Secondary Limits were still recommended, but metals monitoring as well as a Phenols limit and nutrient monitoring was
required.
Pretreatment
checking into this, it was discovered that an SIU did exist; YES Hosiery, (involved in dying). Pretreatment will be including language in
the Permit to gather information on this facility, (refer attached Email). Conversations w/ Pretreatment indicates that no residual toxics

MEMORANDUM
To: Jackie Nowell
Through: Larry Ausley
From: Matt Matthews r" o"
Subject: Whole Effluent Toxicity Limit
Catawba WWTP
NPDES No. NC0025542
Catawba County
The subject facility's current permit, effective March 1, 1993, includes a quarterly pass/fail toxicity
limit at 2.1 %. The facility has a permitted flow of 0.225 MGD. This limit was included in the permit
due to the waste contribution of two significant industrial users (SIUs). According to John Lesley of the
Mooresville Regional Office, both of the industries have since ceased discharge to the WWTP. The
facility has passed each of the seven whole effluent toxicity analyses completed since May of 1993. It
is the recommendation of this office and the Mooresville Regional Office that the whole effluent
toxicity limit be dropped upon renewal of the facility's permit.
If you require further information or comment, please contact me at 733-2136.

Hold on a minute, I did not know Catawba had any industrial users. Unless we have
crossed over to the twilight zone, Catawba does not have a pretreatment program. Therefore,
my opinion and LTMP data will be withheld at this time.

Town of Catawba NC0025542 NPDES permit will need special language for pretreatment,
Industrial Waste Survey Requirement. When you actually start drafting the permit, please
see me for the "current" Industrial Waste Survey language.
They have a user YES Hosiery, a hosiery dye shop. The user flow may be as high (liberal
estimate) as 12,600 gallons per day. Town's flow of 61,000 gallons per day.

c. Describe receiving stream features and pertinent
downstream uses: The receiving stream is a large creek
that is partially flooded due to Lake Norman. Lake
Norman is used as a water supply and•, for primary
recreation.
--PART II — DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1.
a. Volume of wastewater to be permitted: 0.225 MGD
(ultimate design capacity)
b. Current permitted capacity of the wastewater treatment
facility: 0.225 MGD
c. Actual treatment capacity of the current facility
(current design capacity): 0.225 MGD
d . Date(s) and construction activities allowed by previous
Authorizations to Construct issued in the previous two
years: N/A
e. Please provide a description of existing or substantially
constructed wastewater treatment facilities: The WWT
facility consists of dual bar screens, two aeration
basins, two clarifiers, chlorine disinfection,
instrumented flow measurement, and an aerated sludge
holding tank.
f. Please provide a description of proposed wastewater
treatment facilities: N/A
g Possible toxic impacts to surface waters: The facility
has
consistently passed chronic toxicity tests.
h . Pretreatment Program (POTWs only): The Town does not
have an approved pretreatment program. The Town does
receive some industrial wastewater. The Town should be
required to conduct an Industrial Waste Survey.
2. Residuals handling and utilization/disposal scheme:

Main Treatment Unit Code: 05003
PART III - OTHER PERTINENT INFORMATION
1. Is this facility being constructed with Construction Grant
Funds or are any public monies involved? N/A
2. Special monitoring or limitations (including toxicity)
requests: The Town has requested that toxicity monitoring be
removed from the NPDES Permit. It is recommended that
toxicity monitoring be dropped since the IWC is very low and
the facility has consistently passed toxicity tests.

6. Other Special Items: N/A
PART IV - EVALUATION AND RECOMMENDATIONS
The permittee, the Town of Catawba, has applied for permit
.renewal. The WWTP has adequate capacity since an industry has
•recently left the Town. There is one other industry in the Town
