Sugar SR0082950 <br />Response Letter <br />Attachments: 17017 MTI - EHD Comments 2021-01-07.pdf <br />CAUTION: This email is originated from outside of the organization. Do not click links or open attachments unless you recognize the <br />sender and know the content is safe. <br />Jeff, <br />I have been able to update the documents to address your comments and try and reduce the confusion. Attached is the <br />response letter and below you will find a link to the aggregated submittal package. The way it is organized is as follows: <br />1. The front section is the sewer design memo that address staff count and the leach field design and operational <br />parameters. <br />2. The memo has 4 appendices. <br />Appendix A is the original Chesney nitrate loading study used as reference for field data <br />Appendix B is the updated nitrate loading study that address many of your comments <br />Appendix C is the original Chesney groundwater and soil testing just as a reference document <br />Appendix D is the revised improvements plans including the proposed expansion and site changes <br />In a nut shell I was able to respond thoroughly to your concerns and comments. In the end I was able prove out the <br />nitrate loading is not an issue, and was able to increase the daily use per employee by 387o over the memo you reviewed <br />and a little over 10% from the previously approved design that was installed in the first permit for 400 employees. This <br />should give us a safety factor. <br />Aggregated Submittal Link: <br />https://www.dropbox.com/sh/kf238m92o5ikfxk/AADTodvJvVJuFeISXEOQNkTxa?d1=0 <br />Regards, <br />Paul Schneider, PE, QSD/QSP <br />President � Managing Principal <br />3428 Brookside Road, Stockton, CA 95219 1 209.943.2021 <br />900 Howe Avenue, Suite 200, Sacramento, CA 95825 916.520.2777 <br />111 North Market Street, Ste 300, San Jose, CA 95113 � 408.754.2021 <br />100 Sycamore Avenue, Ste 100, Modesto, CA 95354 1 <br />209.762.3580 <br />m 1 209.607.0710 f 209.942.0214 <br />siegfriedeng.com <br />This electronic data is provided by Siegfried, as a courtesy.
