Dear Mr. Walker:
In accordance with your permit minor modification and renewal request received February 28,
2020, subsequent additional information received July 1, 2020, we are forwarding herewith Permit No.
WQ0002648 dated September 10, 2020, to Seagrove-Ulah Metropolitan Water District for the continued
operation of the subject wastewater treatment and irrigation facilities.
The following modifications to the subject permit are as follows:
➢ This facility will only be permitted for use of the 30,000 GPD domestic wastewater treatment
facilities. Consequently, the permitted flow has been reduced to 30,000 GPD and all
connections to the old industrial wastewater treatment facilities shall be removed or sealed.
➢ The 1,009,563 gallon synthetically lined wet weather storage lagoon (Lagoon 91) will not be
installed as previously permitted and all references and conditions related to this structure have
been removed.
➢ If the Permittee intends to increase the permitted flow capacity up to the previously approved
design flow (i.e. not more than 120,000 GPD) in the future, modifications to the treatment and
storage units must be made following a formal permit modification.
This permit shall be effective from the date of issuance through April 30, 2027, shall void Permit
No. WQ0002648 issued July 20, 2015, and shall be subject to the conditions and limitations therein. The
Permittee shall submit a renewal application no later than November 1, 2026.
Please pay attention to the monitoring requirements listed Attachments A, B, and C for they may
differ from the previous permit issuance. Failure to establish an adequate system for collecting and
maintaining the required operational information shall result in future compliance problems.
