Article 3 — NOISE

(a)

As proprietor of John Wayne Airport, the County of Orange, by its Board of Supervisors, is empowered to restrict or deny the use of its Airport based upon noise considerations and finds it is in the public interest to minimize any risk of potential liability to the County of Orange for claims of damage caused by noise associated with aircraft operations at John Wayne Airport. This article reflects the intent of the Board of

Supervisors of Orange County to enact a reasonable regulatory scheme, using the legislative process, to minimize noise and any potential for damage liability, which does not unjustly discriminate between types, kinds or classes of aeronautical uses.

(b)

Any aircraft operator or person desiring to use John Wayne Airport for the purpose of commercial airline or general aviation operations shall be authorized, pursuant to this article, to engage in such use provided that all aircraft operations are in compliance with noise standards as set forth in this article and as set forth in the Phase 2 Commercial Airline Access Plan and Regulation. Consistent with the noise standards as enumerated in this article, the Board of Supervisors of Orange County does hereby grant a revocable license to use John Wayne Airport by commercial airline and general aviation aircraft as such are defined in this article.

It is the basic purpose of these rules to provide a reasonable, fair, constitutionally appropriate, and expeditious means by which persons contesting a Notice of Noise Violation imposed by the Airport Director can obtain review of the violation decision by administrative means.

To the extent this Section provides procedural processes and safeguards in excess of the minimum requirements of the United States and California Constitutions, those procedures are a courtesy only, and not an acknowledgement of any claim that this Division creates any "vested" right.

(4)

Upon receipt of the Notice of Appeal, the Airport Director shall promptly take the following actions:

(i)

The Airport Director shall review the Notice of Appeal and its contents and determine whether to (a) grant the relief requested in the Notice of Appeal; (b) modify the violation; or (c) uphold the violation and refer the

matter to the Airport Noise Violation Committee for hearing, if a hearing has been requested on the matter; and

(ii)

The Airport Director shall give written notice to the person requesting review of his decisions and determinations not later than forty-five (45) days after his receipt of the Notice of Appeal.

(e)

Referral To The Airport Noise Violation Committee. If the Airport Director determines that the County should refer the Notice of Appeal, in whole or in part, to the Airport Noise Violation Committee, pursuant to Section 2-1-30.13(d)(4)(i)(c), then, within thirty (30) days of the Committee's receipt of the Notice of Appeal, the Committee shall give written notice to the party requesting review of the date of the hearing at which the matter will be heard.

(f)

Hearing.

(1)

Rules of evidence. The hearing need not be conducted according to the technical rules relating to evidence set forth in the California Evidence Code. Any relevant evidence shall be admitted if it is the sort of evidence on which responsible persons are accustomed to rely in the conduct of serious affairs, regardless of the existence of any common law or statutory rule which might make improper the admission of such evidence over objection in civil actions. The rules of privilege shall be effective to the same extent that they are recognized in civil actions and irrelevant and unduly repetitious evidence may be excluded by the Airport Noise Violation Committee.

(2)

Determination. The Airport Noise Violation Committee shall determine, based upon all the evidence presented, whether said Notice of Violation and/or the penalty or sanction imposed should be upheld or revoked. The decision shall be supported by appropriate findings on all material issues raised at the hearing.

(g)

Decision.
