Much like the ozone layer crisis was resolved by outlawing the production and use of ozone-depleting substances (primarily CFCs), acid rain has been mitigated somewhat by much more stringent emissions standards in power plants and cars.
E.g., here's what NOx emissions in the US have been over the last 50 years:

Emissions peaked in 1980 at 27,079,000 tons; last year they were 7,645,000 tons. A 72% drop in 40 years.
