Licensing
Tree removal permits
Ask your city or county government whether removing a tree needs a permit where you live.
Trees near power lines
If a tree is touching the power line to your house, keep clear and call your utility first. Clearing the line is the utility's job, and a tree company can't start until it's done.
In Connecticut the federal OSHA rule is the one that applies: workers who aren't trained for line work keep 10 feet from lines up to 50,000 volts.2
811 and stump work
Spraying and treating trees
In Connecticut the arborist license is itself a commercial supervisory pesticide certification, in category 3D Arborist.1
