Raven Park Dam (Stock Pond) SW-33-1 Grab <br />Sample <br />During the next permit term when underground mining operations within th D <br />coal seam progress into Federal Coal Lease No. C-8424, the permittee will <br />begin monitoring two additional stock water ponds, Lincoln Reservoir and <br />Halandras Reservoir beginning one year prior to mining within the lease area. <br />At present, only the portion of Scullion Gulch above Lincoln Reservoir is <br />monitored, not the stock pond itself. 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 />(pN, e]ec. conductivity and temperature) and quarterly fora 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 />
