FIELD OBSERVATIONS:

On May 17, 2024, Hao Zhu of the Division of Waste Management and Radiation Control conducted an
inspection of the Hexcel property and the former Hercules cool water pond owned by Hercules Ins. The
inspection was conducted with Brian Smith of Geosyntec Consultants. In 1990s, Hercules sold its carbon
fiber production on a land of 80 acres to Hexcel Corporation (Hexcel), but remained the ownership for an
area of 7.42 acres including the former cooling water pond.

The land use conditions for Hexcel and the pond remained unchanged within a fenced and guarded
industrial complex. The access to the Hercules Bacchus pond can only entered through the Hexcel
guarded gate (Photo 1). The perimeter of the pond adjacent to the Hexcel and ATK properties is secured
by chain-link fencing and a locked gate. There are warning signs (Photo 2) along the fence marked with
words “Hazardous Area”, “Keep out”, or “No Unauthorized Excavation Permitted”. The former pond that
has been dry for decades.

It is not anticipated that the land use conditions for both Hexcel and the fenced pond area will be
changed in near future. The pond is totally land locked by the Hexcel property and a sliver of the
Northrop Grumman property to the north of the pond.
