# Technical Memorandum

DATE: July 11, 2012

SUBJECT: Summary of Cooling Water Systems Emission Source Test R eports

I. Purpose

The objective of this document is to provide a summary o f the cooling water systems

emission source test reports received by the EPA from the 2011 Information Collection Request

(ICR) of the petroleum refinery industry.

II. Background

On April 1, 2011, the EPA sent an ICR to facilities in the U.S. petroleum refining

industry. The ICR was comprehensive and designed to collect i nformation on processing

characteristics, crude slate characteristics, emissio ns inventories and source testing to bolster our

current data and fill known data gaps. The ICR had four com ponents: (1) a questionnaire on

processes and controls to be completed by all petroleum r efineries (Component 1); (2) an

emissions inventory to be developed by all petroleum refineri es using the emissions estimation

protocol developed for this effort (Component 2); (3) distil lation feed sampling and analysis to

be conducted by all petroleum refineries (Component 3); and ( 4) emissions source testing to be

completed in accordance with an EPA-approved protocol for specific sources at specific

petroleum refineries (Component 4).

Component 4 of the ICR requested source testing for twelve different types of emission

sources or units: fluid catalytic cracking units (FCCU), t hermal catalytic cracking units, catalytic

reforming units, sulfur recovery units, delayed coking units, fl uid coking units, hydrocracking

units, hydrogen plants, asphalt blowing units, fuel gas systems, cooling water systems, and

wastewater treatment systems. This memorandum summari zes the results of the cooling water

systems source tests. A similar memorandum is available for the other emission sources required

to be tested as a result of this ICR.

# 2

Facilities often claimed specific process information a s CBI, and included that

information in the CBI version of the emission sourc e test report stored in the EPA’s CBI office

in Research Triangle Park, NC. However, emissions dat a cannot be claimed as CBI. This

memorandum summarizes and presents only non-CBI data.

III. Source-specific Testing Program

Below is a list of facilities required to test their c ooling water systems:

• Suncor Energy (U.S.A.) Inc. Commerce City Refinery – C ommerce City, CO

(CO4A0340)

• Alon USA Krotz Springs Refinery – Krotz Springs, LA (LA3 C0700)

• Western Refining Gallup Refinery – Jamestown, NM (NM3E0880)

• Wynnewood Refining Company – Wynnewood, OK (OK2C0960)

• United Refining Co – Warren, PA (PA1B1050)

• Valero McKee Refinery – Sunray, TX (TX3A1300)

• Pasadena Refining System Inc. – Pasadena, TX (TX3B1150)

• Holly Refining & Marketing Company - Woods Cross Refinery – Woods Cross, UT

(UT4A1380)

• BP West Coast Products LLC – Blaine, WA (WA5A1400)

• Murphy Oil USA, Inc. Superior Refinery – Superior, WI (WI2B1460)

• Frontier Refining, Inc. – Cheyenee, WY (WY4A1470)

Owners or operators of the cooling water systems at th ese facilities were required to test

for total strippable volatile organic compounds (VOC) using Mo dified El Paso Method (Air

Stripping Method for Determination of Volatile Organic Com pound Emissions from Water

Sources, Revision Number One, dated January 2003, Sampling Pr ocedures Manual, Appendix P:

Cooling Tower Monitoring, prepared by Texas Commission on Enviro nmental Quality, January

31, 2003). Following Modified El Paso testing, additional tes ting was performed on the cooling

water system with the highest total strippable hydrocarbon concentration, except for the

following situations: if more than one cooling water sy stem return line had total strippable

hydrocarbon concentration greater than 62 ppmv, then the facility conducted additional testing

for all cooling water systems that had a return line co ncentration greater than 62 ppmv; and if

none of the cooling water system return lines had a tota l strippable hydrocarbon concentration

# 3

greater than or equal to 3 ppmv, then the facility conducted additional testing only for HCl and

Cl 2 

# for any one cooling water system return line. The addit ional testing included:

• Speciated volatile organic hazardous air pollutants (HAP)

• Speciated semi-volatile organic HAP

• Formaldehyde

• Total hydrocarbons

• Methane

• Hydrogen chloride and chlorine

A summary of the testing each facility conducted is prov ided in Table 1. It appears that

four facilities did not provide the results of Modified El Paso Method testing (NM3E0880,

OK2C0960, WI2B1460, WY4A1470); however, these facilities did conduct other cooling water

analysis.

Additional detail of the source testing requirements fo r the cooling water systems sources

can be found at http://www.epa.gov/ttn/atw/petref/petrefpg.html

.

The EPA required that the data collected from the emiss ion source testing to be reported

using the EPA Electronic Reporting Tool (ERT). The ERT is a Microsoft® Access database

application. If the facility conducted testing using a meth od not currently supported by the ERT,

such as the required testing for cooling towers, the faci lity was required to report the results in

the Refinery Testing Supplement, a Microsoft® Excel sprea dsheet. After completing the

Refinery Testing Supplement, the refineries were also as ked to submit an electronic copy of the

emission test report, preferably in PDF format.

IV. Results

A list of the cooling water systems that were tested i s provided in Table 2, and a

summary of the emission results for the cooling water systems are provided in Table 3. In order

to better characterize the reported data from the emis sion test reports, detection level information

was provided in the attached summary spreadsheet. The fol lowing designations were used to

describe the detection levels of the reported emissions data.

• DLL = Detection Level Limited = 1 or 2 runs below detec tion limit

• BDL = Below Detection Limit = All three runs are bel ow detection limit

• No designation = All three runs are above detection lim itTable 1.

a HAP.1 Facility did not provide a copy of the test report.2 Red text indicates that the default values for flows specified in the method, atmospheric P, and average ambient temperature were used. For cooling water tests conducted in the Summer of 2011, assumedthat the apparatustemperature was at least 90F (32C).3 The facility calculated the concentration in thewater based on the air concentration, and providedthe value.4 Compare to measured water concentration, below.5 Compound was BDL in the measured air.6 The facility calculated the mass emission rate and provided the value.7 The facility provided calculated values for thewater concentration and the mass emission rate, butthere appeared to be a problem with the calculation (facility used 2.5 mL/min for the air flow ratherthan 2,500 mL/min).8 Measured air concentration is not provided as methane; in determining the water concentration and the mass emission rate, the air concentration was converted to methane.9 The emissions from the cooling tower are estimated based on the measured water concentration and the cooling tower water flowrate (see cooling tower flowrate values in Table 2); this estimate assumes that all of the compoundpresent in the water volatilizes.10 The test report for this cooling tower presentswater concentrations in ug/L and shows these values as being equivalent to ppmw, however, there appeared to be a problem; we assumed the water concentrations werein ug/L and ppbw.
