PART 4 - SPECIAL CONDITIONS

Section 1 - Additional Special Monitoring Requirements

The solids removal system and the ultraviolet oxidation unit were shut down in 2001 and eight weeks of sampling for volatile and semi-volatile organic compounds were collected. No semi-volatile organic compounds were detected in the eight-week sampling period other than an anomaly in the sixth week of sampling. Therefore, less frequent additional special monitoring requirements for the Central Groundwater Treatment Facility (CGWTF) were implemented. The new requirements began on May 9, 2001 (the day after the last of the eight-week sampling period was collected- May 8, 2001).

Vance AFB collected another round of eight weeks of samples between May 81 h and July 11, 2002 when the 2nd collection system was tied to the Central Groundwater Treatment Facility. The results were well within the TTO limits. There was an anomaly in the first week of sampling when the effluent results were higher than the influent results. This is probably a laboratory error. As per your request of October 25, 2004, the analytical results from the previous two (2) years identified all semi volatile results below detection limits. However, the only way to determine if there is break-through is to continue to monitor for this parameter. Therefore, less frequent additional special monitoring requirements for the Central Groundwater Treatment Facility (CGWTF) was implemented at that time. Vance AFB will sample the effluent at the CGWTF for semi-volatile organics once every six-(6) months to demonstrate compliance. Results will be reported twice/yr (January and July).

-9-

If any new monitoring well is added to the treatment process Vance AFB will sample the effluent at the CGWTF for volatile and semi-volatile organics once every week for two (2) consecutive months to demonstrate compliance with the TTO limit. The monitorin~ wells included in this list are any of the corrective measure sites or any well that is added to the 2" interceptor collection trench. Additional sampling would also be required for any new contaminated groundwater site that is hauled to the CGWTF. Vance AFB will submit the results of any new sampling events within two (2) weeks of receipt to the Environmental Specialist. If a result above the Practical Quantification Limit (PQL) is detected for any volatile or semi-volatile organic then the City will be notified immediately. The analyses will be reviewed and if a meeting is needed it will be scheduled with Vance AFB to discuss the findings.

If a problem develops at the POTW from the current groundwater treatment system or any new monitoring well or from hauled waste to the CGWTF, then the City of Enid may:1) require the groundwater remediation system to be shut down until the problem is corrected, and/or 2) establish more stringent limits for the groundwater treatment facility.

Two samples for BODs, TSS and NH3 must be collected and analyzed for every semi-annual report.

Section 2 - Reopener Clause

A. This permit may be reopened and modified to incorporate any new or revised requirements contained in a National Categorical Pretreatment Standards under 40 CFR.

B. This permit may be reopened and modified to incorporate any new or revised requirements resulting from the City of Enid re-evaluation of its local limits.

C. This permit may be reopened and modified to incorporate any new or revised requirements developed by the City of Enid as are necessary to ensure POTW compliance with all controlling agencies.

D. This permit may be reopened and modified to incorporate any mission change of Vance Air Force Base.

Overflows

The permittee shall give notice (report) any overflows (any wastewater spill or release) to the City of Enid (616-7302) within 24 hours from the time the permittee becomes aware of the overflow. It does not matter whether it is a small overflow (1 gallon or less) or a large overflow (greater than 1 million gallons), it still must be reported to the City of Enid (attention: Environmental Compliance Specialist).

The following shall be included as information which must be reported within 24 hours:

A. Any unanticipated bypass which exceeds any effluent limitation in the permit.

B. Any upset which exceeds any effluent limitation in the permit.

C. Any violation of a maximum daily discharge limit for any of the pollutants listed in the permit.

-10-

D. Any bypass in the collection system (sanitary sewer overflow (SSO)).

A written submission shall be provided within 5 working days of the time the permittee becomes aware of the overflow. The report shall contain the following information:

A. A description of the overflow and the cause.

B. The period of the overflow including exact dates and times, and if the overflow has not been corrected, the anticipated time it is expected to be corrected.

C. Steps being taken to immediately stop, contain, clean-up, reduce, eliminate and/or prevent recurrence of the overflow.

The City of Enid may also require the permittee to implement permanent corrective actions if the overflows occur too frequently.

PART 5 - STANDARD CONDITIONS

A. Severability The provisions of this permit are severable, and if any provision of this permit, or the application of any provision of this permit to any circumstance, is held invalid, the application of such provision to other circumstances, and the remainder of this permit shall not be affected thereby.

-13-

2. Composite Sample-A sample that is collected overtime, formed either by continuous sampling or by mixing discrete samples. The sample may be composited either as a time composite sample: composed of discrete sample aliquots collected in one container at a constant time interval providing representative samples irrespective of stream flow; or as a flow proportional composite sample: collected either as a constraint sample volume at time intervals proportional to stream flow, or collected by increasing the volume of each aliquot as the flow increases while maintaining a constant time interval between the aliquots.

3. Grab Sample-An individual sample collected in less than fifteen (15) minutes, without regard for flow or time.

4. Instantaneous Maximum Concentration-The maximum concentration allowed in any single grab sample.

5. Slug Load-Any pollutant (including BOD) released in a discharge at a flow rate or concentration which will cause a violation of the specific discharge prohibitions in 40 CFR 403.5(b) to 403.12(f).

6. Cooling Water-

a. Uncontaminated: Water used for cooling purposes only which has no direct contact with any raw material, intermediate, or final product and which does not contain a level of contaminants detectably higher than that of the intake water.

b. Contaminated: Water used for cooling purposes only which may become contaminated either through the use of water treatment chemicals used for corrosion inhibitors or biocides, and by direct contact with process materials and/or wastewater.

7. Monthly Average-The arithmetic mean of the values for effluent samples collected during a calendar month or specified 30-day period (as opposed to a rolling 30 day window).

8. Weekly Average-The arithmetic mean of the values for effluent samples collected over a period of seven (7) consecutive days.

9. Bi-Weekly-Once every other week.

11. Bi-Monthly-Once every other month.

12. Upset-Means an exceptional incident in which there is unintentional and temporary non-compliance with technology-based permit effluent limitations because of factors beyond the reasonable control of the permittee, excluding such factors as operational error, improperly designed or inadequate treatment facilities, or improper operational and maintenance or lack thereof.

SAMPLING PROCEDURES FOR SIGNIFICANT INDUSTRIAL USER'S (SIU's)

Sample description:

Composite samples for copper, mercury, silver, and zinc will be collected in the same sample bottle. A one (1) liter plastic bottle will be filled 1/4 full during each of the four (4) samples collected during the operating day. After each sample is taken it will be cooled and kept at 4 degrees Centigrade or 39 degrees Fahrenheit. At the end of the day there will be one (1) bottle, which will be preserved with HN03 to a pH less than 2. One sample result for each of the eight (8) metals listed will be reported in the self monitoring report.

Composite samples for BODs, TSS, and NH3 will be collected in the same one-liter plastic container during each sample. Four (4) samples will be collected during the operating day. After each sample is taken, it will be cooled and kept at 4 degrees Centigrade or 39 degrees Fahrenheit. One sample result for the BODs, TSS, and NH3 parameter will be reported in the self-monitoring report.

All grab samples will be collected one ( 1) time/day during the operating period. A grab sample for phenol will be collected in at least a 500 ml glass container with a teflon lid. A grab sample for oil and grease will be collected in a one-liter glass wide mouth container with a teflon lid. One (1) grab sample will be collected for each parameter during the operating day. After the phenol and oil and grease samples are taken they will be cooled and kept at 4 degrees Centigrade or 39 degrees Fahrenheit. Phenols and oil and grease will be preserved with H2S04 to a pH less than 2. Phenols and oil and grease will be reported in the self-monitoring report.
