EFED is responding to " Error Only" and public comments for the napropamide RED. Many of the comments were substantive and led to changes in the RED. Some of these included application rates, modeling inputs, and submission of additional data.

Registrant Comment Napropamide is a pre emergent herbicide, generally applied to bare ground. The product works by disrupting the growth process during germination and therefore soil incorporation or wateringin is recommended. To be effective, napropamide must reach the zone of weed seed germination, which is typically 2 to 4 inches below the soil surface. All the product labels bear wording recommending either mechanical incorporation or incorporation through irrigation.

Response to Registrant The registrant is correct in noting that the labels require incorporation to 2 4 inches ( 5.08 to 10.16 cm) of soil depth following application. However, the required time until incorporation ranges from 24 hours to 3 weeks, and significant rainfall leading to runoff and erosion could occur Page 2 of 10 in that time frame. Therefore, runoff prior to proper incorporation could occur and EFED modeled an incorporation depth of 0.5 cm for all uses.

Registrant Comment The cancelled WP formulation was registered for use on food crops at the 6 lb ai/ A rate, which is referenced in many of the EPA documents. This use rate is not found on the current product labels for food crop uses, only for turf and ornamental uses.

Response to Registrant According to the Use Closure Memorandum dated 4/ 29/ 04, the registrant intends to support all currently registered products EXCEPT DEVRINOL 50 WP Selective ( EPA Reg. No. 70506 26), DEVRINOL 50WP Ornamental ( EPA Reg. No. 70506 29), and DEVRINOL ( EPA Reg. No. 70506 32). EFED removed all references to the 50 WP formulation in the current reregistration document. However, the 50WP label is not the only one with an application rate of 6 lbs ai/ A. The label with Reg. No. 70506 33 contains a one time application rate of 6 lbs ai/ A to fruit, nut, and citrus crops. Therefore, EFED did assess the use of 70506 33.

Registrant Comment Many of the risk assessment documents use the scenario of two applications for some crops. However, a second application is permitted only for certain crops in the Western region ( see label for Devrinol 50 DF Selective ( 70506 36) for a map of which states this includes).

Response to Registrant EFED modeled the application of two applications for all of the orchard and vineyard scenarios because label 70506 36 does allow application of up to 8 lbs ai/ A in split applications. The only orchard crops to which the label does not allow two applications in all geographic regions of the U. S are kiwifruit and olives. EFED has PRZM EXAMS scenarios for almost all listed orchard and vineyard crops to which two applications can be made in all regions.

Registrant Comment In instances where more than one application is permitted, the interval of 7 days between applications ( the input parameter used by EPA in risk assessments) does not reflect agricultural practices for herbicides. An interval of 90 days would be considered more representative for this herbicide. Page 3 of 10 Response to Registrant EFED modeled an application interval of 60 days for all scenarios with multiple applications. While 90 days may be more representative, the PRZM EXAMS PE 4 shell would not accommodate that interval in some scenarios because the modeled dates occurred in two different crop years. The use of 60 days is in accordance with labels for napropamide applied to turf and ornamentals. EFED also believes that the 60 day interval is appropriate for the other crops with multiple applications.

Registrant Comment The vast majority of the agricultural uses ( with the exception of turf, mint and cranberries), receive band treatments such that the actual amount of product applied to the field ( vs. broadcast) is lower than a calculated per acre rate. In band treatments, the product is applied to the area directly under the tree ( usually a 4 8 foot wide band) and not in the aisles ( or middle rows). Compared to broadcast methods, this application scenario results in only about 1/ 3 of an acre receiving treatment. Although Devrinol may be applied to any crop as a broadcast treatment, this method is not economical for growers and is used less than 10% of the time in favor of band treatments.

Response to Registrant EFED realizes that in many situations pre emergence herbicides such as napropamide may be banded instead of broadcasted to an entire field. Therefore, EFED modeled potential exposure to plant and animals using both the maximum labeled rate( s) and the " typical" banded rates.

Registrant Comment The cranberry maximum use rate is 9 lb ai/ A. Although a rate of 15 lb ai/ A appears on the label ( Devrinol 10 G), it is registered for use only in WA and OR, and only if the bog soil type is muck soil. There are an estimated 34,000 acres of cranberries grown in the US [ 13,000 in WI, 15,000 in MA, 3,000 in NJ, 1,000 in WA and 1500 in OR; USDA, NASS, The Cranberry Institute]. The cranberry acres in WA, the only region of the US with muck soils, represent only 3% of the total cranberry acres, and not all of those acres have muck soils. The use rates in that region are in fact closer to 6 to 7 lb ai/ A and not 15 as used in the EFED risk assessments [ personal communication, Delmer Robison, Western Growers Supply, Bandon, OR].

Response to Registrant To model aquatic exposure from applied pesticides in cranberry production, EFED uses a modified version of the Interim Rice Model. The standard practice is to model the maximum application rate applied to any scenario and crop because the label allows that rate. Page 4 of 10 Registrant Comment In the EFED Risk Assessment for the Napropamide Reregistration Eligibility Document ( page 10), information from the National Agriculture Statistics Service ( NASS) was cited regarding napropamide usage in the US. NASS reported that napropamide was used on treated acres for the following crops ( representing 75% of the napropamide use in 1997):

Tomatoes   23.5 % Tobacco   20% Cranberries 11.8% Hot Peppers 10.2% Strawberries   8.9%

NASS reports that 448,000 lbs ai were applied in 1997. UPI is providing more detailed sales and use figures. Due to the confidentiality of the following information, this commercial and financial information has been removed to a confidential appendix and is cited by CROSS REFERENCE NUMBER 1.

Response to Registrant The more recent use and sales figures do not change the overall risk conclusions.

Registrant Comment The Agency is concerned about the fact that an acceptable explanation has not been provided to explain the large difference in half life between the lab aerobic metabolism study and the half lives in the field dissipation studies. We acknowledge that an interpretation for the differences has not been provided. However, there are substantial data available to indicate that the field data numbers are valid and that the product does actually degrade rapidly in the field. In the field dissipation studies cited in the EFED risk assessment, the half life ranged from 17 24 days. One of the studies was done with the DF formulation and comprised 2 applications, separated by one month. The half life in the latter study was 17.4 days, with NO indication of any accumulation. A total of 17 field degradation studies were undertaken in Germany, USA and Canada using various formulations and application timings, resulting in a range of half life values between 9 and 120 days. Additional studies will be submitted which support the reliability of the field data and provide experimental evidence that there is no accumulation. We believe that EPA's concern that there may be accumulation is not justified based on the weight of the evidence from higher tier, field dissipation studies.

The fact that the fastest routes of dissipation for the product based on lab studies are photolysis ( soil and water) does not negate the results of the field data. EPA comments that soil photolysis is not operative because of soil incorporation and aqueous photolysis is not operative in the Page 5 of 10 presence of organics. The extent to which these mechanisms operate in the field is speculation, whereas there is substantial field data that confirms the product does not accumulate in the soil.

Response to Registrant EFED has performed a cursory analysis of these studies which clearly show a reduced half life in the field compared to the laboratory. The submitted aerobic soil metabolism study ( MRID 46459104) states that napropamide degraded by hydrolysis and by loss of the N Alkyl group to yield naphthoxy propionic acid, followed by non extractable bound residues and CO 2 . However, the data do not support the registrant's conclusions. Napropamide is hydrolytically stable, the half lives in the laboratory studies do not indicate significant degradation, naphthoxy propionic acid was not formed in significant quantities, and " extractable" residues ( acetonitrile) accounted for the bulk of the residues in the aerobic soil metabolism studies submitted by the registrant. Therefore, the most likely source of dissipation in the environment are runoff, erosion, and leaching.

Registrant Comment We believe that the use of the correct and more realistic modeling assumptions, such as   the correct vapor pressure ( 1.7x10 7 torr), water solubility ( 74 mg/ L), aqueous photolysis half life ( 6.8 min)   field dissipation half life ( in place of aerobic soil metabolism half life),   a realistic time between applications ( such as 90 days) for those uses with more than one application per season rather than a default of 7 days, and   a lower lbs. ai use rate to reflect the band applications rather than broadcast,

will reduce the calculated EECs.

Response to Registrant EFED reran the PRZM EXAMS modeling using the inputs suggested by the registrant. The vapor pressure used in previous modeling was incorrect and was changed to reflect the correct registrant value, but made no difference in the EECs. The suggested water solubility ( 74 mg/ L) also made no difference because PRZM EXAMS only uses the water solubility as an upper bound. The EECs were in the ug/ L ( parts per billion, ppb) range and were not affected by the water solubility in the mg/ L ( parts per million, ppm) range. EFED originally used an aqueous photolysis half life of 26 minutes for the sum of parent + Isomer I + Isomer II instead of 6.8 minutes for parent napropamide only. In the revised assessment, EFED did use the registrant value of 6.8 minutes upon further consideration. Given the relative rapidity of photodegradation for both half lives and the fact that EXAMS divides the aqueous phototolysis rate by 124 to account for suspended sediment and shading, the different half lives made no difference. It is scientifically invalid to use field dissipation half lives in PRZM EXAMS modeling because field Page 6 of 10 dissipation takes into account many laboratory dissipation processes, and including it in modeling " double counts" ( overestimates) disappearance of a compound. PRZM EXAMS takes laboratory dissipation half lives and predicts field dissipation half lives. In the previous " error only" version of the RED chapter, EFED assumed an application interval of 7 days in the absence of information. The use of an extended application window is a valid comment and it affected the modeling results by reducing EECs. EFED also considered the banding of napropamide as a valid comment and specifically modeled those applicable scenarios.

Registrant Comment Although EPA does acknowledge that napropamide is a pre emergent herbicide, generally applied to bare ground, it is not clear that this is really taken into account in the risk assessments. The vast majority of the agricultural uses ( with the exception of turf, mint and cranberries), are via band applications such that the actual amount of product applied to the field ( vs. broadcast) is lower. Further, the product must be either soil incorporated ( where applicable) or watered in, making less product available for runoff such that only treatments from the edges of agricultural sites ( i. e., a very small part of the actual amount applied) is available for runoff.

Response to Registrant EFED did model the runoff from field treated both broadcast and banded where applicable. Incorporation depth on the label may not be relevant in an orchard or vineyard because mechanical incorporation is not possible due to existing root structures. The labels allow up to 3 weeks before incorporation for some crops and locations and large rainfall events may occur prior to that time. Therefore, runoff from excess rainfall may exceed incorporation in this case.

Registrant Comment The Agency believes that chronic exposure to aquatic organisms is possible because of the " potential persistence" which may cause chronic exposure to aquatic organisms. We believe that EPA significantly over estimates the amount of napropamide in the soil which is available for runoff. In addition, the aquatic dissipation mechanism on which EPA relies   aqueous photolysis  may not be the only mechanism available to reduce the amount of product in the water phase. Sufficient weight must be given to the following:   Based on the use pattern, the amount of napropamide reaching aquatic environments is much less than that estimated by EPA.   The field dissipation data indicate rapid dissipation.   A natural sediment water study shows that the product partitions from the water phase into the sediment with a half life of 24 34 days making napropamide less available to the aquatic organisms. Page 7 of 10 Response to Registrant The registrant contends that the persistence in the field is less than EFED predicts, and therefore the exposure in aquatic systems will be less than predicted. As stated earlier, the dominant routes of dissipation in the field appear to be runoff, erosion, and leaching. The registrant also contends that the degradation in aquatic systems is based on both photolysis and metabolic degradation. Any metabolic degradation would only be expected to occur in the water phase because the halflives in sediment were 254 and 403 days. However, the exact study to which the registrant is referring is unknown. The OPPIN database of submitted studies lists MRID 45074201 as the submitted study for degradation in water ( Guideline 162 4), but this study is a method validation study for determining levels of napropamide in water.

Registrant Comment In assessing risk to terrestrial organisms, EPA significantly over estimated exposure primarily due to the use of non realistic input values as discussed above. Terrestrial non target organism exposure from the use of this herbicide is most likely to occur as a result of spray drift due to the use pattern. The product is generally applied in a band ( with the exception of turf, mint and cranberries) under and near the agricultural crop being grown. As a result, it is not likely that there would be significant residues in other areas of the treated fields.

Response to Registrant EFED assumes that drift can occur both in the field and outside the field.

Registrant Comment In areas adjacent to the treated fields, there is a potential for spray drift to non target organisms. Given the mode of action of this product, it is not likely to impact established plants since there is no incorporation of the product in these areas. Two additional studies are being submitted which tested seedling emergence   with and without soil incorporation. These show that the results are clearly more severe with incorporation  a practice not applicable to off site areas. It should also be pointed out that the product dissipates rapidly in the soil and by photolysis in water and therefore the actual exposure to non target organisms will decline quickly.

Response to Registrant The results form the seedling emergence studies are included in this assessment. The registrant has not demonstrated that the product dissipates rapidly in soil other than runoff, erosion, and leaching. Page 8 of 10 Registrant Comment The RQ's calculated will improve with the use of more appropriate inputs to the EEC calculations. Nevertheless, even if the RQ's as calculated using the conservative lab input to the modeling exceed the Levels of Concern, there is no evidence after 25 years of Devrinol use suggesting that actual adverse effects occur from the existing uses.

Response to Registrant EFED believes that the lack of reporting of adverse ecological effects does not mean they are not occurring. Ecological incidents can provide useful information on the circumstances where impacts occur in the field and are therefore a valuable tool for risk characterization. However, reliance on the frequency of incidents may significantly underestimate the extent of the actual impacts. Adverse ecological effects cannot be assumed to be reliably detected and reported. Before an incident can be reported, it must be observed and attributed to the pesticide. Also, if kills are not reported and investigated promptly, there will be little chance of documenting the cause. Reports of investigated incidents often do not get submitted to EPA, since reporting by states is voluntary and some investigators may believe that they do not have the resources to submit incident reports to EPA.

Registrant Comment The agency identified key information gaps that prevented the full assessment of the potential adverse effects of napropamide to aquatic plants and algae. Registrant comment: The registrant submitted two studies of acute toxicity of napropamide to Lemna minor ( MRID 464591 11) and Anabaena sp. ( MRID 464591 12).

EFED response Both of these studies have been classified as supplemental, and they have been incorporated into the risk assessment. These studies have been used to assess risks to aquatic plants and algae associated with napropamide use; however, EFED acknowledges the existence of uncertainties related to the use of these supplemental studies in the revised risk assessment. Specifically, the Anabaena study was conducted for 3 days instead of the guideline requirement of 5 days. As a result there is uncertainty associated with the EC 50 that was identified in this study. The Lemna study was conducted with a non guideline species instead of the guideline required species, Lemna gibba.

Registrant comment The registrant submitted two seedling emergence studies ( MRID 464591 13 and 464591 14) in support of their claim that napropamide is less toxic to plants outside the area of application because it is not incorporated in those areas. Page 9 of 10 EFED response MRID 464591 13 is classified as supplemental, and does not provide additional plant toxicity information because this guideline has already been satisfied with an acceptable study. MRID 464591 14 is classified as invalid and will not be included in the revised risk assessment. Because MRID 464591 14 is an invalid study, EFED cannot use these data to evaluate the registrant's comment that napropamide is less toxic to non target plants when not incorporated. Based on EFED's revised risk assessment, RQs are generally higher for plants under scenarios in which napropamide is not incorporated.

The agency also identified key information gaps that prevented the full assessment of the potential adverse chronic effects of napropamide to aquatic animals. Registrant comment: The registrant submitted a freshwater fish sub chronic ( 28 day) study ( MRID 464591 09) and an aquatic invertebrate life cycle test with Daphnia magna ( MRID 464787 04).

EFED response The data from these studies have been incorporated into the revised risk assessment. The subchronic study on freshwater fish has been classified as supplemental, as it does not meet Agency guidelines. The study also did not identify the ages of the fish when the study began, so there is uncertainty associated with the use of this study in establishing a NOAEC upon which to base the estimate of chronic risk to freshwater fish. Chronic studies were not submitted for marine/ estuarine fish or invertebrates, so these data requirements have not been fulfilled.

Registrant comment In order to estimate the risk of napropamide to non target insects, the registrant submitted two studies on honey bee acute contact toxicity ( MRID 464591 15 and 464591 16), one of which also tests acute oral toxicity ( MRID 464591 15).

EFED response The two tests for contact toxicity have been determined to be invalid, and the data obtained from these studies will not be used in the revised risk assessment. The oral toxicity study has been classified as supplemental, and has been incorporated into the revised risk assessment.

Registrant comment The registrant submitted proposed changes to labels specifying revised ( in most cases reduced) application rates, numbers of applications, and an application interval of 90 days. Page 10 of 10 EFED response EFED must use language contained in active labels to establish the use patterns for modeling napropamide exposure in the ecological risk assessment. The proposed label changes were not incorporated into the revised risk assessment because they have not been officially accepted. However, EFED recognizes that some proposed label changes have the potential to reduce risks to some organisms if they are incorporated into the labels.

14 CFR Part 39

[Docket No. FAA-2011-1226; Directorate Identifier 2011-NM-006-AD;
Amendment 39-17001; AD 2012-06-20]
RIN 2120-AA64

Airworthiness Directives; Fokker Services B.V. Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. This AD
was prompted by a report that the fuel crossfeed valves cannot be
controlled when only emergency electrical power is available, that an
unwanted configuration of the indication logic for the fuel fire
shutoff valve was introduced during production, and that current fuel
crossfeed indications are based on selection by the flightcrew instead
of actual position of the crossfeed valve actuators. This AD requires
modifying the crossfeed valve control and power supply, the crossfeed
indication logic and power supply, and the indication logic for the
fuel fire shutoff valve; modifying the overhead panel; and for certain
airplanes, modifying the transfer logic of the center wing fuel tank.
We are issuing this AD to prevent failure of an in-flight engine re-
light following a double engine flame-out event, which could result in
loss of the airplane.

DATES: This AD becomes effective May 24, 2012.
    The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of May 24, 2012.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the U.S. Department of
Transportation, Docket Operations, M-30, West Building Ground Floor,
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on November 8, 2011 (76
FR 69163). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:

    A recent safety review revealed that the fuel crossfeed valves
cannot be controlled when only emergency electrical power is
available.
    This condition, if not corrected, could (in combination with
other factors) prevent an in-flight engine re-light following a
double engine flame-out event, possibly resulting in loss of the
aeroplane.
    Another review revealed that an unwanted configuration of the
fuel fire shut-off valve indication logic had been introduced during
production on a limited number of F28 Mark 0100 aeroplanes.
    Furthermore, most of the current fuel crossfeed indications are
based on the crossfeed selection made by the flight crew and not on
the actual positions of the crossfeed valve actuators. In
combination with other factors, the current crossfeed indications
may mislead flight crews, possibly resulting in single engine in-
flight shutdowns and/or unnecessary precautionary landings.
    For the reasons described above, this [EASA] AD requires
modifications of the crossfeed valve control and power supply, of
the crossfeed indication logic and power supply and of the fuel fire
shut-off valve indication logic.
* * * * *
Required actions also include modifying the overhead panel (introducing
provisions for a modified crossfeed indication), and, for certain
airplanes, modifying the transfer logic of the center wing fuel tank.
You may obtain further information by examining the MCAI in the AD
docket.

Comments

    We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (76 FR 69163, November 8,
2011) or on the determination of the cost to the public.

Explanation of Changes Made to This AD

    We have revised the heading for and the wording in paragraph (i) of
this AD; this change has not changed the intent of that paragraph. We
have also revised the document citations throughout this AD to more
clearly identify the documents and their attachments.

Conclusion

    We reviewed the relevant data and determined that air safety and
the public interest require adopting the AD with the changes described
previously--and minor editorial changes. We have determined that these
minor changes:
     Are consistent with the intent that was proposed in the
NPRM (76 FR 69163, November 8, 2011) for correcting the unsafe
condition; and
     Do not add any additional burden upon the public than was
already proposed in the NPRM (76 FR 69163, November 8, 2011).

Costs of Compliance

    We estimate that this AD will affect 6 products of U.S. registry.
We also estimate that it will take about 86 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Required parts will cost about $4,180 per
product. Where the service information lists required parts costs that
are covered under warranty, we have assumed that there will be no
charge for these parts. As we do not control warranty coverage for
affected parties, some parties may incur costs higher than estimated
here. Based on these figures, we estimate the cost of this AD to the
U.S. operators to be $68,940, or $11,490 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 AD will not have federalism implications
under Executive Order 13132. This AD will 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. We prepared a regulatory evaluation
of the estimated costs to comply with this AD and placed it in the AD
docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM (76 FR 69163, November 8,
2011), the regulatory evaluation, any comments received, and other
information. The street address for the Docket Operations office
(telephone<PHONE_NUMBER>) is in the ADDRESSES section. Comments will
be available in the AD docket shortly after receipt.
