SUBJECT: Amended Third Quarter 2016 Toxic Air Pollutant Emissions Report
Chemours Company — Fayetteville Works
Air Permit No. 03 73 5T42
Facility ID: 06/09-0900009
Bladen County, North Carolina
Dear Mr. Vozzo:
On October 18, 2016, the Chemours Company — Fayetteville Works submitted to your office
the third quarter 2016 Toxic Air Pollutant Emissions Report as required by Sections
2.2(B)(1)(c) and 2.2(B)(2)(e) of the subject Title V Air Permit. That report inadvertently
failed to include the reporting of an exceedance of methylene chloride that occurred on
July 28, 2016, as required by Section 2.2(B)(1)(c)(i). To correct that omission, this amended
report is being submitted.
Section 2.2(B)(1)(a) of the subject permit sets a facility -wide emission limit of 24.85 pounds
of methylene chloride per hour.
On July 28, 2016, 84 pounds of methylene chloride leaked from a copper tubing fitting. The
duration of the release was two hours, therefore the average emission rate was 42 lb/hr,
which exceeded the 24.851b/hr maximum emission rate for methylene chloride.

The leak was a result of a copper tubing compression fitting that was inadvertently cross -
threaded during the initial installation. The cross -threading prevented the ferrule from being
properly compressed and forming a seal. The fitting eventually began to leak the methylene
chloride. After the leak was discovered, it was isolated via block valves and that section of
tubing with the leaking fitting was removed and replaced with a new piece of copper tubing.
The attached Table 1 gives the facility -wide emissions of toxic air pollutants. Except for
methylene chloride, all facility -wide toxic air pollutant emissions were below the respective
permit limits listed in Section 2(A) of the referenced permit.
To comply with the requirement of Section 3(D) of the subject permit, the required
photocopy of this letter is enclosed.
If you have any questions, please feel free to call me at [phone].
