SummaryoftheDraftBillandConsultationPaper
TheACTGreenshavereleaseddraftlegislationcalledtheEnvironmentandConstructionOccupationsLegislation(WoodHeaters)AmendmentBillforcommunityconsultation.ThechangesproposedinthedraftlegislationareintendedtoreducetheproblemsassociatedwithpollutionfromwoodheatersintheACT.KEYPOINTS
ThedraftBilldoesNOTbanwoodheatersorrequireanyonetoreplaceexistingwoodheaters.
ThedraftBillwouldestablishnew,stricteremissionsandefficiency
standardsthatwoodheatersmustmeetbeforetheycanbesoldintheACTorinstalledinanACTresidence.
Overtimethiswouldmakeanimportantcontributiontoreducingthe
particulatepollutioncreatedbywoodheatersintheACT,aswellastheamountofwoodneededforfuel.
ThestandardswouldbringtheACTinlinewithjurisdictionsthatareleadingthewayinreducingwoodsmokepollutiontohelpaddresshealthandenvironmentalproblems.
o Theproposed1g/kgemissionsstandardwouldreduceparticulateemissionsperkgofwoodburnedfromtheaveragenewwoodheaterbyapproximately34%;
o The65%efficiencystandardwouldreducetotalwooduseover15yearsbyabout10%;
o Thecombined1g/kgemissionsstandardand65%efficiencystandardwouldreduceparticulatematterpollutionover15yearsbyupto65%.
Themeasuresarenecessarybecauseof:
Thenegativehealthimpactscausedbywoodsmokepollution.
o 70%ofparticulatematterpollutioninCanberracomesfromwoodheaters–whichislinkedtolungdisease,heartdiseaseandotherserioushealthproblems.

o Particulatematterlevelsinwinterare3timeshigherthanthe

RegulationofwoodheatersintheACT(andnationally)remains
inadequate.
o Thenationalemissionsstandardforwoodheatersallows4timesasmuchpollutionastheleadingjurisdictions,andthereisnonationalefficiencystandardatall.
Thisconsultationpaperrecommendsadditionalmeasuresforaddressingwoodsmokepollution,including:
o Introducingmobileairqualitymonitoringtoinformandimproveresponsestothepollutionproblem;
o Improvinglocalenforcementoptionstoensurepeopleusewoodheaterscorrectly;
o ImprovingthewayairqualitydataandthehealtheffectsofwoodsmokearecommunicatedtoCanberrans;
o Expandingthewoodheaterreplacementprogramtoincludelowemissionselectricheating,andanincreasedsubsidy.
Thisconsultationpapersuggestsseveraladditionalmeasuresforcommunitydiscussion,including:
o Ensuringallnewwoodheatersaresoldwithinformationaboutthehealthimpactsofwoodsmoke;
o Phasingoutnon‐compliantwoodheatersbysettingadatebywhichallwoodheatersintheACTmustmeetastandard;
o Phasingoutnon‐compliantwoodheatersbyrequiringtheirremovaluponthesaleofthepremises;
o Allowingtheinstallationofnewwoodheatersonlywhentheyarereplacingexistingwoodheaters,untilsuchtimeasanewhealth‐basedstandardhasbeendevelopedforreal‐lifeemissions;
o Usingmarketmechanismstoreducewoodheateremissions,suchasasalestaxorlicensingofwoodheaters.

* Waverly and Holyrod councils (Sydney): banned wood heaters * Various NSW local councils: using development control plans to control or prevent wood heater installations in particular areas (eg Camden Council, the Hills Shire Council, Manooka Valley, the Oran Park and Turner Road Growth Precincts). * Armidale Dumaresq Council (NSW): new wood heaters must meet an emissions standard of 3g/kg; 2.5g/kg for certain areas. * New Zealand: From 2005, all wood heaters installed in the urban environment must meet an emissions standard of 1.5g/kg and an efficiency standard of 65%. * Canterbury (Christchurch, NZ): New wood heaters must meet an emissions standard of 1g/kg and an efficiency standard of 65%. In most areas, new wood heaters cannot be installed except as replacements for more polluting wood heater models. From 2010, the use of solid fuel burners that are 15 years or older is banned between 1 April to 30 September each year. * Otago (NZ): by 1 January 2012, all wood heaters had to meet an emissions standard of 0.7 g/kg and an efficiency standard of 65% for new and existing heaters (or 1.5g/kg for heaters installed before 2007). This means old non-compliant heaters had to be removed. * Lincoln County and Sacramento (USA): ban on wood heaters. * Southern California – wood heaters not allowed in new houses. * Mammoth, Washoe County and Oregon (USA): phasing out wood heaters by removing them when the house is sold. * Montreal, Canada: Banned the installation of wood heaters (new or as replacements) from 2009.
