Horseracing Integrity and Safety Act of 2020 This bill recognizes the Horseracing Integrity and Safety Authority for purposes of developing and implementing a horseracing anti-doping and medication control program and a racetrack safety program. The authority shall establish an anti-doping and medication control standing committee and a racetrack safety standing committee to provide guidance to the authority on the development and maintenance of the programs. The Federal Trade Commission (FTC) shall have oversight over the authority. The authority shall submit to the FTC any proposed rule, standard, or procedure developed by the authority to carry out the horseracing anti-doping and medication control program or the racetrack safety program. The authority shall seek to enter into an agreement with the U.S. Anti-Doping Agency or an entity equal in qualification under which the entity acts as the anti-doping and medication control enforcement agency under this bill. Among the required elements of the horseracing safety program are sets of training and racing safety standards consistent with the humane treatment of horses, a system to maintain track surface quality, programs for injury and fatality analysis, investigation and disciplinary procedures, and an evaluation and accreditation program. The bill sets forth other provisions regarding (1) funding, conflicts of interest, and jurisdiction; (2) registration with the authority; (3) program enforcement; (4) rule violations and civil sanctions; (5) testing laboratories; (6) review of final decisions of the authority by an administrative law judge; (7) unfair or deceptive acts or practices; and (8) agreements with state racing commissions.
