What this outcome means
The FAA studied the proposal and concluded it would not be a hazard to air navigation. A no-hazard determination is not permanent — it carries an expiration date, and if the structure is not built by then the case has to be re-filed.
The proposal, in the filer's words
"Requesting Lower Height (AGL). Reduce Stack 3 by 260 vertical feet.Adjacent Stack 2 will remain at 500 vertical feet AGL. Stack 2 250 horizontal feet away from Stack 3.NOTE: Scrubber stack ASN#2012-ASO-11634-OE is located to the northwest of Stack 2 and Stack 3.NOTAM #03/390 XNX has been issued for Stack 3 during its demolition."
