NORTH CAROLINA DEPARTMENT OF ENVIRONMENT, HEALTH, AND NATURAL RESOURCES DIVISION OF ENVIRONMENTAL MANAGEMENT Winston-Salem Regional Office June 6, 1990 MEMORANDUM TO: Mr. Dale Overcash i/ Supervisor NPDES Permits, WQ THROUGH: Mr. M. Steven Mauney, Supervisor Water Quality, WSRO n I- / FROM: Mr. Arthur R. Hagstrom 1°f 9° Environmental Engineer, WQ, WSRO SUBJECT: Woodlake MHP's NPDES Permit No. NC0023299 limit changes for their new Permit that will become effective May 1, 1994, Guilford County It appears that Technical Services must address the questions about the limits spelled out in the new permit that may provide treatment and real economic problems for the subject Permittee. The limits may force other options on the park owner. The WWTP serves both Woodlake MHP and a new subdivision now under development by Oakwood Land Development called Greybridge Subdivision. The WWTP ownership has been retained by Oakwood Land Development and the Woodlake MHP has been sold to another owner. Treatment service for the MHP is provided as part of the purchase price. It is probable that the investments in these two (2) developments will be adversely affected by the new limits. ARH / vrn Copy too : Central Files WSRO DIVISION OF ENVIRONMENTAL MANAGEMENT MEMORANDUM TO: Dale Overcash THRU: Ruth Swanek BLS Trevor Clements FROM: Mike Scoville ADS May 23, 1990 SUBJECT: Draft Permit Comments of Oakwood Land Development Corporation (NPDES No. NC0023299, Guilford County) I have reviewed the comments of the Oakwood Land Development Corporation regarding the draft NPDES permit for Woodlake Mobile Home Park, and offer the following response: 1. The letter mentions that beginning May 1, 1994, the permit contains just a daily maximum limit for NH3-N and no monthly average limit. I assume this is true because NH3-N is limited as a toxicant, and that no monthly average limit is applicable. If the Company wants, a monthly average NH3-N limit of 1.0 mg/1 could be added to the permit, but the daily maximum limit would still need to be met. 2. The permittee states that since their instream monitoring data show little or no reduction of DO as a result of the plants discharge, they are adequately protecting the environment and do not need more restrictive effluent limits. Due to limited access, however, their downstream monitor- ing site is only 300 feet downstream from their discharge, and is not in the optimal position to capture the true impact of the discharge. Also, the facility is currently operating at approximately half of their permitted wasteflow. While the instream data show that there is currently a minimal impact of the discharge immediately downstream, it does not necessarily mean that the stream is adequately protected at design conditions and7Q10 flow. 3. The zero -flow values for the 7Q10 and 30Q2 were not arbitrarily assigned, but estimated by USGS according to procedure. Technical Support would be glad to re -assess the wasteload allocation upon receipt of informa- tion that suggests a positive 7Q10. We would encourage the Company to com- plete a flow study as they have mentioned, but they should be in contact with USGS and Technical Support to assure that the study is valid and per- formed according to standard procedure. The letter indicated that the pond upstream of the discharge could possibly be used for flow augmentation dur- ing low flow periods. This may be a possible solution if the facility would agree to a minimum release requirement. It should be noted, however, that the pond water would probably not be of high quality during low flow periods due to high temperatures and little inflow. 4. Current Division policy for discharges to streams with 7Q10=0 and 30Q2=0 requires 1) that an engineering report evaluating alternatives to a surface water discharge be submitted within 12 months of permit issuance, and 2) effluent limits reflecting tertiary treatment and protecting against ammonia toxicity become effective three years after permit issuance. These requirements should not be changed. If the engineering report sufficiently shows that there are no feasible discharge alternatives, the limits should go into effect on May 1, 1994, as currently stated in the permit. If you have any questions or comments regarding this issue, please feel free to contact me. cc: Central Files Steve Mauney 7.tera.

Box 27687 Raleigh, North Carolina 27611-7687 Re: NPDES No. NC0023299 Woodlake Mobile Home Park Guilford County Dear Mr. Overcash: We have received the Division of Environmental Managements April 19th "Notification of Intent" to reissue our NPDES permit for the Woodlake Waste Water Treatment Plant. As requested, we have reviewed the draft permit which was attached and find we have major concerns regarding the proposed permit and the discharge limit requirements. In fact, it was quite a shock when we examined the draft permit for its particulars. We found that the proposed discharge limitation on NH3 as N for the period beginning may 1, 1994 has a daily maximum but no monthly average for either the summer or winter portions of the permit. Applying the ratio obviously employed for the other discharge parameters, this would imply that a monthly average of .75 mg/1 for summer and .9 mg/1 for winter would be expected of us. We question the technical feasibility of this degree of nitrogen removal on a consistent basis. We further question the need for the low maximum daily limit shown. We, as a corporation, recognize our responsibilities to protect the environment. Your regional personnel are aware of the significant investment that has been made at the Woodlake Waste Water Treatment Plant over the past year to insure that we accomplish what is expected of us. However, after reviewing the proposed limits, we feel we have no recourse but to object to the% proposed permit for the period beginning May 1, 1994. Our primary objection is to the very stringent limitation on the BOD5 - NH3 respectively. A review of our file data indicates that the facility has met these limits, stringent though they are. Samples taken from the receiving stream at the plant indicate little or no reduction in the dissolved oxygen content of the stream due to the plant's discharge. To us this would indicate that we are successful in our objective of protecting the environment. Consequently, we fail to see a need for the more restrictive limits for these two elements of the permit. IV/AY 2 1iyJli We believe that the basis for the proposed limits is faulty. in ,,; technical staff has arbitrarily assigned 0 cfs flow to the jeceiving stream, even for the 3OQ2. We do no believe that any credit whatsover was given for the large body of water 100 feet upstream of the discharge point which could, if required, be employed to provide flow augmentation during dry conditions. Further, we have decided to embark on a comprehensive area watershed survey to determine the area size and general characteristics of the drainage basin available to the stream which serves the plant. If our belief is correct, then the wasteload allocation modelling does not accurately reflect the actual conditions of the stream and discharge point relationship. We have detected recently a general mood among some of the public and their regulators to eliminate the small "package" wastewater treatment plant. This may be a worthy objective, but until a feasible alternative is available to our customers, we have to continue to strive, as we have in the past, to provide them with a cost efficient operation while making our best effort to protect the environment at the same time. This is not an easy task, as you well know. Unrealistic and unnecessarily restrictive effluent limits only complicate the situation for everyone. Please advise us as to the required coarse of action we need to undertake since we cannot accept the proposed permit with the limitations as they are now proposed for the period beginning and following May 1, 1994.

Pay Permit # k/C(202319 CHRONIC TOXICITY TESTING REQUIREMENT (QRTRLY) The effluent discharge shall at no time exhibit chronic toxicity in any two consecutive toxicity tests, 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 ql % (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 issuance of this perrnit.during the months of Feb, May , kug, Nov. . Effluent sampling for this testing shall be performed at the NPDES permittedfinaleffluent 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 P.O. Box 27687 Raleigh, N.C. 27611 Test data shall becompleteand 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 altemate monitoring requirements or limits. NOTE: Failureto 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. 7Q10 • 0 <o cfs Permited Flow _ 0.07 MGD Recommended by: IWC% 100 Basin & Sub -basin 53c,60 Receiving Stream ur to Po feed Ctee k KeLd Sco "County Guy fi o r d Date 2(20 o **Chronic Toxicity (Ceriodaphnia) P/F at qi %, CD, May/ r�uj� Nou , See Part , Condition _. DIVISION OF ENVIRONMENTAL MANAGEMENT March 21,1990 MEMORANDUM TO: Dale Overcash THRU: Ruth Swanek 1X5 Trevor Clements FROM: Mike Scoville r SUBJECT: NPDES Permit Conditions for Woodlake Mobile Home Park NPDES No. NC0023299, Guilford County WLA Request No. 5593 Woodlake Mobile Home Park discharges to a unnamed tributary to Polecat Creek at a site where the 7Q10 and 30Q2 are both zero. In accordance to Division procedure for handling domestic discharges to zero -flow streams, the facility's limits should change three years after permit issuance (see WLA for specific conditions). As part of the implementation of the basin -wide permitting schedule, this permit will again be renewed in April 1991. It is my understanding that if the permit were to be issued at this time, it would possibly be for less than a twelve month period. Therefore, per discussion with Don Safrit, there is the likelihood that the Division will hold the permit and issue it next April. If the permit is held, the WLA is correct as is; the permit should be drafted in the normal manner. If a one-year permit is issued this year, the existing limits (A) should apply and the permit should include special con- ditions requiring an engineering report within twelve months of permit issu- ance and indicating to the permittee that the effluent limits will be chang- ing in the near future. If you have any questions or comments regarding this matter, please con- tact me.
