However, if marking/ <br /> lighting are accomplished on a voluntary basis,we recommend it be installed and maintained in accordance <br /> with FAA Advisory circular 70/7460-1 K Change 2. <br /> This determination expires on 06/08/2016 unless extended, revised, or terminated by the issuing office. <br /> NOTE: REQUEST FOR EXTENSION OF THE EFFECTIVE PERIOD OF THIS DETERMINATION MUST <br /> BE E-FILED AT LEAST 15 DAYS PRIOR TO THE EXPIRATION DATE. AFTER RE-EVALUATION <br /> OF CURRENT OPERATIONS IN THE AREA OF THE STRUCTURE TO DETERMINE THAT NO <br /> SIGNIFICANT AERONAUTICAL CHANGES HAVE OCCURRED, YOUR DETERMINATION MAY BE <br /> ELIGIBLE FOR ONE EXTENSION OF THE EFFECTIVE PERIOD. <br /> This determination is based, in part, on the foregoing description which includes specific coordinates and <br /> heights. Any changes in coordinates and/or heights will void this determination. Any future construction or <br /> alteration, including increase to heights, requires separate notice to the FAA. <br /> This determination does include temporary construction equipment such as cranes, derricks, etc., which may be <br /> used during actual construction of a structure. However, this equipment shall not exceed the overall heights as <br /> indicated above. Equipment which has a height greater than the studied structure requires separate notice to the <br /> FAA. <br /> Page 1 of 3 <br />
