U.S. Environmental Protection Agency

Outer Continental Shelf Air Permit OCS-EPA-R4015

for Anadarko Petroleum Corporation 

Public Comment Period: June 20, 2014 -July 21, 2014

The United States Environmental Protection Agency (EPA) is seeking public comment on a draft 

Clean Air Act (CAA) Outer Continental Shelf (OCS) air permit for Anadarko Petroleum Corporation 

(Anadarko), 1201 Lake Robbins Drive, The Woodlands, Texas 77380. Anadarko has applied for an OCS 

air permit pursuant to section 328 of the Clean Air Act (CAA) from EPA Region 4. The proposed air 

permit will regulate air emissions from a proposed exploratory drilling operation within the Eastern Gulf 

of Mexico (EGOM) of the OCS. The proposed project will mobilize the Transocean Discoverer Spirit, 

up to two support vessels to transport personnel and supplies, and up to three support vessels for well 

completion. The operation will last no more than two years, and operate no more than 208 calendar days 

per year. The proposed project is for exploratory drilling and well completion only and does not include

the establishment of any permanent production platforms.

Anadarko proposes to conduct exploratory drilling at multiple sites within the Eastern Gulf of 

Mexico. The drilling area is located on the OCS east of longitude 87.5, west of the Military Mission 

Line (86°41’ west longitude), at least 100 miles from the Louisiana shoreline, and at least 125 miles 

from the Florida shoreline. 

EPA Region 4 is the agency responsible for implementing and enforcing CAA requirements for 

OCS sources in the Gulf of Mexico east of longitude 87.5o. Pursuant to section 328 of the CAA (42 

U.S.C. § 7627) and the air quality regulations applicable to OCS sources set forth in Title 40, Code of 

Federal Regulations (CFR), part 55, this project is required to obtain an OCS air quality permit and is 

subject to Prevention of Significant Deterioration (PSD) requirements that apply to major sources and 

also to title V operating permitting requirements. Anadarko must apply best available control technology 

(BACT), among other requirements, for emissions of NOX, CO, VOC, PM, PM2.5, and PM10. The 

maximum potential annual emissions in tons per year for each drilling vessel and its support vessels are 

detailed in the application materials and preliminary determination/statement of basis. Potential annual 

emissions are also summarized in the project fact sheet. 

Permit Documents: EPA has prepared a draft permit for public comment, as well as a 

preliminary determination/statement of basis document that explains the permit conditions. These 

documents are available on EPA Region 4’s website at:

4, Air Permits Section APTMD, 61 Forsyth Street, SW, Atlanta, GA 30303 Attn: Rosa Yarbrough. An 

extension of the 30-day comment period may be granted if the request for an extension is submitted 

during the 30-day public comment period and it adequately demonstrates why additional time is required 

to prepare comments. 

Any interested person may submit written comments on the draft permit during the public 

comment period. If you believe that any conditions in the permit are inappropriate, you must raise all 

reasonably ascertainable issues and submit all reasonably available arguments supporting your position 

by the end of the comment period. Any documents supporting your comments must be included in full 

and may not be incorporated by reference unless they are already part of the administrative record for 

this permit or consist of state or federal statutes or regulations, EPA documents of general applicability, 

or other generally available reference materials. Comments should focus on the draft air quality permit.

If you have comments regarding offshore leasing, non-air quality impacts, drilling safety, discharge, or 

other similar issues not subject to this public comment period, you should submit them during the 

leasing and approval proceedings of the Bureau of Ocean Energy Management, which is the lead agency 

for offshore drilling. 

All comments will be included in the administrative record without change and will be made 

available to the public, including any personal information provided, unless the comment includes 

Confidential Business Information or other information whose disclosure is restricted by statute. 

Information that you consider Confidential Business Information or otherwise protected must be clearly 

identified as such and should not be submitted through email. If you send email directly to EPA, your 

email address will be captured automatically and included as part of the public comment. An email or 

postal address must be provided with your comments if you wish to receive direct notification of EPA’s 

final decision regarding the permit and response to comments submitted during the public comment 

period. All timely comments on the draft permit will be considered in making the final decision. EPA

will respond to all significant comments on the proposed permit and may summarize and group similar 

comments in our response. EPA will not respond to individual commenters directly.

Public Hearing: Requests for a public hearing on the draft air permit must be in writing and 

received by EPA by July 14, 2014. Requests should be sent by email to R4OCSpermits@epa.gov or by 

mail addressed to: USEPA Region 4, Air Permits Section, 61 Forsyth Street, SW, Atlanta, GA 30303, 

Attn: Rosa Yarbrough. EPA will hold a public hearing on the draft air permit pursuant to 40 CFR 124.12 

if the Agency determines that there is a significant degree of public interest in the draft permit. Requests 

for a public hearing must state the nature of the issues proposed to be raised in the hearing. If a public 

hearing is held, you may submit oral and/or written comments on the proposed permit at the hearing. 

You do not need to attend the public hearing to submit written comments. If EPA determines that there 

is a significant degree of public interest, EPA will hold a public hearing from 5:30 to 7:00 pm on July 

31, 2014, at: West Florida Public Library, 239 North Spring Street, Pensacola, Florida 32502, (850) 436-

5043.

If a public hearing is held, the public comment period will automatically be extended to the close 

of the public hearing. If no timely requests for a public hearing are received, or if EPA determines that 

there is not a significant degree of public interest, a hearing will not be held. Such an announcement will 

be emailed to our OCS public notice list and posted on EPA’s website identified above, or you may call 

EPA at the contact number above to determine if the hearing will not be held.

If a public hearing is held, EPA staff will be available prior to the hearing, from 4:00-5:30 pm to 

answer questions and provide information on this proposed action during an informal public information 

session. You are not required to attend the information session to comment at the public hearing, and 

you may also obtain additional information about the project at EPA’s website listed above. 

Final Determination: EPA will make a final decision to issue the permit or to deny the 

application for the permit after the Agency considers all comments on the draft air permit. Notice of the 
final decision shall be sent to each person who has submitted written comments or requested notice of 

the final permit decision, provided EPA has adequate contact information.
