1 TY III - OTHER PROJECT ACTIVITIES Project partcpats shall appl the Geeral Gudeles to SSC CDM ethodologes attachet A to Appedx B provded at < utats utads. III.AX. Methae oxdato laer (MOL) for sold waste dsposal stes Techolog/easure 1. Ths ethodolog s applcable to project actvtes volvg the costructo of a ethae oxdato laer (MOL) 1 o top of a ucpal sold waste dsposal ste (SWDS) wth low resdual surface ethae esso (less tha L CH. -2.h -1 ). The purpose s to avod the release of ethae through bologcal oxdato the MOL. 2. The project actvt does ot recover or cobust ethae (ulke AMS-III.G) ad does ot udertake cotrolled cobusto of the waste (ulke AMS-III.E) or avod ethae producto through copostg (ulke AMS-III.). 3. Ths ethodolog s applcable as a ladfll aageet cocept where ladfll gas collecto ad treatet s ot applcable due to ether low cocetrato of ladfll gas (less tha L CH. -2.h -1 ) or due to other reasos whch ake the stallato of a gas collectg sste practcal. I order to verf whether ths applcablt codto s et project propoets shall ake the ex ate basele estato as per the procedures of paragraph 9 below dvded b the surface area of the SWDS.. Ths project actvt s ol elgble for SWDS (or dvdual cells of a SWDS) that are o loger recevg wastes for dsposal. Ths ethodolog s ot applcable case a legal regulato s place requrg the surface coverg wth ethae oxdzg aterals. The ethodolog s also ot applcable at SWDS (or dvdual cells of a SWDS) wth a actve gas extracto sste. 5. Measures are lted to those that result aual esso reducto of 60 ktco 2 equvalet or less. Boudar 6. The project boudar s the phscal geographcal ste: (a) (b) (c) Where the applcato of MOL takes place (sold waste dsposal ste); Where the producto of MOM (refeet of SB ateral) takes place; ad Where the trasportato of MOM to the SWDS occurs. 1 The MOL cossts of Methae Oxdsg Materal (MOM) whch s bologcall ad echacall processed boass kow as refed stablzed boass (SB). SB s copost or copost-lke product avalable fro echacal bologcal treatet (MBT) plats or aerobc copostg facltes. or the producto of ethae oxdsg ateral (MOM) SB s used as raw ateral ad subtted to refeet ad aturato order to fulfl the techcal requreets for MOL applcato. A gas dstrbuto laer s placed below the MOM. 1/13
