Back in '99, we built a rather large addition onto our home. We got all the necessary permits and got started. The first thing that needed to be done was the extra lot next to us needed to be lowered so a footer could be poured. A woman that lived directly behind us, down the hill on the street below (henceforth known as the 'crazy lady'), drove up on our street, as the backhoe was working the land, and told us we couldn't dig on our property because of coal mines beneath it.
I told her we had the permits, and the work would be done. She started trying to argue with me, and I just shook my head, pointed at my front window, said, "There's the permit," and walked away. In a huff, she got in her car and left. 20 minutes later, a man from the city permit office drove onto the street and told me a complaint had been registered, and he had to investigate. He went and looked over the hill, and told us a barrier needed to be put up so dirt and rocks would not roll over the hill to the property below. An hour delay. Back to work.
The next day we had quite the surprise. A car with federal tags drove up and parked in front of the house. It was 2 men that worked for the EPA!! They told us a complaint had been registered that we had dug down so far the we were into some 100 year old coal mines beneath our property. Well, my chin hit my chest at the sound of this one. I told them to look around, there were no sinkholes in my property. He laughed and said, "A lady on the street behind you, had an old coal mine that was leaking out some toxic liquid called us a few years back. We, per policy, filled it in and closed it off at no charge to her. But she has had us come back several times to check it. Now she thinks you're going to dig into it."
He asked if we were going down any further and I told him no. I asked him how much further we would have to dig to get into the coal mine, and he said "50 feet. At least. You could dig an in-ground swimming pool if you wanted. Further if anything happened that your property fell in and was damaged because of the mine, federal regulations say we would have to fix it or compensate you for the full amount of your loss.
