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 c hromium anodizing tanks (Chromium Electroplating NESHAP) on January 25, 1995 (60 FR 4963). T hese standards are based on the applica tion 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 a n ample margin of safety

to protect public health. If the MACT standar ds “. . . do not reduce lifetime e xcess can cer risk to the indiv

idual most e

xposed to the

emissions. . . to less th

an one in a million,”

EPA must consider f

urther me asures t

o reduce the risk to

accept able levels.

## 2

An assessment of the residual risk associated with sources subject to the Chromium Electroplating NESHAP was initiated in the late 1990's. A residual r isk screening analysis was performed in 1998 and indicated that the residual risk due to hexavalent chr omium emissions exceeded the 1 × 10 -6 

## threshold for 45 of the 63 chromium electroplating fac ilities 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 

## Additiona l analy ses are needed to refine the risk

assessme nt furthe r and to a ccount f or changes in the in

dustry since the se previ ous asses sments were performed. This memorandum presents the da ta needed to perform an additional

as se ss me nt of

re si du al ri sk fo r t he ch ro mi um el ec tr op la ti ng so ur ce ca te go ry.

III. DATA COL

LECTI ON

Since July 2003, RTI I

nternational (RTI) has bee n compiling data on chromium electro plating and anod izing fa cilities in the U.S. B y Jan

uary 2004, approximately

1,800 pla nts that perform chromium electroplating were identified. Using geoprocessing , RTI prepared a series of regional maps showing the loca tions 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 g reatest. During subsequent meetings be tween the Emission Standards Division (ESD) and the Risk and Exposure Assessment Group (REAG), the decision was made to model chromium electroplating emissions for an ur ban area where the cumulative effect of multiple plants could be significant. RTI identified a section of Chicago, Illinois, as the area with the hig hest concentration of chromium electroplating plants in the U.S. At the direction of ESD, RTI contacte d the Illinois EPA and the Chicago Depa rtment of the Environment for additional information on those plants.

In November 2004, RTI

visited the Illinois EPA office in Springfield, I llinois, to collect informat ion on chr

omium elec

troplatin g plants in opera tion in Chic ago. RT I ac cessed p ermit files and made copies of operating per mits, permit applications, Notifications of Compliance Status, Initial Notifications, and other documents that contained informa tion on chromium electroplating operations. These documents, which were used as the basis for the data inputs, are referred to hereafte

r 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 electr oplating or anodizi

ng plan ts were i dentifie d for mode ling. Ta ble 1 lists t

he plants identifie d. As show

n in Table 1, 20 of the 29 plants perform decorative chr omium electroplating, 9 of the plants perform hard chr omium elec

troplatin g; one o f the har

d chromiu

m electr oplating plants als o perfor

ms chromium a

nodizing. Altogether, the 29 plants o

perate 46 hard c hromium el ectropl ating ta nks, 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 ty pes of information needed for modeling and indicates if that infor mation was obtained.

IV. OVERVI

EW OF DATA AND ASSUMPTIONS

For each of the 29 plants, a facility summary sheet is provided in Attac hment 3 with the data inpu ts for mode ling the

residua l risk. Ea ch summar

y sheet inclu

des the st reet ad dress, latitude, and longitude for the facility . In addition, the facility summary sheets provide te chnical information on the chromium electroplating or chromium anodizing tanks in opera tion at the facility. The tan

ks are g rouped a ccordin g to emis sion point. In most cases, a separ ate colu mn is provided for eac h chromiu

m electr oplating tank. However, if

two or mor

e tanks a re exhausted to a common stack, a single column is provided for that gr oup of tanks. Shaded cells on the summary sheets indicate

that the value was assumed. The following para graphs describe the types of data inc luded for each tank (or emission point) and the basis for any assumptions made.

Building Area . This includes the length and height of the longe st wall of the building that house s the t

ank ( in met

ers [m]), an

d the resu lting wall area (in sq uare meters [m

2 

## ]). For 17 of the plants, one or both o f these d imensions were not i

ncluded i n the per mit docume

nts. For t hose plants, the average building wall leng th (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 fenc e line distances were not specified in the permit documents, and those fields were left blank.

Operati ons Sched

ule . Annual operating hours are provided f or typical oper

ations and for the maximum o

peratin g hours allowed by pe

rmit. Ope

rating hours g eneral ly were spe cified in the permit documents in terms of hours per day (hr/day), da

ys per we ek (day/wk) , and weeks per year ( wk/yr). Thus, for

a facility that oper

ates a tank a maximum of 24 hr/day, 7 da ys/wk, and 52 wk/yr, the maximum operating hours a re indicated as 24 × 7 × 52 = 8,736 hr/y r.
For five of the plants, the permit documents do not include either the ty pical or the maximum operating schedule. Fort those cases, the ty pical or maximum operating schedule was estimate d based on the ave rage o f the ra

tios of ty pical to ma

ximum opera

ting hour s for thos e plants that reported both. That average r atio was determined to be 0.75. For example, if a plant reported maximum operating hours but not typic al operating hours, the maximum hours were multiplied by 0.75 to estimate the actual opera ting 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. I

n such cases, the summary sheet shows the operating schedule for the ta nk with the greatest annual operating hours among the group of tanks exhausted with the common ventilati on system.

## 4

Emission Control Method . This field indicates the type of emission control method for each tank. The following acrony ms 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 equ ipped with

hoods and

are ven tilated a nd exhauste d to one or

more stac

ks. For th

ose plants, the point type is listed as “Stack.” F or all other plants, the emission point type is listed as “Fugitive.”

Number o f Emission P oints . In all cases, the number of emission points is listed as one because tanks tha t are exha usted to a common sta

ck are a lready groupe d in the co lumns.

Vent Type . The vent type is indicate d as vertical if the tank is ventilated and exhausted through a stack. I f emissions are fugitive, it is assumed that the emissions are released to the atmosphere via wall-mounted exhaust fans, and the vent ty pe is indicated as non-vertical.

Source Location . The summary shee ts include cells for the latitude and longitude of each emission point. However, the permit documents do not include this information for any of the facilitie s, and thos e cells a re 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 heigh

t and insid

e diamete r are pr ovided in meters.

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

uments inc luded the

height o f the wal l exhaust fa n, and tha t height (in meters) is indicated on the plant summary she ets. For other unventilated tanks, it was assumed that the exhaust poi

nt was loc ated approximately 5 feet ( 1.4 m) bel ow the top of the wa ll. If the wall height was not provided in the permit d ocuments , the def

ault wall height ( 6.4 m) wa s used to calcula te a def ault fugitive sour

ce heig ht of 5.0 m.

Emission L

imit . The applicable emission limit specified in the Chromium Electroplating NESHAP is pr

ovided for each t

ank or g roup of ta nks. The e

mission limit s are spe cified in units of millig rams per dry standar d cubic me

ter (mg /dscm) an d are as follows:

0.015 mg/dscm, for new hard chromium electroplating tanks 0.015 mg/dscm, for existing hard chromium electroplating tanks loca ted at large facilities 0.030 mg/dscm, for existing hard chromium electroplating tanks loca ted at small facilities 0.010 mg/dscm, for all decorative chromium electropla ting 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 c hromium electroplating facilities. A large ha rd 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 y ear (amp-hr/y

r); a small hard chromium electroplating plant is defined as one with a maximum cumulative rectifier c apacity of le ss than 60 million amp-hr/yr.

The next several rows on the facility summary sheets provide inf ormation on emissions from sources that are ventilated and exhausted to stacks. The following paragraphs describe those ent ries.

Actual E mission 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 y ear (kg/y r) using the typical annual ope

rating hours. If te st data were not provided, the actual emission rates wer e estimated in units of g/sec and kg/y r 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 emi ssion factors are as follow s:

Hard ch romium ele ctropla

ting tan k, with CMP: 0.0087 mg/dscm Hard chromium electroplating tank, with MPME: 0.027 mg/dscm Hard ch romium ele ctropla

ting tan k, with PBS : 0.048 mg/dscm Hard ch romium ele ctropla

ting tan k, with FBand PBS: 0.0060 mg/dscm Decora tive chr omium elec

troplatin g tank, with WAFS: 0.0027 mg/dscm

When the above emission factors are compared to the e mission limits, it is apparent that actual emissions for a hard chromium electroplating ta nk that is controlled with a PBS (emission factor = 0.048 mg/dscm) would be estimated to exceed the e mission limit, regardless of whether or not the facility was small

(emission

limit = 0.03 0 mg/dscm) or a ne w or large facili

ty (emission limit = 0.015 mg/dscm). In addition, actual emissions for a har d 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 f acilities. 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 a

re indic ated on the summary sheet to b e grea

ter than emissions a

t the emiss ion limit.

Emissions a

t the Emissi on Lim

it . The next three rows in the summary sheets indicate the maximum emission rate (in units of g/sec) if the sources were opera ting at the emission limit. These e mission ra

tes were determined using

the volume

tric flow rates sp ecified

in the per

mit documents. Because the flow rates we re reported in units of actual cubic feet pe r 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 re quires values for the stack gas temper ature, 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 Chromi

um Electr oplating NESHAP. 3 

## None of the permit documents specified the stack g as moisture content or pressure. Consequently, a default moisture content of 2 percent was used, which als o is based

on the mode l plants for the NESH AP. 3 

## For the stack gas pressure, it was assumed that the pressure was equal to the standard pre ssure 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 opera

ting 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 mode l plant tank flow
rate wa s used by

selectin g the mod el electroplatin

g tank that most clo sely

matched the fac ility 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/y r were determined using the same procedure described in the pre vious 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. F or that plant, emissions were estimated using the reported flow ra te, as well as the model plant tank flow rate.

Gas Exit Ve locity . The gas exit velocity is provide d in units of meters per second (m/sec) based on the reported actual flow rate a nd stack diameter. Stack diameters were not re ported for two of the plants; for those plants, model plant stack diameters were used.

Gas Exit Temperature . The gas exit temperature in units of degree s Kelvin (°K) are provided based on the exit gas temperatures repor ted in the permit documents. If the exit gas temperature was not specified, a defa ult value of 300°K is indicated, based on the model plant stack gas temp erature 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 consequen tly,are tre ated as fugitive emission sources . Those ta nks all

are use d for dec orative

chromium e lectrop lating. The following pa ragra phs descr ibe those entries o n the summa

ry sheets.

Estimated Actual E mission Rate . Because the emission limits specified in the Chromium Electroplating NESHAP are in units of concentration, a f low rate is required to estimate emission rates at the emission limit. However, there are no flow ra tes associated with chromium electroplating tanks that are not ventilated and exhausted. Ther efore, emissions cannot be estimated at the emission limit for those sources. Instead, the e mission 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/a mp-hr) for uncontrolled emissions from decorative

## 7

chromium e lectrop lating ta nks. 4 

## Using this emission factor and the rectifier capa cities specified in the permit documents, uncontrolled emissions can be estimated. Because the se tanks all are controlle d with wet

ting agent fume

suppress ants, a c ontrol ef ficienc y mu st be appl ied to esti

mate actual emissions. For these estimates, a control efficienc y of 99.5 perc ent was used, based on the post-MACT emissions estimates presented in the Background I nformation Document for the proposed NESHAP. 3 

## The next two rows in the summary sheets indicate a

nnual emi ssions in units of kg/yr f

or typical and maximum operating hours, respectively . Attachment 2 shows an example of the calculations of fugitive emissions from an unventilated decor ative chromium electroplating tank.

Gas Exit Ve locity . Because these tanks are not ventilated a nd exhausted, the exit gas velocity is indicated as ne gligible.

Gas Exit Temperature . For these tanks, the default value of 300°K is indicated in the summary sheets. Th is is based on the model plant stack gas temperature o f 80°F. 3



## Other Information . The last section of the summary sheets provides other relevant informat ion for c ertain p lants. For example,this secti on indica tes that f our of the plants ope

rate vapor degreasers that ar

e subject to 40 CFR 63, subpart T (Halogenated Solvent Cleaning NESHAP). For other plants, this section provides additional information that was used to make assumption s on flow r

ates or other re levant pa

rameter s.
