or carbonates, and ammonium carbonate) which form ozone
through atmospheric photochemical reactions. Compounds of carbon (or
organic compounds) have different levels of reactivity; they do not
react at the same speed, or do not form ozone to the same extent.
    It has been EPA's policy that compounds of carbon with a negligible
level of reactivity need not be regulated to reduce ozone (42 FR 35314,
July 8, 1977). EPA determines whether a given carbon compound has
``negligible'' reactivity by comparing the compound's reactivity to the
reactivity of ethane. EPA lists these compounds in its regulations at
40 CFR 51.100(s), and excludes them from the definition of VOC. The
chemicals on this list are often called ``negligibly reactive.'' EPA
may periodically revise the list of negligibly reactive compounds to
add compounds to or delete them from the list. GA EPD's revision
modified the definition of VOC to exclude: 1,1,1,2,2,3,4,5,5,5-
decafluoro-3-methoxy-4-trifluoromethylpentane.
    This revision updates the definition of VOC, to comply with the
Federal list of compounds designated as having negligible photochemical
reactivity.
Rule 391-3-1-.02, ``Provisions''
    GA EPD is revising paragraph (12) ``Clean Air Interstate Rule
NOX Annual Trading Program,'' by deleting inadvertent
references and inserting the correct references in subparagraphs
(f)3(iii), (g)1(i) and (g)1(ii). The rule is being revised to correct
cross-references. Subparagraph (f)3(iii) inadvertently references the
wrong subparagraphs for determining the control period for baseline
heat input for NOX allocations. Revisions to subparagraph
(f)3(iii) updates the reference to subparagraph (f)2(i) and (ii), and
(f)2.(iii) with references to subparagraphs (f)3.(i) and (ii), and
(f)3.(i) through (f)3.(ii), respectively. Subparagraphs (g)1.(i) and
(ii) are amended to be consistent with the changes to subparagraph
(f)3.(iii) above, as well as to add a wording change to clarify the
control period. Specifically, the reference in subparagraph (g)1.(i)
currently stated as ``(f)2. through (f)3.,'' is updated to correctly
read ``(f)1.(i).'' The current reference in (g)1.(ii) to subparagraph
(f)2. through (f)3 is also revised to ``(f)1.(ii).'' Additionally, the
words ``that is four years'' are added to describe the control period
in subparagraph (g)1.(ii).

Rule 391-3-1-.03(6)(b)11, ``Stationary Engines''
    The revision corrects an inadvertent error in subparagraphs (iii)
and (iv) to read ``hours-per-year,'' rather than ``hours-per-hour.''

III. Proposed Action

    EPA is proposing to approve the aforementioned revisions,
specifically, Chapters 391-3-1-.03(6)(b), 391-3-1-.02(2)(jjj), 391-3-
1-.02(6)(a)4, 391-3-1-.01(llll), 391-3-1-.02, and 391-3-1-.03(6)(b)11,
into the Georgia SIP. These revisions were submitted by GA EPD on
October 31, 2006, March 5, 2007, and August 22, 2007.

IV. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP
submission that complies with the provisions of the Act and applicable
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in
reviewing SIP submissions, EPA's role is to approve state choices,
provided that they meet the criteria of the CAA. Accordingly, this
proposed action merely approves state law as meeting Federal
requirements and does not impose additional requirements beyond those
imposed by state law. For that reason, this proposed action:
     Is not a ``significant regulatory action'' subject to
review by the Office of Management and Budget under Executive Order
12866 (58 FR 51735, October 4, 1993);
     Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or
uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4);
     Does not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
     Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) because application of those requirements would be inconsistent
with the CAA; and
     Does not provide EPA with the discretionary authority to
address, as appropriate, disproportionate human health or environmental
effects, using practicable and legally permissible methods, under
Executive Order 12898 (59 FR 7629, February 16, 1994).

In addition, this rule does not have tribal implications as specified
by Executive Order 13175 (65 FR 67249, November 9, 2000), because the
SIP is not approved to apply in Indian country located in the state,
and EPA notes that it will not impose substantial direct costs on
tribal governments or preempt tribal law.
