Conyers chemical plume after BioLab fire updates | Much of metro Atlanta smelling chlorine, seeing haze; Gwinnett says nothing hazardous detected

Rockdale County issued updated guidance at 3:20 a.m.

CONYERS, Ga. — Conyers, a city of roughly 17,000, has been evacuated and surrounding Rockdale County, with a population of nearly 100,000, is under shelter-in-place guidance continuing into the early morning hours of Monday after a fire at a BioLab facility and resulting chemical plume.

Meanwhile, in the later morning much of metro Atlanta -- most directly in Gwinnett County, which borders Rockdale to the north, but also the City of Atlanta and elsewhere -- reported the smell of chlorine and in some parts, a haze descended on their communities.

Gwinnett County Public Schools has canceled outdoor activities and cut outside air from coming into buildings, a statement on the district website says. The county government said before noon that EPA had not picked up anything of concern on its mobile monitors in Gwinnett, and said its county Fire and Emergency Services Hazardous Materials team did not detect anything hazardous.

Rockdale County provided updated guidance at 3:20 a.m. Monday morning.

Those sheltering in place are advised that "the best practice is to turn the air conditioning off and keep windows and doors shut."
  • What's in the air: The presence of chlorine has been confirmed by federal EPA and state EPD testing, Rockdale County said. What, if any, other chemicals might be involved has not been detailed.
  • What direction is the plume going?: Unclear as of 3:20 a.m., with the Rockdale release describing an "unpredictable path and wind direction."

  • Newton County Schools closed: Newton County is directly southeast of Rockdale. The schools in Rockdale County are on fall break starting today. Also, Georgia Piedmont Technical College's Newton and Rockdale campuses will be closed until further notice, a spokesperson said. 
  • Hospital situation: Officials said Piedmont Rockdale Hospital had evacuated some patients and that the hospital is on diversion. They asked anyone with an emergency situation to go to a hospital in a neighboring county.

Good morning, GCPS Families and Staff, 

Due to today’s shifting winds, and their impact on the chemical fire that occurred yesterday in Rockdale County, Rockdale County remains closed with a shelter in place order for their county. Due to our proximity to Rockdale County, the air quality in parts of Gwinnett County is also being negatively impacted. 

Because the safety of our students and staff remains our number one priority, please note our response in Gwinnett County Public Schools. For today, September 30, we have canceled all outdoor activities and events, and we have stopped outside air from coming into our buildings. We will continue to monitor the air quality, and we are in touch with Gwinnett County and the Department of Public Health regarding our best next steps to ensure safety.  We do know that Rockdale County has reported it may take some time for the fire cloud to dissipate.  Until the air quality improves, we encourage all families and staff to limit time outside, and keep windows and doors shut. 

We will continue to provide updates as they become available.

More on Conyers chemical plume | What happened?

County officials said that around 5 a.m., a sprinkler head malfunctioned, causing a mixture with a "water-reactive chemical," which in turn started a small fire on the building's roof. That fire was contained and put out, but reignited around noon. The fire was again put out around 3:30 in the afternoon.

The continuing chemical plume emanating from the site is, officials said, the result of water continuing to react with chemicals.

Rockdale officials stated this is the third incident at the facility in seven years involving products mixing with water and causing a chemical reaction.

What is BioLab?

According to its website, BioLab is based in Lawrenceville and is the "swimming pool and spa water care division of KIK Consumer Products."

The company makes brands, including BioGuard and SpaGuard, that it says "pioneered computerized water testing and the 3-step system for pool and spa care."

A similar fire and resulting chemical plume happened at a BioLab building in Conyers in 2004 -- it's unclear if the current situation is at the exact same site or perhaps a newer building. 

BioLab back in 2004 was owned by Chemtura, a conglomerate that went into bankruptcy and was later acquired by a German company called Lanxess. BioLab is now owned by KIK Consumer Products, according to its website, in a sale from Chemtura a few years before that Chemtura was acquired by Lanxess.
