FERC-604, Cash Management Agreements

    OMB Control No.: 1902-0267.
    Abstract: Cash management or ``money pool'' programs typically
concentrate affiliates' cash assets in joint accounts for the purpose
of providing financial flexibility and lowering the cost of borrowing.
    In a 2001 investigation, FERC staff found that balances in cash
management programs affecting FERC-regulated entities totaled
approximately $16 billion. Additionally, other investigations revealed
large transfers of funds (amounting to more than $1 billion) between
regulated pipeline affiliates and non-regulated parents whose financial
conditions were precarious. The Commission found that these and other
fund transfers and the

enormous (mostly unregulated) pools of money in cash management
programs could detrimentally affect regulated rates.
    To protect customers and promote transparency, the Commission
issued Order 634-A (2003) requiring entities to formalize in writing
and file with the Commission their cash management agreements. At that
time, the Commission obtained OMB clearance for this new reporting
requirement under the FERC-555 information collection (OMB Control No.
1902-0098). Now, the Commission includes these reporting requirements
for cash management agreements under the FERC-604 information
collection (OMB Control No. 1902-0267). The Commission implemented
these reporting requirements in 18 CFR parts 141.500, 260.400, and
357.5.
    Type of Respondent: Public utilities, natural gas companies, and
oil pipeline companies.
    Estimate of Annual Burden: The Commission estimates the annual
public reporting burden for the information collection as:
---------------------------------------------------------------------------

    \1\ The estimates for cost per response are derived using the
following formula: Average Burden Hours per Response * $74.50 per
Hour = Average Cost per Response. The Commission staff believes that
the industry's level and skill set is comparable to FERC's with an
average hourly cost (wages plus benefits) of $74.50.

FERC-923, Communication of Operational Information Between Natural Gas
Pipelines and Electric Transmission Operators

    OMB Control No.: 1902-0265.
    Abstract: In 2013, the Federal Energy Regulatory Commission (FERC
or Commission) revised its regulations to provide explicit authority to
interstate natural gas pipelines and public utilities that own,
operate, or control facilities used for the transmission of electric
energy in interstate commerce to voluntarily share non-public,
operational information with each other for the purpose of promoting
reliable service and operational planning on either the pipeline's or
public utility's system. This helps ensure the reliability of natural
gas pipeline and public utility transmission service by permitting
transmission operators to share the information with each other that
they deem necessary to promote the reliability and integrity of their
systems. FERC removed actual or perceived prohibitions to the
information sharing and communications between industry entities. The
communications of information are not and will not be submitted to
FERC. Rather, the non-public information is shared voluntarily between
industry entities. FERC does not prescribe the content, medium, format,
or frequency for the information sharing and communications. Those
decisions are made by the industry entities, depending on their needs
and the situation.
    Type of Respondent: Natural gas pipelines and public utilities.
    Estimate of Annual Burden: The Commission estimates the annual
public reporting burden for the information collection as:
---------------------------------------------------------------------------

    \2\ The estimates for cost per response are derived using the
following formula: Average Burden Hours per Response * $74.50 per
Hour = Average Cost per Response. The Commission staff believes that
the industry's level and skill set is comparable to FERC's with an
average hourly cost (wages plus benefits) of $74.50.
    \3\ The estimate for the number of respondents is based on the
North American Electric Reliability Corporation (NERC) Compliance
Registry as of July 29, 2016, minus the Transmission Operators
within ERCOT.

 BILLING CODE 6717-01-P


not likely to have a significant adverse effect on the supply,
distribution or use of energy and has not otherwise been designated by
the Administrator of the Office of Information and Regulatory Affairs
as a significant energy action. This is a national drinking water
occurrence study that was submitted to OMB for review.

I. National Technology Transfer and Advancement Act (NTTAA)

    This action involves technical standards. EPA has identified
options that involve using analytical methods developed by the agency
and three major voluntary consensus method organizations to support
UCMR 5 monitoring. The voluntary consensus method organizations are
Standard Methods for the Examination of Water and Wastewater, and ASTM
International. EPA identified acceptable consensus method organization
standards for the analysis of lithium. A summary of each method along
with how the method specifically applies to UCMR 5 can be found in
Section III.I of this preamble.
    All of these standards are reasonably available for public use. EPA
methods are free for download on the agency's website. The methods in
the Standard Methods for the Examination of Water and Wastewater 23rd
edition are consensus standards, available for purchase from the
publisher, and are commonly used by the drinking water laboratory
community. The methods in the Standard Methods Online are consensus
standards, available for purchase from the publisher's website, and are
commonly used by the drinking water laboratory community. The methods
from ASTM International are consensus standards, are available for
purchase from the publisher's website, and are commonly used by the
drinking water laboratory community.

J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations

    EPA believes that this action is not subject to Executive Order
12898 (59 FR 7629, February 16, 1994) because it does not establish an
environmental health or safety standard. Background information
regarding EPA's consideration of Executive Order 12898 in the
development of this final rule is provided in Section III.F of this
preamble, and an additional supporting document, titled, ``Summary of
Environmental Justice Considerations for the Fifth Unregulated
Contaminant Monitoring Rule (UCMR 5) Proposal,'' has been placed in the
electronic docket listed in the ADDRESSES section of this preamble.

K. Congressional Review Act (CRA)

    This action is subject to the CRA, and EPA will submit a rule
report to each House of the Congress and to the Comptroller General of
the United States. This action is not a ``major rule'' as defined by 5
U.S.C. 804(2).

(c)(5)(i), and (c)(6)(ii);
0
d. In paragraph (d)(2), revise the first, second, and third sentences;
and
0
f. Revise paragraph (e).
    The revisions read as follows:

Sec.  141.35   Reporting for unregulated contaminant monitoring
results.

    (a) * * * For the purposes of this section, PWS ``population
served'' is the retail population served directly by the PWS as
reported to the Federal Safe Drinking Water Information System (SDWIS/
Fed). * * *
* * * * *
    (c) * * *
    (2) Sampling location inventory information. You must provide your
inventory information by December 31, 2022, using EPA's electronic data
reporting system, as specified in paragraph (b)(1) of this section. You
must submit, verify, or update data elements 1-9 (as defined in Table 1
of paragraph (e) of this section) for each sampling location, or for
each approved representative sampling location (as specified in
paragraph (c)(3) of this section) regarding representative sampling
locations. If this information changes, you must report updates,
including new sources, and sampling locations that are put in use
before or during the UCMR sampling period, to EPA's electronic data
reporting system within 30 days of the change.
    (3) * * *
    (i) Qualifications. Large PWSs that have EPA- or State-approved
representative EPTDS sampling locations from a previous UCMR cycle, or
as provided for under 40 CFR 141.23(a)(1), 40 CFR 141.24(f)(1), or 40
CFR 141.24(h)(1), may submit a copy of documentation from your State or
EPA that approves your representative sampling plan. PWSs that do not
have an approved representative EPTDS sampling plan may submit a
proposal to sample at representative EPTDS(s) rather than at each
individual EPTDS if: You use ground water as a source; all of your well
sources have either the same treatment or no treatment; and you have
multiple EPTDSs from the same source (i.e., same aquifer). You must
submit a copy of the existing or proposed representative EPTDS sampling
plan, as appropriate, at least six months prior to your scheduled
sample collection, as specified in paragraph (b)(1) of this section. If
changes to your inventory that impact your representative plan occur
before or during the UCMR sampling period, you must report updates
within 30 days of the change.

    (ii) Demonstration. If you are submitting a proposal to sample at
representative EPTDS(s) rather than at each individual EPTDS, you must
demonstrate that any EPTDS that you propose as representative of
multiple wells is associated with a well that draws from the same
aquifer as the wells it will represent. The proposed well must be
representative of the highest annual volume and most consistently
active wells in the representative array. If that representative well
is not in use at the scheduled sampling time, you must select and
sample an alternative representative well. You must submit the
information defined in Table 1, paragraph (e) of this section for each
proposed representative sampling location. You must also include
documentation to support your proposal that the specified wells are
representative of other wells. This documentation can include system-
maintained well logs or construction drawings indicating that the
representative well(s) is/are at a representative depth, and details of
well casings and grouting; data demonstrating relative homogeneity of
water quality constituents (e.g., pH, dissolved oxygen, conductivity,
iron, manganese) in samples drawn from each well; and data showing that
your wells are located in a limited geographic area (e.g., all wells
within a 0.5 mile radius) and/or, if available, the hydrogeologic data
indicating the ground water travel time between the representative well
and each of the individual wells it represents (e.g., all wells within
a five-year time of travel delineation). Your proposal must be sent in
writing to EPA, as specified in paragraph (b)(1) of this section.
    (iii) Approval. EPA or the State (as specified in the Partnership
Agreement reached between the State and EPA) will review your proposal
and coordinate any necessary changes with you. Your plan will not be
final until you receive written approval from EPA, identifying the
final list of EPTDSs where you will be required to monitor.
    (4) Contacting EPA if your PWS has not been notified of
requirements. If you believe you are subject to UCMR requirements, as
defined in 40 CFR 141.40(a)(1) and (a)(2)(i), and you have not been
contacted by either EPA or your State by April 26, 2022, you must send
a letter to EPA, as specified in paragraph (b)(1) of this section. The
letter must be from your PWS Official and must include an explanation
as to why the UCMR requirements are applicable to your system along
with the appropriate contact information. A copy of the letter must
also be submitted to the State as directed by the State. EPA will make
an applicability determination based on your letter, and in
consultation with the State when necessary and will notify you
regarding your applicability status and required sampling schedule.
However, if your PWS meets the applicability criteria specified in 40
CFR 141.40(a)(2)(i), you are subject to the UCMR monitoring and
reporting requirements, regardless of whether you have been contacted
by the State or EPA.
    (5) * * *
    (i) General rescheduling notification requirements. Large systems
may independently change their monitoring schedules up to December 31,
2022, using EPA's electronic data reporting system, as specified in
paragraph (b)(1) of this section. After this date has passed, if your
PWS cannot sample according to your assigned sampling schedule (e.g.,
because of budget constraints, or if a sampling location will be closed
during the scheduled month of monitoring), you must mail or email a
letter to EPA, as specified in paragraph (b)(1) of this section, prior
to the scheduled sampling date. You must include an explanation of why
the samples cannot be taken according to the assigned schedule, and you
must provide the alternative schedule you are requesting. You must not
reschedule monitoring specifically to avoid sample collection during a
suspected vulnerable period. You are subject to your assigned UCMR
sampling schedule or the schedule that you revised on or before
December 31, 2022, unless and until you receive a letter from EPA
specifying a new schedule.
* * * * *
    (6) * * *
    (ii) Reporting schedule. You must require your laboratory, on your
behalf, to post and approve the data in EPA's electronic data reporting
system, accessible at https://www.epa.gov/dwucmr, for your review
within 90 days from the sample collection date (sample collection must
occur as specified in 40 CFR 141.40(a)(4)). You then have 30 days from
when the laboratory posts and approves your data to review, approve,
and submit the data to the State and EPA via the agency's electronic
data reporting system. If you do not electronically approve and submit
the laboratory data to EPA within 30 days of the laboratory posting
approved data, the data will be considered approved by you and
available for State and EPA review.
* * * * *
    (d) * * *
    (2) Sampling location inventory information. You must provide your
inventory information by December 31, 2022, using EPA's electronic data
reporting system, as specified in paragraph (b)(1) of this section. If
this information changes, you must report updates, including new
sources, and sampling locations that are put in use before or during
the UCMR sampling period, to EPA's electronic data reporting system
within 30 days of the change, as specified in paragraph (b)(1) of this
section. * * *
    (e) Data elements. Table 1 defines the data elements that must be
provided for UCMR monitoring.

Column headings are:
1--Contaminant: The name of the contaminant to be analyzed.
2--CASRN (Chemical Abstracts Service Registry Number) or Identification Number: A unique number identifying the chemical contaminants.
3--Analytical Methods: Method numbers identifying the methods that must be used to test the contaminants.
4--Minimum Reporting Level (MRL): The value and unit of measure at or above which the concentration of the contaminant must be measured using the
  approved analytical methods. If EPA determines, after the first six months of monitoring that the specified MRLs result in excessive resampling, EPA
  will establish alternate MRLs and will notify affected PWSs and laboratories of the new MRLs. N/A is defined as non-applicable.
5--Sampling Location: The locations within a PWS at which samples must be collected.
6--Period During Which Sample Collection to be Completed: The time period during which the sampling and testing will occur for the indicated
  contaminant.
\a\ The analytical procedures shall be performed in accordance with the documents associated with each method, see paragraph (c) of this section.
\b\ The MRL is the minimum concentration of each analyte that must be reported to EPA.
\c\ Sampling must occur at your PWS's entry points to the distribution system (EPTDSs), after treatment is applied, that represent each non-emergency
  water source in routine use over the 12-month period of monitoring. Systems that purchase water with multiple connections from the same wholesaler may
  select one representative connection from that wholesaler. The representative EPTDS must be a location within the purchaser's water system. This EPTDS
  sampling location must be representative of the highest annual volume connections. If the connection selected as the representative EPTDS is not
  available for sampling, an alternate highest volume representative connection must be sampled. See 40 CFR 141.35(c)(3) for an explanation of the
  requirements related to the use of representative GW EPTDSs.

    (i) * * *
    (A) Sample collection period. You must collect the samples in one
continuous 12-month period for List 1 Assessment Monitoring, and, if
applicable, for List 2 Screening Survey, or List 3 Pre-Screen Testing,
during the timeframe indicated in column 6 of table 1 to paragraph
(a)(3) of this section. EPA or your State will specify the month(s) and
year(s) in which your monitoring must occur. As specified in 40 CFR
141.35(c)(5), you must contact EPA if you believe you cannot collect
samples according to your schedule.
    (B) Frequency. You must collect the samples within the timeframe
and according to the frequency specified by contaminant type and water
source type for each sampling location, as specified in table 2 to this
paragraph (a)(4)(i)(B). For the second or subsequent round of sampling,
if a sample location is non-operational for more than one month before
and one month after the scheduled sampling month (i.e., it is not
possible for you to sample within the window specified in table 2), you
must notify EPA as specified in 40 CFR 141.35(c)(5) to reschedule your
sampling.
