The way I interpret this:

"The new study says O'Hare can handle just 190 to 200 arrivals and
departures per hour, fewer than a 2001 study that recommended a
maximum of 200 to 202 flights per hour."

it would seem that the Meigs closure has reduced ALL operations at
O'Hare by up to 5%. So it would seem that the Meigs closure has had a
negative impact on O'Hare.

I don't read it that way. I read it as saying that the 2001 study was
simply incorrect. Not that the closure of Meigs somehow reduced the
capacity of O'Hare. I don't even see how it [the demolition of Meigs] could have.

Meigs used to support 20,000 operations a year. Some of that traffic
surely now uses O'Hare. So while the demolition of Meigs field may
not have reduced the capacity of O'Hare, it has exacerbated congestion
there.

Without the text of the two FAA studies, it not possible to
definitively understand the exact cause of the revised O'Hare capacity
limits. The AvWeb article alludes to "gridlock" as the cause, but it
is unclear if that would air, surface, or automobile gridlock.

The latest FAA study has recommended a reduction in the TOTAL number
of operations at O'Hare, unfortunately this reduction is being
selectively applied to GA operations.

Right. Again, it's GA's problem, not O'Hare's.

It's an O'Hare problem that has be addressed by selectively reducing
the number of GA operations there.

The question is, what authority has implemented the reduction in GA
operations? If it's the FAA, presumably it's consistent with their
guidelines. If the reduction imposed on GA operations at O'Hare is
the result of the city of Chicago's fiat, it may be inconsistent with
their Airport Improvement funding agreement with the FAA.
