I never doubted for a moment that forced closure of a theme park would actually be happening. However in a world post Blackfish and things, any thing could happen.
Hopeful chances are this park will be able renew its environmental licence in due time. If the situation relates to the park getting a fine from the authority, the park could surely claim legal action against those who were supposed to validate the licence (as Baron said).
This then just leaves the problem with the woodie. Depending how well the outcome is, how will they reduce noise levels considering original testing was too loud? High fences, sound tunnels, specific materials to quieten the roar, preventing guests from screaming? Surely not.
Safe to say this is sort of a Plopsa style situation to what happened at Paultons 6/7 years ago. Hopefully they've got this.
