In 1997, Menard was caught using his own pickup truck to haul plastic bags filled with chromium and arsenic-laden wood ash to his home for disposal with his household trash. Menard pleaded no contest to felony and misdemeanor charges involving records violations, unlawful transportation, and improper disposal of Hazardous waste. Menard and his company were fined $1.7 million for 21 violations.
In January 2008, Menard gave $15 million to support Eau Claire's Luther Midelfort Hospital. The donation will be used for a new emergency services department and to help Mayo Clinic educate and train health professionals. In 2015, Menard donated $10 million dollars to support the Eau Claire Area YMCA. The gift will replace the current five-court LE Phillips Tennis Center that opened in 1972 to become an eight-court indoor tennis center known as the Menard Family YMCA Tennis Center.
In 2013, Menard ousted a former investment partner, Stephen Hilbert, a 20% shareholder in MH Equity, for mismanaging assets and resources.
