(August 7, 2019)   Cobb Leaders Join Smyrna Effort to Test Air Near Sterilization Plant
An Oversight Committee will seek experts to do independent testing

Smyrna, GA - August 6, 2019 |  Cobb County leaders say they’ll accept an invitation from Smyrna’s mayor to join an effort to conduct independent air testing near a medical sterilization plant in District 2.   Smyrna Mayor Max Bacon asked County Manager Rob Hosack and Commissioners Bob Ott and Lisa Cupid to join an Oversight Committee that will include residents, business leaders and others from both the city and county.

The effort comes after a report raised concerns about Ethylene Oxide released from the Sterigenics Plant off Atlanta Road.  The EPA considers Ethylene Oxide a cancer-causing chemical, but Georgia’s Environmental Protection Division has said Sterigenics is “in compliance with current federal requirements for control of ethylene oxide emissions.”

“We need to make sure the community is protected, that people are safe,” said Mayor Bacon.  “The key is getting this going, getting the air tested and see where we go from there.”

The committee will include city and county officials, health experts, and other local stakeholders who will work with an Independent Air Quality Task Force of private technology experts to quickly implement a plan to test the air near Sterigenics and analyze the results.

A small group met with representatives of GHD, the company who did independent testing around the Sterigenics plant in Willowbrook, Illinois.  The company said testing could be set up in a few weeks, with some initial results a few weeks after that.  The committee will also reach out to officials in Atlanta to see if they would like to expand testing there.

“This is a great opportunity for the City of Smyrna and Cobb County to work together to give residents what they’ve been asking for; independent testing,” said Cobb Commissioner Bob Ott.  “This quick action shows the great relationship between the city and county.”

(July 23, 2019)  Statement from State Senator Jen Jordan on Sterigenics

As I indicated yesterday, disturbing reporting by Georgia Health News and WebMD revealed that Georgia’s Environmental Protected Division (“EPD”) has kept the public in the dark about an elevated cancer risk caused by the emission of ethylene oxide in the metro-Atlanta area.

This morning, with Rep. Erick Allen, I spoke with the President of Sterigenics and he has represented to me that the company will be submitting an application to Georgia EPD within 7 to 14 days that will seek EPD's approval for Sterigenics to install new emissions-reducing technology in its Cobb County plant that the company believes will significantly reduce emissions and bring down any emissions to an acceptable level.

If its application is approved by EDP, Sterigenics believes that the installation of the new emissions-reducing technology would then take approximately 12 weeks to complete. The company has said that it would put out a formal statement by the end of the day. Rep. Allen and I will post the statement once we have it in hand.

To be clear, these initial overtures are welcome, but they are just the beginning and will not cut off my office's efforts to ensure that the people that live in my district are not being harmed. I know that there is a lot of troubling information out there, but just know that we are working to get answers and solutions.


(July 23, 2019)  Commissioner Bob Ott’s office has reached out to state Environmental Protection Division officials after residents expressed concern about a medical equipment facility operating in a nearby Heavy Industrial area.

A recently-published article indicated the Sterigenics facility off Atlanta Road near the Chattahoochee River emits a gas that has been linked to cancer.  

“The county understands the concerns of people who live in the area,” said Commissioner Ott.  “Both my assistant and others with the county have had multiple conversations with Georgia EPD officials since the article came out and want to make sure the state is doing everything it can to monitor emissions from the plant.”

Ott’s office confirmed the Sterigenics facility is operating legally in an area zoned for heavy industrial use.  The company did not receive any incentives or tax breaks to locate there.

Georgia EPD officials tell us the company is currently in compliance with state regulations and has told them they are installing additional emission controls at their own cost.

The concerns were raised not because the plant is releasing more ethylene oxide gas, but because the US Environmental Protection Agency recently identified the gas as a carcinogen.  State EPD officials told Commissioner Ott’s office that since that change, new testing and analysis has been underway with results expected in the next few months.

“Even though the state has authority in monitoring emissions coming from the plant, I think it is important the county makes sure residents in the area get their questions answered and are briefed on any new results as soon as possible,” Ott said.
