This is a change from 87 psig (minimum) as defined in the Battery Limit Schedule, 195910-000-PR-SH-1001. As a result of the reduction in potable water supply pressure, required design changes include:

    Adjustment of line sizes and valving as required to deliver water from the battery limit to each of T- 6305, T-6401, and T-7605 with consideration of the revised supply pressure.

    Supplying all potable water users directly from the plant drinking water pumps, P-6401A/B, to ensure sufficient pressure at each user. The sizes of P-6401A/B are increased accordingly.

    Addition of piping as required to connect P-6401A/B to all users; and

2)    Per RFI-RG-BL-GRI-GAM-00117, Rev. 2 (item #2 of the original query description) concerns were raised about the water quality in the potable water tank. To address the water quality in the potable water tank, required design changes include:

    Addition of a cross-over line from potable water pumps to the service water tank to ensure minimum turnover of water in the potable water tank.

For clarity, item# 3 of the original query description in RFI RG-BL-GRI-GAM-00117, Rev. 2 is not in the scope of this Change Order.

TITLE: REMOVAL OF TRUCK WEIGH BRIDGES & ADDITION OF BOG CONTROL VALVES

The EPC Agreement between the Parties listed above is changed as follows: (attach additional documentation if necessary)

BACKGROUND

Truck Weigh Bridge

TNQ092 was raised during FEED verification and identified a need to incorporate truck weigh bridges and scales into the condensate metering system at each loading location to achieve meter accuracy requirements and provide overfill protection and therefore two weigh bridges and scales were added to the scope. Further review determined that utilizing weigh bridges and scales is not typical and is not recommended as it will add unnecessary congestion and complexity to the area. The two weigh bridges are to be removed and manual sampling points and Coriolis meters will be installed.

Boil-Off Gas Control Valves

Flow control valves are to be added as shown in Attachment 3 to this Change Order within the battery isolation limits for Train 1 and Train 2 on the boil-off gas supply lines to the HP fuel gas system to allow for controlled distribution of boil-off gas between Train 1 and Train 2.
