Subject:

Catawba Nuclear Station -NPDES Permit No. SC0004278-Steam Generator Chemical Metal Cleaning File: CN-208.20 Certified: 068 519 062

Dear Mr. Eleazer:

This letter is being written to request a one time approval to discharge a maintenance compound used to chemically clean the steam generators. In May 1994 Duke Power Company will perform a steam generator chemical cleaning. Four steam generators for Catawba Unit 2 will be cleaned during this process.

Treatment Chemicals Ethylenediamine (EDA) and ammonium carbonate (NH )4 2CO 3 have been selected as the treatment chemicals to use for the cleaning. These compounds have been selected to attack the copper and iron build up within the steam generator and not to attack the base metals.

EDA is less aggressive than the more commonly used chemical of EDTA (diammonium salt). The EDTA has been commonly used for this type of cleaning and if used would yield significantly higher concentrations of copper and iron in the resulting wastewater.

Please find attached information on EDA and ammonia carbonate required by the permit (Part III, item 9) which is necessary to obtain approval.

Wastewater Treatment Temporary treatment equipment will be used to treat this wastewater prior to discharge. A separate submittal will be made to describe t

CNS Steam Generator Cleaning {

the temporary _ treatment in order to obtain the necessary State approvals. Prior to finalizing the temporary treatment system design, .it is necessary to know if additional monitoring above the existing permit requirements is going to be imposed.

As a result of this cleaning approximately 40,000 gallons- (0.04 MG) of liquid waste will be generated. The approximate composition of this -waste will be 3% by weight ammonium carbonate- (NH )2CO , -3 3 % by -

4 weight ethylenediamine (EDA), 400 ppm copper,'50 ppm iron, and.the-balanced deionized water. The wastewater will be slightly radioactive.

Prior to any treatment, the waste will be analyzed to determine if it.is hazardous. Upon determining that the waste is non7 hazardous it will be treated to comply with the effluent limits contained in '

the NPDES permit for this facility.

t The liquid waste will be processed through internal outfall 004 and then to Lake Wylie by means of outfall 001. Outfall 004 has  !

permit limits of 1 ppm for copper and 1 ppm for~ iron.

Precipitation by chemical coagulation coupled with filtration is i the anticipated process to be used to remove the metals prior to ,

discharge. The process would be-composed of chemical addition '

equipment, coagulation / settling tank, filter press, and a monitor i tank. Each tank would be sampled and analyzed to verify compliance prior to discharge. Along with existing limits,- the pH at outfall 001 will be maintained between 6.0 and 8.0.

Attached to this memo please find a flow diagram describing the work to be performed. j Summary 3

i Duke Power is requesting approval to use EDA and ammonium carbonate ,

for use in chemically cleaning the steam generators-for Unit 2. i Additionally, it is requested that the State determine if any additional monitoring will be imposed due to this discharge. Duke Power will then finalize our treatment system and submit the  ;

necessary information to the State for review.

If you need additional information or have any questions please. -i call John Estridge at (704) 875-5965.

Sincerely, ohn Carter, Technical System Manager Environmental Division, Water Protection jte/270 l

a) Ethylenediamine '(EDA) b) Ammonium Carbonate (NH. ) 2CO 3

2) QUANTITIES TO BE USED ,

40,000 gallons of a solution of approximately 3% EDA and 3%

Ammonium Carbonate will be used for the cleaning.

3) FREQUENCY OF USE This compound will be used for a single chemical' metal cleaning of the steam generators for Catawba Unit #2.

4) PROPOSED DISCHARGE CONCENTRATION

• The discharge at Outfall 004 will be less than 1.0 ppm iron, and 1.0 ppm copper.

The Discharge'at Outfall 001 will have a pH between 6.0 and 8.0. The EDA concentration will be less than 1.0 mg/1, Total

• ammonia will be maintained less than 1.0 mg/1.

5) EPA REGISTRATION NUMBER a) Ethylenediamine. CAS# 000107-15-3 l b) Ammonium Carbonate. CAS#506-87-6

6) AQUATIC TOXICITY INFORMATION

-a) Ethylenediamine.

Acute LC50 Daphnia magna (water flea) 0.88-16 mg/l

• Pimephales promelas (Fathead Minnow) 116-220 mg/l b) Ammonium carbonate.

When mixed with water, ammonium carbonate dissociates to ammonia and carbonate. Chronic Daphnid toxicity to unionized i ammonia has been reported to vary from 0.3 to'1.2 mg/1.

The toxicity of total ammonia (mg/l NH 3 ) is typically higher than that of unionized ammonia. Please see the attached EPA

SUMMARY

All concentrations used herein are expressed as un-ionized ammonia (NH3 ), because NH 3 , not the ammonium ion (NH4 +) has been demonstrated to be the principal toxic form of ammonia. The data used in deriving criteria are predominantly from flow through tests in which ammonia concentrations were measured.

Ammonia was reported to be acutely toxic to freshwater organisms at concentrations (uncorrected for pH) ranging from 0.53 to 22.8 mg/L NH3 for 19 invertebrate species representing 14 fam'i lies and 16 genera and from 0.083 to 4.60 mg/L NH3 for 29 fish species ,

from'9 families and 18 genera. Among fish species, reported 96-hour LC50 ranged from 0.083 to 1.09 mg/L for salmonids and from 0.14 to 4.60 mg/L NH 3 for nonsalmonids. Reported data from' chronic tests on ammonia with two freshwater invertebrate species, both daphnids, showed M s at co h ations

[

(uncorrected for pH) ranging f om 0.304 to 1.2 mg/L NH 3 nd with nine freshwater fish species, from five families and seven genera, ranging from 0.0017 to 0.612 mg/L NH3.

Concentrations of ammonia acutely toxic to fishes may cause loss of equilibrium, hyperexcitability, increased breathing, ,

cardiac output and oxygen uptake, and, in extreme cases, convulsions, coma, and death. At lower concentrations ammonia has many effects on fishes, including a reduction in hatching success, reduction in growth rate and morphological development, and pathologic changes in tissues of gills, livers, and kidneys.

Several f actors have been shown to modify acuto NH 3 toxicity (

in fresh water. Some factors alter the concentration of un-ionized ammonia in the water by affecting the ageous ammonia equilibrium, and some factors affect the toxicity of un-ionized ammonia itself, either ameliorating or exacerbating the effects of ammonia. Factors that have been shown to affect ammonia toxicity include dissolved oxygen concentration, temperature, pH, previous acclimation to ammonia, fluctuating or intermittent exposures, carbon dioxide concentration, sal inity, and the .

presence of ot..er toxicants. gd g

The most well-studied of these is pH; the acute toxicity of gd /

NH 3 has been shown to increase as pH decreases. Sufficient data N Y exist from toxicity tests conducted at different pH values to N gN formulate a mathematical expression to describe pH-dependent b acute NH 3 toxicity.

The very limited amount of data regarding effects of pH on chronic NH 3 toxicity also indicates increasing NH 3 toxicity with decreasing.pH, but the data are insufficient to derive a broadly applicable toxicity /pH relationt.. Data on temperature effects on acute NH 3 toxicity are limited and somewhat variable, but indications are that NH 3 toxicity to fish is greater as temperature decreases. There is no information available regarding temperature effects on chronic NH toxicity.

3 Examination of pH and temperature-corrected acuto NH 3 toxicity values among species and genera of freshwater organisms showed that invertebrates are generally more tolorant than fishes, a notable exception being the fingernail clam. There is no clear trend among groups of fish; the several most sensitive .

J tested species and genera include representatives from diverse familles (Salmonidae, Cyprinidae, Porcidae,- and Contra rchidae),

i Availabic chronic toxicity. data for freshwater organisms also indicate invertebrates (cladocerans, one insect specien) to be more tolerant than fishes, again with the exception of the l fingernail clam. When corrected for the presumed effects of temperature and pH, there is also no clear trend among groups of fish for chronic toxicity values, the most sensitive species I including representatives from five families (Salmonidae, i

Cyprinidae, Ictaluridae, Centrarchidae, and Catostomidae) and 4

having chronic values ranging by not much more than a fa'ctor or ,

two.

The range of acute-chronic ratios for lo species from 6 families was 3 to 43, and acute-chronic ration were higher for the species having chronic tolerance below the median.

Available data indicato that differences in sensitivities between warm and coldwater families of aquatic organisms are inadequate to warrant discrimination in the national ammonia critorion between bodies of water with " warm" and "coldwatier" fishes; rather, effects of organism sensitivities on the criterion are most appropriately handled by site-specific criteria derivation procedures.

toxic to freshwater phytoplankton and vascular plants, although limited, indicate i that. freshwater piant specio's are appreciably more tolerant to l

NH 3 than are invertebratos or fishes.

The ammonia criterion' appropriate for the protection of aquatic animals will therefore t

in all likelihood be sufficiently protective of plant life.

).

Available acute and chronic data for ammonia with saltwater I organisms are very limited, and insufficient to derive.a saltwater critorion. A few saltwater invertebrato species have been tested, and the prawn Macrobrachium rosenbergii was the most sensitive. The few saltwater fishes tested suggest greater sensitivity than freshwater fishes. Acute toxicity of NII 3 appears to be greator at low pH values, similar to findings in freshwater. Data for saltwater plant species are limited to diatoms, which appear to be more sensitive than the saltwater invertebrates for which data are available.

More quantitative information needs to be published on the toxicity of ammonia to aquatic life. Several key research needs must be addrocsed to provide a more complete assessment of ammonia toxicity. These are: (1) acute tests with additional saltwater fish species and saltwater invertebrate species; (2) life-cycle and early life-stage tests with representative freshwater and saltwater organisms from different families, with particular attention to trends of acute-chronic ratios; (3) fluctuating and intermittent exposure tests with a variety of species and exposure. patterns; (4) more complete tests of the individual and combined effects of pH and temperature, especially for chronic toxicity; (5) more histopathological and histochemical research with fishes, which'would provide a rapid means of identifying and quantifying sublethal ammonia etfects; and (6) studies on effects of dissolved and suspended solids on acute and chronic toxicity.

I' NATIONAL CRITERIA:

I The proceduros described in the Guidelines for Deriving Humorical National Water Quality Criteria for the Protection of Aquatic Organisms and Their Usos indicate that, except possibly where a locally importa'nt species is very sensitive, freshwater aquatic organisms and their uses should not be affected unacceptably if:

(1) the 1-hour

• average concentration of un-ionized ammonia (in ug/L NH3 ) does not exceed, more often than.once every 3 years on the averago, the numerical value given by 0.52/FT/FPH/2, where: '

period may be needed.) .

(*Because these formulas are nonlinear in pH and temperature, the criterion should be the average of separate evaluations of the formulas reflective of th'e fluctuations of flow, pH, and temperature within the averaging period; it is not appropriate',in general to simply apply the formula to average pH, temperature, and f1 ow.)

r The extremes for temperature (0, 30) and pH- (6.5, 9) given in the above formulas -are absolute. It is not permissible with  ;

current data to conduct any extrapolations beyond these limits.

In particular, there is reason to believe that appropriate criteria at pH > 9 will be lower than the plateau between pH 8 and 9 given above.

Criteria concentrations for the .pH range 6.5 to 9.0 and the temperature range O C'to 30 C are provided in the following tables. Total ammonia concentrations equivalent to each un-ionized ammonia concentration are also provided in these tables.

There are limited data on the effect of temperature on chronic toxicity. EPA will be conducting additional research.on the effects of temperature on ammonia toxicity in order to ,f i l l perceived data gaps. Because of this uncertainty, additional site-specific information should be developed before these so a PLssstes 01 Wasa aa:sT E661-82-330

( 1 critoria aro used in wastoload allocation modeling. Foi examplo, s

the chronic criteria tabulated for sites lacking salmonids are less certain at temperatures much below 20 C than those tabulated at temperatures near 20 C.

Where the treatment lovels needed to meet those criteria below 20 C may be substantial, use of site-specific criteria is strongly suggested. Developmont of such critoria should be based upon site-specific toxicity tests.

Data available for saltvater species are insufficient to derivo a criterion for saltwater.

The recommended exceedence frequency of 3 years is the Agency's best scientific judgment of the average amount of time it will take an unstressed system to recover from a pollution event in which exposure to ammonia exceeds the criterion. A stressed system, for example, one in which several outfalls occur in a limited area, would be expected to require more time for recovery. The resilience of ecosystems and their ability to recover differ greatly, however, and site-specific criteria may be established if adequato justification is provided.

The use of criteria in designing waste treatment facilities requires the selection 'of an appropriate wasteload allocation model. Dynamic models are preferrod for the application of these criteria. Limited data or other factors may make their use impractical, in which case one should rely on a steady-state model.

The Agency recommends the interim use of 1Q5 or lQlO for i

Criterion Maximum ~ Concentration design flow and 7Q5 or 7QlO for the Criterion Continuous concentration design flow in steady-state models for unstressed and stressed systems respectively.

The Agency acknowledges that the critorion continuous b Concentration stream flow averaging period used for steady-state (

wasteload allocation modeling may be-as long as-30 days in situations involving POTWs designed to remove ammonia where limited variability of ef fluent pollutant concentration and resultant concentrations in receiving waters can, be demonstrated.

In cases where low variability can be demonstrated, longer averaging periods for the ammonia criterion continuous concentration (e.g., 30-day averaging periods) would be acceptable because the magnitude and duration of exceedences the criterion continuous concentration would be
