<p class="MsoNormal">Hello All,<o:p></o:p></p>

<div>
<p class="MsoNormal">My question is specific to ground mounted solar panels.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Do your communities define impervious surfaces beyond just a general definition? For example does your zoning bylaw/ordinance or stormwater management bylaw/ordinance include specific types of surfaces or structures as "impervious"? <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I came across a description of solar panels as "disjointed impervious" and that description was stated as being defined by the NPDES program, however I can't locate any reference to that on the EPA website for the program. Any insight would
be helpful. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Apologies if this question has come up before, I'll be sure to dig through the archives as well.<o:p></o:p></p>
