Ohio Case Studies
1,1,1-trichloroethane is the most commonly used cleaning solvent reported under the Toxic Chemical Release Inventory in Ohio, but production will be phased out by the end of 1995.
The following case studies represent successful efforts and cost savings in aerospace, metal container, metal and electrical parts, casting , weld inspection, silkscreen cleaning, painting and lubricant applications. The case studies document the efforts of Ohio companies to reduce or eliminate TCA. The companies have overcome obstacles and barriers to achieve this, and are willing to let others benefit from their experiences. The Ohio EPA believes these companies are pioneers in setting the standard for pollution prevention in Ohio. They are commended for their outstanding efforts.
