MEMORANDUM

TO: Jodi Howard, US EPA/OAQPS/SPPD/RCG

FROM: Eastern Research Group, Inc.

DATE: February 7, 2012

SUBJECT: Hazardous Air Pollutants in Stripped Resin for the Polyvin yl Chloride and

Copolymers (PVC) Source Category

ERG analyzed the updated and corrected database of stripped res in sampling data

submitted 1 by the Vinyl Institute with their public comments on the proposed rule to determine

which HAP, other than vinyl chloride, were reported consi stently as non-detects or below

detection limit by all facilities. This analysis was p erformed separately for suspension resin,

dispersion resin, suspension blending resin, and copolymer r esin.

Attachment A details, for each resin type, the total nu mber of data points reported for

each HAP (other than vinyl chloride) and the number of dat a points that were reported as nondetects or below detection limit.

Based on the analysis, Table 1 shows the nineteen HAP, ot her than vinyl chloride, that

were detected by at least one facility (value reported above the detection limit) for all fo ur resin

types.

Table 1. HAP Detected in Stripped Resin

2,2,4-Trimethylpentane Ethylidene Dichloride

2,4

- Dinitrophenol Formaldehyde

Acetaldehyde Hydroquinone

Acetophenone Methanol

Benzene Methyl Chloride

Bis(2-Ethylhexyl)Phthalate Toluene

Chloroform Vinyl Acetate

Cumene Vinylidene Chloride

Ethyl Chloride Xylenes (Mixed Isomers)

Ethylene Dichloride

Included as part of their public comment submission 2 , the Vinyl Institute included a list

of HAP that were analyzed by at least one facility but were not detected by any facilities. Those

HAP are listed in Table 2, The Vinyl Institute recommended t hat facilities test for the HAP listed

in Table 2 periodically or once a year.

1Table 2. HAP Identified by the Vinyl Institute that we re Tested for but not Detected by

any Facility

1,1,2,2 – Tetrachloroethane Hydroquinone a

1,3- Butadiene Methylene Chloride

Chlorobenzene n-Hexane

Chloroprene Phenol

Ethylbenzene Trichloroethane

Ethylene Glycol Vinyl Bromine

a Hydroquinone was detected.See Attachment A for
