Keith,
Please confirm that EPAwill be sending an 'official'correspondence via US Mail for our records. Also, itwould be helpful to know the calendar date of 'nextTuesday'. Iam assuming it is not'this' Tuesday (February 1), but instead, you are referring to'next'Tuesday (February 8). Thanks, Gina

### Dear Gina: 

### As you probabJ-y

## are in the process 

## of finalizing the CISWI 

## rule. In order to do 

## a quick QA 

### check 

### on 

## our CISWI

## kil-n inventorj-es and 

## floor kilns, we

## are following up on 

## our initial data request by 

## coll-ecting some 

## additional data on 

## specifics of certain secondary fueLs 

### you 

### reported 

## using. Given 

## the short time frame, we

## are asking 

## for a 

### response 

## to the email by COB 

## nextTuesday. If you cannot 

## obtain a 

### complete response 

## bythat time frame, please send 

### us what 

### you can 

### by COB 

## next Tuesday. 

### The 

## information on CEMEX

## kiln fuets in our current data base 

## is shown 

### below: (Embedded 

### image moved

## to f 

### il-e

## z píc1.9264.9tf.)

We

## are requesting 

## this additional information to gain a better understanding 

## of the source and 

### nature 

## of the materials combusted. We 

### have

## the folJ-owing 

## additional questions on 

## tires, TDF' and used

## oils for the kilns shown 

### above 

## (the numbers

### Tires Please 

## providethe following information on 

## the tires combusted

### during 

## the emissions

## part of your response 

## to the ICR 

### noted 

## above. If you cannot quickJ-y 

### determine 

## that information for the 

## time periods 

## of the emissions 

## tests, we 

### would 

### ask

## that you provide 

## information on 

## the sources

## of tires in the last 30 days.
What 

## is the source 

## of the whol-e

## tires you 

### combust? Do

## they come

### from 

## tire piles or fandfill-s, or from an estabLished 

## tire management program? 

### An 'establ-ished 

## tire management 

### program' 

## is one

### which 

### harvests 

## tires from

## vehicles and 

### businesses, and

### then manages 

## the tires carefully so

## Specifical-Iy, where

## explain what you meant 

### by TDF, 

## i.e. are 

## tires, sorting the tires, and removing 

### and 

## wire from 

## the tires? Or have 

### other processing

## is, they must

### oftires inthe last 30 days.



### What isthe source 

### of thewhole tires you 

### combust? Do they come 

### from tire piles 

### or landfills, 

### or from an established 

### tire management program? 

### An'established tire management 

### program' is one 

### which harvests tires 

### from vehicles and businesses, and then manages the tires carefully so they are 

### not thrown away between 

### collection and eventual uso asfuel, 

### for example by use 

### of a

### tracking system.



### If you are receiving tires 

### from sources other than an established 

### tire 

### progran¡ do they undergo processing

### to produce a

### tire derived 

### fuel? Specifically, where

### you indicated 

### 'TDF' in

### your ICR response, please explainwhat you meant by

### TDF, i.e. are 

### you shredding

### or chipping thetires, 

### sorting thetires, and removing asignificant amount 

### of the metal and

### wire from the

### tires? Or have 

### other entities done this tyrpe 

### of processing 

### to produce the 

### TDF? 

### A Separate Ouestion Relating 

### to Use

### of Whole Tires as a Fuel 

### TDF

### Our understanding isthat kilns that use whole tires asafuel substitute rely on a certain grade

## of

tire. That is, they must be

### of a certain size and shape in 

### orderfor the handling system 

### to

### work. It has been suggested that tires that are removed 

### from long abandoned piles

### orfrom

### within landfills 

### would have 

### to be chipped/ground, 

### or at leastwashed 

### & drained 

### prior to use asfuel 

### for most 

### facilities in order 

### to maintain consistent size, shape 

### & cleanliness required by the

### tire conveying 

### systems. For this reason tires that have collected 

### water

### & debris/soil 

### or are deformed from being landfilled generally

### will not

### work in 

### kiln

### conveþg systems, and are 

### not used. Has this been

### your experience 

### with using tires as afi¡el?
