The compliance record for this facility is very poor; an enforcement action was initiated by the
Region on August 22, 1994. No change in limits is recommended per conversation with
Region, but an ammonia limit may be required in the future.
A change in the instream, downstream monitoring location is recommended. Request Region
review of this recommendation on the following pages.

Parameter(s) are water quality limited. For some parameters, the available load capacity of
the immediate receiving water will be consumed. This may affect future water quality based
effluent limitations for additional dischargers within this portion of the watershed.

Request Region comment as to another possible downstream location which is on Mull Creek.
MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS
Adequacy of Existing Treatment
Has the facility demonstrated the ability to meet the proposed new limits with existing treatment
facilities? Yes No
If no, which parameters cannot be met?
Would a "phasing in" of the new limits be appropriate? Yes No
If yes, please provide a schedule (and basis for that schedule) with the regional
office recommendations:
If no, why not?
Special Instructions or Conditions
Wasteload sent to EPA? (Major) (Y or N)
(If yes, then attach updated evaluation of facility, including toxics spreadsheet, modeling
analysisif modeled at renewal, and description of how it fits into basinwide plan)
Additional Information attached? (Y or N) If yes, explain with attachments.

• Facility Name Claremont - North Waste Water Treatment Plant Permit # NC0032662 - 001
CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant
mortality is 13 % (defined as treatment two in the North Carolina procedure document). The permit
holder shall perform quarterly monitoring using this procedure to establish compliance with the permit
condition. The first test will be performed after thirty days from the effective date of this permit during
the months of Jan., Apr., Jul., and Oct. Effluent sampling for this testing shall be performed at
the NPDES permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter code
TGP3B. Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine
of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of
the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division
of Environmental Management indicate potential impacts to the receiving stream, this permit may be re-
opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival and appropriate environmental controls, shall constitute an invalid test and will require
immediate retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will
constitute noncompliance with monitoring requirements.

Note for Farrell Keough
From: Matt Mathews
Date: Mar 28, 1995 10:10 AM
Subject: RE: Claremont - North
To: Farrell Keough
The facility's tox record is relatively good over the last two years with the exception of last
Oct -Nov. Review of their DMR data indicates that ammonia may have caused the failures,
but that is only speculation. TIE procedures would be required to make an actual
determination. Copper has been somewhat elevated over the last year as well, but not
enough in my opinion to have caused the failures given the 13% effluent dilution at which the
tox tests are performed.
From: Farrell Keough on Tue, Mar 28,1995 7:41 AM
Subject: Claremont - North
To: Matt Mathews
NC0032662
please let me know if you have any comment on this facility and its toxicity record. I have a
comment about problems with ammonia in my notes, but no tracking for it.

copper, nickel, lead, and zinc, and nutrient monitoring.
1994: Specuattive Limits given for expansions from 0.100 to 0.140 and 0.200 mgd, [Lyle Creek basin strategy limits applied]
Letter from City Manager, (September 7, 1994) indicates that a completed pump station will divert approximately 20 - 30,000 gpd from
the North Plant to the McLin Creek Plant. Following this, the Western Steer / Mom 'n Pops now discharges to McUn and not the North
Plant.

Re: North WWTP

Dear Mr. Gleason:
U,
The City of Claremont completed work on School Branch Pump Station �,
and began diverting approximately 20,000 to 30,000 gallons per day
of wastewater from the North WWTP to McLin Creek WWTP on September
1, 1994.
Flow data recorded at the North WWTP over the past week indicates
that the average daily flow is in compliance with the NPDES permit
limit of 100,000 gallons per day.
With the completion of the pump station project, wastewater fro
Western Steer/Mon 'n Pops (WSMP) is not discharged to McJAIT eek
WWTP. We believe this, along with the reduction in hydraulic flow,
will significantly improve the performance of the North WWTP.
We hope that the above information will mitigate any enforcement
action for non-compliance of the North WWTP permit limits.
Please call me if you have questions or require additional information.
Yours very truly,
CITY OF CLAREMONT

Dear Joe:
RECEIVED
JAN 1 1 1;95
FACILITIES ASSESSMI"U T UNIT
Enclosed is a complete copy of the new Enforcement Response
Plan which was adopted by the Council on December 5, 1994.
Please call me if anything is missing.
Cordially,
M.D. McGinnis
City Manager
CITY OF CLAREMONT
PRETREATMENT PROGRAM
ENFORCEMENT RESPONSE PLAN
1. Introduction
RECEIVED
JAN 1 1 1995
FACILITIFS ! SSESSPWNT UNIT
It is the responsibility of City of Claremont to enforce all applicable
Federal, State, and local pretreatment regulations. These regulations are
outlined in Federal regulation 40 CFR 403 and State regulation 15A NCAC 2H
.0900, and the local SUO. This Enforcement Response Plan (ERP) has been
established as an element of the POTW's pretreatment program. The purpose
of the ERP is to provide for fair and equiable treatment of all Users for
anticipated enforcement situations. In general, enforcement actions will be
taken in accordance with this enforcement Response Plan. However, the
enforcement actions available are not exclusive as discussed in the SUO.
Therefore, any combination of the enforcement actions can be taken against
a non -compliant user.
2. Enforcement Actions Available to the City
The City Manager or his Designated Appointee is empowered through North
Carolina General Statute (NCGS) 143-215-6.A and the local Sewer Use Ordinance
(SUO) to take a wide variety of enforcement actions. The following is a list
of those actions and the corresponding section of the local SUO that describes
each.

5-2-81 (e)
5-2-81 (f)
5-2-82
5-2-83 (b)
5-2-83 (c)
In addition to the actions listed above, a User who violates the provisions
of NCGS 143-215.6B may be referred by the City Manager or his Designated
Appointee to the District Attorney for possible criminal prosecution.
In determining the amount of civil penalties for a particular violation
the City Manager or his Designated Appointee shall consider the following
factors.
1. The Degree and extent of the harm to the natural resources, to
the public health, or to public or priviate property resulting
from the violation;
2. The duration and gravity of the violation;
3. The effect on ground or surface water quantity or quality or on air
quality;
4. The cost of rectifying the damage;
5. The amount of money saved by non-compliance;
6. Whether the violation was committed willfully or intentionally;
7. The prior record of the violator in complying or failing to comply;
8. The costs of enforcement to the POTW.
Adjudicatory hearing procedures regarding permit decisions, civil penalties, and
administrative orders may be found in the SUO.
3. Investigation of noncompliance
The City Manager or his Designated Appointee will generally investigate User
compliance with permits or the provisions of the SUO in three ways:
1. on -site inspections of the User to include scheduled and
unscheduled visits;
2. scheduled and unscheduled sampling of the Users effluent;
3. review of self -monitoring data, if required, from the User.
The compliance status of Significant Industrial Users will be evaluated
at a minimum once every 6 months.
4. Types of violation
The following is a list of different types: of violations, by category.
This list is not inclusive, but serves as a general list of anticipated
types on noncompliance. The User's permit, local SUO, and State and
Federal regulations serve as additional references for pretreatment
requirements.
Unpermitted Discharges. Users are responsible for obtaining and
renewing permits, if required.
Permit Limits. Users are responsible for maintaining compliance with
all effluent limits. The POTW will evaluate the extent of the limits
violation(s). In determining the extent of violation(s), Significant
Non -Compliance (SNC) as defined by State and EPA regulations will
be determined.
Self -Monitoring Violations. A User who fails to adequately conduct all
the monitoring required in the permit, including monitoring frequencies
and sampling methods specified,is in violation. This includes a User
who does not resample per their permit when a limit violation occurs.
Reporting Violations. A User who fails to provide information (e.g..
self monitoring reports) required in their Permit or the SUO in the
required time frame is in violation. Late or incomplete reports will
also be considered violations. A SIU who submits a report more than
30 days late is considered in SNC.
Permit Conditions. Failure to apply or reapply for a permit is considered
a violation. Users who violate the general or other conditions (e.g.. slug
loading, dilution prohibition) outlined in their permits or the SUO shall
be considered to be in violation.
Enforcement Orders. Failure to meet the requirements of an order (e.g..
interim limits, milestone dates), whether the order was entered into
voluntarily or mandated by the POTW, shall be considered a violation.
Missing a scheduled compliance milestone by more than 90 days in considered
SNC.
5. Responses: Timeframes, Responsible Officials, Escalated Actions.
The attached chart further outlines types of violations and specifies
POTW actions (initial and escalated), timeframes, and the officials
responsible for completing the actions. This chart shall be considered
a part of the Enforcement Response Plan.
Responses to violations, affecting the operation of the POTW, resulting
in POTW NPDES violations, or resulting in environmental harm or endangerment
to human health will be taken immediately or as soon as possible following
discovery.
A User may be sent a Notice of Violation (NOV) or Notice of Noncompliance
(NNC) for each individual violation. Alternatively, the violations may be
summarized over a period of time not to exceed 6 months. In general, NOVs
in response to violations of permit limits will be taken within 30 days
of discovery of the violations. Users found to be in SNC for two (2)
consecutive 6 month periods will be issued an enforceable order to return
to compliance. In all cases, escalated or continuing enforcement action
will be taken against Users who do not return to compliance in a timely
manner.
Cases of falsifying reports, tampering with monitoring or sampling equipment,
or otherwise preventing the collection of representative data may be referred
to the District Attorney for possible criminal investigation.
Show cause hearings may be held at the City Manager or his Designated
Appointee discretion prior to taking enforcement actions.
