(a) A person who releases a hazardous substance on the Airport shall immediately contain and clean up the release, using methods that ensure that contamination does not enter or spread on or in Airport land or water or in an Airport storm water drainage system. A person responsible under this chapter for a release shall immediately report the release to the Airport Manager and to each regulatory agency that requires such a report. Submission of a report to the Airport Manager under this subjection does not satisfy any other applicable requirement for reporting a release of a hazardous substance to any regulatory agency that has jurisdiction.

(b) If a person responsible under this chapter for a release does not take immediate action to report, contain, and clean up the release, the City may report, contain, or clean up the release as the City determines appropriate under the circumstances. The City may seek reimbursement for the City’s costs of assessment, reporting, containment, and cleanup, as applicable, from any person responsible for the release.
