If you believe a natural gas or oil operation near your house is making you sick – maybe you were breathing in dust from trucks, or losing sleep due to round-the-clock drilling – how would you voice your concerns? Could you be sure someone was actually listening? Would you know if others shared your health concerns? The answers to those questions vary widely state to state: In Colorado, state health or staff of the Colorado Oil and Gas Conservation Commission respond to complaints and log them in a public database. In North Dakota, your complaint will be logged and addressed, but the database isn’t public.
