Provide the amount of chemical identified abov e for the reporting year at specific site:

Imported (virgin) _ 0 kgs/yr

Imported (externally recycled) ___ 0 ___ kgs/yr

Manufactured ___ 0 ___kgs/yr

Estimate the amount of subject ch emical distributed off-site:

____ N/A

_____ % of manufacture/import

Provide the amount used (including any that was manufactured, imported [virgin or externally recycled], or internally recycled) of the subject chemical for the reporting year at specific site:

___ 0 __kgs/yr

Narrative Description and Process Flow Schematic :

Provide overall material balance of the ch emical being reported, showing releases and products (kgs/year). Use the following pa ge to provide a narra tive description and process flow schematic of on-site activiti es, and include information that gives an understanding of the nature and extent of potential exposur es to the subject chemical. Attach additional pages if desired. The narra tive and process flow schematic should cover major unit operations and chemical conversions for manufacturing and on-site uses, if applicable. The narrative should provide insight into why and how re leases are caused by the process. The schematic should show the poi nts of release of the subject chemical in the workplace and to the environment. In the event the subject chemical is used in many different processes, provide information on each major process instead of each individual

process.Narrative Description and Proce ss Flow Schematic for Decatur :

The use of APFO as a polymerization aid at De catur ended in December 2004. Therefore, there

were no PFOA releases from fluoropolymer related production for 2010. Fluoroelastomer production continues, but without the use of a fluorochemical polymerization aid.

IV. SITE RELEASE AND TRANSFER INFORMATION (For manufacturing and on-site processing/use if applicable)

In this section, estimate the total media-specific releases after on-site treatment of

the chemical from your facility. You may estimate the releases by using monitoring data or any other method you believe appropriate. Estimates should be reported in kgs per year for the reporting period. Enter the values as whole numbers to no more than two significant figures. For example, if your a nnual releases are estimated to be 12,360 kgs, an estimate of 12,000 kgs should be reported.

Estimate the number of days per year th e release occurs. Enter a whole number with a maximum of 2 significant figures.

Insert “N/A” for release activities not a ssociated with the chemical or “0” for

releases of less than 0.5 kgs per year.

For all releases, the source of data an d/or basis for determination should be described in detail. Suggested informati on about the possible s ources/basis includes:

1. If the source/basis is an analytical measurement, then

• Describe the method (i ncluding analytical standards used, sampling, sample treatment, analysis).

• Describe the uncertainties and assumptions made.

• Give the Level of Detection (LOD) /Level of Quantification (LOQ).

2. If the source/basis is a mass balance, then

• Show the mass balance calculation.

• Show that the mass balance closes.

• If the mass balance does not close, then report the fraction of total

feedstock that is not accounted for and the assumptions you made to

correct the balance. Describe the uncertainties.

3. If the source/basis is other than measurement or mass balance, then

• Describe the method used. For exampl e, if engineeri ng calculations areused, give a general description and state your assumptions . Describe the

uncertainties.

A. ON-SITE AIR RELEASES

Estimate the total fugitive or non-point releas es to air and the number of days per year the releases occur. Thes e releases include equipment leaks from valves, pump seals, flanges, compressors, sampling connections, and open-ended lines; evaporative losses from surface impoundments and spills; releases from building ventil ation systems; and, any other fugitive or non-point air emission.

In addition, estimate the total releases that occur through stacks, vents, pipes, or

other confined air streams as stack or point source releases. Include storage tank

emissions and releases from pollution control equipment.

If desired, you can provide estimates of the accuracies of your release estimates.

B. WATER RELEASES FROM SITE

Estimate the total releases of the chemical leaving the fence line of your facility from all discharge points to all streams or water bodies. Include all discharges from process outfalls such as pipes, open trenches, releases from on-site wastewater treatment,

and contribution from storm wate r runoff, if applicable. Do not include discharges to a

POTW or other off-site wast ewater treatment facilities. If desired, you can provide an estimate of the accuracy of your release estimate.

Water releases: _ N/A

_ _____ _ _

Enter the names of the streams or water bodies to which the facility directly discharges the chemical. Also, enter the NPDE S permit number for the facility. If more than one number is assigned to the facility, list each number for the appropriate discharge quantity and receiving water identified.

Receiving Water Name(s):__ Tennessee River

NPDES number(s):_ AL0000205

_

C. ON-SITE LAND RELEASES

Estimate the total releases of the chemical for each category of land disposal, if applicable. Estimate only on-site releases. Do not estimate leaks from landfills separately. This should be accounted for in your estimate of total landfill release.

Releases to land treatment/land amendment include all waste containing the chemical that is applied or incorporated into soil on-site. Do not include waste that is

landfilled.

Surface impoundments are natural to pographic depressions, man-made excavations, or diked areas formed primarily of earthen materials designed to hold an

accumulation of the chemical.

Underground injection is the technol ogy of placing fluids underground, in porous formations of rocks, through wells or other similar conveyance systems.

Other releases include any amount of the ch emical that is released to land other than those listed. An example is the acci dental release of the chemical from an underground pipeline or storage tank.

D. OFF-SITE TRANSFERS

Estimates of off-site transfers should be similar in accuracy and precision to previous release estimates.

Dl. Transfer to Publicly Own ed Treatment Works (POTW)

Number of days/year the release occurs: _ N/A

_

Estimate the total quantity of the subject chemical , not the waste stream, transferred to the POTW. Complete section below for each POTW to which your facility discharges wastewater containing the ch emical. Enter the POTW’s NPDES permit number, if known.

In this section, estimate th e quantity of the subject chemical , not the waste stream, transferred and the accuracy of the estimate fo r each category listed. If your facility sends the subject chemical in waste to an off-site location where some of the chemical will be recycled and the remainder will be treated, estimate each amount separately (i.e., waste treatment and recycling activities).
