Dispersion Model). Table 4.1 describes the input parameters that were used in the Runspec and PDM for the MOVES component of the analysis. 13 EPA released a new version of MOVES on October 7, 2014 as ▇▇▇▇▇▇▇▇▇. Future revisions to the PA and TSD should make use of this updated version of MOVES or any subsequent version at the time of update.

Dispersion Model). The inputs for the dispersion modeling followed EPA’s 1992 Guidance for CO determinations using CAL3QHC (version 04244) and were consistent with the approach used by the Federal Highway Administration (FHWA) Carbon Monoxide (CO) Categorical Hot-Spot Finding (FHWA, February 2014) for intersections. As for emissions modeling, dispersion modeling was performed using conservative underlying assumptions and, in many cases, worst-case inputs and assumptions. These inputs and assumptions are outlined below:  As a conservative assumption, the wind speed was set to 1.0 m/s (the lower limit of CAL3QHC meaningful input).  Wind direction was modeled every ten degrees from 0 to 350 degrees.  A mixing height of 1000 m was used, consistent with standard modeling procedures. Sensitivity testing has shown that due to the close proximity of the receptors, mixing height has negligible influence on dispersion analysis.  For urban modeling, a surface roughness (z0) of 108 cm was used, corresponding to a single family residential setting. The single family residential setting is the least rough setting for an urban environment and is conservative. The recommended surface roughness in urban areas can vary from 108 to 370 cm. For rural areas, a surface roughness of 1.0 cm was used, which corresponds to a moderately short grass height (6-8 cm) as identified in prairie grass.16 Shorter grass heights are unlikely to be found in most rural locations.  The 1992 EPA CO Guidelines specifies a stability class of D (neutral) for urban areas and E (stable) for rural areas. These guidelines were applied in the model.  Receptor Placement o Freeways and Arterials:  Receptors were modeled per the CAL3QHC and 1992 EPA Guidance. For both freeways and arterials, receptors were placed on both sides of the roadway extending out to 295 feet from the roadway and were modeled to establish decreasing CO concentrations with distance.  For freeways, receptors were located beginning at 30 feet from the outside lane to account for off-road safety clearance.  For arterials, receptors were located beginning at 10 feet from roadway edge (where the general public has access and is within the limitations of the model to predict valid concentrations). o Intersections and Interchanges:  Receptors were modeled per the CAL3QHC and 1992 EPA Guidance and began at 10 feet from roadway edge.  A grid of receptors was used in each quadrant to ensure the worst case concentrations were identified. The grid spaci...

  • Unbundled Channelization (Multiplexing) 5.7.1 To the extent NewPhone is purchasing DS1 or DS3 or STS-1 Dedicated Transport pursuant to this Agreement, Unbundled Channelization (UC) provides the optional multiplexing capability that will allow a DS1 (1.544 Mbps) or DS3 (44.736 Mbps) or STS-1 (51.84 Mbps) Network Elements to be multiplexed or channelized at a BellSouth central office. Channelization can be accomplished through the use of a multiplexer or a digital cross-connect system at the discretion of BellSouth. Once UC has been installed, NewPhone may request channel activation on a channelized facility and BellSouth shall connect the requested facilities via COCIs. The COCI must be compatible with the lower capacity facility and ordered with the lower capacity facility. This service is available as defined in NECA 4. 5.7.2 BellSouth shall make available the following channelization systems and interfaces: 5.7.2.1 DS1 Channelization System: channelizes a DS1 signal into a maximum of twenty- four (24)
