We determined that you used the original PVC survey forms (parts 1 and 2) to complete the data request instead of the 

revised forms that were posted on November 10, 2009. Please take a look at the changes from the original PVC survey 

forms to the revised forms and let me know if what you submitted reflected the changes on the revised forms.

Thanks.

Below is a summary of the revisions that were made to the survey forms.

Also attached:

1. The first set of forms that were posted:

SURVEYPart1_[Company]_[Facility]_[ProcessUnitID].xls

2. The revised set that were posted:

SURVEYPart1_[Company]_[Facility]_[ProcessUnitID]_rev111009.xls

3. A separate set of the forms that has the revisions highlighted in red. Form tabs that had a change are colored red as

Summary of Revisions Made From First Set of Posted Spreadsheets to the Spreadsheets Now Posted:

SURVEYPart1

Form B-1: Changed "intrinsic viscosity" to "inherent viscosity". 

The submitted forms from GGC Aberdeen listed inherent viscosity on Form B-1.

Form C-1-c: Corrected the Liquid Loading Rate from "L/m3" to "gpm" (Did you submit your data in gpm?)

The worksheet appears to be set up for continuous flow, trayed stripping columns. However, the facility 

utilizes batch wastewater strippers; therefore no liquid loading rate was entered into the worksheet and 

the change in units has no affect on the submitted survey.

Form D: Changed "Does the heat exchange system cool process fluids that contain HAP?" to "Does the heat exchange 

system heat or cool process fluids that contain HAP or VOC?".

On the submitted survey our reply was “Yes”. With the rewording of this item the answer is still “Yes”.

Form J: Corrected the reference from Form G-1 to Form I.

None of the changes listed on Form I were from new source review requirements. Most changes were part 

of company motivated process improvements.

SURVEYPart2

Form K-1-a: Changed flow rate units from "scfm" to "dscfm" (cell E16). (Did you submit your data in dscfm?)

No, the data submitted was total scfm not converted to nor measured on a dry basis.

Form K-1-b: Changed units from ppmv to allow users to select "ppmvd @ 3% O2", "ng/dscm @ 3% O2" or "ug/dscm @ 

3% O2". (What format did you use?)

Answers were submitted as ppm.

Form K-1-c: Added a "Basis for Emissions Values" column for each HAP instead of only one column for all HAP.

This form required the creation of additional worksheets. The basis for emission values for each HAP listed 

on Worksheet K-1-ca is a model created for Title V permitting activities. The other K-1-c worksheets list 

only VCM, the basis for which is the residual VCM concentration of resin leaving the stripping column (or 

reactor used as a stripper) and conservatively assuming all VCM is then emitted through the various 

emission points located between the stripping operation and rail car loading (EPs 15-34, 37-46).

Form K-2-a: Added a "Basis for Flow Rate Value" column for each Process Stream ID instead of only one column for all 

Process Stream IDs at the end. Added text at the top of the Form to clarify that "This Form should be completed for 

streams of ALL phases, except gas/vapor streams."

The basis for each stream is listed separately in the last column. The basis was “measured” for streams 

that have flow meters and “calculated” for others. The form includes all streams, excluding vapor and gas 

streams.
Form K-2-b: Removed "Units" columns and the option to select "ppmv" or "ppmw"--consolidated with 'Concentration" 

column. (Did you submit your data in ppmv or ppmw?)

No data was submitted on this Form. This worksheet requests concentration data for streams downstream 

of the stripping operations. As was discussed in the original coverletter, the facility measures the residual 

VCM concentration of the resin leaving the stripping operations. However, the facility does not currently 

analyze the water portion of the slurry for pollutants. Without such information, the calculation of the 

concentration of VCM in the stream itself is not possible. The sampling event required as a component of 

this survey will, however, provide analytical results describing the concentration of VCM, as well as those 

of the other identified pollutants contained in the approved sampling plan, in both the liquid and solid 

phases of the slurry in a number of these streams.

Form K-3-b: Removed "Units" columns and consolidated with "Concentration" column.

Data was submitted as ppmw, parts per million by weight. 

Form L: Changed "Concentration at Equipment Opening" units to "ppmvd @ 3% O2". (Did you submit your data in 

ppmvd @3% O2?)

No, the data is not submitted in ppmvd @3% O2. Data in that format is not available.

Form M: Changed "Concentration Immediately Prior to Removal From Equipment and Before Being Mixed With Other 

Materials or Fluids (ppm)" to "Concentration in Resin or Resin Slurry Immediately Prior to Removal From Equipment and 

Before Being Mixed With Other Materials or Fluids (ppmw)" (Cell C18). (Did you submit your data in ppmw?)

The approved sampling plan contains an “off-spec pile” section that details the efforts Georgia Gulf will 

take during the upcoming sampling event to quantify the emissions related to this resin.

Form N: Changed "Concentration (ppm)" to "Concentration (ppmw)" (Did you submit your data in ppmw?)

Yes, data submitted is in ppmw units.

Form O: Changed "Number of turnovers per campaign" to "Number of turnovers." Changed "Concentration (ppm)" to 

"Concentration (ppmvd @ 3% O2)". Added a column for "Total Emissions (pounds)". (Did you submit your data in 

ppmvd @3% O2?)

We have no equipment that falls into this category, this sheet is marked NA for not applicable. No data 

was entered.
