Filter Design Sample Clauses

Filter Design. Filters determine the relationship between the risk components (sources, habitats, and impacts to assessment endpoints). A filter consists of the weighting factors, 0 or 1, which indicate either a low or a high probability. We have incorporated two types of filters: an exposure filter and an effects filter. The exposure filter screens the source and habitat types for the combinations which are more likely to result in exposures (i.e., receptors in the habitat will come into contact with stressors generated by the source). The effects filter screens the source and habitat combinations for those that are more likely to affect a specific assessment endpoint. An example describes the design of both an exposure and an effects filter (see Example 1). The first step in designing an exposure filter is to determine which stressors are produced by the sources. Professional knowledge is then used to answer two sequential questions about each stressor in relation to specific source-habitat combinations • Will the source release or cause the stressor? • Will the stressor then occur and persist in the habitat? If the answer to both questions is yes, then a 1 is assigned to the source-habitat combination. If the answer to either question is no, then a 0 is assigned. The design of an effects filter is similar, but a separate filter is made for each assessment endpoint. The first step in this process is to determine what type of effects are important to the specific endpoint. For instance, if maintaining crab populations is an assessment endpoint, some of the important effects to consider are toxicity, predation, and food availability. The questions asked to develop the effects filters are • Will the source release stressors that are known to cause this particular effect to the endpoint? • Are receptors associated with the endpoint sensitive to the stressor in this habitat? If the answer to both questions is yes, then a 1 is assigned to the source-habitat combination. If the answer to either question is no, then a 0 is assigned.

Filter Design. This example designs an exposure filter for three sources (i.e., effluent discharges, road runoff, and seafood processing ▇▇▇▇▇) and three habitats (i.e., mudflats, rocky intertidal, and deep benthic). The stressors examined include hydrocarbons and solids. Hydrocarbons are more likely to result from effluents and runoff than from seafood, while solids are more likely to result from seafood wastes and runoff than effluents. Combinations where the stressor is likely to be related to the source are assigned a value of 1. effluents 1 runoff 1 seafood 0 Not all of these sources will release stressors into the same habitats. The baseline established in the former tables is expanded to include different habitat types. Hydrocarbons Solids mudflats benthic rocky runoff 1 1 1 seafood 0 0 0 mudflats benthic rocky seafood 1 1 1 The assigned values of 1 are then re-evaluated and changed to 0 if the habitat is not likely to be exposed by that source. For instance hydrocarbons from liquid effluents discharged year-round could conceivably occur in any habitat. However, hydrocarbons from runoff are more likely to affect shoreline habitats than deep benthic habitats. Likewise, seafood processing plants are allowed to release solids offshore, but not to mudflats or rocky intertidal areas. Hydrocarbons Solids mudflats benthic rocky seafood 0 0 0 mudflats benthic rocky The completed exposure filter is made by merging each individual filter. During merging, a 1 over-rides a 0 so that all stressors are represented in the final filter. Exposure Filter mudflats benthic rocky seafood 0 1 0 This example designs an effects filter associated with an impact to the commercial fishery: decreased survival of the hatchery pink salmon fry released by the Solomon Gulch Hatchery. Effects that could influence this endpoint include: (1) acute toxicity to fry causing death during their migration out of the Port, and (2) increased predation on the migrating fry. Sources that can directly or indirectly cause these effects are assigned a 1. For instance, effluents and runoff can carry contaminants into the Port and directly cause toxicity. Seafood accumulations can result in anoxia and production of hydrogen sulfide by benthic bacteria, which indirectly results in toxicity. Seafood can also attract more scavengers and predators to an area. effluents 1 seafood 1 effluents 0 runoff 0 seafood 1 The baseline is expanded to include three habitat types: shallow subtidal, deep subtidal, and rocky interti...

  • Unbundled Copper Loop – Designed (UCL-D) 2.4.2.1 The UCL-D will be provisioned as a dry copper twisted pair loop that is unencumbered by any intervening equipment (e.g., filters, load coils, range extenders, digital loop carrier, or repeaters). The UCL-D will be offered in two versions - Short and Long. 2.4.2.2 A short UCL-D (18,000 feet or less) is provisioned according to Resistance Design parameters, may have up to 6,000 feet of bridged tap and will have up to 1300 ohms of resistance. 2.4.2.3 The long UCL-D (beyond 18,000 feet) is provisioned as a dry copper twisted pair longer than 18,000 feet and may have up to 12,000 feet of bridged tap and up to 2800 ohms of resistance. 2.4.2.4 The UCL-D is a designed circuit, is provisioned with a test point, and comes standard with a DLR. OC is a chargeable option for a UCL-D; however, OC is always required on UCLs where a reuse of existing facilities has been requested by Granite. 2.4.2.5 These loops are not intended to support any particular services and may be utilized by Granite to provide a wide-range of telecommunications services so long as those services do not adversely affect BellSouth’s network. This facility will include a Network Interface Device (NID) at the customer’s location for the purpose of connecting the loop to the customer’s inside wire. 2.4.2.6 BellSouth will make available the following UCL-Ds:

  • Unbundled Copper Loop – Non-Designed (UCL-ND 2.4.3.1 The UCL–ND is provisioned as a dedicated 2-wire metallic transmission facility from BellSouth’s Main Distribution Frame (MDF) to a customer’s premises (including the NID). The UCL-ND will be a “dry copper” facility in that it will not have any intervening equipment such as load coils, repeaters, or digital access main lines (DAMLs), and may have up to 6,000 feet of bridged tap between the End User’s premises and the serving wire center. The UCL-ND typically will be 1300 Ohms resistance and in most cases will not exceed 18,000 feet in length, although the UCL-ND will not have a specific length limitation. For Loops less than 18,000 feet and with less than 1300 Ohms resistance, the Loop will provide a voice grade transmission channel suitable for Loop start signaling and the transport of analog voice grade signals. The UCL-ND will not be designed and will not be provisioned with either a DLR or a test point. 2.4.3.2 The UCL-ND facilities may be mechanically assigned using BellSouth’s assignment systems. Therefore, the Loop Makeup (LMU) process is not required to order and provision the UCL-ND. However, CBX One-Stop can request LMU for which additional charges would apply. 2.4.3.3 For an additional charge, BellSouth also will make available Loop Testing so that CBX One-Stop may request further testing on the UCL-ND. Rates for Loop Testing are as set forth in Exhibit A of this Attachment. 2.4.3.4 UCL-ND Loops are not intended to support any particular service and may be utilized by CBX One-Stop to provide a wide-range of telecommunications services as long as those services do not adversely affect BellSouth’s network. The UCL- ND will include a NID at the customer’s location for the purpose of connecting the Loop to the customer’s inside wire. 2.4.3.5 OC will be provided as a chargeable option and may be utilized when the UCL-ND provisioning is associated with the reuse of BellSouth facilities. OC-TS does not apply to this product. 2.4.3.6 CBX One-Stop may use BellSouth’s Unbundled Loop Modification (ULM) offering to remove excessive bridged taps and/or load coils from any copper Loop within the BellSouth network. Therefore, some Loops that would not qualify as UCL-ND could be transformed into Loops that do qualify, using the ULM process.
