PA File No. FL0026557-015-DW1P/MR 2 of 332,000 gallons; three reclaimed water ground storage tanks with a combined capacity of 12.0 million gallons;

and one high service pumping station. All disinfection is accomplished using liquid chlorination. The permitted capacity of the water reclamation facility will remain at 8.0 mgd until such time as the City establishes the actual reuse capacity of the master reuse service area to assimilate the reclaimed water throughout the area.

The solids treatment consists of four aerobic sludge digesters with a combined capacity of 2.8 million gallons, and two belt filter presses with a capacity of 2,000 pounds of dry residuals per hour. The stabilized residuals are land applied.

A dechlorination/reaeration facility is located at the Loyd Nursery south of Knights Griffin Road for additional treatment prior to discharge. Dechlorination is accomplished by the addition of sulfur dioxide.

Filter backwash will be drained to the treatment facility headworks. Ferric sulfate is injected into the plant process stream at the effluent end of splitter box with optional injection at the clarifier stilling wells to aid in phosphorous removal. Polymer chemical feed is available on a standby status for solids control. Effluent quality is continuously monitored 24 hours per day through the plant SCADA system for turbidity as a measure of TSS and chlorine residual as a measure of disinfection effectiveness. Effluent failing to meet Part III public access quality standards is directed to the reject storage system, the polishing/storage pond noted above, or to either the industrial user R002 or the surface water discharge D002 described below.

Effluent which does meet Part III quality standards is transferred to the Plant City public access Master Reuse

System R001 described below. The storage, discharge, and reject functions are controlled, sequenced and operated according to procedures set forth in the plant Operating Protocol in order to assure maximum reliability and safeguards on the quality of the reclaimed water. Plant alarm systems are monitored by plant operational personnel

24 hours per day through the plant SCADA system. Standby emergency power is provided by four generators, three auto start and one manual with a total capacity of 5686 KW.

DISPOSAL:

Surface Water Discharge: D-001 is inactive.

Surface Water Discharge: An existing 2.68 MGD annual average daily flow (AADF) permitted discharge to East

Short-term Methods for Estimating the Chronic Toxicity of Effluents and Receiving

Waters to Freshwater Organisms, 4th ed., EPA-821-R-02-013. Any deviation of the bioassay procedures outlined herein shall be submitted in writing to the Department for review and approval prior to use. In the event the above method is revised, the permittee shall conduct chronic toxicity testing in accordance with the revised method.

(4) The control water and dilution water shall be moderately hard water as described in EPA-821-

R-02-013, Section 7.

e. Quality Assurance Requirements

(1) A standard reference toxicant (SRT) quality assurance (QA) chronic toxicity test shall be conducted with each species used in the required toxicity tests either concurrently or initiated no more than 30 days before the date of each routine or additional follow-up test conducted.

Additionally, the SRT test must be conducted concurrently if the test organisms are obtained from outside the test laboratory unless the test organism supplier provides control chart data from at least the last five monthly chronic toxicity tests using the same reference toxicant and test conditions. If the organism supplier provides the required SRT data, the organism supplier’s SRT data and the test laboratory’s monthly SRT-QA data shall be included in the reports for each companion routine or additional follow-up test required.

(2) If the mortality in the control (0% effluent) exceeds 20% for either species in any test or does not meet “test acceptability criteria”, the test for that species (including the control) shall be invalidated and the test repeated. Test acceptability criteria for each species are defined in

EPA-821-R-02-013, Section 13.12 (Ceriodaphnia dubia) and Section 11.11 (Pimephales promelas). The repeat test shall begin within 21 days after the last day of the invalid test.

(3) If 100% mortality occurs in all effluent concentrations prior to the end of any test and the control mortality is less than 20% at that time, the test (including the control) shall be terminated with the conclusion that the test fails and constitutes non-compliance.

(4) Additional follow-up tests shall be evaluated for acceptability based on the observed dose-response relationship as required by EPA-821-R-02-013, Section 10.2.6., and the evaluation shall be included with the bioassay laboratory reports.

Temple Terrace, Florida 33637-0926

g. Test Failures

(1) A test fails when the test results do not meet the limits in 9.a.(1).

(2) Additional Follow-up Tests:

(a) If a routine test does not meet the chronic toxicity limitation in 9.a.(1) above, the permittee shall notify the Department at the address above within 21 days after the last day of the failed routine test and conduct two additional follow-up tests on each species that failed the test in accordance with 9.d.

PA File No. FL0026557-015-DW1P/MR 8

(b) The first test shall be initiated within 28 days after the last day of the failed routine test.

The remaining additional follow-up tests shall be conducted weekly thereafter until a total of two valid additional follow-up tests are completed.

(c) The first additional follow-up test shall be conducted using a control (0% effluent) and a minimum of five dilutions: 100%, 50%, 25%, 12.5%, and 6.25% effluent. The permittee may modify the dilution series in the second additional follow-up test to more accurately bracket the toxicity such that at least two dilutions above and two dilutions below the target concentration and a control (0% effluent) are run. All test results shall be statistically analyzed according to the Appendices in EPA-821-R-02-013.

(3) In the event of three valid test failures (whether routine or additional follow-up tests) within a

12-month period, the permittee shall notify the Department within 21 days after the last day of the third test failure.

(a) The permittee shall submit a plan for correction of the effluent toxicity within 60 days after the last day of the third test failure.

(b) The Department shall review and approve the plan before initiation.

(c) The plan shall be initiated within 30 days following the Department’s written approval of the plan.

(d) Progress reports shall be submitted quarterly to the Department at the address above.

(e) During the implementation of the plan, the permittee shall conduct quarterly routine whole effluent toxicity tests in accordance with 9.d. Additional follow-up tests are not required while the plan is in progress. Following completion or termination of the plan, the frequency of monitoring for routine and additional follow-up tests shall return to the schedule established in 9.b.(1). If a routine test is invalid according to the acceptance criteria in EPA-821-R-02-013, a repeat test shall be initiated within 21 days after the last day of the invalid routine test.

(f) Upon completion of four consecutive, valid routine tests that demonstrate compliance with the effluent limitation in 9.a.(1) above, the permittee may submit a written request to the Department to terminate the plan. The plan shall be terminated upon written verification by the Department that the facility has passed at least four consecutive valid routine whole effluent toxicity tests.

If a test within the sequence of the four is deemed invalid, but is replaced by a repeat valid test initiated within 21 days after the last day of the invalid test, the invalid test will not be counted against the requirement for four consecutive valid tests for the purpose of terminating the plan.

(4) If chronic toxicity test results indicate greater than 50% mortality within 96 hours in an effluent concentration equal to or less than the effluent concentration specified as the acute toxicity limit in 9.(1)(b), the Department may revise this permit to require acute definitive whole effluent toxicity testing.

(5) The additional follow-up testing and the plan do not preclude the Department taking enforcement action for acute or chronic whole effluent toxicity permit limit violations.

[62-4.241, 62-620.620(3)]

II. RESIDUALS MANAGEMENT REQUIREMENTS

1. The method of residuals use or disposal by this facility is land application, transport to an RMF or disposal in a Class I solid waste landfill. Transportation of the residuals to an RMF does not require a permit modification, however, use of an RMF requires a copy of the agreement pursuant to Chapter 62-

640.880(1)(c) along with a written notification to the Department at least 30 days before transport of the residuals.

2. The permittee shall be responsible for proper treatment, management, use, and land application or disposal of its residuals. [62-640.300(5)]

3. The permittee will not be held responsible for violations resulting from land application of residuals if the permittee can demonstrate that it has delivered residuals that meet the parameter concentrations and appropriate treatment requirements of this rule and the applier (e.g. hauler, contractor, site manager, or site owner) has legally agreed in writing to accept responsibility for proper land application of the residuals. Such an agreement shall state that the applier agrees, upon delivery of residuals that have been treated as required by Chapter 62-640, F.A.C., that he will accept responsibility for proper land application of the residuals as required by Chapter 62-640, F.A.C., and that the applier agrees that he is aware of and will comply with requirements for proper land application as described in the facility’s permit.

[62-640.300(5)]

4. The permittee shall not be held responsible for treatment, management, use, or land application violations that occur after its residuals have been accepted by a permitted residuals management facility with which the source facility has an agreement in accordance with Rule 62-640.880(1)(c), F.A.C., for further treatment, management, use or land application. [62-640.300(5)]

5. Disposal of residuals, septage, and other solids in a solid waste landfill, or disposal by placement on land for purposes other than soil conditioning or fertilization, such as at a monofill, surface impoundment, waste pile, or dedicated site, shall be in accordance with Chapter 62-701, F.A.C. [62-

640.100(6)(k)3 & 4]

6. Land application of residuals shall be in accordance with the conditions of this permit, the approved

Agricultural Use Plan(s), and the requirements of Chapter 62-640, F.A.C. [62-640]

7. The domestic wastewater residuals for this facility are classified as Class B.

8. The permittee shall achieve Class B pathogen reduction by meeting the pathogen reduction requirements in section 503.32(b)(2) (Alternative 1, Monitoring of Fecal Coliform) of Title 40 CFR

Part 503, revised as of October 25, 1995. [62-640.600(1)(b)]

PA File No. FL0026557-015-DW1P/MR 18

9. The permittee shall achieve vector attraction reduction by meeting the vector attraction reduction requirements in section 503.33(b)(10) (Incorporate biosolids applied to or placed on the land surface within specified time periods after application to or placement on the land surface) of Title 40 CFR

Part 503, revised as of October 25, 1995. [62-640.600(2)(a)]

10. Alternative 1 requires that seven samples of treated sewage sludge (biosolids) be collected over a 2-week period and that the geometric mean fecal coliform density of these samples be less than 2 million

CFU or MPN per gram of biosolids (dry weight basis). This approach uses fecal coliform density as an indicator of the average density of bacterial and viral pathogens. Over the long term, fecal coliform density is expected to correlate with bacterial and viral pathogen density in biosolids treated by biological treatment processes.

11. Treatment of liquid residuals or septage for the purpose of meeting the pathogen reduction or vector attraction reduction requirements set forth in Rule 62-640.600, F.A.C., shall not be conducted in the tank of a hauling vehicle. Treatment of residuals or septage for the purpose of meeting pathogen reduction or vector attraction reduction requirements shall take place at the permitted facility. [62-
