The EPA is getting ready to issue a new rule on methane release later this year. It goes beyond previous regulations for oil/gas producers and affects things like storage tanks, so may have an impact on even small-scale releases.

It's a very strong greenhouse gas, a significant contributor to warming, and because its life in the atmosphere is only a few years, reductions in emissions would get results quickly. And most of the man-made emissions would not be that hard to curb. By itself it wouldn't solve the long-term problem, but a serious reduction in methane emissions, if started soon, would buy significant time for dealing with the much-more-difficult CO2 issue. So there's growing interest in doing that; expect rather stronger regulatory pressure to reduce methane emissions.

For natural-gas emissions, much of the problem is leakage in production and distribution rather than releases at the customer end, but depending on how the rules are written, yeah, it could end up affecting even small deliberate releases.
