### Page 2 of 31 Executive Summary
Sodium and calcium hypochlorite, better known as bleach, were first registered for use as sanitizers and disinfectants of surfaces, as disinf ectants of water, and as chemicals to control microorganisms on certain foods and in certain industrial processes in 1957. Sodium and calcium hypochlorite are chlorina ted inorganic disinfectants used in laundries, swimming pools, ponds, drinking water, and other water and wast ewater systems; on f ood and non-food contact surfaces; and as a postharvest, seed or soil treatment on various fr uit and vegetable crops. Other specific use sites are commercial and industrial cooling tower and evaporative condenser water; hospital premises and contents; food processing plant equipment and premises; and toilet bowl and general household cleaners. The hypochlorite s control bacteria, fungi, and slime-forming algae. There are four hundred twenty-six products containing sodi um hypochlorite and 120 products containing calcium hypochlorite. The active ingredient decl arations range from 0.0095% to 35% sodium hypochlorite and from 0.542% to 73% calcium hypochlorite. The Agency has evaluated the existing product chemis try data base and has determined that no additional data are required fo r reregistration review; all prod uct chemistry data requirements have been satisfied for the active ingredie nts sodium and calcium hypochlorite salts.
Due to uniqueness of these two chemicals (bei ng inorganic pesticides ), conventional fate data is neither present nor required. The Agency has evaluated the existing chemical information and properties on sodium and calcium hypochlorites, their reaction product s and use patterns and has determined that no additional data are requir ed for reregistration review. The environmental fate of these compounds is complex but is know n based on inorganic a nd oxidation/reduction chemistry. Both sodium and calcium hypochlorite are highly reactive and except for commercial and industrial cooling tower and swimming pool a nd pond applications the existing application rates and use patterns are expected to be consum ed prior to any possible discharge or emission to the terrestrial or aquatic environments. Use pa tterns with potential nontarget exposure to total chlorine residue include commercia l and industrial cooling towers.
All ecological effects data requirements for sodium and calcium hypochlorite have been satisfied since the Registration Standard was issued in 1986. Upon reevaluating these data, EPA has concluded that the currently registered uses of the hypochlorites will not result in unreasonable adverse effect s to the environment.

### Page 3 of 31 Introduction
Sodium and calcium hypochlorite, better know n as bleach, are widely used compounds whose chemical and toxicological properties are extensively documented in published literature. These chemicals were first registered for use as pesticides in 1957. Four hundred twenty-six products containing sodium hypochlorite and 12 0 products containing calcium hypochlorite are currently registered which are lis ted in Table 1 and 2 in Appendix A, respectively. EPA issued a Registration Standard for sodium and calcium hypochlorite in February 1986. The Agency concluded that no additional scientif ic data would be necessary to register or reregister products that contain sodium hypochlorite declarations of 5.25% to 12 .5%, or calcium hypochlorite of 65% to 70%, as long as the pr oducts contain no other active i ngredients, contain no inert ingredients other than water, and bear Toxicity Category I la beling. EPA still supports these basic findings. A Reregistration Eligibility Deci sion (RED) was issued by EPA for sodium and calcium hypochlorite salts in February 1992 1



### . Sodium and calcium hypochlorites are chlori nated inorganic disinfectants. Sodium hypochlorite is normally sold only as a liquid while calcium hypochlorite is principally sold as a solid, powder, granular, or tabl et product. Manufacturing-use s odium hypochlorite and calcium hypochlorite products are 12.5% and 65% respectiv ely. Sodium and calcium hypochlorites are registered for use as terminal sanitizing rinses of food handling utensi ls, as sanitizers and disinfectants of surfaces, as disi nfectants of water, and as chemicals to control microorganisms on certain foods and in certain industrial processe s. For a detailed listing of the use patterns/use sites see Appendix A (Tables 3).

Use Patterns Current sodium and calcium hypochlorite e nd-use products are labeled for use as:

 sanitizers of surfaces (e.g., wooden butcher bl ocks, stainless steel t ops, concrete floors, tile walls); or

### All product chemistry data requirements have been satisfied for the active ingredients sodium and calcium hypochlorite (Source: Sodium and Calcium Hypochlorite Salts Registration Standard & RED).

### Page 6 of 31 B. Environmental Fate Summary

In order to understand the fa te of sodium and calcium hypochlorites in environmental media, a few general aspects of their behavior in aqueous medium is helpful. Critical to this is an understanding about chlorine and its interac tion with water and compounds in water.

 Chlorine is one of the most ve rsatile elements, particularly in regards to its reaction with oxygen. Chlorine can take on numerous oxidation states (+7, +5, +4, +3, +1, 0, and -1) 2



### . The following diagrams illustrate a number of facts regarding the oxidation state and reaction products with chlorine under acidic and basic conditions:

o a) From the highest oxidation state of chlorine in the perchlorate ion (ClO 4 - 

### ) of +7 to -1 in the chloride ion (Cl - 

### ) the reduction potentials 3 

### are such that the reactions take place spontaneously in acidic or basic aquatic medium; and

o b) The reverse reactions such as Cl - 

### (oxidation -1 state) to ClO 4 - 

### (chlorine oxidation state +7) are not spontaneous. Under acidic conditions : ClO 4 ‐

2 Oxidation state is a measure of the degree of oxidation of an atom which in turn represents the tendency to lose electrons present in the valence orbitals 3 Reduction potential is a measure of the tendency to acqu ire electrons. The more positive the redox potential is the greater the affinity the atom or chemic al entity has for accepting electrons and to be reduced and in turn oxidizes the other chemical entity involved in the redox reaction. The large, positive oxidations states indicated stored chemical potential energy. In a chemical reac tion the increase in oxidation state is known as oxidation; a decrease in oxidation state is known as reduction.

### o The acid dissociation constant (K diss 

### or K a 

### ) of HClO is 3.4 x 10 -8 

### (or pK a 4 

### = 7.7). Hence at any given time, the concentrati on of HClO is not very high, however, as it gets used up—more HClO is formed and so on. It also means that at pH 7.7, the ratio of HClO to ClO - 

### is 50:50, while at pH 7.2, 70% is HClO and 30% is ClO -



### .

### . The graphical data is converted into the numerical data on the percent of HClO and ClO -

### o Disinfection is more efficient at lower pH than at higher pH because HClO is a more efficient disinfectant than ClO - 

### , and as indicated above there is a higher proportion of HClO at lower pH than at higher pH values.

 It is ClO - 

### and/or HClO moieties that are the actives for sodium and calcium hypochlorites under environmental conditions between pH 4 and 11.

 Available chlorine (AC) is a measure of the equivalent weights of oxidizing agents, with chlorine gas as a basis— i.e ., normalizes chlorine-containing compounds to allow comparison of oxidizing potential. The c oncentration of hypochlorite (or any other oxidizing disinfectant) may be expressed as available ch lorine by determining the electrochemical equivalent amount of elemental chlorine (Cl 2 

### ) to that compound (USEPA 1986).

o A mole of chlorine gas reacts with water to form a mole of HClO and a mole of protons (or hydrogen ions) and a mole of chloride ions. The oxidation state of chlorine is 0 in chlorine gas, +1 in HClO and -1 in Cl -

Given that the molecular weight of these two comp ounds is respectively 74.5 and 143, pure preparations of the two compounds c ontain 95.8% and 99.2% AC—the AC per mole of the chemical divided by the mol ecular weight of the chemical (USEPA, 1986) (see the equations provide d in the following bullet).

 Chlorine in addition to provi ding disinfection or oxidation of microorganisms can be consumed by oxidation or subs titution reactions with inor ganic substances such as ammonia, iron, manganese, sulfides a nd some other organic substances ( e.g ., phenols).

 In the surface water and wa stewater streams possible tr ansformation products like chlorine, HOCl, ClO 3 -

Environmental Fate and Transport of Sodium Hypochlorite and Calcium Hypochlorite
Sodium hypochlorite is a very active substance and dissociat es immediately in water to produce OCl - 

### . Depending on the pH of the medium, it has the capability to go through chemical transformation to ClO 2 - 

### , Cl 2 

### , Cl - 

### and under highly acidic and basi c conditions it can chemically transform into ClO 3 - 

### and ClO 4 - 

### , depending under the oxidizing or reducing conditions of the medium. Thus a conventional way of looking at the environmental data (hydrolysis, aquatic photolysis, aerobic/anaerobic aquatic metabolism) is not possible and therefore such data is not required.
EPA completed a RED on Sodium and Ca lcium Hypochlorites in 1991 (USEPA, 1991) and did not require any e nvironmental fate data. EPA concl uded that the fate requirements for these chemicals can be considered satisfied based on the information provided in the1981 Ambient Water Quality Criteria for Chlorine (J. T obler, EPA; June 1981); the last revision to the Ambient Water Quality Criteri a for Chlorine occurred in 1984 (USEPA, 1985). These documents discuss reaction equations of chlorine, total chlorine residual (TCR), effects of TRC on aquatic organisms, and ambient water qu ality criteria for TRC. Dissipation and transformation chemistry of chlorine and the hyp ochlorites, in water a nd with inorganics and organic molecules is also discussed in the EPA Municipal Wastewat er Disinfection Design Manual (USEPA, 1986).
In 2007, the OECD published a Screening Info rmation Data Set (SIDS) on calcium hypochlorite (OECD, 2007) which also reviews ch lorine reactions; the document concludes that additional assessment on chlorinated by-products should be pursued. European Commission’s Health and Consumer Protection Directorate Gene ral through its Scientific Committee on Health

### Page 10 of 31 and Environmental Risks (SCHER) completed it s Risk Assessment Report (RAR) on Sodium Hypochlorite in 2008 (EU, 2008). This report conc luded generally sodium hypochlorite is a very reactive moiety and transforms into so many othe r substances fast, so an actual environmental risk assessment cannot be conducted; however for cer tain use scenarios ther e is the potential for formation of such substances like organi c halogens (AOX), haloacetic acids (HAA), and trihalomethanes (THM), for which effects on aquatic organisms can be assessed. These inorganic moieties like OCl - 

### , ClO 2 

### , and ClO 3 - 

### etc . in aqueous systems undergo changes by themselves, through pH changes, and hence Ag ency guidelines for environmental fate and transport cannot be used to evaluate their fate characteristics in media like water and soils/sediments.
All environmental fate information require ments for sodium and calcium hypochlorite and reaction products have been satisfied.

### Page 11 of 31 C. Ecological Effects Summary
A summary of ecological effects data that is available in-hous e is summarized in Table 8. The Ambient Water Quality Criteria for Chlorine – 1984 document contains a review of public literature on effects of chlorine (total residual chlorine) and base d on the data derives freshwater and saltwater organism acute and chronic water qu ality criteria. Currentambient water quality criteria for chlorine are based on the data in the 1984 document and the method for deriving water quality standards discussed in a 1986 Water Quality Document (USEPA, 1986).

 Freshwater Criterion Maximu m Concentration = 19 μg/L;

 Freshwater Criterion Continuous Concentration = 11 μg/L;

 Saltwater Criterion Maximum Concentration = 13 μg/L; and

 Saltwater Criterion Continuous Concentration = 7.5 μg/L
