Thi s methodology allows the model er to use one s et of modeling runs and scal e the results by m ulti plying th em by the a ctual or tested emission rate.

### leav e the study area without depositin g . 

## n.e fraction of a pollutant that remains in the vapor phase in the swrounding area is identified in the

### F. is calculated for both elemental and divalent mercury. Divalent meri:ury is 

### modeled as mercuric chloride. Tbe risk assessment model combines all of these foctors to scale the results from the dispersion modeling and deposi tion resu l ts to s ite-specifi c air concentrations and deposition nuxes for tbe different species and

### For**rneth l~** **ry .**  U .S. 

### EPA g uid an ce rec ommends lhatthe conc tntr ation in 

### fish sho ul d be calculated using a methylmercury - specific Bioaceumulation Factor (BAF) . Th e BAF is th e ratio o f the contaminant concentrati o n i n fish tissue t O lhe contaminant concentration in the wateibody w he re the fish 

### an: exposed 10 the co ntaminant The BAF 

### accounts for upcak.e of 

### concaminants into 

### fish by a combina ti on of several different mechanisms including water passing 

### across the gills 

### and consumption o f sediments and dieW"y foods which could include plankton , d aphnids , 

### and ot her fish. BAP values are based on dissolved wattr co ncentration s . U . S. EPA guidance recommends the f ollow i ng equation to calculate fish concentrations for chemicals which bioaccumulate including methylmercury (HHRAP): 

### CmJ,

### faaor fOf' rnelby l mercliry (Uterlkg) The dissolved 

### phase water concentration (Ct.) is calculated 

### as described above (Sect ion 

### B.2 . ). The recommended methylmercury BAPr,.., value and th e BAF value used in the 

### Veolia Risk. Report is 

### 6 . 8E-+06 (llliRAP Chemdat Database). That BAF value i s based on the !l""llletric mean from measured BAF values oblained from a nu mber of aclual fieklstudiC$ of mcn:ury bioaocurnulation eoo<lucled at U.S . and Canadian lakes (Mercury Study Report) . This value is considered to be appropriace for evaluating methylmercury uptake at olher lak.C3 and also accounts Cor uptake into fish at a high crophic level (i.e. , trophlc level 4 - fish at the highest end of the food c h ain). The available i nformatio n indicates that the lakes at Fran k Holten State Pari: contain fish at lrophic l evel 4. 

### 4 . Flsb Consum pti on 

### R a t e During the 2003 public co rnrnenl period, the public raised the concern that U.S. EPA had not**~onsidered** subsistence fishing at the 

### Prank Holten Stale Park lak.ea. 

### 1n addition, reports of subsistence fishing were provi d ed to U.S . EPA. Visits to the lake's 

### by U.S. EPA indicated the potent i al 

### for recreational and subs i stence fishing there . Frank. Hollen Sta te 

### Park. lakes have naiUrally occurring fish 

### and aie 

### s lock.cd annually wi th game fish. I n addiliorc. U. S. EPA has concluded ll>at the area surrounding the 

### Veolia facili t y is a potential environmen t al juslice community. For these reasons, U.S. EPA u s ed Adult 

### and Child Fisher exposure 

### scenarios recommended 

### by 

### l:D1RAP for asses sin g potencial risks posed 

### by methylmercury in fish.

### VES 0 0 7 7711.6 Modlficalious to Procedure 

### Onyx has prepared several drafts of this report for review l> y U.S . EPA Region 5 

### and lllinois EPA. The first Scr•ening Ri sk Assessment , sul>mitted for review in Septeml>er 2004 , 

### was bused 

### on a protocol submitted to 

### U . S . EPA in 

### July 2004. This screeni ng leve l risk a!ises s ment utilized many conservative default values . In 

### May 2005, Onyx submitted a revised screening level risk assessmeni th a t in c l uded many defaults , but 

### utilized mercury concentrat i ons from fish 

### sampled 

### from the 

### Frank Holten 

### Lakes . Hazard qu ouents for mercury were calculated usin g this analytJcal data , rather tluln the default fate and transport equatioos provided in the 

### HHRAP. During 

### the execution of this final risk assessment report, 

### a number of the default melhods, value s , or vnriables were determined to be innppropriate fo r use in this application . In 

### some cas e s, values srated in the 

### protocol were incorrectly st'8ted . In 

### other cases, awarooess of more approp ri ate site· specific information was included to more accurately sunulate hazard and 

### risk. The issuance of the Fina l HHRAP in September 2005 a l so indicated changes to some methodol ogies previo'!sly 

### docwnented in the 

### Draft HHRAP . The following 

### paragrnphs de t ail revisions made in the 

### risk assessment evaluation for the above purposes since the original protoco l. This report represents a conservative approximation of risk and hazard 

### from hypothetical worst -cas o incinerator emissions 

### if each incinemtor is operating long-term at the MACT emission limit for each constiruent. 

### The modifications 

### made i n performing the 

### risk assessmen t re l ated to air modeling since the submittal 

### ofthe protocol are: 

### • The risk assessment 

### area and i t s associated land usc and land classificatio n were carefully considered in performing this assessment. A 

### detailed land use study was perfonned that indicated a near 

### 50150 split between urban and rural land use . Tbe methodology by wbicb land use ca tegories were 

### estimated is disc u ssed in Section 3.2.4.1 and 

### provided in Appendix Ill. Typically , this eval uation in dicates 

### a clear predom.ina.uce of either rural or wban land use. The HHRAP specifies tlult the predominant category be selected in 

### air modeling settings . However, lhe evaluation of l and use in the Onyx risk asses sment area was just slightly more rur'81 than urban at 

### a total of 

### 50.05 % of the total. Representatives 

### from Illinois EPA and U.S. 

### EPA Region 

### 5 indicated that their determination of 

### land use classification 

### had favored 

### wban, rather than rural. Onyx used both rural Ulld urban settings 

### in two complete sets of JSCST3 air modelin g runs . In the interes t of developing the most si te- s pecific 

### estima te of

### risk and hazard 

### fpr 

### this assessment area, the average air modeling output values for lhe 

### two sets ofrum were utilized in the estimation of risk 

### and hazard. 4

### • The On yx R is k As sessment Protoco l stated that the average annual precipitati on for the years 1 9 88 through 19 92 was 

### 88 . 7 em/yr. B ecause 1985 au d 1987· 1 990 mereorologtcal data were u sed in the air 

### modeling, the ave rag e precipitation of 99.94 crn/yr for 1 98 5 and 1987-1990 wa s more app rop nate and wa s used in the assessmen t . • Air modeling ou tp ut parameters have been select ed 

### based on HlfRAP guidance. In the pre vi ous version of this repo rt, a maximum exposed residen t was located 

### based on the specific resident living ncar the fac il ity receiv in g maximum impact from emissions . The selecti o n of air modeling output parameter values for this revision is 

### described in detail in Section 3.5 of this repon . • The Southern Illinois fishing Map Guide in dicates that the surface area of the Frank Holten Main L ake is 39 2,545 m l 

### and the surface area of Frank B.olten Lake 113 is 323,748 

### m 2 • 

### The combined water surface area is 716,29 3 m 2 • 

### This value was confirmed using 3-D TopoQuads and was used in this risk as sess ment . A map s howing th e lake area and lake watershed orca is included as Figure 4-4 in Sectio n 4.4. • The water body and elevation data provided 

### by the 

### DeLonnos 3-D TopoQuads program 

### were used to 

### delineate the appropriate watershed area for the 

### lakes at Frank Ho lten State Park and the water bodies that 

### feed it. Figure 4-4 

### shows the lakes and 

### three sub-nrcas that contribute to 

### tbe watershed area, including the rnain lake, lake #3, and tbe immediate portion of the Harding Ditch feeding lake 113. Their respective areas are 3.25, 1.95, and 3.07 k:n { The total watershed area is the surn of these areas minus the lake surface water areas. As shown on the re fer enced map , the total area is 7,5 50 , 000 m 2 • This 

### value was used in the 

### risk: assessment. • To detennine the percent of the watershed area that is 

### impervious to 

### runofi, the watershed area delin eated using 3·D TopoQoads was overlaid on NCL D land use data. The resulting graphic was analyzed 

### using MatbCAD to quantify the land usage inside th e watershed area. Each 

### land use category was al!Si gned an estimated pereenr im pervious value. A weighted average was calculated to determine the overall pereent impervious to 

### runoff . For the Frank H olter.\ State Park watershed area, the percent 

### impervious to runoff W1L\ 

### detennined to be 3 1 %. Appendix ill 

### shows this calculation. Thus, the impervious watershed area receiving depos itio n in t . his risk assessment is 2,340,500 m 2

ns is highly dependettt on the constiniCllt itself. For example , the HHRAP 

### explains that . metals 

### and low vo lati le orgruuc compounds gcoerally exist almost entirely as 

### particle pho s e emi&sions. Other organi C$ occur in 

### tile vapor phase, etlber strictly as vapors, or with

### are condensed onto the surface of part ic ul ates are said to exist as particle-bound vapo r . As one w o uld expect , these various phases aro modeled differently, and req uire diff erent types of infonnati o n regarding the parti c le s. The difference in modeling of these phases prevents s intultaneous model ing of 

### all phases in

### particle s i ze , in combination with particle de nsity , is a key de terminant in tb e settling ve l o city of th e particle. Th e l arger particles w ill ha ve u gret uer settling ve l oc ity than the sma ller particles. Consequently , 

### !u rger particles will also deposit much closer to th e stack . This is easy to deduce; the laiger parti cl e s are usually heav i er, and i t is harder to mamtain them in the a i r flow. Alternatively , smaller particles ar8

### This will resolt in depo sition of smaller particles further from the stack. Similarly, f or Wt!t depOsition, the larger parti cles are more likely to be removed by falling
