Remedial actions, if not already implemented, should be taken to correct any noted problems. The Division of
Water Resources may pursue enforcement actions for this and any additional violations. If the violations are of a
continuing nature, not related to operation and/or maintenance problems, and you anticipate remedial
construction activities, then you may wish to consider applying for a Special Order by Consent (SOC).
We understand the above violations were related to failure of your secondary clarifier. Please note this is not
the first time this has occurred and why we encourage duality in treatment units while requiring them on new or
expanded facilities The Town needs to strongly consider adin_g its faci/ity or becominga partner in a
regional system to al/ow abandonment of the treatment faci//iy
If you have any questions concerning this matter or to apply for an SOC, please contact Dean Hunkele of the
Wilmington Regional Office at 910-796-7215.
Sincerely,
