Scope 1.1 The scope of this Guide is wide ranging to ensure market confidence for a successfully established wood chip fuel supply chain. A safe and reliable high performing wood chip energy system requires knowledge of characteristics, supply, storage, and procurement of the fuel. Wood chips in the context of this Guide are restricted to wood chips according to CAN/CSA-ISO 17225 Part 4. This Guide aims to bridge the gap between the suppliers and end users of wood chip fuel by a) providing information on the supply and feedstock characteristics of wood chips; b) providing technical guidance on bulk storage practices and safety considerations; c) describing key fuel properties of wood chips in CAN/CSA-ISO 17725 Part 4; and d) bringing common terminology and language to the marketplace. 1.2 The intended audiences for this guide include those involved in a) producing and supplying wood chips, including aggregators, sawmills, loggers, urban tree services, woodland management services, value added wood processors such as furniture and cabinet makers, and flooring manufacturers; b) project developers, including equipment manufacturers, engineering professionals, planning and procurement officers; and c) facilities managers, maintenance staff, and those responsible for the operation of biomass systems. 1.3 1.3.1 This Guide applies to small-scale to medium-scale facilities used in commercial and institutional buildings and larger-scale facilities, such as light industrial sites and district heating (see Table 1). The scale used for grouping the applications is for illustration only; in practice, some overlaps between the applications and the scales are expected. 1.3.2 Residential applications (
