These two stock ponds as well as the <br /> other stock ponds currently' being monitored, only contain water intermittantly <br /> in response to rainfall generated flows in Scullion Gulch. <br /> The location of each monitoring station is shown on Table II.C-35 of Volume 1 <br /> of the application. All stations are monitored monthly for field parameters <br /> (pH, elec. conductivity and'� temperature) and quarterly for a full suite <br /> analysis of the parameters listed on Table II.C-8 of Volume of the <br /> application. Due to the intermittant nature of surface water flows at <br /> stations SW-1 -1 , SW-3-1 , SW`-23-1 , SW-24-1 and SW-31 -1 , however, the normal <br /> monitoring frequency has been modified. Flows at these five stations are <br /> monitored as soon as possible following significant rainfall events. If the <br /> sampler at a particular station contains water, a full suite analysis is run. <br /> If the sampler is not reached immediately but within 2 hours of the rainfall <br /> event, field parameters are taken. Monitoring data for all nine surface water <br /> monitoring stations is reported to the Division on a quarterly basis. <br /> Quarterly reports are compiled and the data interpreted on a yearly basis in <br /> the form of an annual hydrology report submitted to the Division on January <br /> 1st of each year. <br /> • <br />
