Subject: RE: [External] RE: Alamance Aggregates DEQ Permit and Colonial Pipeline
Attachments: CPC Supplemental Comments - AA Mining Permit Application FINAL NCDEQ
08.06.2020.pdf
Brian and Judy,
Attached to this message is a file that presents recommended Terms and Conditions that Colonial Pipeline Company has
prepared for NCDEQ consideration regarding the Alamance Aggregates LLC draft permit to operate a crushed stone
mining operation near Clark Road in Snow Camp, Alamance County, North Carolina. The attached file includes a cover
letter and an attachment with the specific terms and conditions.
In a discussion with Judy yesterday, she indicated that NCDEQ does not intend to include any conditions related to
blasting for scaled distance in the Terms and Conditions included as part of the draft permit. Colonial believes that a
specific reference scaled distance is a key component to ensuring the integrity of Colonial's pipelines in the vicinity of
the proposed mining operation. If not a specific condition of the draft permit, Colonial supports specifically requiring
that the Blasting Plans prepared under any permit issued to Alamance Aggregates would need to specify the scaled
distance for each blast.
Thank you for considering Colonial's recommendations. Please contact me with any questions.

Subject: [External] RE: Alamance Aggregates DEQ Permit and Colonial Pipeline
Dear Representative Riddell,
Thank you for reaching out to us to check in on the status of Colonial Pipeline's ongoing communications with
representatives of Alamance Aggregates. Colonial and Alamance Aggregates have been working on finalizing the terms
and conditions that need to be addressed as they relate to blasting activities at the proposed Alamance Aggregates
quarry operation in Snow Camp. Colonial is also continuing to maintain communication with the North Carolina
Department of Environmental Quality (NCDEQ) to ensure that similar terms and conditions are included in any mining
permit that the NCDEQ would issue for the proposed quarry operation.

I am providing an update to each of the topics that were included in our prior email exchanges.
1. Relocation of Emergency Access Roadway — Colonial requested and Alamance Aggregates has indicated that
they will agree to provide an alternative location for the currently situated emergency access roadway north of
the site that crosses the Colonial's pipelines and easement. Through its response to NCDEQ information requests
to support the mining permit application process, Alamance Aggregates has submitted a revised site plan to the
NCDEQ as part of its permit application that includes an alternate Emergency Access roadway that does not
cross Colonial's pipelines.
See attached file labelled "C201-Mine-Map." With this drawing now included in the permit application, approval
of the permit would require that Alamance Aggregates construct the alternate Emergency Access roadway at
the location shown on the attached drawing and no longer use the current field road that is marked on prior
site plans as the emergency access location.
2. Detailed Third -Party Analysis of Potential Impacts to Colonial's Pipelines due to Surface Loading by Drilling Rig
— As previously indicated in our discussion with you and the other representatives of the local community,
Colonial engaged an independent engineering consulting firm to conduct an initial assessment of the potential
impacts on Colonial's pipelines due to the surface loads from the heavy drilling equipment that crossed our
easement. The results of that initial analysis indicated that there are no concerns with the integrity of
Colonial's pipelines due to the limited occurrence of vehicles crossing Colonial's easement.
A more detailed analysis is being addressed by Colonial. I am coordinating with internal staff to obtain the
necessary data required to complete the additional assessment, and confirm the initial evaluation completed by
the independent engineering contractor.
3. Colonial Representative on -site During Blasting — Alamance Aggregates has indicated that they will agree to
provide advanced notice to Colonial of any blasting at least two days prior to blasting occurring, including a
Blasting Plan for review by Colonial's representatives. Based on Colonial's analysis on the location of where
the blasting will occur relative to Colonial's pipelines and the blast charge, an evaluation will be performed to
determine whether a Colonial representative will need to be on -site to observe and monitor the drilling of the
borings for the blast charge and the blasting activity. Colonial has an established procedure that determines the
level of oversight needed based on the specific details of the proposed blast, and will make its determination
based on this procedure.
4. Web -based Data Room — Alamance Aggregates has indicated that they will agree to provide access to a web -
based data room for all seismograph monitoring data recorded during blasting events. This website will be
password protected and access will only be provided to Colonial's designated representatives and Alamance
Aggregates and its affiliates. Alamance Aggregates also indicated that they will agree to input all blast data
within 24 hours of the event occurring. The web -based data room is being created to provide Colonial with
confirmation that the blasting activities (as monitored by the seismographs) have not affected Colonial's
system and that the work was conducted in accordance with the Blasting Plan.
NCDEQ can request data from Alamance Aggregates at any time, whether stored in the web -based data room or
otherwise, to assess compliance with any permit that may be issued. Colonial previously provided a copy of an
email sent to Colonial by Alamance Aggregates confirming the establishment of the web -based data room.
S. Permit Conditions Requested by Colonial — Colonial previously submitted a list of conditions that we believe
need to be included in any permit that may be issued by NCDEQ to Alamance Aggregates to operate the
mine. More recently, Alamance Aggregates submitted the terms and conditions that they believed would be
appropriate to have written into the permit. Colonial has reviewed those conditions and generally agrees with
what has been presented by Alamance Aggregates. However, Colonial is also planning to send a separate

communication to NCDEQ with our final list of terms and conditions to be included in the permit that provides
for protection to Colonial's pipeline assets and safe operation of our system. Colonial contacted NCDEQ earlier
today and confirmed our intent to submit a final set of terms and conditions to be included in any permit
issued.
In summary, we are nearing completion on addressing the terms and conditions with Alamance Aggregates and expect
to have all matters addressed soon.

Subject: [External Message] Alamance Aggregates DEQ Permit and Colonial Pipeline
WARNING: phis email originated outside or Colonial Pipeline.
DO NOT CLICK links or attachments unless you recognize the sender and know the content is safe.
Good Morning Mark and Chip,
I hope this finds everyone well and staying safe.
As the Alamance Aggregates permit process continues to unfold with DEQ I would like to get an update regarding the
action items we discussed during our meeting at my home earlier this year.
During that interim we have all had to adjust and rework our lives and livelihoods around the Covid 19 impact. I
understand Colonial Pipeline was not immune to the disruption caused by the virus. However, since a good amount of
time has passed since that meeting and the permit process is likely not to continue on indefinitely can you tell me if
subsequent meetings between Colonial and Alamance Aggregates have led to some agreements being reached
regarding the items below?
1. Relocation of Emergency Access Roadway - Colonial requested and Alamance Aggregates agreed to provide an
alternative location for the currently situated emergency access north of the site that crosses the Colonial's
pipelines and easement. The alternative location would be curved eastward to intersect with Quakenbush Road
south of the pipeline. Alamance Aggregates representatives will work with the local Duke Energy representative
to confirm that relocating this road within Duke ROW poses no problem, with Colonial providing support as
needed through its contacts at Duke Energy. Alamance Aggregates will also approach NCDOT about a driveway
permit for the new entrance and access to Quakenbush Road. A revision to the NCDEQ permit application has
been submitted by Alamance Aggregates, and Colonial spoke with NCDEQ today about the necessary steps to
have the alternate Emergency Access defined in the permit and one of the conditions that would need to be met
prior to issuing the permit. Colonial will keep your group informed on progress with regard to this item.
2. Detailed Analysis of Potential Impacts to Colonial's Pipelines due to Surface Loading by Drilling Rig— Colonial is
continuing to compile the data required to complete the detailed surface loading analysis related to the well
drilling rig crossing over the pipelines located beneath the Emergency Access field roadway. To ensure a

comprehensive analysis, Colonial is extracting specific data on pipeline operations on the days that the drilling
work was being performed at the site by Alamance Aggregates' representatives (October 22 & 26 and November
8 & 16, 2019). Colonial expects to have the information compiled by next week and the analysis completed
shortly after confirming we have the files required to support the evaluation.
3. Colonial Representative on -site During Blasting—Alamance Aggregates has agreed to provide advanced notice
to Colonial of any blasting at least two days prior to blasting occurring. Based on Colonial's analysis on the
location of where the blasting will occur relative to Colonial's pipelines and the blast charge, an evaluation will
be performed to determine whether a Colonial representative will need to be on -site to observe and monitor
the drilling of the borings for the blast charge and the blasting activity. Colonial has an established procedure
that determines the level of oversight needed based on the specific details of the proposed blast, and will make
its determination based on this procedure.
4. Web -based Data Room —Alamance Aggregates has agreed to provide access to a web -based data room for all
seismograph monitoring data recorded during blasting events. This website will be password protected and
access will only be provided to Colonial's designated representatives and Alamance Aggregates and its affiliates.
Alamance Aggregates has agreed to input all blast data within 24 hours of the event occurring. For a number of
reasons, the web -based data room will not be accessible by the public. Any public requests for data and
information will need to be made through NCDEQ. A copy of the email sent to Colonial confirming the
establishment of the web -based data room is attached to this message.
5. Permit Conditions Requested by Colonial — Colonial previously submitted a list of conditions that we believe
need to be included in any permit that may be issued by NCDEQ to Alamance Aggregates to operate the
mine. In addition, we have met directly with Alamance Aggregates and NCDEQ representatives to provide the
technical basis and justification for the suggested conditions to be included in a permit. Since the submittal of
the original permit application by Alamance Aggregates, supplemental information has been provided to NCDEQ
regarding the Emergency Access roadway. Colonial is reviewing the additional information and preparing final
recommendations for the permit conditions that NCDEQ should consider in issuing the final permit. While we
are confident that those conditions will be included, NCDEQ has the final authority on the permit terms and
conditions when issued. Colonial is continuing its discussions with Alamance Aggregates and NCDEQ to ensure
that permit conditions are included that provide for protection to Colonial's pipeline assets and safe operation
of our system.

RE: Supplemental Comments and Permit Terms & Conditions - Mining Permit Application
Alamance Aggregates, LLC
Snow Camp, NC
Dear Ms. Wehner:
Colonial Pipeline Company (Colonial) previously submitted comments regarding the Mining
Permit Application that has been submitted to the North Carolina Department of Environmental
Quality (NCDEQ) by Alamance Aggregates, LLC (Alamance Aggregates) to operate a crushed stone
mining operation near Clark Road in Snow Camp, Alamance County, North Carolina. This letter is a
supplement to the prior letters (dated December 17, 2018 and May 16, 2019) submitted by Colonial
to NCDEQ regarding this matter, and presents recommended specifications and requirements that
Colonial believes should be included as terms and conditions in any operating permit, if issued to
Alamance Aggregates, to operate the proposed mine and quarry operation in a manner that will help
ensure the protection of Colonial's nearby refined petroleum products transport pipelines. This
additional clarification and the specifications for terms and conditions are based on Colonial's further
discussion with representatives of Alamance Aggregates and NCDEQ.
As indicated in Colonial's prior letters to NCDEQ on the Mining Permit Application, Colonial
operates an underground refined petroleum products pipeline that is located in the immediate vicinity
of the proposed crushed stone mine site and is on the property owned by Alamance Aggregates. The
blasting activity that will be performed as part of the mining and quarrying operations could represent
a threat to the integrity of Colonial's pipeline if institutional and engineering controls are not included
in any operating permit issued. These controls are designed to ensure that a "blasting encroachment"
condition does not exist relative to the pipeline. Colonial believes it is necessary that the NCDEQ
approve the conditions recommended by Colonial in order to protect the integrity of the pipeline.
1185 Sanctuary Parkway, 2nd Floor Alpharetta, Georgia 30009

Based on Colonial's review of the available information in the NCDEQ administrative record,
including documents, maps, and diagrams prepared by Alamance Aggregates as part of the permit
application process, Colonial is recommending and respectfully requesting that the items listed in
Attachment 1 to this letter be included as terms and conditions in any operating permit issued by
NCDEQfor the crushed stone mine. Colonial is recommending and requesting that the NCDEQ include
the terms and conditions shown in Attachment 1 to provide the institutional and engineering controls
necessary to mitigate any potential adverse effects to Colonial's pipeline system. Colonial has
developed the terms and conditions that, to the best of our ability considering the circumstances
posed by the mine, protect the integrity of the pipeline.
Please contact me at [phone] with any questions regarding these comments.
Sincerely,
nc

Colonial determines that permanent seismographs must be installed, then Colonial will
determine the appropriate number of permanent seismographs and their locations.
K. Use of Permanent Seismographs. If permanent seismographs will be used to monitor the
vibration level at Colonial's closest pipeline, at least five (5) permanent seismographs shall be
installed, and their respective locations must be approved by Colonial. The permanent
seismographs shall be provided by an independent 3rd party company that specializes in
vibration monitoring, paid for by Alamance Aggregates; such third -party contractor must first
be approved by Colonial in writing prior to the seismograph being administered. The
seismographs must be installed by trained and experienced personnel as per the most recent
guidelines published by the ISEE. After the mine pit at the Quarry has been developed or one
(1) year following the first permitted blast at the Quarry (whichever comes first), Colonial will
review the vibration data that has been collected by the permanent seismographs, and
Colonial will determine if the number of permanent seismographs and/or their locations must
be changed. If Colonial determines that the number of permanent seismographs and/or their
locations must be changed, Colonial will determine the required number of permanent
seismographs and their locations; the Parties agree to modify this Agreement accordingly.
The addition of any seismographs, and the relocation of any seismographs, must be
performed by an independent 3rd party company that specializes in vibration monitoring, paid
for by Alamance Aggregates; such third -party contractor must first be approved by Colonial in

QUARRY OPERATION REQUIREMENTS AND TECHNICAL CONDITIONS
A. Quarry Access. Alamance Aggregates shall provide points of ingress and egress into and out
of the Quarry that do not cross the Colonial Right -of -Way.
B. Relocation of Emergency Access. At Colonial's request, and after Colonial has consulted with
the NCDEQ, the access route on the northern portion of the Quarry property, as identified on
the attached Quarry Site Plan, which was obtained from permit application documents
submitted to NCDEQ by Alamance Aggregates (included as Exhibits 1A. and 1B.) and
delineated as "Emergency Access" shall be located and constructed by Alamance Aggregates
by curving the access road eastward to intersect with Quakenbush Road south of, but not
crossing over, traversing, or intersecting the Pipelines or Colonial's Right -Of -Way. It is the
intent of the Parties that no road or other access route, temporary, permanent, or otherwise
shall be established or used to cross over, traverse, or intersect the Pipelines or Colonial's
existing Right -of -Ways. This condition is contingent upon approval of a driveway permit by
the North Carolina Department of Transportation ("NCDOT") at the new location previously
described above in this Section II.B., which driveway permit is not expected to be withheld.
