USA Swimming said it is investigating the allegations against Mirande.
"Unfortunately, we have been unable to obtain critical information from the individual bringing forward the complaint, although other individuals with whom our investigator has spoken have been quite helpful," USA Swimming said in a statement earlier this week.
Lynn Johnson, an attorney representing the female swimmer in the lawsuit, said the family had been urging USA Swimming to investigate the coach for months, but "Nothing happened until the impending "20/20" show."
Also named as a defendant in the suit is Aaron Dean, Mirande's former immediate supervisor at the Kansas City swim club and currently a registered USA Swimming coach at the Virginia swim club that is suspending Mirande.
According to the suit, Dean "knew or should have known of Mirande's acts of inappropriate sexual conduct" and therefore "acted in consort, aided, abetted and/or encouraged" Mirande's violation of USA Swimming's Code of Conduct which prohibits sexual contact between coaches and athletes.
In an email to ABC News, Dean "adamantly" denied the charges against him and said, "I am interested in learning more about the suit, who filed these erroneous claims and what they are seeking from me."
Dean, Occoquan Swimming, and the club's president Brad Hughes did not immediately respond to ABCNews.com about Mirande's suspension.
Also named as defendants are Missouri Valley Swimming, one of the country's 59 local swim committees, and the local swim club Kansas City Dolphins, for, among other allegations, failing "to provide an environment that is safe and free from inappropriate conduct from registered US Swimming coaches." The general manger of the Kansas City Dolphins, Robert Sturman, said he had not been served with the lawsuit and was unaware of its allegations.
Shortly after the ABC News investigation, USA Swimming Executive Director Chuck Wielgus said he was "extremely sorry if our organization has not done enough to provide the highest level of child protections safeguards and guidelines."
Wielgus announced that the organization is working to establish an anonymous abuse reporting hotline for swimmers and is considering a 'Black List,' which would publish the names of USA Swimming coaches banned for sexual misconduct.
