I was asked by someone to explain Untility Mark Outs so here goes (my spelling is horrible so bear with me). In New Jersey and many other states a I understand it you must obtain a utility mark out prior to doing ANY diging even on your own property but especaily on a customers. Basicly in NJ you call 1(800)272-1000. An opperator picks up the phone and asks you: 1. Location of the diging (full street address) 2. Person your doing the diging for (Full name and phone number) 3. Where on the property you will be diging (they ask you how deep and to mark the area out in white paint, i always tell them to mark the whole property out just in case.) 4. It takes anywhere from 1 month to two weeks to get the mark out completed, the operator puts i a work order and all the public utilities must come out and mark thier lines that are in the ground. Power, Telephone, Gas, Cable TV, public sewer lines etc. 5. NOTE THEY DO NOT MARK OUT WHERE THE CUSTOMERS SEPTIC TANK IS! Failure to get a Utility mark out in NJ can result in being ticketed by local PD or public works dept depending on what county your in AND if you hit a public utility line YOU are wholy reasponsible. So lets say you knock the power out to the local radio station three blocks away and they loose 100K an hour you will get sued for that 100k an hour (yea they probably do have backup generators but its just and example). It really does give you more confidance to when digging because your not constantly worried if your going to pull up an old power line. IN NJ if your going to remove dirt/move dirt you must also obtain a trip permit.
