Union Hill Water Treatment Plant
Phoenix, AZ · near Phoenix Deer Valley (2.6 mi)
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
"Temporary use of mobile cranes (Liebherr LTM 1220-5.2 max height 276 ft AGL and Liebherr LTM 1160-5.1 max height 175 ft AGL) for rigging and placement of water treatment equipment (butterfly valves weir gates and actuators) during the UH WTP Phase 1 Filter MOD Valves and Actuators Replacement project (City of Phoenix Project No. WS85320025). Cranes will be staged intermittently within the plant's filter gallery construction area between October 2026 and January 2027 and removed from the site upon completion of lift operations. Maximum working/boom height during lift operations is 175 ft AGL; 276 ft AGL reflects the maximum tip height in transport/standby configuration."
