Do not click links or open attachments unless you recognize the <br /> sender and know the content is safe. <br /> Ms. Rivera and Mr.Ernest, <br /> Attached please find a revised permit text to close the piping in place at the above mentioned location based on verbal <br /> discussion to Steven J.Jones and Ryan Hultner while onsite. <br /> The primary reasons for the closure in place are 1)the proximity to other in-use equipment which is a safety hazard.2) <br /> Location of the piping run within the containment area for the loading racks,compromise in this area could result in a <br /> safety concern. <br /> It was requested that WPI Construction answer the following questions: <br /> 1) Means and method to slurry the pipe in place <br /> a. How will you pour the slurry in the pipe? WPI will install a 4"Bell by Male fitting to the fiberglass <br /> fitting in the sump then an adapter to reduce the size to 2",then a camlock fitting to allow the cement <br /> pump to connect directly. WPI will pump slurry from the cut nearer the loading rack towards the <br /> UST. We will see the slurry come into the UST with a visual inspection. Once slurry is visible from <br /> inside the UST sump the line will be capped at the fuel line sump. Fill the remainder of the UST <br /> sump. And verify both the piping and UST are properly closed in place. <br /> b. The pipe is currently open ended on both sides.How will you determine that the slurry is coming out on <br /> both ends?Visual inspection will be completed,we will be able to see each side. <br /> 2) Soil boring plan <br /> a. The requirement is(1)soil boring per 20'of pipe.There is 84'of pipe from the rack to the UST. Draft <br /> Boring permit application is attached,it still requires a signature from the driller,Gregg and we expect <br /> this Thursday 9/30. 4 borings are proposed. <br /> If you have any questions please reach out and I will be happy to address.Thank you. <br /> Erica J.Rodriguez,PMP <br /> Senior Scientist I Wayne Perry,Inc. <br /> Consulting-Construction-Engineering-Maintenance <br /> 8281 Commonwealth Ave. I Buena Park CA,90621 <br /> 0:714.826.0352 1 F:714.523.7880 1 C:714.267.5147 <br /> erodriguez@wpinc.com I www.Minc.com <br />
