LEA Advisory 20 Attachment-Inspection Guidance for SW Landfills Page 45 of 52 MSWLF units which dispose of less than 20 tons of municipal solid waste daily and otherwise meet the small landfill exemption criteria in 40 CFR §258.1(f) are not subject to the following regulations until October 9, 1995. MSWLF units which have any evidence of ground-water contamination are not eligible for this exemption. 17258.10 Airport Safety (a) Owners or operators of new Municipal Solid Waste Landfill units (MSWLF), existing MSWLF units, and lateral expansions that are located within 10,000 feet(3,048 meters) of any airport runway and used by turbojet aircraft or within 5,000 feet(1,524 meters) of any airport runway end used by only piston-type aircraft must demonstrate that the units are designed and operated so that the MSWLF unit does not pose a bird hazard to aircraft. (b) Owners or operators proposing to site new MSWLF units and lateral expansions located within a five-mile radius of any airport runway end used by turbojet or piston-type aircraft must notify the affected airport and the Federal Aviation Administration (FAA). (c) The owner or operator must place the demonstration made pursuant to paragraph (a) of this section in the operating record and notify the board that it has been placed in the operating record. Definitions: (d) For purposes of this section: (1) "Airport"means public-use airport open to the public without prior permission and without restrictions within the physical capacities of available facilities. (2) "Bird hazard"means an increase in the likelihood of bird/aircraft collisions that may cause damage to the aircraft or injury to its occupants. The inspector should obtain a map of the area and, with a compass or ruler, measure the distance between the airport and the MSWLF unit. If it meets the distance criteria and the definition of "airport" (the inspector may check with the airport or FAA to determine if the airport is a public facility as defined in this standard), then the inspector should verify the following: 1. A demonstration has been done if the landfill is within 5000 feet of an airport used by piston- type aircraft or 10,000 feet of a runway used by turbojet aircraft. 2. A demonstration has been placed in the operating record and the Board notified. 3. Any MSWLF or lateral expansion of an existing unit that began operating after the effective date of these regulations has notified the affected airport and FAA. A determination of the adequacy of this demonstration is not necessary but may be appropriate if the inspector believes a potential bird hazard exists. The demonstration should address at least the following: 1. Is the airport facility within the regulated distance? 2. Is the runway part of a public-use airport? 3. Does/will the existence of the MSWLF increase the likelihood of bird/aircraft collisions that may cause damage to the aircraft or injury to its occupants? http://www.ciwmb.ca.gov/pe/advisoi-y/20/attach20/20atteli l.itm 8/11/98
