I. INTRODUCTION

This memorandum presents the data inputs for modeling the residual risk due to

chromium emissions from 29 chromium electroplating plants located in Chicago, Illinois. 

Section II provides background information on the residual risk assessment for the source

category. Section III describes how the facilities were selected for modeling. Section IV

provides an overview of the data and the basis for all assumptions and emission estimates. 

References are listed in Section V. Example calculations of stack and fugitive emissions are

provided in Attachments 1 and 2, respectively. The data inputs for each plant are provided in the

facility summary sheets that comprise Attachment 3.

II. BACKGROUND

Under Section 112 of the Clean Air Act (CAA), national emissions standards for

hazardous air pollutants (NESHAP) were promulgated for chromium emissions from hard and

decorative chromium electroplating and chromium anodizing tanks (Chromium Electroplating

NESHAP) on January 25, 1995 (60 FR 4963). These standards are based on the application of

the maximum achievable control technology (MACT). Section 112(f)(2) of the CAA directs the

U.S. Environmental Protection Agency (EPA) to assess the post-MACT standard risk (residual

risk) within 8 years of promulgation of MACT standards to ensure that the standards provide an

ample margin of safety to protect public health. If the MACT standards “. . . do not reduce

lifetime excess cancer risk to the individual most exposed to the emissions. . . to less than one in

a million,” EPA must consider further measures to reduce the risk to acceptable levels.

An assessment of the residual risk associated with sources subject to the Chromium

Electroplating NESHAP was initiated in the late 1990's. A residual risk screening analysis was

performed in 1998 and indicated that the residual risk due to hexavalent chromium emissions

exceeded the 1 × 10-6 threshold for 45 of the 63 chromium electroplating facilities modeled.1 A

refined risk analysis, which focused on 14 of the 63 plants and also was completed in 1998,

found that the residual risk due to hexavalent chromium emissions exceeded the threshold of

1 × 10-6 for 8 of 14 facilities modeled.2 Additional analyses are needed to refine the risk

assessment further and to account for changes in the industry since these previous assessments

were performed. This memorandum presents the data needed to perform an additional

assessment of residual risk for the chromium electroplating source category.

III. DATA COLLECTION

Since July 2003, RTI International (RTI) has been compiling data on chromium

electroplating and anodizing facilities in the U.S. By January 2004, approximately 1,800 plants

that perform chromium electroplating were identified. Using geoprocessing, RTI prepared a

series of regional maps showing the locations of chromium electroplating facilities nationwide.

In addition, RTI mapped the facilities in several urban areas where the concentration of

chromium electroplating plants appeared to be greatest. During subsequent meetings between

the Emission Standards Division (ESD) and the Risk and Exposure Assessment Group (REAG),

the decision was made to model chromium electroplating emissions for an urban area where the

cumulative effect of multiple plants could be significant. RTI identified a section of Chicago,

Illinois, as the area with the highest concentration of chromium electroplating plants in the U.S. 

At the direction of ESD, RTI contacted the Illinois EPA and the Chicago Department of the

Environment for additional information on those plants. 

In November 2004, RTI visited the Illinois EPA office in Springfield, Illinois, to collect

information on chromium electroplating plants in operation in Chicago. RTI accessed permit

files and made copies of operating permits, permit applications, Notifications of Compliance

Status, Initial Notifications, and other documents that contained information on chromium

electroplating operations. These documents, which were used as the basis for the data inputs, are

referred to hereafter in this memorandum as the “permit documents” and are listed in Section V

of this memorandum.

Based on the information contained in the permit documents, 29 chromium electroplating

or anodizing plants were identified for modeling. Table 1 lists the plants identified. As shown in

Table 1, 20 of the 29 plants perform decorative chromium electroplating, 9 of the plants perform

hard chromium electroplating; one of the hard chromium electroplating plants also performs

chromium anodizing. Altogether, the 29 plants operate 46 hard chromium electroplating tanks,

41 decorative chromium electroplating tanks, and one chromium anodizing tank. Three of the

decorative tanks use a trivalent chromium bath. Table 1 also lists some of the other types of

information needed for modeling and indicates if that information was obtained.

IV. OVERVIEW OF DATA AND ASSUMPTIONS

For each of the 29 plants, a facility summary sheet is provided in Attachment 3 with the

data inputs for modeling the residual risk. Each summary sheet includes the street address,

latitude, and longitude for the facility. In addition, the facility summary sheets provide technical

information on the chromium electroplating or chromium anodizing tanks in operation at the

facility. The tanks are grouped according to emission point. In most cases, a separate column is

provided for each chromium electroplating tank. However, if two or more tanks are exhausted to

a common stack, a single column is provided for that group of tanks. Shaded cells on the

summary sheets indicate that the value was assumed. The following paragraphs describe the

types of data included for each tank (or emission point) and the basis for any assumptions made.

Building Area. This includes the length and height of the longest wall of the building that

houses the tank (in meters [m]), and the resulting wall area (in square meters [m2]). For 17 of the

plants, one or both of these dimensions were not included in the permit documents. For those

plants, the average building wall length (46.6 m) and height (6.4 m) were assumed.

Fence Line. The distance in meters from the emission point to the fence line is provided

where possible. For 11 of the 29 facilities, the fence line distances were not specified in the

permit documents, and those fields were left blank.

Operations Schedule. Annual operating hours are provided for typical operations and for

the maximum operating hours allowed by permit. Operating hours generally were specified in

the permit documents in terms of hours per day (hr/day), days per week (day/wk), and weeks per

year (wk/yr). Thus, for a facility that operates a tank a maximum of 24 hr/day, 7 days/wk, and

52 wk/yr, the maximum operating hours are indicated as 24 × 7 × 52 = 8,736 hr/yr. 

For five of the plants, the permit documents do not include either the typical or the

maximum operating schedule. Fort those cases, the typical or maximum operating schedule was

estimated based on the average of the ratios of typical to maximum operating hours for those

plants that reported both. That average ratio was determined to be 0.75. For example, if a plant

reported maximum operating hours but not typical operating hours, the maximum hours were

multiplied by 0.75 to estimate the actual operating hours for the plant. If a plant reported actual

but not maximum operating hours, the actual hours were divided by 0.75 to estimate maximum

hours. 

For a few of the facilities that have two or more tanks exhausted to a common stack, the

operating schedules are not identical for all of the tanks that are served by the same exhaust and

ventilation system. In such cases, the summary sheet shows the operating schedule for the tank

with the greatest annual operating hours among the group of tanks exhausted with the common

ventilation system.
4

Emission Control Method. This field indicates the type of emission control method for

each tank. The following acronyms are used to indicate the control method:

FB: foam blanket

PBS: packed bed scrubber

WAFS : wetting agent fume suppressant

MPME: mesh pad mist eliminator

CMP: composite mesh pad

Emission Source Point Type. At 17 of the 29 plants, the chromium electroplating tanks

are equipped with hoods and are ventilated and exhausted to one or more stacks. For those

plants, the point type is listed as “Stack.” For all other plants, the emission point type is listed as

“Fugitive.”

Number of Emission Points. In all cases, the number of emission points is listed as one

because tanks that are exhausted to a common stack are already grouped in the columns.

Vent Type. The vent type is indicated as vertical if the tank is ventilated and exhausted

through a stack. If emissions are fugitive, it is assumed that the emissions are released to the

atmosphere via wall-mounted exhaust fans, and the vent type is indicated as non-vertical. 

Source Location. The summary sheets include cells for the latitude and longitude of each

emission point. However, the permit documents do not include this information for any of the

facilities, and those cells are blank on all of the summary sheets.

Point Source Stack Height and Diameter. For sources that are ventilated and exhausted

through a stack, the stack height and inside diameter are provided in meters.

Fugitive Source Stack Height. For a few of the facilities with unventilated tanks, the

permit documents included the height of the wall exhaust fan, and that height (in meters) is

indicated on the plant summary sheets. For other unventilated tanks, it was assumed that the

exhaust point was located approximately 5 feet (1.4 m) below the top of the wall. If the wall

height was not provided in the permit documents, the default wall height (6.4 m) was used to

calculate a default fugitive source height of 5.0 m.

Emission Limit. The applicable emission limit specified in the Chromium Electroplating

NESHAP is provided for each tank or group of tanks. The emission limits are specified in units

of milligrams per dry standard cubic meter (mg/dscm) and are as follows:

0.015 mg/dscm, for new hard chromium electroplating tanks

0.015 mg/dscm, for existing hard chromium electroplating tanks located at large facilities

0.030 mg/dscm, for existing hard chromium electroplating tanks located at small facilities

0.010 mg/dscm, for all decorative chromium electroplating tanks

0.010 mg/dscm, for all chromium anodizing tanks
5

With respect to emission limits, the Chromium Electroplating NESHAP differentiates

between large and small hard chromium electroplating facilities. A large hard chromium

electroplating facility is defined in §63.341(a) as one with a maximum cumulative rectifier

capacity of at least 60 million ampere-hours per year (amp-hr/yr); a small hard chromium

electroplating plant is defined as one with a maximum cumulative rectifier capacity of less than

60 million amp-hr/yr.

The next several rows on the facility summary sheets provide information on emissions

from sources that are ventilated and exhausted to stacks. The following paragraphs describe

those entries.

Actual Emission Rate. For four plants, the permit documents include the results of

emission tests on one or more chromium electroplating tanks. For those cases, the measured

emission rate is provided in grams per second (g/sec), and kilograms per year (kg/yr) using the

typical annual operating hours. If test data were not provided, the actual emission rates were

estimated in units of g/sec and kg/yr using the appropriated emission factor from Section 12.20,

Electroplating, of Compilation of Air Pollutant Emission Factors, Stationary and Point Sources

(AP-42).4 Those emission factors are as follows:

Hard chromium electroplating tank, with CMP: 0.0087 mg/dscm

Hard chromium electroplating tank, with MPME: 0.027 mg/dscm

Hard chromium electroplating tank, with PBS: 0.048 mg/dscm

Hard chromium electroplating tank, with FB and PBS: 0.0060 mg/dscm

Decorative chromium electroplating tank, with WAFS: 0.0027 mg/dscm

When the above emission factors are compared to the emission limits, it is apparent that

actual emissions for a hard chromium electroplating tank that is controlled with a PBS (emission

factor = 0.048 mg/dscm) would be estimated to exceed the emission limit, regardless of whether

or not the facility was small (emission limit = 0.030 mg/dscm) or a new or large facility

(emission limit = 0.015 mg/dscm). In addition, actual emissions for a hard chromium

electroplating tank controlled with an MPME (emission factor = 0.027 mg/dscm) would be

estimated to exceed the emission limit of 0.015 mg/dscm for new or large facilities. The reason

for this anomaly is that the emission factors are based on tests on several tanks. For some of

those tanks, the control device may not have been indicative of the capabilities of the control

technology when it is well designed and/or well maintained. 

Some of the plants considered for this exercise use either PBSs or MPMEs to control

emissions from hard chromium electroplating tanks. However, for all but one of those plants, the

permit documents include the results for emission tests that demonstrate compliance with the

applicable emission limit. For the one exception (Empire Hard Chrome, South Kostner), actual

emissions are indicated on the summary sheet to be greater than emissions at the emission limit.

Emissions at the Emission Limit. The next three rows in the summary sheets indicate the

maximum emission rate (in units of g/sec) if the sources were operating at the emission limit. 

These emission rates were determined using the volumetric flow rates specified in the permit

documents. Because the flow rates were reported in units of actual cubic feet per minute and the
6

emission limits for the Chromium Electroplating NESHAP are specified in mg/dscm, it was

necessary to convert the reported flow rates to dry standard cubic meters per minute (dscm/min). 

In addition to the flow rate, this conversion requires values for the stack gas temperature,

pressure, and moisture content. Many of the permit documents specified a stack gas temperature. 

For those that did not, a default value of 80°F was used, based on the model plants developed for

the Chromium Electroplating NESHAP.3 None of the permit documents specified the stack gas

moisture content or pressure. Consequently, a default moisture content of 2 percent was used,

which also is based on the model plants for the NESHAP.3 For the stack gas pressure, it was

assumed that the pressure was equal to the standard pressure of 29.92 inches of mercury. After

converting the flow rates to units of dscm/min, the maximum emission rates were calculated. 

The next two rows in the summary sheets indicate annual emissions in units of kg/yr based on

typical operating hours and on the maximum operating hours, respectively. Attachment 1 shows

an example of the calculations for one tank.

For one of the plants that exhausts chromium electroplating tank emissions to a stack, the

permit documents do not provide the actual flow rate. For that plant, the model plant tank flow

rate was used by selecting the model electroplating tank that most closely matched the facility

tank in terms of tank dimensions and rectifier capacity. Using that model plant flow rate, the

maximum emission rate in g/sec and annual emission rates in kg/yr were determined using the

same procedure described in the previous paragraph and illustrated in Attachment 1. For another

plant, the permit documents indicated that tank emissions were exhausted through a common

system that exhausted other, nonchromium electroplating tanks. The flow rate for the entire

system was provided. For that plant, emissions were estimated using the reported flow rate, as

well as the model plant tank flow rate.

Gas Exit Velocity. The gas exit velocity is provided in units of meters per second (m/sec) 

based on the reported actual flow rate and stack diameter. Stack diameters were not reported for

two of the plants; for those plants, model plant stack diameters were used.

Gas Exit Temperature. The gas exit temperature in units of degrees Kelvin (°K) are

provided based on the exit gas temperatures reported in the permit documents. If the exit gas

temperature was not specified, a default value of 300°K is indicated, based on the model plant

stack gas temperature of 80°F.3 

The last five rows on the summary sheets apply only to tanks that are not ventilated and

exhausted to a stack, and consequently, are treated as fugitive emission sources. Those tanks all

are used for decorative chromium electroplating. The following paragraphs describe those

entries on the summary sheets.

Estimated Actual Emission Rate. Because the emission limits specified in the Chromium

Electroplating NESHAP are in units of concentration, a flow rate is required to estimate emission

rates at the emission limit. However, there are no flow rates associated with chromium

electroplating tanks that are not ventilated and exhausted. Therefore, emissions cannot be

estimated at the emission limit for those sources. Instead, the emission factors from AP-42 were

used to estimate actual emissions. Section 12.20 of AP-42 specifies an emission factor of

2.1 milligrams per ampere-hour (mg/amp-hr) for uncontrolled emissions from decorative
7

chromium electroplating tanks.4 Using this emission factor and the rectifier capacities specified

in the permit documents, uncontrolled emissions can be estimated. Because these tanks all are

controlled with wetting agent fume suppressants, a control efficiency must be applied to estimate

actual emissions. For these estimates, a control efficiency of 99.5 percent was used, based on the

post-MACT emissions estimates presented in the Background Information Document for the

proposed NESHAP.3 The next two rows in the summary sheets indicate annual emissions in

units of kg/yr for typical and maximum operating hours, respectively. Attachment 2 shows an

example of the calculations of fugitive emissions from an unventilated decorative chromium

electroplating tank.

Gas Exit Velocity. Because these tanks are not ventilated and exhausted, the exit gas

velocity is indicated as negligible.

Gas Exit Temperature. For these tanks, the default value of 300°K is indicated in the

summary sheets. This is based on the model plant stack gas temperature of 80°F.3

Other Information. The last section of the summary sheets provides other relevant

information for certain plants. For example, this section indicates that four of the plants operate

vapor degreasers that are subject to 40 CFR 63, subpart T (Halogenated Solvent Cleaning

NESHAP). For other plants, this section provides additional information that was used to make

assumptions on flow rates or other relevant parameters.

EXAMPLE CALCULATIONS FOR TANK EXHAUSTED TO STACK

1. Conversion of Actual Flow Rate to Standard Flow Rate

Equation

Qsd = Qa ×(1-(Bws/100)) × (Tstd/(ts + 460)) × Ps/Pstd)

Where:

Qsd = Volumetric flow rate, dry standard cubic meters per minute (dscm/min)

Qa = Volumetric flow rate, actual cubic meters per minute (acm/min)

Bws = Stack gas moisture content (percent)

Tstd = Standard temperature (°R) = 528°R

t

s = Stack gas temperature (°F)

Pstd = Standard pressure (inches of mercury [in. Hg]) = 29.92 in. Hg

Ps = Stack gas pressure (in Hg)

Example Calculation

Assume actual flow rate is 160 acm/min, the stack gas moisture content is 2.0 percent, the

stack gas temperature is 80°F, and the stack gas pressure is 29.92 in. Hg.

Qsd = 160 acm/min ×(1 - (2.0/100)) × (528/(80 + 460)) × 29.92/29.92) = 153 acm/min

2. Determination of Maximum Emission Rate at the Emission Limit

Equation

Emax = Qsd × EL

Where:

Emax = Maximum emission rate at the emission limit, grams per second (g/sec)

Qsd = Volumetric flow rate, dry standard cubic meters per minute (dscm/min)

EL = Emission limit, milligrams per dry standard cubic meter (mg/dscm)

Example Calculation

Assume the flow rate is 153 dscm/min, and the emission limit is 0.015 mg/dscm.

Emax = 153 dscm/min × 0.015 mg/dscm × 1 min/60 sec × 1 g/1,000 mg = 3.83×10-5 g/sec
3. Determination of Annual Emissions at the Emission Limit

Equation

Ean = Emax × Han

Where:

Ean = Annual emissions, kilograms per year (kg/yr)

Emax = Maximum emission rate at the emission limit, g/sec

Han = Annual operating hours, hours per year (hr/yr)

Example Calculation

Assume the same tank in the previous example operates 1,040 hr/yr.

Ean = 3.83×10-5 g/sec × 1,040 hr/yr × 1 kg/1,000 g × 3,600 sec/hr = 0.143 kg/yr
Attachment 2

EXAMPLE CALCULATIONS FOR FUGITIVE EMISSIONS

1. Determination of Actual Emission Rate

Equation

Eact = EF × Rc × (1 - Ec/100)

Where:

Eact = Actual emission rate, grams per second (g/sec)

EF = Emission factor = 2.1 milligrams per ampere-hour (mg/amp-hr)

Rc = Rectifier capacity, amp

Ec = Control efficiency = 99.5 percent

Example Calculation

Assume the rectifier capacity is 5,000 amp.

Eact = 2.1 mg/amp-hr × 5,000 amp × (1 - 99.5/100) × 1 g/1,000 mg × 1 hr/3,600 sec 

= 1.46 ×10-5 g/sec

2. Determination of Actual Annual Emissions

Equation

Ean = Eact × Han

Where:

Ean = Annual emissions, kilograms per year (kg/yr)

Eact = Actual emission rate, g/sec

Han = Annual operating hours, hours per year (hr/yr)

Example Calculation

Assume the same tank in the previous example operates 5,280 hr/yr.

Ean = 1.46×10-5 g/sec × 5,280 hr/yr × 1 kg/1,000 g × 3,600 sec/hr = 0.277 kg/yr
