E. Description of Wastewater Treatment Facilities Once-through condenser cooling wzter for all three units (outfalls 001, 002, and 005) and nuclear auxiliary cooling water (outfall 006) is passed through bar racks and intake screens, chlorinated (except outfall 006), and discharged to the site discharge canal. Water used to sluice ash from Units 1 and 2 is treated in ash ponds (outfalls 004 and 009) with effluent to the site discharge canal.

Rainfall runoff from the coal pile is treated in a pond which in-frequently discharges to adjacent tidal marshes (outfall 008). Debris from the intake canal is disposed of by landfill and wash water is returned to the plant intake canal (outfalls 010A,010B and 011). Evaporation / percolation ponds are provided for all other wastes from Units 1 and 2. Non-radioactive wastes and radiation waste from Unit 3 (outfalls 003 and 007) are treated by neutralization, settling, filtration and/or oil removal and discharged to Outfall 006, or on-site percolation ponds.

NOTE: The radioactive component of the Unit 3 discharges is regulated by the U.S. Nuclear Regulatory Commission under the Atomic Energy Act, and not by the USEPA under the Clean Water Act.

Other Pertinent Information The Crystal River generating facility is located adjacent to Crystal Bay, an estuarine nursery area between the community of Crystal River and the Cross Florida Barge Canal. At this facility, the Florida Power Corporation operates five generating units. Historically these units were placed into operation in the following sequence: Unit 1,1966; Unit 2,1969; Unit 3,1977; Unit 4,1982; and Unit 5,1984 Units 4 and 5 employ closed cycle cooling with the use of natural draft cooling towers: Units 1,2, and 3 use helper cooling towers. A combined daily Cow of 1898 MGD is required for the cooling systems of the two coal-fired units (Units 1 and 2) and the nuclear unit (Unit 3). Approximately 50 percent of the total flow is directed to the nuclear unit. Water for the once-through mode of operation is drafted from an intake channel extending westwardly into Crystal Bay. Separating the intake channel from the discharge area of the facility is a seven-mile long dike which flanks the northern side of the intake channel. This channel also serves barge traffic for the delivery of coal to the plant site.

Heated water from the condenser cooling systems is returned to the bay on the northern side of the seven-mile dike.

3. BASIS FOR EFFLUENT LIMITATIONS AND PERMIT CONDITIONS i

l The majority of the effluent limitations and conditions for permitting contained in Part I of the permit are continuations of those provisions in the previous NPDES permit.

These conditions were made in accordance with the following regulations and determinations:

15 i

l

I l

A. Federal effluent guidelines for the steam electric power generating point source 1

category (40 CFR Part 423, November 19,1982,47 FR 52290), New Source Performance Standards (f 423.15). A best professionaljudgment (BPJ) has been made that concentration limitations will be used in lieu of mass limitations in accordance with 40 CFR f 423.15(m). All measurement frequency and sample type requirements are based on BPJ. A limitation on pH range of 6.0 standard units minimu n and 9.0 maximum has been proposed in accordance with 40 CFR f 423.15(a), except when limited for direct discharge. For direct discharge, the pH 2

range is limited to 6.0 to 8.5 in accordance with FAC Section 62-302.560(21).

Where necessary, limitations and monitoring requirements have been established for internal waste streams (e.g., wastes which combine with other contaminated wastes or cooling water prior to discharge) in accordance with 40 CFR f122.45(h). Unless otherwise noted, the reason for designating internal waste i streams is that the required pollutant concentration limitations cannot be l monitored after combination, due to dilution.

B. Florida Water Quality Standards: The receiving waters are classified as Surface Waters, Class III Waters Recreation, Propagation, and Maintenance of a Healthy, Well-Balanced Population of Fish and Wildlife (FAC Chapters62-301 and 62-302).

Requirements for toxic pollutants are provided in FAC Sections62-302.200,62-302.500, and 62-302,560. "All surface waters of the State shall at all places and at all times be free from domestic, industrial, agricultural, or other man-induced non-thermal components of discharges which, alone or in combination with other substances or in combination with other components of discharges (whether thermal  ;

or non-thermal) are acutely toxic {Section 62-302.500(1)(d)]." " Acute Toxicity" is defined in Section C-302.200(1) as: "the presence of one or more substances or characteristics or components of substances in amounts which: (a) are greater than one-third (1/3) of the amount lethal to 50% of the test organisms in 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> (96 hr LC50) where the % hr LC50 is the lowest value which has been determined for a species significant to the indigenous aquatic community; or (b) may reasonably be expected, based upon evaluation by generally accepted scientific methods, to produce effects equal to those of the concentration of the substance specified in (a) above." Criteria for specific pollutants are contained in Section 62-302.530.

i i

1 FR - Federal Register 2

FAC - Florida Administrative Code 16 I

l C. Sections 316(a) and 316(b) of the Clean Water Act (CWA): The thermal l component of the discharge is subject to compliance with Florida water quahty l standards (FAC 62-302). Notwithstanding these requirements, Section 316(a) of the CWA allows the Regional Administrator to impose alternative and less stringent thermal limitations after demonstration that the water quality standards limitations are more stringent than necessary to assure the protection and propagation of a balanced, indigenous population of fish and wildlife in, and on, the receiving waters. Section 316(b) requires that the location, design, construction, and capacity of a cooling water intake structure reDect the best technology available for minimizing environmental impacts.

On December 31,1974, EPA issued a permit to the Florida Power Corporation (FPC) for the Crystal River Power Plant, Units 1,2, and 3, which allow required off-stream cooling subject to consideration of a variance and alternative i limits under (316(a). Since the Agency found that adequate data were not available to determine whether alternative limits for the thermal component could be allowed, the 5316(a) determination was deferred pending the completion of adequate engineering and biological studies. FPC requested an adjudicatory hearing on the permit in January,1975.

In settlement of the hearing request, EPA issued a modified permit on July 9, 1979, with an effective date of July 23,1979, and an expiration date of February 1980. The Florida Department of Environmental Regulation (FDER) certified the permit on February 7,1979. The modified permit imposed a discharge flow limitation of 100 MGD, subject to implementation or modification consistent with the Regional Administrator's final #316 determination. The permit also contained a schedule of compliance which required thermal / biological post-operational monitoring and f316(a) and 6316(b) studies. Further, the permit stated that based on these studies, the Regional Administrator shall make a determination as to the possible need for procedure modification, facility construction, reduced thermal discharge, or reduced intake flow.

In January 1985, FPC submitted its final report of the Q316(a) and s316(b) studies which were required by its July 23,1979, modified permit, and which were conducted from June 1983 to August 1984. Results of the studies showed suf0cient adverse biological effects were associated with the citing and operating of Crystal River Units 1,2, and 3. The f316(a) study demonstrated that the existing thermal discharge caused substantial damage in Crystal Bay in violation of the existing Florida water quality standards (FAC Section 62-3.05(1)(a)). The level of entrainment and impingement demonstrated by the 316(b) study constituted an adverse impact to the biota of Crystal Bay and environs.

17 i

w Os

! FPC submitted a proposal for certain mitigation measures on August 21,1986.

These included: creation of marshes, planting of seagrasses, construction and operation of a hatchery, and implementation of a monitoring program. On January 23,1987, FPC submitted an alternative proposal to extend the existing discharge canal. Additional information regarding that proposal was provided on April 17,1987, comprising the installation of helper cooling towers (i.e, only a portion of the plant's heated effluent is cooled and returned to the discharge canal where it mixes with the remainder of uncooled effluent),

reduction of intake flow, and hatchery construction and operation. The proposal was modified on March 1,1988, to include a seagrass inonitoring and planting program, and a limitation on plant operations to maintain a three-hour I average temperature not to exceed 96.5 F and an instantaneous maximum temperature not to exceed 97.0 F.

Recardine EPA's Previous 6316fa) determination: The FPC proposal to install helper cooling towers are expected to return the discharge area to the i approximate thermal levels in existence prior to the operation of Unit 3 (beginning in 1977). It should be noted that the determination also stated that the helper cooling towers would not reduce the present intake flow or the entrainment of aquatic organisms associated with the flow. However, the proposed reduction in plant intake flow during the months of November through April would proportionately reduce entrainment during that period. (Installation of closed cycle cooling towers could reduce entrainment damage by about 85 %,

however, the increased cost was considered to be wholly disproportionate to the  !

environmental benefits to be derived.)

Becardinc EPA's Previous 6316(b) determination: The intakes of the Crystal River Power Plant are located in an estuarine nursery area. The capacity of Units 1,2 and 3, based on a once-through cooling mode is 1898 MGD. There are no design features incorporated in the facility which would minimize impact of the large volume of flow and poor location. The location, capacity and design of Crystal River Units 1,2 and 3 do not reflect the best technology available for minimizing adverse impacts as required by s316(b) of the CWA.

To minimize the adverse impact of the plant intake structures, installation of fine mesh screen and a return mechanism would constitute best available technology. However, such a modification was not considered to be technically feasible, due to the use of the intake canal for coal delivery. Ambient silt from the Gulf of Mexico, which settles in the intake canal and is re-suspended by coal barges, would collect on the intake screens (0.5 mm mesh would be necessary to remove fish eggs and larvae). Even if silt did not clog the screens and render them inoperable, return of the removed solids to Salt Creek (necessary for l return of aquatic organisms at the Crystal River site) would cause unacceptable siltation in the small creek. No other practical technological modification of the

(

cooling water intake structures is available which would minimize the 1 18

o.'  ;

l environmental impacts to an acceptable level. Therefore, it was concluded that a reduction of plant flow by 15 percent during the months of November through l April, in conjunction with the construction and operation of a fish hatchery over l the remaining operating life of the three units constituted minimization of the environmental impacts of the cooling water intake.

Based on a re-evaluation of the previous f316(a) and (b) studies, the Department feels that the prior determinations are still valid.

Inclusion oflimits for the parameters are based on the previous NPDES permit and information in the permit application. The previous NPDES permit allowed the limits to be met at the edge of a State-granted mixing zone, which was authorized in a State-issued operating permit. The mixing zones are no longer authorized in any State-issued operating permit; therefore, these parameters must now be met at the point of discharge, rather than at the edge of a mixing zone.

a. Authorization for use of Amertap bal's at Units 1 and 2. (see condition 1.1.)

b. Deletion of the instantaneous maxi'aum temperature limit of 97 'F at the POD.

c. Authorization to use and discharge Spectrus CT1300 and Spectrus DT1401 at D-0F.

(see condition I.A.5. and I.B.13)

d. Deletion of authorization to 6scharge and monitoring requirements for ethanolamine .

e. Authorization to desigr.att D-01 [formerly (OSN) 015)] as the POD.

(see condition I.A.10.d.)

f. Authorization to move the injection point of DT1401 to at least 70 feet prior to discharge downstream of CT1300 injection point. (see condition 1.B.13.c).

The permit incorporates changes made by the permit writer based on historical data provided by the facility and best professional judgment of the following:

a. Deletion of tl'e limitations and monitoring for total residual oxidants (TRO) and time of TRO discharge at D-0F (formerly OSN 006). The change was made because TR O and time of TRO discharge are monitored at D-013 (formerly OSN 005) located upstream of D-0F and chlorination at D-0F is not authorized.

b. The discl.arge limitations for hydrazine, hydroquinone, ammonia (as N), and morphotine at D-0F were either increased or decreased according to toxicity test data provided by the facility. (see condition I.A.4) 23

c. The discharge limitations for oil and grease at I-FE, D-0F [at the Condensate l System (CD) and Evaporator Condensate Storage Tank (ECST)], and I-FG are pursuant to 40 CFR Section 423.12(b)(3). The discharge limitations for oil and grease are more stringent for direct discharges which are located further downstream in order to ensure compliance.

d. Additional discharge limit parameters for oil and grease, pH, turbidity and total j suspended solids were added to the tables of D-0C1, D-0C2, D-OF, D-0H, D-071, D-072 and D-0J to ensure compliance with specific requirements.

e. An additional discharge limitation parameter table for D-0F was added specifically to ensure compliance with the authorization to use Spectrus CT1300 and Spectrus DT1401 at Unit 3. (see condition I.A.5) 1

f. The toxicity testing requirement for Copper-trol at D-013 was deleted pursuant to historical toxicity data provided by the facility which documented compliance and no adverse affect to the environment.
