"Disaster-related or emergency-related work" means repairing, renovating, installing, building, or rendering services or other activities necessary to mitigate damage to critical infrastructure resulting from a declared disaster or emergency during the disaster response period. "Disaster-related or emergency-related work" does not include (i) any activities that an out-of-state business or an out-of-state employee is paid to perform by the Commonwealth, a locality in the Commonwealth, or a registered business in Virginia or (ii) the sale of goods by an out-of-state business or an out-of-state employee to the Commonwealth, a locality in the Commonwealth, or a registered business in the Commonwealth.

A business entity that otherwise meets the definition of an out-of-state business maintains that status even though it is affiliated with a registered business if such affiliation is solely through common ownership.
