The Alamance-Burlington School System may have violated some state-mandated budgeting procedures as well as its own policies in its awarding of a contract to deal with toxic mold in a number of school buildings last summer, a state legislative committee says.

State Sen. Amy Galey, R-Alamance, released late Wednesday a letter sent to her by the Joint Legislative Commission on Governmental Operations questioning the school system's management of mold remediation efforts.
