U.S. Environmental Protection Agency
Air Study at Grenada Stamping
Information for Workers
February 2017
Introduction
Last year, EPA directed Grenada Manufacturing, LLC to perform indoor air sampling in the manufacturing building
(commonly known as Grenada Stamping and currently operated by Ice Industries). Sampling performed by the Facility's
contractor in October 2016 showed elevated levels of trichloroethene (TCE) in the Facility's indoor air and areas beneath
the concrete floor. Follow-up sampling performed in January 2017 continues to show elevated levels of TCE inside the
Facility (results are summarized in the table below).
In response, the Facility is increasing ventilation and air exchange within the building (to immediately reduce TCE
concentrations) and designing an engineered mitigation system for long-term effectiveness.
More information about EPA's ongoing work to oversee the cleanup of the site is posted at: www.epa.gov/grenadacleanup.
January 2017 Sampling
Findings from the October 2016 and January 2017
sampling are similar. Additional locations were
sampled in January in the manufacturing and office
areas. TCE was found to be above the screening
level in all occupied indoor areas tested during both
sampling events. TCE was found to be above the
screening level in five of the six sub-slab samples
taken during each of the sampling events. EPA uses
screening levels to help determine if further
evaluation should take place.
During January, TCE was found to be above EPA's
Removal Management Levels (RMLs), also called
"action levels," in the same five locations previously
sampled in October and in two new sampling
locations. RMLs are values used by EPA to help
determine if any future actions may be needed. A
determination that a sample result is higher than a
RML by itself does not imply that adverse health
effects will occur.

Worker Health
The health effects of ICE depend upon the pathway, concentration, and time (i.e., length of exposure) to the chemical.
Long-term exposure to ICE vapors could pose potential health risks. Women in the first trimester of pregnancy are most
vulnerable because of the potential for cardiac malformations in a developing fetus during the 3-week period where the
heart forms. Some women may not be aware of their pregnancy during the critical period of the first trimester, so all
women of reproductive age are considered to be among the sensitive population.
If you have health questions, you may want to consult your doctor. The Agency for Toxic Substances and Disease Registry
(ATSDR) has TCE exposure information available for you and your doctors upon request. The materials explain how you can
be exposed to TCE, and how it affects your health. For more information, contact:

Actions Being Taken
¦* wu- n§)
The Facility is implementing the following immediate interim and long-term response
actions, with EPA oversight, to reduce indoor air concentrations of TCE below Removal
Management Levels (RMLs) in all areas of the building.
Sampling conducted in January 2017for
TCE inside the Facility
Immediate Interim Measures:
•	Increasing building pressurization and/or ventilation;
•	Continued sampling of indoor air to confirm that TCE levels have decreased; and
•	Monitoring the movement of occupants in high TCE areas to limit exposure.
Long-term Measures:
•	Sealing potential conduits in flooring where sub-surface vapors may be
entering the building;
•	Treating indoor air (carbon filtration, air purifiers); and
•	Installing an engineered sub-slab depressurization system (to remove sub-
slab vapors before they enter the building).
