This may be a legal question.

In Massachusetts is it illegal or is it against OSHA policy or law to plug tires instead of patching tires?

No, it is not against the law or OSHA policy by plugging a tire.
There is no written law or policy that prevent this practice.

Although this practice is legal many retail shops have their own rule (patch only rule).
