Dear Mr. Yousif:
In a July 19, 2019, letter to the Pipeline and Hazardous Materials Safety Administration
(PHMSA), you asked whether the Iowa Utilities Board (Board) has the authority to grant a
deviation from the atmospheric corrosion inspection frequency requirements in 49 CFR
§192.481, as provided for in §192.1013.
In your letter, you provided that on June 16, 2017, Alliant Energy-Interstate Power and Light
Company (IPL) filed a request with the Board to revise its atmospheric corrosion inspection
frequency for its gas distribution system. If granted, you stated that IPL requested approval to
deviate from the periodic inspection requirements of§ 192.481 by performing atmospheric
corrosion inspections from at least once every three calendar years, but with intervals not
exceeding 39 months to at least once every four calendar years, but with intervals not exceeding
51 months. You further stated, that IPL also proposed to maintain or improve safety by
accelerating the frequency of distribution system leak surveys from every five years to every four
years.
According to your letter, IPL filed a response with the Board on May 6, 2019, clarifying that it
sought a deviation to inspection intervals under 49 CFR §192.1013. You stated that IPL noted
that § 192.1013 allows the Board to accept a pipeline operator's proposal to reduce the frequency
of periodic inspections under its own authority. In response to this clarification, the Board issued
an "Order Addressing Waiver and Directing Letter to the Pipeline and Hazardous Materials
Safety Administration" on June 27, 2019, directing Board staff to send a letter to PHMSA
requesting a response regarding the authority of the Board to grant a deviation pursuant to
§192.1013. You stated that the Board wants to ensure the approved waiver does not violate its
agreement with PHMSA, nor does the Board want to require IPL to comply with conditions that
may not be necessary for the deviation in the frequency of periodic inspections.
Section 192.1013 states:
The Pipeline and Hazardous Materials Safety Administration, Office of Pipeline Safety provides written clarifications of the Regulations (49 CFR
Parts 190-199) in the form of interpretation letters. These letters reflect the agency's current application of the regulations to the specific facts
presented by the person requesting the clarification. Interpretations do not create legally-enforceable rights or obligations and are provided to
help the public understand how to comply with the regulations.

§ 192.1013 When may an operator deviate from required periodic inspections under this
part?
(a) An operator may propose to reduce the frequency of periodic inspections and tests
required in this part on the basis of the engineering analysis and risk assessment required
by this subpart.
(b) An operator must submit its proposal to the PHMSA Associate Administrator for
Pipeline Safety or, in the case of an intrastate pipeline facility regulated by the State, the
appropriate State agency. The applicable oversight agency may accept the proposal on its
own authority, with or without conditions and limitations, on a showing that the
operator's proposal, which includes the adjusted interval, will provide an equal or greater
overall level of safety.
( c) An operator may implement an approved reduction in the frequency of a periodic
inspection or test only where the operator has developed and implemented an integrity
management program that provides an equal or improved overall level of safety despite
the reduced frequency of periodic inspections.
First, the regulations in subpart P of part 192, including §192.1013, prescribe the minimum
requirements for a gas distribution integrity management program (DIMP). In connection with
an operator's DIMP, § 192.1013 ( a) is clear in allowing an operator to propose a reduction in the
frequency of inspections and tests required in part 192, provided that the operator completes an
engineering analysis and risk assessment required by subpart P and ensures an equivalent or
improved level of safety through its DIMP. Second, §192.1013(b) specifies that such a proposal
must be submitted to PHMSA or the appropriate State agency. In the present case, the Board
may accept IPL's proposal on its own authority, with or without conditions or limitations, on a
showing that IPL's proposal will provide an equal or greater level of safety and otherwise
complies with§ 192.1013. Third, PHMSA's review of the Board's acceptance of any such
proposal is not required, differentiating it from the requirements of 49 USC 60118(d).
Therefore, it is PHMSA's interpretation that as the appropriate State agency for the intrastate
pipeline, the Board may accept or deny ILP's proposal on its own authority in accordance with
§192.1013(b).

Dear Mr. Mayberry,
On June 16, 2017, Alliant Energy-Interstate Power and Light Company (IPL) filed a
request with the Iowa Utilities Board (Board) to revise its atmospheric corrosion
inspection frequency. IPL requested permission to deviate from the periodic inspection
requirements contained in 49 CFR 192.481. In the request, IPL sought approval to
perform atmospheric corrosion inspections at least once every four calendar years, but
with intervals not exceeding 51 months. At the same time, to maintain or improve
safety, IPL will accelerate the frequency of distribution system leak surveys from every
five years to every four years.
The Board is the agency responsible for administering the pipeline safety programs of
the State of Iowa, and for enforcement of the natural gas pipeline safety standards of 49
CFR Parts 192, 193 and 199 under certification granted by the U.S. Department of
Transportation (DOT) pursuant to 49 U.S.C.S. 60105. Under 49 U.S.C. § 60118(d), the
Board must provide the Pipeline and Hazardous Materials Safety Administration
(PHMSA) with written notice of the waiver and allow at least 60 days for PHMSA review
and opportunity for objection before the grant of waiver can become effective.
49 CFR 192.1013 gives the operator an option to reduce the frequency of periodic
inspections and tests required for atmospheric corrosion inspections on the basis of the
engineering analysis and the required risk assessment. The operator must submit its
proposal to PHMSA or to the appropriate state agency. The applicable oversight
agency may accept the proposal on its own authority, with or without conditions and
limitations, on a showing that the operator's proposal, which includes the adjusted
interval, will provide an equal or greater overall level of safety.
On February 6, 2019, the Board issued an order granting IPL’s atmospheric corrosion
waiver request. On April 29, 2019, the Board issued an order stating that the waiver
approval by the Board was required to be forwarded to PHMSA for review and approval
in accordance to 49 U.S.C . § 60118(d).

On May 6, 2019, IPL filed a response to April 29, 2019 order. In its response, IPL
stated that it has not requested and does not intend to request a waiver of the federal
pipeline safety rules. IPL states that it sought a deviation to inspection intervals under
49 CFR 192.1013. According to IPL, the federal rule allows the Board to accept a
pipeline operator’s proposal to reduce the frequency of periodic inspections on its own
authority.
On June 27, 2019, the Board issued an “Order Addressing Waiver and Directing Letter
to the Pipeline and Hazardous Materials Safety Administration” directing Board staff to
send a letter to PHMSA requesting a response regarding the authority of the Board to
grant a deviation pursuant to 49 CFR 192.1013. The Board wants to ensure the
approved waiver doesn’t violate its agreement with PHMSA, nor does the Board want to
require IPL to comply with conditions that may not be necessary for the deviation in the
frequency of periodic inspections.
This letter is being sent in compliance with the Board’s June 27, 2019 order. PHMSA is
requested to provide a response regarding the Board’s authority to grant a deviation
pursuant to 49 CFR 192.1013. A copy of the Board’s April 29 and June 27, 2019
orders, and the response filed by IPL on May 6, 2019, are attached to this letter for
reference.

ORDER ADDRESSING WAIVER AND DIRECTING LETTER TO THE PIPELINE
AND HAZARDOUS MATERIALS SAFETY ADMINISTRATION
(Issued June 27, 2019)
PROCEDURAL BACKGROUND
On February 6, 2019, the Utilities Board (Board) issued an order in Docket No.
SPU-2018-0007 and Docket No. RG-0150, and other unrelated dockets, which
included approval of a request filed on June17, 2017, by Interstate Power and Light
Company (IPL) to revise IPL’s atmospheric corrosion inspection frequency as
provided in 49 CFR 192.1013. On April 29, 2019, the Board issued an order stating
that the waiver approval by the Board was required to be forwarded to the Pipeline
and Hazardous Materials Safety Administration (PHMSA) for review and approval. In
the April 29, 2019 order, the Board identified certain conditions that the Board was
considering applying to the waiver when the waiver was sent to PHMSA for review.
On May 6, 2019, IPL filed a response to April 29, 2019 order. In its response,
IPL stated that it has not and does not intend to seek a waiver of the federal pipeline
safety rules. IPL states that it sought a deviation to inspection intervals under 49
CFR 192.1013. According to IPL, the federal rule allows for a state agency, such as

PAGE 2
the Board, to accept a pipeline operator’s proposal to reduce the frequency of
periodic inspections on the agency’s own authority.
IPL interprets the language in 49 CFR 192.1013(a) not to require review or
approval by PHMSA. The language in the federal rule states: “An operator may
propose to reduce the frequency of periodic inspections and tests required in this part
on the basis of engineering analysis and risk management assessment required by
this subpart.” Paragraph 49 CFR 192.1013(b) requires the operator to submit its
proposal, that involves intrastate facilities, to PHMSA or to a state agency, and the
state agency may accept the proposal with or without conditions.
IPL asserts that the language in 49 CFR 192.1013 allows the Board to grant
the deviation without PHMSA approval and IPL does not consider the conditions
described in the April 29, 2019 order to be appropriate. IPL states if further
discussion is needed, a meeting at which the Office of Consumer Advocate (OCA), a
division of the Iowa Department of Justice, participates would be welcomed, and IPL
suggests participation of other natural gas pipeline companies may also be helpful.
BOARD DISCUSSION
The Board has considered the provisions of 49 CFR 192.1013 and its
relationship to the provisions in 29 USC § 60118(d) that states:
“If a certification under section 60105 of this title or an agreement
under section 60106 of this title is in effect, the State authority may
waive compliance with a safety standard to which the certification or
agreement applies in the same way and to the same extent the
Secretary may waive compliance under subsection (c) of this section.

However, the authority must give the Secretary written notice of the
waiver at least 60 days before its effective date. If the Secretary
makes a written objection before the effective date of the waiver, the
waiver is stayed. After notifying the authority of the objection, the
Secretary shall provide a prompt opportunity for a hearing. The
Secretary shall make the final decision on granting the waiver.”
This section of the federal statute requires the Board to send any
waiver request approved by the Board to PHMSA. The regulation cited by
IPL, 49 CFR 192.1013, appears to allow the Board to approve a deviation
from periodic inspection requirements without requesting PHMSA approval.
The Board does not want to be in violation of the agreement with PHMSA to
act as an agent for inspections of natural gas pipelines, nor does the Board
want to require IPL to comply with conditions that may not be necessary for
the deviation in the frequency of periodic inspections.
To address this conflict, the Board will direct its Safety & Engineering
manager to prepare and send a letter to PHMSA outlining the issue. The
letter will be filed in this docket, as will any response received from PHMSA.
Once the Board has a response from PHMSA, the Board will determine if it
needs to make a formal request from PHMSA to approve the waiver, or if the
issue has been resolved pursuant to 49 CFR 192.1013.
The Board does not consider a meeting with OCA and other pipeline
companies necessary at this time since the issue is for PHMSA to address.

ORDER DIRECTING RESPONSE
(Issued April 29, 2019)
On February 6, 2019, the Utilities Board (Board) issued an order which
included approval of a request filed on June17, 2017, by Interstate Power and Light
Company (IPL) to revise IPL’s atmospheric corrosion inspection frequency as
provided for in 49 CFR 192.1013. To complete the approval process, the Board is
required to provide to the Pipeline and Hazardous Materials Safety Administration
(PHMSA) written notice of the waiver and allow PHMSA 60 days to review and
approve or object to the waiver.
In a similar waiver request approved by the Illinois Commerce Commission
(ICC), PHMSA approved a waiver request with certain conditions. The conditions
were as follows:
1. Outside of business districts, an atmospheric corrosion inspection must be
conducted at least once every four calendar years at intervals not
exceeding 51 months.
2. Inside of business districts, an atmospheric corrosion inspection must be
conducted at least once every calendar year at intervals not exceeding 15
months.

3. Identify, inspect, and notify the Board of additional areas where there are
greater corrosion rates requiring monitoring more frequently than once
every three calendar years. These areas include “hot spots” where there
are greater atmospheric corrosion rates, including:
a. above-ground pipelines where there is greater exposure to road
salts and chemicals;
b. areas where pipelines could have accelerated atmospheric
corrosion due to industrial chemicals in the atmosphere;
c. pipelines that may experience sweating due to pressure drop,
such as regulator stations, metering correctors, and large
customers’ regulator/meter sets;
d. inside regulator/meter sets that are subject to corrosive
environments;
e. other areas that show accelerated atmospheric corrosion; and
f. above-ground facilities under insulation.
4. Continue to train and qualify meter readers to report atmospheric
corrosion as well as any abnormal operating conditions discovered when
reading gas meters.
Since PHMSA has approved a similar waiver based upon the conditions listed
above, the Board considers it necessary to add these conditions to the waiver
request the Board approved in Docket No. RG-0150. Before adding the conditions
as part of the waiver request and sending the waiver with the conditions to PHMSA,
the Board will provide IPL an opportunity to file a response to the conditions and
address whether the conditions are consistent with IPL’s waiver request.

RESPONSE TO ORDER
COMES NOW, Interstate Power and Light Company (IPL) and submits this
Response to the Iowa Utilities Board (Board) Order Directing Response issued on April
29, 2019.
Procedural History
On June 6, 2017, IPL filed a request with the Board to revise the frequency of
atmospheric corrosion inspections.
On March 28, 2018, the Board consolidated IPL’s request in the above-
referenced docket with tariff proceedings for IPL’s proposed non-standard meter
alternatives (NSMA), initially filed in Docket Nos. TF-2018-0029 and TF-2018-0030.
The NSMA tariffs and IPL’s atmospheric corrosion inspection request were
subsequently consolidated with NSMA-related complaint files (C-2018-0006, C-2018-
0007, C-2018-0008) into Docket No. SPU-2018-0007, via Board order issued July 30,
2018.
On February 6, 2019, the Board issued its Final Order and Decision in Docket
No. SPU-2018-0007 (February 6 Order), which included approval of IPL’s June 17,
2017 request to revise atmospheric corrosion inspection frequency, as provided for in
49 CFR § 192.1013. Ordering Paragraph 8 stated:

<<<PAGE 13>>>

Filed with the Iowa Utilities Board on July 19, 2019, RG-0150
Filed with the Iowa Utilities Board on May 6, 2019, RG-0150
8. Interstate Power and Light Company’s request to modify its inspection
frequency for atmospheric corrosion for intrastate pipelines, as filed in Docket
No. RG-0150 on June 16, 2017, is approved.
The Board issued a subsequent order on April 29, 2019, in Docket No. RG-0150, (April
29 Order) seeking additional information from IPL, and indicating the Board’s belief that
it is required to provide the Pipeline and Hazardous Materials Safety Administration
(PHMSA) with notice of the waiver and allow PHMSA 60 days to review and approve or
object to the waiver.
Response
IPL has not sought, and does not intend to seek a waiver of federal pipeline
safety rules; rather IPL sought a deviation to inspection intervals under 49 CFR Subpart
P, Gas Distribution Pipeline Integrity Management, specifically §192.1013. This federal
rule allows for an applicable oversight agency (in this case, the Board) to accept a
pipeline operator’s (in this case, IPL’s) proposal to reduce the frequency of periodic
inspections on its own authority.
§192.1013 When may an operator deviate from required periodic
inspections under this part?
(a) An operator may propose to reduce the frequency of periodic inspections
and tests required in this part on the basis of the engineering analysis and
risk assessment required by this subpart.
(b) An operator must submit its proposal to the PHMSA Associate
Administrator for Pipeline Safety or, in the case of an intrastate pipeline
facility regulated by the State, the appropriate State agency. The
applicable oversight agency may accept the proposal on its own authority,
with or without conditions and limitations, on a showing that the operator's
proposal, which includes the adjusted interval, will provide an equal or
greater overall level of safety.
(c) An operator may implement an approved reduction in the frequency of a
periodic inspection or test only where the operator has developed and
implemented an integrity management program that provides an equal or
2

Filed with the Iowa Utilities Board on May 6, 2019, RG-0150
improved overall level of safety despite the reduced frequency of periodic
inspections.
(Emphasis added).
The above-referenced federal rule language, codified on December 4, 2009,
allows a pipeline operator to propose a deviation from required periodic inspections.
IPL does not interpret 49 CFR §192.1013(a) to require review or approval by PHMSA.
The Board’s April 29 Order references a waiver which the Illinois Commerce
Commission (ICC) obtained from PHMSA to approve a waiver request from Ameren
Companies related to atmospheric corrosion surveys. However, that request was
granted in 2006, prior to the adoption of the rule language noted above, which provides
the option of requesting a deviation from required periodic inspections from the
applicable state oversight agency.
In light of the 2009 rule change, IPL does not believe a waiver from PHMSA is
required. If additional information is needed or further discussion of the federal rule is
warranted, IPL respectfully requests that the Board permit a meeting between Board
Staff and IPL. IPL also welcomes participation by the Office of Consumer Advocate
(OCA), and suggests that it may also be useful to notice the meeting to other natural
gas utilities in Iowa.

its April 29 Order and let the February 6 Order stand; or, in the alternative, permit a
meeting between IPL and Board Staff to discuss the federal rule language.
