Document:
Airports are eagerly anticipating new FAA reauthorization legislation to replace the FAA Modernization and Reform Act of 2012, which is due to expire on September 30, 2015. Approval of a new reauthorization bill is necessary to keep the FAA operating and funded. It is almost certain that Congress will not act by that deadline and a short-term extension of authority is most likely. (Last time, Congress enacted 23 short-term extensions before reauthorizing the FAA in 2012.) Short term extensions create funding uncertainties, especially for AIP-funded airport projects.
Increasing current PFC levels from $4.50 to $8.50 per enplaned passenger to reflect the effect of inflation and changed economic conditions since 2000 when the PFC level was last modified.
Assuring continued full funding for the Airport Improvement Program (AIP) and not allowing AIP funds to be used for FAA operations or other programs.
Reforming FAA regulation of airport economic and property development activities to allow airports to be more competitive and financially self-sustaining.
Preserving the tax-exempt status of municipal bonds and eliminating the Alternative Minimum Tax (AMT) burden on Private Activity Bonds.
In addition to those airport-specific issues, the debate on reauthorization is expected to raise broader issues of FAA reform. House Transportation and Infrastructure Committee Chair Bill Shuster (R-Pa) has announced his intent to consider wholesale reforms to the air traffic control line-of-business, including possible privatization or transfer out of the FAA, in order to expedite completion of NextGen and otherwise encourage the modernization of the air traffic control system. No date has been announced for the release of a full draft of the committee proposal.
In the months since the FAA announced the start of a rulemaking process to address the commercial use of small unmanned aircraft systems under 55 pounds (sUAS), demand for exemptions under Section 333 of the FAA Modernization and Reform Act of 2012 allowing the immediate use of sUAS has grown by leaps and bounds. In response, the FAA has streamlined the process for obtaining an exemption for commercial operations and granted hundreds of exemptions. The interim process still requires a case-by-case review of proposed operations, but relaxes previously-applicable restrictions. Until a final sUAS rule is adopted, the interim streamlined review provides the means by which persons seeking to use sUAS for commercial purposes can obtain authorization to legally operate their devices.
Stay certain distances away from airports or heliports.
One important operational change is the elimination of most geographical restrictions on COAs for sUAS. COAs issued under the interim process allow authorized operators to fly sUAS at or below 200’ above ground level anywhere in the country except in restricted airspace and other areas where the FAA prohibits sUAS operations, such as over major cities. This revised approach provides a great deal of flexibility to users such as real estate agents, property managers, surveyors, public utilities, still and video photographers, and agricultural producers to use sUAS where they wish outside of restricted areas.
Of particular interest to airport operators, exemptions granted since the spring of 2015 typically include a requirement that, if within the exclusion radii surrounding the airports, the sUAS operator must enter into an agreement with the airport for operations. As the use of sUAS proliferates, airport operators and local governments will likely face increasing pressure to regulate sUAS to address privacy, noise, land use, and other local concerns. Firm partner Allison Fultz recently published an article discussing the particular issues sUAS pose for airport operators and local governments. More information about the streamlined interim process can be found on FAA's website.
On May 7, 2015, the FAA announced that it was beginning work on a multi-year study to update the scientific evidence on the relationship between aircraft noise exposure and its effects on communities. The FAA intends to conduct surveys of residents near 20 airports across the country in order to survey public perception of aircraft noise. The FAA states that this will be the most comprehensive single aircraft noise survey conducted in the United States. The FAA did not identify the communities to be surveyed in order to preserve the scientific integrity of the surveys. The FAA expects the surveys to be completed by the end of 2016. After that, the FAA will analyze the data to assess whether to update the FAA’s guidelines and methodology for determining exposure to aircraft noise.
Since 1981, the FAA has relied on the DNL 65 decibel noise exposure level for its environmental review process and to make funding decisions for most noise projects near airports and for federal approval of noise abatement and mitigation measures pursuant to Part 150 and Part 161. The DNL metric is based on an average of all community noise over a 24-hour period, with nighttime noise weighted by a factor of 10 to account for the disruptive effects of nighttime noise. Use of the DNL 65 decibel guideline has not been without controversy, however, and a number of communities and stakeholders have urged the use of a methodology other than DNL and/or the use of a lower DNL decibel level.
A change in the current 65 DNL decibel guideline could have significant impacts on airport operators. The use of a different noise metric or DNL threshold could increase or decrease the number of homes eligible for federally funded acoustic treatment, home-buyouts, or other noise mitigation measures; could change mitigation obligations; and could change the scope of environmental reviews. In addition to federal issues, a new federal guideline, and publication of the survey results supporting the new guideline could affect airport operators under state lawsuits for inverse condemnation, trespass, and nuisance.
In November 2014, the FAA released an amendment to its Policy and Procedures Concerning the Use of Airport Revenue making explicit that the revenue use laws and policies apply to all taxes on aviation fuels, even if not imposed or collected by an airport sponsor. This amended policy is of great interest to airport sponsors because it potentially provides an important stream of additional state and local revenue to fund capital and operating needs.
The FAA has emphasized that the Policy amendment does not reflect new policy or law but is intended to remind local and state governments of their obligations under long-standing federal law. Under federal law, all taxes on aviation fuels must be used for airport purposes or state aviation programs. The clarification set forth in the amended Policy makes non-sponsors subject to revenue use obligations, and potentially subject to severe penalties for impermissible use of fuel taxes. Although the amended Policy makes clear that airport sponsors are not responsible for assuring compliance by non-sponsors—their obligations are discharged by informing non-sponsors of their obligations—the amended Policy is designed to remind many states and local governments of their accounting obligations because taxes on aviation fuels are often included in general sales or excise tax collections and are often dedicated to specific non-aeronautical uses under state law.
In response to a request for clarification from the National Association of State Aviation Officials (NASAO), the FAA provided additional guidance on the Policy. The FAA explained how it was going to interpret issues such as grandfathered taxes (those in effect before December 1987); how non-sponsors need to come into compliance with federal law; and how states can use offsets against other aviation expenses rather than directly dedicate fuel taxes to aviation.
On May 29, 2015, the FAA announced that it was replacing the separate modeling software packages used to analyze aircraft noise, fuel burn, and emissions with a single modeling software package called the Aviation Environmental Design Tool (AEDT), version 2b. AEDT replaces the separate modeling tools for aircraft noise (the Integrated Noise Model) and air emissions (the Emissions and Dispersion Modeling System). The FAA will require the use of AEDT ver. 2b to analyze aircraft noise, fuel burn, and emissions for purposes of environmental analysis under NEPA for analyses begun after May 29, 2015. Projects for which environmental analysis began before May 29 may continue to use the older modeling tools.
AEDT is not expected to result in material changes in the environmental analysis of airport projects. Additional information is available on the FAA’s AEDT Support web page.
Optimization of Airspace and Procedures in the Metroplex (NorCal OAPM). Lyons, et al. v. FAA, Case No. 14-72991 (9th Cir. Filed Sept. 26, 2014). The City of Phoenix recently challenged PBN procedures in the Phoenix airspace. City of Phoenix v. Huerta, Case No. 15-1158 (D.C. Cir. Filed June 1, 2015). Both cases are pending.
Revising the FAA Community Involvement Manual to include current requirements, best practices, lessons learned, and technological aids to improve community outreach.
Developing a community involvement plan to determine the appropriate level of community notification and involvement for each airspace matter identified in FAA Order 7400.2, Procedures for Handling Airspace Matters, Chapter 32, Appendix 10.
Developing improved procedures under FAA Order 7100.41, PBN Implementation Process, to assure that key airport staff are involved in the development of PBN procedures and community outreach strategies.
Involving airports in the Air Traffic Initial Environmental Review as part of the Order 7100.41 and Order 7400.2 process to identify potential environmental issues, potentially affected individuals, officials, community groups, or others who may be affected by, or have an interest in, the new procedures.
Forming a Noise Complaint Initiative to identify ways the FAA can address noise complaints in a clear, consistent, and repeatable manner.
The FAA did not set a schedule or specific process for implementing these changes. A copy of the FAA’s Responses to the NextGen Advisory Committee is available on RTCA's website, under General, 2015 Meetings.
On August 3, 2015 President Obama and the Environmental Protection Agency announced the Clean Power Plan Final Rule with its aim on the problem of climate change. Broadly, it aims to cut carbon emissions from power plants across the U.S. by 32% of 2005 levels by 2030. It directly targets carbon emissions from power plants, which are the largest carbon emitters. It places mandatory carbon reduction targets for each state to meet, but allows states flexibility in achieving the targets. Among various tools to meet these reduction requirements, the Clean Power Plan encourages expanded use of renewable energy and energy efficiency, and to a lesser extent efficient gas-fired energy. States can elect to address their reduction targets using an individual or a multi-state regional approach.
electricity generated by on-airport solar, co-generation and other projects more cost competitive. It is also possible that the number of proposed wind and concentrated solar energy projects near airports may increase to meet increased demand for larger-scale renewable energy.
On June 3, 2015, the FAA announced the start of a 10-15 year Runway Incursion Management (RIM) Program to develop methods to reduce the risk of runway incursions based on risk-based decision-making. The FAA is rolling out the program at a number of airports across the country with a past history of runway incursions. The program will focus on specific locations where incursions have occurred in order to identify specific risk factors that might contribute to a runway incursion and develop strategies to help airport sponsors mitigate those risks. The FAA states that the RIM Program is the next step in its long-term program to reduce airfield safety risks. Additional information is available on the FAA's website.
Organization’s (ICAO) process for setting international standards for CO2 emissions from aircraft. This announcement is the first step in the process that would allow EPA to adopt the ICAO standard when it is promulgated. The EPA will be taking comments on these proposals for 60 days. Additional information is available on EPA's website.
On August 4, 2015, the FAA announced proposed guidance on the procedures for communities affected by a new airport, a new or relocated runway, or a major runway extension to petition the FAA directly concerning the project. The proposed procedures implement 49 U.S.C. § 47106(c)(1)(A)(ii), which allows communities affected by those projects to petition the Secretary if the community does not have voting representation on the airport’s managing board. Although the petition procedure has been used only infrequently, the FAA determined that it would be helpful to provide the public with guidance on the procedures for filing a petition. In addition to setting out the procedural requirements for submitting a petition, the FAA’s proposal provides that the right of petition only applies to the community in which the project will be physically located or where there are significant impacts. The FAA is accepting comments on the proposed procedures for 60 days.
On March 9, 2015, the Supreme Court announced its decision in Perez v. Mortgage Banker’s Assn., holding that an administrative agency does not have to go through notice-and-comment rulemaking procedures to promulgate an interpretive rule that differs significantly from previous interpretations. The decision reversed nearly 20 years of precedent from the Court of Appeals for the District of Columbia under the so-called Paralyzed Veterans doctrine which held that new interpretive rules that changed the substance of prior rules were required to follow notice and comment procedures on the theory that a new interpretive rule was the same as a new substantive rule. See Paralyzed Veterans of America v. D.C. Arena L.P., 117 F. 3d 579 (D.C. Cir. 1997).
A unanimous Supreme Court overturned the Paralyzed Veterans doctrine, finding that Section 4 of the Administrative Procedures Act "specifically exempts interpretive rules from the notice-and-comment requirements that apply to legislative rules." The Court stated that the Paralyzed Veterans doctrine was a "judge-made procedural right" that was contrary to a plain reading of Section 4.
It is important to note that Mortgage Bankers declined to address the definition of "interpretive rule," leaving untouched the broad discretion of an agency to determine whether a rule is interpretive or legislative under current law.
The impact of this case on airports could be significant, and has been widely interpreted to expand executive administrative authority and reduce transparency in the rulemaking process. The FAA subjects relatively few of its actions to formal notice-and-comment rulemaking and instead prefers to issue policy documents, opinions, guidance letters, advisory circulars and internal orders which may or may not be released in draft form before becoming final. As a result of this ruling, the FAA may now significantly change its interpretation of its own regulations without a notice-and-comment period, allowing new interpretations to take effect immediately and without prior notice or vetting by stakeholders. Mortgage Bankers could allow the FAA to implement significant new policies with little or no opportunity for comment.
On July 24, 2015, the FAA released a revised version of its Order regarding Environmental Impact: Policies and Procedures, FAA Order 1050.1F, which replaces Order 1050.1E. Order 1050.1F provides direction to FAA personnel on how to prepare environmental documents in order to comply with NEPA. The FAA is also in the process of updating FAA Order 5050.4B, NEPA Implementing Instructions for Airport Actions, and the Environmental Desk Reference for Airport Actions, to reflect the changes to Order 1050.1F.
Includes sections on the environmental review appropriate for NextGen-related actions.
Clarifies the FAA’s responsibilities and the role of applicants and contractors and the role of states in the State Block Grant Program.
Clarifies which projects warrant environmental monitoring for purposes of mitigation and the type and extent of monitoring.
Adds a discussion of Environmental Management System and its application to all FAA programs, including NextGen.
Identifies actions that normally require an EA, including new actions such as the establishment or modification of an Instrument Flight Rules Military Training Route and the approval of formal and informal runway use programs that may significantly increase noise over noise sensitive areas.
Identifies actions that normally require an EIS.
Adds national marine sanctuaries and wilderness areas to the list of resources that must be considered in evaluating actions for extraordinary circumstances that would preclude the use of a CATEX for a proposed action.
Changes the CATEX process by updating the CATEX documentation requirements and adding to and amending the list of actions that ordinarily qualify for a CATEX.
Requires language in notices soliciting public comment on draft EAs and draft EISs stating that personal information provided by commentators may be made publicly available.
Explains under what conditions the FAA may terminate the preparation of an EIS.
Clarifies and expands on requirements relating to FAA adoption of other agencies’ NEPA documents.
Updates and clarifies emergency actions.
The Environmental Protection Agency (EPA) and the Army Corps of Engineers (CORPs) recently issued a new rule defining "waters of the United States" (WOTUS) under the Clean Water Act (CWA). The Rule will become effective on August 28, 2015. The purpose of the Rule is to codify historical and current agency practices in determining which waters and wetlands are regulated under the CWA by virtue of being "waters of the United States." After years of uncertainty and extensive litigation over the meaning and scope of WOTUS, the Rule is intended to establish definitive categories of WOTUS and provide clarity and predictability in determining jurisdictional waters.
The EPA and Corps state that Rule narrows the scope of the existing definition of WOTUS—and therefore limits the scope of waters regulated under the CWA—due to new explicit limitations on certain waters. The Rule establishes jurisdiction for two types of waters: 1) waters that are always jurisdictional, such as interstate waters, and 2) a narrower category of waters that require a case-specific analysis to determine whether they have a significant nexus to other WOTUS. The Rule also includes bright line, geographic boundaries for certain waters that are intended to simplify a WOTUS determination.
The Rule newly codifies multiple exclusions to CWA jurisdiction. The former rule only expressly excluded waste treatment systems and prior converted cropland from WOTUS. The new Rule adds, among others, exclusions for stormwater control features constructed in dry land, ditches that are not a relocated tributary or excavated in a tributary, and artificial lakes and ponds constructed in dry lands. Also, for the first time, groundwater is expressly excluded from the definition of WOTUS.
Whether the Rule results in significant changes in the scope of CWA jurisdiction will be played out through its practical application in the field and through litigation in the courts. 27 states filed legal challenges to the Rule within two days of the Rule’s June 29, 2015 publication in the Federal Register, and a coalition of industry and trade groups filed an additional challenge shortly thereafter.
If upheld by the courts, the new regulations should ease permitting requirements for airport projects that require construction or modification of storm water control features, retention ponds, and similar facilities that are excluded from permitting requirements under the new regulations.
