shall have the following protection:
Preformed concrete barriers, bollards, or other physical barriers should be installed
in such a fashion that if the barriers are impacted and knocked over, they will not
strike the well head.
High visibility flags should be extended above the well head to a height that will able
to be seen by mechanical equipment operators. Flags wll be mounted to poles.

that are driven 5 feet into the ground. If the Jersey barriers are used it would be recommended that
