December 19, 2008 Honorable Jan Throgmorton City of West Fork P.O. Box 339 West Fork, Arkansas 72774 RE: West Fork Wastewater Treatment Plant Inspections AFIN: 72-00137 NPDES Permit No.: AR0022373 Dear Mayor Throgmorton: On November 25, 2008, I performed a compliance sampling inspection of the wastewater treatment plant, and on December 3, 2008, I performed a routine permit compliance evaluation inspection of the facility. These inspections were conducted in accordance with the provisions of the Federal Clean Water Act, the Arkansas Water and Air Pollution Control Act, and the regulations promulgated thereunder. These inspections revealed the following: Permit Compliance Evaluation Inspection: 1. Violations of Part II, Section C.2 of your permit: a. Although effluent samples are collected after final treatment at the dechlorination pond discharge point, flow is measured before the pond after the chlorine contact chamber. As the flow rate into the pond can differ from the flow rate discharging from the pond (for example, due to precipitation), monthly mass loading determinations may not reflect the actual loading on the receiving stream. Flow measurement devices must be installed at the monitoring point of the discharge. b. Absence of a head reference point in the 60 degree v-notch weir. This must be installed at a distance upstream from the weir crest at a distance of three to four times the maximum head expected over the weir. Currently, head is being measured within the v-notch from the base of the notch to the liquid level directly above the notch. Because drawdown occurs at this point, flow rate determination is inaccurate. 2. Violations of Part II, Section C.3 of your permit: a. Duplicate samples are not being analyzed on least 10% of the effluent samples. The consulting laboratory provides the sample bottles to the wastewater treatment plant. No duplicate bottles are provided to the plant. The plant operators collect the samples and deliver them to the laboratory. Although the consulting laboratory

December 19, 2008 Honorable Jan Throgmorton City of West Fork P.O. Box 339 West Fork, Arkansas 72774 RE: West Fork Wastewater Treatment Plant Inspections AFIN: 72-00137 NPDES Permit No.: AR0022373 Dear Mayor Throgmorton: On November 25, 2008, I performed a compliance sampling inspection of the wastewater treatment plant, and on December 3, 2008, I performed a routine permit compliance evaluation inspection of the facility. These inspections were conducted in accordance with the provisions of the Federal Clean Water Act, the Arkansas Water and Air Pollution Control Act, and the regulations promulgated thereunder. These inspections revealed the following: Permit Compliance Evaluation Inspection:

1. Violations of Part II, Section C.2 of your permit:

a. Although effluent samples are collected after final treatment at the dechlorination pond discharge point, flow is measured before the pond after the chlorine contact chamber. As the flow rate into the pond can differ from the flow rate discharging from the pond (for example, due to precipitation), monthly mass loading determinations may not reflect the actual loading on the receiving stream. Flow measurement devices must be installed at the monitoring point of the discharge.

b. Absence of a head reference point in the 60 degree v-notch weir. This must be

installed at a distance upstream from the weir crest at a distance of three to four times the maximum head expected over the weir. Currently, head is being measured within the v-notch from the base of the notch to the liquid level directly above the notch. Because drawdown occurs at this point, flow rate determination is inaccurate.

2. Violations of Part II, Section C.3 of your permit:

a. Duplicate samples are not being analyzed on least 10% of the effluent samples. The

consulting laboratory provides the sample bottles to the wastewater treatment plant. No duplicate bottles are provided to the plant. The plant operators collect the samples and deliver them to the laboratory. Although the consulting laboratory

indicates in the analytical results reports that duplicates have been run on all samples, these results are reflective of split samples, not duplicate samples as required.

b. All buffers for pH meter calibration are expired. c. Sample temperatures when received by the consulting laboratory are not less than or

equal to 6 degrees C as required by 40 CFR 136. Sample analytical reports for August, September, and October 2008 were reviewed. Sample temperatures when received into the laboratory for these months were 8 degrees C, 8 degrees C, and 10 degrees C, respectively.

3. Violations of Part II, Section C.8 of your permit:

a. Records of effluent samples preservation methods are incomplete. Preservation

methods, other than with ice, are not indicated on the chain-of-custody forms for ammonia nitrogen, total phosphorus, and fecal coliform bacteria. Preservation methods are not listed in the sample analytical results reports.

b. Exact effluent sampling location is not recorded. The sampling location is not indicated on the chain-of-custody forms. Samples are listed as “effluent” on the analytical reports.

4. Wastewater from a West Fork daycare center is pumped directly into the equalization basin,

bypassing the grit chamber. This is in violation of Part II, Section B.4 of your permit. 5. Fencing along the southwest perimeter was damaged by flooding and has been in a state of

disrepair for several years. This condition does not meet the requirements of the “Recommended Standards for Wastewater Facilities”. The Arkansas Department of Pollution Control and Ecology Commission, in Minute Order 80-21, adopted the “Recommended Standards for Wastewater Facilities” (commonly known as the 10-States Standards) developed by the Great Lakes-Upper Mississippi River Board of State and Provincial Public Health and Environmental Managers. 10-States Standards item 57.1.a states “Enclosure of the plant site with a fence and signs designed to discourage the entrance of unauthorized persons and animals” shall be provided to effectively protect plant personnel and visitors from hazards.

Compliance Sampling Inspection:

• The analytical results for the samples collected during the inspection reveal that each parameter met the effluent limitations for monthly average, 7-day average and mass loading. However, because flow is not measured at the monitoring point of the discharge as required by the permit, the calculated mass loading may not reflect the actual mass loading on the receiving stream.

Compliance Sampling Inspection (CSI): The analytical results for the samples collected during the inspection reveal that each parameter met the effluent limitations for monthly average, 7-day average and mass loading. However, because flow is not measured at the monitoring point of the discharge as required by the permit, the calculated mass loading may not reflect the actual mass loading on the receiving stream.

Response to Inspection Dear Mayor Throgmorton: The Department has received your response to the recent inspection of your facility on November 25, 2008 by our District Field Inspector, John Fazio. Your responses to items 2 and 5 are satisfactory, but we will need further information about the reasons flow cannot be measured after the dechlorination lagoon. We also need to know the size of the dechlorination lagoon, as well as, the exact location of where the effluent samples are taken. The sampling location must be indicated on the chain-of-custody forms. It is also the determination of the Department that the wastewater from the West Fork daycare center cannot flow into the Flow Equalization/Emergency Holding Lagoon. This flow must tie into the main and go through the entire treatment process and cannot bypass the Grit Chamber. Please update the Department on the specific progress you make regarding these matters. Your response should reach the Department no later than February 28, 2009. The Department will keep the inspection and response on file and will consider them as required by the Pollution Control and Ecology Commission Regulation No. 7, Civil Penalties. This regulation requires the Department to take into consideration the past history of your facility and how expeditiously violations were addressed in determining any civil penalty that may be necessary for any violations. If we need further information, we will contact you. Thank you for your attention to this matter. Should you have any questions, feel free to contact me by phone at 501-682-0823 or e-mail at [email protected]. Sincerely,

Dawn Keller Enforcement Administrator Water Enforcement Section cc: Eric Fleming

March 20, 2009 The Honorable Jan Throgmorton City West Fork P.O. Box 339 West Fork, AR 72774 RE: NPDES Permit AR0022373 AFIN 72-00137 Dear Mayor Throgmorton: The Department has received your response to the letter dated January 30, 2009. It has been determined that a V-notch weir must be constructed at the dechlorination lagoon discharge point located at the northwest corner of the lagoon. It has further been determined that an engineer must be hired to supervise the installation of the weir at the facility. Part II, Section C, Paragraph 2 of the Permit states “Appropriate flow measurement devices and methods consistent with accepted scientific practices shall be selected and used to insure the accuracy and reliability of measurements of the volume of monitored discharges. The devices shall be installed, calibrated, and maintained to insure the accuracy of the measurements are consistent with the accepted capability of that type of device. Devices selected shall be capable of measuring flows with a maximum deviation of less than +/- 10% from true discharge rates throughout the range of expected discharge volumes and shall be installed at the monitoring point of the discharge.” Please update the Department on the specific progress you make regarding these matters. Your response should reach the Department no later than April 10, 2009. The Department will keep the response on file and will consider them as required by the Pollution Control and Ecology Commission Regulation No. 7, Civil Penalties.
