                          Subpart A--General Provisions

 Sec. 161.1   Purpose.

   This part implements the Airport Noise and Capacity Act of 1990 (49 U.S.C.
 App. 2153, 2154, 2155, and 2156). It prescribes:
   (a) Notice requirements and procedures for airport operators implementing
 Stage 3 aircraft noise and access restrictions pursuant to agreements between
 airport operators and aircraft operators;
   (b) Analysis and notice requirements for airport operators proposing Stage
 2 aircraft noise and access restrictions;
   (c) Notice, review, and approval requirements for airport operators
 proposing Stage 3 aircraft noise and access restrictions; and
   (d) Procedures for Federal Aviation Administration reevaluation of
 agreements containing restrictions on Stage 3 aircraft operations and of
 aircraft noise and access restrictions affecting Stage 3 aircraft operations
 imposed by airport operators.

 Sec. 161.3   Applicability.

   (a) This part applies to airports imposing restrictions on Stage 2 aircraft
 operations proposed after October 1, 1990, and to airports imposing
 restrictions on Stage 3 aircraft operations that became effective after
 October 1, 1990.
   (b) This part also applies to airports enacting amendments to airport noise
 and access restrictions in effect on October 1, 1990, but amended after that
 date, where the amendment reduces or limits aircraft operations or affects
 aircraft safety.
   (c) The notice, review, and approval requirements set forth in this part
 apply to all airports imposing noise or access restrictions as defined in
 Sec. 161.5 of this part.

 Sec. 161.5  Definitions.

   For the purposes of this part, the following definitions apply:
   Agreement means a document in writing signed by the airport operator; those
 aircraft operators currently operating at the airport that would be affected
 by the noise or access restriction; and all affected new entrants planning to
 provide new air service within 180 days of the effective date of the
 restriction that have submitted to the airport operator a plan of operations
 and notice of agreement to the restriction.
   Aircraft operator, for purposes of this part, means any owner of an
 aircraft that operates the aircraft, i.e., uses, causes to use, or authorizes
 the use of the aircraft; or in the case of a leased aircraft, any lessee that
 operates the aircraft pursuant to a lease. As used in this part, aircraft
 operator also means any representative of the aircraft owner, or in the case
 of a leased aircraft, any representative of the lessee empowered to enter
 into agreements with the airport operator regarding use of the airport by an
 aircraft.
   Airport means any area of land or water, including any heliport, that is
 used or intended to be used for the landing and takeoff of aircraft, and any
 appurtenant areas that are used or intended to be used for airport buildings
 or other airport facilities or rights-of-way, together with all airport
 buildings and facilities located thereon.
   Airport noise study area means that area surrounding the airport within the
 noise contour selected by the applicant for study and must include the noise
 contours required to be developed for noise exposure maps specified in 14 CFR
 part 150.
   Airport operator means the airport proprietor.
   Aviation user class means the following categories of aircraft operators:
 air carriers operating under parts 121 or 129 of this chapter; commuters and
 other carriers operating under parts 127 and 135 of this chapter; general
 aviation, military, or government operations.
   Day-night average sound level (DNL) means the 24-hour average sound level,
 in decibels, for the period from midnight to midnight, obtained after the
 addition of ten decibels to sound levels for the periods between midnight and
 7 a.m., and between 10 p.m. and midnight, local time, as defined in 14 CFR
 part 150. (The scientific notation for DNL is Ldn).
   Noise or access restrictions means restrictions (including but not limited
 to provisions of ordinances and leases) affecting access or noise that affect
 the operations of Stage 2 or Stage 3 aircraft, such as limits on the noise
 generated on either a single-event or cumulative basis; a limit, direct or
 indirect, on the total number of Stage 2 or Stage 3 aircraft operations; a
 noise budget or noise allocation program that includes Stage 2 or Stage 3
 aircraft; a restriction imposing limits on hours of operations; a program of
 airport-use charges that has the direct or indirect effect of controlling
 airport noise; and any other limit on Stage 2 or Stage 3 aircraft that has
 the effect of controlling airport noise. This definition does not include
 peak-period pricing programs where the objective is to align the number of
 aircraft operations with airport capacity.
   Stage 2 aircraft means an aircraft that has been shown to comply with the
 Stage 2 requirements under 14 CFR part 36.
   Stage 3 aircraft means an aircraft that has been shown to comply with the
 Stage 3 requirements under 14 CFR part 36.

 Sec. 161.7   Limitations.

   (a) Aircraft operational procedures that must be submitted for adoption by
 the FAA, such as preferential runway use, noise abatement approach and
 departure procedures and profiles, and flight tracks, are not subject to this
 part. Other noise abatement procedures, such as taxiing and engine runups,
 are not subject to this part unless the procedures imposed limit the total
 number of Stage 2 or Stage 3 aircraft operations, or limit the hours of Stage
 2 or Stage 3 aircraft operations, at the airport.
   (b) The notice, review, and approval requirements set forth in this part do
 not apply to airports with restrictions as specified in 49 U.S.C. App.
 2153(a)(2)(C):
   (1) A local action to enforce a negotiated or executed airport aircraft
 noise or access agreement between the airport operator and the aircraft
 operator in effect on November 5, 1990.
   (2) A local action to enforce a negotiated or executed airport aircraft
 noise or access restriction the airport operator and the aircraft operators
 agreed to before November 5, 1990.
   (3) An intergovernmental agreement including airport aircraft noise or
 access restriction in effect on November 5, 1990.
   (4) A subsequent amendment to an airport aircraft noise or access agreement
 or restriction in effect on November 5, 1990, where the amendment does not
 reduce or limit aircraft operations or affect aircraft safety.
   (5) A restriction that was adopted by an airport operator on or before
 October 1, 1990, and that was stayed as of October 1, 1990, by a court order
 or as a result of litigation, if such restriction, or a part thereof, is
 subsequently allowed by a court to take effect.
   (6) In any case in which a restriction described in paragraph (b)(5) of
 this section is either partially or totally disallowed by a court, any new
 restriction imposed by an airport operator to replace such disallowed
 restriction, if such new restriction would not prohibit aircraft operations
 in effect on November 5, 1990.
   (7) A local action that represents the adoption of the final portion of a
 program of a staged airport aircraft noise or access restriction, where the
 initial portion of such program was adopted during calendar year 1988 and was
 in effect on November 5, 1990.
   (c) The notice, review, and approval requirements of subpart D of this part
 with regard to Stage 3 aircraft restrictions do not apply if the FAA has,
 prior to November 5, 1990, formed a working group (outside of the process
 established by 14 CFR part 150) with a local airport operator to examine the
 noise impact of air traffic control procedure changes. In any case in which
 an agreement relating to noise reductions at such airport is then entered
 into between the airport proprietor and an air carrier or air carrier
 constituting a majority of the air carrier users of such airport, the
 requirements of subparts B and D of this part with respect to restrictions on
 Stage 3 aircraft operations do apply to local actions to enforce such
 agreements.
   (d) Except to the extent required by the application of the provisions of
 the Act, nothing in this part eliminates, invalidates, or supersedes the
 following:
   (1) Existing law with respect to airport noise or access restrictions by
 local authorities;
   (2) Any proposed airport noise or access regulation at a general aviation
 airport where the airport proprietor has formally initiated a regulatory or
 legislative process on or before October 1, 1990; and
   (3) The authority of the Secretary of Transportation to seek and obtain
 such legal remedies as the Secretary considers appropriate, including
 injunctive relief.

 Sec. 161.9   Designation of noise description methods.

   For purposes of this part, the following requirements apply:
   (a) The sound level at an airport and surrounding areas, and the exposure
 of individuals to noise resulting from operations at an airport, must be
 established in accordance with the specifications and methods prescribed
 under appendix A of 14 CFR part 150; and
   (b) Use of computer models to create noise contours must be in accordance
 with the criteria prescribed under appendix A of 14 CFR part 150.


 Sec. 161.11   Identification of land uses in airport noise study area.

   For the purposes of this part, uses of land that are normally compatible or
 noncompatible with various noise-exposure levels to individuals around
 airports must be identified in accordance with the criteria prescribed under
 appendix A of 14 CFR part 150. Determination of land use must be based on
 professional planning, zoning, and building and site design information and
 expertise.

   (2) Objects to the restriction.
   (b) Failure of any person described in Sec. 161.105(a) of this part to
 notify the airport operator that it objects to the proposed restriction will
 constitute waiver of the right to claim that it did not consent to the
 agreement and render that person ineligible to use lack of signature as
 ground to apply for sanctions under subpart F of this part for two years
 following the effective date of the restriction. The signature of such a
 person need not be obtained by the airport operator in order to comply with
 Sec. 161.107(a) of this part.
   (c) All other new entrants are also ineligible to use lack of signature as
 ground to apply for sanctions under subpart F of this part for two years.

 as long as the restriction is in effect. The airport operator shall make
 these materials available for inspection upon request by the FAA. The
 information shall be made available for inspection by any person during the
 pendency of any petition for reevaluation found justified by the FAA.


 Sec. 161.113  Effect of agreements; limitation on reevaluation.

   (a) Except as otherwise provided in this subpart, a restriction implemented
 by an airport operator pursuant to this subpart shall have the same force and
 effect as if it had been a restriction implemented in accordance with subpart
 D of this part.
   (b) A restriction implemented by an airport operator pursuant to this
 subpart may be subject to reevaluation by the FAA under subpart E of this
 part.

 comply with this subpart, the operator shall:
   (1) Ensure that all parties identified for direct notice under Sec.
 161.203(b) are notified that the airport's 14 CFR part 150 program will
 include a proposed Stage 2 restriction under part 161, and that these parties
 are offered the opportunity to participate as consulted parties during the
 development of the 14 CFR part 150 program;
   (2) Provide the FAA with a full text of the proposed restriction, including
 any sanctions for noncompliance, at the time of the notice;
   (3) Include the information in Sec. 161.203 (c)(2) through (c)(5) and
 161.205 in the analysis of the proposed restriction for the part 14 CFR part
 150 program;
   (4) Wait 180 days following the availability of the above analysis for
 review by the consulted parties and compliance with the above notice
 requirements before implementing the Stage 2 restriction; and
   (5) Include in its 14 CFR part 150 submission to the FAA evidence of
 compliance with paragraphs (b)(1) and (b)(4) of this section, and the
 analysis in paragraph (b)(3) of this section, together with a clear
 identification that the 14 CFR part 150 program includes a proposed Stage 2
 restriction under part 161.
   (c) The FAA determination on the 14 CFR part 150 submission does not
 constitute approval or disapproval of the proposed Stage 2 restriction under
 part 161.
   (d) An amendment of a restriction may also be processed under 14 CFR part
 150 procedures in accordance with this section.


 Sec. 161.213  Notification of a decision not to implement a restriction.

   If a proposed restriction has been through the procedures prescribed in
 this subpart and the restriction is not subsequently implemented, the airport
 operator shall so advise the interested parties. Interested parties are
 described in Sec. 161.209(a).

           Subpart D--Notice, Review, and Approval Requirements for
                             Stage 3 Restrictions

 Sec. 161.301  Scope.

   (a) This subpart applies to:
   (1) An airport imposing a noise or access restriction on the operation of
 Stage 3 aircraft that first became effective after October 1, 1990.
   (2) An airport imposing an amendment to a Stage 3 restriction, if the
 amendment becomes effective after October 1, 1990, and reduces or limits
 Stage 3 aircraft operations (compared to the restriction that it amends) or
 affects aircraft safety.
   (b) This subpart does not apply to an airport imposing a Stage 3
 restriction specifically exempted in Sec. 161.7, or an agreement complying
 with subpart B of this part.
   (c) A Stage 3 restriction within the scope of this subpart may not become
 effective unless it has been submitted to and approved by the FAA. The FAA
 will review only those Stage 3 restrictions that are proposed by, or on

 not included with the notice); and
   (9) The address for submitting comments to the airport operator or aircraft
 operator proposing the restriction, including identification of a contact
 person.
   (d) Applicants may propose alternative restrictions, including partial
 implementation of any proposal, and indicate an order of preference. If
 alternative restriction proposals are submitted, the requirements listed in
 paragraphs (c)(2) through (c)(6) of this section should address the
 alternative proposals where appropriate.

 Sec. 161.305  Required analysis and conditions for approval of proposed
     restrictions.

   Each applicant proposing a noise or access restriction on Stage 3
 operations shall prepare and make available for public comment an analysis
 that supports, by substantial evidence, that the six statutory conditions for
 approval have been met for each restriction and any alternatives submitted.
 The statutory conditions are set forth in 49 U.S.C. App. 2153(d)(2) and
 paragraph (e) of this section. Any proposed restriction (including
 alternatives) on Stage 3 aircraft operations that also affects the operation
 of Stage 2 aircraft must include analysis of the proposals in a manner that
 permits the proposal to be understood in its entirety. (Nothing in this
 section is intended to add a requirement for the issuance of restrictions on
 Stage 2 aircraft to those of subpart C of this part.) The applicant shall
 provide:
   (a) The complete text of the proposed restriction and any submitted
 alternatives, including the proposed wording in a city ordinance, airport
 rule, lease, or other document, and any sanctions for noncompliance;
   (b) Maps denoting the airport geographic boundary, and the geographic
 boundaries and names of each jurisdiction that controls land use within the
 airport noise study area;
   (c) An adequate environmental assessment of the proposed restriction or
 adequate information supporting a categorical exclusion in accordance with
 FAA orders and procedures regarding compliance with the National
 Environmental Policy Act of 1969 (42 U.S.C. 4321);
   (d) A summary of the evidence in the submission supporting the six
 statutory conditions for approval; and
   (e) An analysis of the restriction, demonstrating by substantial evidence
 that the statutory conditions are met. The analysis must:
   (1) Be sufficiently detailed to allow the FAA to evaluate the merits of the
 proposed restriction; and
   (2) Contain the following essential elements needed to provide substantial
 evidence supporting each condition for approval:
   (i) Condition 1: The restriction is reasonable, nonarbitrary, and
 nondiscriminatory. (A) Essential information needed to demonstrate this
 condition includes the following:
   (1) Evidence that a current or projected noise or access problem exists,
 and that the proposed action(s) could relieve the problem, including:
   (i) A detailed description of the problem precipitating the proposed
 restriction with relevant background information on factors contributing to
 the proposal and any court-ordered action or estimated liability concerns; a
 description of any noise agreements or noise or access restrictions currently
 in effect at the airport; and measures taken to achieve land-use
 compatibility, such as controls or restrictions on land use in the vicinity
 of the airport and measures carried out in response to 14 CFR part 150; and
 actions taken to comply with grant assurances requiring that:
   (A) Airport development projects be reasonably consistent with plans of
 public agencies that are authorized to plan for the development of the area
 around the airport; and
   (B) The sponsor give fair consideration to the interests of communities in
 or near where the project may be located; take appropriate action, including
 the adoption of zoning laws, to the extent reasonable, to restrict the use of
 land near the airport to activities and purposes compatible with normal
 airport operations; and not cause or permit any change in land use, within
 its jurisdiction, that will reduce the compatibility (with respect to the
 airport) of any noise compatibility program measures upon which federal funds
 have been expended.
   (ii) An analysis of the estimated noise impact of aircraft operations with
 and without the proposed restriction for the year the restriction is expected
 to be implemented, for a forecast timeframe after implementation, and for any
 other years critical to understanding the noise impact of the proposed
 restriction. The analysis of noise impact with and without the proposed
 restriction including:
   (A) Maps of the airport noise study area overlaid with noise contours as
 specified in Secs. 161.9 and 161.11 of this part;
   (B) The number of people and the noncompatible land uses within the airport
 noise study area with and without the proposed restriction for each year the
 noise restriction is analyzed;
   (C) Technical data supporting the noise impact analysis, including the
 classes of aircraft, fleet mix, runway use percentage, and day/night breakout
 of operations; and
   (D) Data on current and projected airport activity that would exist in the
 absence of the proposed restriction.
   (2) Evidence that other available remedies are infeasible or would be less
 cost-effective, including descriptions of any alternative aircraft
 restrictions that have been considered and rejected, and the reasons for the
 rejection; and of any land use or other nonaircraft controls or restrictions
 that have been considered and rejected, including those proposed under 14 CFR
 part 150 and not implemented, and the reasons for the rejection or failure to
 implement.
   (3) Evidence that the noise or access standards are the same for all
 aviation user classes or that the differences are justified, such as:
   (i) A description of the relationship of the effect of the proposed
 restriction on airport users (by aviation user class); and
   (ii) The noise attributable to these users in the absence of the proposed
 restriction.
   (B) At the applicant's discretion, information may also be submitted as
 follows:
   (1) Evidence not submitted under paragraph (e)(2)(ii)(A) of this section
 (Condition 2) that there is a reasonable chance that expected benefits will
 equal or exceed expected cost; for example, comparative economic analyses of
 the costs and benefits of the proposed restriction and aircraft and
 nonaircraft alternative measures. For detailed elements of analysis, see
 paragraph (e)(2)(ii)(A) of this section.
   (2) Evidence not submitted under paragraph (e)(2)(ii)(A) of this section
 that the level of any noise-based fees that may be imposed reflects the cost
 of mitigating noise impacts produced by the aircraft, or that the fees are
 reasonably related to the intended level of noise impact mitigation.
   (ii) Condition 2: The restriction does not create an undue burden on
 interstate or foreign commerce. (A) Essential information needed to
 demonstrate this statutory condition includes:
   (1) Evidence, based on a cost-benefit analysis, that the estimated
 potential benefits of the restriction have a reasonable chance to exceed the
 estimated potential cost of the adverse effects on interstate and foreign
 commerce. In preparing the economic analysis required by this section, the
 applicant shall use currently accepted economic methodology, specify the
 methods used and assumptions underlying the analysis, and consider:
   (i) The effect of the proposed restriction on operations of aircraft by
 aviation user class (and for air carriers, the number of operations of
 aircraft by carrier), and on the volume of passengers and cargo for the year
 the restriction is expected to be implemented and for the forecast timeframe.
   (ii) The estimated costs of the proposed restriction and alternative
 nonaircraft restrictions including the following, as appropriate:
   (A) Any additional cost of continuing aircraft operations under the
 restriction, including reasonably available information concerning any net
 capital costs of acquiring or retrofitting aircraft (net of salvage value and
 operating efficiencies) by aviation user class; and any incremental recurring
 costs;
   (B) Costs associated with altered or discontinued aircraft operations, such
 as reasonably available information concerning loss to carriers of operating
 profits; decreases in passenger and shipper consumer surplus by aviation user
 class; loss in profits associated with other airport services or other
 entities: and/or any significant economic effect on parties other than
 aviation users.
   (C) Costs associated with implementing nonaircraft restrictions or
 nonaircraft components of restrictions, such as reasonably available
 information concerning estimates of capital costs for real property,
 including redevelopment, soundproofing, noise easements, and purchase of
 property interests; and estimates of associated incremental recurring costs;
 or an explanation of the legal or other impediments to implementing such
 restrictions.
   (D) Estimated benefits of the proposed restriction and alternative
 restrictions that consider, as appropriate, anticipated increase in real
 estate values and future construction cost (such as sound insulation)
 savings; anticipated increase in airport revenues; quantification of the
 noise benefits, such as number of people removed from noise contours and
 improved work force and/or educational productivity, if any; valuation of
 positive safety effects, if any; and/or other qualitative benefits, including
 improvements in quality of life.
   (B) At the applicant's discretion, information may also be submitted as
 follows:
   (1) Evidence that the affected carriers have a reasonable chance to
 continue service at the airport or at other points in the national airport
 system.
   (2) Evidence that other air carriers are able to provide adequate service
 to the airport and other points in the system without diminishing
 competition.
   (3) Evidence that comparable services or facilities are available at
 another airport controlled by the airport operator in the market area,
 including services available at other airports.
   (4) Evidence that alternative transportation service can be attained
 through other means of transportation.
   (5) Information on the absence of adverse evidence or adverse comments with
 respect to undue burden in the notice process required in Sec. 161.303, or
 alternatively in Sec. 161.321, of this part as evidence that there is no
 undue burden.
   (iii) Condition 3: The proposed restriction maintains safe and efficient
 use of the navigable airspace. Essential information needed to demonstrate
 this statutory condition includes evidence that the proposed restriction
 maintains safe and efficient use of the navigable airspace based upon:
   (A) Identification of airspace and obstacles to navigation in the vicinity
 of the airport; and
   (B) An analysis of the effects of the proposed restriction with respect to
 use of airspace in the vicinity of the airport, substantiating that the
 restriction maintains or enhances safe and efficient use of the navigable
 airspace. The analysis shall include a description of the methods and data
 used.
   (iv) Condition 4: The proposed restriction does not conflict with any
 existing Federal statute or regulation. Essential information needed to
 demonstrate this condition includes evidence demonstrating that no conflict
 is presented between the proposed restriction and any existing Federal
 statute or regulation, including those governing:
   (A) Exclusive rights;
   (B) Control of aircraft operations; and
   (C) Existing Federal grant agreements.
   (v) Condition 5: The applicant has provided adequate opportunity for public
 comment on the proposed restriction. Essential information needed to
 demonstrate this condition includes evidence that there has been adequate
 opportunity for public comment on the restriction as specified in Sec.
 161.303 or Sec. 161.321 of this part.
   (vi) Condition 6: The proposed restriction does not create an undue burden
 on the national aviation system. Essential information needed to demonstrate
 this condition includes evidence that the proposed restriction does not
 create an undue burden on the national aviation system such as:
   (A) An analysis demonstrating that the proposed restriction does not have a
 substantial adverse effect on existing or planned airport system capacity, on
 observed or forecast airport system congestion and aircraft delay, and on
 airspace system capacity or workload;
   (B) An analysis demonstrating that nonaircraft alternative measures to
 achieve the same goals as the proposed subject restrictions are
 inappropriate;
   (C) The absence of comments with respect to imposition of an undue burden
 on the national aviation system in response to the notice required in Sec.
 161.303 or Sec. 161.321.


 Sec. 161.307  Comment by interested parties.

   (a) Each applicant proposing a restriction shall establish a public docket
 or similar method for receiving and considering comments, and shall make
 comments available for inspection by interested parties upon request.
 Comments must be retained as long as the restriction is in effect.
   (b) Each applicant shall submit to the FAA a summary of any comments
 received. Upon request by the FAA, the applicant shall submit copies of the
 comments.


 Sec. 161.309  Requirements for proposal changes.

   (a) Each applicant shall promptly advise interested parties of any changes
 to a proposed restriction or alternative restriction that are not encompassed
 in the proposals submitted, including changes that affect noncompatible land
 uses or that take place before the effective date of the restriction, and
 make available these changes to the proposed restriction and its analysis.
 For the purpose of this paragraph, interested parties include those who
 received direct notice under Sec. 161.303(b) of this part, or those who were
 required to be consulted in accordance with the procedures in Sec. 161.321 of
 this part, and those who commented on the proposed restriction.
   (b) If there are substantial changes to a proposed restriction or the
 analysis made available prior to the effective date of the restriction, the
 applicant proposing the restriction shall initiate new notice in accordance
 with the procedures in Sec. 161.303 or, alternatively, the procedures in Sec.
 161.321. These requirements apply to substantial changes that are not
 encompassed in submitted alternative restriction proposals and their
 analyses. A substantial change to a restriction includes, but is not limited
 to, any proposal that would increase the burden on any aviation user class.
   (c) In addition to the information in Sec. 161.303(c), a new notice must
 indicate that the applicant is revising a previous notice, provide the reason
 for making the revision, and provide a new effective date (if any) for the
 restriction.
   (d) If substantial changes requiring a new notice are made during the FAA's
 180-day review of the proposed restriction, the applicant submitting the
 proposed restriction shall notify the FAA in writing that it is withdrawing
 its proposal from the review process until it has completed additional
 analysis, public review, and documentation of the public review. Resubmission
 to the FAA will restart the 180-day review.


 Sec. 161.311  Application procedure for approval of proposed restriction.

   Each applicant proposing a Stage 3 restriction shall submit to the FAA the
 following information for each restriction and alternative restriction
 submitted, with a request that the FAA review and approve the proposed Stage
 3 noise or access restriction:
   (a) A summary of evidence of the fulfillment of conditions for approval, as
 specified in Sec. 161.305;
   (b) An analysis as specified in Sec. 161.305, as appropriate to the
 proposed restriction;
   (c) A statement that the entity submitting the proposal is the party
 empowered to implement the restriction, or is submitting the proposal on
 behalf of such party; and
   (d) A statement as to whether the airport requests, in the event of
 disapproval of the proposed restriction or any alternatives, that the FAA
 approve any portion of the restriction or any alternative that meets the
 statutory requirements for approval. An applicant requesting partial approval
 of any proposal should indicate its priorities as to portions of the proposal
 to be approved.



 Sec. 161.313  Review of application.

   (a) Determination of completeness. The FAA, within 30 days of receipt of an
 application, will determine whether the application is complete in accordance
 with Sec. 161.311. Determinations of completeness will be made on all
 proposed restrictions and alternatives. This completeness determination is
 not an approval or disapproval of the proposed restriction.
   (b) Process for complete application. When the FAA determines that a
 complete application has been submitted, the following procedures apply:
   (1) The FAA notifies the applicant that it intends to act on the proposed
 restriction and publishes notice of the proposed restriction in the Federal
 Register in accordance with Sec. 161.315. The 180-day period for approving or
 disapproving the proposed restriction will start on the date of original FAA
 receipt of the application.
   (2) Following review of the application, public comments, and any other
 information obtained under Sec. 161.317(b), the FAA will issue a decision
 approving or disapproving the proposed restriction. This decision is a final
 decision of the Administrator for purpose of judicial review.
   (c) Process for incomplete application. If the FAA determines that an
 application is not complete with respect to any submitted restriction or
 alternative restriction, the following procedures apply:
   (1) The FAA shall notify the applicant in writing, returning the
 application and setting forth the type of information and analysis needed to
 complete the application in accordance with Sec. 161.311.
   (2) Within 30 days after the receipt of this notice, the applicant shall
 advise the FAA in writing whether or not it intends to resubmit and
 supplement its application.
   (3) If the applicant does not respond in 30 days, or advises the FAA that
 it does not intend to resubmit and/or supplement the application, the
 application will be denied. This closes the matter without prejudice to later
 application and does not constitute disapproval of the proposed restriction.
   (4) If the applicant chooses to resubmit and supplement the application,
 the following procedures apply:
   (i) Upon receipt of the resubmitted application, the FAA determines whether
 the application, as supplemented, is complete as set forth in paragraph (a)
 of this section.
   (ii) If the application is complete, the procedures set forth in Sec.
 161.315 shall be followed. The 180-day review period starts on the date of
 receipt of the last supplement to the application.
   (iii) If the application is still not complete with respect to the proposed
 restriction or at least one submitted alternative, the FAA so advises the
 applicant as set forth in paragraph (c)(1) of this section and provides the
 applicant with an additional opportunity to supplement the application as set
 forth in paragraph (c)(2) of this section.
   (iv) If the environmental documentation (either an environmental assessment
 or information supporting a categorical exclusion) is incomplete, the FAA
 will so notify the applicant in writing, returning the application and
 setting forth the types of information and analysis needed to complete the
 documentation. The FAA will continue to return an application until adequate
 environmental documentation is provided. When the application is determined
 to be complete, including the environmental documentation, the 180-day period
 for approval or disapproval will begin upon receipt of the last supplement to
 the application.
   (v) Following review of the application and its supplements, public
 comments, and any other information obtained under Sec. 161.317(b), the FAA
 will issue a decision approving or disapproving the application. This
 decision is a final decision of the Administrator for the purpose of judicial
 review.
   (5) The FAA will deny the application and return it to the applicant if:
   (i) None of the proposals submitted are found to be complete;
   (ii) The application has been returned twice to the applicant for reasons
 other than completion of the environmental documentation; and
   (iii) The applicant declines to complete the application. This closes the
 matter without prejudice to later application, and does not constitute
 disapproval of the proposed restriction.


 Sec. 161.315  Receipt of complete application.

   (a) When a complete application has been received, the FAA will notify the
 applicant by letter that the FAA intends to act on the application.
   (b) The FAA will publish notice of the proposed restriction in the Federal
 Register, inviting interested parties to file comments on the application
 within 30 days after publication of the Federal Register notice.


 Sec. 161.317  Approval or disapproval of proposed restriction.

   (a) Upon determination that an application is complete with respect to at
 least one of the proposals submitted by the applicant, the FAA will act upon
 the complete proposals in the application. The FAA will not act on any
 proposal for which the applicant has declined to submit additional necessary
 information.
   (b) The FAA will review the applicant's proposals in the preference order
 specified by the applicant. The FAA may request additional information from
 aircraft operators, or any other party, and may convene an informal meeting
 to gather facts relevant to its determination.
   (c) The FAA will evaluate the proposal and issue an order approving or
 disapproving the proposed restriction and any submitted alternatives, in
 whole or in part, in the order of preference indicated by the applicant. Once
 the FAA approves a proposed restriction, the FAA will not consider any
 proposals of lower applicant-stated preference. Approval or disapproval will
 be given by the FAA within 180 days after receipt of the application or last
 supplement thereto under Sec. 161.313. The FAA will publish its decision in
 the Federal Register and notify the applicant in writing.
   (d) The applicant's failure to provide substantial evidence supporting the
 statutory conditions for approval of a particular proposal is grounds for
 disapproval of that proposed restriction.
   (e) The FAA will approve or disapprove only the Stage 3 aspects of a
 restriction if the restriction applies to both Stage 2 and Stage 3 aircraft
 operations.
   (f) An order approving a restriction may be subject to requirements that
 the applicant:
   (1) Comply with factual representations and commitments in support of the
 restriction; and
   (2) Ensure that any environmental mitigation actions or commitments by any
 party that are set forth in the environmental documentation provided in
 support of the restriction are implemented.


 Sec. 161.319  Withdrawal or revision of restriction.

   (a) The applicant may withdraw or revise a proposed restriction at any time
 prior to FAA approval or disapproval, and must do so if substantial changes
 are made as described in Sec. 161.309. The applicant shall notify the FAA in
 writing of a decision to withdraw the proposed restriction for any reason.
 The FAA will publish a notice in the Federal Register that it has terminated
 its review without prejudice to resubmission. A resubmission will be
 considered a new application.
   (b) A subsequent amendment to a Stage 3 restriction that was in effect
 after October 1, 1990, or an amendment to a Stage 3 restriction previously
 approved by the FAA, is subject to the procedures in this subpart if the
 amendment will further reduce or limit aircraft operations or affect aircraft
 safety. The applicant may, at its option, revise or amend a restriction
 previously disapproved by the FAA and resubmit it for approval. Amendments
 are subject to the same requirements and procedures as initial submissions.


 Sec. 161.321  Optional use of 14 CFR part 150 procedures.

   (a) An airport operator may use the procedures in part 150 of this chapter,
 instead of the procedures described in Secs. 161.303(b) and 161.309(b) of
 this part, as a means of providing an adequate public notice and opportunity
 to comment on proposed Stage 3 restrictions, including submitted
 alternatives.
   (b) If the airport operator elects to use 14 CFR part 150 procedures to
 comply with this subpart, the operator shall:
   (1) Ensure that all parties identified for direct notice under Sec.
 161.303(b) are notified that the airport's 14 CFR part 150 program submission
 will include a proposed Stage 3 restriction under part 161, and that these
 parties are offered the opportunity to participate as consulted parties
 during the development of the 14 CFR part 150 program;
   (2) Include the information required in Sec. 161.303(c) (2) through (5) and
 Sec. 161.305 in the analysis of the proposed restriction in the 14 CFR part
 150 program submission; and
   (3) Include in its 14 CFR part 150 submission to the FAA evidence of
 compliance with the notice requirements in paragraph (b)(1) of this section
 and include the information required for a part 161 application in Sec.
 161.311, together with a clear identification that the 14 CFR part 150
 submission includes a proposed Stage 3 restriction for FAA review and
 approval under Secs. 161.313, 161.315, and 161.317.
   (c) The FAA will evaluate the proposed part 161 restriction on Stage 3
 aircraft operations included in the 14 CFR part 150 submission in accordance
 with the procedures and standards of this part, and will review the total 14
 CFR part 150 submission in accordance with the procedures and standards of 14
 CFR part 150.
   (d) An amendment of a restriction, as specified in Sec. 161.319(b) of this
 part, may also be processed under 14 CFR part 150 procedures.

 Sec. 161.323  Notification of a decision not to implement a restriction.

   If a Stage 3 restriction has been approved by the FAA and the restriction
 is not subsequently implemented, the applicant shall so advise the interested
 parties specified in Sec. 161.309(a) of this part.


 Sec. 161.325  Availability of data and comments on an implemented
     restriction.

   The applicant shall retain all relevant supporting data and all comments
 relating to an approved restriction for as long as the restriction is in
 effect and shall make these materials available for inspection upon request
 by the FAA. This information shall be made available for inspection by any
 person during the pendency of any petition for reevaluation found justified
 by the FAA.


                Subpart E--Reevaluation of Stage 3 Restrictions

 Sec. 161.401  Scope.

   This subpart applies to an airport imposing a noise or access restriction
 on the operation of Stage 3 aircraft that first became effective after
 October 1, 1990, and had either been agreed to in compliance with the
 procedures in Subpart B of this part or approved by the FAA in accordance
 with the procedures in subpart D of this part. This subpart does not apply to
 Stage 2 restrictions imposed by airports. This subpart does not apply to
 Stage 3 restrictions specifically exempted in Sec. 161.7.

 Sec. 161.403  Criteria for reevaluation.

   (a) A request for reevaluation must be submitted by an aircraft operator.
   (b) An aircraft operator must demonstrate to the satisfaction of the FAA
 that there has been a change in the noise environment of the affected airport
 and that a review and reevaluation pursuant to the criteria in Sec. 161.305
 is therefore justified.
   (1) A change in the noise environment sufficient to justify reevaluation is
 either a DNL change of 1.5 dB or greater (from the restriction's anticipated
 target noise level result) over noncompatible land uses, or a change of 17
 percent or greater in the noncompatible land uses, within an airport noise
 study area. For approved restrictions, calculation of change shall be based
 on the divergence of actual noise impact of the restriction from the
 estimated noise impact of the restriction predicted in the analysis required
 in Sec. 161.305(e)(2)(i)(A)(1)(ii). The change in the noise environment or in
 the noncompatible land uses may be either an increase or decrease in noise or
 in noncompatible land uses. An aircraft operator may submit to the FAA
 reasons why a change that does not fall within either of these parameters
 justifies reevaluation, and the FAA will consider such arguments on a case-
 by-case basis.
   (2) A change in the noise environment justifies reevaluation if the change
 is likely to result in the restriction not meeting one or more of the
 conditions for approval set forth in Sec. 161.305 of this part for approval.
 The aircraft operator must demonstrate that such a result is likely to occur.
   (c) A reevaluation may not occur less than 2 years after the date of the
 FAA approval. The FAA will normally apply the same 2-year requirement to
 agreements under subpart B of this part that affect Stage 3 aircraft
 operations. An aircraft operator may submit to the FAA reasons why an
 agreement under subpart B of this part should be reevaluated in less than 2
 years, and the FAA will consider such arguments on a case-by-case basis.
   (d) An aircraft operator must demonstrate that it has made a good faith
 attempt to resolve locally any dispute over a restriction with the affected
 parties, including the airport operator, before requesting reevaluation by
 the FAA. Such demonstration and certification shall document all attempts of
 local dispute resolution.

 Sec. 161.405  Request for reevaluation.

   (a) A request for reevaluation submitted to the FAA by an aircraft operator
 must include the following information:
   (1) The name of the airport and associated cities and states;
   (2) A clear, concise description of the restriction and any sanctions for
 noncompliance, whether the restriction was approved by the FAA or agreed to
 by the airport operator and aircraft operators, the date of the approval or
 agreement, and a copy of the restriction as incorporated in a local
 ordinance, airport rule, lease, or other document;
   (3) The quantified change in the noise environment using methodology
 specified in this part;
   (4) Evidence of the relationship between this change and the likelihood
 that the restriction does not meet one or more of the conditions in Sec.
 161.305;
   (5) The aircraft operator's status under the restriction (e.g., currently
 affected operator, potential new entrant) and an explanation of the aircraft
 operator's specific objection; and
   (6) A description and evidence of the aircraft operator's attempt to
 resolve the dispute locally with the affected parties, including the airport
 operator.
   (b) The FAA will evaluate the aircraft operator's submission and determine
 whether or not a reevaluation is justified. The FAA may request additional
 information from the airport operator or any other party and may convene an
 informal meeting to gather facts relevant to its determination.
   (c) The FAA will notify the aircraft operator in writing, with a copy to
 the affected airport operator, of its determination.
   (1) If the FAA determines that a reevaluation is not justified, it will
 indicate the reasons for this decision.
   (2) If the FAA determines that a reevaluation is justified, the aircraft
 operator will be notified to complete its analysis and to begin the public
 notice procedure, as set forth in this subpart.


 Sec. 161.407  Notice of reevaluation.

   (a) After receiving an FAA determination that a reevaluation is justified,
 an aircraft operator desiring continuation of the reevaluation process shall
 publish a notice of request for reevaluation in an areawide newspaper or
 newspapers that either singly or together has general circulation throughout
 the airport noise study area (or the airport vicinity for agreements where an
 airport noise study area has not been delineated); post a notice in the
 airport in a prominent location accessible to airport users and the public;
 and directly notify in writing the following parties:
   (1) The airport operator, other aircraft operators providing scheduled
 passenger or cargo service at the airport, operators of aircraft based at the
 airport, potential new entrants that are known to be interested in serving
 the airport, and aircraft operators known to be routinely providing
 nonscheduled service;
   (2) The Federal Aviation Administration;
   (3) Each Federal, State, and local agency with land-use control
 jurisdiction within the airport noise study area (or the airport vicinity for
 agreements where an airport noise study area has not been delineated);
   (4) Fixed-base operators and other airport tenants whose operations may be
 affected by the agreement or the restriction;
   (5) Community groups and business organizations that are known to be
 interested in the restriction; and
   (6) Any other party that commented on the original restriction.
   (b) Each notice provided in accordance with paragraph (a) of this section
 shall include:
   (1) The name of the airport and associated cities and states;
   (2) A clear, concise description of the restriction, including whether the
 restriction was approved by the FAA or agreed to by the airport operator and
 aircraft operators, and the date of the approval or agreement;
   (3) The name of the aircraft operator requesting a reevaluation, and a
 statement that a reevaluation has been requested and that the FAA has
 determined that a reevaluation is justified;
   (4) A brief discussion of the reasons why a reevaluation is justified;
   (5) An analysis prepared in accordance with Sec. 161.409 of this part
 supporting the aircraft operator's reevaluation request, or an announcement
 of where the analysis is available for public inspection;
   (6) An invitation to comment on the analysis supporting the proposed
 reevaluation, with a minimum 45-day comment period;
   (7) Information on how to request a copy of the analysis (if not in the
 notice); and
   (8) The address for submitting comments to the aircraft operator, including
 identification of a contact person.

 Sec. 161.409  Required analysis by reevaluation petitioner.

   (a) An aircraft operator that has petitioned the FAA to reevaluate a
 restriction shall assume the burden of analysis for the reevaluation.
   (b) The aircraft operator's analysis shall be made available for public
 review under the procedures in Sec. 161.407 and shall include the following:
   (1) A copy of the restriction or the language of the agreement as
 incorporated in a local ordinance, airport rule, lease, or other document;
   (2) The aircraft operator's status under the restriction (e.g., currently
 affected operator, potential new entrant) and an explanation of the aircraft
 operator's specific objection to the restriction;
   (3) The quantified change in the noise environment using methodology
 specified in this part;
   (4) Evidence of the relationship between this change and the likelihood
 that the restriction does not meet one or more of the conditions in Sec.
 161.305; and
   (5) Sufficient data and analysis selected from Sec. 161.305, as applicable
 to the restriction at issue, to support the contention made in paragraph
 (b)(4) of this section. This is to include either an adequate environmental
 assessment of the impacts of discontinuing all or part of a restriction in
 accordance with the aircraft operator's petition, or adequate information
 supporting a categorical exclusion under FAA orders implementing the National
 Environmental Policy Act of 1969 (42 U.S.C. 4321).
   (c) The amount of analysis may vary with the complexity of the restriction,
 the number and nature of the conditions in Sec. 161.305 that are alleged to
 be unsupported, and the amount of previous analysis developed in support of
 the restriction. The aircraft operator may incorporate analysis previously
 developed in support of the restriction, including previous environmental
 documentation to the extent applicable. The applicant is responsible for
 providing substantial evidence, as described in Sec. 161.305, that one or
 more of the conditions are not supported.


 Sec. 161.411  Comment by interested parties.

   (a) Each aircraft operator requesting a reevaluation shall establish a
 docket or similar method for receiving and considering comments and shall
 make comments available for inspection to interested parties specified in
 paragraph (b) of this section upon request. Comments must be retained for two
 years.
   (b) Each aircraft operator shall promptly notify interested parties if it
 makes a substantial change in its analysis that affects either the costs or
 benefits analyzed, or the criteria in Sec. 161.305, differently from the
 analysis made available for comment in accordance with Sec. 161.407.
 Interested parties include those who received direct notice under paragraph
 (a) of Sec. 161.407 and those who have commented on the reevaluation. If an
 aircraft operator revises its analysis, it shall make the revised analysis
 available to an interested party upon request and shall extend the comment
 period at least 45 days from the date the revised analysis is made available.


 Sec. 161.413  Reevaluation procedure.

   (a) Each aircraft operator requesting a reevaluation shall submit to the
 FAA:
   (1) The analysis described in Sec. 161.409;
   (2) Evidence that the public review process was carried out in accordance
 with Secs. 161.407 and 161.411, including the aircraft operator's summary of
 the comments received; and
   (3) A request that the FAA complete a reevaluation of the restriction and
 issue findings.
   (b) Following confirmation by the FAA that the aircraft operator's
 documentation is complete according to the requirements of this subpart, the
 FAA will publish a notice of reevaluation in the Federal Register and provide
 for a 45-day comment period during which interested parties may submit
 comments to the FAA. The FAA will specifically solicit comments from the
 affected airport operator and affected local governments. A submission that
 is not complete will be returned to the aircraft operator with a letter
 indicating the deficiency, and no notice will be published. No further action
 will be taken by the FAA until a complete submission is received.
   (c) The FAA will review all submitted documentation and comments pursuant
 to the conditions of Sec. 161.305. To the extent necessary, the FAA may
 request additional information from the aircraft operator, airport operator,
 and others known to have information material to the reevaluation, and may
 convene an informal meeting to gather facts relevant to a reevaluation
 finding.


 Sec. 161.415  Reevaluation action.

   (a) Upon completing the reevaluation, the FAA will issue appropriate orders
 regarding whether or not there is substantial evidence that the restriction
 meets the criteria in Sec. 161.305 of this part.
   (b) If the FAA's reevaluation confirms that the restriction meets the
 criteria, the restriction may remain as previously agreed to or approved. If
 the FAA's reevaluation concludes that the restriction does not meet the
 criteria, the FAA will withdraw a previous approval of the restriction issued
 under subpart D of this part to the extent necessary to bring the restriction
 into compliance with this part or, with respect to a restriction agreed to
 under subpart B of this part, the FAA will specify which criteria are not
 met.
   (c) The FAA will publish a notice of its reevaluation findings in the
 Federal Register and notify in writing the aircraft operator that petitioned
 the FAA for reevaluation and the affected airport operator.


 Sec. 161.417  Notification of status of restrictions and agreements not
     meeting conditions-of-approval criteria.

   If the FAA has withdrawn all or part of a previous approval made under
 subpart D of this part, the relevant portion of the Stage 3 restriction must
 be rescinded. The operator of the affected airport shall notify the FAA of
 the operator's action with regard to a restriction affecting Stage 3 aircraft
 operations that has been found not to meet the criteria of Sec. 161.305.
 Restrictions in agreements determined by the FAA not to meet conditions for
 approval may not be enforced with respect to Stage 3 aircraft operations.


                   Subpart F--Failure to Comply With This Part

 Sec. 161.501  Scope.

   (a) This subpart describes the procedures to terminate eligibility for
 airport grant funds and authority to impose or collect passenger facility
 charges for an airport operator's failure to comply with the Airport Noise
 and Capacity Act of 1990 (49 U.S.C. App. 2151 et seq.) or this part. These
 procedures may be used with or in addition to any judicial proceedings
 initiated by the FAA to protect the national aviation system and related
 Federal interests.
   (b) Under no conditions shall any airport operator receive revenues under
 the provisions of the Airport and Airway Improvement Act of 1982 or impose or
 collect a passenger facility charge under section 1113(e) of the Federal
 Aviation Act of 1958 if the FAA determines that the airport is imposing any
 noise or access restriction not in compliance with the Airport Noise and
 Capacity Act of 1990 or this part. Recission of, or a commitment in writing
 signed by an authorized official of the airport operator to rescind or
 permanently not enforce, a noncomplying restriction will be treated by the
 FAA as action restoring compliance with the Airport Noise and Capacity Act of
 1990 or this part with respect to that restriction.


 Sec. 161.503  Informal resolution; notice of apparent violation.

   Prior to the initiation of formal action to terminate eligibility for
 airport grant funds or authority to impose or collect passenger facility
 charges under this subpart, the FAA shall undertake informal resolution with
 the airport operator to assure compliance with the Airport Noise and Capacity
 Act of 1990 or this part upon receipt of a complaint or other evidence that
 an airport operator has taken action to impose a noise or access restriction
 that appears to be in violation. This shall not preclude a FAA application
 for expedited judicial action for other than termination of airport grants
 and passenger facility charges to protect the national aviation system and
 violated federal interests. If informal resolution is not successful, the FAA
 will notify the airport operator in writing of the apparent violation. The
 airport operator shall respond to the notice in writing not later than 20
 days after receipt of the notice, and also state whether the airport operator
 will agree to defer implementation or enforcement of its noise or access
 restriction until completion of the process under this subpart to determine
 compliance.


 Sec. 161.505  Notice of proposed termination of airport grant funds and
     passenger facility charges.

   (a) The FAA begins proceedings under this section to terminate an airport
 operator's eligibility for airport grant funds and authority to impose or
 collect passenger facility charges only if the FAA determines that informal
 resolution is not successful.
   (b) The following procedures shall apply if an airport operator agrees in
 writing, within 20 days of receipt of the FAA's notice of apparent violation
 under Sec. 161.503, to defer implementation or enforcement of a noise or
 access restriction until completion of the process under this subpart to
 determine compliance.
   (1) The FAA will issue a notice of proposed termination to the airport
 operator and publish notice of the proposed action in the Federal
 Register.This notice will state the scope of the proposed termination, the
 basis for the proposed action, and the date for filing written comments or
 objections by all interested parties. This notice will also identify any
 corrective action the airport operator can take to avoid further proceedings.
 The due date for comments and corrective action by the airport operator shall
 be specified in the notice of proposed termination and shall not be less than
 60 days after publication of the notice.
   (2) The FAA will review the comments, statements, and data supplied by the
 airport operator, and any other available information, to determine if the
 airport operator has provided satisfactory evidence of compliance or has
 taken satisfactory corrective action. The FAA will consult with the airport
 operator to attempt resolution and may request additional information from
 other parties to determine compliance. The review and consultation process
 shall take not less than 30 days. If the FAA finds satisfactory evidence of
 compliance, the FAA will notify the airport operator in writing and publish
 notice of compliance in the Federal Register.
   (3) If the FAA determines that the airport operator has taken action to
 impose a noise or access restriction in violation of the Airport Noise and
 Capacity Act of 1990 or this part, the FAA will notify the airport operator
 in writing of such determination. Where appropriate, the FAA may prescribe
 corrective action, including corrective action the airport operator may still
 need to take. Within 10 days of receipt of the FAA's determination, the
 airport operator shall--
   (i) Advise the FAA in writing that it will complete any corrective action
 prescribed by the FAA within 30 days; or
   (ii) Provide the FAA with a list of the domestic air carriers and foreign
 air carriers operating at the airport and all other issuing carriers, as
 defined in Sec. 158.3 of this chapter, that have remitted passenger facility
 charge revenue to the airport in the preceding 12 months.
   (4) If the FAA finds that the airport operator has taken satisfactory
 corrective action, the FAA will notify the airport operator in writing and
 publish notice of compliance in the Federal Register. If the FAA has
 determined that the airport operator has imposed a noise or access
 restriction in violation of the Airport Noise and Capacity Act of 1990 or
 this part and satisfactory corrective action has not been taken, the FAA will
 issue an order that--
   (i) Terminates eligibility for new airport grant agreements and
 discontinues payments of airport grant funds, including payments of costs
 incurred prior to the notice; and
   (ii) Terminates authority to impose or collect a passenger facility charge
 or, if the airport operator has not received approval to impose a passenger
 facility charge, advises the airport operator that future applications for
 such approval will be denied in accordance with Sec. 158.29(a)(1)(v) of this
 chapter.
   (5) The FAA will publish notice of the order in the Federal Register and
 notify air carriers of the FAA's order and actions to be taken to terminate
 or modify collection of passenger facility charges in accordance with Sec.
 158.85(f) of this chapter.
   (c) The following procedures shall apply if an airport operator does not
 agree in writing, within 20 days of receipt of the FAA's notice of apparent
 violation under Sec. 161.503, to defer implementation or enforcement of its
 noise or access restriction until completion of the process under this
 subpart to determine compliance.
   (1) The FAA will issue a notice of proposed termination to the airport
 operator and publish notice of the proposed action in the Federal Register.
 This notice will state the scope of the proposed termination, the basis for
 the proposed action, and the date for filing written comments or objections
 by all interested parties. This notice will also identify any corrective
 action the airport operator can take to avoid further proceedings. The due
 date for comments and corrective action by the airport operator shall be
 specified in the notice of proposed termination and shall not be less than 30
 days after publication of the notice.
   (2) The FAA will review the comments, statements, and data supplied by the
 airport operator, and any other available information, to determine if the
 airport operator has provided satisfactory evidence of compliance or has
 taken satisfactory corrective action. If the FAA finds satisfactory evidence
 of compliance, the FAA will notify the airport operator in writing and
 publish notice of compliance in the Federal Register.
   (3) If the FAA determines that the airport operator has taken action to
 impose a noise or access restriction in violation of the Airport Noise and
 Capacity Act of 1990 or this part, the procedures in paragraphs (b)(3)
 through (b)(5) of this section will be followed.
