However, Section 3.4.4, second <br />paragraph states: "After the bentonite chip seal is constructed, the bentonite will be <br />allowed to hydrate for at least one hour before additional well development." <br />For consistency and employing prudent practices of installing an effective bentonite seal, the <br />text in Section 3.4.2 should be modified to state: " After the seal has been hydrated, it will <br />be allowed to cure for at least one hour prior further well sampling or construction <br />activities." <br />2. In Section 3.4.6, on page 12, the third paragraph down, the workplan states: water <br />that is purged from each well will be temporarily contained and stored in 55 -gallon <br />drums, and then discharged to the ground surface <br />Since there is the potential for impacted groundwater to be encountered during the <br />sampling program, this text should be revised to state: " ...water that is purged from each <br />well will be temporarily contained and stored in 55 -gallon drums, and pending <br />laboratory results maybe discharged to the ground surface <br />I hope that these minor changes to the workplan are sufficient to address the regulatory <br />concerns and you are able to obtain the necessary well permits for this project. If I can be of <br />any further assistance to you, please let me know. Thanks. <br />Sarah Battelle, CHG <br />Note that we have moved. Effective 51912011.
