CONTACT SUMMARY 

Notes prepared by Wanita Dunston. 

As per attachment (August 2 fax from Bob Kinman to Wanita Dunston), the following 

questions/comments were discussed during a telephone conversation: 

• MAY ANY OF THE INFORMATION DISCLOSED IN THE ATTACHMENT BE 

REFERRED TO AS "CONFIDENTIAL BUSINESS INFORMATION"? (MR 

KINMAN WAS INFORMED THAT THE CONTENTS OF THIS CONTACT 

REPORT, AS WELL AS THE ATTACHMENT WILL BE INCLUDED INTHE 

DOCKET). 

t Mr. Kinman cited the following as "confidential business information" (CBI): A. 1, the 

response to question 1, regarding their specific process is CBI because h is unique, it is . , _ 

their primary process, and they are the only one who does this on pipework; tho pjpe sUeiTC^* sT 

given in Ai>i snd AIO, which givea hiferifiation about the corrosion rtsinaUc<! ufliii pipcw TM^ ?V*r 

Per conversation with Mr. Kinman, the attachment has been converted into a non-CBI CAtwft&Hfc 

form, by darkening out all confidential information. A9 and AIO are no longer considered w / fob 

as "confidential" and will be included in the non-CBI version for inelusion in the docket. ]C|\r*£*> 

The non-CBI form is attached, for his approval, along with this contact report. The CBI JI Hl L 

version is on file in the OAQPS CBI office. '•J,** * 

• COULD I HAVE THE NAME AND NUMBER OF THE STATE PERMITTING 

AGENCY WHERE YOUR EMISSION TEST REPORT WAS SENT? (I WOULD 

LIKE A COPY OF THE REPORT). The person on site was Glen Castleberry with Tulsa 

City/County Health Department, his phone number is (918) 744-1000. Air Quality 

Division Director for the county agency is Ray Bishop. The testing was done April 1992. 

• IN Al., IT IS STATED THAT CAPTURE EFFICIENCY HAD NEVER BEEN 

CALCULATED. WOULDN'T IT BE 100% SINCE THERE IS A SINGLE EXHAUST 

DUCTED TO THE CATALYTIC INCINERATOR? IS IT "HARD PIPED*? No, the

capture efficiency is unique. We went back in and redesigned the hoods. They were 

sealed shut, and to do capture effidency on the whole process would be too expensive. 

The machine sits in a building of approximately 96000 ft3. The State (an EPA region 6) 

waived the responsibility of calculating capture efficiency. WOULD IT BE 100%? Bob 

replied that "It could be." 

IN A3., IT IS STATED THAT THE "VOLUMETRIC FLOW RATE IS VARIABLE..." 

WE WOULD LIKE TO KNOW THE MAXIMUM, MINIMUM, AND AVERAGE 

NUMBER OF LINES VENTED AT A TIME, AND THE CORRESPONDING 

VOLUMETRIC FLOW RATES. Epoxy resin grade has no listed HAPs in tha resin itself; 

it exhausts to atmosphere. A manual switch opens so that the operator can switch exhaust 

to oxidizer or to the atmosphere. Epoxy emissions could diminish the catalysts in the 

catalyst bed. Vinyl ester is vented to the incinerator for the styrene emissions. 

IT IS STATED THAT THERE ARE 16 CENTRIFUGAL CASTING MACHINES; 

HOW MANY BMC UNES EXIST AT YOUR PLANT? There are 16 machines, an 

average of 6 are vented to the incmerator. For BMC, there is one line that uses strictly 

vinyl ester for compression molding, and this one is vented to the incinerator at all times, 

The other line is strictly for epoxy resins, so there is & total of 2 BMC lines. 

IN A6., THE INLET AND OUTLET CONCENTRATIONS OF STYRENE ARJE 

GIVEN. HOW MANY CASTING MACHINES WERE VENTED (TO OBTAIN 

THESE VALUES) AND WHAT IS THE CORRESPONDING VOLUMETRIC FLOW 

RATE? The average inlet concentration^ SO ascfm, the average outlet concentration^ 

5600 ascfm, and the corresponding volumetric flow rate is (WHAT IS THE 

CORRESPONDING VOLUMETRIC FLOW RATE?) HOW MANY LINES ARE 

BEING VENTED TO THE INCINERATOR FOR THIS TEST? All 16 casting machines 

and one BMC line are being vented for this test. The casting machines account for 75% 

ofthe company's emissions. 

IN A7., THE STATEMENT IS MADE "UNCLEAR AS TO WHAT IS MEANT BY 

APPLICATION? THE APPLICATION DURING THE CENTRIFUGAL CASTING 

PROCESS CONSIST OF REINFORCEMENTS AND RESIN BEING DEPOSITED 

AGAINST THE INSIDE SURFACE OF A ROTATING MOLD, AND CENTRIFUGAL 

FORCE HOLDS THE MATERIALS IN PLACE UNTIL THE PART IS CURED. IN 

LIGHT OF THIS DEFINITION, THE ANSWER TO MY QUESTION ABOUT 

WHETHER OR NOT THE APPLICATION IS CONTROLLED WOULD BE "YES". 

The run time is 60 minutes for one pipe and it is totally cured within the mold. 

WHAT QUANTITY OF RESIN GOES TO EACH LINE (i.e., WHAT % OF THE BMC 

PROCESS IS CONTROLLED)? It varies. For the 1 inch pipe size, an average of 5 lbs of 

resin is used; for the 14 inch pipe, an average of 74 lbs of resin is used; the quantity of 

resin used depends on the length ofthe pipe and the wall thickness. A brochure will be 

sent to Wanita, giving infonnation about corrosion resistance, resin content, weights, etc.

4. In the Introduction to Composites Reference Handbook, Third Edition, centrifbgal casting 

is defined as a production technique for fabricating cylindrical composites, such as pipe, in which 

composite material is positioned inside a hollow mandrel designed to be heated and rotated as 

resin is cured. The outside surface ofthe pan is the "finished" surface. 

Infonnation is accurate:
