2)         Any construction or alteration of greater height than an imaginary surface extending outward and upward at one of the following slopes:

A)        100 to 1 for a horizontal distance of 20,000' from the nearest point of the nearest runway of the airport, with at least one runway more than 3200' in actual length.

3)         Any object that would be shielded by existing structures of a permanent and substantial character or by natural terrain or topographic features of equal or greater height, and would be located in the congested area of a city, town, or settlement where it is evident beyond all reasonable doubt that the structure so shielded will not obstruct or interfere with aircraft using the airport, or cause any additional adverse effect on airport operations by considering the height and location of the existing uses and structures.

c)         Form and Time of Notice

1)         Each person who is required to notify the Department under Paragraph (a) of this section shall forward one (1) executed form set (in four copies) of the Department's Form No. DA-39 (for an example, see Exhibit A) to the Division of Aeronautics, One Langhorne Bond Drive/Capital Airport, Springfield, Illinois  62706.  Copies of this form may be obtained from the Department.
