From the adjusted data set, the top 10 percent of adjusted daily volumes in the period <br /> were then identified and averaged, as follows: <br /> Day of Week Date in 2017 Gallons Comment <br /> Thursday 6115 2432 Measured volume <br /> Monday 6/19 1799 Assumed volume <br /> Tuesday 6/20 2101 Measured volume <br /> Tuesday 6/27 2107 Assumed volume <br /> Friday 7/21 2921 Measured volume <br /> Monday 7/31 2154 Measured volume <br /> Tuesday 8/1 1771 Measured volume <br /> Average = 2184 <br /> The highest value in this period, occurring on July 21, slightly exceeds the current daily <br /> design flow for the LPP system. However this value must be read in context with the <br /> previous day's value, which was unusually low (1084 gallons) for a typical weekday. It is <br /> likely that the July 20 volume is under-represented and the July 21 volume is over- <br /> represented based on either the time of meter reading or pump cycling considerations, as <br /> described above. It is therefore reasonable to discount this high value as an anomaly, <br /> especially since there is no other similar occurrence in the study period. <br /> The average of the seven data points is 184 ns per day, which is approxima7Y <br /> percent of the daily design flow. Using an alternate statistical approach of eliminating the t./A � <br /> highest and loaves f these values, the resulting average i 119 ons, on tq/ <br /> approximatescent of the daily design flow.

Adding this volume to 2184 gpd yiel s 424 , or ab t 85 ent of the <br /> rated capacity of the existing LPP system. Under these conditio a system will still <br /> potentially have reserve capacity for other future additions; h ever, any tore addition <br /> will r uire separate evaluation and iustification. <br /> flnclusion If'y h <br /> o d"A%a d my s `� <br /> Based on the foregoing analysis, the existing LPP system on the Chestnut Ridge Camp &0w <br /> and Retreat Center property has adequate capacity to accept the additional wastewater <br /> flow from a proposed two-bedroom cottage, while continuing to accommodate the rate of <br /> wastewater loading experienced during the Summer 2017 camping season. <br /> End <br /> 5 <br /> 292 <br />
