This memo provides the revised estimated drinking water concentrations from surface water for assisting the Health and Effects Division in determining the potential risk to human health. This is the revision of the drinking water memo dated June 29, 2006.

Use Information The active ingredient propiconazole is a triazole fungicide that has protective, curative, and systemic activity. Some trade names for products containing propiconazole include Banner, Benit, Desmel, Orbit, Radar, Tilt, Fidis, Alamo, Spire, Practis, Bumper, Mantis, Restore, Banner Maxx, Taspa, Juno, Novel and Break. Formulations include emulsifiable concentrates and wettable powders. It is also formulated with other pesticides. The use practices actually simulated for this assessment are presented in the Table 1. 2 Table 1  Application practices simulated for propiconazole drinking water assessment Use Rate Annual Rate Interval Method* Agricultural Use Wheat 0.1125 ( lb ai/ ac) 0.225 ( lb ai/ ac) 14 ( days) G, C, A Seed Crops ( Grasses) 0.225 0.90 14 G, C, A Rice 0.17 0.34 10 A Pecans 0.225 0.90 14 G, A Peaches 0.1125 0.56 5 G, A Sweet Corn 0.1125 0.45 7 G, C, A Dry Beans 0.1125 0.3375 14 G, C, A Peanuts 0.225 0.45 10 G, C, A Barley 0.1125 0.1125 NA G, C, A Celery 0.1125 0.45 7 G, C, A Non Agricultural Use Turf and Ornamentals   Lawn and Turf, Golf Course 1.78 7.2 14 G, C Ground Cover 1.78 7.2 10 G, C Sod Farm 1.78 7.2 21 G, C * G = Ground spray; C = Chemigation ( w/ irrigation); A = Aerial spray.

Monitoring Data A registrant submitted monitoring study, " Monitoring of Propiconazole ( CGA 64250) Residues in Surface Water at Selected US Community Water Systems," showed few detections among a total of thirty eight selected CWSs located in twelve states ( California, Florida, Georgia, Iowa, Illinois, Indiana, North Dakota, New Jersey, Oregon, Texas, Washington, and Wisconsin). The study design assumed that detections would be expected during the propiconazole use months, therefore the sampling frequency was two samples during the use months and one sample for the remaining months. The highest detection was reported during the non use months. These results suggest that the sampling scheme of only 18 samples per year has missed possible higher residue detections. Therefore, EFED concluded that the sampling scheduling of this monitoring study is not rigid enough to be used for drinking water assessment ( March 26, 2006, DP325258). Since the monitoring studies did not provide good quality data, this drinking water assessment is based on the model predicted drinking water concentrations.

Models, Scenarios, and Input Parameters Used To Estimate Concentrations of Propiconazole With the exception of rice use, estimated drinking water concentrations from surface water sources were calculated using Tier II PRZM ( Pesticide Root Zone Model) and EXAMS ( Exposure Analysis Modeling System). PRZM is used to simulate pesticide transport as a result 3 of runoff, erosion, and off target spray drift from an agricultural field and EXAMS estimates environmental fate and transport of pesticides in surface water. These models are run using the linkage program shell, PE4V01, which incorporates the standard scenarios developed by EFED.

Linked crop specific scenarios and meteorological data were used to estimate exposure as a result of uses on various field crops and vegetables. Simulations were done using the Index Reservoir scenario in EXAMS, which is designed after an actual reservoir for a drinking water source drawn from surface water. Weather and agricultural practices are simulated over 30 years so that the 1 in10 year exceedence probability at the site can be estimated. The values generated by the models for drinking water were multiplied by a crop area factor ( PCA), which represents the maximum extent to which HUC 8 watersheds in the continental US are planted to agricultural. crops.

For further information on these models use the following web link  http:// www. epa. gov/ oppefed1/ models/ water/ index. htm Rice Use The Policy for Estimating Aqueous Concentrations from Pesticides Labeled for Use on Rice, dated October 29, 2002, was followed in estimating drinking water concentrations from rice use. The estimated environmental concentration ( EEC in ug/ L) represents the dissolved concentration occurring in the water column and the concentration in water released from the paddy. Movement of pesticide on suspended sediment is not considered. The equation to use for this calculation is:

EEC M V m K T T sed d = + 109 where MT is the total mass of pesticide in kg applied per ha of paddy, VT is 1.067 x106 L/ ha which is the volume of water in a paddy 4 inches ( 10.16 cm) deep, and includes the pore space in a 1 cm sediment interaction zone. The mass of sediment, msed, is the amount found in the top 1 cm interaction zone and is 130,000 kg/ ha when the sediment bulk density is assumed to be 1.3 kg/ L, a standard assumption for the bulk density of surface horizons of mineral soils. The 109 constant converts the units of mass from kg to ug. For chemicals that have a valid Koc, the Kd can be calculated using a sediment carbon content of 2% ( Koc* 0.02). An organic carbon content of 2% represents a typical value for a high clay soil that might be used to grow rice in the Mississippi River Valley or gulf coast regions.

The above equation calculates the concentration of rice paddy water with adsorption and dilution. Since propiconazole degrades quickly in the rice paddy environment with a half life of 5 days, which is equivalent to a first order degradation rate of 0. l39/ day, to further simulate the propiconaozle concentrations in the rice paddy, this degradation needs to be taken into consideration. This degradation rate was used in simulating the continuing degradation in the rice paddy environment. 4 Surface water Several of EFED's standard scenarios were simulated for this drinking water assessment. These scenarios are briefly identified in Table 2. For each specific use, drinking water concentrations were estimated assuming the maximum allowable label rate. The final estimated drinking water concentrations were then adjusted with the proper PCA, The default PCA of 0.87 was used . except for the uses on sweet corn ( 0.46) and wheat ( 0.56). There is no PCA correction for rice use.

Drinking Water Estimates from Surface Water Sources The estimated drinking water concentrations of propiconazole both pre and post PCA in surface water are summarized in Table 3. In general, the higher use rate produces the higher drinking water concentrations. In addition, the PCA also plays a big adjustment factor. Except corn ( sweet corn: 0.46) and wheat ( 0.56), other crop uses the default value of 0.87.

Rice use results in the highest peak ( acute) drinking water concentration ( 86.49 ug/ L) among all assessed uses. For chronic concerns, due to rapid degradation in the rice paddy environment ( half life of 5 days), the estimated annual mean concentration is 2.92 ug/ L. No PCA adjustment is needed for this use, since these concentrations represent residues from paddy discharge water. These results are considered as upper bounds of the drinking water concentrations from rice use.

After rice, the turf use results in the second highest acute drinking water concentrations. The acute values are 76.5 and 65.3 ug/ L, respectively for PA and FL turf scenario. The chronic values are 37.5 and 26.5 ug/ L, respectively. The high values are the results of high application rate ( up to 7.2 lb ai/ ac per year). Among other uses, only pecans use ( 17.0 ug/ L) and celery use ( 11.9 ug/ L) are greater than 10 ug/ L for acute concern. For chronic concern, except turf uses, none of the other uses have values greater than 5.0 ug/ L. 6 Table 3   Estimated Drinking Water Concentrations from Surface Water Sources Pre PAC Adjustment Post PCA Adjustment Use Scenario 1 in 10 probability peak ( Acute) 1 in 10 probability yearly ( Chronic) 1 in 10 probability peak ( Acute) 1 in 10 probability yearly ( Chronic)

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for
Airbus Helicopters Model MBB-BK 117 C-2 helicopters with certain duplex
trim actuators installed. This proposed AD would require repetitively
inspecting the lateral and longitudinal trim actuator output levers for
correct torque of the nuts. This proposed AD is prompted by a design
review that the attachment screws can become lost under certain
circumstances. The proposed actions are intended to prevent the loss of
an attachment screw, which could result in movement of the output lever
in an axial direction, contact of a bolt connecting the control rod to
an output lever with the actuator housing, and subsequent loss of
helicopter control.

DATES: We must receive comments on this proposed AD by October 17,
2014.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Docket: Go to http://www.regulations.gov. Follow the online instructions for sending your

Discussion

    EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD No. 2013-0182, dated August 12,
2013, to correct an unsafe condition for Airbus Helicopters Model MBB-
BK 117 C-2 helicopters with a lateral duplex trim actuator, part number
(P/N) 418-00878-050 or P/N 418-00878-051, or with a longitudinal duplex
trim actuator, P/N 418-00878-000 or P/N 418-00878-001. EASA advises
that recent analysis has shown that under unfavorable circumstances, a
total loss of the trim actuator output lever attachment screw could
lead to a restriction of the lateral and longitudinal control range.
According to EASA, without the attachment screw, the output lever can
move in the axial direction. This condition, if not detected, could
cause the bolt that connects the control rod to the output lever to
make contact with actuator housing, possibly resulting in reduced
control of the helicopter. To prevent this condition, EASA requires an
initial torque check of the lateral and longitudinal trim actuator
output level attachment screws, the application of a torque marking,
and repetitive inspections for correct torque thereafter. The AD's
requirements are considered an interim solution, pending a terminating
modification.
    Since the issuance of EASA AD No. 2013-0182, Eurocopter Deutschland
GmbH has changed its name to Airbus Helicopters Deutschland GmbH.

 FAA's Determination

    These helicopters have been approved by the aviation authority of
Germany and are approved for operation in the United States. Pursuant
to our bilateral agreement with Germany, EASA, its technical
representative, has notified us of the unsafe condition described in
its AD. We are proposing this AD because we evaluated all known
relevant information and determined that an unsafe condition is likely
to exist or develop on other products of the same type design.

Related Service Information

    We reviewed Eurocopter (now Airbus Helicopters) Alert Service
Bulletin MBB-BK117 C-2-67A-020, Revision 0, dated June 18, 2013 (ASB),
which advises of a design review that showed that a loss of the
attachment screw of the trim actuator output lever could restrict the
lateral and longitudinal control range. The ASB consequently calls for
an initial torque check and application of torque markings of the self-
locking nuts, and subsequent repetitive inspections to maintain the
proper torque.

Proposed AD Requirements

    This proposed AD would require, within 300 hours time-in-service
(TIS) and thereafter at intervals not exceeding 400 hours TIS,
inspecting the lateral and longitudinal trim actuator output lever
self-locking nuts for correct torque and applying torque marking. For
each inspection where the nuts are not torqued to the correct value and
must be adjusted, the torque marking would be removed and reapplied.

Interim Action

    We consider this AD to be an interim action because Airbus
Helicopters is currently developing a modification that will address
the unsafe condition identified in this AD. Once this modification is
developed, approved and available, we might consider additional
rulemaking.

Costs of Compliance

    We estimate that this proposed AD would affect 100 helicopters of
U.S. Registry and that labor costs average $85 per work-hour. Based on
these estimates, we expect the following costs:
    Applying torque and torque marking to the lateral and longitudinal
trim actuator output levers would require 1 work-hour for a labor cost
of $85. No parts would be needed, so the cost for the U.S. fleet would
total $8,500.
    Visually inspecting for correct torque would require 0.5 work-hour
for a labor cost of about $43. No parts would be needed, so the total
cost for the U.S. fleet would be $4,300 per inspection cycle.

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 proposed 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, 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 to the extent that
it justifies making a regulatory distinction; 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.
    We prepared an economic evaluation of the estimated costs to comply
with

this proposed AD and placed it in the AD docket.

    Abstract: Respondents are owners or operators of sulfuric acid
plants. A sulfuric acid plant is any facility producing sulfuric acid
(H2SO4) by the contact process by burning
elemental sulfur, alkylation acid, hydrogen sulfide, organic sulfides
and mercaptans, or acid sludge. A sulfuric acid plant does not include
facilities where conversion to sulfuric acid is used primarily as a
means of preventing emissions to the atmosphere of sulfur dioxide
(SO2) or other sulfur compounds.
    Form Numbers: None.
    Respondents/affected entities: Owners or operators of sulfuric acid
plants.
    Respondent's obligation to respond: Mandatory (40 CFR part 60,
subpart H).
    Estimated number of respondents: 53 (total).
    Frequency of response: Initially, occasionally, and semiannually.
    Total estimated burden: 13,409 hours (per year). Burden is defined
at 5 CFR 1320.3(b).
    Total estimated cost: $1,551,276 (per year), which includes
$238,500 in either annualized capital and/or operation & maintenance
costs.
    Changes in the Estimates: There is an increase of 4,815 hours in
the total estimated respondent burden in this ICR as compared to the
ICR currently approved by OMB. This is not due to any program changes;
rather, it is due to the correction of a mathematical error.

Acting Director, Collection Strategies Division.
