Item 4. CONTROLS AND PROCEDURES

As of June 30, 2022, with the participation of our management, our Chief Executive Officer (principal executive officer) and our Chief Financial Officer (principal financial and accounting officer) carried out an evaluation, pursuant to Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended (the “Act”), of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Act). Based upon that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2022.

There have been no changes in our internal controls over financial reporting, as defined in Rule 13a-15(f) of the Act, in the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. LEGAL PROCEEDINGS

Information regarding our litigation and legal proceedings can be found in Note 10 to the Consolidated Financial Statements, which is incorporated into this Item 1 by reference.

In September 2013, U.S. Environmental Protection Agency (“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. In the Fall of 2020, EPA referred the matter to the U.S. Department of Justice and EPA Headquarters for civil judicial enforcement. In July 2022, a court notice was filed regarding a final settlement agreement providing for a civil penalty of $324,000 and the installation of monitoring and control equipment. Following a public comment period, we expect entry of the settlement by the court.

In April 2022, the State of Texas filed suit against Equistar Chemicals, LP, in Travis County District Court seeking civil penalties and injunctive relief for alleged violations of the Texas Clean Air Act related to multiple emissions events at Equistar’s Bayport Plant. We reasonably believe resolution of this matter will result in payment of a penalty in excess of $300,000.
