<p class="MsoNormal">The list of approved Advanced and Experimental OWTS Technologies was updated on July 23, 2020. The revised list was posted yesterday.

<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">The certification for BioBarrier was renewed on July 23, 2020. The new approval explicitly limits all future design approvals to a maximum design flow of 1500GPD. This design flow
cap applies to all OWTS applications including variances and repairs. The revised certification, nitrogen monitoring protocol requirements, and updated BioBarrier manuals are now available online.<o:p></o:p></li></ol>
<p class="MsoListParagraph"><o:p> </o:p></p>
<ol style="margin-top:0in" start="2" type="1">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">The list of approved pretreatment technologies has also been updated to clearly list next to each approved technology: the treatment capabilities, Pretreatment Category (Category 1
– Timed Dosed or Category 2-Socially Dosed) as applicable, and what type of license is required to submit a design utilizing a given technology. These changes were made to eliminate confusion for the professional design community.
