Dear Mayor Adams:

iDENA—FF,YtIILLE REGIONAL OFFICE
. This is to inform you that the Environmental Sciences Section has not received your toxicity self -
monitoring report form for the month of July 2005. This is in violation of Title 15A of the North Carolina
Administrative Code, Chapter 2, Subchapter 2B, Section .0506 (a)(1)(A) which states that "monthly monitoring
reports shall be filed no later than 30 days after the end of the reporting period for which the report was made."
Your Discharge Monitoring Report for July 2005 has not been received by Central Files. Please remember
that reporting of toxicity self -monitoring data is a dual requirement. Toxicity test results must be entered on your
Discharge Monitoring Report and the Aquatic Toxicity Reporting Form (AT Report Form) must be submitted to:
DWQ/ESS, 1621 Mail Service Center, Raleigh NC. 27699-1621 within the required time frame.
You will be considered noncompliant with the reporting requirements contained in your NPDES Permit for
the month of July 2005 until you make acceptable demonstration to the Environmental Sciences Section that the
report form was submitted to this office within the required 30 day reporting period. Toxicity reporting and/or
monitoring violations subjects the facility to the enforcement authority of the Division.
Our records indicate a Notice of Violation was sent certified mail to the Town of Parkton dated 3/31/05 for
failing to report the January 2005 toxicity self -monitoring data within the required time frame. The Notice
explained toxicity test reporting procedures during quarters when toxicity testing is required by your discharge
permit.
The reverse side of this Notice also contains a summary of important toxicity monitoring and reporting
requirements. Please read this one page summary and if you have any questions concerning this Notice, please
contact Mr. Kevin Bowden with the Aquatic Toxicology Unit at [phone].
Sincerely,

WHOLE EFFLUENT TOXICITY MONITORING AND REPORTING INFORMATION
> The following items are provided in an effort to assist you with identifying critical and sometimes overlooked toxicity testing and
reporting information. Please take time to review this information. The items below do not address or include all the toxicity
testing and reporting requirements contained in your NPDES permit. If you should have any questions about your toxicity -
testing requirement, please contact Mr. Kevin Bowden with the Aquatic Toxicology Unit at [phone] or another Unit
representative at the same number. ..
> The permittee is responsible for ensuring that toxicity testing is conducted according to the permit requirement and that toxicity report
forms are appropriately filed.
> The reporting of whole effluent toxicity testing data is a dual requirement. All toxicity test results must be entered (with the
appropriate parameter code) on your monthly Discharge Monitoring Report which is submitted to:
North Carolina Division of Water Quality

Raleigh, NC 27699-1617
--IN ADDI-TION---
Toxicity test data (original "AT" form) must be submitted to the following address:
North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
> Toxicity test results shall be filed with the Environmental Sciences Section no later than 30 days after the end of the reporting
period (eg, January test result is due by the end of February).
> Toxicity test condition language contained in your NPDES permit may require use of multiple concentration toxicity testing upon
failure of any single quarterly toxicity test. If the initial pass/fail test fails or if the chronic value is lower than the permit limit, then at
least two multiple concentration toxicity tests (one per month) will be conducted over the following two months. As many analyses as
can be completed will be accepted. If your NPDES permit does not require use of multiple concentration toxicity testing upon failure
of any single quarterly test, you may choose to conduct either single concentration toxicity testing or multiple concentration toxicity
testing per the Division's WET enforcement initiatives effective July 1, 1999. Follow-up multiple concentration toxicity testing will
influence the Division's enforcement response.
➢ Toxicity testing months are specified by the NPDES Permit, except for NPDES Permits which contain episodic toxicity monitoring
requirements (eg, if the testing months specified in your NPDES permit are March, June, September, and December, then toxicity
testing must be conducted during these months).
> Should the permittee fail to monitor during a month in which toxicity monitoring is required, then monthly monitoring will begin
immediately until such time that a single test is passed. Upon passing this monthly test requirement, the permittee will revert to the
quarterly months -specified -in -the -permit -Please-note-that yourpermit may or may -not -contain thisianguage. -
➢ If your NPDES Permit specifies episodic monitoring and your facility does not have a discharge from January 1-June 30, then you
must provide written notification to the Environmental Sciences Section by June 30 that a discharge did not occur during the first six
months of the calendar year.
➢ If you receive notification from your contract laboratory that a test was invalidated, you should immediately notify the Environmental
Sciences Section at [phone] and provide written documentation indicating why the test was invalidated and the date when
follow-up testing will occur.
➢ If your facility is required to conduct toxicity testing during a month in which no discharge occurs, you should complete the
information block located at the top of the AT form indicating the facility name, permit number, pipe number, county and the
month/year of the subject report. You should also write "No Flow" on the AT form, sign the form and submit following normal
procedures.
> The Aquatic Toxicity Test forms shall be signed by the facility's Operator in Responsible Charge (ORC) except for facilities which
have not received a facility classification. In these cases, a duly authorized facility representative must sign the AT form. The AT
form must also be signed by the performing lab supervisor.
> To determine if your AT test forms were received on time by the Division of Water Quality, you may consider submitting your
toxicity test results certified mail, retum receipt requested to the Environmental Sciences Section.
