SAN DIEGO INTERNATIONAL AIRPORT – PROPOSED RUNWAY 9 DISPLACED THRESHOLD
The FAA has plans to rehabilitate the MALSR lighting station piles that extend into the Navy Boat Channel and
has released a Final Environmental Assessment 19
evaluating potential environmental effects associated with
that work. A Finding of No Significant Impact (FONSI) was issued for the rehabilitation of the MALSR lighting
station piles on June 19, 2012. 20
The changes to the MALSR system that would need to occur due to the
relocated displaced threshold would involve the relocation of some of the MALSR lights but would not result
in the relocation of piles in the Navy Boat Channel. The MALSR lights are positioned based on the landing
threshold; the relocation of the Runway 9 displaced threshold would require the relocation of the MALSR
lights, as depicted on Figure 1-5.
The relocated displaced threshold would also require the relocation of the glide slope antenna. The Runway 9
precision instrument approach would be modified to a 3.1 degree glide slope, a threshold crossing height of
55 feet, and a decision height of 250 feet with a 1/2-mile or greater visibility minimum.
1.6 Requested Federal Action
The federal actions being requested of the FAA by the SDCRAA include:
Unconditional approval of the portion of the ALP that depicts the proposed Runway 9 displaced
threshold project pursuant to 49 U.S.C. § 40103(b), 44718, and 47107(a)(16), and 14 Code of Federal
Regulations (CFR) Part 77, Objects Affecting Navigable Airspace. The ALP depicting the proposed
improvements has been processed by the FAA to determine conformance with FAA design criteria
and implications for Federal grant agreements (refer to 14 CFR Part 16). The FAA has determined that
the Proposed Action, as described in Section 1.5, is consistent with existing airspace utilization and
procedures. The ALP was evaluated under airspace case number 2012-AWP-662-NRA (Appendix A).
Determination of eligibility for federal assistance under the Federal grant-in-aid program authorized
by the Airport and Airway Improvement Act of 1982, as amended, and pursuant to 49 U.S.C. 47101 et.
seq.
Establishment of flight procedure modifications pursuant to 14 CFR Part 95, Instrument Flight Rules
(IFR) Altitudes.
Implementation of revised air traffic control procedures below 3,000 feet above ground level.
Processing of airspace changes, installation, and/or relocation of FAA equipment (e.g., Instrument
Landing System, Approach Lighting System, and Runway Status Lights).
Installation, relocation, operation, and maintenance of navigational aids required to support the
Proposed Action by FAA Airway Facilities Division.
