Mike,

You are correct.

The CKD removed 

### from 

### kiln 1at Speed isthe same as theAPCD Dust Returned to 

### kiln

## L APCD dust 

### from 

### kiln 1 isstored ina bin and used to manufacture masonry cements. lf more APCD 

### dust is generated than can be usedfor finished 

### cement,the dust is returned to kiln 1. A separate 

### feedsystem is used to return APCD dust 

### to kíln 1. It is not mixed 

### with the

### feed produced inthe in-line mill producing kiln feed

### for both kilns. NoAPCD 

### dust is returned 

### to kiln 2. Mercury is 

### removed and returned 

### to kiln 1with APCD dust. 

### This represents 

### an internal recirculating stream rather than a raw material input. 

### That is

### the reason that only 

### cKD removed appears in

### the kiln 1 mass balance.

The distribution of 30 daily composite samples of APCD dust returned to 

### kiln 1 (also CKD removed) ranged 

### îrom 79.2 ppb

### to 1

### 99.9. Either 

### a normal or a log-normal distribution adequately describes these data. Using a normal 

### distribution,the mean value 

### was 124.g ppb. The arithmetic 

### average is

### also 124.9, The standard deviation is2S.4 ppb. For mass balance purposes, 

### we have 

### selected 124.9 ppb. The mean isestimated to 

### be 122.5 ifa log-normal fit ofthe data is used.

Laney,



### At Speed 

### kiln 1 produces all of

### the material called "CKD Removed". Kiln

### 2 produces a much smaller amount 

### of "CKD" that is called "Bypass Dusf'. 

### They are not the same 

### material. The bypass system at Speed

### was installed during 

### 2006. That isthe reason the mass of 

### CKD (Bypass dust) at Speed is reported to be 0

### tons in

### 2006. Samples of bypass dust from Speed kiln 2 are being 

### generated in

### 2007 andwill need 

### to include this material infuture mass balance calculations.



### All of the feed at Speed is produced inone in-line mill associated 

### with kiln 2. 

### The raw mill

### for kiln 

### 2 is designed to produce thefeed

### for bolh kilns 1 and 2. The amount 

### of mercury 

### from raw material 

### components, such asflyash, is apportioned to 

### each kiln based on the 

### totalfeedtothe kilns.



### At Logansport both

### the LWDF and the coke were samples and analyzed separately. The 

### coke samples 

### from 

### kiln 1contained an average of 3.0 ppb 

### mercury. Coke samples 

### for kiln

### 2 averaged 3.3 ppb 

### mercury. These values 

### were estimated from the censored distribution statistics fitto a normal variate for the values above 5 ppb, recognizing the total number of samples collected.

LWDF 

### at Logansport during the sampling period 

### in2007 contained 341 ppb mercury. 

### The analytical 

### resultsfor2007 samples 

### were applied tothe mass throughput 

### for 2006.



### APCD Dust Returned at Logansport is 

### materialcollected inthe ESPsthat is "promptly" returned to

### the kilns after a

### very short duration in a holding 

### bin. lt is notthe same material as 

### the Reclaimed 

### CKD. Reclaimed CKD is dust that has been placed in an 

### on-site landfill at a previous time that is now being reclaimed as a raw material component. One reason 

### that Reclaimed 

### CKD is used at Logansport isto add potassium and sodium to

### the mix

### for cement strength.To clarify 

### these results, Ihave attached aworksheet that illustrates the mass balance calculations. Only the Speed 

### and Logansport mass balance data have been provided, although we do have 

### these data for all of

### the Essroc

### kilns. lnthe case of Speed, there ís no practical way to sample the feed to

### the in-line mill because the "chunks" of raw materials are extremely 

### heterogeneous. The expected concentration ofthe

### feedtothe raw mill has been estimated to 

### be 19.6 ppb based on an input balance 

### withthe sum of 

### raw material 

### components. At Logansport, boththe raw components and the feed to 

### the kilnwere 

### sampled. The difference between the sum of raw components and the kiln feed mercury 

### was 7.5 % during the sampling program.

Please feel free to call me 

### at 610 837 3336 to discuss anyfurther concerns or clarifications. Iwould enjoy meeting with you and Steve inthe nearfuture to review findings and to explain how values below 

### detectionthresholds (censored values) can be correctly treated with statistical techniques. You should also be aware that a number of mercury distributions proved to be log-normal rather than normally distributed.

### I agree that aconference 

### callwould be good. Does 

### Friday 

### at I

### l:00 suityour schedule?



### In answer 

### toyour 

### first question about 

### "CKD Removed" and 

### "CKD Returned", there are differences at each 

### plant that need 

### to be 

### explained. When we have the rest

### of the mercury data Essroc 

### will provideyou 

### with mass balance 

### calculations that

### will make clear the amounts and concentrations 

### of mercury entering and 

### leaving the 

### kilns.

I'm sure that 

### you can appreciate that Essroc moved 

### quickly to begin 

### sampling Names selected are 

### in some cases 

### not as clear as

### wewould like, but sample bottles were sent and chain 

### of custody worksheets prepared using the names

### initially selected.We have reached a

### point where 

### changing some sample names is appropriate to 

### clarify for the agencywhat these samples represent, 

### Thank

### youfor raising these issues 

### now, sothat we can make these changes 

### to 

### limit confusion in the future.



### I have

### provided a

### brief description for each 

### of the plants that

### you mentioned.

Bessemer

# - Both 

### kilns control particulate matter 

### (PM) using electrostatic 

### precipitators (ESPs). Dust 

### fi'omthe

### first and sometimes the second

### field is conveyed to a

### binfor temporary 

### storageThis is

### CKD Returned. 

### At Bessemer, 

### CKD retumed contains the larger size

### fraction. At Bessemer 

### CKD returned is 

### blown 

### directly into the 

### burning zone 

### like coal 

### dust.This is

### called insufflation and is a requirernent 

### of the Bessemer

### air 

### permitto control nitrogen oxide emissions. 

### Kilns that 

### insufflate 

### CKD may be a separate category 

### for 

### MACT purposes. The 

### CKD removed at Bessemer comes 

### from the last 

### fields 

### of the EPS. 

### This represents the smallest dust 

### fraction. The 

### CKD returned is not a

### raw material component. The amount 

### of dust 

### recirculatingfrom insufflation to recapture 

### inthe

### first fields 

### of the ESP is

### difficult to determine. There is 

### no system 

### to

### directly measure the 

### insufflated dust soestimates 

### of returned dust must be made 

### indirectly. The 

### mercury 

### In CKD returned hasalready been counted 

### in the mass balance as 

### mercury led 

### into the

### kiln with 

### slurry. Double counting the 

### mercury In 

### CKD returned 

### would result in a mass balance 

### erÏor.

Logansport - 

### PM emissions are 

### currently controlled using an ESP at Logansport 

### but a

### fabric 

### filter is under 

### construction. CKD removed comes

### from the last 

### fields 

### of the ESP, as 

### it does at Bessemer.

### The

### CKD retumed

### from the 

### first fields isfed 

### directly into the 

### kilns using a

### vortex feeder separate from

the

### slurry. As at Bessemer, 

### it is

### difficult to measure the 

### CKD retumed. The 

### mercury hasalready been counted 

### through analysis 

### of the 

### slurry 

### feed. Recirculating mercury in 

### CKD returned to the 

### kiln is not a feed component.

Nazareth -

### No 

### CKD is 

### removed

### from the

### kiln at the Nazareth 

### plant. In fact, 

### it is unclear that there is any 

### material that can 

### properly be 

### called

### CKD that is generated at 

### Nazareth. Raw materials ground 

### in the Loesche 

### (raw) 

### mill are conveyed using 

### hot stack gases to 

### dry the

### feed. The feed

### from the 

### raw

### mill adsorbs 

### mercury 

### from the stack gases. The 

### raw

### mill discharge is 

### blown pneumatically into the 

### homogenizing silo binswhere 

### it is 

### mixed 

### with other materials. 

### The other 

### materials include the dust 

### collected in the baghouse 

### controlling PM emissions 

### from the Loesche 

## mill. This material is

### collected in hoppers under the baghouse and conveyed 

### by screw conveyors and enclosed elevators 

### into the 

### homogenizing

### silo.A second baghouse 

### controls PM emissions 

### from a

### kiln exhaust stream that does 

### not passthrough the Loesche

## mill. Dust 

### collected inthis fabric 

### filter isalso conveyed 

### tothe 

### homogenizing 

### silo using screw conveyors and 

### elevators The 

### materialfrom the 

### homogenizing silo,containing 

### all of the materials described above iscalled 

### kiln feed and entrees the 

### kiln

near thetop 

### of The preheater 

### tower. Mercuryfrom stack gases condenses onto the smallest 

### particles in the 

### kiln feed 

### recirculating and

### accumulating in the dust 

### from the

### two baghouses as

### well asthe 

### raw 

### mill discharge. There is a

### significant increase 

### in mercury emissions when the Loesche

### mill istaken out

## of service. This 

### typically occurs 

### for about 8 hours every ten daysto 

### perform maintenance on the 

### mill. There is no 

### regular schedule 

### of 

### milloutages. The 

### materialcollected in the

### fabric 

### filters goes 

### directly to the 

### homogenizing 

### silo. There is no

### wayto measure the amount 

### ofthis 

### materialrecirculatingwithin the 

### system. As in the case

### of Bessemer and Logansport, the baghouse dusts are not 

### raw material 

### components. Counting the 

### mercury recirculating inthis fabric 

### filter dusts 

### would be double 

### counting the 

### lllercury. Essroc

### will changethe name 

### fromCKD returned to Baghouse dust

### to 

### limit confusion onthis point. 

### A separate tab 

### for baghouse dust returned as feed

### will be createdto 

### clarify that 

### this material should not be named 

### "CKD retumed".

San Juan -The 

### kiln system at SanJuan is

### similar to Nazareth 

### with no 

### CKD removed 

### from the 

### Kiln and 

### fabricfilter dust 

### returnedtothe 

### homogenizing silo where 

### it is 

### mixed 

### with the 

### material discharged 

### from the Loesche 

### (raw) 

## mill. The 

### raw

## mill adsorbs 

### mercury from stack Gases and includes 

### recirculating 

### mercury. The baghouse dust alsocontains adsorbed mercury. These are 

### not raw material components and 

### including them as 

### raw materials 

### would double count 

### Mercury entering the

## kiln. As in the example 

### of Nazareth, 

### "raw 

### mill discharge" is a more 

### Appropriate term than 

### raw 

### mill feed. Thetwo components entering the 

### raw

### mill are limestone 

### And 

### mill scale.We 

### will remove 

### raw 

### mill discharge 

### from the 

### raw material component(RMC) tab. 

### The data is 

### duplicated in thetab named 

### "In Ln RM Feed" and should better be named 

### "ln Ln RM 

### Dischg". These changes

### will be made and an 

### improved worksheet sent on 

### Thursday in Preparation 

### for the conference 

### call on Friday.

Speed - Speed 

### is

### similar to Nazareth and San Juan, except that some 

### CKD is removed 

### fi'om 

### kiln 

### I and a 

### single Loesche 

### mill is used to prepare 

### kiln feed

### for both

### kiln 

## I and 

### kiln

### 2. The dust 

### collected inthe 

### kihi I baghouse istransferred 

### to a

### temporary storage 

### bin. This dust is used to manufacture masonry cements. Some

### of this dust is 

### sold

### directly to 

### customers. 

### Any

### kiln 

## I fabric 

### filter dustthat is 

### not usedto make masonry cement 

### orsold

### directly is returned to 

### kiln 

## I in asystem separate 

### from the 

### kiln 1 Loesche 

### mill feed

### system. The

### CKD removed 

### (sold

### directly or as masonry cements) isthe same as

### CKD returned at 

### Speed. The amount 

### of CKD removed 

### or sold is accurately 

### known because these materials are weighed. 

### However, the 

### recirculating 

### CKD retumed is not measured and is 

### not a

### raw material component. 

### Including the 

### mercury 

### from CKD retumed would result in a mass balance 

### error because the 

### mercury in

### this material hasalready been counted 

### in the feed 

### components. Changes to the Speed 

### raw

### mill discharge

and 

### RMC information that 

### duplicate these data

### will be made to 

### clarify the mass balance calculations.



### In short, 

### materialscollected in the

### fabricfilters and ESPs are returned to the 

### kilns in 

### Different Ways 

### including insufflation, vortex feeders, 

### mixing in a 

### homogenizing silo and a separate 

### kiln feed stream 

### When

### CKD is 

### returned

### it is 

### not a 

### raw material component and

### Treating 

### it as a 

### raw material would result 

### in double counting 

### of mercury in recirculating 

### Materials. 

### It is not part 

### of the 

### slurry at Bessemer or 

### Logansport and

### it is 

### not part 

### of the 

### Raw

### mill discharge at 

### Nazaretb San Juan 

### or Speed. 

### It is returned as described above.

We agree that 

### raw 

### mill feed should 

### not be equated 

### with raw

### mill discharge.To 

### clarify this Point, we

### will create atab 

### for raw 

### mill discharge and delete the

### duplicated data 

### from the Raw 

### material components tab.



### At Nazareth 

### what is fed 

### to the 

### kiln is a

### combination of raw

### mill discharge that has absorbed 

### mercury 

### from stack gases 

### plus dust 

### from 

### twofabric 

### filters that have collected dustthat hasalso adsorbed mercury 

### from stack gases and 

### recirculated this mercury increasing the mercury 

### concentration in the 

### recirculating 

### materials. The 

### raw material components are analyzed 

### individually including limestong flyash, bottom ash, 

### alumina, iron, clay, and 

### CKD landfilled and subsequently reclaimed as a ra'w

### material. For

### wet kilns 

### with indirect raw 

### mills it is possible 

### to analyzethe

### sluny in addition to the 

### raw material components to compare the 

### Mercury in each component 

### with the 

### mercury in the 

### kiln feed. 

### In the case

### of preheater 

### kilns, where 

### mercury in stack gases isadsorbed 

### onto feed 

### materials inthe Loesche 

### mill and the dust collected 

### in the ESP 

### or 

### fabricfilter, much 

### of the 

### mercury recirculates 

### within the 

### kiln and 

### Must not be double counted âs 

### mercury entering the

### kiln with feed.



### I hope that 

### this clarifìes the 

### mercury mass balance issues

### for these

### preliminary data 

### As 

### I said, Essroc

### will provide you

### with a

### complete mass balance estimate 

### for mercury for each 

### Of our 

### kilns when we are prepared to 

### provide the rest

### of the 

### mercury analyses.

### Subject Questions onthe ESSROC Data submittal

Dear Hector:

We have some 

### additional question onyour data 

### submittal. Once you have had time to lookover the questions, 

### why don't 

### we set up a call,

### just incase more questions come upfrom your answers. 

## -You 

## report Hg

## content 

## of "CKD 

### removed" 

## and "CKD 

## returned. 

## " I assume 

### CKD

## returned is what 

## is put back 

## into kiLn. How

## is it retuned? ft is not 

## reported as 

## a "raw 

## material componenttr 

## for any 

## of the kil-nsthat return it
(

### Bessemer, 

## Logansport, 

## Nazareth, San

## Juan, Speed). So 

## is it part of the slurry at Bessemer 

## and Logansport? And

## for the dry kilns, is the CKD

## part of the 

## "raw 

## mill discharge" 

## at Nazareth and 

## Speed? 

## Or 

## is it returned by another method? 

## -In the "Inline raw 

## mill feed" tabJ-e, 

## the reported Hg

## for Nazareth and 

### Speed 

## is the same

## as "Raw 

## Mill Discharge" 

## in the 2 tabLes

## of "Raw 

## MateriaL Components"

## for Nazareth and Speed.

## This is a litt.le confusj-ng 

## to me 

## because 

## I would 

## not have equated raw 

## mill feed 

## with raw 

## miLl discharge 

## -In the t'Raw 

## Material Components" 

## tabl-es 

## for Nazareth and Speed, 

## what

## is being 

## fed to the kilns: raw 

## mill discharge 

## only, or raw 

## mill discharge, 

## limestone, clay, iron, etc.



## - Similar to the previous 

## question, the Hg

## content 

## of slurry in the "Raw 

## Material Components"

## tabLes

## for Bessemer, 

## Logansport, and 

## Martinsburg 

## is the same 

## as

## that in the "indirect mill feed"table. Ílhat is the total- Hg 

## going 

## into the wet 

## kilns - the Hg 

## in the slurry only or the Hg 

## reported 

## for the slurry, limestone, 

## mill scale, etc.?

"Anderson, William" <wcanderson@stl-inc.com>, "YBAN EZ Hector" <H ECTOR.YBAN EZ@essroc.com> Essroc Sampling andAnalysis - EPA request for mercury and TOC information

Keith,

Essroc 

### will begin sampling next Monday, May

### 21,2007 to comply with

### the May 8 letter from Peter Tsirigotis. I have been 

### assigned responsibility for ensuring the success of the Essroc sampling and analysis program. Hector 

### Ybanez asked 

### that Iprepare 

### this notetoyou clarifying issues that may have the potential to cause concerns.

I have 

### attached an email distributed yesterday 

### to plant environmental engineers and quality control 

### chemists concerning sampling requirements. Please review that document 

### and let us know ifyou have a different view on any of

### the issues raised for 

### sample collection.



### The methods 

### referenced in Mr. 

### Tsirigotis' letter are essentially "SWB46" 

### methods. Essroc has retained Severen 

### Trent Laboratories (STL) to provide guidance and analytical capabilities to accomplish the sampling and analysis 

### required. Dr.William 

### Anderson of STL 

### and Ihave discussed 

### a number 

### of issues raised 

### on review ofthe methods to be applied to determine the mercury and Total Organic 

### Carbon (TOC) 

### concentration inthe thousands 

### of samples that

### will be

### taken. Dr.

### Anderson has pointed out that SWB46 methods are guidelines to which 

### professionaljudgment must be applied to produce practical, 

### accurate 

### results. This is explained invarious chapters of SWB46

### where it becomes clear that the quality of

### the results isthe responsibility ofthe analytical laboratories, even when difficulties arise inthe application of the SW846 methods.



### Essroc intends to use a direct mercury 

### analysis method that is inaccord 

### with Method 

### 7473 and capable of detecting concentrations 

### as low as 20 parts 

### per billion 

### (ppb). Depending on results, some samples 

### willalso be analyzed using HFtotal digestion procedures to 

### compare results with the 

### direct mercury 

### analysis. The 

### laboratory Essroc has selected willfollow the quality control guidelines for duplicate, spiked and calibration samples
as 

### specified in

### the 

### method. Analytical reports 

### will include thetimethe samples 

### were received and 

### analyzed inaddition to

### sample identification 

### parameters. The samples will be retained on site at the analytical laboratory through at least September, 2007 so that 

### confirmatory analyses can be provided 

### as 

### needed. Since the all ofthe samples have been exposed to ambient or hightemperatures,there 

### will be no need 

### to refrigerate any

ofthe

### samples. ln addition, the usual 

### 28 day holding time 

### for mercury samples will not

### apply. No change inthe mercury concentrations for these samples is

### expected under 

### long{erm (six month or greater) 

### storage. Given the huge number of samples, the nature of

### the samples and the ability to confirm 

### previous results 

### with reanalysis and comparative analytical methods, the guidelines for refrigeration and holding time shall not apply.

Analysis for TOC 

### will be

### conducted usíngthe Lloyd Kahn modification of Methods 9060 and 

### 9060a. One ofthe laboratories selected to do these analyses employs a Shimadzu SSM-50004 TOC 

### analyzer. We understand that phosphoric acid is substituted 

### for hydrochloric or sulfuric acids where 

### samples high incarbonates are to be 

### analyzed. As explained above, no refrigeration or holding times are required to provide accurate analyses ofthese 

### samples. For some materials, TOC results will be lower than the quantification limit

### of 500 ppm. Itwould be unreasonable to run hundreds of "non-detect" samples, when 

### this information 

### can be obtained by analyzing composite samples plus randomly 

### selected daily 

### samples. lnorder to determine 

### which daily samples need to be analyzed for TOC, the laboratory will prepare composite samples representing two 

### weekor longer intervals from the daíly 

### composite 

### samples. lfall of the long-term composite samples and selected daily composite samples of

### a particular material (for 

### example, Bessemer 

### Kiln 1slurry feed) are below 500 ppm, no further analyses for TOC for 

### that material 

### will be 

### conducted. The TOC concentration will be reported
as less

### than 500 

### ppm. For materials which demonstrate the presence of measurable levels of TOC, multiple analyses of daily composite samples will be run to determine the average and variability ofTOC 

### results. The requirement for quadruplicate analyses specified in 

### methods 9060 and 9060a 

### will not 

### apply. Rather, 

### the laboratory analyst will determine 

### the number of additional samples to be analyzed based on the results 

### for each 

### sample analyzed.

Ifeel sure you will appreciate 

### the need to focus resources onthe most important questions aswe undertake this

### voluminous sampling and analysis program.

lfyou have any 

### questions or comments, please call me at 610 837 3336 or send an email.

## Slj,| Su*nle Preparation 

### for Shipment 

### toAnalytical Laboratories

Folks,

As

### we agreed inthe 

### conference call 

### last Friday, the samples to be taken to comply with 

### the EPA Section 114 letter 

### that Essroc received last

### week need to be collected 

### with rigorous quality assurance protocols. Representatives of Severen 

### Trent Laboratories (STL) have assisted us by preparing master sample logs, daily sample collection sheets and request for analysis/chain of custody forms.

All 

### samples sent to

### the laboratories must be homogeneous dry 

### powder. The laboratories will remove a 

### sample (<1 gram) 

### from each 

### container. The sample you send must be a sample from which a representative aliquot can be removed 

### with no 

### further preparation. Forsamples offuel taken from the burner pipe, CKD and ground feed to sent to

### the kiln, fine dry powders are collected directly at the sampling 

### locations. For clinker 

### samples, please grind the samples finer than 

### -200 mesh before preparing split 

### samples. For slurry from 

### wet-process kilns, please drythe samples as

### you normally do and retain


### excess dried 

### feed material to prepare 

### your daily composite 

### samples. For raw material components, minimal 

### drying is 

### recommended, so long as a homogeneous "dry" powder is produced for sample splitting. A 

### clay or 

### other material 

### with highwater affinity can be dried at 105 C as necessary to produce a dry 

### powder. Excessive 

### drying must be avoided.

Sample 

### splitting into

### thirds is

### accomplished'by thoroughly shaking the container of dry powder to achieve

a 

### homogeneous 

### mixture. Remove approximately 200 grams of material from the thoroughly-shaken composite 

### sample mixture and place iton a clean sheet of 

### paper. Carefully divide the pile of dry powderinto 

### "sixths" using a clean spatula to divide 

### the

### pile. Remove two "opposite" sixths into one of the sample



### containersto prepare the first split 

### sample. The two remaining "opposite sixths" to prepare the second split 

### sample. The remaining sample is placed into athird sample 

### container. One of the samples will be analyzed 

### for mercury, another for TOC and the third will be archived for repeat or subsequent analysis.



### The sample 

### containers shipped from STL 

### will be packaged with five 

### cases (24 count) per shipping box. 

### The packaging 

### materials must be saved so that the samples can be shipped tothe laboratories inthe

same shipping 

### materials. This procedure 

### will minimize 

### breakage. Collect mercury samples in one set

### of sample 

### cases until 5

### cases have been 

### accumulated. A plant collecting 10 mercury samples per daywill fill the 

### sampleshippíng 

### box in 12 daysof sampling. (10 

### samples per day

### X 12 days of sampling 

### = 120 samples = 5cases X24 samples per 

### case). There is

no need to refrigerate 

### samples. The materials used to manufacture cement are stored at ambient 

### temperatures and exposed to high

### temperatures in

### the pyroprocess. Mercury present infeed to the raw mills

### will be stable as complex mercury minerals.

Since the only constituents to be measured are mercury andTOC, you may use grinding equipment which contains 

### chromium metal to prepare these 

### samples. The amount of chromium contamination possible 

### from chromium grinding equipment in

### this instance isacceptably low.

Please complete the daily sample collection logthat describes thetimewhen each component of the 

### composite sample 

### was

### collected. The initials ofthe individual should be entered in addition to thetime 

### whenthe sample 

### was collected. At least three samples are needed for each daily composite sample, unless an equipment 

### failure prevents collection of

### a "shift" 

### sample. lnthe case where equipment outages 

### result in a "short 

### sample" it is bestto start preparation of another complete composite 

### sample. lf a "short" 

### compositesample is submitted for 

### analysis, it is

### essentialthat notes on the sample collection sheet describe 

### the reason 

### for collecting that sample.



### When a shipment of

### samples has been 

### collected, split and packaged for delivery tothe laboratories, a request for Analysis/Chain of Custody sheet 

### will need

### to be prepared and sentwith the samples.

All 

### mercury analyses 

### forthe first round of samples will be completed by: G &
