Emphasis my own:

There are plans to add *15 more gas turbines between June 2025 and June 2030*, and the turbine application projects *annual emissions of around 11.51 tons of hazardous air pollutants*."

I wonder what the pollution from these gas turbines is like. SO2 from trace sulfur compounds? Is it much worse than a traditional gas-fired power plant for some reason? I can't imagine it would be but I have to plead ignorance and beg for hints here.

So they haven't gotten permits, but why? Why where the permits denied?

Just the other day we had news that some Californian environment protection agency denied permits for SpaceX for political reasons as opposed to following objective rules, as ruled by a judge. So the fact that some permits were not issued doesn't tell me anything.
