WARNING

This Microsoft Excel workbook contains a compilation of emissions testing and resin sampling data received by US EPA in response to requirements under C AA section 114 of companies in the polyvinyl chloride (PVC) and copolymers source categor y. The information contained in this workbook are the data as received by EPA and as such, have n ot been standardized or otherwise reformatted (with certain limited exceptions). This workb ook is provided for informational purposes only and users are cautioned against performing analys es on the data and information
contained in this file.

OVERVIEW

US EPA issued a Clean Air Act (CAA) section 114 informat ion collection request for the polyvinyl chloride (PVC) and copolymers production source cat egory. The information collection request was mailed to companies on August 12, 2009. Responses to the emissions testing and resin sampling portion of the request were due t o US EPA on February, 28, 2010.

This workbook file contains a compilation of emissions t esting and resin sampling data received through June 21, 2010. Data received after that point will be reviewed, consolidated, and added

to future versions of the workbook. This workbook does not co ntain data or information received by US EPA from the required survey portion of th e request. Survey response information is contained in a separate database file.

There are eleven (11) worksheets within the workbook. Eac h worksheet contains consolidated data for all facilities that submitted data. Description s of each worksheet can be found below.

Worksheet Name Description COTHCCH4MonitoringData 30 days of CO-THC-CH 4 monitoring data for each facility. COTHCCEMS CEMS data submitted by facilities.

30DayProcess-Stripper 30 days of resin type, grade, production, and moisture data co llected at the stripping

unit.

30DayProcess-Dryer 30 days of resin type, grade, production, and moisture data co llected at the dryer

unit. 30DayProcess-Fuel 30 days of fuel data on an equipment basis. 30DayProcess-TO 30 days of process data collected from the thermal oxidation units. 30DayProcess-Scrubber 30 days of process data collected from scrubbers. 30DayProcess-Adsorber 30 days of process data collected from adsorbers. EmissionsTesting Results of emissions testing conducted at each facility. ResinSampling-Stripper HAP analysis of resin slurry sa mples collected prior to the dryer. ResinSampling-Dryer HAP analysis of resin collected a fter the dryer.07/16/2010 Page 2 of 3

WORKBOOK CREATION

The following is a brief outline of the steps taken in c reation of the workbook.

Data submitted to EPA in one or more of the data templa tes provided were compiled for all companies into a single master Excel workbook. Indivi dual data template files correspond to the
master workbook sheets as shown below:

Excel Data Template File Name Consolidated Data Worksheet Name PVC_30Day_Process_Data_rev20100222.xls 30DayProcess-Stripper 30DayProcess-Dryer 30DayProcess-Fuel 30DayProcess-TO 30DayProcess-Scrubber 30DayProcess-Adsorber PVC_CO_CEMS_Monitoring.xls COTHCCEMS PVC_CO-THC-CH4_Monitoring.xls COTHCCH4MonitoringData PVC_ResinSampling_Data.xls ResinSampling-Stripper ResinSampling-Dryer PVC_Testing-Emissions_Data.xls EmissionsTesting

Following compilation of the submitted data, QA/QC was pe rformed by cross-checking submitted data against the compiled worksheets. The QA/QC process resulted in the following
observations and revisions to the data:

o Blank records were removed.

o To the extent possible, identifiers such as Process Unit ID, Equipment ID, Resin Grade, etc. were standardized by including dashes to correspon d to the format requested by EPA.

o To the extent possible, reported resin types were standa rdized (Suspension, Dispersion, etc.).

o Numeric values reported as percentages were reformatted t o remove the percent symbol (%).

o Columns were added to incorporate additional information pro vided by facilities on templates.

o For test results below detection limits, facilities r eported results as “Non-Detect” (ND) or as the detection limit in brackets (e.g., [<0.10] ). No modification of any facility’s submitted format was made in the workbook wit h regards to detection

limits.

Concurrent with the process, resin, and emissions data compilation, CO/THC/CH 4 monitoring data submitted by each facility was combined into a single workbook. Since three facilities
submitted CO/THC/CH 4 monitoring templates with additional columns, the additio nal columns were added to each facility’s CO/THC/CH 4 monitoring data set (although they are null records). The data sets were then compiled into the format presen ted in the final workbook.07/16/2010 Page 3 of 3

One facility submitted hourly monitoring data which is not included in this version of the

combined data.

Three facilities submitted CO/THC continuous emissions monitoring system (CEMS) data. The three data sets were compiled into a single workbook si milar to the CO/THC/CH 4 data.

The final step in the master workbook creation was the combination of the process, emission, and resin sampling data with the CO/THC/CH 4 and CO/THC CEMS data.
