### 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.

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 a nd LEL detection systems will also initiate an ESD. Both systems will shutdown all the reinjection compressors, isolate the inlet area and depressurize 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 (PB1) One push button station is located inside the Control Room above the Fire, H2S and LEL Detection System's readout panel is loc ated on the South wall of the Rosemount panel inside the MCC Control Room.

7.2 Fire, H2S and LEL Detection Systems ESD:

7.2.1. Fire : There are 14 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 20 H2S Detection sensors located throughout the facility. Any detection by either of these sensors at 10 PPM H 2S 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 i nlet area and depressize the facility

7.2.3. LEL : There are 8 LEL Detection sensors located throughout the facility. Any detection by either of these sensors at 20 % LEL will initiate an audible alarm.

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 detecti on systems will also initiate an ESD. Both systems will shutdown all the reinjection compressors, isolate the inlet area and depressurize 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.

7.2 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 t he 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 dete ction 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 facilityResolute Natural Resources McElmo Creek Unit Gas Reinjection Facility Operating Procedure File Name AGCOMP Authorized Page 7 of 9 ACID GAS COM PRESSORS "A" and "B" Draft only Equipment # CM

7.2.3. LEL : There are 8 LEL Detection sensors located throughout the facility. Any detection by either of these sensors at 30 % LEL will initiate an audible alarm. Any detection by either of these sensors at 50 % LEL will initiate an audible alarm and shutdown all reinjection compressors, isol ate the inlet area and depressure the facility

7.3. Acid Gas Compressor ESD.

7.3.1. Local ESD . Trip individual compressor ESD by pressing 'Stop' button on local control panel to shut down that compressor only.

8. Safety Shutdown.

8.1. Any condition below causes a safety shutdown of the compressor:

• ESD pull stations

• Fire, H2S, and LEL Detection systems

• Low instrument air header pressure

• Electrical power failu re

• Low discharge pressure on either the 1st, 2nd, 3rd or 4th stage cylinders

• High discharge pressure on either the 1st, 2nd, 3rd, or 4th stage cylinders

• High discharge temperature o n either of the 1st, 2nd, 3rd or 4th stage cylinders

• High level in either of the 1st, 2nd, 3rd or 4th stage suction scrubbers

• Low 1st stage suction pressure

• High 1st stage suction pressure

• Crank case oil pressure

• Oil level low

• No flow cylinder lubricator on either of the 1st, 2nd, or 3rd stage cylinders

• No flow cylinder lubric ator on the 4th stage cylinder

• Low cylinder lube oil level

• Jacket Water 1st, 2nd, 3rd low pressure

• Jacket Water pressureResolute Natural Resources McElmo Creek Unit Gas Reinjection Facility Operating Procedure File Name AGCOMP Authorized Page 8 of 9 ACID GAS COM PRESSORS "A" and "B" Draft only Equipment # CM
