### Rahul,

We have deemed the applications complete. (I was planning on sending you the signed copy

this afternoon, but I seem to be having some IT issues.) However, the completeness letter for

the two applications was signed today, and should be in the mail.

- BlackHawk/BlackHornet

Rahul,

We keep trying to catch each other concerning the remaining air quality impact concerns from the

comments/clarification requests provided in the incompleteness letter for the BlackHawk and

BlackHorn et PSD permit applications. Similar to the Bob Douglas application, the provided responses to

our incompleteness comments did not resolve all items.

To facilitate our discussion and completing the records for these applications, the following provides

the remaining comments not resolved by Anadarko’s 12 November 2013 response.

19. Provide reason the impact assessment using a single supply boat is appropriate given simultaneous

operation of multiple supply boats is planned.

The total fuel limit pr ovided for all utilized supply boats is provided as justification. The emissions from

the modeled supply boat was indicated to be based on the proposed fuel limit so the impact modeling

properly represents the impacts from one or more supply boat operatio ns.

The fuel limit for the all supply boats is based on 24

- hour and annual periods. Considering the short

term standards (e.g. 1

- hour NAAQS), the only way the modeled single supply boat would represent the

worst

- case supply boat impact would be if the fuel limit included an hourly value and the emissions used

in the modeling were based on the hourly fuel limit consumed by the single boat.

The application indicates the shortest period for supply boat fuel limit was 24

- hours. Multiple supply

boats could operate under the 24

- hour fuel limit, although not for the full 24

- hours period, producing

larger hourly emissions and greater impacts than that associated with a single boat.

21. Ozone data used in CALPUFF modeling analyse s

The use of ozone data representative of the modeling domain and/or the PSD Class I area is

appropriate. Data acquired at Sumatra, FL would be appropriate for St. Marks and Bradwell Bay Class I

impact analyses. The appropriateness for application at t he Breton PSD Class I area has not been

addressed.

22. Screening ambient concentration levels for soils and vegetation.

The EPA referenced screening ambient concentration levels were not addressed in the response. Rather

the response reiterated the fa ct that the provided qualitative conclusion was based on the Secondary

NAAQS. Comparison of the screening levels in “A Screening Procedure for Impacts of Air Pollution

Sources on Plants, Soils, and Animals” were not provided.24. Confirm the Breeze soft ware used the unmodified versions of the regulatory CALPUFF modeling

system.

The response indicates the approved versions of the CALPUFF modeling system were

used. Confirmation is needed that the BREEZE modeling system uses for this analysis incorporate s the

unmodified regulatory versions of CALMET, CALPUFF, and CALPOST.

I suggest we discuss these items and the needed additional information before you prepare any

response.

Thanks...sjk
