Item 3. Legal Proceedings.

Environmental Matters

From time to time we and our joint ventures receive notices or inquiries from government entities regarding alleged violations of environmental laws and regulations pertaining to, among other things, the disposal, emission and storage of chemical and petroleum substances, including hazardous wastes. Item 103 of the SEC’s Regulation S-K requires disclosure of certain environmental matters when a governmental authority is a party to the proceedings and the proceedings involve potential monetary sanctions that we reasonably believe could exceed $100,000. The matters below are disclosed solely pursuant to that requirement.

In September 2013, the Louisiana Department of Environmental Quality (the “LDEQ”) issued a Compliance Order and Notice of Potential Penalty to Equistar Chemicals, LP pertaining to self-reported deviations arising from our Lake Charles, Louisiana polyolefins plant and relating to certain Clean Air Act Title V permit conditions, limits and other requirements. The matter involves deviations reported by us to the LDEQ in semi-annual reports covering 2007 through June 2011. We reasonably believe that LDEQ may assert an administrative penalty demand in this matter in excess of $100,000.

In September 2013, the EPA Region V issued a Notice and Finding of Violation alleging violations at our Morris, Illinois facility related to flaring activity. The Notice generally alleges failures to monitor steam usage and improper flare operations. Region V indicated at a December 2017 meeting that it intends to issue an administrative enforcement order in 2018. We reasonably believe that EPA Region V may assert a penalty demand in excess of $100,000.

In June 2014, EPA Region V issued a Notice and Finding of Violation alleging violations at our Tuscola, Illinois facility related to flaring activity. The Notice generally alleges failure to conduct a valid performance test and improper flare operations. Region V indicated at a December 2017 meeting that it intends to issue an administrative enforcement order in 2018. We reasonably believe that EPA Region V may assert a penalty demand in excess of $100,000.

In August 2015 the Victoria plant experienced a hexane leak into the cooling water system which resulted in estimated emissions of 154,000 pounds of hexane over a 12-day period from the cooling water pond operated by the site host, Invista. In November 2017, the Texas Commission on Environmental Quality (the “TCEQ”) issued a proposed agreed order to both Invista and Equistar assessing a proposed penalty of $300,000. We are currently in discussions with TCEQ.

In March 2017, the TCEQ issued a proposed Agreed Order to Houston Refining LP. The proposed Agreed Order stems from agency record reviews conducted from May to July 2016 and September to October 2016 and an agency investigation conducted in April 2016. In June 2017, TCEQ issued a revised Agreed Order that carries a total administrative penalty of $77,626. The Agreed Order is currently awaiting final TCEQ approval.
