* There ^re 3 -buMnggC&mpoeite Structures* Plant 2, and Plant 3. Composite Structur ;s 

and Plsnt 2 used to belong to Hercules (who filled out the survey), hut were sold to 

Affiant Tecfcsyatems. Plant 3 stiUbelongs to Hercules. , . , ^ , !<•*,,.-£-,, 

* One of thefeetihipi ta/Composite Structures, is 2440: "cybnTwrfbotT^Pfo prepregs cr

motor noaies. CMs is a small flber structure v^nch is rigid, strong tnd lightweight), rhe 

pitdi is the "resin equivalent". The product is like a brick, which is machined into shajje 

denoted. 

DOES ANYONE ELSE DO THIS? Yes- HITCO <Colorado> was cited. WHAT 

STANDARDS COVER THIS? No standards cover this. Pitch k added to graphite i 

-within a dosed container. The scctaeraSor handles the resuming polycyclic organic 

emissions. The polycyclic organic emissiens -were -stzneted to be on th* order of 100J 

pounds per year. 

WHY IS AN INCINERATOR. BEING USED THERE Qt waa fitated tiiai emissions ncm 

the process were minimal)? Susan wa* unsure. Hercules volunteered to use the 

Incinerator. Jonathan mentioned that it was tiie "Best Avri!able<^^ijec^s

HOW ARE EMISSIONS CALCULATED? Fitch is weighed,!** it goes into ihs proc* 

and then again as H comes out of tbe process; a mass balance. 

DO THE FACIUTIES STILL USE THE SAME INCINERATOR? The same equipment 

ii used as when ell buildings belonged to Hercules and -when, survey was completed. 2440 

(which 1$ in Composite Structures) has 'tz ow* incinerator, «sd Plant 3 has its owe \ 

incinerator. i 

SOLVENT COATING IS VENTED TO AM TNCIKEaAIOR- The solvent coating 

process is done at ?iant 3, which is held by Hercuies.' Rich Aaiersoa is thd contio, pipie 

nxm3bsr(80! 2514686). 

i 

WHAT ABOUT 2343? At 2343, vacuum bagging is used so thai prepreg retfias shapL 

It cures in ?.n aatodsve. Aay emission* from the curing would be sent to th© vacuum j 

pump and then exhausted to the stnscspbere. Epcxy resin is the predominate raw material 

aad Susan presumed no emissions resuk frc-aa tbe curing of epcxv resin. Emissions from 

2343 result from ths use ofdsaning solvents, uswl for die jmandreh. Susan indicated thst 

they have moved away from many ofthe cleaning solvents listed on the survey. WHAT 

ABOUT HTS? 2343 and HTS are basically the sacra process, the sarce prepreg is us'ejd, 

however one is band layup and one is machine operated; tllfe difference is basically ra the 

application. 

IS THERE SOMEONE ELSE WHO DOES SIMILAR PROCESSES; IS 113ERE A 

TRADE ASSOCIATION THAT COULD BE CONTACTED? IS THIS AN 

AEROSPACE APPLICATION? Rohr was cited as a similar source, however nothing 

more than the name was known. Madeleine suggested tbat she would contact someone in 

the aerospace industry trade association. *i 

Hercules will be contacted tor information on Plant 3 (solvent coating emission point}, &ud 

analysis will be conducted to detennine if this facility will be in the reinforced plastic j 

composites source category.
