 Shipbuilding and Ship Repair (Surface Coating) RTR 

 Preliminary dispersion modeling of the revised ANPRM dataset for surface 

coating operations associated with the shipbuilding and ship repair industry indicated that 

the risk associated with four facilities was estimated to be more than 1-in-1 million. 

Additional data were gathered regarding emissions from these facilities, and revised 

estimates of risk for these facilities indicates none of the revised risks exceed one in a 

million. The additional data gathering efforts and associated adjustment of predicted 

risks are described in this memorandum. 

 The four facilities of concern and the associated predicted risks are shown in 

Table 1. The predicted risks result from emissions of chromium, naphthalene, and nickel. 

The emissions data for these four facilities were based on data in the 2005 NEI database, 

and represent 2002 emissions. The risk analysis is intended to evaluate the risk 

associated with surface coating operations at shipbuilding and ship repair facilities. 

Therefore, for our purposes, only those emissions associated with surface coating 

operations should be included in the risk analysis. Facilities and State agencies were 

contacted to obtain additional detail regarding the types of sources emitting the pollutants 

of concern. 

 The Maryland Department of the Environment was contacted to obtain 

additional information regarding the source of the hexavalent chromium Cr (VI) and 

naphthalene emissions from the U.S. Coast Guard facility in Curtis Bay, Maryland. The 

State contact, Mr. John Eckert, was asked what portion of the Cr (VI) and naphthalene 

emissions for the most recent data available was from surface coating operations. 

 The Maryland Department of the Environment contact indicated that no 

chromium emissions were reported for the Coast Guard facility for 2007 or 2008, and 

that the 2006 chromium emissions (the most recent available) resulted only from welding 

operations. Therefore, for our purposes, the surface coating Cr (VI) emissions were 

assumed to be zero, and the associated risk is zero.

 The 2008 naphthalene emissions from this facility were 48.4 pounds; the 

preliminary risk results were based on an emissions rate of 880 pounds per year. If the 

predicted risk associated with naphthalene emissions (7.36E-06) is multiplied by the ratio 

of the emission rates (48.4/880), the resulting adjusted risk is 4.05E-07, less than 1-in-1 

million. Therefore, the adjusted risk for the Coast Guard facility is less than 1-in-1 

million. 

 The Louisiana Department of Environmental Quality (LDEQ) was contacted 

to determine if the chromium and nickel emissions from the three Louisiana facilities 

resulted from surface coating emissions. Ms. Jackie Heber of LDEQ directed us to the 

plant-wide summary emissions available on their website, and indicated if any additional 

information was desired, an information request must be submitted. Two information 

requests were submitted; one for chromium emissions data, and one for nickel emissions 

data, and the emissions information obtained are summarized in Tables 2 and 3. As can 

be seen in these tables, in 2008 none of the Cr (VI) or nickel emissions at these facilities 

resulted from surface coating operations. Therefore, for our purposes, the risk associated 

with the Cr (VI) and nickel emissions is zero. 

 A printout of the relevant email correspondence between the RTR project 

team and the State agencies is provided at the end of this memorandum.

Mary‐Jo ‐ Ok so here is what I found out. For their  "painting and surface coating operations" in 2007,

they reported 16.8 lbs/year.  For 2008, they reported 48.4 lbs/year. They reported that none came out

of their boilers for either year.

John,

The info. you provided me on chromium emissions from the Coast Guard

facility at Hawkins Point (also referred to as US Coast Guard Curtis Bay ‐ 

NEI33201) was just what I needed.  Thank you.

Now the risk modeling (based on 2002 emissions) indicates a potential

8 
problem due to naphthalene emissions from this facility.  Could you please

tell me what 2008 and 2007 naphthalene emissions were for this facility, and

if the emissions were associated with painting operations?  If there are

emissions, it would be very helpful if you had stack parameters, as right

now we're treating them as a volume source, which probably overstates

impacts.

Thanks very much ‐‐ Mary‐Jo Caldwell

but their report did say it came from welding operations. I don't know enough about welding or

chromium emissions to know what kind of chromium welding would emit.

Mrs Caldwell ‐ When I went into our Emissions Inventory for the US Coast Guard Yard, there were no

reported Chromium emissions for 2007 or 2008. Their 2009 report has not been sent in yet but I would

assume no chromium there either. There was a little bit of chromium in 2006 in the amount of 0.021

tons for the entire year. I also checked the EPA's TRI website which showed no chromium emissions.  

Their MACT reports for 2009 also showed no chromium emissions. I hope this helps. If you have any

further questions let me know.   Thanks – John

Memorandum:  Default Emissions Assumptions

for Shipbuilding and Ship Repair (Surface

Coating) RTR Dataset

14 
August 30, 2010 

MEMORANDUM 

TO: Docket No.: EPA-HQ-OAR-2010-0786 

FROM: Kaye Whitfield, Project Lead 

Risk and Technology Review - National Emission Standards for Hazardous Air 

Pollutants (NESHAP) for Shipbuilding and Ship Repair (Surface Coating) 

SUBJECT: Default Emissions Assumptions for Shipbuilding RTR Dataset 

This memorandum summarizes the approach used to develop default emissions data for the RTR 

dataset for surface coating operations at shipbuilding and ship repair facilities. There are 

approximately 40 shipyards included in our list of ~85 major source (and synthetic minor source) 

shipyards that have missing or incomplete emissions data (based on NEI and TRI searches). 

The following bullets summarize the emissions assumptions being recommended to populate the 

RTR dataset: 

1) For facilities with missing HAP and criteria air pollutants (CAP) emissions data, use the 

following default VOC emissions data: 

-For facilities that emit less than 25 TPY, assign default emissions of 7 tons VOHAP 

(based on average reported emissions from five medium-sized facilities) 

-For facilities that emit greater than or equal to 25 TPY of total HAP, assign default 

emissions of 25 tons VOHAP (based on recommendation by EPA’s Dr. Mohamed 

Serageldin) 

2) For any facility with only actual VOC or default VOC emissions data, use the following 

solvent profile to calculate default HAP emissions from VOC data: 

HAP Solvent Default Profile Synthetic Minor 

Default Emissions

Major Source 

Default Emissions

Xylene (all isomers) 78% 5.5 tons 19.5 tons 

Ethyl benzene 15% 1.0 tons 3.75 tons 

Toluene 7% 0.5 tons 1.75 tons 

Total 100% 7.0 tons 25 tons 

3) There were several ANPRM comments indicating that shipyard painting operations need 

to be modeled as volume sources (instead of point sources); therefore, the default 

volume source parameters to be used for subsequent risk modeling are: 

15 
Exit Gas Temperature (F) – 72 (based on NEI default) 

Exit Gas Velocity (ft/sec) – 0.0003 (based on NEI default) 

Exit Gas Flow Rate (cu ft/sec) – 0 (based on NEI default) 

Fugitive Height (ft) - 10 (based on NEI default) 

Fugitive Width (N-S) (ft) – 100 (based on 1993 Risk Assessment for NASSCO - 

avg of small sources, Docket OAR-2002-0061, 

VIII-D-01) 

Fugitive Length (E-W) (ft) – 100 (based on 1993 Risk Assessment for NASSCO - 

avg of small sources, Docket OAR-2002-0061, 

VIII-D-01) 

Fugitive Angle (degrees) – 0 (based on NEI default)

Facility (NEI 23077)

September 9, 2010

MEMORANDUM

TO:    EPA Docket No.: EPA‐HQ‐OAR‐2010‐0786)

FROM:    Kaye Whitfield, EPA/OAQPS/SPPD

SUBJECT: NASSCO (NEI 23077) – Unspecified Glycol Ether Emissions  

The recent risk modeling results for the shipbuilding and ship repair (surface coating) source

category identified the highest HI and HQ for the NASSCO facility (NEI 23077) located in San Diego, CA.  

The risk driver was 11.4 tons of unspecified glycol ethers based on 2002 NEI data – which defaults to the

most health‐protective glycol ether RfC used as a surrogate for the risk analysis.  The amount of glycol

ethers in the data set appears high by comparison with other large shipyards; therefore, NASSCO was

contacted directly to verify the 11.4 tons of uspecified glycol ether emissions reported in NEI.   

NASSCO Facility Contact:  Sarah Giobbi, Environmental Engineer, 619‐544‐7778

Ms. Giobbi was contacted on 8/3/10, and she informed us that NASSCO reports their annual

material usage to the San Diego Air Pollution Control District.  They reported the following unspecified

glycol ether emissions:

2004 – 2007:          0 lbs

2008:    2,476 lbs

2009:    not finished yet

She also stated that she did not have readily available access to the old (2002) data and NASSCO has not

reported any EGME or DEGBE emissions since 2004.  Five new spray booths and associated controls

were installed in 2009 and will also reduce some of their painting emissions.

Recommendation:  replace NASSCO’s 11.4 tons of unspecified glycol ether emissions with the 2008 data,

where 2,476 lbs (1.24 tons) should be used for the RTR data set.

A copy of NASSCO’s 2008 emissions inventory report is attached.
The San Diego Air Pollution Control District has prepared emission estimates for the above facility.

The purpose of this memorandum is to present additional information related to the five 

major source shipyards that resulted with MIRs between 0.5- and 1-in-1 million in the most 

recent risk modeling using actual emissions. If the current MACT allowable factor of 2 times 

the actual emissions is used in the next risk modeling, these five facilities would have MIR >1-

in-1 million. 

The table below summarizes the available information on these facilities from the RTR data set

Issue 1 – Norfolk Naval Shipyard and Puget Sound Naval Shipyard – Risk driver 

emissions not associated with surface coating operations

The Norfolk Naval Shipyard and Puget Sound Naval Shipyard are part of the Naval 

Sea Systems Command (NAVSEA) division of the United States Navy. The recent risk 

modeling was based on reported emissions for both of these facilities from 2002 NEI 

data. Both facilities were contacted in order to verify that “risk driver” pollutants were in 

fact emitted from surface coating operations subject to the Shipbuilding and Ship Repair 

MACT. After reviewing the facility’s latest annual emissions inventory, environmental 

personnel at the Norfolk Naval Shipyard confirmed that no cadmium emissions (the 

major risk driver – 78%) were emitted from the facility’s surface coating operations.1 

Similarly, the Puget Sound Shipyard confirmed that there 2009 arsenic and methylene 

chloride emissions from surface coating operations were either significantly lower than 

the reported 2002 NEI emissions used in the risk modeling or not associated with coating 

operations. Those emission records associated with non-surface coating operations will 

be corrected in the RTR dataset and will be excluded from the risk analysis for the 

MACT category. Attachment 1 contains the 2009 annual emission reports for the Norfolk 

naval facility. 

Issue 2 – Trinity Industries listed with incorrect NAICS/SIC codes

The Trinity Industries Plant located in Beaumont, Texas is listed in the NEI with 

NAICS code 336510 - Railroad Rolling Stock Manufacturing and an SIC code of 3743 – 

Railroad Equipment.2 The facility was contacted in order to determine whether or not 

shipbuilding or ship repair was performed at the site. A representative of the company 

confirmed that Trinity Industries builds barges at other facilities it owns (located in 

Missouri, Tennessee, and Louisiana) but not at the Beaumont facility.3 Therefore this 

facility should not be listed as a shipbuilding or ship repair facility and all associated 

records should be removed from the RTR data set for the shipbuilding source category. 

Issue 3 – Bollinger Gretna Facility and Detyens Shipyard risk driver emissions listed with 

incorrect SCC codes

The Bollinger Gretna facility and the Detyens Shipyard are both shipbuilding and 

ship repair facilities. The risk driver emissions (propylene oxide and benzene) used for 

the Bollinger Gretna facility in the risk modeling (2002 NEI) were associated with SCC 

30980001 – Industrial Processes Fabricated Metal Products – Equipment Leaks. The risk 

driver emissions (chromium VI) used for the Detyens Shipyard in the risk modeling were 

associated with SCC 30900199 – Industrial Processes Fabricated Metal Products General 

Processes Not Classified. Those emission records associated with these metal fabrication 

SCCs will be corrected in the RTR dataset and not part of the risk analysis for the MACT 

category.

Memorandum:  Summary of Estimated Shipyards

Subject to Shipbuilding and Ship Repair (Surface

MEMORANDUM 

DATE: October 25, 2010 

SUBJECT: Summary of Estimated Shipyards Subject to Shipbuilding and Ship 

Repair (Surface Coating) NESHAP (subpart II) 

FROM: Kaye Whitfield, EPA/OAQPS/SPPD/NRCG 

TO: EPA Docket No. EPA-HQ-OAR-2010-0786

The purpose of this memorandum is to document the current information on the

number of facilities engaged in shipbuilding and ship repair activities and subject to Subpart II:  

1. 85 total (MACT) sources  [~44 major sources + ~41 synthetic minor sources]

- includes all ~20 of the biggest shipyards that were identified in original MACT project

2. 500+ additional facilities in the U.S. that have shipbuilding or ship repair activities, but

are area sources of HAP emissions or not surface coating (MACT) related

3. 71 sources modeled (included in risk analysis report dated July 2010)

- includes 25 facilities that should have been excluded – not part of the 85 (i.e., area

sources or facilities not subject to MACT because they do not build or repair ships)

- therefore, only 46 of the 71 modeled sources are part of the MACT category

- ~15 of the 46 modeled sources include default emissions assigned based on

assumptions

4. 39 additional facilities were identified with missing emissions data Æ not modeled

- typically smaller repair operations with unknown coating usage

- several smaller “sister” operations to nearby major source facilities

- several with missing/unknown NEI ID numbers  

5. The 39 facilities with missing data were identified after the default emissions were

assigned to the other 15 facilities with missing data; there are no technical reasons for

differentiating between any of the 39 + 15 = 54 facilities with missing or incomplete

emissions data.

6. Total number of MACT sources = 46 + 39 = 85
