John Funderburg, Principal Planner October 30.2018 Page 10 It is also important to note that Airport Director Russell Stark informed Mike La ' Forge that the Airport intends to extend the displaced threshold towards the end al-the acrport's runway, bringing Airfield gperations ether to the landfill. According to Mr. Stark, the Airport also intends to expand the concrete pad(utilized for air freight (cont.) operations) to the east, bringing it closer to the: landfill. The revised EJR trust evaluate whether this displaced t1ireshold extension and extended air freight operations pad would encroach into the 10.000-foot sepatition distance. D. The SDEIR Pails to Evaluate the Project's Potential to Result in an Increase in Odor Emissions. ' Forward landfill is already a source of offensive odors for the numerous receptors surrounding the facility. Given this fact,one would expect the SDEIR to thoroughly examine the potential for increased odors resulting from the new waste disposal sites. Unfortunately, this is not the crtsc. In fact, what is notable xbaut the odor impact analysis is what is mismillp 11. First,the SIDEIR does not identify the sources of adors at the landfill. The closest the document conies is a vague reference to odors emanating,through cracks in the surface cover or from tlx actual wastes themselves. SDFIR at I V.D-23. Sines the ' Forward SDEIR provides no detail regarding existing sources of ndors, we reviewed the "Landfill Gas Primer: An Overview for F.nvironrnental Health Professionals,Landfill (;as Safety and Healtli Issues," Depimment of Health and Hunan Services,November 10 2001, attached as Exhibit E. This document explains that, typically,odors from landfills ' are generated from the following sources: (1) green waste and food waste(Potential odors from aerobic and anaerobic decomposition of green waste and food waste during ' processing and transfer); (2)the working face of the landfill (potential odors from decomposing waste prior to application of cover); (3) land-fill gas(potential odaus from trace fugitive emissioms from the landfill surface, including hydrogen sulfide: (1125)and volatile organic compounds), and (4) landfill gas c-mndensate(potential odors from fugitive emissions frown the landfill gas condensate and processing system, including H2S and VOCs). tic revised EIR should conduct an evaluation of existing sources of odors from Forward landfill, ' Second, the SDEIR also dnes not provide any infortnation on current odor suppressant systems that may Na,in place at the facility. It is unclear whether Forward ' ijtlemptc to suppress odors at all or whether (lie SDEIR is simply not describing these aticnipLs. In any event, the revised FIR must include a substantive discussion of the landfill's odor suppressant system and its operational odor best management practices. SIIUTI: NJI1AAl_Y 1WLINhLRGER�ir
