Executive Summary

Acute and chronic aggregate dietary food and drinking water exposure and risk assessments were conducted using the Dietary Exposure Evaluation Model software with the Food Commodity Intake Database (DEEM-FCID) Version 3.16, which uses food consumption data collected from 2003-2008 from the U.S. Department of Agriculture's (USDA's) National Health and Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA).  The analysis was conducted to support a human health risk assessment for the proposed use and tolerances of linuron on coriander, dill, horseradish, parsley, celeriac, rhubarb, and dry pea.   This memo was reviewed by two peer reviewers of the Dietary Exposure Science Advisory Council (DESAC), per the DESAC Standard Operating Procedure (SOP) 2012.1.

Acute Dietary Exposure Assessment: The acute dietary exposure assessments incorporated recommended and/or established tolerance-level residues, and used DEEM default processing factors.  The acute assessment assumed that all registered and proposed crops were treated (100% crop treated; %CT).  Estimated drinking water concentrations (EDWCs) from the Environmental Fate and Effects Division (EFED) (89.05 ppb) were also included.  Because different toxicological points of departure (PODs) were selected for females 13-49 years old and for the general U.S. population, two separate dietary exposure analyses were conducted.  The results of the acute analysis indicate that the acute dietary (food and drinking water) exposure and risk does not exceed HED's level of concern [i.e., <100% acute population adjusted dose (aPAD)] for the general U.S. population, and all population subgroups, including females 13-49 years old.  At the 95[th] percentile of exposure, the resulting acute dietary (food and drinking water) risk estimates utilized 4.3% of the aPAD for the general U.S. population and 10% for all infants, the most highly exposed population subgroup.  At the 95[th] percentile of exposure, the resulting acute dietary (food and drinking water) risk estimate utilized 5.7% of the aPAD for females 13-49 years old.

Chronic Dietary Exposure Assessment: The chronic dietary (food and drinking water) exposure assessment for linuron incorporated recommended and/or established tolerance-level residues and used DEEM default processing factors.  Average %CT estimates provided by the Biological and Economic Analysis Division (BEAD) were also incorporated into the assessment for the existing uses, and EDWCs from EFED (48.8 ppb) were also included.  The results of the chronic analysis indicate that chronic dietary (food and drinking water) exposure and risk does not exceed HED's level of concern [i.e., <100% chronic population adjusted dose (cPAD)] for the U.S. population and all population subgroups.  The resulting chronic dietary (food and drinking water) risk estimates utilized 22% of the cPAD for the general U.S. population and utilized 60% of the cPAD for children 1-2 years old, the most highly exposed population subgroup.

Cancer Dietary Exposure Assessment: Linuron is classified as a "Group C Carcinogen" and quantification of human cancer risk is not required.

I.  Introduction

Dietary risk assessment incorporates both exposure and toxicity of a given pesticide.  For acute and chronic assessments, the risk is expressed as a percentage of a maximum acceptable dose (i.e., the dose that HED has concluded will result in no unreasonable adverse health effects).  This dose is referred to as the population adjusted dose (PAD).  The PAD is equivalent to the point of departure (POD; no observed adverse effect level, NOAEL; lowest observed adverse effect level, LOAEL, e.g.) divided by the required uncertainty or safety factors.

For acute and non-cancer chronic exposures, HED is concerned when estimated dietary risk exceeds 100% of the PAD.  References that discuss the acute and chronic risk assessments in more detail are available on the EPA/pesticides web site:  "Available Information on Assessing Exposure from Pesticides, A User's Guide," 21-JUN-2000, web link:  http://www.epa.gov/fedrgstr/EPA-PEST/2000/July/Day-12/6061.pdf; or see SOP 99.6 (20-AUG-1999).

The most recent dietary risk assessment for linuron was conducted by Donna Davis (D350545, 04/15/2008).

II.  Residue Information

Residues of Concern: The residue definitions for enforcement of tolerance and for risk assessment are identical, namely, linuron and metabolites convertible to 3,4-dichloroaniline (3,4-DCA).  The residues of concern are summarized in Table 1.

The terminal residues of concern in plants, animals, and drinking water are linuron (parent) and metabolites convertible to 3,4-DCA, including 3,4-dichlorophenylurea (DCPU), desmethoxy-linuron (DCPMU), desmethyl linuron, and hydroxy-norlinuron.

Established Tolerances: Permanent tolerances for linuron are currently established in/on a wide variety of crops (40 CFR §180.184), including a Section 18 registration on lentils (revocation date of 12/31/2014) and on crops with regional registrations.

Recommended Tolerances: The Interregional Research Project No. 4 (IR-4) submitted a petition (PP#2E8083) to allow linuron use on coriander (fresh and seed), dill, horseradish, parsley, and dry pea.  HED previously evaluated exposure risk from linuron use on rhubarb and celeriac during tolerance reassessment (S. Recore, D281845, 03/27/2002); however, the uses are also included in the currently proposed label.  Therefore, HED has reevaluated the risk from linuron use on rhubarb and celeriac.  The tolerance recommendations are outlined in Table 2.

Residue Data used for Acute and Chronic Assessments: HED used tolerance-level residues for the proposed and registered crops, and assumed that 100% of the registered and proposed crops were treated for the acute assessment, and incorporated average %CT was used for the registered crops when available for the chronic assessment.  DEEM default processing factors were used for dried potato, corn syrup, and dried beef meat.  Table 2 lists HED-recommended tolerances for the proposed crops used in the dietary assessment.

Meat, Milk, Poultry and Eggs: There are no feed items associated with this current petition.  Cowpea commodities would affect the dietary burden of cattle but they are not included in the petition for dry peas.  Dry peas only includes the following commodities listed under 40 CFR§180.1(g): Cajanus cajan (includes pigeon pea); Cicerspp.(includes chickpea and garbanzo bean); Lens culinaris (lentil);Pisumspp.(includes dwarf pea, garden pea, green pea, English pea, field pea, and edible pod pea).  Therefore, the previous livestock dietary intake calculations and resulting tolerance recommendations are not changed.

III.  Percent Crop Treated Information

A Screening Level Usage Analysis (SLUA) entitled, "Usage Report Package in Support of a Tolerance Petition for the Herbicide Linuron, BEAN DP# 410336" (J. Alsadek, 04/10/2013) was provided by BEAD.

The acute dietary analysis incorporated 100%CT for all registered and proposed commodities.

The chronic dietary analysis incorporated average %CT data for asparagus (25%), carrots (85%), celery (25%), corn (1.0%), cotton (1.0%), potatoes (5.0%), sorghum (1.0%), soybeans (1.0%), sweet corn (1.0%), and wheat (1.0%).

Please refer to Attachment 5 for the PCT data provided by BEAD.

IV.  Drinking Water Data

The drinking water residues used in the dietary risk assessment were provided by EFED (H. Zhong, D405829, 06/25/2013 and H. Zhong, D405829, 06/19/2013) and incorporated directly into this dietary assessment.  Water residues were incorporated in the DEEM-FCID into the food categories "water, direct, all sources" and "water, indirect, all sources."  The drinking water assessment assumes a total toxic residue approach.  The EDWC for surface water from the current assessment (89.05 ppb) is based on the California lettuce scenario and is higher than the previous EDWC estimates.  Thus, the surface water concentration of 89.05 ppb was used for the acute dietary exposure assessments.  The EDWC for ground water (48.8 ppb) based on the Wisconsin corn scenario and is used in the chronic dietary exposure assessment.

EDWCs for the acute assessments were estimated using the Pesticide Root Zone Model- Exposure Analysis Modeling System (PRZM-EXAMS).   The EDWC for the chronic assessment was estimated using PRZM-GW (groundwater).  The EDWCs from D405829 are listed in Table 3.  The models and their descriptions are available at the EPA internet site: http://www.epa.gov/oppefed1/models/water/.

V.  DEEM-FCID Program and Consumption Information

Linuron acute and chronic dietary exposure assessments were conducted using the Dietary Exposure Evaluation Model software with the Food Commodity Intake Database DEEM-FCID, Version 3.16, which incorporates consumption data from 2003 to 2008 from USDA's NHANES/WWEIA.  The data are based on the reported consumption of more than 20,000 individuals over two non-consecutive survey days.  Foods "as consumed" (e.g., apple pie) are linked to EPA-defined food commodities (e.g., apples, peeled fruit - cooked; fresh or N/S; baked; or wheat flour - cooked; fresh or N/S, baked) using publicly available recipe translation files developed jointly by USDA/ARS and EPA.  For chronic exposure assessment, consumption data are averaged for the entire U.S. population and within population subgroups.  However, for acute exposure assessment, consumption data are retained as individual consumption events.  Based on analysis of the 2003-2008 WWEIA consumption data, which took into account dietary patterns and survey respondents, HED concluded that it is most appropriate to report risk for the following population subgroups: the general U.S. population, all infants (<1 year old), children 1-2, children 3-5, children 6-12, youth 13-19, adults 20-49, females 13-49, and adults 50-99 years old.

For an acute exposure assessment, individual one-day food consumption data are used on an individual-by-individual basis.  The reported consumption amounts of each food item can be multiplied by a residue point estimate and summed to obtain a total daily pesticide exposure for a deterministic exposure assessment, or "matched" in multiple random pairings with residue values and then summed in a probabilistic assessment.  The resulting distribution of exposures is expressed as a percentage of the aPAD on both a user (i.e., only those who reported eating relevant commodities/food forms) and a per-capita (i.e., those who reported eating the relevant commodities as well as those who did not) basis.  In accordance with HED policy, per capita exposure and risk are reported for analyses performed at all levels of refinement.  However, for deterministic assessments, any significant differences in user vs. per capita exposure and risk are specifically identified and noted in the risk assessment.

For a chronic dietary exposure assessment, an estimate of the residue level in each food or food-form (e.g., orange or orange juice) on the food commodity residue list is multiplied by the average daily consumption estimate for that food/food form to produce a residue intake estimate.  The resulting residue intake estimate for each food/food form is summed with the residue intake estimates for all other food/food forms on the commodity residue list to arrive at the total average estimated exposure.  Exposure is expressed in mg/kg body weight/day and as a percent of the cPAD.  This procedure is performed for each population subgroup.

VI.  Toxicological Information

The toxicity database for linuron is robust and the data requirements are satisfied.  The HED Hazard and Science Policy Council (HASPOC) waived the required subchronic neurotoxicity, subchronic dermal toxicity, and subchronic inhalation toxicity studies (TXR# 0056667 and TXR# 0056666). With repeated dosing in test animals, linuron produces two primary effects: (1) changes in the hematopoietic system in rats, mice, and dogs; and (2) changes in the male reproductive system in developing rats.

Because different toxicological PODs were selected for females 13-49 years old and for the general U.S. population, two separate dietary exposure analyses were conducted.  To estimate acute dietary exposure to the general U.S. population and remaining population subgroups excluding females 13-49 years old, an oral POD was selected based on decreases in rearing and motor activity seen at the LOAEL of 100 mg/kg/day in the acute neurotoxicity study (NOAEL = 20 mg/kg/day).  A composite uncertainty factor of 100 to account for interspecies extrapolation and intraspecies variability is applied to the NOAEL to derive an aPAD of 0.2 mg/kg/day.  To estimate acute dietary exposure to females of childbearing age, an oral POD was selected based on increased post-implantation loss and fetal/litter resorptions seen at the LOAEL of 50 mg/kg/day in the rat developmental toxicity study (NOAEL = 12 mg/kg/day).  A composite uncertainty factor of 100 to account for interspecies extrapolation and intraspecies variability is applied to the NOAEL to derive an aPAD of 0.12 mg/kg/day.

To estimate chronic dietary exposure to the general U.S. population and all population subgroups, an oral POD was selected based on hematological effects (increased met- and sulf-hemoglobin levels) seen at the LOAEL of 3.5 mg/kg/day in the chronic dog toxicity study (NOAEL = 0.77 mg/kg/day).  A composite uncertainty factor of 100 to account for interspecies extrapolation and intraspecies variability is applied to the NOAEL to derive a cPAD of 0.0077 mg/kg/day.

The linuron risk assessment team evaluated the quality of the toxicity and exposure data and, based on these data, recommended that the Food Quality Protection Act (FQPA) Safety Factor be reduced to 1X.

Based on the weight of evidence of the available scientific data, linuron is classified as a "Group C Carcinogen" and quantification of human cancer risk is not required.

The toxicity endpoints pertinent for human dietary risk assessment are summarized in Table 4.

VII.  Results/Discussion

As stated above, for acute and chronic assessments, HED is concerned when dietary risk exceeds 100% of the PAD.  The DEEM-FCID analyses estimate the dietary exposure of the U.S. population and various population subgroups.  The results reported in Tables 5 and 6 are for the general U.S. Population, all infants (<1 year old), children 1-2, children 3-5, children 6-12, youth 13-19, females 13-49, adults 20-49, and adults 50-99 years.

Results of Acute Dietary (Food and Drinking Water) Exposure and Risk Analysis: The results of the acute dietary exposure and risk analysis at the 95[th], 99[th], and 99.9[th] percentile of exposure are reported in Table 5.

*The subpopulation(s) with the highest exposure & risk estimates.

 VIII.  Characterization of Inputs/Outputs

The linuron dietary exposure risk estimates are mostly unrefined and considered conservative since they: (1) assume that 100% of the proposed crops were treated with linuron; (2) use established or recommended tolerance-level residues for all crops; (3) use default/conservative processing factors for processed commodities; and (4) use conservative, modeled drinking water estimates.  The tolerances are derived from crop field trials or conservative data translations and default processing factors.  The field trials were conducted at maximum application rates and minimum pre-harvest intervals.  Additional refinements to the assessment could include use of %CT information for proposed crops and any available monitoring data.  However, at this time, the dietary risks (food and water) of linuron are <10% of the aPAD and <60% of the cPAD and are not of concern to HED; therefore no further refinement is required.

 IX.  Conclusions

 A conservative dietary (food and drinking water) exposure and risk assessment was performed for linuron.  The assumptions incorporated into the assessment included 100% CT for the proposed commodities, estimated %CT assumptions or assumed 100% CT for some registered commodities, default processing factors, established/proposed tolerance level residues, and conservative EDWCs.  The acute dietary (food and drinking water) exposure estimates are below HED's level of concern (<100% aPAD) for all population subgroups at the 95[th] percentile of exposure.  The chronic dietary (food and drinking water) exposure estimates are also below HED's level of concern (<100% cPAD) for the general U.S. population and all population subgroups.  Linuron acute dietary (food and drinking water) risk utilized 5.7% of the aPAD for females 13-49 years old, 4.3% of the aPAD for the general U.S. population, and 10% of the aPAD for all infants, the most highly exposed population subgroup at the 95[th] percentile of exposure.  Linuron chronic dietary risk utilized 22% of the cPAD for the general U.S. population and 60% of the cPAD for children 1-2 years old, the most highly exposed population subgroup.  HED is confident that the assessment does not underestimate risk to the general U.S. population or any population subgroup.

Recycling of hazardous secondary materials for the purpose of the exclusions or exemptions from the hazardous waste regulations must be legitimate. Hazardous secondary material that is not legitimately recycled is discarded material and is a solid waste. In determining if their recycling is legitimate, persons must address all the requirements of this paragraph and must consider the requirements of paragraph (b) of this section.
260.43(a)
                                 9VAC20-60-18.
IBR in 9VAC20-60-260A.
                                       X

Legitimate recycling must involve a hazardous secondary material that provides a useful contribution to the recycling process or to a product or intermediate of the recycling process. The hazardous secondary material provides a useful contribution if it:

IBR in 9VAC20-60-260A.
                                       X

The recycling process must produce a valuable product or intermediate. The product or intermediate is valuable if it is:

IBR in 9VAC20-60-260A.
                                       X

The generator and the recycler must manage the hazardous secondary material as a valuable commodity when it is under their control. Where there is an analogous raw material, the hazardous secondary material must be managed, at a minimum, in a manner consistent with the management of the raw material or in an equally protective manner. Where there is no analogous raw material, the hazardous secondary material must be contained. Hazardous secondary materials that are released to the environment and are not recovered immediately are discarded.

In making a determination that a hazardous secondary material is legitimately recycled, persons must evaluate all factors and consider legitimacy as a whole. If, after careful evaluation of these considerations, the factor in this paragraph is not met, then this fact may be an indication that the material is not legitimately recycled. However, the factor in this paragraph does not have to be met for the recycling to be considered legitimate. In evaluating the extent to which this factor is met and in determining whether a process that does not meet this factor is still legitimate, persons can consider exposure from toxics in the product, the bioavailability of the toxics in the product and other relevant considerations.

14 CFR Part 460

Interpretation Concerning Involvement of NASA Astronauts During a
Licensed Launch or Reentry

AGENCY: Federal Aviation Administration, DOT.

ACTION: Interpretation.

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

SUMMARY: This interpretation responds to a request from the National
Aeronautics and Space Administration (NASA) regarding whether the space
transportation regulations of the Federal Aviation Administration (FAA)
would restrict NASA astronauts from performing operational functions
during a commercial space launch or reentry under license from the FAA.

DATES: Effective December 2, 2013.

Underwood, Deputy Manager, Operations Integration Division;

Office of the Chief Counsel, International Law, Legislation, and
Regulations Division, Federal Aviation Administration; email

SUPPLEMENTARY INFORMATION:

Background

    On July 3, 2013, NASA asked the FAA whether the FAA would restrict
NASA astronauts, who are U.S. Government employees, from engaging in
operational functions during an FAA-licensed launch or reentry. NASA
noted that all NASA astronauts undergo extensive training and must meet
rigorous medical and training requirements. NASA will also ensure
astronauts complete training specific to each launch and reentry
operator's vehicle and operations.
    Specifically, NASA asked whether, under the FAA's statute and
regulations, a NASA astronaut flying as a space flight participant
could engage in ``all nominal and off-nominal operational functions,''
including ``the conduct of aborts, emergency response, and monitoring
and operating environmental controls and life support systems.'' NASA
also asked the FAA whether NASA's astronauts could ``perform
operational activities up to and including flight.'' In response to
NASA's question, the FAA examined the launch and reentry scenarios
currently envisioned, and concludes that NASA astronauts may perform
these functions in FAA-licensed launches and reentries.

Scenarios

    The FAA understands that the following scenarios are likely, but
not definite. It is the FAA's understanding that a NASA astronaut's
interaction with the controls of a launch or reentry vehicle may vary
depending on a launch or reentry operator's designs and operational
procedures, which are currently under development. During a nominal
launch, a launch operator under an FAA license would most likely
conduct the ascent using a flight computer as the primary means of
controlling the flight path of the vehicle. Any persons on board would
not likely affect the flight path of the launch vehicle. If an
emergency situation arose, a NASA astronaut could override the launch
operator's flight computer to initiate an abort from the launch vehicle
and take manual control of the spacecraft atop the launch vehicle. NASA
astronaut emergency operations could include manually initiating an
abort, using thrusters to orient a capsule to support chute deployment,
and subsequent deployment of any parachutes. Emergency operations could
also include the NASA astronaut manually piloting a vehicle to a water
or runway landing.
    For a reentry, a licensed operator's flight computer could serve as
the primary means of controlling the flight path of the vehicle during
a nominal reentry. A NASA astronaut might manually initiate the reentry
burn, and the flight computer could conduct the reentry of the vehicle
during nominal operations. The NASA astronaut could also have the
capability to take manual control over the reentry vehicle in an off-
nominal or emergency situation. During an off-nominal or emergency
situation, the NASA astronaut would, much of the time, be using
procedures or training prepared by the reentry operator.

Discussion

A. Space Flight Participants Who are NASA Astronauts

    Based on the above scenarios, we conclude that, under 51 U.S.C. ch.
509 (Chapter 509), the FAA's space regulations at 14 CFR ch. III, and
consistent with the FAA's discussion of its human space flight
requirements,\1\ a NASA astronaut may engage in operational functions,
up to and including piloting the vehicle, the conduct of aborts,
emergency response, and monitoring and operating environmental controls
and life support systems, and the launch or reentry would remain under
FAA jurisdiction.
---------------------------------------------------------------------------

    \1\ Human Space Flight Requirements for Crew and Space Flight
Participants, Final Rule, 71 FR 75616 (Dec. 15, 2006) (``Human Space
Flight Rule'').
---------------------------------------------------------------------------

    Chapter 509 addresses crew and space flight participants, and,
according to Chapter 509's definition, NASA astronauts are space flight
participants. Chapter 509 defines ``crew'' as ``any employee of a
licensee or transferee, or of a contractor or subcontractor of a
licensee or transferee, who performs activities in the course of that
employment directly relating to the launch, reentry, or other operation
of or in a launch vehicle or reentry vehicle that carries human
beings.'' 51 U.S.C. 50902(2). Conversely, a ``space flight
participant'' is ``an individual, who is not crew, carried within a
launch vehicle or reentry vehicle.'' Id. Sec.  50902(17). Because a
NASA astronaut is not an employee of a licensee or transferee, or of a
contractor or subcontractor of a licensee or transferee, a NASA
astronaut is not crew. Consequently, a NASA astronaut who is being
carried within a launch or reentry vehicle is a space flight
participant.

B. Limitations

    Chapter 509 does not specify any limitations on a space flight
participant's conduct or operations during a launch or reentry.
Similarly, FAA regulations implementing Chapter 509 for space flight
participants, codified at 14 CFR part 460, also do not specify any
limitations on a space flight participant's conduct or operations
during a launch or reentry. See 14 CFR 460.41, et. seq.\2\ The only
place where the FAA limits space-flight-participant conduct or
operations is in the preamble to the Human Space Flight rule that
created part 460. There the FAA states that:
---------------------------------------------------------------------------

    \2\ The pertinent FAA regulations simply require that space
flight participants: (1) be informed of risk; (2) execute a waiver
of claims against the U.S. Government; (3) receive training on how
to respond to emergency situations; and (4) not carry any weapons
onboard. See 14 CFR Sec. Sec.  460.45-460.53.

    For public safety reasons, the FAA will not allow space flight
participants to pilot launch or reentry vehicles at this time. A
space flight participant who wants to pilot a launch or reentry
vehicle would have to become an employee or independent contractor
of the operator to acquire vehicle and mission-specific training.
The operator will be in a better position to evaluate the skills of
an employee or independent contractor than of a space flight
participant, particularly as those skills relate to the requirements
of the operator's particular vehicle. The FAA acknowledges that this
restriction may create a dilemma for someone who wishes to acquire
training in order to become employed, but, while the technology is
so new, it is important for public safety that pilots be highly
skilled at the outset.\3\
---------------------------------------------------------------------------

    \3\ Human Space Flight Requirements Final Rule, 71 FR at 75618.

    As can be seen, the FAA's concern with space flight participants
interacting with a launch or reentry vehicle was based on the
possibility that space flight participants would not have the proper
vehicle and mission-specific training. However, as NASA notes, NASA
astronauts must meet rigorous medical and training requirements, which
include training specific to each mission, launch vehicle, and reentry
vehicle. Because NASA astronauts are not the untrained space-flight
participants originally contemplated by the FAA, the considerations
underlying the policy have, at best, a limited applicability to NASA
astronauts. Thus, for the scenarios currently envisioned, NASA
astronauts may engage in operational activities during a licensed
launch or reentry to ensure safety and mission success

C. Jurisdiction

    We note that Chapter 509 does not apply to launches or reentries
the U.S. Government carries out for itself. 51 U.S.C. 50919(g).
Accordingly, NASA is not carrying out the launches or reentries that
are subject to Chapter 509. In the event, not contemplated in this
interpretation, that a NASA astronaut

exercised sufficient operational control to carry out the launch or
reentry, Sec.  50919(g) would serve as a bar to FAA licensing the
activity.
    In the scenarios described above, as currently under development by
launch and reentry operators, the NASA astronaut would likely not
affect the flight path of the vehicle during a nominal launch. During a
launch, the astronaut would likely only manipulate the flight path of
the vehicle if an emergency arose. Accordingly, section 50919(g) would
not limit a NASA astronaut's ability to engage in operational functions
during launch. Most of the conduct or operations would simply
constitute the execution of emergency training required of space flight
participants by Sec.  460.51.
    The analysis for a reentry is similar to that of a launch, with
some additional consideration for the possible manual operation of the
reentry vehicle by a NASA astronaut. Specifically, a NASA astronaut
could initiate reentry manually, but because the scenarios have the
reentry operator's flight computer directing the reentry, the NASA
astronaut's interaction would not be sufficient to constitute NASA
carrying out the reentry. Additionally, the NASA astronaut's exercise
of manual control over the vehicle in an off-nominal situation would
also not rise to NASA carrying out the reentry because, as discussed
above, in an off-nominal situation, the astronaut would largely be
implementing procedures created by a commercial launch or reentry
operator for purposes of safety or mission success.
    In conclusion, Chapter 509 and the FAA's regulations impose no
operational constraints on NASA astronauts for the scenarios envisioned
here.

SUPPLEMENTARY INFORMATION: The FAA invites public comment on the
request to release approximately 2.766 acres of airport
property at the St. Louis Lambert International Airport (STL) under the
provisions of 49 U.S.C. 47107(h)(2). On April 9, 2019, the Director of
the St. Louis Lambert International Airport requested from the FAA that
approximately 2.766 acres of property be released for sale
to St. Louis County for the purpose of road widening and utilities. On
April 30, 2019, the FAA determined that the request to release property
at St. Louis Lambert International Airport (STL) submitted by the
Sponsor meets the procedural requirements of the Federal Aviation
Administration and the release of the property does not and will not
impact future aviation needs at the airport. The FAA may approve the
request, in whole or in part, no sooner than thirty days after the
publication of this Notice.
    The following is a brief overview of the request:
    St. Louis Lambert International Airport (STL) is proposing the
release of a parcel, totaling 2.766 acres. The release of
land is necessary to comply with Federal Aviation Administration Grant
Assurances that do not allow federally acquired airport property to be
used for non-aviation purposes. The sale of the subject property will
result in the land at the St. Louis Lambert International Airport (STL)
being changed from aeronautical to non-aeronautical use and release the
surface lands from the conditions of the AIP Grant Agreement Grant
Assurances. In accordance with 49 U.S.C. 47107(c)(2)(B)(i) and (iii),
the airport will receive fair market value for the property.
    Any person may inspect, by appointment, the request in person at
the FAA office listed above under FOR FURTHER INFORMATION CONTACT. In
addition, any person may, upon appointment and request, inspect the
application, notice and other documents determined by the FAA to be
