Anadarko Data Request 1.2 16'Supplemental
Anadarko Data Request 1.2
Please identify the number of natural gas,oil,or water pipelines and utilities that are
located within the right-of-wayor will intersect the proposed transmission line right-of-
way.
(a)With respect to said pipelines or other utilities,please describe the additional
measures that Rocky Mountain Power will undertake to mitigate the effect of
electromagnetic corrosion or effects of alternate current.
16*SupplementalResponse to Anadarko Data Request 1.2
Without waiving its prior objection to this data request regarding the scope of certificate
of public convenience and necessity (CPCN)proceedings (see refer to the Company's
response to Anadarko Data Request 1.2),Rocky Mountain Power provides the following
supplemental information:
Please refer to Confidential Attachment Anadarko 1.2 16*Supplemental.The attachment
reflects available information regarding oil and natural gas and utility pipelines located
within a one mile buffer or along the transmission line rights-of-wayincluded in this
docket.
Rocky MountainPower's approach to mitigating the effect of electromagnetic corrosion
or effects of alternating current on pipelines or other utilities located in proximity to
Rocky Mountain Power's transmission infrastructure is evaluated on a case-by-case
basis.Rocky Mountain Power would generally describe its approach as proactive
coordination with pipeline businesses during the permitting,engineering,and
construction phases of high voltage transmission line projects to ensure final designs and
necessary corrosion mitigations do not impact the daily operation and long-term life
expectancy of the pipelines.The Company's experience includes coordination with
pipelines transporting natural gas and liquid petroleum fuels.The approach is similarly
applied to transmission line projects undergoing the National Environmental Policy Act
Environmental Impact Statement permitting process and those not required to undergo
such permitting.The Company's recent experience with the Mona to Oquirrh500/345
kilovolt (kV)transmission line and Sigurd to Red Butte 345kV transmission line required
coordination with three pipelines,for example.More specifically,alternating current
(AC)interference,includingcorrosion potential,is studied to determine any impacts the
transmission line may cause.Site and condition specific protective mitigations are then
designed and installed where indicated.Mitigations may include facility grounding,line
micro-siting adjustments,operatorprotection,corrosion protection and/or other
appropriate solutions.
Confidential information is provided subject to the terms and conditions of the protective
agreement in this proceeding.

Anadarko Data Request 1.3 13'Supplemental
Anadarko Data Request 1.3
The RAV 14 attachment to the Rick Vail Direct Testimony identifies mine operations
within a one mile buffer or along the transmission line,including uranium,coal,and sand
and gravel operations.Please describe the oil and natural gas,including coalbed methane
gas,leases,development,and production occurring within a one mile buffer or along the
transmission line right of-way.
16*SupplementalResponse to Anadarko Data Request 1.3
Without waiving its prior objection to this Data Request regarding the scope of certificate
of public convenience and necessity (CPCN)proceedings (refer to the Company's
response to Anadarko Data Request 1.2),Rocky Mountain Power provides the following
supplemental information:
Please refer to Attachment Anadarko 1.3 16'Supplemental.The attachment reflects
information regarding oil and natural gas leases (includingcoalbed methane gas,as well
as development and production wells),and mining operations located within a one mile
buffer or along the transmission line rights-of-wayincluded in this docket.

Anadarko Data Request 1.4 1st Supplemental
Anadarko Data Request 1.4
Please explain the basis for not addressing the impacts of the Transmission Line on the
Bitter Creek Coal Mines.
16*SupplementalResponse to Anadarko Data Request 1.4
Without waiving Rocky Mountain Power's prior objection to this Data Request regarding
the scope of certificate of public convenience and necessity (CPCN)proceedings (see the
Company's response to Anadarko Data Request 1.2),the Company hereby provides this
supplemental response.
The Company did not address the impacts of the Transmission Projects on the Bitter
Creek Mines in its CPCN application because (1)the impact of the Transmission Projects
on an individualproperty interest such as the Bitter Creek Coal Mines is outside the
scope of a CPCN filing;and (2)the Transmission Project,pursued with the reasonable
approaches that the Company has described in its testimony in this docket and
successfully implemented with landowners across its transmission system historically,
will not result in foreclosure of an entire mineral estate.

Anadarko Data Request 1.5 161 Supplemental
Anadarko Data Request 1.5
Page 40 of the Rick Vail Direct Testimony states:
No mineral rights or minerals are required for the construction,operation,and
maintenance of the Transmission Projects.If,during negotiations with landowners,
conflicts arise with the placement of the transmission line,mineral rights or extraction
terms will be negotiated with the landowner to mitigate the impact (i.e.,line relocation,
compensation,etc.).
(a)Please describe how the relocation process referred to in Rick Vail's testimony would
be implemented to avoid conflicts withexisting mineral operations,such as a coal
mine or trona mine,includinghow far Rocky Mountain Power could and would move
a transmission line.
(b)Please state if Rocky Mountain Power has initiated negotiations with landowners and
the status of those negotiations.
(c)Please identify and describe the information that Rocky Mountain Power has
regarding the number of plugged wells and abandoned mines within the right-of-way.
16 SupplementalResponse to Anadarko Data Request 1.5
Without waiving Rocky MountainPower's prior objection to this Data Request regarding
the scope of certificate of public convenience and necessity (CPCN)proceedings (see the
Company's response to Anadarko Data Request 1.2),the Company provides this
supplemental response to subparts (a)and (c);the Company previously responded to
subpart (b).
(a)The Company does not anticipate that the Combined Projects will have significant
conflicts with existing mineral operations.The majorityof the Aeolus-to-
Bridger/Anticlinetransmission line is sited in a corridor that tracks Interstate 80 and
includes existing 230 kV transmission lines,buried gas pipelines and fiber optic
cables,and a Union Pacific railroad line.If mineral rights are affected,micro-siting
adjustments are a possible mitigation strategy.The distance the transmission line
could and would be moved is not pre-determined,but rather is a site-specific inquiry,
subject to a wide range of different factors.
(c)The Company has determined that within the proposed right-of-wayof the project,
there is one plugged/abandonedoil and gas well in Sweetwater county (latitude:
41.62477,longitude:108.03251)and there are no abandoned mines.
