Per your request, this Office has reviewed the documents
submitted for the subject WWTP project and offers the
following comments:
1. The Belmont WWTP;was under an SOC which expired on
December 1, 1991.! Completion, of the construction
activities requited by the SOC was achieved on
August 24, 1991.,The WWT facility, however,
continues to experience periods of noncompliance.
2. With regards to the proposed method and sequence
for construction,. this Office has no objections
provided the effects on day-to-day treatment plant
operation are minimized by the proposed repairs/
rehabilitation work. The City's engineer has
requested that a temporary NPDES Permit TSS limit
of 60 mg/1 be established during the rehabilitation
period. Due the short time frame involved (approx.
2 months), modifying the Permit for this purpose is
not practical. It is suggested that the Division
notify the City that if noncompliance occurs as a
result of repairs to the existing WWT facility,
enforcement may beheld in abeyance provided
compliance is achieved upon completion of the
repairs. An evaluation should also be made by
Technical Support to determine whether 60 mg/1
would cause WQ impacts in the receiving stream.
If you have any questions regarding this matter, please
advise.
