Shaheerah,

As we discussed, I have attached for reference in tomorrow’s call current versions of the startup and isolation

procedures and daily plant readings forms found in the O&M Plan in Appendix A. As stated in our comments to the draft

permit, Resolute believes that replacing the existing O&M plan with a plan that better reflects current conditions at the

facility would be more appropriate than piecemeal replacement of the forms in the existing O&M plan.

Equipment # CM-1201 A/B

7. Emergency Shutdown (ESD)

NOTE ESD of the Gas Reinjection Facility can be initiated from any of the 7 pull stations located 

throughout the facility or from 1 push button station located in the Control Room. The 

Fire, H2S and LEL detection systems will also initiate an ESD. Both systems will 

shutdown all the reinjection compressors, isolate the inlet area and depressure the facility.

NOTE The ESD pull stations located throughout the facility are easily identified by the red and 

white stripes painted on the building or pipe rack support beams.

7.1. Reinjection Facility ESD:

7.1.1. ESD Station One push button station is located inside the Control Room above 

the Fire, H2S and LEL Detection System's readout panel is located on the South 

wall of the Rosemount panel inside the MCC Control Room. 

7.1.2. ESD Station Located on a pipe rack support beam on the southeast corner of the 

Acid Gas compressor building.

7.1.3. ESD Station Located outside between the Control Room and the MCC building.

7.1.4. ESD Station Located on the north wall outside of the Inlet Area's Air Compressor 

building.

7.1.5. ESD Station Located on a building support beam on the northwest corner of the 

HOS-6 Compressor building.

7.1.6. ESD Station: Located on a building support beam on the northwest corner of the 

HOS-4 Compressor building.

7.1.7. ESD Station: Located on cooler fan support beam on the southeast corner of the 

HOS-4 Compressor's Cooler Fan bay.

7.2 Fire, H2S and LEL Detection Systems ESD:

7.2.1. Fire: There are 10 Fire Detection sensors located throughout the facility. Any 

detection by either of these sensors will initiate an audible alarm, ESD’s 

reinjection facility, automatically isolating the inlet area and depressize the facility.

7.2.2. H2S: There are 23 H2S Detection sensors located throughout the facility. Any 

detection by either of these sensors at 10 PPM H2S will initiate an audible alarm 

and illuminate a "blue" beacon light. Any detection by either of these sensors at 

50 PPM H2S will initiate an audible alarm, illuminate a beacon light and 

shutdown all reinjection compressors, automatically isolating the inlet area and 

depressize the facility
