the confusion that remains. AAAE should pursue clarification, and conceivably, revision of the AC with
FAA representatives in Washington D.C.
Hazardous Wildlife Attractants / Aviation Stormwater Manual Task Force
The Washington State Department of Transportation (WSDOT) has received an Airport Improvement
Grant from the FAA to develop a stormwater manual to address hazardous wildlife attractants over the
course of the next year. Over the last several months WSDOT has been developing the background
information on hazardous wildlife attractants, stormwater facilities, and on federal and state regulatory
requirements, and will present the information to their Task Force before preceding to the next step.
AAAE will monitor the development of the manual for availability to members. For more information on
the scope and progress of the project, go to the following link:

Issues with Potassium Acetate as a Runway Deicer
Reports have been circulating throughout the industry that potassium acetate causes damage to aircraft.
In addition, industry debate regarding the likelihood of it being a contributing factor to concrete
disintegration has resumed. In discussions on AAAE conference calls, it was noted that asphalt surfaces
are not included in the debate but there may also be suggestions that the chemical is damaging to inpavement
lighting. Boeing and Airbus have sent out a joint letter suggesting it is causing harmful affects
on carbon braking systems and called for an industry meeting to discuss the issue. One member noted
that the affects are most likely to affect newer concrete surfaces and that the longer the concrete has to
cure the less the impacts should be.
AAAE and ACI have now issued tandem statements calling for airports to stay the course until more
definitive plans of action are developed through industry coordination.
Non-Standard RSAs and EMASS Issues
The FAA currently has a prioritized list of non-standard RSA work to be done at airports with the easiest
being at the top of the list. FAA seems to be positioning itself to champion EMAS as an option for
correction but there is inconsistency in application across the country. In one case, use of a displaced
threshold as a fix was declared discriminatory. Other airports have displaced the threshold with no
impact. Many airports have expressed concerns that EMAS will become the FAA’s mandated response
for safety areas that do not meet standards and would prefer to leave all options open for resolving each
airport’s problems on a case-by-case basis. Such options can include displaced thresholds, adjustment
of declared distances, etc. Decisions to use EMAS should also consider it’s less than desirable
performance in wet and cold climates.
New FAR Part 139 Training Issues
Airports across the country have expressed numerous concerns on the impacts of the changes such as:
The lack of FAA approved standardized training guidance at the national level.
The 12 consecutive month training requirement and the difficulty in airports independently developing training
syllabi with little or no FAA guidance.
How the FAA will conduct the annual on-site certification process.
Discussions on these issues are continuing and an initiative to establish a AAAE national repository of
documentation from airports with approved materials is under investigation.
There are also continuing concerns with the Wildlife Management Program which has been adopted and
published by the FAA despite the comments they received. Issues remain with the training requirements
of the program, particularly the train-the-trainer options. AAAE is preparing a fact sheet to address any
remaining uncertainties.
ISSUES RECENTLY DISCUSSED
FAA’s NPRM on Part 77 and TERPS
Earlier this summer, the FAA proposed to amend the regulations governing objects that may affect
navigable airspace. Specifically, the FAA is proposing to add notification requirements and obstruction
standards for electromagnetic interference and amend the obstruction standards for civil airport
imaginary surfaces to more closely align these standards with FAA airport design and instrument
approach procedure criteria.

The FAA has also proposed requiring proponents to file with the agency a notice of proposed
construction or alteration of structures near private use airports that have an FAA approved instrument
approach procedure. This proposal, if adopted, would also increase the number of days in which a notice
