OUR HISTORY IN BRUNSWICK

Hercules Brunswick facility, circa 1960.
For more than a century, Hercules has been a part of the fabric of Brunswick, Georgia’s coastal community. The Brunswick facility, located on Glynn Avenue near the causeway bridge, began operations in 1911. With the exception of a pause during the Great Depression, it continued for more than a century. In its earliest era, the site produced rosin and other derivative products from salvaged pine tree stumps, part of the naval stores industry that defined this region’s economy for generations.
As state and federal environmental regulations developed over the following decades, Hercules’ approach to the site evolved alongside them and much has been accomplished to address the environmental legacy of these historical operations.
A NEW CHAPTER
Generations of Brunswick people worked at the Brunswick facility when it was operated by Hercules, and then by Pinova from 2010 through 2023. Even after its operations ceased, Hercules has been conducting environmental remediation and restoration at three sites in Brunswick. A timeline summarizing the history of operations and remediation at these three sites is below.

| 1911 | The Brunswick naval stores plant opened, using an innovative new process to extract rosin from pine tree stumps. |
| 1920 | Hercules began operating at the Brunswick facility, producing rosin and turpentine from pine stumps. |

| 1984 | The |
| 1990s | Hercules continued investigation and remediation at the plant. It removed and remediated an equalization basin and above-ground storage tanks in the northern portion of the facility and conducted biological treatment in the area to prevent contaminants from being carried in groundwater. |
| 1993 | The Environmental Protection Agency (EPA) approved Hercules' remediation plan for the 009 Landfill. |

| 1999 | Hercules completed construction of the 009 Landfill cap and installed a comprehensive monitoring system. |
| 1999 - 2000 | Hercules removed approximately 30,000 tons of contaminated sediments from the outfall ditch and adjacent creeks and entered into an agreement with EPA to evaluate risks and additional remediation. |
| 2000s | Hercules continued its investigation to identify areas for remediation. Hundreds of acres, above and below ground, were sampled and studied extensively. |
| 2001 | Fish tissue sampling conducted by the Georgia Environmental Protection Division (EPD) showed improvement in fish tissue quality after Hercules’ remediation of the outfall ditch and creeks. |
| 2005 | Hercules conducted follow-up fish tissue sampling, confirming continued improvements in fish tissue quality. |
| 2005 | Hercules begins leasing a portion of the 009 Landfill cap to the neighboring auto dealer for use as a part of its car lot adding an asphalt cap on top of the exisitng landfill cap. |
| 2007 | The state relaxed fish consumption advisories after remediation activities in the outfall ditch and the adjacent creeks resulted in improvements. |
| 2008 - 2010 | Hercules remediated the former toxaphene production plant and the N-Street ditch: demolishing the plant, excavating 47,000 tons of soil from the plant and the ditch, backfilling the plant area, and relining the ditch. |
| 2010 | Pinova purchased the operational portions of the Brunswick facility. |
| 2010s | Hercules further investigated groundwater conditions, assessed potential risks, and conducted additional remediation work. |
| 2012 | Hercules investigated the outfall ditch to design the next phase of remediation. |
| 2014 | The Wildlife Habitat Council (WHC, now Tandem Global) certified the wildflower field planted on a portion of the Brunswick facility. |
