I would like to address the financial impact of the FCC?s belief that white strobe lighting should be the preferred system for tower obstruction lighting and let others discuss whether there are any merits for even considering the lighting system change. As required by the Regulatory Flexibility Act, the FCC said it has prepared an initial report regarding the possible significant economic impact on small businesses of the policies and rules proposed in their NPRM. They said it is set forth in Appendix A. But there are no details at all in Appendix A. Regarding the proposed lighting change, the FCC knows that it will have a significant financial impact, but it is difficult to identify that impact because an individual or association is not able to capture enough information in the FCC?s Antenna Structure Registration database to figure out how many towers will be affected by the proposed changes when the tower is modified with a new collocation or altered in any way. Since medium intensity white lighting is being considered as the preferred system, the cost would be based upon the existing or new tower?s height. A CTIA spokesperson said recently in a news article that to change the lighting could cost at least $30,000 per tower. A PCIA representative said it could cost $100,000 to do one tower. The expense they project might be correct for a specific tower, but the range of pricing doesn?t provide any accuracy in identifying the cost to an individual owner and the national impact on small businesses. I?m sure that both of those associations want to be more specific in their cost projections if they are going to present them to the FCC to identify an economic hardship. However, I don?t know how they can capture this data without more information from the FCC regarding the number of structures this will affect and the structures? height. Costs of the equipment and installation can be provided. In example, if an owner were to change an incandescent system on a 300? tower to a medium intensity lighting system, if the company was local, the cost would be approximately $6,000 to $9,000 for the work ? considerably less than $30,000. On the other hand, if you were to change out a 1,500? tower it would require high intensity lighting and the cost could skyrocket to $175,000 as the article on wirelessestimator.com points out. Until the FCC provides additional data that interested parties can use to assess the economic impact that their change would effect, no changes to obstruction lighting regulations should be considered or enacted.
