REQUEST FOR INFORMAL CONFERENCE, REQUEST FOR HEARING AND
PRELIMINARY STATEMENT OF ISSUES FOR NOPV ITEMS 5 AND 6
WRITTEN RESPONSE TO NOPV ITEMS 1, 2, 3, 4, 7, 8, 9, AND 10
I. Request for Informal Conference Regarding NOPV Items 5 and 6
Pursuant to 49 U.S.C. § 60117(b)(1)(B), Tallgrass Pony Express Pipeline, LLC (Tallgrass)
respectfully requests an informal meeting to discuss the allegations in Items 5 and 6 of the above-
referenced Notice of Probable Violation, Proposed Civil Penalty, and Proposed Compliance Order
(NOPV). Tallgrass is hopeful that through further discussion of the facts and circumstances around
Items 5 and 6 that these portions of the NOPV can be addressed without a hearing.
II. Request for Hearing Regarding NOPV Items 5 and 6
Pursuant to 49 C.F.R. §§ 190.208(a)(4) and 190.211(b), Tallgrass respectfully requests an
in-person hearing to discuss the alleged violation and proposed civil penalties for Items 5 and 6. If
a hearing is held, Tallgrass will be represented by counsel at the hearing.
III. Preliminary Statement of Issues
Tallgrass respectfully contests the allegations of violation and proposed civil penalties for
Items 5 and 6, concerning the Company’s Integrity Management Program. At the hearing,
Tallgrass intends to raise the following issues:



Tallgrass Pony Express Pipeline, LLC
CPF 3-2021-046-NOPV
Item 5 – 49 C.F.R. §§ 195.452(b)(4)(i) and 195.452(f)(6) – Identification of Preventive
and Mitigative Measures
A. Whether, based on the allegation in the Notice and evidence in the record, PHMSA met
its burden of proof and persuasion that Tallgrass committed a probable violation of 49
C.F.R. §§ 195.452(b)(4)(i) and 195.452(f)(6).
B. Whether Tallgrass can present evidence that it had a process for identifying preventive
and mitigative measures to protect its facilities, as well as documentation that that
process was implemented.
C. Whether the proposed penalty must be withdrawn.
Item 6 – 49 C.F.R. § 195.452(l)(1)(ii) – Documentation of Information Analysis
A. Whether, based on the allegation in the Notice and evidence in the record, PHMSA met
its burden of proof and persuasion that Tallgrass committed a probable violation of 49
C.F.R. §§ 195.452(l)(1)(ii).
B. Whether Tallgrass can present evidence that it documented its information analyses
under §§ 195.452(g) and 195.452(l)(1)(ii), including the integration of Pipe Evaluation
Reports in the information analysis, and also into other aspects of its Integrity
Management Program.
C. Whether the proposed penalty must be withdrawn.
Tallgrass reserves the right to supplement this preliminary statement of issues in response
to any additional information or arguments from PHMSA.
IV. Written Response to NOPV Items 1, 2, 3, 4, 7, 8, 9, and 10
Pursuant to 49 C.F.R. §§ 190.208(a)(2), 190.208(a)(3) and 190.208(b)(3) Tallgrass
provides the following written response to Items 1, 2, 3, 4, 7, 8, 9, and 10 of the NOPV.
A. Item 1 – 49 C.F.R. § 195.310(a)
Tallgrass respectfully contests this alleged probable violation. Tallgrass has complete
documentation of the pressure test for Tank 3400 at the Natoma Kansas station. PHMSA alleged
that Tallgrass did not provide records in accordance with 49 C.F.R. § 195.307 and API Std 650,
Sections 7.3.5. and 7.3.6. Specifically, PHMSA asserts that Tank 3400 “did not have a record of
2



Tallgrass Pony Express Pipeline, LLC
CPF 3-2021-046-NOPV
fill level or test duration to confirm the pressure of the hydrotest after construction.” However,
Tallgrass does in fact have records of these parameters.
Tallgrass is contesting this violation. API 650 Section 7.3.5 Testing of the Shell 7.3.6
Hydrostatic Testing Requirements requires the following criteria for a hydrostatic test of a tank:
7.3.5 Testing of the Shell
After the entire tank and roof structure is completed, the shell (except for the shell of tanks
designed in accordance with Annex F) shall be strength-tested and the foundation initially
loaded by one of the following methods, as specified on the Data Sheet, Line 14:
1. If water is available for testing the shell, the tank shall be filled with water as
follows: (1) to the maximum design liquid level, H; …….the tank shall be
inspected frequently during the filling operation……..
7.3.6 Hydrostatic Testing Requirements
7.3.6.5
1. Shell elevation measurements shall be made at equally-spaced intervals around
the tank circumference not exceeding 10 m (32 ft). The minimum number of shell
measurement points shall be eight.
2. Observed elevations shall be referred to a permanent benchmark. The level
instrument shall be set up at least 1 1/2 times tank diameter away from the tank
when tank elevation readings are taken. Six sets of settlement readings are
required:
a. Before start of the hydrostatic test;
b. With tank filled to 1/4 test height (±600 mm [2 ft]);
c. With tank filled to 1/2 test height (±600 mm [2 ft]);
d. With tank filled to 3/4 test height (±600 mm [2 ft]);
e. At least 24 hours after the tank has been filled to the maximum test height.
This 24-hour period may be increased to duration specified on the data sheet if
the Purchaser so requires for conditions such as:
i. The tank is the first one in the area,
ii. The tank has a larger capacity than any other existing tank in the area,
iii. The tank has a higher unit bearing load than any other existing tank in
the area,
iv. There is a question regarding the rate or magnitude of settlement that
will take place;
f. After tank has been emptied of test water.

Tallgrass Pony Express Pipeline, LLC
CPF 3-2021-046-NOPV
With respect to the specific inadequacies alleged in the NOPV, Tallgrass provides the following
information:
Fill Height and Elevation Measurements: During the inspection, Tallgrass provided
the document titled Hydrotest Survey Natoma KS 2017-12-21 which indicated that the
required elevation measurements were taken at all six (6) fill heights described in API
650 Section 7.3.6.5(b) above, and at a distance around the tank not exceeding 10 m (32
ft.) as required by API 650 Section 7.3.7.5(a). Tallgrass has included Natoma KS 2017-
12-21 in Attachment 1 to this response.
Test Duration: During the inspection, Tallgrass provided the tank inspector’s reports
from December 1, 2017 through to December 5, 2017, which list the start of the test, the
dates and times that the 1/4, 1/2, 3/4 and full levels were reached, when the 24-hour hold
began and concluded, when the tank was emptied, and an indication that no leaks were
discovered as required by API 650 Section 7.3.6. Tallgrass has included the tank
inspector’s reports in Attachment 1 to this response.
Test Pressures: PHMSA alleges that Tallgrass failed to confirm the pressure of the
hydrotest. However, Natoma Tank 3400 is an atmospheric pressure tank and was
therefore hydrostatically tested with a water fill at atmospheric pressure as required by
API 650. No pressure measurements are required for an atmospheric tank test. Tallgrass
has included a photograph of the tank nameplate in Attachment 1 to this response. This
photograph shows that Tank 3400 is an atmospheric pressure tank.
Based on the foregoing, and the records included in Attachment 1, Tallgrass respectfully
requests that PHMSA withdraw this Item. While this is a warning item, failure to withdraw it
would result in a factual error in the public record. This factual error, if allowed to persist, could
have harmful effects on Tallgrass in its future dealings with the public, third parties and
regulatory agencies.
Tallgrass also notes that since the inspection, in the spirit of continual improvement,
Tallgrass has created a new form to capture and centralize key information from tank pressure
test documentation.
B. Items 2 and 10 – 49 C.F.R. §§ 195.402(a) and 195.577(a)
Items 2 and 10 are warning items that relate to external corrosion control. With respect
to Item 2, Tallgrass offers the clarification that it discovered in a 2019 cathodic protection (CP)
system survey that certain decouplers on the NECL were malfunctioning. Tallgrass corrected the
issue and CP system potentials were elevated and met criteria within 15-months. With respect to
Item 10, Tallgrass wishes to clarify that there is no stray current interference on the NECL
pipeline. Instead, the NECL pipeline had a larger CP current requirement to achieve protection.

C. Item 3 – 49 C.F.R. § 195.406(b)
Tallgrass respectfully requests that PHMSA eliminate two instances of the alleged
overpressure violation and reduce the civil penalty for a variety of reasons. Each of the instances
of violation is set out below, along with additional information and explanation. Following the
discussion of each instance, Tallgrass provides explanation in support of a penalty reduction for
this Item.
1. 130% MOP on 08-04-18 for NECL North line at the Noble meter skid due to
power loss and ESD at Buckingham (ERL 1356, 1357, 1358).
Tallgrass respectfully requests that PHMSA remove this instance from the alleged
violation. The Emergency Response Line (ERL) notification for this event indicated that this
was a pressure exceedance of 130% MOP. ERLs are issued quickly in response to an undesired
event, and before any detailed investigation occurs. Upon further investigation Tallgrass
determined that an alarm had been set to trip based on an ANSI 150 class system, instead of the
actual, higher 450 psig MOP at the Noble meter skid. The Noble meter skid is all ANSI 300
rated and Tallgrass has set MOP to 450 psig based on station hydraulics. The pressure at the
Noble meter reached approximately 370 psig, below the 450 psig MOP at this location. As a
result, what appeared initially to be an MOP exceedance was not, in fact, an exceedance.
Tallgrass has reset the alarm to reflect the correct 450 psig MOP for the Noble meter skid.
Please see Attachment 2 for documentation of the 450 psig MOP at the Noble meter skid,
and a graph of the pressures during the event that shows the 450 psig MOP was never exceeded.
On the basis of these materials, Tallgrass requests that PHMSA remove this instance of violation
from Item 3 and reduce the number of instances of violation for this Item for purpose of
calculating the civil penalty under the gravity factor.
2. 115% MOP on 07-26-19 during startup on PXP North (ERL 1679).
Tallgrass does not contest this instance of the alleged violation. However, Tallgrass
requests that PHMSA provide a reduction in the civil penalty related to this allegation to reflect
that Tallgrass identified the causes of the problem and corrected them before the start of
PHMSA’s inspection in August 2020. Specifically, Tallgrass installed relief at Guernsey station
to prevent future overpressure events.
Please see Attachment 2 for the point-to-point verification that was conducted on the new
safety relief valve (SRV) installed in April of 2020. This documentation demonstrates that
Tallgrass corrected the problem before PHMSA’s inspection. On the basis of these materials,
Tallgrass requests that PHMSA provide a credit under the gravity assessment criteria, as more
fully described below, in the penalty section.

CPF 3-2021-046-NOPV
3. 114% MOP on 10-10-19 at Pawnee due to shut down of Hereford Ranch
Lateral, no surge relief (ERL 1773).
Tallgrass does not contest this instance of the alleged violation. However, Tallgrass
requests that PHMSA provide a reduction in the civil penalty related to this allegation to reflect
that Tallgrass identified the causes of the problem and corrected them before the start of
PHMSA’s inspection in August 2020. Specifically, Tallgrass installed a control valve and relief
system at the Pawnee station to prevent future overpressure events.
Please see Attachment 2 for the point-to-point verification that was conducted on the new
relief valve in May of 2020. This documentation demonstrates that Tallgrass corrected the
problem before PHMSA’s inspection. On the basis of these materials, Tallgrass requests that
PHMSA provide a credit under the gravity factor, as more fully described below, in the penalty
section.
4. 113% MOP on 3-18-20 at McPherson Lateral due to control valve failure
(ERL 2018).
Tallgrass respectfully requests that PHMSA remove this instance from the alleged
violation. The ERL notification for this event indicated that this was a pressure exceedance of
113% MOP. ERLs are issued quickly in response to undesired events, and before any detailed
investigation occurs. Upon further investigation Tallgrass determined that the MOP exceedance
only reached 102%, which is below the 110% MOP limit under § 195.406(b). The actual
pressure reached 291 psig, and the MOP at this location is 285 psig. Tallgrass has relief in place
at this location to prevent the pressure from exceeding the § 195.406(b) limit.
Please see Attachment 2 for a SCADA record that shows that the highest pressure
reached during the March 18, 2020, event was 291 psig, in reference to the High and High-High
alarms denoted by the red dashed horizontal lines. The High-High is set at 99% MOP, which
equates to 282 psig.
On the basis of these materials, Tallgrass requests that PHMSA remove this instance of
violation from Item 3 and reduce the number of instances of violation for this Item for purpose of
calculating the civil penalty under the Gravity factor.
5. 114.5% MOP on 6-25-20 at Hereford Lateral/Pawnee due to unintended
closure of control valve (ERL 2180)
Tallgrass does not contest this instance of the alleged violation. Tallgrass requests
adjustment of the civil penalty related to this instance under the gravity factor, as discussed
below.
Penalty Reduction for Item 3
Tallgrass respectfully requests that PHMSA reduce the proposed penalty for Item 3 on
the basis of the factual information described above and supported in the attached
6



Tallgrass Pony Express Pipeline, LLC
CPF 3-2021-046-NOPV
documentation. Tallgrass seeks a penalty reduction under the gravity, culpability, and as justice
may require factors at 49 C.F.R. §§ 190.225(a)(1), 190.225(a)(2) and 190.225(b)(2),
respectively.
First, as explained above, Tallgrass undertook further investigation of the 5 events
described above. As a result of that investigation, the Company determined that 2 of the 5 events
did not in fact result in an exceedance of 110% MOP, and therefore do not constitute violations
of § 195.406(b). On that basis, Tallgrass requests that PHMSA reduce the number of instances
of violation from 5 to 3 in the gravity section of the Proposed Civil Penalty Worksheet. Based
on that reduction, PHMSA should reduce the “additional gravity points for multiple instances of
violation” from 13.6 to 6.8. It is evident from other entries in PHMSA’s Proposed Civil Penalty
Worksheet that the agency ascribes 6.8 gravity points to a violation involving 3 instances of
violation.1 At a point value of $1,728, this instance-based gravity reduction should be $11,750.
Second, and also with respect to the gravity factor, PHMSA’s Proposed Civil Penalty
Worksheet adds 17 gravity points based on an assertion in the Violation Report that the
“violation occurred within an HCA or ‘could affect’ HCA.”2 This assertion appears to be based
on a statement from PHMSA’s Violation Report that “all Tallgrass pipelines in the system
contain HCA segments.
”3 Tallgrass has evaluated its HCA listings and determined that the
facilities where these events took place were not located in, nor could they affect an HCA.
Documentation demonstrating the non-HCA status of these facilities is contained in Attachment
3. None of the stations is listed in the attached HCA listings because none are in or could affect
an HCA. In addition, regarding PHMSA’s concern that the events at these locations could have
resulted in overpressures on connected pipeline segments that are in HCAs, all of the events only
affected station piping and none resulted in overpressure of mainline piping. As demonstrated in
the table below, the MOPs of the mainlines serving these stations is far above the MOP of the
station piping.
Station Station Piping
MOP (psig)
Mainline
MOP (psig)
Noble Meter (NECL) 450 1440
Guernsey South Terminal
(PXP North)
285 1440
Pawnee (Hereford Lateral) 285 1440
McPherson 285 1440
On this basis, Tallgrass requests that PHMSA reduce the gravity points from 17 to 7,
which should result in an additional reduction of $17,280. This adjustment is reasonable and
appropriate because none of the locations identified are an HCA facility. This adjustment also
reflects that no mainline HCA piping experienced an MOP exceedance as a result of the station
piping exceedances at these facilities.

additional gravity points of 6.8.

Third, with respect to the culpability factor, PHMSA provides up to a -15 point credit in
circumstances where an operator finds and fixes issues before a PHMSA inspection.
4
Specifically, such a credit is appropriate if “[a]fter the operator found the non-compliance, the
operator took documented action to address the cause of the non-compliance, and corrected the
non-compliance before PHMSA learned of the violation.”5 As explained above, Tallgrass
undertook and completed corrective action with respect to two6 of the three remaining instances
of violation before the inspection, and therefore the penalty should be reduced accordingly.
Given these efforts, PHMSA should provide a -10 point reduction under the culpability factor.
At a $1,728 point value, this results in an additional reduction of $17,280.
Finally, PHMSA has assigned 40 additional points under the “as justice may require”
factor, due to a repeat offense from a 2016 Final Order. Tallgrass does not contest that this is a
repeat offense. However, this 40-point assignment is based on an underlying 17-point gravity
score. As discussed above, because none of the overpressure events occurred in an HCA or a
could affect area, that gravity score must drop from 17 to 7 points. Based on the point ranges for
repeat offenses in PHMSA’s Proposed Civil Penalty Worksheet, the “as justice may require”
score should also drop, from 40 to 30 points. This adjustment results in an additional $17,280
reduction in the civil penalty.
Based on the various appropriate penalty adjustments described above, the civil penalty
for this item should be adjusted from $151,300 to $87,710.
Proposed Compliance Order for Item 3
Tallgrass requests that PHMSA clarify the Proposed Compliance Order to reflect that
Tallgrass may prevent MOP exceedance using a range of “adequate controls and
protective equipment,” pursuant to § 195.406(b), and not only surge relief devices as presently
specified in the Proposed Compliance Order.
D. Item 4 - 49 C.F.R. § 195.440(g)
Tallgrass respectfully requests that PHMSA convert this alleged violation into a Notice of
Amendment (NOA). Tallgrass acknowledges that it needs to improve its program for
communicating with non-English speakers. The Company intends to update its procedures
concerning determination of what is a “significant” non-English speaking population. And
reflecting PHMSA’s concerns, Tallgrass will rely on Spanish language mailers, instead of just the
Spanish language content on its website. PHMSA has the discretion to change this item to an
NOA and given the procedure-focused nature of PHMSA’s concern, doing so would be
reasonable.

E. Items 7, 8, and 9 – 49 C.F.R. §§ 195.573(a)(1) and 195.573(c)
The above-listed Items all relate to Tallgrass’ 2020 self-report of external corrosion
control survey and data issues. Tallgrass does not contest these Items. However, Tallgrass
respectfully requests that the Final Order in this case reflect the Company’s proactive efforts
to resolve the underlying issues and improve its practices and procedures. Those efforts are
summarized below.
As listed in detail in the Company’s self-report communications, after discovering these
issues, Tallgrass took steps to verify that they did not present safety concerns. Specifically,
Tallgrass conducted un-planned close interval surveys (CIS) and reads of cathodic
protection (CP) test stations, as well as an analysis of In-Line Inspection and other inspection and
repair data on affected pipeline segments. The results of these efforts confirmed that there were
no immediate corrosion-related safety concerns. Tallgrass then began several remedial actions to
prevent recurrence of the corrosion survey and data issues, including additional training,
improved corrosion data collection and tracking tools, review and amendment of relevant
corrosion procedures, establishment of an annual corrosion program performance review
meeting, quarterly data reviews, addition of personnel, and additional CIS and CP
system improvements.
Tallgrass shares PHMSAs commitment to pipeline safety and appreciates being
afforded the opportunity to work with PHMSA to ensure the safe operation of our pipelines.
Please do not hesitate to contact me if you have any questions about this response. I will contact
you to discuss scheduling an informal conference regarding Items 5 and 6.
Respectfully submitted this 21st day of
January 2022.

From August 2, 2020, to October 23, 2020, a representative of the Pipeline and Hazardous
Materials Safety Administration (PHMSA), Office of Pipeline Safety (OPS), pursuant to Chapter
601 of 49 United States Code (U.S.C.), inspected Tallgrass Pony Express Pipeline, LLC’s

As a result of the inspection, the Director, Central Region, OPS (Director), issued to Respondent,

the alleged violations, and proposed a civil penalty in the amount of $437,300 associated with

request and accept the findings of violation alleged in the Notice, subject to the clarifications as



set forth below, pay a reduced civil penalty in the amount of $385,500 for Items 3, 5, 6, 7, 8, and
9, and to undertake certain corrective measures.
Having agreed that settlement of this enforcement action will avoid further administrative
proceedings or litigation and will serve the public interest by promoting safety and protection of
the environment, pursuant to 49 C.F.R. part 190, and upon consent and agreement of Respondent
and PHMSA, the Parties hereby agree as follows:
I. General Provisions:

and the regulations and orders issued thereunder.

comply with all applicable requirements of the Federal pipeline safety laws, 49 U.S.C. § 60101,
et seq., and the regulations and orders issued thereunder. Nothing in this Agreement alters
PHMSA’s right of access, entry, inspection, and information gathering or PHMSA’s authority to



bring enforcement actions against Respondent pursuant to the Federal pipeline safety laws, the
regulations and orders issued thereunder, or any other provision of Federal or State law.
7. For all transfers of ownership or operating responsibility of Respondent’s pipeline
system referenced herein, Respondent will provide a copy of this Agreement to the prospective
transferee at least 30 days prior to such transfer. Respondent will provide written notice of the
transfer to the PHMSA Central Regional Director no later than 60 days after the transfer occurs.

regulations that are applicable to Respondent’s pipeline systems. This Agreement is not a
permit, or a modification of any permit, under any Federal, State, or local laws or regulations.
