NDZ
Polygon layer representing the geospatial extents for No Discharge Zones (NDZ) for boats and vessels in Virginia. This includes approved NDZs and NDZs in the application and approval process. Polygons derived using 1:24K NHD data and description from EPA final and submitted determinations for NDZ areas which includes lat/long geographic descriptions.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The code of Virginia (§ 62.1-44.33; see “References” section) requires the establishment of tidal creeks of the Commonwealth as No Discharge Zones, where documented and undocumented boats and vessels are prohibited from discharging treated or untreated waste into Virginia’s waters. The code further states that the establishment of an NDZ is to be premised on the improvement of impaired tidal creeks. However, because NDZs are federally designated, the U.S. Environmental Protection Agency (EPA) has the final decision as to whether a waterbody is designated as an NDZ.NDZ layers are the spatial representations of the surface waters that are designated No Discharge Zones in Virginia. </SPAN></P><P><SPAN /></P><P><SPAN>Data will be reviewed and updated as new NDZ areas are added or removed from layer by EPA determination or DEQ decision, approximately annual update. </SPAN></P></DIV></DIV></DIV>
