3 PROJECT LOCATION

Anadarko ’s project is located on the OCS in the Eastern Gulf of Mexico. The drilling sites are located 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.

4 PROJECT DESCRIPTIO N

The proposed project will mobilize the Transocean Discoverer Spirit and associated support vessels. The support vessel s may consist of supply boats to transport personnel and supplies, and a combination of a tug boat, a barge, and a stimulation vessel f or well completion activities. , up to two support vessels to transport personnel and supplies, and up to three support vessels for well completion

. The proposed project will consist of three phases : the drilling phase, the well completion phase, and the production well maintenance phase. The operation will last no more than two years, and operate no more than 208 calendar days per year. Anadarko will conduct drilling activities at multiple locations within the Eastern Gulf of Mexico area described in Sec tion 3, Project Location, of this permit. This permit does not authorize the establishment of any permanent production facilities.

Air pollutant emissions generated from the project include carbon monoxide (CO), oxides of nitrogen (NO x ), particulate matte r (PM), particulate matter with an aerodynamic diameter less than 2.5 microns (PM 2.5 ), particulate matter with an aerodynamic diameter less than 10 microns (PM 10 ), sulfur dioxide (SO 2 ) and volatile organic compounds (VOC) (known as criteria pollutants), as well as other regulated air pollutants, including greenhouse gases. VOC and NO x are the measured precursors for the criteria pollutant ozone, and NO x and SO 2 are measured precursors for PM 2.5 . Based on emissions estimates and applicable permitting thresho lds

, the project is subject to the PSD and title V programs and has significant emissions of NO X , CO, PM, PM 10 , PM 2.5 , and VOC. In addition, the Discoverer Spirit is an area source of hazardous air pollutants pursuant to 40 CFR 63 subpart ZZZZ.

The Discover Spirit emission units can be found in Table 1. Additional units on the s timulation v essel that will be used for OCS activ i t i es are shown in Table 2. Table 3 lists the representative support vessels

.Anadarko OCS

- EPA

- R40015 0 9 / 15 03 /2014 4

Support vessels operating within 25 miles of th e OCS source will include supply boats (work or crew boat), an anchor handling boat, and support vessels used during well completion activities that run marine diesel engines.

The information provided in Tables 1 through 3 is for description and identifi cation purposes and does not establish operating limits.

. Data collected prior to issuance of this permit may be used with written EPA approval. After three annual/periodic stack tests of the same drilling vessel, stack test frequency may be reduced upon written approval by the EPA

.
6.7.1.3.1.3.2 Each stack test shall be con ducted at three different

loads spanning the expected range of operations.

6.7.1.3.1.3.3 During each test run, the permittee shall monitor and

6.7.1.3.1.3.4 The permittee shall prepare a graph of engine load

versus emission rates expressed in g/kW

- hr for each engine. Plot the engine load as the independent (or x) variabl e and the pollutant emission rates as the dependent (or y) variable for each load point tested. Construct the graph by drawing straight

- line segments between each load point. Draw a horizontal line to the
y

- axis from the minimum load point tested.Anadarko OCS

- R40015 0 9 / 15 03 /2014 28 6.7.1.3.1.3.5 The perm ittee shall use the load information with the

graph of engine load versus emission rates to determine the emission rate in g/kW

- hr for each engine load recorded. Linear interpolation shall be used to determine the emission rate when the actual load falls b etween two tested load points, the permittee shall use linear interpolation between the two load points to determine the emission rate . When the engine load exceeds the maximum load measured during the stack testing, the g/kW

- hr emission rate obtained for the highest load point tested during the most recent stack test may be used. When records of engine load are not available, the highest g/kW

- hr emission rate calculated for all the load points tested during the most recent stack test may be substituted. Th e average emission rate for each hour of operation from all individual emission rate results recorded during the hour will then be calculated
