Avient was formed as PolyOne Corporation on August 31, 2000 from the consolidation of The Geon Company (Geon) and M.A. Under the agreement, The Geon Company agreed to indemnify Goodrich Corporation for certain environmental costs at the site. Neither Avient nor The Geon Company ever operated the facility.
