Enclosed is the Tier II drinking water assessment for proposed uses of the active ingredient pyraclostrobin on Oats and Oilseed including canola and flax (Section 3 request for Headline Fungicide – DP Barcode 334534); Corn, Soybean, and Sugar-beets (Section 3 request for Headline Fungicide – DP Barcode 340588); Fresh Herbs (crop group 19) and Tropical Fruits (avocado, black sapote, canistel, mamey, sapote, mango, papaya sapodilla, and star apple) (IR-4 request for Pristine Fungicide – DP Barcode 336190); and Turf and Ornamentals (Section 3 request for Insignia Fungicide - DP Barcode 342584).

This Tier II drinking water assessment was completed for the proposed use of pyraclostrobin on Turf and Ornamentals, because this use represents the highest use rate of the proposed and registered uses.

If you have any further questions regarding this assessment, please contact Gabriel Rothman at<PHONE_NUMBER>.

introduction

This Tier II Drinking Water Assessment for pyraclostrobin is being submitted in order to determine if the new uses will increase the residue concentration of pyraclostrobin in surface and ground water, to quantify these changes, and to characterize the exposure pathways as influenced by the fate and transport properties of pyraclostrobin.  The new uses include the following:

Ground and Aerial Application on Oats and Oilseed including canola and flax (Section 3 request for Headline Fungicide – DP Barcode 334534)

In-Furrow Application on Corn, Soybean, and Sugar-beets (Section 3 request for Headline Fungicide – DP Barcode 340588); Fresh Herbs (crop group 19)

Ground and Aerial Application on Tropical Fruits (avocado, black sapote, canistel, mamey, sapote, mango, papaya sapodilla, and star apple) (IR-4 request for Pristine Fungicide – DP Barcode 336190)

Aerial Application on Turf and Ornamentals (Section 3 request for Insignia Fungicide - DP Barcode 342584).

This assessment was based on the application of the highest seasonal use rate (proposed or registered) of pyraclostrobin.  The aerial application on turf and ornamentals contains the highest seasonal application at 0.5 lbs a.i./acre with 6 maximum seasonal applications at 14 day intervals. The proposed use rate for the aerial application on Turf and Ornamentals is the same as for the registered use of pyraclostrobin for ground application on turf (please see the,“Environmental Fate and Ecological Risk Assessment for the Registration of Pyraclostrobin”, submitted February 6, 2002.).  However, EFED believes that the aerial use of pyraclostrobin on turf and ornamentals will possess the upper-bound concentrations in surface and ground water since spray drift increases and application efficiency decreases in an aerial application technique.

EXECUTIVE SUMMARY

The subject chemical addressed in this drinking water assessment is identified by the chemical pyraclostrobin (cabamic acid, [2-[[[1-(4-chlorophenyl)-1H-pyrazol-3-yl[oxy]methyl]phenyl]methoxy-,meth yl ester).  The trade name for this compound is Insignia Fungicide.  The labeled formulation of Insignia Fungicide contains the active ingredient of pyraclostrobin by 20 percent with other ingredients accounting for the remaining 80 percent.

The chemical identification number is 099100.  Figure 1 shows the chemical composition of pyraclostrobin

Figure 1.  Chemical structure of pyraclostrobin.

Measures of exposure for pyraclostrobin in this drinking water assessment are obtained through modeling efforts only, since national-scale monitoring data were not identified. The Tier II drinking water assessment was performed using the Tier II PRZM/EXAMS (PE4V01 perl shell with PRZM 3.12 beta dated 5/24/01 and EXAMS version 2.98, 7/18/02) to assess surface water.  Ground water concentrations were estimated using a Tier I SCI-GROW model (version 2.3, May 16, 2006) since a Tier II model has not been developed to assess ground water.

Acute effects of pyraclostrobin residues in drinking water are expressed in annual peak one-in-ten year concentrations, chronic effects in annual average one-in-ten year concentrations, and cancer effects in 30-year average concentrations.  The upper-bound Tier II modeling predicts that the concentrations of pyraclostrobin in surface water are not likely to exceed 35.6 µg/L for the peak concentration, 2.3 µg/L for the annual average concentration, and 1.5 µg/L for the 30-year average concentrations.  The ground water assessment was based on the latest proposed use rate of pyraclostrobin on turf and ornamentals.  The SCI-GROW model predicts the acute and chronic concentrations of pyraclostrobin in shallow ground water to be 0.02 g/L (0.02 ppb).

PROBLEM FORMULATION

Pyraclostrobin is not likely to reach ground water since pyraclostrobin is tightly bound to soils with Kocs between 6,000 mg/L and 16,000 mg/L in all soil studies with an arithmetic mean of 9,304 mg/L and median of 7,889 mg/L.  However, EFED believes pyraclostrobin can potentially contaminate surface water through runoff.  Laboratory and terrestrial field studies suggest that pyraclostrobin is moderately persistent in aerobic environments with aerobic aquatic and aerobic soil half-lives above 80 days but more rapidly decays in an anaerobic soil environment with half-lives around 3 days.  Pyraclostrobin is also practically stable with respect to hydrolysis but does undergo rapid photolysis.  Pyraclostrobin is also subject to spray drift in the proposed foliar applications.

This drinking water assessment only addresses the parent compound.  Major degredates of pyraclostrobin were not found to be of toxicological concern.

Figure 2 is the conceptual model showing all exposure pathways from pyraclostrobin aerial application on Turf and Ornamental effects on drinking water.  For additional information on pyraclostrobin fate and transport properties, please refer to the original drinking assessment for the Florida Turf scenario included with the, “Environmental Fate and Ecological Risk Assessment for the Registration of Pyraclostrobin”, submitted February 6, 2002.

Analysis

Surface Water

Two Turf scenarios and six Nursery scenarios, as a surrogate to the Ornamentals crop group, were considered in the surface water assessment [please see EFED policy memo titled, “Outdoor Nursery Pesticide Root Zone Model (PRZM) Scenarios for Use in Surface Water Assessments”, dated July 26, 2007].  A PCA factor of 1.0 was used for all scenarios consistent with EFED policy (see EFED policy memo, “Golf Course Adjustment Factors for Simulated Aquatic Exposure Concentrations”, dated December 7, 2005).

The PRZM/EXAMS fate parameters and crop-specific inputs and are shown in Tables 1 and 2 respectively.  The only data gaps in this assessment includes the lack of aerobic aquatic and anaerobic aquatic metabolism studies.  Table 1 contains a description of how these data gaps are addressed in the surface water assessment.  Another potential limitation in this assessment is that the Nursery scenarios did not address irrigation.  The upper-bound concentrations should simulate as much exposure to water from sources such as irrigation channels.  However, the PRZM model version 3.12 beta does not simulate irrigation.

The estimated concentrations of pyraclostrobin in surface water for each scenario are shown in Table 3.  The upper-bound estimated pyraclostrobin residue concentration in surface water appears to result from the New Jersey Nursery scenario with 6 aerial applications of 0.5 lbs a.i./acre, 14 day intervals.  The PRZM/EXAMS output files are provided in Appendix A.

ground Water

Ground water concentrations were estimated using a Tier I SCI-GROW model (version 2.3, May 16, 2006).  The ground water concentrations generated by SCI-GROW are based on the largest 90-day average recorded during the sampling period.  Since there is relatively little temporal variation in ground water concentrations compared to surface water, the model predicted value can be considered to represent both the acute and chronic values.

g/L (0.02 ppb).  The SCI-GROW output files for both scenarios are provided in Appendix B.

Exposure Characterization

This assessment demonstrates that exposure of pyraclostrobin in surface water is very sensitive to runoff.  The New Jersey Nursery scenario used in PRZM/EXAMS to diagnose the upper-bound pyraclostrobin residue surface water concentration reflects a region with high rainfall and high vulnerability to runoff.

As expected, pyraclostrobin did not show high levels of ground water concentrations.  The highly immobile property of pyraclostrobin most probably contributes to this result.  The predicted SCI-GROW concentration should be conservative typical of a Tier I model.

SUPPLEMENTARY INFORMATION:

I. Introduction

    These test guidelines are part of a series of test guidelines
established by OCSPP for use in testing pesticides and chemical
substances to develop data for submission to the Agency under TSCA (15
U.S.C. 2601 et seq.), FIFRA (7 U.S.C. 136 et seq.), and section 408 of
the FFDCA (21 U.S.C. 346a).
    The test guidelines serve as a compendium of accepted scientific
methodologies and protocols that are intended to provide data to inform
regulatory decisions under TSCA, FIFRA, and/or FFDCA. The test
guidelines provide guidance for conducting the test, and are also used
by EPA, the public, and the companies that are subject to data
submission

requirements under TSCA, FIFRA, and/or FFDCA.

II. General Information

A. Does this action apply to me?

    This action is directed to the public in general. Although this
action may be of particular interest to those persons who are or may be
required to conduct testing of chemical substances under TSCA, FFDCA,
and/or FIFRA, the Agency has not attempted to describe all the specific
entities that may be affected by this action. If you have any questions
regarding the applicability of this action to a particular entity,
consult the appropriate person listed under FOR FURTHER INFORMATION
CONTACT.

B. How can I get copies of this document and other related information?

    1. Docket for this document. EPA has established a docket for this
action under docket identification (ID) number EPA-HQ-OPP-2009-0681.
Publicly available docket materials are available either in the
electronic docket at http://www.regulations.gov, or, if only available
in hard copy, at the Office of Pesticide Programs (OPP) Regulatory
Public Docket in Rm. S-4400, One Potomac Yard (South Bldg.), 2777 S.
Crystal Dr., Arlington, VA. The hours of operation of this Docket
Facility are from 8:30 a.m. to 4 p.m., Monday through Friday, excluding
legal holidays. The Docket Facility telephone number is<PHONE_NUMBER>.
    2. Electronic access to OCSPP test guidelines. To access OCSPP test
guidelines electronically, please go to http://www.epa.gov/ocspp/pubs/frs/home/testmeth.htm. You may also access the test guidelines in
http://www.regulations.gov, grouped by series under docket ID numbers:
EPA-HQ-OPPT-2009-0150 through EPA-HQ-OPPT-2009-0159 and EPA-HQ-OPPT-
2009-0576.

III. What action is EPA taking?

    EPA is announcing the availability of the final test guidelines for
Group B--Product Performance Test Guidelines for Public Health Uses of
Antimicrobial Agents in OCSPP Series 810--Product Performance Test
Guidelines:
    1. General Considerations for Public Health Uses of Antimicrobial
Agents (OCSPP 810.2000).
    2. Sterilants--Efficacy Data Recommendations (OCSPP 810.2100).
    3. Disinfectants for Use on Hard Surfaces--Efficacy Data
Recommendations (OCSPP Guideline 810.2200).
    4. Sanitizers for Use on Hard Surfaces--Efficacy Data
Recommendations (OCSPP 810.2300).
    These final test guidelines address efficacy testing for
antimicrobial agents intended to be used on hard, inanimate,
environmental surfaces and which bear label claims as sterilants,
disinfectants, and sanitizers.
    As guidance documents, the test guidelines are not binding on
either EPA or any outside parties, and EPA may depart from the test
guidelines where circumstances warrant and without prior notice. At
places in this guidance, the Agency uses the word ``should.'' In this
guidance, use of ``should'' with regard to an action means that the
action is recommended rather than mandatory. The procedures contained
in the test guidelines are recommended for generating the data that are
the subject of the test guideline, but EPA recognizes that departures
may be appropriate in specific situations. Alternatives to the
recommendations described in the test guidelines may be proposed, and
the Agency will assess them for appropriateness on a case-by-case
basis.

IV. How were these test guidelines developed?

    The product performance guidelines for antimicrobial agents were
last updated in 1982 under the ``Pesticide Assessment Guidelines--
Subdivision G, Product Performance.'' Since then, the Agency has
presented several issues at two separate meetings of the FIFRA
Scientific Advisory Panel (SAP) related to the conduct of studies for
antimicrobial agents (the first meeting September 9-10, 1997, announced
in the Federal Register issue of July 14, 1997 (62 FR 37584) (FRL-5731-
4) and the second meeting July 17-19, 2007, announced in the Federal
Register issue of March 14, 2007 (72 FR 11867) (FRL-8118-7).
Information and recommendations regarding these two FIFRA SAPs can be
found at the Office of Science and Coordination and Policy's Web site
at http://www.epa.gov/scipoly/sap/index.htm. The test guidelines were
also published for comment in the Federal Register issue of January
2010 (75 FR 4380) (FRL-8437-2) and revised based on comments received
from industry. In addition to formatting changes to incorporate the
test guidelines into the OCSPP 810 Series, EPA has added sections that
incorporate new guidelines and clarifications from other guidance
documents. In particular, data recommendations for testing against the
spore formers Bacillus anthracis and Clostridium difficile have been
added.

DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

Notice of Availability of the Record of Decision (ROD) for the
Cal Black Memorial Airport, Halls Crossing Replacement Airport

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of Availability.

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

SUMMARY: In accordance with the National Environmental Policy Act of
1969 (NEPA, 42 U.S.C. 4321 et seq.) and Council on Environmental
Quality regulations (40 CFR parts 1500-1508), the Federal Aviation
Administration announces the availability of the Record of Decision for
the Cal Black Memorial Airport, replacement airport for the Halls
Crossing Airport.

ADDRESSES: Copies of the ROD may be viewed during regular business
hours at the following locations:
    1. Federal Aviation Administration Airports Division, Suite 315,
1601 Lind Avenue SW., Renton, WA 98057.

    3. San Juan County Courthouse, County Executive Office, 117 S.
Main, Monticello, Utah 84535.
    The ROD will also be available on the following Web site: http://halls.crossing.airportnetwork.com/.

FOR FURTHER INFORMATION CONTACT: Janell Barrilleaux, Environmental
Program Manager, Federal Aviation Administration Airports Division,
Northwest Mountain Region, 1601 Lind Avenue SW., Renton, WA 98057. Mrs.
Barrilleaux may be contacted during business hours at<PHONE_NUMBER>
(phone),<PHONE_NUMBER> (fax), or via email at
<EMAIL_ADDRESS>
SUPPLEMENTARY INFORMATION: The Halls Crossing replacement airport was
originally proposed in 1966 due to the inadequacy of the existing Halls
Crossing airstrip. After completion of numerous planning studies, the
Federal Aviation Administration completed an Environmental Impact
Statement (EIS) (June, 1990) with the cooperation of the National Park
Service (NPS) and the Bureau of Land Management (BLM). A Record of
Decision (ROD) was issued in August 1990 approving the development of
what is now named the Cal Black Memorial Airport. Concurrently, the BLM
approved an amendment of a land plan which allowed the conveyance of
land to San Juan County for the construction of the new airport.
    In 1990, the National Parks Conservation Association (NPCA),\1\ et
al.\2\ brought suit concerning the adequacy of the 1990 Final EIS and
the adequacy of the BLM plan amendment and land transfer process. In
its July 7, 1993 decision, the U.S. Court of Appeals for the Tenth
Circuit concluded that ``the action of FAA approving the project based
on a finding of `no significant impact' and `no significant adverse
impact' [was] arbitrary and capricious.'' The court proceeding stated:
---------------------------------------------------------------------------

    \1\ Note: The title of the organization as documented in the
1993 United States Court of Appeals case National Parks Conservation
Association, et al. v Federal Aviation Administration, et al.
    \2\ Other parties to the suit included the Southern Utah
Wilderness Alliance, the Sierra Club, and Deborah L. Threedy.

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

    We therefore REVERSE the BLM's plan amendment and the transfer
of land. We REMAND for further proceedings to determine whether the
land should be retained under BLM control and management or
reconveyed to San Juan County under a newly proposed land use plan
amendment. In the case of the FAA, the airport has already been
built. This does not mean that a remand would be meaningless,
however. On remand, the FAA should re-analyze the impact of the
airport under section 4(f) and section 2208.\3\ The FAA may
determine that it must make use of studies not utilized in the
current FEIS. If a ``significant'' impact is found, section 4(f) and
section 2208 require that all reasonable steps be taken to mitigate
the damage or adverse impact. We therefore REVERSE the FAA's
determination of no significant impact and REMAND to the FAA for
further proceedings consistent with this decision.
---------------------------------------------------------------------------

    \3\ Note: In 1994, the provisions of the Airport and Airway
Improvement Act of 1982 were codified in U.S. Code Title 49, chapter
471, subchapter I.

    In response to the court remand, FAA, in cooperation with BLM
and NPS prepared a Supplemental EIS (SEIS).\4\ The Draft SEIS for
the Cal Black Memorial Airport (Replacement Airport for Halls
Crossing Airport) was published on December 12, 2014. The 45-day
comment period included an opportunity to request a public hearing;
however, no responses were received requesting a hearing. The
following parties submitted comments to the FAA on the Draft SEIS
during the comment period: U.S. Department of the Interior, U.S.
Environmental Protection Agency, BLM, and the NPCA. An errata sheet
was drafted to identify changes that were made to the Draft SEIS in
response to comments received. Additionally, an appendix was added
(Appendix J) to document each comment received, and FAA's response
to each comment. These additional documents, in combination with a
CD containing the Draft SEIS, constitute the Final SEIS for the
Replacement Airport at Halls Crossing. The Final SEIS for the Cal
Black Memorial Airport (replacement airport for the Halls Crossing
Airport) was published on May 8, 2015.
---------------------------------------------------------------------------

    \4\ BLM addressed its requirements through its revisions to
their Resource Management Plan in 2008. Bureau of Land Management
Monticello Field Office, Record of Decision and Approved Resource
Management Plan (November 2008).

    The SEIS described potential environmental consequences that could
result from the continued operation of the Cal Black Memorial Airport
to resources located within the Project Area. Direct effects of the new
airport (its construction) as well as indirect effects (airport
operations) were identified in the 1990 FEIS. The SEIS provided further
evaluation of actual and potential aircraft noise impacts, as well as
Section 4(f) impacts and cumulative impacts. Evaluation of noise
impacts focused exclusively on the effect of aircraft noise on GCNRA
and surrounding lands. Chapter III, Environmental Consequences,
presents the analysis for noise impacts, Section 4(f) impacts, and
Cumulative Effects resulting from the operation of the Cal Black
Memorial Airport.
    The FAA has determined, based on the noise analysis conducted for
the SEIS that as there are no significant impacts related to the
continued operation of the Cal Black Memorial Airport, there is no need
for any mitigation measures under either Section 4(f) or Section 2208.
    In addition, the FAA has confirmed that the ROD for the 1990 EIS

SUPPLEMENTARY INFORMATION:
    Title: FERC-725S, Emergency Preparedness and Operations (EOP)
Reliability Standards.
    OMB Control No.: 1902-0270.
    Type of Request: Three-year approval of the FERC-725S information
collection requirements with no changes to the current reporting
requirements.
    Abstract: The Electricity Modernization Act of 2005, which is Title
XII of the Energy Policy Act of 2005 (EPAct 2005), added a new section

215 to the Federal Power Act (FPA).\1\ FPA section 215 requires a
Commission-certified Electric Reliability Organization (ERO) to develop
mandatory and enforceable Reliability Standards, subject to Commission
review and approval. Section 215 of the FPA requires a Commission-
certified ERO to develop mandatory and enforceable Reliability
Standards, subject to Commission review and approval. In 2006, the
Commission certified North American Electric Reliability Corporation
(NERC) as the ERO pursuant to section 215 of the FPA. FERC-725S
consists of Emergency Preparedness and Operations (EOP) Reliability
Standards, EOP-004-4 (Event Reporting), EOP-005-3 (System Restoration
from Blackstart Resources), EOP-006-3 (System Restoration
Coordination), EOP-008-2 (Loss of Control Center Functionality), EOP-
010-1 (Geomagnetic Disturbance Operations), and EOP-011-1 (Emergency
Operations). These Reliability Standards enhance reliability by:
---------------------------------------------------------------------------

    \1\ 16 U.S.C. 824o. The approved Reliability Standards are
available on the Commission's eLibrary document retrieval system on
the NERC website, www.nerc.com.
---------------------------------------------------------------------------

    (1) Providing accurate reporting of events to NERC's event analysis
group to analyze the impact on the reliability of the bulk electric
system (Reliability Standard EOP-004-4).
    (2) delineating the roles and responsibilities of entities that
support system restoration from blackstart resources which generate
power without the support of the bulk electric system (Reliability
Standard EOP-005-3).
    (3) clarifying the procedures and coordination requirements for
reliability coordinator personnel to execute system restoration
processes (Reliability Standard EOP-006-3).
    (4) refining the required elements of an operating plan used to
continue reliable operations of the bulk electric system in the event
that primary control center functionality is lost (Reliability Standard
EOP-008-2).
    (5) addressing the effects of operating Emergencies by ensuring
each Transmission Operator and Balancing Authority has developed
Operating Plan(s) to mitigate operating Emergencies, and that those
plans are coordinated within a Reliability Coordinator Area (EOP-010-
1).
    (6) streamlining the requirements for Emergency operations of the
Bulk Electric System. Attachment 1, which is incorporated into
Requirements R2 and R6, provides the process and descriptions of the
levels used by the Reliability Coordinator when communicating the
condition of a Balancing Authority that is experiencing an Energy
Emergency (EOP-011-1).
    The 60-day notice was published on November 18, 2020 (85 FR 73477),
and no comments were received.
    Type of Respondents: Public utilities subject to the FPA.
    Estimate of Annual Burden \2\ and cost: \3\ With the exception of
adjustments due to the Commission's recent experience with this
information collection, the Commission estimates there will be no
changes in the annual public reporting burden for the FERC-735S, as
follows:
---------------------------------------------------------------------------

    \2\ Burden is defined as the total time, effort, or financial
resources expended by persons to generate, maintain, retain, or
disclose or provide information to or for a Federal agency. For
further explanation of what is included in the information
collection burden, refer to 5 Code of Federal Regulations 1320.3.
    \3\ Commission staff estimates that the industry's skill set and
cost (for wages and benefits) for FERC-725S are approximately the
same as the Commission's average cost. The FERC 2020 average salary
plus benefits for one FERC full-time equivalent (FTE) is $172,329/
year (or $83.00/hour).
    \4\ The number of respondents is based on NERC compliance
registration information as of October 2, 2020.

                                                                        FERC-725S

September 2019 QA/QC Review of Enclosure 2 Information for EPA 2016 ICR for Erie Coke (Excel file)

Mr. Schneider: You have been identified as a reviewer for your company's information supplied to EPA for the 2016 Information Collection Request (ICR). If you are not correct person, please forward to the current employee responsible for this review.

Thank you again for your efforts in providing your facility information. Now is the time to correct, update, or add to your responses from 2016 for Enclosure 2. Attached is your facility's information in one Excel file.
Please refer to the `Review Instructions' worksheet of the attached spreadsheet for specific review instructions.
The Enclosure 2 data are organized into three groups within the spreadsheet:
A. Air Stack Tests
B. Process Data
C. Non-Stack Test Data (e.g., Opacity, Water Tests, Material Tests, COG Tests, etc.)

Resources worksheets (tabs R-1 through R-4) also are available for your reference and use.
Please review all data compiled by the EPA Contractor. If your data is not correct, please revise or add it to the applicable worksheet. Highlight (in yellow) any changes made with any cell and describe the change in the "Facility Review Comments" column of the applicable worksheet.
If any of the currently missing information is considered "confidential business information" (CBI), please note "CBI" in the empty data cell. Then please provide this CBI information using the CBI procedures described in the original ICR letter sent by EPA in 2016. We can provide again if needed.
If you have any questions, please first send an email to BOTH Gabrielle Raymond, the EPA contractor from RTI, and me at the email addresses below. If we need to speak on the phone, we can follow-up with a call, but we need an email first to ensure contact.
<EMAIL_ADDRESS><EMAIL_ADDRESS>

We will be entering your Enclosure 2 data into the Coke oven RTR subpart CCCCC Modelling file soon after the first of the year 2020, so we need to get all the QA/QC work done during the Fall 2019.
Note that we will be summarizing CBI data in Enclosure 1 separately at some not yet determined point in the future.
Thank you in advance for your work, time and expense helping us get good quality data.
