, Georgia Bibb County

 **Site Location :**  The former Macon Naval Ordnance Plant (MNOP) s ite is located at 600 Guy Paine Road, in an industrial area of Macon, Bibb County, Georgia

. The MNOP is approximately 34 3 acres, which extend s from Guy Paine Road to the north, Mead Road to the east, Rocky Creek to the south, and the Central of Georgia Railroad tracks to the west.

 **Site History:**
In 1941, the MNOP site was acquired by the Department of Def ense (DOD) , and w as operated by the U.S. Navy for

the manufacture of ordnance and explosives , including flares, small primers, detonators and other triggering

mechanisms . In 1965, the DOD sold the site to Maxson Electronics Corporation (Maxson). Maxson als o manufactured

ordnance at the site. M NOP had several buildings, explosive demolition and testing areas, fueling facilities, above and below ground storage tanks, solvent storage buildings, explosives storage areas, a metal plating facility, laboratories, a landfill area and a sewage treatment plant.

In 1973, the site was sold to Allied Chemical Corporation (Allied). Allied manufactured seatbelt components at the site until 1981, when they sold the site to a current owner, Macon

- Bibb County Industrial Aut hority. Since 1981 a number of parcels have been leased and/or sold to various entities. The site is currently known as the Macon

- Bibb County Allied Industrial Park

.

 **Site Contamination/Contaminants:**

and pesticides (DDT, DDE, alpha

- chlordane and gamma

- chlordane). G round water contaminat ion, with high levels of

trich l oroeth yl ene (TCE) and its breakdown products, originat es from the o ld wastewat er treatment plant, migrates

under the site and has been detected in the wetlands area of Rocky Creek.

 **Potential Impacts on Surrounding Community/Environment :** 
Contaminated soil and ground water have contaminated Rocky Creek and the associated wetlands . There are no drinking water intakes on Rocky Creek, but Rocky Creek is designated as a fishery.

 **Response Activities (to date):**
No response actions have been taken to date.

 **Need for NPL Listing:**

The EPA is proceed ing with NPL listing because the U S Army Corp s of Engineers ( USACE ) has withdrawn plans to investigate and remediate the site and is not address ing the site under its Formerly Used Defense Site program due to

the existence of other potentially responsible parties . No other state or federal authorities are available to address the

site. The EPA received a l etter of support f or placing this site on the NPL from the state.
