System boundary Sample Clauses

System boundary. The system boundary definition is a critical phase in LCA studies, as it determines the unit processes to be included in the product system. This phase is necessary for a comprehensive understanding of a product's environmental impact, as it may encompass all life cycle stages, from raw materials acquisition to disposal, or not [15]. The selection of system boundaries in LCAs can significantly impact the results and conclusions of the assessment [16]. The system boundary choice is influenced by data availability and the study’s goal. The system boundary alternatives include the "gate-to-gate" approach, which only incorporates manufacturing data, the "cradle-to-gate" approach, which encompasses raw materials extraction up to the supplier transport, the "cradle-to-use" approach, which further integrates the evaluation of the use phase, and finally, the "cradle- to-grave" approach, which comprehensively includes the entire lifecycle of a product. The cradle-to-grave approach has been found as the most used among the investigated studies (Figure 9). Figure 9: System boundary in LCA investigated studies

System boundary. A first step in the developing of the LCA has been the definition of the system boundaries. Figure 2 shows the system boundary of the system analysed. Three different phases have been considered in the analysis: the manufacturing phase – which includes the production of the batteries and all the single components up to the glider; the use phase – which includes the production of electricity needed to recharge the battery; the end of life phase – which includes from the reprocessing of the vehicle including the battery, up to the recovery of some metals. For all the phases, direct, indirect and avoided burdens have been accounted for. The functional unit used in this study was 1 km driven by one vehicle. To account for the manufacturing and the disposal phase, an assumption of the total km driven in the entire life cycle of the vehicle was made. Based on previous studies [6], [7], a total life cycle of 150,000 km was considered for both BEVs and ICEVs.

  • System Logging The system must maintain an automated audit trail which can 20 identify the user or system process which initiates a request for PHI COUNTY discloses to 21 CONTRACTOR or CONTRACTOR creates, receives, maintains, or transmits on behalf of COUNTY, 22 or which alters such PHI. The audit trail must be date and time stamped, must log both successful and 23 failed accesses, must be read only, and must be restricted to authorized users. If such PHI is stored in a 24 database, database logging functionality must be enabled. Audit trail data must be archived for at least 3 25 years after occurrence.

  • System Description The wet detention basin is designed to trap 80% of sediment in runoff and maintain pre-development downstream peak flows. The basin has two forebays (smaller ponds) located at the low end of two grass xxxxxx. In addition to runoff conveyance, the grass xxxxxx also allow infiltration and filtering of pollutants, especially from smaller storms. The forebays are each 4 feet deep. They are connected to the main pool by 18 and 24-inch metal pipes that outlet onto a rock chute. The forebays will trap coarse sediments in runoff, such as road sands, thus reducing maintenance of the main basin. The main pool will trap the finer suspended sediment. To do this, the pond size, water level and outlet structures must be maintained as specified in this Agreement (see Figures 1, 2 and 3). The main basin receives runoff from a 67.1 acre drainage area (41.2 acres within the subdivision and 25.9 acres off-site drainage coming from the east). During high rainfall or snow melt events, the water level will temporarily rise and slowly drain down to the elevation of the control structure. The water level is controlled by a 12-inch concrete pipe extending through the berm in the northwest corner of the basin (see Figures 1 and 3). On the face of the 12-inch pipe, there is metal plate with a 3-inch drilled hole (orifice) with stone in front of it. This orifice controls the water level and causes the pond to temporarily rise during runoff events. Washed stone (1- 2” diameter) is placed in front of the orifice to prevent clogging. High flows may enter the grated concrete riser or flow over the rock lined emergency spillway. “As-built” construction drawings of the basin, showing actual dimensions, elevations, outlet structures, etc. will be recorded as an addendum(s) to this agreement within 60 days after [Municipality Name] accepts verification of construction from the project engineer.
