Clearance follows testing, analysis of air quality in sewers by State and County health officials
Wayne County, Mich. - The Wayne County Health Department and the Michigan Department of Health and Human Services (MDHHS) have determined that Flat Rock's Zone 2 is clear of any impact from the Ford plant gas leak and that residents who chose to evacuate can return home.
Zone 2 is an area that public health officials believed needed further investigation of potential chemical exposure, but that the risk didn't warrant an evacuation recommendation. Instead, Wayne County Health Department and MDHHS advised Zone 2 residents that they could consider leaving their homes while the investigation was ongoing, if they were not comfortable staying. This area is bounded by Gibraltar Road to the north, Sheeks to the west, East Huron River Drive to the south, and Tamarack Road to the east, as well as buildings along Woodruff between East Huron River Drive and Cahill Road and includes 635 homes.
"I know evacuation has been a hardship for many Flat Rock residents, but it was critical that health experts took the time to collect and analyze sufficient data so that residents can have peace of mind returning to and remaining in their homes," said Wayne County Chief Operating Officer Genelle Allen. "Our team has worked closely with the MDHHS, the EPA, the City of Flat Rock and other agencies to protect residents' health and safety."
MDHHS and the Centers for Disease Control and Prevention used data from 12 houses across Flat Rock that initially had elevated benzene levels or gasoline odors inside their homes to confirm that sewer testing can be used to validate that air levels in homes are below health levels.
MDHHS compared the indoor air quality data in those 12 homes with test results for sewer lines and confirmed that gasoline-related sewer vapors were substantially prevented from entering the indoor air of those homes. This health-protective approach has been used under similar conditions in Wisconsin. Based on extensive sewer gas testing throughout Zone 2 and the 12-home confirmatory data, MHDDS concluded that the indoor air of other homes in Zone 2 will not be at risk of being impacted from benzene or other gasoline-related chemicals now that the gasoline release has been stopped.
"I'm pleased that Zone 2 residents now have assurance that the gas leak is not impacting the air quality in their homes," said Dr. Joneigh Khaldun, Michigan chief medical executive and MDHHS chief deputy director for health. "Our team will continue to work hard along with our partners from state, local and federal agencies as we assess screening and monitoring data from Zone 1 swiftly and thoroughly. Out of an abundance of caution, our recommendation to Zone 1 residents is that they remain evacuated until we know from the data that they can return home."
Ford continues to provide families in the affected areas of Zone 1 and 2 with hotel accommodations in local hotels. While Zone 2 has been cleared for residents to return home, Ford will continue to provide hotel accommodations for those residents in Zone 2 who requested testing at their home and are still awaiting their written results. If residents need accommodations, they can call 734-782-2455 extension 1105.
The Wayne County Health Department and MDHHS are working to complete the Zone 1 process as quickly as possible in the coming weeks.
