                        ENVIRONMENTAL PROTECTION AGENCY

Emission Guidelines for Existing Other Solid Waste Incineration Units (40 CFR Part 60, Subpart FFFF) (Renewal)

1.  Identification of the Information Collection

      1(a)  Title of the Information Collection

Emission Guidelines for Existing Other Solid Waste Incineration Units (40 CFR Part 60,     Subpart FFFF) (Renewal), EPA ICR Number 2164.04, OPM Control Number 2060-0562

      1(b)  Short Characterization/Abstract

      Emission Guidelines for Existing Other Solid Waste Incineration Units (40 CFR Part 60, Subpart FFFF) were proposed on December 9, 2004 (69 FR 71471), promulgated on December 16, 2005 (70 FR 74892), and amended on November 24, 2006 (71 FR 67806).  The regulated OSWI units include two subcategories: very small municipal waste combustion (VSMWC) units that combust less that 35 tons per day of waste and institutional waste incineration (IWI) units. This standard applies to any air quality program in a state or United States protectorate with one or more existing other solid waste incineration (OSWI) units or air curtain incinerators that commenced construction on or before December 9, 2004.  This subpart does not directly affect incineration unit owners and operators; however, they must comply with the state's plan that was developed by the air quality program administrator to implement the emission guidelines.  This information is being collected to assure compliance with 40 CFR part 60, subpart FFFF.

      In general, all New Source Performance Standards (NSPS) require initial notifications, performance tests, one-time and periodic reports.  They are also required to maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative.  These notifications, reports and records are essential in determining compliance, and are required of all affected facilities subject to the NSPS.

      Any owners or operators subject to the provisions of this part shall maintain a file of these measurements, and retain the file for at least five years following the date of such measurements, maintenance reports, and records.  All reports are sent to the delegated state or local authority.       In the event that there is no such delegated authority, the reports are sent directly to the U. S. Environmental Protection Agency (EPA) regional office.

      Over the next three years, an average of 99 respondents per year will be subject to the standard, and no additional respondents will become subject to the standard.  This standard applies to OSWI units that commenced construction on or before December 9, 2004.  Therefore, there will be no new units constructed during the period covered by this ICR.

      The Office of Management and Budget (OMB) approved the currently active ICR without any "Terms of Clearance."

      All of the other solid waste incineration (OSWI) units in the United States, are owned and operated by the solid waste incineration industry (the "Affected Public").  However, this ICR applies directly to the emission guidelines with most of the units regulated by either, state, local, tribal or the Federal government.  They are considered not-for-profit businesses.  The burden to the "Affected Public" is listed below in Table 1: Annual Respondent Burden and Cost − Emission Guidelines for Existing Other Solid Waste Incineration Units (40 CFR Part 60, Subpart FFFF) (Renewal).  The Federal government burden associated with the review of reports submitted by the respondent is shown below in Table 2: Average Annual EPA Burden and Cost  -  Emission Guidelines for Existing Other Solid Waste Incineration Units (40 CFR Part 60, Subpart FFFF) (Renewal).

2.  Need for and Use of the Collection

      2(a)  Need/Authority for the Collection

      The EPA is charged under section 111(d)(1) of the Clean Air Act (CAA), as
amended, to:

            . . . prescribe regulations which shall establish a procedure similar to that provided by section 110 under which each State shall submit to the Administrator a plan which (A) establishes standards of performance for any existing source for any air pollutant (i) for which air quality criteria have not been issued or which is not included on a list published under section 108(a) . . . but (ii) to which a standard of performance under this section would apply if such existing source were a new source, and (B) provides for the implementation and enforcement of such standards of performance.

      The EPA is required under section 129 of the Act, to establish guidelines for existing stationary sources that reflect the maximum achievable control technology (MACT) for achieving continuous emission reductions:

      Section 129(a)(1)(A) states:

            The Administrator shall establish performance standards and other requirements pursuant to section 111 and this section for each category of solid waste incineration units.  Such standards shall include emissions limitations and other requirements applicable to new units and guidelines (under section 111(d) and this section) and other requirements applicable to existing units.

      Section 129(a)(2) states:

            Standards applicable to solid waste incineration units promulgated under section 111 and this section shall reflect the maximum degree of reduction in emissions of air pollutants listed under section (a)(4) that the Administrator, taking into consideration the cost of achieving such emission reduction, and any non-air quality health and environmental impacts and energy requirements, determines is achievable for new or existing units in each category.

      Section 129(b)(1) states:

            Performance standards under this section and section 111 for solid waste incineration units shall include guidelines promulgated pursuant to section 111(d) and this section applicable to existing units.  Such guidelines shall include, as provided in this section, each of the elements required by subsection (a) (emissions limitations, notwithstanding any restriction in section 111(d) regarding issuance of such limitations), subsection (c) (monitoring), subsection (d) (operator training), subsection (e) (permits), and subsection (h)(4) (residual risk).

      Subpart B of 40 CFR part 60 requires State plans to include monitoring, recordkeeping, and reporting provisions consistent with the emission guidelines.  In addition, section 114(a)(1) states that:

            the Administrator may require any person who owns or operates any emission source, who manufactures emission control equipment or process equipment, who the Administrator believes may have information necessary for the purposes set forth in this subsection, or who is subject to any requirement of this Act (other than a manufacturer subject to the provisions of section 206(c) or 208 with respect to a provision of title II) on a one-time, periodic or continuous basis to -

                  (A) establish and maintain such records;
                  (B) make such reports;
                  (C) install, use, and maintain such monitoring equipment, and use such audit procedures,
                  or methods;
                  (D) sample such emissions (in accordance with such procedures or methods, at such locations, at such intervals, during such periods and in such manner as the Administer shall prescribe);
                  (E) keep records on control equipment parameters, production variables or other indirect data when direct monitoring of emissions is impractical;
                  (F) submit compliance certifications in accordance with section 114(a)(3); and
                  (G) provide such other information, as the Administrator may reasonably require; . . . .

      In the Administrator's judgment, pollutant emissions from other solid waste incineration units cause or contribute to air pollution that may reasonably be anticipated to endanger public health or welfare.  Therefore, the emission guidelines were promulgated for this source category   at 40 CFR part 60, subpart FFFF.

      2(b)  Practical Utility/Users of the Data

      The recordkeeping and reporting requirements in the standard ensure compliance            with the applicable regulations, which were promulgated in accordance with the Clean                   Air Act.  The collected information is used also for targeting inspections and as evidence                 in legal proceedings.

      Performance tests are required in order to determine an affected facility's initial capability to comply with the emission standard.  Continuous emission monitors are used to ensure compliance with the standard at all times.  During the performance tests, a record of the operating parameters under which compliance was achieved may be recorded and used to determine compliance in place of a continuous emission monitor.

      The notifications required in the standard are used to inform the Agency or delegated authority when a source becomes subject to the requirements of the regulations.  The reviewing authority may then inspect the source to ensure that the pollution control devices are properly installed and operated, that leaks are being detected and repaired, and that the standards are being met.  The performance test may also be observed.

      The required semiannual reports are used to determine periods of excess emissions, identify problems at the facility, verify operation/maintenance procedures and for compliance determinations.

3.  Non-duplication, Consultations, and Other Collection Criteria

      The requested recordkeeping and reporting are required under 40 CFR part 60, subpart FFFF.

      3(a)  Non-duplication

      If the subject standards have not been delegated, the information is sent directly to the appropriate EPA regional office.  Otherwise, the information is sent directly to the delegated state or local agency.  If a state or local agency has adopted their own similar standards to implement the Federal standards, a copy of the report submitted to the state or local agency can be sent to the Administrator in lieu of the report required by the Federal standards.  Therefore, duplication does not exists.

      3(b)  Public Notice Required Prior to ICR Submission to OMB
      An announcement of a public comment period for the renewal of this ICR was published in the Federal Register (76 FR 26900) on May 9, 2011.  No comments were received on the burden published in the Federal Register.

      3(c)  Consultations

      The Agency has consulted industry experts and internal data sources to project the number of affected facilities and industry growth over the next three years.  The primary source of information as reported by industry, in compliance with the recordkeeping and reporting provisions in the standard, is the Online Tracking Information System (OTIS), which is operated and maintained by the EPA Office of Compliance.  OTIS is EPA's database for the collection, maintenance, and retrieval of all compliance data.  The growth rate for the industry is based on our consultations with the Agency's internal industry experts.

--------------------------------------------------------------------------------
      Industry trade associations and other interested parties were provided an opportunity to comment on the burden associated with the standard as it was being developed and the standard has been previously reviewed to determine the minimum information needed for compliance purposes.  In developing this ICR, we contacted: 1) the National Solid Waste Management Association (NSWMA), at<PHONE_NUMBER>; and 2) the Solid Waste Association of North America (SWANA), at<PHONE_NUMBER>. EPA did not receive any comments from the consultations.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      It is our policy to respond after a thorough review of comments received since the last ICR renewal as well as those submitted in response to the first Federal Register notice.
--------------------------------------------------------------------------------

      3(d)  Effects of Less Frequent Collection

      Less frequent information collection would decrease the margin of assurance that facilities are continuing to meet the standards.  Requirements for information gathering and recordkeeping are useful techniques to ensure that good operation and maintenance practices are applied and emission limitations are met.  If the information required by these standards were collected less frequently, the proper operation and maintenance of control equipment and the possibility of detecting violations would be less likely.

      3(e)  General Guidelines

      These reporting or recordkeeping requirements do not violate any of the regulations established by OMB at 5 CFR part 1320, section 1320.5.

      These standards require the respondents to maintain all records, including reports and notifications for at least five years.  This is consistent with the General Provisions as applied to the standards.  EPA believes that the five-year records retention requirement is consistent with the Part 70 permit program and the five-year statute of limitations on which the permit program is based.  The retention of records for five years allows EPA to establish the compliance history of a source, any pattern of non-compliance, and to determine the appropriate level of enforcement action.  EPA has found that the most flagrant violators have violations extending beyond the five years.              In addition, EPA would be prevented from pursuing the violators due to the destruction or nonexistence of essential records.

      3(f)  Confidentiality

      Any information submitted to the Agency for which a claim of confidentiality is made will be safeguarded according to the Agency policies set forth in title 40, chapter 1, part 2, subpart B - Confidentiality of Business Information (CBI) (see 40 CFR 2; 41 FR 36902, September 1, 1976; amended by 43 FR 40000, September 8, 1978; 43 FR 42251, September 20, 1978; 44 FR 17674, March 23, 1979).

      3(g)  Sensitive Questions

      The reporting or recordkeeping requirements in the standard do not include sensitive questions.

4.  The Respondents and the Information Requested

60.3010

Electronic Reporting

--------------------------------------------------------------------------------
      Some of the respondents are using monitoring equipment that automatically records parameter data.  Although personnel at the affected facility must still evaluate the data, internal automation has significantly reduced the burden associated with monitoring and recordkeeping at a plant site.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Also, regulatory agencies, in cooperation with the respondents continue to create reporting systems to transmit data electronically.  However, electronic reporting systems are not widely used.  At this time, it is estimated that 10 per	cent of the respondents use electronic reporting.
--------------------------------------------------------------------------------

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

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

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

--------------------------------------------------------------------------------
            (ii)  Respondent Activities

                             Respondent Activities
Read instructions.
Install, calibrate, maintain, and operate a coil coating line at their metal coil surface coating plants.
Perform initial performance test, Reference Methods, 3A, 3B, 26A tests, and repeat performance tests if necessary.
Write the notifications and reports listed above.
Enter information required to be recorded above.
Submit the required reports developing, acquiring, installing, and utilizing technology and systems for the purpose of collecting, validating, and verifying information.
Develop, acquire, install, and utilize technology and systems for the purpose of processing and maintaining information.
Develop, acquire, install, and utilize technology and systems for the purpose of disclosing and providing information.
Adjust the existing ways to comply with any previously applicable instructions and requirements.
Train personnel to be able to respond to a collection of information.
Transmit, or otherwise disclose the information.

	Currently, sources are using monitoring equipment that provides parameter data in an automated way (e.g., continuous parameter monitoring system).  Although personnel at the source still need to evaluate the data, this type of monitoring equipment has significantly reduced the burden associated with monitoring and recordkeeping.

5.  The Information Collected: Agency Activities, Collection Methodology, and Information Management

      5(a)  Agency Activities

      EPA conducts the following activities in connection with the acquisition, analysis, storage, and distribution of the required information.

                               Agency Activities
Observe initial performance tests and repeat performance tests if necessary.
Review notifications and reports, including performance test reports, excess emissions reports, required to be submitted by industry.
Audit facility records.
Input, analyze, and maintain data in the Online Tracking Information System (OTIS).

      5(b)  Collection Methodology and Management

Following notification of startup, the reviewing authority could inspect the source to determine whether the pollution control devices are properly installed and operational.  Performance test reports are used by the Agency to discern a source's initial capability to comply with the emission standard, and note the operating conditions under which compliance was achieved.        Data and records maintained by the respondents are tabulated and published for use in compliance and enforcement programs.  The semiannual reports are used for problem identification, as a check on source operation and maintenance, and for compliance determinations.

      Information contained in the reports is entered into OTIS, which is operated and maintained by the EPA Office of Compliance.  OTIS is EPA's database for the collection, maintenance, and retrieval of compliance data for approximately 125,000 industrial and government-owned facilities.  EPA uses OTIS for tracking air pollution compliance and enforcement by local and state regulatory agencies, EPA regional offices, and EPA headquarters.  EPA and its delegated Authorities can edit, store, retrieve and analyze the data.

      The records required by this regulation must be retained by the owner or operator for five years.

      5(c)  Small Entity Flexibility

--------------------------------------------------------------------------------
      The majority of the respondents are large entities (i.e., large businesses).  However,          the impact on small entities (i.e., small businesses) was taken into consideration during the development of the regulation.  Due to technical considerations, involving the process operations and the types of control equipment employed, the recordkeeping and reporting requirements are the same for both small and large entities.  The Agency considers these the minimum requirements needed to ensure compliance and, therefore, cannot reduce them further for small entities.  To the extent that larger businesses can use economies of scale to reduce their burden, the overall burden will be reduced.

      5(d)  Collection Schedule

      The specific frequency for each information collection activity within this request is shown below in Table 1: Annual Respondent Burden and Cost − Emission Guidelines for Existing Other Solid Waste Incineration Units (40 CFR Part 60, Subpart FFFF) (Renewal).

6.  Estimating the Burden and Cost of the Collection

      Table 1 documents the computation of individual burdens for the recordkeeping and reporting requirements applicable to the industry for the subpart included in this ICR.  The individual burdens are expressed under standardized headings believed to be consistent with the concept of burden under the Paperwork Reduction Act.  Wherever appropriate, specific tasks and major assumptions have been identified.  Responses to this information collection are mandatory.

      The Agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB Control Number.

      6(a)  Estimating Respondent Burden

      The average annual burden to industry over the next three years from these recordkeeping and reporting requirements is estimated to be 70,132 (Total Labor Hours from Table 1 below).  These hours are based on Agency studies and background documents from the development of the regulation, Agency knowledge and experience with the NSPS program, the previously-approved ICR, and any comments received.

      6(b)  Estimating Respondent Costs

            (i)  Estimating Labor Costs

	This ICR uses the following labor rates:

            Managerial 	$121.42 ($57.82 + 110%)
            Technical	$99.14 ($47.21 + 110%)
            Clerical	$49.81 ($23.27 + 110%)

These rates are from the United States Department of Labor, Bureau of Labor Statistics, September 2011 "Table 2: Civilian Workers, by occupational and industry group."  The rates are from column 1, "Total Compensation."  The rates have been increased by 110 percent to account for the benefit packages available to those employed by private industry.

            (ii)  Estimating Capital/Startup and Operation and Maintenance Costs

      The type of industry costs associated with the information collection activities in the subject standard are both labor costs, which are addressed elsewhere in this ICR, and the costs associated with continuous monitoring.  The capital/startup costs are one-time costs when a facility becomes subject to the regulation.  The annual operation and maintenance costs are the ongoing costs to maintain the monitor and other costs, such as photocopying and postage.

            (iii)  Capital/Startup vs. Operation and Maintenance (O&M) Costs

      The total capital/startup costs for this ICR are zero.  This is the total of column D in the above table.

--------------------------------------------------------------------------------
      The total operation and maintenance (O&M) costs are $495,000.  This is the total of column G.

      The average annual cost for capital/startup and operation and maintenance costs to industry over the next three years of the ICR is estimated to be $495,000.

      6(c)  Estimating Agency Burden and Cost

--------------------------------------------------------------------------------
      The only costs to the Agency are those costs associated with analysis of the reported information.  EPA's overall compliance and enforcement program includes activities such as the examination of records maintained by the respondents, periodic inspection of sources of emissions, and the publication and distribution of collected information.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The average annual Agency cost during the three years of the ICR is estimated to be $389,912.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      This cost is based on the average hourly labor rate as follows:
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            Managerial	$62.27   (GS-13, Step 5, $38.92 + 60%)
--------------------------------------------------------------------------------
            Technical	$46.21   (GS-12, Step 1, $28.88 + 60%)
--------------------------------------------------------------------------------
            Clerical	$25.01   (GS-6, Step 3, $15.63 + 60%)
--------------------------------------------------------------------------------

      These rates are from the Office of Personnel Management (OPM), 2011 General Schedule, which excludes locality rates of pay.  The rates have been increased by 60 percent to account for the benefit packages available to government employees.  Details upon which this estimate is based appear below in Table 2: Average Annual EPA Burden and Cost − Emission Guidelines for Existing Other Solid Waste Incineration Units (40 CFR Part 60, Subpart FFFF) (Renewal).
--------------------------------------------------------------------------------

      6(d)  Estimating the Respondent Universe and Total Burden and Costs

	Based on our research for this ICR, on average over the next three years, approximately 99 existing respondents will be subject to the standard.  It is estimated that no additional respondents per year will become subject to the standard.  The average number of respondents, as shown in the table below, is 99 per year.

	The number of respondents is calculated using the following table that addresses the three years covered by this ICR.

      6(e)  Bottom Line Burden Hours Burden Hours and Cost Tables

--------------------------------------------------------------------------------
      The detailed bottom line burden hours and cost calculations for the respondents and the Agency are shown in Tables 1 and 2, respectively, and summarized below.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            (i)  Respondent Tally

      The total annual labor hours are 70,132, at a cost of $6,720,028.  Details regarding these estimates may be found below in Table 1: Annual Respondent Burden and Cost − Emission Guidelines for Existing Other Solid Waste Incineration Units (40 CFR Part 60, Subpart FFFF) (Renewal).

      Furthermore, the annual public reporting and recordkeeping burden for this collection       of information is estimated to average 236 hours per response.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The total annual capital/startup and O&M costs to the regulated entity are $495,000.       The cost calculations are detailed in Section 6(b)(iii), Capital/Startup vs. Operation and Maintenance (O&M) Costs.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            (ii)  The Agency Tally
--------------------------------------------------------------------------------

      The average annual Agency burden and cost over next three years is estimated to be 8,653 labor hours, at a cost of $389,912.  See below Table 2: Average Annual EPA Burden and Cost − Emission Guidelines for Existing Other Solid Waste Incineration Units (40 CFR Part 60, Subpart FFFF) (Renewal).

      6(f)  Reasons for Change in Burden

      There is a decrease in the total estimated burden for both the respondents and the Agency from the most recently approved ICR due to a decrease in the number of sources.  At the time of rule promulgation, EPA estimated that 248 respondents were subject to the standard.  However, many facilities have shut down or ceased operation since 2005.  In recent years in support of potential OSWI regulatory development, the Agency consulted with internal data experts and conducted data and permits searches to inventory the number of existing OSWI units. The data collection activities in 2010 suggest that only 99 VSMWC and IWI sources are subject to the standard.  This represents an approximately 60 percent decrease in the respondent universe since 2005.

      The decrease in the respondent universe also results in significant reduction of the overall O&M costs to the respondents.

      Additionally, this ICR corrects a mathematical error in the previous ICR's estimate for the respondent recordkeeping burden.

      6(g)  Burden Statement

      The annual public reporting and recordkeeping burden for this collection of information is estimated to average 236 hours per response.  Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, disclose or provide information to or for a Federal agency.  This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information.

--------------------------------------------------------------------------------
      An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a valid OMB Control Number.  The OMB Control Numbers for EPA's regulations are listed at 40 CFR part 9 and 48 CFR chapter 15.

      To comment on the Agency's need for this information, the accuracy of the provided burden estimates, and any suggested methods for minimizing respondent burden, including the use of automated collection techniques, EPA has established a public docket for this ICR under Docket ID Number EPA-HQ-OECA-2011-0256.

Assumptions:
[a]  We have assumed that there are approximately 99 respondents, with no additional new or reconstructed sources becoming subject to the rule over the next three years.
[b]  This ICR uses the following labor rates:  $121.42 per hour for Executive, Administrative, and Managerial labor; $99.14 per hour for Technical labor, and $49.81 per hour for Clerical labor.  These rates are from the United States Department of Labor, Bureau of Labor Statistics, September 2011 "Table 2: Civilian Workers, by occupational and industry group."  The rates are from column 1, "Total Compensation."  The rates have been increased by 110 percent to account for the benefit packages available to those employed by private industry.
[c]  We have assumed that this is a one-time only cost.
[d]  This is the fifth year when a respondent will have reached the compliant date for the emission guidelines.
[e]  We have assumed that 20 percent of respondents will repeat initial tests due to failure.
f  We have assumed that RATA audits are performed for one of the four quarterly audits, and RAA tests are performed for three of the four quarterly audits.
g  We have assumed that each operation day requires a CEMS calibration; Combustor models 2, 3, and 4 assume 250 days of operation per year, Model 1 = 121 days/yr.  For consistency, 250 operating days are assumed for all models.  Emission testing hours (0.25 hr/occurrence) accounts for periodic contractor operation and maintenance support.  Annual hours averaged to a daily basis.
h  We have assumed that each respondent will record information 52 times per year.

DEPARTMENT OF ENERGY

Federal Energy Regulatory Commission

[Docket No. CP13-83-000]

Arlington Storage Company, LLC; Notice of Availability of the
Environmental Assessment for the Proposed Gallery 2 Expansion Project

    The staff of the Federal Energy Regulatory Commission (FERC or
Commission) has prepared an environmental assessment (EA) for the
Gallery 2 Expansion Project, proposed by Arlington Storage Company, LLC
(Arlington) in the above-referenced docket. Arlington requests
authorization to convert two existing salt caverns, known as Gallery 2,
to natural gas storage at its Seneca Lake Storage facility in Schuyler
County, New York. The conversion of the Gallery 2 caverns to natural
gas storage would add 0.55 billion cubic feet (Bcf) of working gas
capacity, and 0.20 Bcf of base gas capacity to the Seneca Lake Storage
facility, increasing the total working gas capacity from 1.45 Bcf to
2.0 Bcf.
    The EA assesses the potential environmental effects of the
construction and operation of the Gallery 2 Expansion Project in
accordance with the requirements of the National Environmental Policy
Act (NEPA) of 1969. The FERC staff concludes that approval of the
proposed

project, with appropriate mitigating measures, would not constitute a
major federal action significantly affecting the quality of the human
environment.
    The New York State Department of Environmental Conservation
participated as a cooperating agency in the preparation of the EA.
Cooperating agencies have jurisdiction by law or special expertise with
respect to resources potentially affected by the proposal and
participate in the NEPA analysis.
    In addition to the two existing salt caverns previously used for
liquefied petroleum gas (LPG) storage, the proposed Gallery 2 Expansion
Project includes the following facilities:
     Approximately 500 feet of pipeline (170 feet of 16-inch-
diameter and 330 feet of 8-inch-diameter pipeline) to connect the
Gallery 2 injection/withdrawal wells 30A and 31A to Arlington's
existing Seneca Lake 16-inch-diameter natural gas pipeline;
     A 500 horsepower skid-mounted compressor unit;
     Use of well no. 45 for debrining and future monitoring of
the caverns;
     A temporary brine pump and temporary brine pipelines;
     Electric and instrument air lines connecting the Gallery 2
facilities to Arlington's existing Compressor Station; and
     Plugging and abandonment of two existing wells (30 and 31)
formerly used in the Gallery 2 caverns' brine production and liquefied
petroleum gas storage operation.
    The FERC staff mailed copies of the EA to federal, state, and local
government representatives and agencies; elected officials;
environmental and public interest groups; Native American tribes;
potentially affected landowners and other interested individuals and
groups; newspapers and libraries in the project area; and parties to
this proceeding. In addition, the EA is available for public viewing on
the FERC's Web site (www.ferc.gov) using the eLibrary link. A limited
number of copies of the EA are available for distribution and public
inspection at: Federal Energy Regulatory Commission, Public Reference
Room, 888 First Street NE., Room 2A, Washington, DC 20426, (202) 502-
8371.

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2020-0494; Project Identifier AD-2020-00324-E]
RIN 2120-AA64

Airworthiness Directives; General Electric Company Turbofan
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for all General Electric Company (GE) GE90-110B1 and GE90-115B model
turbofan engines with a certain high-pressure turbine (HPT) rotor stage
2 disk installed. This proposed AD was prompted by a report from the
manufacturer that a subsurface anomaly was found on a HPT rotor stage 2
disk. This proposed AD would require an ultrasonic inspection (USI) of
the HPT rotor stage 2 disk and, depending on the result of the
inspection, replacement of the HPT rotor stage 2 disk with a part
eligible for installation. The FAA is proposing this AD to address the
unsafe condition on these products.

SUPPLEMENTARY INFORMATION:

Comments Invited

    The FAA invites you to send any written relevant data, views, or
arguments about this proposal. Send your comments to an address listed
under the ADDRESSES section. Include ``Docket No. FAA-2020-0494;
Project Identifier AD-2020-00324-E'' at the beginning of your comments.
The FAA specifically invites comments on the overall regulatory,
economic, environmental, and energy aspects of this NPRM. The FAA will
consider all comments received by the closing date and may amend this
NPRM because of those comments.
    Except for Confidential Business Information (CBI) as described in
the following paragraph, and other information as described in 14 CFR
11.35, the FAA will post all comments received, without change, to
https://www.regulations.gov, including any personal information you
provide. The FAA will also post a report summarizing each substantive
verbal contact received about this NPRM.

Confidential Business Information

    Confidential Business Information (CBI) is commercial or financial
information that is both customarily and actually treated as private by
its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552),
CBI is exempt from public disclosure. If your comments responsive to
this AD contain commercial or financial information that is customarily
treated as private, that you actually treat as private, and that is
relevant or responsive to this AD, it is important that you clearly
designate the submitted comments as CBI. Please mark each page of your
submission containing CBI as ``PROPIN.'' The FAA will treat such marked
submissions as confidential under the FOIA, and they will not be placed
in the public docket of this AD. Submissions containing CBI should be
sent to Stephen Elwin, Aerospace Engineer, ECO Branch, FAA, 1200
District Avenue, Burlington, MA, 01803. Any commentary that the FAA
receives which is not specifically designated as CBI will be placed in
the public docket for this rulemaking.

Discussion

    The FAA received a report from the manufacturer that a subsurface
anomaly was found on a HPT rotor stage 2 disk. The manufacturer
determined that the subsurface anomaly developed during the material
melting process. This condition, if not addressed, could result in
uncontained HPT rotor stage 2 disk release, damage to the engine, and
damage to the airplane.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed GE GE90-100 Service Bulletin (SB) 72-0838, dated
January 31, 2020. The SB describes procedures for performing an USI of
the HPT rotor stage 2 disk. This service information is reasonably
available because the interested parties have access to it through
their normal course of business or by the means identified in the
ADDRESSES section.

FAA's Determination

    The FAA is proposing this AD because it evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require an USI of the HPT rotor stage 2 disk
and, depending on the results of the inspection, replacement of the HPT
rotor stage 2 disk with a part eligible for installation.

Costs of Compliance

    The FAA estimates that this proposed AD affects 12 engines
installed on airplanes of U.S. registry.

    The FAA estimates the following costs to comply with this proposed
AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                Cost per       Cost on U.S.
               Action                        Labor cost           Parts cost        product         operators

                                       hour = $680.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary
replacements that would be required based on the results of the
proposed inspection. The FAA has no way of determining the number of
engines that might need this replacement:

                                               On-Condition Costs

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

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.
    The FAA is 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

    The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would not
have a substantial direct effect on the States, on the relationship
between the national Government and the States, or on the distribution
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed
regulation:
    (1) Is not a ``significant regulatory action'' under Executive
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES
