Re: Response to EPA Incompleteness Determination

Statoil Gulf Services, LLC

Title V and PSD Permit Application

OCS Drilling and Exploration Activities

Dear Mr. Worley:

Statoil Gulf Services, LLC (Statoil) submitted a Title V and Prevention of Significant

Deterioration (PSD) permit application for proposed exploratory drilling in the Outer Continental

Shelf (OCS) in the eastern Gulf of Mexico to EPA on September 5, 2012. On October 10, 2012

EPA responded with a letter of incompleteness and a request for additional information required

to continue the application review process. On behalf of Statoil, ENVIRON International

Corporation (ENVIRON) is providing a respon se to each of the twenty-two completeness

comments included in the letter. All available supporting documentation is included herein or as

an attachment to this response letter.

Please be aware that Statoil is waiting for vendor data that will affect the response to some of

the completeness comments. A vendor will be providing Statoil with a detailed SCR quote for

the Developer main generator engines, and Statoil should be receiving any available emission

certification documents for the two emergency air compressor engines aboard the Discoverer

Americas . Until Statoil has the emission certification documents, the final emission inventory

and dispersion modeling cannot be updated. We have included notes in the responses below

that require the SCR quote and/or the emission certification documents for completeness. We

will provide detailed responses to the remain ing comments as soon as we have received data

from the vendors.

### USEPA Region 4 2 December 7, 2012

Modeled Operational Scenarios

Comment 1. Please provide data supporting the conclusion that the proposed

dispersion modeling scenario produces the maximum impacts for the modeled

pollutants for the full range of planned operating scenarios. Please provide the basis or

explanation for the statement that operation at less than the maximum proposed loads

with corresponding changes in stack release parameters would not result in higher

model-predicted impacts.

As described further in response to Comment 16, Statoil determined the worst-case operating

scenarios resulting in reasonable worst-case emissions for each drilling vessel and support

fleet. In addition, Statoil contends the worst-case emissions do result in the worst-case

modeled impacts at the source-receptor distances relative to this project. Note, the nearest

receptors are located more than 200 km from the source; therefore, stack parameters and

building downwash will not significantly affect modeled results.

A plume’s initial rise in both AERMOD and CALPUFF is characterized in terms of the stack

parameters (temperature, velocity, etc.) and dow nwash parameters (building dimensions, as

processed by BPIP). For small source-receptor distances, the initial plume rise can have a

significant effect on predicted concentrations. For low initial plume rise, the plume centerline is

closer to the ground and results in higher predicted concentrations at nearby receptors.

However, at the source-receptor distances relevant to the current modeling effort (>200 km), the

initial plume rise has little effect on predicted concentrations. At these down-wind distances, the

puffs (plume) have expanded to fill the Planetary Boundary Layer (PBL, often called the mixed

layer or mixing layer). The chemical species are well-mixed throughout the PBL, and the details

of the release point have an insignificant effect on model-predicted concentrations. This is why

the Protocol for this project specified that no building downwash would be included in the

modeling. Similarly, differences in stack te mperature and velocity at varying engine loads have

an insignificant effect on model results at su ch distances. At these distances, predicted

concentrations are primarily controlled by the emission rate. The choice of engine loads that

results in the maximum short-term emission rate is addressed in the response to Comment 16.

Modeled Emissions

Comment 2. Tables 6.2.3-12 and 6.2.3-13 of the permit application provide the total

support vessel emissions in each volume source modeled. Please provide the emission

rates for each support vessel used in developing the ambient impact modeled emissions

provided in these tables.

Support vessel emission calculations are provided as Attachment 1 of this response letter.

Please note that at the time of the September 2012 application, Statoil was provided with

information stating the engines aboard the Peyton Candies vessel were certified EPA Tier 2;

however, Statoil recently determined the Peyton Candies OSV engines are

40 CFR 1043/MARPOL compliant but not certified to EPA Tier 2 standards. As a result of the

new emission information, the proposed emission rates for the OSV engines are higher than

### USEPA Region 4 3 December 7, 2012

presented in the original application, and the annual operating hours for the OSV engines have

been lowered from the values presented in the original application.

Detailed support vessel emission rate calculations will be provided to EPA in a revised Air

Quality Impacts Analysis document after we receive the remaining supporting data for the

Discoverer Americas emergency air compressor engines from the vendor and make any

necessary updates to the dispersion modeling analysis.

Comment 3. Please confirm that the modeled stack parameters for each emission unit

were those producing the worst-case impacts for all operating characteristics.

See the response for Comment 1. The initial pl ume rise (controlled by the stack parameters)

has an insignificant effect on predicted concentrations at the source-receptor distances relevant

to this project.

Fuel Usage and Modeled Emissions

Comment 4. The long-term emission rates for the support vessels were based on

adjusted fuel usage and proposed annual run times. Please provide each support

vessel’s adjusted fuel usage and proposed run times along with the basis for these

values in the emissions calculation contained in Appendix B of the application.

The proposed annual operation data for the OSVs and crew boats are based on historical

support vessel operation data collected by Statoil. Fuel use calculations for the OSVs and crew

boats are based on the estimated annual engine operation and diesel fuel properties. Statoil

calculated proposed annual fuel usage limits for OSV engines and crew boat engines when

within 25 nautical miles of the drill vessel of 622,416 gallons per year and 252,195 gallons per

year, respectively. Fuel use calculations fo r the OSV and crew boat engines are provided in

Tables 4-1 and 4-2 below. Please note that Statoil has revised the fuel usage calculations for

the OSV based on recently received engine certification information discussed below.

At the time of the September 2012 application, Statoil was provided with information stating the

engines aboard the Peyton Candies vessel were certified EPA Tier 2; however, Statoil recently

determined the Peyton Candies OSV engines are 40 CFR 1043/MARPOL compliant but not

certified to EPA Tier 2 standards. As a result of the new emission information, the proposed

emission rates for the OSV engines are higher than presented in the original application, and

the annual operating hours for the OSV engines have been lowered from the values presented

in the original application. These changes result in a proposed increase in OSV emission rates

than previously proposed. The updated OSV emission rates are presented in response to

Comment 17, and the revised OSV operating hours are presented in Table 4-1 below.

### USEPA Region 4 5 December 7, 2012

Comment 5. Section 6.4.3 indicates the maximum short-term emission rates for the

support vessels were based on the maximum 24-hour fuel usage. Whereas, Section

6.2.2. indicates that short-term emissions from the vessels were based on maximum

engine operation (i.e. 100 % load). Please clarify the basis upon which the fuel usage

was calculated for the support vessels with respect to the engine loads.

Maximum short-term emission rates (hourly and daily) for the OSV and crew boat engines are

based on all engines operating simultaneously at 100 percent load for 24 hours per day. This

scenario represents the maximum anticipated hourly emission rate for the support vessels,

which is used for modeling against the short term hourly ambient air standards and for Class I

visibility (24-hr). Annual fuel use calculations for OSVs and crew boats are based on long-term

engine operation data (engine load and hours of operation) available from the OSV and crew

boat operators and a conversion between engine output and diesel fuel input. Tables 4-1 and

4-2 of this response letter provide the detailed annual fuel use estimate for each engine on the

OSV and crew boat.

Comment 6. It is unclear how the proposed fuel limitations and annual run times

presented in Section 3 of the application are used in conjunction with the modeled

emission results presented in Section 6 and Appendix B. Please clarify the basis upon

which the fuel usage was calculated for the drilling vessels and support vessels with

respect to the engine loads.

Fuel use calculations for the drill vessels, OSVs, and crew boats are based on the estimated

annual engine operation for each vessel and diesel fuel properties. Fuel use calculations for the

OSV and crew boat engines are provided in response to Comment 4, (see Tables 4-1 and 4-2

of this response letter). Statoil calculated proposed annual fuel usage limits for the Developer

and Discoverer Americas drilling vessel engines of 2,650,333 gallons per year and

2,181,967 gallons per year, respectively. Fuel use calculations for the Developer and

Discoverer Americas drilling vessel engines are provided in Tables 6-1 and 6-2 below.

Please note, the short-term emissions and long-term emissions are calculated based on

different engine load scenarios; therefore, short- term emissions are not si mply multiplied by the

engine hours of operation per year to calculate annual emission rates. Drill vessel, OSV, and

crew boat operators provided both short-term and long-term engine operation scenarios

(number of engines operating and the engine load) for each vessel. Annual fuel usage

calculations are based the long-term engine operating scenarios for each vessel and an AP-42

conversion factor to calculate fuel use per unit of engine output. The long-term emission

calculations for each vessel are used to calculate the proposed fuel usage limitations, and the

emission calculations correspond to the emissi on rates used in the dispersion modeling

analysis.

Project Impact Assessment

Comment 7. Although the nearest modeled receptors were indicated in Section 6.1 to be

25 miles seaward of the state's seaward boundary. Section 6.3 Project Impact

Assessment indicates that the impacts were performed at discrete shoreline receptors.

This section also indicates that the significant monitoring concentration (SMC)

assessment was performed at the shoreline receptors. [Note: The modeled

concentrations provide in Table 6.3.1-1 for comparison to both the significant impact

level (SIL) and SMC do not indicate different receptor locations.] The significant impact

and SMC assessments should be performed at the same nearest PSD Class II receptors.

Please provide revised analyses or further explanation for the use of different receptor

locations.

The Application incorrectly used the term “shoreline receptors” interchangeably with the term

“25-mile receptors”. Inspection of the CALP UFF modeling files shows that only the 25-mile

receptors were used for all relevant Class II asse ssments. A revised Air Quality Impact Analysis

document containing the correct “25-mile recept or” terminology will be provided to EPA as soon

as we receive the remaining supporting docum entation from the vendor required to update

emission estimates and make any necessary updates to the dispersion modeling analysis.

Comment 8. The support vessels for both the short-term and long-term standards were

modeled as a series of 10 volume sources in a line from the drilling location to 25 miles

in the direction of the nearest PSD Class I area (Breton Wilderness). This is acceptable

for the annual average ambient standard, but is not the worst-case location for the 1-hour

standard. Modeling these vessels at the end of the required 25-mile pathway in the

direction of the closest Class II receptor would be more appropriate for worst-case

impacts. Please provide a revised analysis or further explanation of how the approach

used is appropriate for a worst-case analysis.

Typical support vessels (Peyton Candies, Claire Candies) have an average speed of about

8 knots (15 km/hr). Given that the 25-mile radius is about 40 km, and that during most of the

traverse of that distance the vessels would likely be traveling at least their average speed, the

ten volume sources representing the support vessels should be spread over one third, rather

than the full, of the 25-mile pathway from the nearest port to the drill vessel. A revised Air

Quality Impact Analysis document will be provi ded to EPA as soon as we receive the remaining

supporting documentation from the vendor requi red to update emission estimates and make any

necessary updates to the dispersion modeling analysis.

### USEPA Region 4 9 December 7, 2012

Comment 9. The application indicates that the 2008 version of the Federal Land Manager

Air Quality Related Workgroup (FLAG) Phase I Report procedures were used to assess

project impacts. However, revised 2010 procedures are available. Please clarify which

procedure was used for the analysis. If the 2008 version was used, please provide the

rationale for using the older version.

ENVIRON used FLAG 2010 procedures but the September permit application mistakenly

referenced the 2008 version. ENVIRON will correct this typographical error in the revised Air

Quality Impact Analysis document to be subm itted at a later date as noted previously.

PSD Class I Air Quality Related Values (AQRV) Analysis

Comment 10. The FLAG recommended default options were used for the AQRV analysis.

It was also indicated in the application that NOx chemistry was used. These options are

appropriate for the AQRV assessment but not for the PSD Class I increment assessment.

Please clarify if the EPA recommended CALPUFF version and default options were used

to assess project Class I concentration impacts.

A CALPUFF control file contains an option (MREG) that instructs CALPUFF to test if a set of

options “conform to the USEPA Long Range Transport (LRT) guidance.” This set of options is

designed to assure compliance with the IWAQM Phase 2 Summary Report 1 

### , and is listed in that

document’s Appendix B with a recommended value MREG = 1. This in turn assures that

CALPUFF uses the MESOPUFF-II Chemistry, and includes wet and dry deposition and

associated depletion. The introduction to Appendix B of the document indicates that this

Guidance is relevant for “not only concentrati on impacts, but also deposition flux impacts and

visibility impacts.” This report was issued by EPA/OAQPS, and was co-authored by

EPA/AQMD, the National Park Service, and the USDA Forest Service.

The methodology and CALPUFF settings in this guidance have been used for PSD applications

involving Class I areas for the last fifteen years. To ENVIRON’s knowledge, every PSD

application since its issuance that involved a Class I area has followed this guidance.

Nonetheless, in an effort to expedite the current permitting process, a revised Air Quality Impact

Analysis document including the results of a separate CALPUFF run for the EPA, to address

Class I Area Increment, will be provided to EPA as soon as we receive the remaining supporting

documentation from the vendor required to update emission estimates and make any necessary

updates to the dispersion modeling analysis.

Comment 11. The results of the visibility extinction assessment exceeded the Federal

Land Manager (FLM) threshold of concern of five percent. Please provide the basis or

support for the statement that most of these days were likely impacted by natural

obscuration.

A revised Air Quality Impact Analysis document will be provided to EPA at a later date as noted

previously. The revised analysis will adequately address the results of the visibility extinction

assessment including any results that exceed the FLM threshold of concern of five percent.

Ozone Impacts

Comment 12. The project's NOx emissions are also an ozone precursor. Please address

the expected impacts of the project's NOx emissions on the ambient ozone levels.

A revised Air Quality Impact Analysis document will be provided to EPA at a later date as noted

previously. The revised analysis will include an ozone analysis.

Identification of Emissions Sources

Comment 13. Please clarify the emission units present on the two drilling vessels and

revise emission calculations if appropriate.

A summary of equipment present on the Developer and Discoverer Americas drill vessels is

presented in Tables 13-1 and 13-2 below, respectively. The Developer has electrically-powered

forklifts, but the Discoverer Americas has two forklifts with diesel engines. Both drilling vessels

have electrically-powered cranes and wireline units . Wireline units are operated by a third party

and Statoil will require the use of electric motors and not diesel engines for these units. The

cement unit engines on the Discoverer Americas will be required to use electric motors. Neither

drilling vessels are equipped with incinerators, nor does the Developer have diesel-powered air

compressor engines. The following tables include an updated equipment list for each drilling

vessel, including equipment that is electric-powered and not a source of emissions.

The Discoverer Americas main engine NO X 

### and CO emission factors were developed from New

Source Performance Standards (NSPS) for Stationary Compression Ignition Engines

(Subpart IIII) and main engine test data collected for certification with the International Maritime

Organization (IMO) MARPOL Annex VI emission standards. The IMO certification summary for

emission standard for engines of that size. Therefore, the annual CO emission factor for the

main engines is based on linear interpolation of the engine test data for 35 percent load, which

is the expected normal operating load for the main engines. The NSPS provides a NO X

### Where,

n = rated engine speed (in rpm)

Short-term Emission Factors

The maximum hourly emissions for the Discoverer Americas main engines are based on

operating 4 engines at 80 percent load. Therefore, the short-term NO X 

### and CO emission factors

are based on linear interpolation between the 100 percent and 75 percent engine load emission

factors to derive an emissions factor at 80 percent load.

Comment 15. Please provide engine test data, vendor supplied data, and any

certifications used to calculate emissions for the Developer and Discoverer Americas

.

Attachment 2 of this letter provides all available engine test data and emission certifications for

the two drill vessels, including:

 Discoverer Americas Main Engine IMO Emission Certification;

 Discoverer Americas Emergency Generator Engine IMO Emission Certification;

 Discoverer Americas Forklift Engine Nameplate EPA Nonroad Interim Tier 4 Emission

Certification;

 Developer Main Engine IMO Emission Certification;

 Developer Emergency Generator Engine IMO Emission Certification;

 Developer Cement Unit Engines Tier 2 Emission Certification;

 OSV Peyton Candies – Main Engine and Emergency Generator Engine – IMO Emission

Certifications; and

 Crew Boat Sybil Graham – Main Engines, Generator Engines, and Thruster Engines –

Tier 2 Emission Certification Documents.

Statoil is waiting to receive emission certification documents for the two emergency air

compressor engines (ACOMP), and will provide the certification data to EPA once we have

received the data.

### USEPA Region 4 15 December 7, 2012

Comment 16. As summarized above in comment 1, a limited number of main engines

operating at less than 100% load was selected to represent "normal" and "maximum

hourly" operating configurations for each operating scenario. However, emissions

should be based on worst case conditions to calculate the potential to emit and

maximum hourly NOx emissions. It is unclear if the emissions calculations included in

the application were based on a worst case scenario since NOx emission rates vary with

load in large marine diesel engines. Please provide the emission rate versus load data

that the vendor or Statoil has available and the engine operating configuration that would

result in a worst case NOx emission rate. Please note that this worst-case emissions

scenario may not be the same operating condition producing the worst-case impacts.

As noted in response to Comment 1, worse-case emissions do produce the worst-case impacts

at the source-receptor distances corresponding to this project. Therefore, Statoil worked closely

with the drilling vessel owners to determine the normal and worst case (maximum hourly)

operating scenarios for the engines aboard each vessel. Sections 3.2 and 3.3 of the original

application include a description of the engine loads and expected run times for the engines

utilized on the Developer and Discoverer Americas

.

Statoil obtained emission profiles for the main engines on the Discoverer Americas and the

Developerdrill vessels. Emission profiles include emission factors (gram pollutant per kilowatthour, g/kW-hr) at various engine loads (10, 25, 50, 75, and 100 percent). The Discoverer

Americas main engine emission profile is provided in Table 14-1 of this response letter, and the

Developer main engine emission profile is provided in Table 16-1 below. Each table presents

the NO X 

### and CO pound per hour emission rates for each engine load. While emission factors

are generally higher at lower engine loads, it would not be appropriate to utilize a higher factor

at a 10 percent load, for example, to an engine operating scenario where the engine is expected

to be operating at 80 percent load. Statoil determined appropriate operating scenarios for each

engine and then applied to emission factor corresponding to that particular engine load.

The drill vessel owners provided Statoil with conservative maximum hourly and typical “normal”

operating conditions (number of engines operating, the load on the operating engines, and the

number of engines on standby). Statoil combined the conservative hourly and long-term main

engine operating conditions with available NO X 

### emission data. As presented in Tables 14-1 and

16-1 of this response letter, the NO X 

### emission factors are based on maximum tested values,

interpolating between load test conditions, or NSPS emission limits. The selection of the NO X 

### emission factors is based on developing conservative emission rate estimates for the main

engines.

The operating scenarios represent reasonable operating conditions corresponding to average

annual (per campaign) or maximum short term (hourly) operations. There are no normal or

maximum operating scenarios where all six or eight main engines on either drilling vessel would

be operating simultaneously. Some engines are on standby for maintenance while others are

on standby to be available for contingency back-up plans. Similarly, it is not reasonable to

expect one of the main engines to operate at 100 percent load for any duration of time as the

### USEPA Region 4 16 December 7, 2012

engines are designed to operate at loads less than maximum design capacity, and standby

engines are readily available for use during heavy power demands such that no one engine

would bear an unrealistic load for any period of time to minimize safety concerns and engine

wear.

### Comment 17. Please clarify the rationale for selecting the offshore support vessel

Peyton Candies and the crew boat Sybil Graham as representative vessels including the

engine data referenced in the determination, the vendor data and certifications

referenced with respect to the emissions factors used in the emissions calculations, and

the relationship between the emissions calculations presented in the application and the

adjusted fuel usage.

As stated in the application, Statoil has access to various OSV and crew boats to support their

operations in the Gulf of Mexico. At the time of preparing the application, the Peyton Candies

(OSV) and the Sybil Graham (crew boat) represented the worst-case emission rates of the

available support vessels because these vessels have the highest total horsepower and

associated emissions compared to other available OSVs or crew boats. Statoil reserves the

right to use other support vessels and will confirm engine emission rates will be less than or

equal to the worst-case vessel emissions provided in the application and this response letter.

Maximum hourly emissions for the support vessels are based on the OSV and crew boat

engines operating simultaneously at 100 percent load, which represents the worst-case

emission scenario. The hourly emission calculations are very conservative because it is very

### USEPA Region 4 17 December 7, 2012

unlikely that all support vessel engines (main engines, emergency generator engines, etc.)

would operate at 100 percent load at the same time. Maximum daily emission rates are based

on the hourly emissions (all engines at 100 percent load) and all support vessel engines

operating for 24 hours per day.

Annual support vessel engine emissions are based on long-term engine operation data (engine

load and hours of operation) available from the OSV and crew boat operators and a conversion

between engine output and diesel fuel input. Tables 4-1 and 4-2 of this response letter provide

the long-term engine operation data for each engine on the OSV and crew boat.

Engine emission data supporting the emission calculations for the support vessels are provided

in Attachment 2 of this response letter. Please note that at the time of the application, Statoil

was provided with information stating the engines aboard the Peyton Candies vessel were

certified EPA Tier 2; however, Statoil recently found the Peyton Candies OSV engines are

40 CFR 1043/MARPOL compliant, which requires certification to a lower emissions standard

than EPA Tier 2. Updated OSV engine annual operating hours and emission factors (NO X 

### and

particulate matter) are presented in Table 17-1 and 17-2 below, and an updated set of Part 71

forms for the Developer are provided in Attachment 3 of this response letter. ENVIRON will

provided EPA with updated Part 71 forms for the Discoverer Americas upon completion of

emission calculations that will be revised to inco rporate new emissions data that is currently

pending as noted previously.

A revised Air Quality Impact Analysis document will be provided to EPA at a later date as noted

previously. The revised analysis will clarify that the modeling assessment is based on

maximum hourly, daily, and annual emission rates calculated as described above. The longterm emission calculations for each vessel are used to calculate the proposed fuel usage

limitations, and the emission calculations correspond to the emission rates used in the

dispersion modeling analysis.

### Fuel use calculations for the OSV and crew boat are based on annual engine usage and diesel

fuel properties. Statoil is providing the suppor t vessel annual fuel usage data to EPA to assist in

the development of permit conditions for tracking OSV and crew boat operations during the

drilling campaign. Statoil calculated annual fuel usage limits for OSV engines and crew boat

engines when within 25 miles of the drill vessel of 622,416 gallons per year and 252,195 gallons

per year, respectively. Fuel use calculations for the OSV and crew boat engines are provided in

response to Comment 4, Tables 4-1 and 4-2 of this response letter. The long-term emission

calculations for each vessel align with the proposed fuel usage limitations and with the emission

rates used in the dispersion modeling analysis.

### USEPA Region 4 19 December 7, 2012

Identification of Applicable Requirements

Comment 18. In Section 4.2.3 the applicant has identified the applicable requirements of

subpart IIII for each engine and noted the Tier rating of each class of engines. However,

there is no supporting documentation included with the application. Please provide

copies of these certificates.

Attachment 2 of this response letter contains a ll available emission certification documents.

Emission certifications are available for all but three engines aboard the Discoverer Americas

drill vessel. Statoil is waiting to receive emission certification documents for the two emergency

air compressor engines (ACOMP), and will provide the certification data to EPA once we have

received the data.

At the time of the September 2012 application, Statoil was provided with information stating the

engines aboard the Peyton Candies vessel were certified EPA Tier 2; however, Statoil recently

determined the Peyton Candies OSV engines are 40 CFR 1043/MARPOL compliant but not

certified to EPA Tier 2 standards. Under 40 CFR 55.7 the Administrator or the delegated

agency may exempt a source from a control te chnology requirement if compliance with the

control requirement is technically infeasible or will cause an unreasonable threat to health and

safety. Engine-specific information for the emergency generator engine is provided below with

additional information to request the 40 CFR 55.7 exemptions from the NSPS Subpart IIII

emission limit requirements.

Discoverer Americas Emergency Generator Engine (EGEN)

The EGEN unit is a post-2007 non-fire pump emergency engine with a displacement greater

than or equal to 10 L per cylinder. Therefore, the engine is subject to 40 CFR 60.4202(e)(1),

which requires compliance with the emission standards in 40 CFR 94.8; specifically, this engine

must comply with the following emission limits: NMHC+NO X 

### = 9.8 g/kW-hr; CO = 5.0 g/kW-hr;

and, PM = 0.50 g/kW-hr. To demonstrate compliance with the emission limits 40 CFR

60.4211(c) requires the owner/operator to purchase a certified engine. Statoil received the

available emission certification documents for the EGEN unit and determined the engine is not

certified to Tier 2 engine standards.

40 CFR 55.7 Exemption Request

The emergency generator engine was originally sized to meet the required loads of emergency

generation aboard the Discoverer Americas during its initial design process and as such the

engine was installed to fit those needs. The NSPS subpart specifically requires the

owner/operator to purchase a certified engine, which does not allow the engine manufacturer to

revise the engine certification to Tier 2 levels if additional emission controls were added to the

engine.

Since a Tier 2 certified engine is the only compliance option available to meet the requirements

of 40 CFR 60 Subpart IIII, a new engine would have to be purchased by the vessel owner.

### USEPA Region 4 20 December 7, 2012

Under the criteria for exemption of a source fr om a control technology requirement specified at

55.7(b)(4)(i), Statoil believes that the purchase of a new engine is considered technically

infeasible. Therefore, Statoil requests exempt ion from the requirements of 40 CFR 60 Subpart

IIII for the emergency generator engine.

As documented in Table 18-1 below, the emergency engine potential to emit basis is below the

Tier 2 emissions levels for all pollutants except for NO X 

### +NMHC. Therefore Statoil is only

proposing to offset NO X 

### + NMHC emissions.

Notes:

a – Vendor supplied CO emissions da ta for the EGEN (0.26 g/kW-hr) are

less than the Tier 2 emission limit (5.0 g/kW-hr); therefore, both

proposed and Tier 2 emissions are calculated based on the vendor

data.

b – No vendor data are available for particulate matter emissions. Statoil

based proposed emission calculations on available AP-42 emission

factors for large diesel engines. The AP-42 PM emission factor (0.30

g/kW-hr) is less than the Tier 2 emission limit (0.5 g/kW-hr).



### In accordance with 40 CFR 55.7(b)(4)(ii), Statoil proposes a NO X 

### + NMHC emission level

substitute of 11.03 g/kW-hr in lieu of the 9.8 g/kW-hr standard required by NSPS Subpart IIII.

Statoil has estimated the residual emissions resulting from the proposed emissions basis as

compared to the Tier 2 level and the results are presented in Table 18-2.

Statoil looks forward to working with the EPA during the permit review process to identify

emission reductions, if required, of a sufficient quantity to offset the estimated residual

emissions. All supporting calculations can be found in Attachment 4.

Statoil is waiting on final Developer main engine SCR cost data from the vendor and will supply

the data to EPA as soon as it is available. The cost analysis included in the application was

based on a preliminary cost estimate provided by Wartsila and was not considered final at the

time of submitting the application.

BACT Main Engine Replacement Cost Analysis ( Discoverer Americas )

Comment 21. The Discoverer Americas Main Engine Replacement discussion on pages

5-23 and 5-24 estimates 100 days to replace all of the main engines. However, the

discussion indicates that normal operation is using three engines with five on standby

and replacement costs are based on eight main generator engines. In the identification of

emissions units, the Discoverer Americas has only six main engines listed. Please clarify

if the estimated 100 days needed to replace all of the main engines is for six or eight

engines and provide an adjusted cost analysis and/or analysis summary to reconcile the

table in Appendix D with the text in Section 5.

Statoil confirms the Discoverer Americas has six main engines. The BACT section text

describing eight main engines on pages 5-23 and 5-24 is an error. However, the conservative

estimate of 100 days to replace the six main engines is accurate. The cost effectiveness for

replacing one main engine with a Tier 2 engine remains at approximately $85,851/ton NO X 

### removed. Statoil does not believe that engine replacement is cost effective for the main

generator engines on the Discoverer Americas

Part 71 Forms

Comment 22. Although the text in Sections 3.2.8.3 and 3.3.9.3 correctly describes drilling

mud as an insignificant activity (e.g., potential emissions of regulated air pollutants are

less than two tons per year and hazardous air pollutants are less than 1000 pounds per

year), the part 71 forms included in Appendix A do not list mud degassing as an

insignificant activity for either operating scenario. Please submit the corrected Part 71

forms classifying mud degassing as an insignificant activity.

Revised Part 71 forms for the Developer are included as Attachment 3 of this response letter.

Statoil has included mud degassing as an insignificant activity in the Part 71 forms. ENVIRON

will provided EPA with updated Part 71 forms for the Discoverer Americas as soon as we

receive the remaining supporting documentation and update emission estimates.

We hope the responses provided herein as well as the supporting documentation attached has

addressed your questions and request for additional information. As noted previously, we are

working closely with Statoil, vessel owners, and vendors to gather additional information to

address other items you have raised. We will provide additional information as soon as it is

made available and we have incorporated into the permit application sections as appropriate.

Consistent with the number of original appl ication submittals, please find attached 2 paper

copies and 8 electronic CD copies of the response. In addition, an electronic copy is being

Subject: Maersk Developer - Caterpillar Engine Question



### Hi Greg,

I am working with Maersk and Statoil to develop an air permit application for exploratory drilling in the eastern Gulf of

Mexico.

As part of the permit application, we need to revie w that the engines on the drilling vessels are cert ified to comply with

EPA’s emission standards. Maersk provided me with your contact information and I am hoping you can he lp me gather

some emission certification data for a Caterpillar engine on the Maersk Developer drill vessel. The e ngine I need some

backup information on is a CAT 3516B manufactured i n November 2006 (Serial Number: S2R00259). If it i s helpful, the

drill vessel was manufactured by Keppel Fels at the Keppel Fels, Singapore shipyard.

From previous experience, a Caterpillar dealer can look up engine performance information on the

http://tmiwebclassic.cat.com website. Would you be able to help me verify the emissions data and any EPA

certifications that the Caterpillar engine in quest ion many have? A print out or PDF of the informati on would be a great

help for preparing the permit application.

Thank you very much in advance for any help you can provide, and please do not hesitate to give me a c all if you have

any questions or concerns.

Thanks,

Kyle6

The emergency generator engine (EGEN) on theDiscoverer Americasis required to be certified to EPA Tier 2 emissionstandards per 40 CFR 60 Subpart IIII based on the engine size and manufacture year. However, the existing engine is not currently certified to EPA's Tier IIemission standards. Thus, Statoil is seeking exemption from NSPS emission standards as allowed in 40 CFR 55.7. The only compliance option Statoil hasis to replace the EGEN engine with a new EPA-certifiedengine, which is considered technically infeasible. In accordance with 55.7(b)(4)(iv), the followingcalculations estimate emission offsets based on the difference between the Tier 2 emission standards and the current emissions basis for the EGEN.Note, test data for the EGEN shows CO emissions less than the Tier 2 emission level (5.0 g/kW-hr) and the AP-42 PMemission factor for large engine isless than Tier 2 emission level (0.5 g/kW-hr). Therefore, Statoil assumed existing and Tier 2 certified CO andparticulate matter emissions for the EGENwere equivalent.
