Centennial Project - Section 33 Pumping Test Plan 9 <br />September 2009 Powertech (USA) Inc. <br />Monitoring of Operations <br />• During operation of the step-rate and primary aquifer pumping tests monitoring will take <br />place 24 hours each day and detailed checks to insure proper operation of infrastructure <br />will take place at specific time intervals. During the step-rate test detailed checks of <br />proper operation will be constant. During the first 8 hours following start-up of the <br />primary pump test, detailed checks will take place every hour. Following the first 8 <br />hours of operation detailed checks will be conducted every 4 hours until the primary <br />pump test is complete. Below is a list of checks to be performed during operation of the <br />step-rate and primary aquifer pumping tests. <br />• Check fencing to insure integrity. <br />• Check Baker Tank water levels. <br />• Check pump flow rate. <br />• Check piping, fittings, and Baker Tanks for water leaks. <br />• Check fuel level in the electrical generator. <br />• Check real-time water level in the pump well. <br />At about midway through the primary aquifer test, water level checks will begin to take <br />place at distant monitoring wells completed within the production zone. The purpose of <br />this exercise is to insure a proper aquifer response is taking place that will allow an <br />adequate analysis of the collected pump test data. In addition, an adequate response in <br />• the distant monitoring wells will also dictate the length of the pump test. <br />Monitoring and detailed checks will also take place during the re-injection of the <br />produced pump test water. During the first 8 hours of re-injection constant monitoring <br />and detailed checks will take place to insure proper operation. After that, detailed <br />checks will take place every 4 hours between the hours of 8:00 AM and 8:00 PM every <br />day that re-injection is taking place. Below is a list of checks to be performed during the <br />re-injection process. <br />• Check Baker Tank water levels. <br />• Check injection flow rate and pressure. <br />• Check piping, fittings, and Baker Tanks for water leaks. <br />• Check fuel level in electrical generator. <br />• Check site fencing, gates, etc. <br />If at any point during the aquifer test or re-injection of the pump test water any leaks are <br />detected that cannot be immediately controlled, the operation of the pump test or re- <br />injection will cease immediately. <br />Radiological Monitoring <br />Experience with numerous pump tests has indicated there is no significant potential for <br />exposure to radiation that might be related to the wells and related activity.
