<p class="MsoNormal" style="margin-bottom:6.0pt"><span style="font-family:"Times New Roman",serif">The RIDEM Alternative OWTS Technology Certification issued to Eljen Corporation for Geotextile Sand Filter (GSF) and the associated manual for design, installation
and inspection have been revised (see attached). These two documents are also available via links within the list of approved technologies posted to the RIDEM website. This updated list was posted November 16, 2018. The List of Approved Technologies is available
on the RIDEM website at <a href="http://www.dem.ri.gov/programs/benviron/water/permits/isds/pdfs/ialist.pdf">

<p class="MsoNormal"><u><span style="font-family:"Times New Roman",serif">Overview of Changes</span></u><span style="font-family:"Times New Roman",serif">: The primary reason for the certification and design manual updates associated with Eljen GSF was to review
and approve Eljen Corporation’s decision to require venting when cover over the system exceeds 18”, rather than 24” as previously specified. The certification was also updated to reflect some of the newer elements RIDEM has been incorporating into more recent
certifications, including reference to the associated design manual revision date. To minimize confusion as to which version of the manual has been approved for use in RI the date of the approved manual has been incorporated into the technology certification
document. In addition, a pdf version of the approved manual has been made available on the DEM website (see link shown above).<o:p></o:p></span></p>
