- Title V Application Revised GHG Emissions

Rahul,

I want to double check that the GHG GWP that you used in your 2/11/14 emission calculations are the

following:

GHG Pollutant GWP Factor

CO 2 1

CH 4 25

N 2 O 298

SF 6 22,800

Let me know if you used a different set of GWP.

- Title V Application Revised GHG Emissions

Hello Eva,

Per our phone discussion, please find the revised Greenhouse Gas (GHG) emission calculations for

Anadarko’s BlackHawk and BlackHornet PSD

- Title V Application. The revisions reflect the revised Global

Warming Potentials per EPA’s “Final Rule: 2013 Revisions to the Greenhouse Gas Reporting Rule and

Confidentiality Determinations for New or Substantially Revised Data Elements”

, which became

effective on January 1, 2014. As discussed, attached are:

 Revised GHG emissions summary page including GHG emissions from each equipment for all

operatin g scenarios

 Revised PTE table reflecting revised GHG emissions

While preparing the attached deliverable, Trinity found an error (i.e., wrong cell reference) in lbs/unit

GHG emission factor calculation for a flowback boiler (DR

- TP

- 22). The error was correc ted in the

attached submittals. Let me know if you have any questions or need clarification. Thanks for your help!
