Finished grade means the grade upon completion of the fill or excavation.
Established Grade means that grade established by the City for the particular area in which a sidewalk is to be constructed.
2 Wire Analog Voice Grade Loop or “Analog 2W” provides an effective 2-wire channel with 2-wire interfaces at each end that is suitable for the transport of analog Voice Grade (nominal 300 to 3000 Hz) signals and loop-start signaling. This Loop type is more fully described in Verizon Technical Reference (TR)-72565, as revised from time-to-time. If “Customer-Specified Signaling” is requested, the Loop will operate with one of the following signaling types that may be specified when the Loop is ordered: loop-start, ground-start, loop- reverse-battery, and no signaling. Customer specified signaling is more fully described in Verizon TR-72570, as revised from time-to- time. Verizon will not build new facilities.
Working level month (WLM) means an exposure to 1 working level for 170 hours (2,000 working hours per year divided by 12 months per year is approximately equal to 170 hours per month).
Minimum Level (ML) means the concentration at which the entire analytical system must give a recognizable signal and an acceptable calibration point. The ML is the concentration in a sample that is equivalent to the concentration of the lowest calibration standard analyzed by a specific analytical procedure, assuming that all the method-specified sample weights, volumes and processing steps have been followed.
