In accordance with your permit renewal request received March 22, 2005, we are forwarding
herewith Permit No. WQ0002838 dated February 8, 2006, to ARC4BFND, LLC (d.b.a. ARC
Communities 15, LLC) for the continued operation of the subject wastewater treatment and surface
irrigation facilities.
Throughout the last permitting cycle, the system has not been adequately maintained nor properly
operated. Several maintenance issues have been corrected within the last six (6) to twelve (12) months in
order to improve operation. The Division has concern with the currently permitted application rates.
Inspections over the last year have often observed ponding and two occasions of off -site runoff.
Conditions have been added to address several noted deficiencies and are in bold for immediate
attention. There are several conditions that have compliance schedules associated with them;
specifically, Conditions 1.7., I.8., I.9., I.10., U.14., and H1.2.
This permit shall be effective from the date of issuance until January 31, 2011, shall void Permit
No. WQ0002838 issued November 17, 2000, and shall be subject to the conditions and limitations as
specified therein. Please pay particular attention to the monitoring requirements in this permit. Failure to
establish an adequate system for collecting and maintaining the: required operational information will
result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within thirty (30) days following receipt of
this permit. This request must be in the form of a written petition, conforming to Chapter 150B of the
