Biennial Report for the Manufacture of APFO

Calendar Years of 2002 and 2003

DuPont Company – Fayetteville Works

Note: The information contained in this document is submitted voluntarily and may be

subject to future revision and/or modification.

COMPANY SANITIZED PUBLIC COPY

This report is submitted pursuant to commitments made by DuPont in a March 14, 2003,

Letter of Intent (LOI) to Stephen L. Johnson, Assistant Administrator, USEPA, entitled

“Voluntary Actions to Evaluate and Control Emissions of Ammonium Perfluorooctanoate

(APFO).

Pursuant to Addendum III of this LOI, provision 5, a facility manufacturing APFO is required

to, beginning in the year after production commences, and continuing for five consecutive

years following, for the prior calendar year, report to EPA biennially the following

information on a calendar year basis:

1. Annual production volume of APFO;

2. Emissions per facility (air, water, waste);

3. Summary report of groundwater monitoring results;

4. Summary report of surface water monitoring results;

5. Workplace industrial hygiene monitoring; and

6. Summary data on employee blood monitoring results.

This report provides the above information for calendar years 2002 and 2003.

Annual production volume of APFO ATTACHMENT 2

The DuPont Company – Fayetteville Works’ APFO Manufacturing Facility commenced

production in late 2002. The following table shows the total production volume of APFO

for calendar years 2002 and 2003.

Calendar Year APFO Production

2002 [CBI]

2003 [CBI]

1. Emission per facility (air, water, waste);

The DuPont Company – Fayetteville Works’ APFO Manufacturing Facility has estimated

the quantity of PFOA emitted to the atmosphere as air emissions using engineering

calculations. In addition, stack testing performed in 2003 showed the PFOA emissions to

be less than the analytical detection limit.1 Annually a sample of the site’s surface water

discharge to the Cape Fear River is analyzed for PFOA; however that monitoring shows

the PFOA to be less than the quantification limit of the analytical method. The waste

emissions are the quantities of PFOA, on a dry basis, that are estimated to have been

present in the various solid waste streams transferred from the Fayetteville Works site.

The following table gives the estimated emissions of APFO to specific media from the

Fayetteville Works during the subject years:

Emission Media 2002 2003

Air 17 lb. 22 lb.

Water Note 1 NQ

Waste 35 lb. 3,236 lb.

Note 1: Due to the late start-up of the APFO Manufacturing Facility

and the short duration of the 2002 production run, no surface

water monitoring occurred in 2002.

NQ = less than the practical analytical quantification limit of 0.05 g/L

2. Summary report of groundwater monitoring results

In 2002, the DuPont Company – Fayetteville Works performed air dispersion modeling

to determine the most probable locations for the atmospheric deposition of PFOA from

the new manufacturing facility. New monitoring wells were installed in the surficial

aquifer at the two locations predicted by the modeling.

1 While APFO is the substance manufactured at the facility, the substance measured by analytical techniques is

the perfluorooctanoate anion (PFOA)

Confidential

Business

Information
ATTACHMENT 2

In 2003, the Fayetteville Works site began annual monitoring of the groundwater for

PFOA. The monitoring involved the two newly installed wells described above, and

included two existing monitoring wells.

Groundwater monitoring conducted in January and March 2003 showed no quantifiable

levels of PFOA in the two new wells and the existing well at the Old Biosludge Lagoon

(SMU-01, SWM-02, and MW-1S respectively). These monitoring events did indicate

levels of PFOA above the quantification limit at the existing well located upgradient of

the Nafion® Common Sump.

Following discussions with the North Carolina Division of Waste Management, the 2004

groundwater monitoring was expanded to include three existing wells downgradient of

the Nafion® Common Sump area. The 2004 monitoring results were virtually identical

to those in 2003, and the three above-mentioned downgradient wells showed PFOA

concentrations of 0.303 g/L, 1.530 g/L, and 0.123 g/L respectively. It is believed

that the detected PFOA is a result of a historical release originating from the Nafion®

manufacturing area’s common process wastewater sump. That source has been

eliminated from the site.

3. Summary report of surface water monitoring results

As reported in Item 1 above, the DuPont Company – Fayetteville Works annually

monitors for PFOA in the site’s surface water discharge to the Cape Fear River. The

monitoring conducted in both 2003 and 2004 shows the PFOA to be less than the

quantification limit of the analytical method, or less than 0.05 g/L. No surface water

monitoring occurred in 2002 due to the late start-up of the APFO Manufacturing Facility

and the short duration of the 2002 production run.

4. Workplace industrial hygiene monitoring

The DuPont Company – Fayetteville Works began workplace monitoring for PFOA with

the start up of the APFO Manufacturing Facility in 2002. The workplace monitoring in

2002 and 2003 consisted of stationary area monitors that sampled the building air space

for twelve (12) continuous hours. These sampled locations are limited access restricted

areas in which personnel wear both respiratory and dermal personnel protection. The

analytical results reported in the following table are the 12-hour time weighted average

(TWA) PFOA concentration values.

2005 [CBI]

7. Emission per facility (air, water, waste)

For air emissions, the quantity of APFO emitted to the atmosphere in 2004 and 2005 from

the site was estimated using engineering calculations.

For surface water emissions, annually a sample of the site’s final surface water discharge to

the Cape Fear River is tested for the presence of APFO2. For 2004 and 2005, results

showed APFO to be less than the analytical method’s quantification limit of 0.050 g/L

(0.050 parts per billion). The reported emissions were calculated using this analytical result

(<0.050 g/L) and the average discharge flow rate (12.397 million gallons per day in 2004

and 10.441 million gallons per day in 2005).

The waste emissions are the quantities of APFO, on a dry basis, that are estimated to have

been present in the various solid waste streams transferred from the Fayetteville Works site.

The following table gives the estimated emissions of APFO to specific media from the

Fayetteville Works during the subject years:

Media 2004 2005

Air 47.3 lb. 55.5 lb.

Water <1.9 lb. <1.6 lb.

Waste 9,914 lb. 10,019 lb.

8. Summary report of groundwater monitoring results

In 2004, 2005, and 2006, the Fayetteville Works site continued the annual groundwater

monitoring for APFO that began in 2003. The monitoring involved both newly installed

wells and existing monitoring wells. All groundwater and surface water concentrations are

reported as APFO (see footnote 1 on this page). This report also provides results available

as of May 30, 2006

2 While APFO is the substance manufactured at the facility, the substance measured by analytical techniques is the

perfluorooctanoate anion (PFO). The commercial laboratory converts this analytical result to an APFO value via

molecular weight calculations. For consistency with the previously submitted biennial report for this site, results

are reported as the calculated APFO values.

Monitoring of stagnant water in a stormwater conveyance ditch was conducted in 2005.

While this stagnant water meets the definition of a surface water, it should be noted that this

water consisted of exclusively non-flowing puddles of water at the time of the sampling.

Sampling of two unnamed tributaries to the Cape Fear River, and two streams flowing to

one of those tributaries, was conducted in 2006. It is believed that the base flow in these

tributaries is primarily from expressed groundwater, with additional episodic flow from

stormwater runoff. The surface water samples described in the table that follows were taken

during base flow conditions. The results of that monitoring are shown in the following

table:

In 2005, the site’s non-contact cooling water and the influent and effluent of the river water

sediment basin were sampled. Both of these waters ultimately discharge through the site’s

NPDES permitted Outfall 002. The non-contact cooling water is raw river water that is

pumped from the Cape Fear River, through equipment to remove heat, and then back to the

river. The river water sediment basins receive river water and its sediment that has been

removed from the river water as a result of clarification. The results of that monitoring are

shown in the following table:

10. Workplace industrial hygiene monitoring

The DuPont Company – Fayetteville Works began workplace monitoring for

perfluorooctanoic acid (PFOA) with the start up of the APFO Manufacturing Facility in

2002. The workplace monitoring in 2004 and 2005 consisted of stationary area monitors

that sampled the building air space for twelve (12) continuous hours. These sampled

locations are limited access restricted areas in which personnel wear both respiratory and
dermal personnel protection. The 12-hour time weighted average (TWA) PFOA

concentration values are shown in the following table:

Additional monitoring information

Additional APFO monitoring information that is not specified by the LOI is being reported in

Appendix A of the site’s Phase II RCRA Facility Investigation (RFI) Report. This additional

information will be the analytical results for APFO concentrations of samples taken of soil,

sediment, ambient air, and the Cape Fear River. A copy of the Phase II RFI Report was

submitted to the N.C. Division of Waste Management on June 30, 2006 and will be provided to

EPA Docket OPPT-2003-0012 as a separate submission.
