Dhemson Inc. violated the reporting requirements of section 8(a) of TSCA, 15 U.S.C. section 2607(a)(Reporting and Retention of Information), and the Inventory Update Reporting Rule. As a result of a September 11, 2008 inspection at Chemson's Philadelphia facility, EPA discovered that Chemson did not file all of the required forms for the 2006 rporting period as required under TSCA's Inventory Update Reporting (IUR) regulations (40 C.F.R. section 710.53). Chemson has since submitted the required information to the Agency. An administrative complaint was filed by the Agency on December 15, 2010 assessing a civil penalty ($260, 872) for the late filings. Respondent paid the full penalty and a Final Order was issued 3-4-11.
