<br />Well No. 2 PFAS WTP <br />Stantec No. 173420153 <br />Magney Project Number 616 <br /> <br /> <br />5/29/25 <br /> <br />Re: Time Extension for Substantial Completion <br /> <br /> <br />Dear Brian Lintgen, <br /> <br /> <br />This letter is to request a time extension for substantial completion, moving this date from 5/30/25 to 7/3/25 due to <br />the delayed delivery of the AqueousVets Filters, Cartridge Filter, and Valve Tree and the subsequent media <br />installation delay. <br /> <br />Per the contract, the filters, cartridge filter and valve tree were anticipated to deliver on April 30, 2025 and the <br />media installation was anticipated the week of May 12, 2025. Unfortunately, and out of Magney’s control, the <br />filters and associated equipment didn’t get delivered until 5/28/25 and we are currently anticipating delivery of the <br />media on 6/17/25 - essentially 30 day delays on both activities. <br /> <br />Per the attached start up plan, we have received and installed the filters and are currently installing the DIP to tie <br />the filters into the existing well piping. We are anticipating being complete with the piping and the Bac-T tests <br />complete the week of June 9th. This will put us on track to have AqueousVets install the media the week of June <br />16th and take Bac-T and the 5 day Nitrocimine Tests that week. If these tests pass during these first attempts, we <br />should be able to turn the filters over to the City of Lake Elmo on June 24th. If these tests don’t pass, we’re going <br />to have to retake the respective tests and will need additional days which is why we’re requesting until 7/3/25. <br /> <br />Please confirm that this time extension is acceptable to Stantec and the City of Lake Elmo and we can move the <br />Substantial Completion back to 7/3/25. <br /> <br />Thanks. <br /> <br /> <br /> <br /> <br />Peter Nordang <br />Project Manager <br />Magney Construction <br />612.272.3307
