DEPARTMENT OF HOMELAND SECURITY

Coast Guard

[USCG-2012-0099]

Prince William Sound Regional Citizens' Advisory Council Charter
Renewal

AGENCY: Coast Guard, DHS.

ACTION: Notice of recertification.

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

SUMMARY: The purpose of this notice is to inform the public that the
Coast Guard has recertified the Prince William Sound Regional Citizens'
Advisory Council (PWSRCAC) as an alternative voluntary advisory group
for Prince William Sound, Alaska. This certification allows the PWSRCAC
to monitor the activities of terminal facilities and crude oil tankers
under the Prince William Sound Program established by statute.

DATES: This recertification is effective for the period from March 1,
2012 through February 28, 2013.

FOR FURTHER INFORMATION CONTACT: LCDR Mike Franklin, Seventeenth Coast
Guard District (dpi), by phone at<PHONE_NUMBER>, email
<EMAIL_ADDRESS>or by mail at P.O. Box 25517, Juneau,
Alaska 99802.

SUPPLEMENTARY INFORMATION:

Background and Purpose

    As part of the Oil Pollution Act of 1990, Congress passed the Oil
Terminal and Oil Tanker Environmental Oversight and Monitoring Act of
1990 (the Act), 33 U.S.C. 2732, to foster a long-term partnership among
industry, government, and local communities in overseeing compliance
with environmental concerns in the operation of crude oil terminals and
oil tankers.
    On October 18, 1991, the President delegated his authority under 33
U.S.C 2732(o) to the Secretary of Transportation in Executive Order
12777, section 8(g) (see 56 FR 54757; October 22, 1991) for purposes of
certifying advisory councils, or groups, subject to the Act. On March
3, 1992, the Secretary redelegated that authority to the Commandant of
the USCG (see 57 FR 8582; March 11, 1992). The Commandant redelegated
that authority to the Chief, Office of Marine Safety, Security and
Environmental Protection (CG-5) on March 19, 1992 (letter
5402).
    On July 7, 1993, the USCG published a policy statement, 58 FR
36504, to clarify the factors that shall be considered in making the
determination as to whether advisory councils, or groups, should be
certified in accordance with the Act.
    The Assistant Commandant for Marine Safety and Environmental
Protection (CG-5), redelegated recertification authority for advisory
councils, or groups, to the Commander, Seventeenth Coast Guard District
on February 26, 1999 (letter 16450).
    On September 16, 2002, the USCG published a policy statement, 67 FR
58440, that changed the recertification procedures such that applicants
are required to provide the USCG with comprehensive information every
three years (triennially). For each of the two years between the
triennial application procedure, applicants submit a letter requesting
recertification that includes a description of any substantive changes
to the information provided at the previous triennial recertification.
Further, public comment is not solicited prior to recertification
during streamlined years, only during the triennial comprehensive
review.
    On March 1, 2003, the Coast Guard was transferred from the
Department of Transportation (DoT) to the Department of Homeland
Security (DHS) and retained the previous delegations that were provided
while it was in the DoT.
    The Alyeska Pipeline Service Company pays the PWSRCAC $2.9 million
annually in the form of a longterm contract. In return for this

funding, the PWSRCAC must annually show that it ``fosters the goals and
purposes'' of OPA 90 and is ``broadly representative of the communities
and interests in the vicinity of the terminal facilities and Prince
William Sound.'' The PWSRCAC is an independent, nonprofit organization
founded in 1989. Though it receives federal oversight like many
independent, non-profit organizations, it is not a federal agency. The
PWSRCAC is a local organization that predates the passage of OPA 90.
The existence of the PWSRCAC was specifically recognized in OPA 90
where it is defined as an ``alternate voluntary advisory group.''
    Alyeska funds the PWSRCAC, and the Coast Guard makes sure the
PWSRCRC operates in a fashion that is broadly consistent with OPA 90.

Recertification

    By letter dated February 27th, 2012, the Commander, Seventeenth
Coast Guard certified that the PWSRCAC qualifies as an alternative
voluntary advisory group under 33 U.S.C. 2732(o). This recertification
terminates on February 28, 2013.

    Dated: March 5, 2012.
T.P. Ostebo,
Rear Admiral, U.S. Coast Guard Commander, Seventeenth Coast Guard
District.

For agricultural crops, both S and I term daily dose estimates are equivalent because exposure assumptions and inputs are screening level/ unrefined; the quantitative hazard estimates they are compared to incorporate duration, and inform the S and I T MOEs. For greenhouse roses, only short term exposure is expected, therefore only S T daily doses are calculated. 3 MOE = NOAEL/ Inhalation Daily Dose ( S T inhalation NOAEL = 25 mg/ kg/ day and I T inhalation NOAEL = 20 mg/ kg/ day) 4 Although oil seed crops can be high acreage ( such as cotton in the US, or rapeseed in Canada), the crops listed on the label are assumed to be " typical" as defined in HED Science Advisory Council for Exposure Draft Policy # 9, dated 7/ 5/ 00, and therefore assessed as such. 5 DF = dry flowable formulation/ WDG, F = flowable/ liquid formulation 6 For greenhouse roses, only S T inhalation exposure is expected, therefore only S T MOEs are reported ( for rationale, see discussion in Section 4.1) 7 NA, not applicable, ORETF data is not graded as PHED is graded. The ORETF data were designed to replace the present PHED data with higher confidence, higher quality data. 8 Taken from AD memo on Azoxystrobin Mold Retardant 2.08 SC, D. Aviado, 7/ 2/ 04, D299065 7.2 Occupational Postapplication Exposure and Risk 51 The proposed occupational uses for azoxystrobin addressed in this document involve foliar applications. Therefore, there is a potential for postapplication exposure to scouts, harvesters and other field workers. However, because no appropriate dermal endpoints were identified for this exposure potential, and postapplication inhalation exposure is expected to be negligible, an occupational postapplication risk assessment was not conducted. A dislodgeable foliar residue ( DFR) study for the use of azoxystrobin on grapes was submitted to the Agency previously, but has not been employed in past assessments and is not employed in this assessment because HED determined there is no hazard via the dermal route ( Review of Acceptability of Data Submitted to Support the Registration of New Uses of Azoxystrobin, DP Barcode: D228739. J. Arthur, 12/ 18/ 96). Non occupational postapplication risk in residential settings is covered in Section 5.2 The azoxystrobin technical material has been classified in Toxicity Category III for acute dermal and primary eye irritation, and Toxicity Category IV for primary skin irritation. Per the WPS, a 12 hr restricted entry interval ( REI) is required for chemicals classified under Toxicity Category III or IV, which is the shortest waiting period permitted under the WPS. However, per Pesticide Regulation Notice 95 3 ( 6/ 7/ 95, http:// www. epa. gov/ opppmsd1/ PR_ Notices/ pr95 3. html), REIs may be further reduced from 12 hours if certain criteria are met for both the technical material and the different EUPs. In a previous HED memorandum ( 10182 408, 10182 415. Response to Exposure SAC Review of Request to Add Residential Turf to Azoxystrobin Labels and to Reduce the Re Entry Interval to Four Hours, DP Barcode: D250401, P. Hurley, 10/ 28/ 98) HED determined that the criteria established by Pesticide Regulation Notice 95 3 for technical materials have been met for technical azoxystrobin. Furthermore, RD determined that the criteria for the EUPs Abound, Heritage and most recently Amistar ( Azoxystrobin 80WG EPA File Symbol 100 RAU, T. Keigwin, 2/ 27/ 03, D286344 and Azoxystrobin 80WG EPA File Symbol 100 RAU, T. Keigwin, 6/ 17/ 03, D288826) have been met for these azoxystrobin formulations. Therefore, a 4 hour REI is acceptable for those formulations. The only other azoxystrobin formulation considered in this document, A12910C, contains the active iingredient cyproconazole as well. Because cyproconazole does not meet all the criteria for a reduced REI, A12910C does not meet the reduced REI criteria either.

8.0 DATA NEEDS 8.1 Toxicology The HIARC determined that a 28 day inhalation toxicity study ( nose only) is required due to concern for occupational/ residential exposure via this route based on the current use pattern ( the 90 day protocol should be followed with an exposure duration of 28 days).

8.2 Residue Chemistry None 8.3 Occupational/ Residential 52 Label Requirements Heritage ® Fungicide  Residential Settings Label Amendment 1. The draft label specifies a solution concentration, but no definitive application rate is given. The label should specify the maximum application rate ( amount ai/ unit area).

2. The draft label directs the user to mix 0.26 fl. oz. ( 2 tablespoons) of product with 1 gallon of water; however, 1 fl. oz. is equivalent to 2 tablespoons, therefore, it would follow that 0.26 fl. oz. would be approximately 0.5 tablespoons ( or 1.5 teaspoons). The label should be modified to eliminate this discrepancy.

3. The azoxystrobin label that is currently registered for use indoors in residential settings ( Azoxystrobin Mold Retardant 2.08 SC) includes on the label use restrictions ( maximum application rate up to 3.3E 5 lb ai/ ft2, every 3 months as needed, but not to exceed 4 times per year). However, unlike the currently registered label, the Heritage label amendment specifies no use restrictions; the label states, " apply as needed, when regrowth or odors are observed or as a part of your cleaning routine." The Heritage label should be amended so it has use restrictions similar to the use restrictions on the Azoxystrobin Mold Retardant label.

Certain New Chemicals or Significant New Uses; Statements of
Findings for July 2019

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: Section 5(g) of the Toxic Substances Control Act (TSCA)
requires EPA to publish in the Federal Register a statement of its
findings after its review of TSCA section 5(a) notices when EPA makes a
finding that a new chemical substance or significant new use is not
likely to present an unreasonable risk of injury to health or the
environment. Such statements apply to premanufacture notices (PMNs),
microbial commercial activity notices (MCANs), and significant new use
notices (SNUNs) submitted to EPA under TSCA section 5. This document
presents statements of findings made by EPA on TSCA section 5(a)
notices during the period from July 1, 2019 to July 31, 2019.

FOR FURTHER INFORMATION CONTACT:
    For technical information contact: Greg Schweer, Chemical Control

0280. Please review the visitor instructions and additional information
about the docket available at http://www.epa.gov/dockets.

II. What action is the Agency taking?

    This document lists the statements of findings made by EPA after
review of notices submitted under TSCA section 5(a) that certain new
chemical substances or significant new uses are not likely to present
an unreasonable risk of injury to health or the environment. This
document presents statements of findings made by EPA during the period
from July 1, 2019 to July 31, 2019.

III. What is the Agency's authority for taking this action?

    TSCA section 5(a)(3) requires EPA to review a TSCA section 5(a)
notice and make one of the following specific findings:
     The chemical substance or significant new use presents an
unreasonable risk of injury to health or the environment;
     The information available to EPA is insufficient to permit
a reasoned evaluation of the health and environmental effects of the
chemical substance or significant new use;
     The information available to EPA is insufficient to permit
a reasoned evaluation of the health and environmental effects and the
chemical substance or significant new use may present an unreasonable
risk of injury to health or the environment;
     The chemical substance is or will be produced in
substantial quantities, and such substance either enters or may
reasonably be anticipated to enter the environment in substantial
quantities or there is or may be significant or substantial human
exposure to the substance; or
     The chemical substance or significant new use is not
likely to present an unreasonable risk of injury to health or the
environment.
    Unreasonable risk findings must be made without consideration of
costs or other non-risk factors, including an unreasonable risk to a
potentially exposed or susceptible subpopulation identified as relevant
under the conditions of use. The term ``conditions of use'' is defined
in TSCA section 3 to mean ``the circumstances, as determined by the
Administrator, under which a chemical substance is intended, known, or
reasonably foreseen to be manufactured, processed, distributed in
commerce, used, or disposed of.''
    EPA is required under TSCA section 5(g) to publish in the Federal
Register a statement of its findings after its review of a TSCA section
5(a) notice when EPA makes a finding that a new chemical substance or
significant new use is not likely to present an unreasonable risk of
injury to health or the environment. Such statements apply to PMNs,
MCANs, and SNUNs submitted to EPA under TSCA section 5.
    Anyone who plans to manufacture (which includes import) a new
chemical substance for a non-exempt commercial purpose and any
manufacturer or processor wishing to engage in a use of a chemical
substance designated by EPA as a significant new use must submit a
notice to EPA at least 90 days before commencing manufacture of the new
chemical substance or before engaging in the significant new use.
    The submitter of a notice to EPA for which EPA has made a finding
of ``not likely to present an unreasonable risk of injury to health or
the environment'' may commence manufacture of the chemical substance or
manufacture or processing for the significant new use notwithstanding
any remaining portion of the applicable review period.

IV. Statements of Administrator Findings Under TSCA Section 5(a)(3)(C)

    In this unit, EPA provides the following information (to the extent
that such information is not claimed as Confidential Business
Information

(CBI)) on the PMNs, MCANs and SNUNs for which, during this period, EPA
has made findings under TSCA section 5(a)(3)(C) that the new chemical
substances or significant new uses are not likely to present an
unreasonable risk of injury to health or the environment:
