You also asked what is done about it. It really depends on the problem.
One of the things we're doing currently with our annual planning process is to come up with new and innovative ways to deal with problems. Primarily regional staff work on that. We have a manager at headquarters who leads it, but she works with a manager from each region. They roll up a lot of the input from their region to look at the problem and figure out the best enforcement intervention to solve that problem. Then we bring in people at the officer level, and they sit on working groups for the various regulations, and they're really the experts on that regulation in that regulated community. They come in as well to talk about how to make it really practical and tangible on the ground.
