Summary of personnel and task monitorings------------------------------------ --V. Carson
Results of the personnel monitorings (6 hr.) for process operations were 100$ under 0.5 ppm of VCM.
Task monitorings (33 samples of 15 minutes each) were 97$< 5 ppm* High task monitorings were:
a. Taking T.S.---------------------------------------------------------- 23.4 ppm
b. Taking T.S.--------------
2.89
c. Blowdown of Small Poly --------------------------------- 2.12
d. Taking T.S.-------------------------------------------------------------- 1.77
The standards limit is 5 ppm.
Summary of work area monitorings------------------------------------------------------------- G. Wilson
Monitorings (one every 1.66 minutes) in our regulated building averaged 0.55 ppm of VC1 this month with 5*7$ of the readings exceeding 1 ppm of VCM, 0.9$ over 5 ppm and 0.05$ over 99 Ppm.
Process operators of our regulated building wore their masks as follows:
Ave.
Maximum
1st Floor
27.19 min/shift
201 min/shift
2nd Floor
30.03 "
"
161
3rd Floor
53.01 "
212
Four additional sensors have been installed to measure 2nd floor of 4l7, Bowen drier, control room, and the breathing air.
High exposure operations
L.A. Bennett
High exposure areas are:
a. Seal leaks (VC1 pumps)
times reported since 6/15 54
b. Sampling (large and small)
54
c. 3000 gallon stripper - venting
42
d. VCM charge bottle - venting
60
e. Small Poly - venting and evacuating
27
f. Blowing down sampling charge to stripper
47
g. 100 gallon stripper venting h. ALGCP
67 60 plus
Review of EPA VCM standard that issued on October 21, 1976 Standard reads as follows:
Section 6l.6o (b)-------This subpart does not apply to equipment used in research
and development if the reactor used to polymerize the vinyl chloride processed in the equipment has a capacity of no more than 0.19 m^ (50 gal.).

4. (Continued)
(c) Sections of this subpart other than 6l.64 (a)(l), (b), (c), and (d) do not apply to equipment used in research and development if the reactor used to polymerize the vinyl chloride processed in the equipment has a capacity of greater than 0.19 m^ (50 gal.) and no more than 4.07 m3 (1100 gal),
A waiver was requested on November 10, 1976 for a recovery unit in the VCM pilot plant. Time schedule to be as follows:
a. Purchase orders to start b. Initiation of construction c. Completion of construction d. Compliance to be achieved
2/0/77 7/0/77 2/01/78
5/01/78
5. Status of ^0 gallon stripper----------------------------------------------------------------------------- G. Wilson
Stripper (^0 gal.) for latexes and dispersion resins is being tested. Foam and dilution are problems. Stripper for suspension resins continues to operate satisfactorily
6. Status of two new 55 liter polymerizers------------------------------------------------------G. Wilson
P Polymerizers are on hand. Flush bottom valves are now being designed. Poly merizers should be operational in 2nd quarter of 1977*
7* Status of KV in VCM line from ALGCP-------------------- --------------------- --------------------- G. Wilson
Last Saturday, the KV was moved to near the pump house, where it can be tied into the ALGCP VCM recovery system.
8. VCM recovery system-----------------------------------------------------------------------------------------------G. Wilson
See (4) above.
9. Tall stack---------------------------------------------------------------------------------------------------------------- G. Wilson
Stack should be here by November 22, and up and operating in December. Then we will tie in the VC1 jets.
10. Breathing air---------------------------------------------------------------------------------------------------------- G. Wilson
Breathing air filter is operating satisfactorily. At first the air was by passing the filter media. This has been corrected.
Plan to extend lines to the Hydrin Area. Will also calculate the cost of a unit for building 422.
11. Air Masks------------------------------------------------------------------------------------------------------------------ J. Alten
Ran out of masks - twenty-five are on order. Maintenance men working full time in B/4l4 have masks as do process operators.
Safety department reported that all are taking good care of their masks.

12. Bottle polymerizers for B/4l4----------------------------------------------------------------------------- G. Wilson No information. Will check with Leeson.
13. S.O.P.'s for process building B/4l4 ------------------------------------------------------------------G. Wilson An S.O.P. for the dispersion latex stripper has been circulated for comments.
14. Masks in Control Room? ------------------------------------------------------------------------------------------- L. Bennett It was the consensus of the group that more data be obtained before we begin wearing masks in the control rooms of B/4l4.
