Subject: Issuance of NPDES Permit NCO007552
Freemason VVTP

Dear Ms. Knighton:
The Division received your application for a wastewater discharge permit on July 18, 1997.
Division personnel have reviewed and approved your application. Accordingly, we are forwarding
herewith the attached NPDES discharge permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215 .1 and the Memorandum of Agreement
between North Carolina and the U.S. Environmental Protection Agency dated December 6, 1983,
and as subsequently amended.
The following changes have been made to the subject permit:
• The pH monitoring requirement has been removed.
• Monitoring requirements for Iron, Chloride and Total Residual Chlorine have been
added.
• Monitoring frequencies for all parameters have been added.
• '"'reekly- instream turbidity monitoring has been added.
Quarterly Total Phosphorus, Total Kjeldahl Nitrogen and Nitrate/Nitrite monitoring
requirements have been removed from the subject permit. Sampling for these parameters may
be halted immediately. The documented results from the monitoring data submitted to the
Division are well below the established levels of concern (3.0 mg/l for Total Nitrogen and 1.0 mg/1
for Total Phosphorus).
Please note that a separate discharge permit (NC0086291) is being issued for the Beaver
Hill Water Treatment Plant. The subject permit applies to the Freemason Water Treatment Plant
only.
If any parts, measurement frequencies or sampling requirements contained in this permit
are unacceptable to you, you have the right to an adjudicatory hearing upon written request

PART III - OTHER PERTINENT INFORMATION
I. Is this facility being constructed with Construction Grant Funds or are any public monies involved
(municipals only)? NA
2. Special monitoring or limitations (including toxicity) requests:
none
3. Important SOC, JOC, or Compliance Schedule dates (indicate):
Activity Date
Submission of Plans and Specifications
Begin Construction
Complete Construction
4. Alternatives Analysis Evaluation: Has the facility evaluated all of the non-discharge options available?
Provide Regional perspective for each option evaluated.
Spray Irrigation: not feasible
Connection to Regional Sewer System: Possible, but salts from water softener would most likely
disrupt biology of waste water treatment plant and shorten the life of the sprayfield. Therefore not
a recommended option.
Subsurface Disposal: not feasible
Other Disposal Options: none
5. Other Special Items: none
PART IV - EVALUATION AND RECOMMENDATIONS
The results of the inspection indicate that the plant was in compliance with the limitations and conditions of
the permit. In general, the plants are well maintained. The effluent from both plants appeared clear and free
of visible solids. The biota of Filbert Creek did not seem to be affected by the discharges. A cursory review
of data generation and tracking, sampling practices, and self-monitoring data revealed no discrepancies. It is
recommended that the permit be renewed for a period of five years.
