§ 16.43.050. Cumulative noise limits and noise budgets.

A.

It is the goal of the City that Incompatible Property in the vicinity of the Airport shall not be exposed to noise above sixty-five (65) CNEL. In determining compliance with this noise goal and with the noise budgets established by this Chapter, a tolerance of one (1) dB CNEL will be applied. In assessing cumulative noise levels for any period less than one (1) year, the Airport Manager shall take into consideration and allow for reasonably anticipated seasonal variations in Operations and noise. The noise of military and Public Aircraft, for which the City bears no liability, will be excluded in calculating CNEL and in assessing compliance with the CNEL goal and CNEL budgets set forth in this Chapter.

B.

For purposes of this Section, users of the Airport shall be categorized as follows: Air Carriers, Commuter Carriers, Industrial operators, Charter operators, and General Aviation (which includes all other users). Each user group at the Airport will be assigned a noise budget for takeoff and landing noise on Runway 30/12.

C.

Initial noise budgets hereunder for Air Carriers, Commuter Carriers, Charter operators, and General Aviation shall be established determining the actual monitored noise level of each user group for the twelve (12) months ended October 31, 1990. In the case of Industrial operators, the baseline November 1, 1989, to October 31, 1990, noise budget shall be established by determining the actual monitored noise level of that user group for the twelve (12) months ended October 31, 1990, as augmented to accommodate reasonably projected Operations for manufacturing and flight test purposes by aircraft types which were under design during the base year but had not yet entered service. These noise budgets are selected to comply with the provisions of the Airport Noise and Capacity Act of 1990. Noise budgets shall be established by the Airport Manager and shall be published in a Technical Appendix to this Chapter. Administrative review of the decisions of the Airport Manager under this Chapter shall be conducted pursuant to the provisions of Section 16.43.110.

D.

Following the conclusion of the first calendar quarter after the implementation of this Chapter, and following the conclusion of each calendar quarter thereafter, the Airport Manager shall issue a report assessing compliance with the noise goal set forth is Subsection A above and with the noise budgets established pursuant to Subsection C above.
