S.B 637 requires all contractors and subcontractors to use the federal E-Verify program to confirm employment eligibility of all employees before beginning work on a public project. The PA Department of General Services will issue a compliance verification form that employers must submit before being awarded a project or executing an existing project. They will enforce the act through complaint-based and random audits. Contractors violating the Act will be subject to debarment for up to 180 days and civil penalties ranging from $250 to $1,000 per violation. Willful violations will be subject to debarment for up to 3 years.
