Addyston Air Monitoring
Continuous Air Monitoring
Due to continuing concern about the air quality in Addyston, Ohio
near the LANXESS Corporation plant, this Agency has
purchased a monitor to continuously measure various volatile
organic compounds (VOC). The monitor which augments the every
six-day monitoring is located at the Meredith Hitchens
Elementary School and provides real-time air monitoring data. If the
concentration of VOC in the ambient (outside) air exceeds a
pre-determined level, immediate notification will be made to the
Miami Township Fire Department so an investigation can be done to
determine what action if any needs to be taken in response to the
ambient concentrations. The elementary school and LANXESS will also
be notified if the concentration exceeds the pre-determined level.
Protocol for Air Sampling
Data
Purpose: Air samples will be collected
at the Hitchens School using SUMMA canister technology as part of
the Hamilton County Department of Environmental Services (HCDOES)
Toxics Air Monitoring program. The data will be collected for a
period of about 1-year. This protocol describes how that data will
be processed and communicated.
Sampling and Analysis Overview: SUMMA canisters are evacuated cylinders that
collect ambient air samples over a variable period of time, usually
specified for 24 hours for the long-term averages used for chronic
risk assessment analysis. The sample is then sent to a lab (Data
Chem for this location) for analyses of organic compounds using the
USEPA method TO14, a GC/MS technology. The sampling location
will also have weather instruments to capture wind speed and direction
during the sampling time period.
Data Management: Data will
be submitted from the lab to HCDOES and Lanxess Corporation. The
data will be reviewed for errors, missing compounds, and QA/QC
(quality assurance/quality control)
results. Any errors will be resolved before making the data
available to the public.
The data will include the concentrations for 61
compounds. The detected values will be listed, in parts per
billion, in a table. Wind speed and direction for the 24-hr
averages will be provided.
RESULTS OF SUMMA CANISTER SAMPLING –
ADDYSTON LOCATION
Note: The results reported below are part of a
1 year study. Results are reported individually to provide current
data to interested parties, however, these results should NOT solely
be used to make final risk decisions. Ohio EPA, after the
study is completed, will review the data and provide a complete
report.
Note: This data will
be considered draft until it undergoes Ohio EPA review.
Note: The 2004 Air Toxic Monitoring
Data for Carthage, Lower Price Hill, and Winton Place is provided to
give an idea what the concentrations have been at other monitoring
sites.

Health Based Standards
The following are several health based
standards for Styrene, Acrylonitrile, and 1,3 Butadiene, which are
air contaminants emitted from the Lanxess facility.
Note: For informational purposes only,
the most appropriate air standards to compare potential acute (short
term) exposures are the American Industrial Hygiene Association
Emergency Response Planning Guidelines (ERPGs). This set of
exposure limits is divided into three categories representing
exposure to increasing concentrations of specific chemicals:
ERPG-1: The maximum concentration in
air below which it is believed nearly all individuals could be
exposed for up to one hour without experiencing other than mild,
short-term health effects or the detection of a clearly defined
objectionable odor.
ERPG-2: The maximum concentration in air
below which it is believed nearly all individuals could be exposed
for up to one hour without experiencing or developing irreversible
or other serious health effects or symptoms.
ERPG-3: The maximum concentration in air
below which it is believed nearly all individuals could be exposed
to up to one hour without experiencing or developing
life-threatening health effects.
The table below lists several ERPG-1:

Threshold limit values (TLVs) refer to airborne concentrations of
chemical substances and represent conditions under which it is
believed that nearly all workers may be repeatedly exposed day after
day, over a working lifetime, without adverse health effects. TLVs
are developed to protect workers who are normal, healthy adults.

Newly installed air contaminant (pollutant)
sources must comply with Ohio EPA’s Air Toxics Policy. The Air
Toxics Policy determines the maximum acceptable ground-level
concentration (MAGLC). The MAGLC is determined for each pollutant
by dividing the threshold limit value by a factor of 42.
