# EXECUTIVE SUMMARY

This report identifies emission units and emissions to the atmosphere associated with the S hell Gulf of Mexico Inc. (Shell) exploration drilling program at Outer Continental Shelf (OCS) lease block s at the Burger Prospect in the Chukchi Sea

. This document has been prepared to assist the Bureau of Ocean Energy Management ( BOEM ) in the assessment and authorization of air emissions attributable to Shell’s exploration drilling operations

. Th is d ocument presents the following two emission inventories

.
1. For purposes of demonstrating applicability under the BOEM Air Quality Regulatory Program (AQRP) (30 CFR Part 550, Subpart C), Shell provides an AQRP emission inventory. As required by 30 CFR 550.218(a)(3), the inventory is estimated based on the projected emissions of the maximum rated capacity of the equipment on the proposed drilling unit under its physical and operational design

.
2. For purposes of demonstrating impacts under the National E nvironmental Policy Act (NEPA), Shell provides a NEPA emission inventory. This inventory provides an estimate of expected emissions in geographic areas of interest

. This document describes the types of activities and locations that would result in onsh ore and offshore air emissions associated with Shell’s exploration drilling program as described in the Shell Revised Outer Continental Shelf Lease Exploration Plan, Chukchi Sea, Alaska, Revision 2 ( EP Revision 2 )

. The emission inventories described her ein adopt a number of conservative assumptions that result in an overestimate of the actual onshore and offshore emissions associated with the EP Revision 2. Actual activities and locations may vary but are expected to contribute to lower increases in air emission impacts. In particular, the following conservative assumptions have been adopted:

• Annual emissions from the drilling units are based on continuous operation of engines , boilers , and incinerators for 24 hours per day (at 80 percent load for the engines; 100 percent load for boilers and incinerators ) for the entire 120

- day season (2,880 hours per

season ) , even though that is a significant ove restimate of their use.

• Annual emissions from certain engines , boilers , and incinerators on a number of support vessels are based on continuous operation 24 hours per day for the entire 120

- day season (2,880 hours per season) , even though that is a significant overestimate of their use.

• Annual emissions from emergency generator engines, lifeboat engines, rescue crafts , and seldom

- used engines on support vessels are based on an assumed 500 hours of operation in the season , even though that is a significant overestimate of their use.Shell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

– AQRP and NEPA Emission Inventories Page 8 of 93 

### • Annual emissions from the small oil spill response equipment are based on operation of engines 8 hours per day for the entire 120

- day season , even though they will only be used fo r training exercises ; this is a significant overestimate of the equipment’s use

.

• Annual emissions from drilling units do not account for the use of any existing emission control systems (e.g., selective catalytic reduction [SCR] , catalyzed diesel particulate filter s [CDPF] ) when they are currently installed and will be used to reduce emissions ( Table 6 identifies the units currently installed with emission control systems ).

• Annual emissions from the support vessels do not account for t he use of SCR emission control systems when they are currently installed and will be used to reduce emissions ( Table 6 identifies the vessels and units currently installed with emission control systems ).

• Annual sulfur dioxi de ( SO 2 

### ) emissions are calculated assuming higher, conservative 100 parts per million ( ppm ) sulfur content , even though Shell will use U ltra L ow S ulfur D iesel ( ULSD ) or a fuel with equal or lower sulfur content (but that will be mixed with fuel blending with any residual non

- ULSD fuel that remains in the tanks prior to the drilling season).Shell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

# 1.0 DRILL ING UNITS AND SUPPORT VESSELS

This section identifies the drilling unit s Shell intends to use for exploration drilling and describes the vessel s that will support the drilling unit s. For more detailed information on the drilling unit s and the support vess els, please refer to section 13.0 of th e Chukchi Sea EP Revision 2

. 

## 1.1 Drill ing Units Shell plans to use two drilling units , the Motor Vessel ( M/V ) Noble Discoverer ( Discoverer ) and the Mobile Offshore Drilling Unit (MODU) Transocean Polar Pioneer ( Polar Pioneer ) , to continue its exploration drilling program. Shell presents the known or expected emission units at the time of filing this EP Revision 2 , but i t is important to note that one or more of the engines on board the drilling units may change as maintenance or equipment needs demands.



## 1.1.1 Discoverer
The Discoverer is a drillship equipped with a propulsion engine, electrically powered thrusters, engine

- driven electrical generators for the drilling motors, and other self

- powered equipment. The self

- powered equipment includes hydraulic pumps, cranes, boilers, an incinerator, and other (mostly emergency

- related) small sources. There will be no flares and no hydrocarbon

venting sources except for minor amounts associated with the drill cuttings. Table 1 lists the emission unit s associated with the Discoverer

## 1.1.1.1 Generat or Engines Power generation for drilling e xploration well s involves drilling, casing, cementing, and logging. Each activity requires a different level of electrical power consumption. The high est power consumption is expected to occur when the drilling unit is used to excavate and drill the mud line cellar (MLC ). (As noted in the EP Revision 2 and discussed in Section 1.2.7 below, some or all of the MLCs may be constructed using a separate MLC Remotely Operated Vehicle [ ROV ] s ystem .) Casing, cementing, and logging require minimal power , and generator engine demand is reduced during these periods

. Six Caterpillar 3512C generator sets comprise the Generat or Engine s emission unit group as described in Table 1 . This system provides the primary power for the drilling as well as the ship utilities, and the number of operating units and load levels vary throughout the drilling process. Each of the six generators is fitted with SCR and CDPF control devices t hat reduce the nitrogen oxide (NO X 

### ), particulate matter (PM), carbon monoxide (CO), and volatile organic compound (VOC) emissions.
Although at least several of the main generators operat e continuously while the Discoverer is

on site, other diesel engines (described below) are used only occasionally for specialized and intermittent tasks.



## 1.1.1.2 Propulsion
The Discoverer is self

- propelled with a single STX

- MAN Model 6S42MC7, International Maritime Organization (IMO) Tier II, 6,480 kW engine. This engine will be used to propel the Discoverer to the drill site, and to assist in holding position while the mooring is connected and tensioned. In extreme high winds, the engine may be used to assist the anchors in holding the vessel in position.



## 1.1.1.3 Hydraulic Power Units The hydraulic power units (HPU) consist of two approximately 200 kW engines and are used primarily for assisting in the rotation of the up to 30

- foot

- dia meter bit for drilling the MLCs

. The se engines may also be occasionally used for other unspecified tasks.



## 1.1.1.4 Cranes
The Discoverer has two 450 kW engines that power two cranes used intermittently to move materials around the deck and to load /off

- load supplies . The operating levels of the crane engines are highly variable depending on the weight and type of material being moved. The duty cycle consists of lifting a load, swinging the load, lowering the load, and idling while the load is disconnected, then swi nging back to the position of a new load and idling as it isShell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

– AQRP and NEPA Emission Inventories Page 11 of 93 

### connected. The only activity that consumes high power is the load lifting; the remainder of the cycle is at low power.



## 1.1.1.5 Cementing Units
There are two 250 kW cementing pumps on the Discoverer . These cementing units are used intermittently to force liquid slurry of cement and additives down the casing and into the annular space between the casi ng and the wall of the borehole . The cement ing units are also used intermittently as high

- pressure pumps for hydrostatically testing various types of well equipment and drilling components such as the wellhead connections and the blowout preventer.



## 1.1.1.6 Logging Unit , Compressor, and Sidewall Core Tool Engines The logging unit, compressor, and side wall core tool engines are portable equipment associated with the planned acquisition of a standardized subsurface evaluation program at each drill site

. This portable equipment will provide the energy to run the electric wireline logging (EWL ) program, t he Zero

- offset Vertical Seismic Profil e (ZVSP ) program , and the sidewall coring program at each drill site. The compressor required to conduct the ZVSP program will be used infrequently to collect localized geophysical data at various depths in each w ell.



## 1.1.1.7 Emergency Generator
The Discoverer has a Caterpillar 3412 engine driving a 507 kW emergency generator to power basic drillship utilities if the primary power system is inoperable. It is capable of powering only domestic and worker safety devices and not the drilling equipment. There are no planned uses of the emergency generator except weekly exercising, which involves operation for approxim ately 20 minutes.



## 1.1.1.8 Lifeboats
The Discoverer has four lifeboats , each equipped with a Sabb 29.5 horsepower ( hp ) engine. Vendor data are provided in Attachment F . The only planned use of the lifeboats is monthly exercising to comply with Coast Guard requirements.



## 1.1.1.9 Boilers
The Discoverer has two diesel

- fired boilers to provid e domestic and workspace heating. Typically, only one boiler is operating at a time.



## 1.1.1.10 Waste Incinerator
Domestic and other non

- hazardous materials are to be incinerated as needed. This man

- camp
style incinerator is a two

- stage, batch

- charged unit capable of burning 276 lb /hr of solid trash.Shell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

– AQRP and NEPA Emission Inventories Page 12 of 93 

## 1.1.2 Polar Pioneer
The Polar Pioneer is a semi

- submersible MODU that is capable of operating in harsh environments and variable water depths. The Polar Pioneer can slowly move using the eight

on board electric thrusters; however , it is customary for the Polar Pioneer to be towed on location. The Polar Pioneer is kept on a d rilling location with a conventional mooring system. The Polar Pioneer contains main generator engines, boilers, a compressor engine, and an incinerator. Table 2 lists the emission units associated with the Polar Pioneer

## 1.1.2.1 Generat or Engines Five Bergen KVG

- 18 diesel engines, rated at 3,890 hp each, driv e five 2,750 kW AC generator s , which comprise the Generat or Engines emission unit group described in Table 2

. Because cementing equipment and cranes are electrified, the Polar Pioneer generators provide the primary power for the drilling as well as the ship utilities, and the number of units and load levels vary throughout the drilling proce ss. Although at least several of the main generators operate continuously while the Polar Pioneer is

on site, other diesel engines (described below) are used only occasionally for specialized and intermittent tasks.



## 1.1.2.2 Hydraulic Power Units
The HPUs consist of two approximately 2 5 0 hp engines and are used primarily for assisting in the rotation of the up to 30

- foot diameter bit for drilling the MLCs. These engines may also be used occasionally for other unspecified tasks.



## 1.1.2.3 Logging U nit , Compressor, and Sidewall Core Tool Engines The logging unit, compressor, and sidewall core tool engines are portable equipment associated with the planned acquisition of a standardized subsurface evaluation program at each drill site

.Shell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

– AQRP and NEPA Emission Inventories Page 13 of 93 

### This portable e quipment will provide the energy to run the EWL program, the ZVSP program , and the sidewall coring program at each drill site. The compressor required to conduct the ZVSP program will be used infrequently to collect localized geophysical data at various depths in each well.



## 1.1.2.4 Emergency Generator Engine
The Polar Pioneer has a TEJOS MTU 12

- 396 1,120 kW emergency generator to power basic drill unit utilities if the primary power system is inoperable. It is capable of powering only domestic and worker safety devices and not the drilling equipment. There are no planned uses of the emergency generator except weekly exercising, which involves operation for approximately 20 minutes at loads up to capacity.



## 1.1.2.5 Small Emergency Engines
The Polar Pioneer has a Rescue Boat equipped with a Harding 212 hp engine, four lifeboats each equipped with a Vetus 52 hp engine, a forward fast rescue craft with a Bukh 144 hp engine , and an A ft fast rescue craft with a Volvo 147 kW engine. The only planned use of the boats is monthly exercising to comply with Coast Guard requirements. In addition, an emergency start compressor engine with a Hatz 11 hp engine is on board the Polar Pioneer

. 

## 1.1.2.6 Boilers
The Polar Pioneer has two diesel

- fired boilers to provide domestic and workspace heating.



## 1.1.2.7 Waste Incinerator
Domestic and other non

- hazardous materials are to be incinerated as needed. This incinerator is a multi

- chamber unit capable of burning 100 kilograms per hour ( kg/hr ) of solid trash. Its incine ration capacity is limited to 500 kilocalorie s per hour ( kcal/hr ) (580 kW) of heat.


## 1.2 Support Vessels
The drilling unit s will be supported by i ce management vessels, anchor handlers, science vessels, support tugs, offshore supply vessels (OSVs), oil spill response vessels (OSRV s ) , tankers , and other vessels as described in the following sections

. 

## 1.2.1 Ice Management and Anchor Handling Vessels The ice management and anchor handling vessels ar e expected to consist of five contracted ships: two primary ice management vessels and three anchor handling vessels

. An anchor handling vessel will provide close support to each drilling unit or work to preset anchors at another drill site, while other primary ice management vessels will normally work several miles upwind of each drilling unit and may monitor the leading edge of any ice floe of possible concern, far upwind up to 30 n autical mi les from a drilling unit as described under Appendix G of the EP Revision 2 . These activities are necessary for managing ice at distances that provideShell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

– AQRP and NEPA Emission Inventories Page 14 of 93 

### adequate response time for drilling units to get off a well and anchor in case of encroaching ice that cannot be managed. These response times may vary depend ing on the drilling stage of the well hole

.
M anag ing ice involves deflecting or , in extreme cases , fragmenting ice floes that could impact the drilling unit when it is drilling. Removal of ice buildup on the upstream side of the drilling unit by “bow wash ing” may also occur . Bow washing involves backing the anchor handling vessel close to the drilling unit , and pushing the ice to one side or the ot her with its propeller wash , thereby clearing the ice.



## 1.2.2 Science Vessels

Two s cience vessels are responsible for monitoring drill discharges and other science

- related tasks. The vessels will sample drilling plume effluent during certain phases of the well drilling. Section 13a of the EP Revision 2 provides a description of drill d ischarge monitoring conducted by the science vessels. These vessels may also serve to conduct other tasks when not required to conduct discharge monitoring.



## 1.2.3 Support Tugs Tug boats will provide support to each of the drilling units. Two tugs will be used to deliver the Polar Pioneer to the drilling location and will remain on location in standby mode during drilling operations in case the Polar Pioneer must leave location quickly. In addition, another single tug will escort the Discoverer to the drill sit e , assist during mooring , and depart when no longer required

. For m ost of the drilling season, the tugs located onsite will be anchored or will be operate d at low speed.



## 1.2.4 Offshore Supply Vessels
Three OSVs will shuttle equipment and supplies between the drilling units and shore base locations that are out of the Program Area. For example, an OSV will transit to the Discoverer , and then p osition itself in dynamic positioning (DP) mode beside the drillin g unit for a day or longer for material or personnel transfer. At any one time, at most only one OSV is expected to be at e a ch drill site location off

- loading supplies.



## 1.2.5 Oil Spill Response Vessels
The OSR Vs at the Burger Prospect will include a main OSR V equipped with three 34

- foot work boats, and an oil spill response ( OSR ) tug/barge. These OSRVs will be used in the unplanned and unlikely event of an oil discharge to the water. During the drilling season, these vessels will primarily be used during refueling operations to protect against possible spills and will be located near the refueling Arctic oil storage tanker (OST)

. The se vessels will be available to both the Discoverer and the Polar Pione er

.Shell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

– AQRP and NEPA Emission Inventories Page 1 5 of 93 

### The work boa ts will remain on the deck of the OSR V and be deployed in the water for training, drills, and response events. Two work boats will be used to tow containment booms, while a third will be used as a backup, for crew changes, and for re

- fueling. OSR Vs will have on

- water drills at a maximum frequency of once per day

. 

## 1.2.6 Arctic Oil Storage Tanker
An Arctic OST will reside near the drilling units , and is expected to be staged at the Burger Prospect for the purpose of refueling all the vessels. In the unlikely event of a well

- control incident, it will also serve as a receiver of any oil skimmed by the OSR Vs . The tanker will be anchored for most of the drilling season , and refueling is expec ted to involve the other vessel moving to the tanker, with one or more vessels providing booming support during fuel transfers. An onboard incinerator may exist to burn solid waste.

A second OST will be inside the Program Area (i.e., Leas e Sale 193 Area) during exploration drilling but not within the 25

- mile radius

. Therefore, no emission estimates are provided for the second tanker in the AQRP or NEPA emission inventories

. The emissions associated with this second OST are comparable to the Arctic OST. In the event of an extended well

- control incident,
t he second OST will transit to the Burger Prospect to provide increased storage capacity for any collected oil.



## 1.2.7 MLC ROV System Vessel

A s described in the EP Revision 2, a ves sel capable of operating i n DP may be used to provide equipment to excavate MLC s at the Burger Prospect independently of the main drilling units. The MLC ROV s ystem equipment on th is vessel includes a dedicated engine to drive specialized underwater gear on or near the sea floor

. Section 2d of the EP Revision 2 provides a description of the MLC ROV s ystem and the anticipated use of the MLC ROV s ystem vessel

. 

## 1.2.8 Candidate Vessels
Each of the above

- listed support vessels may be contracted on a year

- to

# 2.0 OFF SHORE AIR EMISSI ONS

S ection 2.1 of this chapter describes the activity of the vessels and the emission units on them. S ection 2.2 identifies emission factors for each pollutant and emission unit. Together, the activity level and emission factors enable the calculation of short

- term and annual emissions. Section 2.3 of this chapter presents the emission s as appropriate for the AQRP emission inventory that is estimated according to 30 CFR Part 550 Subpart C , while section 2.4 presents emissions to support the NEPA emission inventory

. Air pollutants addressed here are NO X 

### , CO, particulate matter (PM 10 

### and PM 2.5 

### ), VOC, SO 2 

### , lead (Pb) , and greenhouse gases (GHG)

. Short

- term emissions are expressed as pounds of pollutant per hour (lb/hr). Long

- term emissions are presented as tons of pollutant per year . In effect, the long

- term emissions represent annual emissions over a maximum 120

- day drill season , and the terms long

- term, seasonal, and annual emissions are used interchangeably

. 

## 2.1 Vessel and Emission Unit Activity
Calculated s hort

- term emissions are based on engine nameplate ratings, modified by limitations established from a combination of safety policies and good engine care policies. In practice,

m aximum continuous power ratings of marine engines are typically 10 to 20 percent below

name plate power ratings. Such good engine operating practices extend equipment life. 1 

### In these calculations, the maximum operating rate for each engine is assumed to be 80 percent of the name plate rating in both the AQRP and NEPA inventories. In addition, the 80 percent short

- term maximum load was used along with the engine or engine group aggregate rating to determine the maximum aggregate rating. All boilers and incinerators are assumed to have a maximum load of 100 percent for both the AQRP and NEPA inventories.

Annual emissions from the drilling units are based on continuous opera tion of engines (at 80 percent load) for the entire 120

- day season

. To calculate annual emissions from support vessels , Shell has committed to annual fuel restriction s on the support vessels that are based on 2012 operational data , information supplied by the vessel owners or operators , or anticipated seasonal use

. T he proposed fuel restriction s apply to main generation an d propulsion equipment o n the support vessels. The proposed annual fuel restriction s for the support vessels presented in Table 5 are applied to both the AQRP and NEPA emission inventories. Limited fuel combusted by support vessels outside of the 25

- mile radius of the drilling units is expected to result in emissions that are well dispersed

. These fuel restrictions result in an emission

1 Documentation of this practice is further explained in the January 11, 2012 , letter from Susan Childs to the U.S. Environmental Protection Agency ’s ( EPA’s ) Natasha Greaves (included under Attachment E). This practice was applied during the actual 2012 source testing r equired under the EPA air permit and was described under the Discoverer Drillship Test Protocol submitted to EPA’s Natasha Greaves on February 22, 2012. EPA demonstrated concurrence with the 80 percent assumption by issuing permits and consent orders based on applications that included emission inventories and modeling performed using the 80 percent maximum power limit. The permits included fuel restrictions and emission limits that were calculated based on the 80 percent assumption.Shell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

### reduction of 4 4 to 90 percent, depending on the vessel (see Attachment D, Table D

- 13 for additional details)

. For similar vessels, a combined fuel restriction is proposed for similar vessels within the group. This applies to the Ice Management group, consisting of the Fennica and Nordica , and the OSV

- type, consisting of the Harvey Gulf Tiger

- class vessels, the Sisuaq and Supporter

## 2.2 Emission Factors

NO X 

### , CO, PM, VOC, and Pb emissions are calculated based on an activity level (discussed in S ection 2.1 ) and an “emission factor” that is expressed as a mass of emissions for a given activity level. The emission factors were selected based on a hie r ar chy of available data. First, when availab le , emission tests of a specific engine or group of engines (referred to as a source test)

were used to determine emission factors. If source test data were not available, emission factors provided by engine vendors were used

. If neither source tests nor vendor data were available, emission factors were selected from t he EPA’s compilation of emission factors ( commonly referred to as AP

- 42 )

. There are two exceptions to this hierarchy. Firs t, the NO X 

### emission factor for the Discoverer propulsion engine is based on IMO Annex VI, Tier 2. Second, SO 2 

### emissions from diesel combustion are calculated based on sulfur content of the fuel , assuming 100 parts per million byShell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

– AQRP and NEPA Emission Inventories Page 21 of 93 

### volume ( ppmv ) to account for any fuel blending that may occur when ULSD or lower sulfur content fuels are added during the drilling season to the residual fuels in the tanks that may exist prior to the start of the exploration season

. In the AQRP and NEPA emission inve ntories, Shell has elected to apply emission factors with pollutant reductions to account for some of the existing control technologies that are currently installed on drilling units and support vessels. Emission factors with emission controls applied

are only used where reductions are necessary to demonstrate compliance with these programs. For example, the Discoverer , Fennica , Nordica , Aiviq , Tor Viking , and Nanuq vessels are currently equipped with CDPF and OxyCat emission controls on certain equipment to reduce PM, CO, and VOC emissions

. However, these emission reduction technologies are only applied to emission factors in the NEPA emission inventories. CDPF and OxyCat emission reduction technologies are not applied under the AQRP emission inventory because these reductions are not necessary for demonstrating compliance under the AQRP.

The Discoverer primary generators have been retrofitted with CleanAIR’s E

- PODTM system to actively reduce NO X 

### , using SCR technology

. NO X 

### reacts selectively with ammon ia across a catalyst and is reduced to nitrogen and water. The E

- PODTM combines SCR technology with oxidation catalysts or particulate filters that reduce PM, CO , and hydrocarbon emissions as well. The Aiviq’s propulsion and generator engines also contain an E

- PODTM system. The Fennica, Nordica , and Tor Viking main engines have been retrofitted with a different SCR and oxidation catalyst s ystem for the control of NO X 

### , PM, CO , and VOC emissions. The Nanuq’s propulsion and generator engines have been retrofitted with CleanAIR’s PERMITTM filter system for the control of PM, CO , and hydrocarbons. Table 6 summarizes the emission units with emission controls.
As shown in Table 6, Shell has installed SCR pollutant control te chnologies on certain equipment on the drilling units and support vessels. However, no NO X 

### pollutant reductions for the SCR emission control technologies currently installed are applied to the emission factors used in the AQRP and NEPA emission inventori es. The SCR emission reductions are not necessary to demonstrate compliance under the AQRP or NEPA.

### As stated, the AQRP emission inventory assumes that 100 ppmv sulfur content fuel is combusted to account for any fuel blending that may occur when ULSD or another fuel with lower sulfur content is added to any residual fuel that may exist in a tank prior t o the start of the exploration season. But, the AQRP emission inventory does not apply any of the existing emission control systems listed in Table 6 because they are not required to demonstrate that the project emissions are below the BOEM exemption thresholds. The NEPA emission inventories account for the use of reduced sulfur fuel on all drilling units and vessels, and also acknowledge the reduction of PM from existing emission control devices on the Fennica, Nordica, Aiviq, Tor Viking , and Nanuq because these are the only emission controls required to demonstrate compliance u nder NEPA. Even though emissions are not calculated with all identified emission reductions, Shell will attempt to utilize those controls not applied in the AQRP and NEPA emission inventories during exploration drilling.



## 2.2.1 Source Test Data Over several year s , Shell had numerous emission units source

- tested on board the Discoverer and a number of the candidate support vessels. In 2012, prior to exploration drilling, over 800 various source tests were conducted, as required by the now terminated EPA Discover er Prevention of Significant Deterioration Permit to Construct (R10OCS/PSD

- AK

- 09

- 01) and the Kulluk Title V P ermit (R10OCS030000). Shell has elected to use these source test results as applicable for a number of the emission units.

In 2007, NO X 

### emissions from the Fennica were measured. These source tests were completed prior to the installation of the SCR control system on the main propulsion engines. In both the AQRP and NEPA emission inventories, Shell use s the measured uncontrolled NO X 

### emis sions from the 2007 tests for both the Fennica and the Nordica , a sister ship to the Fennica

. Also in 2007, as required by the EPA Kulluk Air Quality Control Minor Permit (R10OCS

- AK

- 07

- 01) , NO X 

### emissions were measured from t wo engines on the Tor Viking

. These source test s were conducted with and without the SCR operating

. In both the AQRP and NEPA emission inventories, Shell use s the measured uncontrolled NO X 

### emissions from the 2007 tests for the Tor Viking

. Finally, Transocean had the Polar Pioneer main engine #3 source
- tested in 2014 to determine emission factors for NO X 

### and CO. 2 

### These emission factors are representative of the Polar Pioneer G enerator E ngines group , as described in Table 2 , and are used in both the AQRP and NEPA inventories.

2 PM filterable was measured during the test, but the condensable particulate portion was not measured during the test. Consequently, the PM source test measurements were not used in these emission calculations.Shell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

– AQRP and NEPA Emission Inventories Page 23 of 93 

### All the source tests were completed at various load s

. T o calculate emissions for the drilling unit s and support vessels, Shell average d measured emission factors over all the loads over similar engines . F or example, the source test results for both Di scoverer HPU engines, at two different loads, were averaged , and a single factor was determined to represent emissions from the Discoverer HPU engines group

. 3



### Table 7 lists the emission unit groupings that use source test emission factors in the applicable emission inventory . Copies of the source test summary tables can be found in Attachment F , along with applicable portions of the reference s provided in section 4.0 of this report.

3 Because generators typically convert over 90 percent o f the energy coming from the engine into electricity, 2012 source test emission factors for generators provided in pounds per kilowatt electrical hour (lb/kWe

- hr) were converted to lb/kW

- hr by dividing the average group emission factor by 95 percent. This produced a conservative engine emission factor.Shell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

a The c ontrolled emission factor was applied for the AQRP emission inventory because the uncontrolled vendor data PM emission factor was less than the controlled source test emission factor. See Section 2.4 for more information

.


## 2.2.2 Vendor Data
In those cases wh e re source test data were unavailable, v endor emissions data were selected, if available

. In other cases, source test data were available for a controlled engine but an
uncontro lled emission factor was needed for the emission inventory

.
Because t he Discoverer Caterpillar D399 g enerat or engine s were replaced in 2013 with Caterpillar 3512C en gines, the 2012 source test data results for these engines a re no longer applicable. Vendor data for the Caterpillar 3512C engines w ere received from Louisiana CAT (Attachment F ) with Rated S peed “ Nominal Data” for NO X 

### , CO, hydrocarbon ( HC ) , and p articulate matter in lb/hr . These emissions represent uncontrolled engine emissions and were converted to g rams per k ilowatt hour (g/kW

- hr ) for use in the emission inventories

. Even though controls are present and will be used throughout the season on th e generators, the Discoverer generation emission factors do not apply any emission reduction.

Because Discoverer cranes were replaced in 2013, the 2012 source test data results are no longer applicable. Liebherr Machines Bulle SA, the manufacture r of the cranes, provided an “Exhaust Emission Confirmation” for the installed engine D9508 A7.

## 2.2.4 Sulfur Dioxide Emissions Shell has committed to purchase and use ULSD fuel or fuel with lower sulfur content during the drilling season. A material safety data sheet (MSDS) for the fuel type Shell intends to use lists ULSD with a sulfur content of 15 ppm maximum (Attachment F ). However, some of theShell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

.
Attachment F also provides a copy of the email from Royal Harris dated April 20, 2011 , providing details on the diesel produced by Tesoro Nikiski. The email states the specific gravity of ULSD as 0.8398 using “ASTM D4052

In addition, the email s upports a net diesel heat content of 131,180 Btu/gallon that was utilized in the AQRP and NEPA emission inventories for the calculation of emissions.



## 2.2.5 Greenhouse Gas Emissions Greenhouse gases are not a regulated pollutant by BOEM but are relevant to BOEM’s NEPA analysis and are presented in Shell’s Environmental Impact Analysis ( EIA ) addressing the EP Revision 2 . 40 CFR Part 98, Subpart C, Table C

## 2.2.6 Lead Emissions
Because lead emission factors for diesel

- fired internal combustion engines are not provided in AP

- 42 Chapter 3, Sections 3.3 and 3.4, EPA’s Locating and Estimating (L&E) Air Emissions from Lead Sources and Lead Compounds report was used. Section 5.2.2 of this report provides an emission factor o f 2.9E

- 5 lb/MMBtu for distillate oil

- fired gas turbines. These emission factors should be representative of any distillate

## 2.3 AQRP Offshore Emission s Summary The AQRP emission inventory addresses the emissions from the “facility,” which is defined at 30 CFR 550.302 to mean : any installation or dev ice permanently or temporarily attached to the seabed which is used for exploration, development, and production activities for oil, gas, or sulphur and which emits or has the potential to emit any air pollutant from one or more sources. All equipment dir ectlyShell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

– AQRP and NEPA Emission Inventories Page 31 of 93 

### associated with the installation or device shall be considered part of a single facility if the equipment is dependent on, or affects the processes of, the installation or device.
In addition to presenting emissions for the drill ing unit s, Shell also present s aggregate emissions for the facility that include the support vessels operating within 25 miles of the drill ing unit s. The AQRP emission inventory was developed for sources without consideration of emission control technologies , but does include good engine operating practices (i.e., engine power restrictions for ensuring extended equipment life) and proposed seasonal fuel restriction s for the support vessels. Note that the proposed fuel restriction s apply only to main generation and propulsion equipment of some of the support vessels.
The AQRP emissions are based on the conservative assumption that all engines on the Discoverer and the Polar Pioneer operate every hour of the season at 80 percent load. The boilers and incinerators associated with the drilling unit s are assumed to operate at rated capacity every hour of the season.

Emission s from the Discoverer Support T ug ( Lauren Foss ) generator and thruster engines are based on 21 days per season o f operation.
Emissions from all emergency generator engines, lifeboat engines, rescue crafts , and seldom

used engines on board the support vessels are based on a conservative assumption of 500 hours of operation per season

. Emissions from the small OSR equipment used during training exercises are based on operation of eight hours per day and 120 days of operation per season.

Emission s from propulsion and generator engin es on board the support vessels are based on seasonal fuel restrictions except for the following engines:

– Generator Engines , Thruster Engine, Emergency Engine, and MLC ROV System Engine
These engines and the remaining units on board the drilling units and support vessels are estimated based on 24 hours per day, 120 days per season , for a total of 2,880 hours p er season with exception of “Emergency” and “OSR Equipment” engines

## 2.4 NEPA Offshore Emission s Summary
The NEPA emission inventory is similar to the AQRP emission inventory except that PM emission reductions have been applied where PM emission control equipment currently exists on a support vessel

. Although the NEPA analysis presented in Attachment B to Appendix C (t he EI A) also addresses emissions from the on shore facilities , vehicles , and aircraft trips , the

on shore emissions are addressed in Section 3 .0 of this report rather than in this section . Both the AQRP and NEPA inventories are limited to a 120

- day maximum drilling season.
Although emission controls will be in place (and operational) on many of the largest engines, Shell chooses to demonstrate that exploration operations will not exceed BOEM impact criteria even if the benefits of NO X 

### or CO emission controls are not taken into consideration . The sole exception to this is the Aiviq propulsion engines; because the uncontrolled vendor data PM emission factor was less than the controlled source test emission factor, the controlled emissio n factor is used in both the AQRP and NEPA emission inventorie s. The support vessels that contain PM emission controls are identified in Table 17

### The Fennica and Nordica Harbour Generators are assumed not to operate during drilling season because this equipment is not required while away at sea.
Table 18 presents the NEPA emission i nventory offshore projected peak hourly emissions by group for the Discoverer , the Polar Pioneer , a nd their support vessels. Table 19 presents the offshore project e d annual NEPA emission inventory emissions by group

. During exploration activity, the support vessels will virtually always operate within 25 miles of one of the two drilling units. The obvious exception to this is when OSVs are in transit to Dutch Harbor or other resupply ports. It is also possible that o n occasion the ice management vessels or other support vessels would travel farther than 25 miles. This activity is accounted for in the proposed annual fuel restriction s and, therefore, the emissions estimates.
Ships traveling farther than 25 miles fro m the drilling units would disperse the emissions to a greater extent than when they are closer to the drilling units. Because the dispersion modeling conducted in support of the NEPA inventory concentrates all emissions within 25 miles of theShell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

### drilling un its, it results in predictions that are higher than those expected if some vessels venture outside the 25 mile radius. Consequently, additional modeling of that scenario is not warranted.Shell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

# 3.0 ON SHORE AIR EMISSIONS

Land

- based emissions include those from personnel and supply transport ed to and from the drill site, and any housing emissions dedicated to the project. The on

- land activities associated with the exploration activities are likely to include support facilities in Barrow

. The se facilities in Barrow include a man

- camp, storage facilities, and an aircraft hangar, requiring heat and power. Other possible minor support activities may occur in Wainwright at existing leased facilities. Transport ation of personnel and materials to and from the airport would be by automobiles, vans, or pickup trucks, fueled with diesel. Transport to and from the vessels to shore will be by up to three helicopters, stationed in Barrow. Additional fixe d wing aircraft will be used for crew transport. Communications may be through existing communicatio ns center networks or leases from existing facilities.


## 3.1 Aircraft Activity
Emissions from aircrafts are estimated using the Federal Aviation Administration’s (FAA) Emissions and Dispersion Modeling System (EDMS). EDMS is a combined emissions and dispersio n model for assessing air quality at civilian airports and military air bases. The model was developed by the FAA in cooperation with the United States Air Force (USAF). The model is used to produce an inventory of emissions generated by sources on and a round the airport or air base, and to calculate pollutant concentrations in these environments.

As described in Section 13 of the E P Revision 2 , Shell intends to operate the following aircrafts with the exploration drilling program:

• ( 3 ) crew change helicopters

• (1) search and rescue (SAR) helicopter

• (1) fixed

- wing aircraft for crew transport , with an option for a helicopter

• (1) fixed

- wing aircraft for ice reconnaissance

• (1) fixed

- wing aircraft for Protected Species Observer ( PSO ) flights
As described in Table 13.a

- 3 of the E P Revision 2 , Table 20 lists the purpose, proposed a ircraft types, and trip frequenc ies used to determine the air emissions.Shell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

- wing aircraft for crew transport

. The change in emissions from th e alternate aircraft is minimal. 

### The EDMS estimates emissions for a landing / take

- off (LTO) cycle. The aircraft that was closest in size and engine capacity was used to estimate emissions from one LTO cycle. The emissions were then multiplied by the total number of LTOs for the season. Total emissions from these aircraft along with an analysis of the EDMS LTO emission estimates for each scenario can be found in Attachment C 2 . The ED MS output file can be found in the Appendix K folder of the flash drive.


## 3.2 Hangar /Storage Building Activity

A hangar /storage building located in Barrow at the airport is expected to be heated by a small 5 MMBtu/hr, natural

- gas
- fired boiler , and operational 12 hours per day for 168 days per season

. The make and model of this boiler is currently unknown ; therefore , emission factors from AP

42’s Chapter 1 for external combustion sources, Section 1.4 for natural gas combustion were selected. Table 21 list s t hese emission factors , and total e missions from this source can be found in Attachment C 1

## 3.3 Camp Activity 3.3.1 Existing 75

- person NARL Camp Activity
The current 75

- person camp located near the Naval Arctic Research Laboratory ( NARL ) is powered by two John Deere PowerTech 13.5L, 448 kW, diesel generators. One generator servesShell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

– AQRP and NEPA Emission Inventories Page 46 of 93 

### as the primary generator and the other is a backup generator. Similar to the vessel internal combustion engines, it is assumed that “good engine operating practices” will be used to extend the life o f the generators. Therefore, the maximum load is assumed to be 80 percent for emission calculations. In addition, it is assumed that the backup generator will only operate 1 hour per week for routine maintenance checks.
The John Deere generators are EP A

- certified Tier 3 ; therefore, 40 CFR 89.112 Nonroad, Tier 3 standards have been selected to calculate emissions. Because there is no Tier 3 VOC emission factor, the Tier 1 standard was (conservatively) selected. Finally, SO 2 

### emissions were calculated assuming 100 ppm sulfur content (see Section 2.2.4 ) , and lead emissions were calculated using EPA’s Locating and Estimating Air Emissions from Lead Sources and Le ad Compounds report (see Section 2.2.6 ). Table 22 list s the emission factors for these engines , and total emissions can be found in Attachment C 1

- person Ukpeaġvik Iñupiat Corporation (UIC) modular construction camp; th is camp is now at the UIC storage location in Barrow but would be relocated by UIC to the existing UIC pad near the NARL camp

. This is a separate location from the existing UIC camp near NARL described in Section 3.3.1 . This 40

- person camp will be tied to the grid for power ; there are no other emission units onsite.Shell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

– AQRP and NEPA Emission Inventories Page 48 of 93 

## 3.4 Vehicle Activity Vehicle emissions were estimated using EPA’s Office of Transportation and Air Quality (OTAQ) M o tor Vehicle Emission Simulator (MOVES). Vehicle emissions are e stimated to occur during the transportation of personnel and materials to and from the airport using diesel

- fueled automobiles, vans, or pickup trucks. The MOVES model was r u n to estimate emissions from a passenger truck, model year 2012 , in the Alaska N orth Slope Borough. The MOVES program provides hourly emission estimates for each weekday and weekend day for every month. It was assumed that the emissions for this project will occur during July, August, September , and October. The seasonal e missions were then conservatively estimated to occur 12 hours per day for the total 12 3 day s (July 1 st



### – O ctober 31 st 

### )

. Hourly emissions were estimated by selecting the maximum hourly emissions for each pollutant for the same timeframe

. The emission value s can be found in Attachment C 3 , and the MOVES output file can be found in the Appendix K folder of the flash drive.Shell Chukchi Sea E xploration P lan, Revision 2 February 6 , 2015 Appendix K

## Shell Exploration & Production

Natasha Greaves OCS/PSD Air Quality Permits U.S. EPA - Region 10, AWT-107 1200 Sixth Avenue, Suite 900 Seattle, Washington, 98101

January 11, 2012

Re: Frontier Discoverer Source Tests Shell OCS Exploration Program
On September 19, 2011, EPA issued Shell Gulf of Mexico Inc. (Shell) Prevention of Significant Deterioration Permits to Construct for the Noble Discoverer drill ship operations in the Chukchi and Beaufort seas. The PSD permits require measurement of emissions from most of the emission units on the Discoverer and on the Discoverer’s associated fleet via source testing.
The purpose of this letter is two-fold. First, we request EPA concurrence with Shell’s intent to measure at on-shore facilities emissions from certain engines not now on the Discoverer. Secondly, we request EPA concurrence that physical or contractu al limitations imposed on engine operating capacity can be considered when defining 100 percent load (and
, correspondingly, fractions of that 100 percent load). As explained below, we believe Shell’s approach meets the intent of the permit while ensuring a safer and equally realistic testing process.

On -shore testing
Shell intends to test the main generator engines, the port crane engine, the boilers, and the incinerator on the Discoverer because these emission units are permanently installed. However, none of the other engines that requir e testing are currently onboard the drill ship; in fact, most of the other engines are portable and routinely removed from the drill rig at the end of each drill

season. The PSD permits require Shell to test certain engines prior to the beginning of the drill season. Because of other construction activities that will be undertaken at the same time on the Discoverer, and the limited deck space available for those activities as well as source test equipment, testing certain engines at an on shore site will simply allow for a higher level of safety for testing, and personnel during testing. Shell would maintain that the physical location of the equipment during testing should not be an issue here, as the operating range necessary to be maintained to confirm accurate testing will need to be maintained whether the engine is physically located on the Discoverer at the time of testing or not.

## EPA Region10

January 11, 2012 Page 2

Shell therefore proposes to test the starboard crane engine, the Mud Line Cellar Hydraulic Power Unit engines, the Mud Line Cellar Air Compressor engines, the cementing engines and the C7 logging winch engine at an on-shore facility. It is likely that testing will take place at NC Machinery, south of Tukwila, Washington. Although engine-specific information will be included in test protocols, dynamometers or hydraulic flow restrictors are likely to be used to load the se engines to the operating rates required by the permits.
Definition of engine load
The Discoverer PSD permits require Shell to measure emissions from the engines powering the main generators, mud line cellar compressor engines, hydraulic pressure unit engines, crane engines, and cementing and logging engines at multiple loads. However, a number of the se engines power equipment that, for various reasons, preclud e operating, and as an extension testing, the engine to its full rated capacity. In some other cases, where the emissions units are owned by others, there are contractual restrictions on the maximum allowable engine operating loads.
In both cases, Shell proposes to redefine the maximum operating rate of the engine (100 percen t load) to reflect those restrictions. Partial load testing (e.g., 50% load or 80% load) would also be correspondingly adjusted relative to this redefined maximum load condition. Below please find explanations of why, and examples of how, this would work for the subject engines.

FD 1-6. Main Generators
Noble, the owner of the Discoverer, has established 800 kW as the maximum operating rate for the generators, and has installed an electrical distribution system with controls that limit the engine s’ operating rate accordingly. This operating rate is nearly 20 percent lower than the 988 kW nameplate rating on the engine. With this contractual and operational restriction in place, Shell submits that an engine operating rate that results in 800 kW output reflects the true 100 percent engine load to be encountered during our OCS drilling operations, and that the “100% load” source tests should take place at this restricted engine operating rate. Similarly, source tests at 75% and 50% load should be conducted at engine operating rates that generate 600 and 400 kW, respectively.

FD 14-15. Deck Cranes
Each of the deck cranes engines are rated at 365 HP. The PSD permit requires testing at 60-80% and 80-100% loads.
Crane engine testing is challenging, as the engine is only one part of the crane hoisting system. The maximum load on the system is defined by the boom capacity, which for the cranes on the Discoverer is much less than the hoisting capacity of the corresponding engine and winch. One hundred percent boom capacity for the cranes to be used on the Discoverer translates to about 310-320 HP of engine/winch capacity, which is below their nameplate capacity. Because the

## EPA Region10

January 11, 2012 Page 3
cranes cannot physically exceed the boom capacity, the engines are functionall y limited to a lower load than their name plate rating. There is a boom radius-load indicator and alarm in the crane cabs that indicates when the load is approaching 100 percent of boom capacity. In this case, then, it is appropriate to consider the maximum load the engines will operate to be 320 HP. Thus, Shell proposes to define 100 percent load for these engines as 320 HP.
FD 12-13. Mud Line Cellar Hydraulic Power Unit Engines.
The MLC HPU engines are rated at 322 HP. The PSD permit requires testing at 50-70% and 80- 100% loads.

The se engines power hydraulic pumps that operate hydraulic motors on the MLC bit. The hydraulic motor capacity is limited to 150 gallons per minute at 2500 PSI, which translates to an engine load of about 218 HP. The energy load into the hydraulic motor cannot exceed this value. Given this physical limitation, Shell believes the functional maximum load the engine can operate is at 218 HP, and that we should consider this to be 100% load for testing.
We request EPA’ s written concurrence that testing the starboard crane engine, the Mud Line Cellar Hydraulic Power Unit engines, the Mud Line Cellar Air Compressor engines, the cementing engines and the C7 logging winch engine at an on-shore facility is consistent with th e requirements of the Noble Discoverer PSD permits. We also request EPA’s written concurrence that we can redefine 100 percent load for the main generators, the crane engines, and the Mud Line Cella r Hydraulic Power Unit engines as proposed above. Please contact Pauline Ruddy (907.771.7243) if you have questions or require additional information regarding these proposals.

Thank you,

* Not measured according to ISO8178. Sampling was isokinetic, but not with a dilution tunnel.


### As told in the introduction the PM emission was sampled according to the dust sampling standard EN 13284-1. Then the calculated PM ma ss flow was divided by the average power (as for the specific NO X 

### and CO emissions, cf. page 9 Appendix 3).

Polar Pioneer use MGO with 0.05 w-% S as engine fuel. Based on the composition of the fuel (13.6 w-% H and 86.2 w-% C) the mole fracti on of hydrogen to carbon (H/C ratio) used in the calculations for MGO is 1.8800 [1]. To check if the fuel values used in the calculations are correct, Ecoxy always compares the calculated excess air ratio based on the O 2 

### and CO 2 

### measurements. In Figure 4 the red and blue lines are the theoretical values for the O 2 

### and CO 2 

### concentrations, respectively. The points plotted in the figure are measured values. The figure shows that the measured values are in good accordance with the theoretical values.

TOTAL DERATION FACTORS: This table shows the deration required for various air inlet temperatures and altitudes. Use this information to help determine actual engine power for your site. The total deration factor includes deration due to altitude and ambient temperature, and air inlet manifold temperature deration.

AFTERCOOLER HEAT REJECTION FACTORS: Aftercooler heat rejection is given for standard conditions of 25°C and 150 m altitude. To maintain a constant air inlet manifold temperature, as the air to turbo temperature goes up, so must the heat rejection. As altitude increases, the turbocharger must work harder to overcome the lower atmospheric pressure. This increases the amount of heat that must be removed from the inlet air by the aftercooler. Use the aftercooler heat rejection factor to adjust for ambient and altitude conditions. Multiply this factor by the standard aftercooler heat rejection.

GENERATOR EFFICIENCY: Generator power determined with an assumed generator effeciency of 96% [generator power = engine power x 0.96]. If the actual generator efficiency is less than 96% [and greater than 94.5%], the generator power [ekW] listed in the technical data can still be achieved. The BSFC values must be increased by a factor.

The factor is a percentage = 96% - actual generator efficiency.

SOUND DATA: Data determined by methods according to TM7080.

## SECTION 4. FIRST AID MEASURES

**Inhalation** : Move to fresh air. Give oxygen. If breathing is irregular or stopped, administer artificial respiration. Seek medical attention immediately.
**Skin contact** : Take off all contaminated clothing immediately. Wash off immediately with soap and plenty of water. Wash contaminated clothing before re-use. If skin irritation persists, seek medical attention immediately. **Eye contact** : Remove contact lenses. Rinse thoroughly with plenty of water for at least 15 minutes. If symptoms persist, seek medical attention. **Ingestion** : Do not induce vomiting without medical advice. If a person vomits when lying on his back, place him in the recovery position. Seek medical attention immediately. **Notes to physician** : Symptoms: Dizziness, Discomfort, Headache, Nausea, Disorder, Vomiting, Lung edema, Liver disorders, Kidney disorders. Aspiration may cause pulmonary edema and pneumonitis.



## SECTION 5. FIRE-FIGHTING MEASURES **Suitable extinguishing media** : SMALL FIRES: Any extinguisher suitable for Class B fires, dry chemical, CO2, water spray or fire fighting foam. LARGE FIRES: Water spray, fog or fire fightingfoam. Water may be ineffective for fighting the fire, but may be used to cool fireexposed containers. Keep containers and surroundings cool with water spray. **Specific hazards during fire fighting**  : Fire Hazard Do not use a solid water stream as it may scatter and spread fire. Cool closed containers exposed to fire with water spray. **Special protective equipment for fire-fighters**  : Wear self-contained breathing apparatus and protective suit. Use personal protective equipment.
**Further information** : Exposure to decomposition products may be a hazard to health. Isolate area around container involved in fire. Cool tanks, shells, and containers exposed to fire and excessive heat with water. For massive fires the use of unmanned hose holders or monitor nozzles may be advantageous to further minimize personnel exposure. Major fires may require withdrawal, allowing the tank to burn. Large storage tank fires typically require specially trained personnel and equipment to extinguish the fire, often including the need for properly applied fire fighting foam.



## SECTION 6. ACCIDENTAL RELEASE MEASURES **Personal precautions** : Evacuate nonessential personnel and remove or secure all ignition sources. Consider wind direction; stay upwind and uphill, if possible. Evaluate the direction of product travel, diking, sewers, etc. to contain spill areas. Spills may infiltrate subsurface soil and groundwater; professional assistance may be necessary to determine the extent of subsurface impact. Ensure adequate ventilation. Use personal protective equipment.

## SAFETY DATA SHEET Diesel Low Sulfur (LSD) and Ultra Low Sulfur Diesel (ULSD) Page 4 of 11

4 / 11 **Environmental precautions** : Carefully contain and stop the source of the spill, if safe to do so. Protect bodies of water by diking, absorbents, or absorbent boom, if possible. Do not flush down sewer or drainage systems, unless system is designed and permitted to handle such material. The use of fire fighting foam may be useful in certain situations to reduce vapors. The proper use of water spray may effectively disperse product vapors or the liquid itself, preventing contact with ignition sources or areas/equipment that require protection. Discharge into the environment must be avoided. If the product contaminates rivers and lakes or drains inform respective authorities. **Methods for cleaning up** : Take up with sand or oil absorbing materials. Carefully shovel, scoop or sweep up into a waste container for reclamation or disposal - caution, flammable vapors may accumulate in closed containers. Response and clean-up crews must be properly trained and must utilize proper protective equipment (see Section 8).



## SECTION 7. HANDLING AND STORAGE **Precautions for safe handling** : Keep away from fire, sparks and heated surfaces. No smoking near areas where material is stored or handled. The product should only be stored and handled in areas with intrinsically safe electrical classification. : Hydrocarbon liquids including this product can act as a non-conductive flammable liquid (or static accumulators), and may form ignitable vapor-air mixtures in storage tanks or other containers. Precautions to prevent static-initated fire or explosion during transfer, storage or handling, include but are not limited to these examples: (1) Ground and bond containers during product transfers. Grounding and bonding may not be adequate protection to prevent ignition or explosion of hydrocarbon liquids and vapors that are static accumulators. (2) Special slow load procedures for "switch loading" must be followed to avoid the static ignition hazard that can exist when higher flash point material (such as fuel oil or diesel) is loaded into tanks previously containing low flash point products (such gasoline or naphtha). (3) Storage tank level floats must be effectively bonded. For more information on precautions to prevent static-initated fire or explosion, see NFPA 77, Recommended Practice on Static Electricity (2007), and API Recommended Practice 2003, Protection Against Ignitions Arising Out of Static, Lightning, and Stray Currents (2008). **Conditions for safe storage, including incompatibilities**  : Keep away from flame, sparks, excessive temperatures and open flame. Use approved containers. Keep containers closed and clearly labeled. Empty or partially full product containers or vessels may contain explosive vapors. Do not pressurize, cut, heat, weld or expose containers to sources of ignition. Store in a well-ventilated area. The storage area should comply with NFPA 30 "Flammable and Combustible Liquid Code". The cleaning of tanks previously containing this product should follow API Recommended Practice (RP) 2013 "Cleaning Mobile Tanks In Flammable and Combustible Liquid Service" and API RP 2015 "Cleaning Petroleum Storage Tanks".

: Emergency eye wash capability should be available in the near proximity to operations presenting a potential splash exposure. Keep away from food, drink and animal feed. Incompatible with oxidizing agents. Incompatible with acids.

**Inhalation**

**Skin contact** : Vapors or mists from this material can irritate the nose, throat, and lungs, and can cause signs and symptoms of central nervous system depression, depending on the concentration and duration of exposure.
Skin irritation leading to dermatitis may occur upon prolonged or repeated contact. Liquid may be absorbed through the skin in toxic amounts if large areas of skin are repeatedly exposed. Long-term, repeated skin contact may cause skin cancer. **Eye contact** Eye irritation may result from contact with liquid, mists, and/or vapors. **Ingestion**

**Target organs** Harmful or fatal if swallowed. Do NOT induce vomiting. This material can irritate the mouth, throat, stomach, and cause nausea, vomiting, diarrhea and restlessness Aspiration hazard if liquid is inhaled into lungs, particularly from vomiting after ingestion. Aspiration may result in chemical pneumonia, severe lung damage, respiratory failure and even death.
Central nervous system, Eyes, Skin, Kidney, Liver

**Further information** Studies have shown that similar products produce skin cancer or skin tumors in laboratory animals following repeated applications without washing or removal. The significance of this finding to human exposure has not been determined. Other studies with active skin carcinogens have shown that washing the animal's skin with soap and water between applications reduced tumor formation. Repeated over-exposure may cause liver and kidney injury IARC classifies whole diesel fuel exhaust particulates as carcinogenic to humans (Group 1). NIOSH regards whole diesel fuel exhaust particulates as a potential cause of occupational lung cancer based on animal studies and limited evidence in humans. **Component** : **Fuels, diesel, No 2; Gasoil - unspecified**  68476-34-6 Acute oral toxicity : LD50 rat Dose: 5,001 mg/kg
