components; ▪ PLC and OIT programming of panels supplied by others; ▪ Component inspections and startup for field process components/instruments and panels supplied

by others. 2. Since the new 02-LCP-01 panel is located in close proximity to ACP-5 at the Storm Station, we have

located the IO shown in 97Y005 in 02-LCP-01 to minimize field modifications and possible disruption to the Storm Station.

3. New panel 02-LCP-01 will be connected to the switch at ACP 5 via a new fiber optic patch cable. A fiber optic cable termination panel and fiber terminations will not be needed or provided at 02-LCP-01.

4. Existing workstation will be moved to a new enclosure. It is assumed that the existing PC hardware is in working order and has the latest OS and SCADA software installed. The existing filtration system will be relocated to the new enclosure.

5. We explicitly take exception to all hand stations shown in 97Y001 (02-HS21, 02-HS22, 02-HS23, 02-HS24) and 97Y005 (21-HS02, 21HS03).

6. The pressure instrument annular seals are proposed with 1-inch FNPT bodies for connection to a tap on the side of the process line. Each seal assembly will have an isolation ball valve and bleed-off ball valve with a 1-inch union between the inlet valve and seal. We understand this configuration to be preferred by the Owner in lieu of in-line full line size seals.

7. Pressure switches furnished as part of this proposal require three (3) wires for operation. Please coordinate provision of adequate wire as needed.

8. All instruments and panels furnished under the scope of this proposal will be provided with the manufacturers’ standard finish.
