<br /> With respect to obstructions in general we call your attention
<br /> to Part 77,J121 (c) of the Federal Air Regulations (cony enclosee
<br /> which- states: _
<br /> •
<br /> "the stand in this subpart apply to the effect of con-
<br /> strnctidn or alteration proposals upon an airport if, at
<br /> the ti mel of filing notice . . . (1) (the airport is) avail-
<br /> able for public use and is listed in the Airport
<br /> Directory. . ,,
<br /> • . . _ -: 7,'
<br /> After reviewing these regulations, it is my opinion that -
<br /> 1
<br /> 1. The requlrements for approach zone control and or-
<br /> ship are mandatory only for airports receiving federal
<br /> aid funds.
<br /> I
<br /> 2. Even ,for airports for which compliance s mandatory,
<br /> the requirements extend only to the outer end of the
<br /> clea-r zone as defined in 152.9 (b) .
<br /> I . . _ . • 1.
<br /> 3. The requirement for reporting and review is applicabl,- k,
<br /> only 1pn new construction or substantial alteration,
<br /> at the time of the construction.
<br /> In conclusion, it appears that if Midway Airport were a federal
<br /> aid airport, it would be required by statute to concern itself
<br /> only with obstructions in the clear zone. It would, the-re=ore,
<br /> seem appropriate for Orange County to only require Midway Airpor
<br /> to have sufficient land interest in the areas defined as "clear
<br /> zone" .
<br /> If I may be of further assistance, please let me know.
<br /> Sincerely,
<br /> •
