Andrew,

I’ve provided some short answers to your questions below, but I’m not exactly sure what you’re

looking for here. Please let me know if these answers don’t address your needs.
(1) additional temporary employees (that) have been required since the time the Consent

Decree was entered,

Since acquiring the McElmo Creek Unit from Exxon Mobil approximately 12 months after

the Consent Decree was entered, Resolute has not utilized additional temporary

employees. We have increased the number of permanent, full-time staff dedicated to

operation of the McElmo Creek Unit by 85 percent. This includes the addition of facility

maintenance, electrical and engineering specialists that provide valuable expertise which

was not immediately available onsite in the past. We have also continued to utilize

contractors to supplement employee manpower and expertise as needed.

(2) any need to increase infrastructure resulting from this permitting action, and

Since acquiring the facility, Resolute has spent more than $15 MM on additional

compression and facility upgrades designed to increase compressor reliability, thereby

minimizing emissions from the flare. Resolute is currently investigating the possibility of

further increasing compression reliability by replacing the existing reciprocal

compressors with variable speed screw compressors. However, this project is still

prospective in nature and no capital expenditures have been committed. 

(3) anything additional about how the existing employee base already serves the flare

operations and maintenance?

Operations and maintenance of the McElmo Creek Unit facility is carried out by an

employee base that includes a variety of technical professionals and support staff who

ensure that the flare is functioning correctly and who work to minimize flare emissions by

maximizing compressor reliability. This includes Plant Technicians and the Plant

Supervisor who monitor the day to day operation of the flare; the Maintenance Foreman

and Facilities Engineer who oversee maintenance and repair services for the flare; and

the Automation Supervisor and Electricians who maintain the monitoring and

measurement systems associated with the flare.

Hi Dwight,

What we have under the growth impacts info is generally okay. However, given that the flare is in

existence and the consent decree entered for some time, I've been asked to provide a bit more
context. Can you please confirm and/or update whether (1) additional temporary employees have

been required since the time the Consent Decree was entered, (2) any need to increase

infrastructure resulting from this permitting action, and (3) anything additional about how the

existing employee base already serves the flare operations and maintenance? Please let me know

if you have any questions. I’m including Shirley in the cc because she is managing the growth

analysis segment. Thanks.
