There might be one less roadblock to redeveloping Qualcomm Stadium’s Mission Valley site.

Twenty years ago, a series of gas leaks from nearby Mission Valley Terminal – the region’s gas hub – created a huge plume underground that caused petroleum and byproducts to creep beneath Qualcomm Stadium.

Since then, there’s been plenty of speculation that the gas plume would complicate a Mission Valley stadium deal.

But it appears the clean-up efforts in the years since the leak have been a success, and state water board officials are saying contamination isn’t really a concern anymore.

Lisa Halverstadt and NBC 7’s Artie Ojeda explain what’s left to do before the site gets the all-clear.
