Certain of the Company's lease agreements include renewal options to extend the agreements and certain leases include escalation clauses and/or purchase options. These leases do not contain any financial covenants for the Company. Minimum lease commitments payable by the Company for noncancelable operating leases are as follows:

Total rental expense was $38.0 million, $37.3 million and $40.7 million in fiscal years 2018, 2017 and 2016, respectively. Legal and Environmental Matters In the ordinary course of conducting its business, the Company becomes involved in litigation, administrative proceedings and governmental investigations, including environmental matters. On April 28, 2016, the Company was served with a lawsuit filed by Ector County, Texas and the State of Texas by and through the Texas Commission on Environmental Quality ("TCEQ") alleging violations of the Texas Solid Waste Disposal Act, the Texas Water Code, the Texas Clean Air Act, and TCEQ rules on spill prevention and control. The Plaintiffs amended their petition in February 2017 to include violations of TCEQ rules on recycling and storm water permits. The Plaintiffs further amended their petition in April 2017, broadening their allegations. The lawsuit, filed in the 201st Judicial District Court of Travis County, Texas, alleged improper disposal of solid waste and unauthorized outdoor burning activity at the Company’s recycling facility located in Odessa, Texas. The lawsuit sought a penalty for each day of alleged violation under the Texas Health & Safety Code, the Texas Water Code, or the Texas Administrative Code. The parties agreed to a mediated settlement on December 1, 2017 and entered into an Agreed Final Judgment on June 12, 2018. The Agreed Final Judgment was approved by the State of Texas on July 24, 2018. Under the settlement, the Company paid $1.1 million, net of insurance recoveries. The Company denies any wrongdoing in connection with the alleged claims, and the settlement does not contain an admission of liability from the Company. The Company has received notices from the U.S. Environmental Protection Agency ("EPA") or state agencies with similar responsibility that it is considered a potentially responsible party at several sites, none of which are owned by the Company, and may be obligated under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 ("CERCLA") or similar state statutes to conduct remedial investigations, feasibility studies, remediation and/or removal of alleged releases of hazardous substances or to reimburse the EPA for such activities. The Company is involved in litigation or administrative proceedings with regard to several of these sites in which the Company is contesting, or at the appropriate time may contest, its liability at the sites. In addition, the Company has received information requests with regard to other sites which may be under consideration by the EPA as potential CERCLA sites. Some of these environmental matters or other proceedings may result in fines, penalties or judgments being assessed against the Company. At both August 31, 2018 and 2017, the Company had $0.7 million accrued for cleanup and remediation costs in connection with CERCLA sites. The estimation process is based on currently available information, which is in many cases preliminary and incomplete. Total environmental liabilities, including CERCLA sites, were $4.0 million and $4.3 million as of August 31, 2018 and 2017, respectively, of which $1.9 million and $2.1 million were classified as other long-term liabilities as of August 31, 2018 and 2017, respectively. These amounts have not been discounted to their present values. Due to evolving remediation technology, changing regulations, possible third-party contributions, the inherent shortcomings of the estimation process and other factors, amounts accrued could vary significantly from amounts paid. Historically, the amounts the Company has ultimately paid for such remediation activities have not been material. Management believes that adequate provisions have been made in the Company's consolidated financial statements for the potential impact of these contingencies, and that the outcomes of the suits and proceedings described above, and other miscellaneous litigation and proceedings now pending, will not have a material adverse effect on the business, results of operations or financial condition of the Company.
