`Request to Commence Installation of Underground Piping
`November 2 Supplement
`
`
`INTRODUCTION
`
`On November 22, 2019, the Federal Energy Regulatory Commission (“FERC” or “Commission”) issued an
`Order Issuing Authority Under Section 3 and Section 7(c) of the Natural Gas Act (“NGA”) (“Order”) granting
`the necessary authorization to Corpus Christi Liquefaction, LLC (“CCL”) and Cheniere Corpus Christi
`Pipeline, L.P. (“CCPL”) for the construction and operation of the Corpus Christi Liquefaction Stage 3 Project
`(“Stage 3 Project”).
`
`On October 20, 2022, CCL filed Implementation Plan-D to demonstrate compliance with Conditions 36, 44,
`47, 74, and 98 of the Order. CCL is herein submitting supplemental information in response to an information
`request from FERC dated October 26, 2022.
`
`CCL respectfully requests FERC’s authorization for Implementation Plan-D no later than November 14, 2022.

`FERC Docket No. CP18-512-000
`Request to Commence Installation of Underground Piping
`November 2 Supplement
`
`
`FERC comment received via email on October 26, 2022:
`
`FERC staff’s review of the October 20th filing for underground piping identified missing or deficient
`information. To facilitate our review of the underground piping, including line sizing, provide responses to the
`following and file response to the eLibrary docket:
`
`1. Provide detailed plot plans (or areas) of the ISBL and OSBL areas. Plot plans should label or tag all
`equipment and vessels in these areas.
`2. Provide piping specifications for all underground lines in the scope of this authorization request.
`3. Attachment 74, Section 3.5.1 makes references to Fire Water Demand Calculation Doc. No. 26290-
`100-U1C-3033-00001. This document was not included in the filing. Provide this document for FERC
`staff review.
`4. Condition 96 of the November 22, 2019 Order specifies active protection, passive protection, or a
`combination of the two for each significant component within the 4,000 Btu/ft2-hr radiant heat zone
`from pool or jet fires. Firewater would be component of active protection. Provide the quantitative
`analysis if available. Otherwise, explain how the design of the underground firewater system piping
`has the capacity to support adequate mitigation.
`
`
`
`CCL Response:
`
`1. Detailed plot plans for ISBL and OSBL areas are provided in Attachment 1A.
`2. Piping specifications for all underground lines within the scope of this approval are provided in
`Attachment 2A.
`3. Fire Water Demand Calculation, Document. No. 26290-100-U1C-3033-00001 is provided in
`Attachment 3A.
`4. Attachment 01 (Firewater Coverage Schedule) on page 13 of the Fire Water Demand Calculation
`provided in Attachment 3A above, provides a synopsis of the necessary fire water for the
`applicable equipment in order to satisfy NFPA 15 (2017) Cl 7.3.2 and Cl. 7.4.2. All necessary fire
`water coverage for the equipment that falls within the 4000 btu/ft2-hr thermal contour will be
`covered by the total sizing capacity of the Project fire water system which has a maximum
`capacity of 4,000gpm, and/or passive fire protection. The maximum capacity for the fire water
`ring main basis can be found in Table 7.3-1 ISBL Fire Zone -wise Fire Water Demand on page 8
`of the above referenced fire water demand calculation, which depicts the basis of one fire zone
`that requires five (5) fire water monitors and a hose allowance. This results in a capacity of
`3,500gpm. A margin is added on top of that total application need. As the 4,000gpm maximum
`capacity is higher than any fire water coverage need, the fire water underground pipe to be
`installed under this requested approval will be able to handle any scenario where active protection
`is needed.
