Modern aero derivative power turbines are capable of operating at below 15 ppm NOx when properly fitted for use. It's not as if they aren't making any attempt at all with regard to emissions. They've been working on this stuff since the 90s. They're on 2nd and 3rd generation combustor technology now. That said, a parking lot full of these things could eventually crank up the ambient NOx levels. The real problem is low stack height. The exhaust being close to the ground creates a hot spot that would have otherwise dispersed into a much larger volume of air. One generator running by itself is probably not an issue in any arrangement. 20 is a medium sized power plant.
