However, if marking <br />and/or lighting are accomplished on a voluntary basis, we recommend it be installed and maintained in <br />accordance with FAA Advisory circular 70/7460-1 K Change 2. <br />See attachment for additional condition(s) or information. <br />Any height exceeding 70 feet above ground level (164 feet above mean sea level), will result in a substantial <br />adverse effect and would warrant a Deten-nination of Hazard to Air Navigation. <br />This determination expires on 11/29/2009 unless extended, revised or terminated by the issuing office. <br />NOTE: REQUEST FOR EXTENSION OF THE EFFECTIVE PERIOD OF THIS DFUERMINATION <br />MUST BE POSTMARKED OR DELIVERED TO THIS OFFICE AT LEAST 15 DAYS PRIOR TO THE <br />EVIRATION DATE. <br />This determination is based, in part, on the foregoing description which includes specific coordinates and <br />heights.
