How do I know if my site discharges to a priority watershed?

Priority construction sites include any site that discharges to:

  1. A waterbody which is listed on the most recently EPA-approved 303(d) list of impaired waters for turbidity, siltation, or sedimentation,
  2. Any waterbody for which a TMDL has been finalized or approved by EPA for turbidity, siltation, or sedimentation,
  3. Any waterbody assigned the Outstanding Alabama Water use classification in accordance with ADEM Admin. Code r. 335-6-10-.09, and
  4. Any waterbody assigned a special designation in accordance with ADEM Admin. Code r. 335-6-10-.10, the CBMPP must be submitted to ADEM for review along with the NOI.

 

To determine if your site is discharging into a priority area, there are CSW GIS files available for download below as well as a list of TMDL and 303(d) waters.
