There is a Notice to Airmen on file, advising that the lighting on that tower is "unserviceable" until 9/16, which means that whoever is responsible for maintaining the tower lights is aware of the problem and has "notified" the proper authorities.
Presumably this means that there is a plan to repair the lighting on or before 9/16, although NOTAMs for tower light failures can be extended.
FCC Rule 17.48 states that failure of any flashing light, or any top-mounted steady-burning light on a structure, must be reported to the FAA within 30 minutes of failure. There is no specific requirement to have tower lights repaired within a certain time frame, although pilot complaints may cause the FAA/FCC to put some pressure on the tower owner.
