Each State - actually each county - has to meet the Clean Air Standards to receive the funding.

So they may be meeting their standards without going after tailpipe emissions.

If I remember correctly, NH had several choices and felt that was the one that had the least amount of impact. The OBD system was less intrusive and costly than the actual tail pipe testing, and meant that NH didn't have to focus on other sourcing.
