Toxicological Profile of Benzene CAS #: 71 43 2 Physical/ Chemical Properties Boiling Point: 80.1 deg   C Form: Clear, colorless liquid; Rhombic prisms Solubility: 0.180 g/ 100 g of water at 25 deg   C; miscible with alcohol, chloroform, ether, carbon disulfide, acetone, oils, carbon tetrachloride, and glacial acetic acid. OSHA PEL: 8 hr time weighted average ( TWA) of 1 ppm and a short term exposure limit ( STEL) of 5 ppm.

Chronic Toxicity Chronic exposure may result in delayed hematopoietic changes, including aplastic anemia, acute myeloblastic leukemia, and erythroleukemia. Other hematological disorders possibly associated with benzene exposure include Hodgkin's disease, lymphocytic lymphoma, myelofibrosis and myeloid metaplasia, paroxysmal nocturnal hemoglobinuria, and multiple myeloma. Chronic benzene toxicity is expressed as bone marrow depression resulting in leucopenia, anemia, or thrombocytopenia ( Leukemogenic action). With continued exposure the disease may progress to pancytopenia resulting from bone marrow aplasia. Evidence has accumulated implicating benzene in the etiology of leukemias in workers in industries where benzene is heavily used. It has been suggested that leukemia is as frequent a cause of death from chronic benzene exposure as is aplastic anemia. Chronic exposure to benzene usually involves the inhalation of vapor. Signs and symptoms incl effects on central nervous system ( CNS) & the gastrointestinal ( GI) tract ( headache, loss of appetite, drowsiness, nervousness, & pallor), but the major manifestation of toxicity is aplastic anemia. Bone marrow cells in early stages of development are most sensitive & arrest of maturation leads to gradual depletion of circulating cells.

Carcinogenicity Based on the Iris database, benzene has an A classification ( Human carcinogen).

Basis for classification: Several studies of increased incidence of nonlymphocytic leukemia from occupational exposure, increased incidence of neoplasia in rats and mice exposed by inhalation and gavage, and some supporting data form the basis for this classification.

NIOSH recommends that the benzene be treated as a potential human carcinogen. Risk Based Concentrations Carcinogenic Potency Slope Oral ( risk per mg/ kg/ day): 2.9 E 02 I Carcinogenic Potency Slope Inhalation ( risk per mg/ kg/ day): 2.9E 02 I Reference Dose Oral ( mg/ kg/ day): Not established Reference Dose Inhalation ( mg/ kg/ day): 1.7 E 03 E Toxicity Concern Chronic Toxicity: High Concern Carcinogenicity: High Concern ( Human Carcinogen) OSHA rating: A1: Confirmed Human Carcinogen ( ACGIH) Page 3 Fate Profile for Tetrachloroethylene CAS #: 127 18 4 Fate in Soil If released to soil, tetrachloroethylene ( PCE) will evaporate fairly rapidly into the atmosphere due to its high vapor pressure and low adsorption to soil. It can leach rapidly through sandy soil and therefore may reach groundwater. Biodegradation may be an important process in anaerobic soils based on laboratory tests with methanogenic columns. Slow biodegradation may occur in groundwater where acclimated populations of microorganisms exist. PCE should not hydrolyze under normal environmental conditions.

Fate in Water If tetrachloroethylene ( PCE) is released in water, the primary loss will be by evaporation. The half life for evaporation from water will depend on wind and mixing conditions and is estimated to range from 3 hours to 14 days in rivers, lakes and ponds. Chemical and biological degradation are expected to be very slow. PCE will not be expected to significantly bioconcentrate in aquatic organisms or to adsorb to sediment.

A mesocosm experiment was conducted to simulate Narraganset Bay during different seasons. Volatilization was the major removal process during all seasons and seasonal differences can be explained by hydrodynamics and the measured half lives were 25 days in spring, 11 days in winter and 14 days in summer. PCE will be subject to rapid volatilization with estimated half lives ranging from < 1 day to several weeks. It will not be expected to significantly biodegrade, bioconcentrate in aquatic organisms or significantly adsorb to sediment. PCE will not be expected to significantly hydrolyze in soil or water under normal environmental conditions.

Fate in Air If released to the atmosphere, tetrachloroethylene ( PCE) will exist mainly in the gas phase, based upon a reported vapor pressure of 18.47 mm Hg at 25 deg ° C. Vapor phase PCE will be expected to degrade by reaction with photochemically produced hydroxyl radicals or chlorine atoms produced by photooxidation of PCE. Estimated photooxidation time scales range from an approximate half life of 2 months to complete degradation in an hour. Some of the PCE in the atmosphere may be subject to washout in rain based on the solubility of PCE in water; PCE has been detected in rain.

OSHA PEL: > 200 ppm ( but never > 300 ppm) only for a maximum period of 5 minutes in any 3 hours. Not to exceed a time weighted average of 100 ppm during an 8 hr period.

Chronic Toxicity Chronic exposure may affect the liver and kidneys; cause arrhythmias; reduced color perception; contact dermatitis and defatting dermatitis; impaired memory; numbness of the extremities, and peripheral neuropathy; central nervous system ( CNS) effects; vertigo and impaired vision. Chronic inhalation exposure has been associated with the development of peripheral neuropathies. Chronic occupational exposure may result in chromosome abnormalities in lymphocytes, hepatitis, confusion, disorientation, muscle cramps, fatigue, and agitation. Chronic exposure of 60 to 450 ppm has caused CNS effects in workers. Tetrachloroethylene excretion in breast milk has been associated with obstructive jaundice in newborn infants.

Carcinogenicity Based on IARC: There is limited evidence in humans for the carcinogenicity of tetrachloroethylene. There is sufficient evidence in experimental animals for the carcinogenicity of tetrachloroethylene.

Overall evaluation: Tetrachloroethylene is probably carcinogenic to humans ( Group 2A). In making the overall evaluation, the working group considered the following evidence:

( 1) Although tetrachloroethylene is known to induce peroxisome proliferation in mouse liver, a poor quantitative correlation was seen between peroxisome proliferation and tumor formation in the liver after administration of tetrachloroethylene by inhalation. The spectrum of mutations in proto oncogenes in liver tumors from mice treated with tetrachloroethylene is different from that in liver tumors from mice treated with trichloroethylene. Page 5 ( 2) The compound induced leukemia in rats.

( 3) Several epidemiological studies showed elevated risks for esophageal cancer, non Hodgkin's lymphoma, urinary tract tumors, lukemia and cervical cancer.

NIOSH has recommended that tetrachloroethylene be treated as a potential human carcinogen.

This adsorption results in high concentrations of sorbed ammonia in oxidized sediments. Under anoxic conditions, the adsorptive capacity of sediments is less, resulting in the release of ammonia to either the water column or an oxidized sediment layer above.

Fate in Water If released to water, the proportion of the ammonia ( NH 3) and ammonium ion found in water and used for production is considered an important indicator of quality in agriculture. In highly populated fish breeding plants, where feed left overs, excrement and metabolic waste cause growth disturbances and deficiencies, even though there is an adequate supply of oxygen, nitrogen compound are the decisive factor. A significant role is played by the undissociated NH 3 molecule. Experiments have been carried out both with and without ventilation and using varying amounts of fish feed. The concentration of NH 3, which depends on pH and temperature, was investigated to determine the extent of the oxidative change of NH 3 through NO 3 during the mineralization process of the feed leftovers. Under the conditions used in the 2 sets of experiments there was hardly any tendency for the pH values in the unventilated experiments to alter and become more alkaline from an ammonification of leftover feed. In the experiments using ventilation, the proteins underwent an especially intensive process of decomposition, ie, they became completely mineralized, and considerable amounts of NH 4 N and NH 3 N were released. Due to the lack of organic acids, these could not be neutralized and, as a result, the pH value increased.

Fate in Air If released to air, it is assumed that ammonia combines with sulfate ion in the atmosphere or in washout by rainfall resulting in a rapid return of ammonia to the soil. Page 7 Toxicological Profile of Ammonia CAS #: 7664 41 7 Physical/ Chemical Properties Boiling Point:  33.35 deg   C Form: Colorless gas Solubility: Soluble in chloroform & ether; 31% in water @ 25 deg   C; 11% in absolute alcohol at 30 deg   C; 10% in ethanol at 25 deg   C. OSHA PEL: 50 ppm; 35 mg/ cu m Chronic Toxicity Chronic effects via inhalation may cause a chronic cough, asthma, or lung fibrosis. Also, calcification and epithelial proliferation of the renal tubules, congestion of the kidneys, and degenerative changes in the suprarenal glands has been reported in animals. Animals exposed via inhalation exhibited signs of congestion of spleens, livers, and kidneys with early degenerative changes in suprarenal glands. Ammonia toxicity is a major factor in the pathogenesis of hepatic encephalopathy associated with chronic liver disease.

Carcinogenicity No data regarding the carcinogenic effects in humans was found at the time of this review.

The largest anthropogenic source of methanol release to the environment is evaporation from solvent uses ( 1.1 billion lb/ yr).

Fate in Soil If released to soil, methanol is expected to degrade via biodegradation and be susceptible to significant leaching. Methanol is expected to be biodegradable in soil based on the results of a large number of biological screening studies, which include soil microcosm studies. Its miscibility in water and log Kow ( 0.77) suggest high mobility in soil. Based on a vapor pressure of 92 mm Hg at 20 deg ° C, evaporation from dry surfaces can be expected to occur.

Fate in Water If released to water, decomposition via biodegradation is expected to occur. Aquatic hydrolysis, oxidation, photolysis, adsorption to sediment, and bioconcentration are not significant.

Methanol has an measured Henry's Law Constant of 4.4X10 6 atm cu m/ mole at 25 deg   C. This value of Henry's Law Constant indicates that volatilization from environmental waters may be significant. The volatilization half life from a river ( 1 meter deep flowing 1 m/ sec with a wind speed of 3 m/ sec) has been be 4.8 days. The volatilization half life from model pond has been estimated to be 51.7 days.

Fate in Air If released to the atmosphere, methanol degrades via reaction with photochemically produced hydroxyl radicals with an approximate half life of 17.8 days. Methanol is expected to exist almost entirely in the vapor phase in the ambient atmosphere, based on a vapor pressure of 92 mm Hg at 20 deg   C. Atmospheric methanol can also react with nitrogen dioxide in polluted air to yield methyl nitrite. Because of methanol's water solubility, rain would be expected to physically remove some from the air; the detection of methanol in a thunderstorm water tends to confirm this supposition. Page 9 Toxicological Profile of Methanol CAS #: 67 56 1 Physical/ Chemical Properties Boiling Point: 64.7 deg   C Form: Colorless liquid Solubility: Soluble in acetone, chloroform; miscible with water, ethanol, ether, benzene, most organic solvents and ketones. OSHA PEL: 8 hr Time Weighted avg: 200 ppm; 260 mg/ cu m Chronic Toxicity Chronic poisoning from repeated exposure to vapor may be manifested by conjunctivitis, headache, giddiness, insomnia, gastric disturbances, & failure of vision. There may also be irreversible brain damage. Effects have been seen from either of the 2 most common routes of occupational exposure: inhalation and percutaneous absorption. Methanol has been found to be teratogenic in mice and rats. Chronic combined exposure to methanol and carbon monoxide has been reported as a causative factor of cerebral atherosclerosis.

Carcinogenicity No data regarding the carcinogenic effect in humans was found at the time of this review.

This chemical is not expected to bioconcentrate in the food chain.

Fate in Soil If released to soil, dichloromethane is expected to evaporate from near surface soil into the atmosphere because of its high vapor pressure. Although little work has been done on its adsorptivity, it is probable that it will leach through subsoil into groundwater. Hydrolysis in soil is not an important process under normal environmental conditions.

Fate in Water If released to air, dichloromethane has a high Henry's Law coefficient and will evaporate moderately rapidly from water. Dichloromethane will be primarily lost by evaporation to the atmosphere which should take 3 5.6 hours depending on wind and mixing conditions. Hydrolysis in groundwater is not an important process under normal environmental conditions. Degradation in groundwater is unknown.

Fate in Air If released to air, most of the dichloromethane will degrade by reaction with photochemically produced hydroxyl radicals with a half life of a few months. It will be subject to direct photolysis. Releases to water will primarily be removed by evaporation. When released into a river, dichloromethane levels were non detectable 3 15 miles from the source. Biodegradation is possible in natural waters but will probably be very slow compared with evaporation. It will not be expected to significantly adsorb to sediment or to bioconcentration in aquatic organisms. Page 11 Toxicological Profile of Methylene Chloride ( Dichloromethane) CAS #: 75 09 2 Physical/ Chemical Properties Boiling Point: 39.75 deg   C Form: Colorless liquid Solubility: Miscible with dimethylformamide OSHA PEL: 1000 ppm ( but never above 2000 ppm) only for a maximum period of 5 min in any 2 hr; not to exceed a time weighted average of 500 ppm for an 8 hr period.

Chronic Toxicity Chronic effects of methylene chloride may cause dermatitis on prolonged exposure. May increase the development of toxic encephalosis, acoustical and optical delusions, halucinations, memory loss with intellectual impairment, and bilateral temporal lobe degeneration due to carbon monoxide formation from dichloromethane. Dichloromethane has been seen to absorb through the placenta and may be found in the embryonic tissues following exposure of the mother; it can also excreted via milk. In rats, gerbils and hamsters exposed chronically through inhalation, the following clinical effects were noted: increased number of sarcomas located in or around the salivary glands, increase in benign mammary tumors, lung and liver tumors, decreased amyloidosis observed in the liver and other organs, decreased levels of glutamate, gamma aminobutyric acid, hepatocellular vacuolization, and phosphoethanolamine in the frontal verebral cortex, while glutamine and gamma aminobutyric acid are elevated in the posterior cerebellar vermis. Increases in the concn of dichloromethane ( DCM) to lower the oxygen affinity of human hemoglobin.

Carcinogenicity Based on the Iris database, methylene chloride has a B2 classification ( probable human carcinogen).

Basis for classification: Based on inadequate human data and sufficient evidence of carcinogenicity in animals; increased incidence of hepatocellular neoplasms and alveolar/ bronchiolar neoplasms in male and female mice, and increased incidence of benign mammary tumors in both sexes of rats, salivary gland sarcomas in male rats and leukemia in female rats. This classification is supported by some positive genotoxicity data, although results in mammalian systems are generally negative. Page 12 Human carcinogenicity data: Inadequate. Animal carcinogenicity data: Sufficient.

OSHA rating: A3: Animal Carcinogen ( ACGIH) Page 13 Fate Profile for Propylene Oxide CAS #: 75 56 9 Fate in Soil If released to soil, propylene oxide is expected to be susceptible to leaching and chemical hydrolysis in moist soils. It is expected to evaporate relatively rapidly from dry soil surfaces; evaporation from wet soils may also occur, but at a rate diminished by leaching. The estimated Koc values of 3.6 and 30 indicate that propylene oxide is expected to be very mobile in soil. The relatively high vapor pressure of propylene oxide, 439 mm Hg at 20 deg ° C, suggest that it should evaporate rapidly from dry soil surfaces.

Fate in Water If released to water, propylene oxide will hydrolyze at estimated half life rates of 11.6 days ( at pH's 7 9) and 6.6 days ( at pH 5) at 25 deg ° C. The presence of chloride ( Cl) ions accelerate the degradation in water and the chemical degradation half lives in seawater are estimated to be 4.1 days ( at pH's 7 9) and 1.5 days ( at pH 5) at 25 deg ° C. Reaction of propylene oxide with Cl ion in water yields approximately 90% 1 chloro 2 propanol and 10% 2 chloro 1 propanol as products under neutral pH conditions.

Volatilization of propylene oxide from the aquatic environment may be an important transport mechanism as the calculated half life from a model river 1 m deep flowing at 1 m/ sec with a wind velocity of 3 m/ sec is 10 hr at 20 deg ° C and the calculated half life from a representative oligotrophic lake is 18 days at 20 deg ° C. Adsorption to sediment, bioconcentration in aquatic organisms and reaction with photochemically produced hydroxyl radicals in water are not expected to be environmentally important fate processes as the estimated half life at room temperature is 9.15 years.

Fate in Air If released to the atmosphere, propylene oxide will react in the vapor phase with photochemically produced hydroxyl radicals with an estimated half life of approximately 30 days. Atmospheric removal by rainfall may occur. Page 14 Toxicological Profile of Propylene Oxide CAS #: 75 56 9 Physical/ Chemical Properties Boiling Point: 34.23 deg   C Form: Colorless liquid Solubility: Water solubility = 590,000 mg/ l @ 25 deg   C; miscible with acetone, benzene, carbon tetrachloride, methanol, & ether. OSHA PEL: 100 ppm; 240 mg/ cu m Chronic Toxicity Prolonged and/ or repeated dermal contact may cause defatting of the skin and dermatitis. Chronic effects may include neuropathy which has been reported in experimental animals. Exposure of man to propylene oxide mainly occurs through inhalation at the workplace. Because of the alkylating nature of propylene oxide, the formation of DNA adducts, the positive response in vitro mutagenesis assays, the carcinogenic effects in animals at the sites of entry into the body, and the absence of adequate data on cancer in human beings  propylene oxide should be regarded as if it presented a carcinogenic risk for man, and levels in the environment should be kept as low as feasible.

Carcinogenicity Based on the Iris database, propylene oxide has a B2 classification ( probable human carcinogen).

Basis for classification: Based on inadequate human data and an increased incidence of benign and malignant tumors at the site of exposure in two species of animals, when exposed by subcutaneous injection, by inhalation, and by gavage. Sarcomas occurred at injection sites, and nasal and gastrointestinal ( GI) cancers occurred with chronic exposure in animals. There was also evidence of mutagenicity in a variety of test systems. Propylene oxide is structurally similar to other chemicals that demonstrate carcinogenic activity in animals.

Human carcinogenicity data: Inadequate. Animal carcinogenicity data: Sufficient. Page 15 Risk Based Concentrations Carcinogenic Potency Slope Oral ( risk per mg/ kg/ day): 2.4E 01 I Carcinogenic Potency Slope Inhalation ( risk per mg/ kg/ day): 1.29E 02 I Reference Dose Oral ( mg/ kg/ day): No data Reference Dose Inhalation ( mg/ kg/ day): 8.57E 03 I Toxicity Concern Chronic Toxicity: High Concern Carcinogenicity: Probable Human Carcinogen OSHA rating: A3: Animal Carcinogen ( ACGIH) Page 16 Fate Profile for Phenol CAS #: 108 95 2 Overview Since phenol is a benchmark chemical for biodegradability studies, there is a large body of information on its degradation which concludes that phenol rapidly degrades in sewage, soil, fresh water and seawater. If released to the environment, phenol's primary removal mechanism is biodegradation which is generally rapid ( days). Acclimation of resident populations of microorganisms is rapid. Under anaerobic conditions degradation is slower and microbial adaptation periods longer.

Fate in Soil If phenol is released to soil, it will readily leach and biodegrade. The biodegradation in soil is generally rapid with half lives of under 5 days even in subsurface soils. Biodegradation is sufficiently rapid that most groundwater is generally free of this pollutant. The exception would be in the cases of spills where high concentrations of phenol destroy degrading microbial populations. Phenol's vapor pressure, 0.350 mm Hg at 25 deg ° C and low adsorptivity to soil indicate that volatilization from dry soil and other surfaces may occur.

Fate in Water If released to water, biodegradation is also the primary removal process for phenol released into water ( half lives are of the order of hours to days) although sensitized photolysis may also be important. In one study using estuarine water, the combination of biodegradation and photolysis resulted in a half life in summer and winter of 39 and 94 hr, respectively. Since the pKa of phenol is 9.994, it will be partially dissociated at higher pHs in water and moist soils and its transport and reactivity may be pH dependent. Phenol does not bioconcentrate in aquatic organisms.

The Henry's Law constant of phenol is 3.33X10 7 atm cu m/ mole. Based on this Henry's Law constant, the volatilization half life from a model river ( 1 m deep, flowing 1 m/ sec, wind velocity of 3 m/ sec) is estimated to be 107 days. The liquid phase transfer coefficient for phenol relative to oxygen was measured to be 0.01 in a laboratory reactor. Using the oxygen reaeration rate for a river, 0.04 1/ hr, the volatilization half life would be 72 days. Page 17 Fate in Air If released to the atmosphere, phenol occurs as a vapor and reacts with photochemically produced hydroxyl radicals resulting in a half life of approximately 15 hours. During the nighttime, it reacts with nitrate radicals with a resulting half life of 12 minutes. Phenol has also been shown to be readily removed from the atmosphere by rain. Page 18 Toxicological Profile of Phenol CAS #: 108 95 2 Physical/ Chemical Properties Boiling Point: 181.8 deg   C Form: Colorless to light pink, interlaced, or separate, needleshaped crystals, or a light pink, crystalline mass. Solubility: Very soluble in alcohol, chloroform, ether, glycerol, petrolatum, carbon disulfide, volatile and fixed oils, aqueous alkali hydroxides; very soluble in carbon tetrachloride, methyl alcohol, acetic acid, liquid sulfur dioxide; almost insoluble in petroleum ether; 93,000 mg in 1 L water at 25 deg   C; soluble in 1 g/ 12 ml benzene. OSHA PEL: 5 ppm; 19 mg/ cu m Chronic Toxicity Protracted or chronic exposure may result in major damage to the liver, kidneys and eyes; parenchymatous nephritis, hyperemia, nephritis, edema of the convoluted tubules, and degenerative changes of the glomeruli. Chronic exposure may also cause death from liver and kidney damage. Chronic systemic absorption of phenol may cause gray discoloration of the sclera with brown spost near the insertion of rectus muscle tendons, associated with blue or brown discoloration of the tendons over the knuckles of the hands. This is a form of ochronosis, known as carbolochronosis. Phenol is not a very volatile compound, consequently, most toxic effects occur from dermal and oral exposure.

Carcinogenicity Based on the Iris database, acetone has a D classification ( not classifiable as to human carcinogenicity).

Basis for classification: Based on no human carcinogenicity data and inadequate animal data.

Human carcinogenicity data: None. Animal carcinogenicity data: Inadequate.

Fate in Soil If released to soil, nonylphenol will have no mobility, based upon a high estimated Koc. Biodegradation of nonylphenol in aerobic soils may occur. Volatilization of nonylphenol should not be important from moist soil surfaces given an experimental Henry's Law constant of 2.45X10 9 atm cu m/ mole, and from dry soil surfaces based on a vapor pressure of 9.4X10 5 mm Hg. Limited data from sludge amended soil studies indicates that nonylphenol may undergo aerobic biodegradation in soil with approximately 10% degradadtion observed in 40 days.

Fate in Water If released to water, nonylphenol should strongly adsorb to suspended solids and sediment. It may bioconcentrate in fish and aquatic organisms. In the upper layers of surface water, nonylphenol may undergo sensitized photolysis. It may also biodegrade in aerobic waters, but is not expected to volatilize from water to the atmosphere. Nonylphenol may volatilize from water surfaces based on a Henry's Law constant of 9.4X10 5 atm cu m/ mole. Estimated volatilization half lives for a model river and model lake are 20,000 days and 160,000 days, respectively. An estimated BCF value of 24,000, from an estimated log Kow, suggests that nonylphenol will bioconcentrate in aquatic organisms according to a recommended classification scheme. Nonylphenol is expected to undergo sensitized photolysis in surface water. It was found to biodegrade in a river die away study and when incubated with stream and pond water samples.

Fate in Air If released to the atmosphere, nonylphenol will exist predominately in the particulate phase. It may be removed from the air by dry deposition.

Fate in Soil If released to soil or water, 1 amino 2 propanol is expected to degrade via biodegradation. Based upon an estimated Koc of 7.1, 1 amino 2 propanol is expected to leach readily in soil. The importance of leaching may be lessened by concurrent biodegradation. Based upon a vapor pressure of 0.47 mm Hg at 25 deg ° C, 1 amino 2 propanol should evaporate slowly from dry surfaces.

Fate in Water If released to water, the Henry's Law constant for 1 amino 2 propanol can be estimated to be 2.34X10 10 atm cu m/ mole using a structure estimation method; this value of Henry's Law constant indicates that a compound is essentially non volatile from water.

Fate in Air If released to the atmosphere, it will degrade relatively rapidly by reaction with photochemically produced hydroxyl radicals ( estimated half life of 9.9 hr). Based upon a vapor pressure of 0.47 mm Hg at 25 deg ° C, 1 amino 2 propanol is expected to exist almost entirely in the vapor phase in the ambient atmosphere.

Page 29 Fate Profile of Sodium Chromate CAS #: 7775 11 3 Overview Hexavalent chromium rarely occurs in nature, apart from anthropogenic sources, because it is readily reduced by oxidizable organic matter. Chromium ( VI) is mobile in ground water and sometimes used as a tracer to follow ground water flows.

Fate in Soil If released to soil, most soil chromium is in mineral, absorbed, or precipitated form. Chromium probably occurs as the insoluble Cr( III) oxide ( Cr2O3. nH2O) in soil, as the organic matter in soil is expected to reduce any soluble chromate to insoluble chromic oxide ( Cr2O3). Chromium in soil can be transported to the atmosphere by way of aerosol formation. Chromium is also transported from soil through runoff and leaching of water. Runoff could remove both chromium ions and bulk precipitates of chromium, with final deposition on either a different land area or a water body. In addition, flooding of soils and the subsequent anaerobic decomposition of plant matter may increase dissolution of Cr( III) oxides in the soil.

Fate in Water If released to water, hexavalent chromium frequently remains unchanged in many natural water sources because of a low concentration of reducing matter. Chromium( VI) exists in solution as hydrochromate, chromate, and dichromate ionic species. The proportion of each ion in solution is dependent on pH. In strongly basic and neutral pHs, the chromate form predominates. As the pH is lowered, the hydrochromate concentration increases. At very low pHs, the dichromate species predominates. In the pH ranges encountered in natural water, the predominant forms are hydrochromate ions ( 63.6%) at pH 6.0 to 6.2 and chromate ions ( 95.7%) at pH 7.8 to 8.5. The oxidizing ability of Cr( VI) in aqueous solution is pH dependent.

Although most of the soluble chromium in surface waters may be present as Cr( VI), a small amount may be present as Cr( III) organic complexes. Hexavalent chromium is the major stable form of chromium in seawater; however, Cr( VI) may be reduced to Cr( III) by organic matter present in water, and may eventually deposit in sediments.

Because there are no known chromium compounds that can volatilize from water, transport of chromium from water to the atmosphere is not likely other than by transport by windblown sea sprays. It has been estimated that the residence time of chromium inlake water is in the range of Page 30 4.6 to 18 years.

Fate Air If released to air, Cr( VI) in air may react with particulate matter or gaseous pollutants to form Cr( III). However, these atmospheric reactions have not been extensively studied. Chromium is removed from air through wet and dry depositions.

Solubility: 873 g/ L water at 30 deg   C; 3.44 g/ L methanol at 25 deg   C. OSHA PEL: Ceiling limit: 0.1 mg( CrO3)/ cu m Chronic Toxicity No data regarding the chronic effects was found at the time of this review.

Carcinogenicity Based on the Iris database, sodium chromate has a A classification ( human carcinogen).

Basis for classification: Results of occupational epidemiologic studies of chromium exposed workers are consistent across investigators and study populations. Dose response relationships have been established for chromium exposure and lung cancer. Chromium exposed workers are exposed to both cromium III and chromium VI compounds. Because only chromium VI has been found to be carcinogenic in animal studies, however, it was concluded that only chromium VI be classified as a human carcinogen.

Human carcinogenicity data: Sufficient.

Notice of Preliminary Permit Application Accepted for Filing and
Soliciting Comments, Motions To Intervene, and Competing Applications:
kW River Hydroelectric

    On March 4, 2019, kW River Hydroelectric filed an application for a
preliminary permit, pursuant to section 4(f) of the Federal Power Act
(FPA), proposing to study the feasibility of the Hamilton Low Dam
Hydroelectric Project to be located on the Great Miami River and near
the City of Fairfield, in Butler County, Ohio. The sole purpose of a
preliminary permit, if issued, is to grant the permit holder priority
to file a license application during the permit term. A preliminary
permit does not authorize the permit holder to perform any land-
disturbing activities or otherwise enter upon lands or waters owned by
others without the owners' express permission.
    The proposed project would consist of the following: (1) Eleven 37-
foot-long by 15-foot-wide turbine modules, each containing four 125-
kilowatt (kW) turbines for a total project capacity of 5,500 kW; (2)
two three-phase alternating current (A/C) generators, having a combined
maximum power output capacity of 7,500 kW; (3) a 240-foot-long, 69-kV
transmission line connecting to an existing transmission system
(preferred option) or a 110-foot-long, 13.2-kV line connecting to an
existing distribution system (secondary option); and (4) appurtenant
facilities. The estimated annual generation of the Hamilton Low Dam
Hydroelectric Project would be 3,066 megawatt-hours.

registration form (see 40 CFR 49.160). The National O&NG FIP also has
requirements relating to protected resources, and, in certain
circumstances, requires sources to submit documentation of completion
of protected resources screening procedures (see 40 CFR 49.104). The
existing National O&NG FIP currently requires, in part, that the
screening procedures documentation be submitted (and the EPA's
confirmation of satisfactory completion of the protected resources
screening procedures be received) before the Part 1 Form may be
submitted (see 40 CFR 49.104(a)(2)). On July 15, 2019, the EPA proposed
to amend the National O&NG FIP to allow owners or operators of true
minor sources to concurrently submit to the EPA Regional Office the
Part 1 Form and the screening procedures documentation (see 84 FR
33715). The EPA did not propose to change the substantive requirements
for either the Part 1 Form or screening procedures documentation or the
requirement for EPA review of the screening procedures documentation.
In this final rule, the EPA is moving forward with the proposed
amendment without significant revision. The appropriate EPA Regional
Office will continue to assess whether the screening procedures have
been satisfactorily completed before construction or modification of
the proposed new and/or modified minor NSR source. This final rule also
expressly clarifies that, even though the Part 1 Form may be submitted
with the screening procedures documentation, construction may not begin
until at least 30 days has passed from the date the Part 1 Registration
Form was submitted, and the EPA Regional Office has provided written
notification of satisfactory completion of the screening procedures
documentation.

    \1\ 40 CFR 49.151-49.165.
    \2\ 40 CFR 49.101-49.105.
---------------------------------------------------------------------------

    The EPA also proposed other minor changes, including the following:
Clarification that the EPA, under the National O&NG FIP, may provide
written notification relating to its evaluation of the screening
procedures documentation not just by mail, but also by email; and
clarification that the Federal Minor NSR Program in Indian Country only
requires that the Part 1 Form be submitted at least 30 days before
consruction begins, not exactly 30 days before construction begins. The
EPA also proposed correcting a typographical error in a citation in the
National O&NG FIP; changing certain references in the National O&NG FIP
from ``Reviewing Authority'' to ``EPA Regional Office;'' and making
minor edits, in the Federal Minor NSR Program in Indian Country, to
enhance clarity and readability of a provision relating to the Part 2
Registration Form. The EPA received no adverse comments concerning
these minor, clarifying or correcting changes and, in this final rule,
the EPA is finalizing those changes, substantially as proposed. The EPA
does not anticipate the final rule changes will result in any increase
in environmental impact(s) or cost increase(s) for the tribes,
reviewing authorities or the regulated community.

II. Response to Comments

    A total of 20 comments \3\ were received on the proposed rule, two-
thirds (13) were generally supportive with some requests for
clarification. We received only one adverse comment expressing concern
that the EPA's proposed streamlining would reduce the time and
attention provided for the EPA review process. Some commenters
submitted concerns that were outside the scope of this rulemaking.
---------------------------------------------------------------------------

    \3\ Some comments are summarized and some brief responses are
provided, here, but for more complete responses to comments see the
Responses to Comments (RTC) in the docket for this rule. Refer to
the RTC for more information about the identity of the commenters
and comment summaries and response(s) not included in this
discussion. A total of 23 comments were received with 3 comments not
related to the current rulemaking; therefore 20 comments were
received related to this rulemaking.
---------------------------------------------------------------------------

    Comment: Nine commenters supported the rule as proposed noting that
streamlining the process for submitting the Part 1 Form and the
protected resources screening procedures documentation results in an
improvement by reducing unnecessary administrative delays, with no loss
of the EPA oversight in evaluating protected resources or of
environmental protection.
    Response: We agree with the commenters that concurrent submission
of the Part 1 Form and documentation of protected resources screening
procedures may streamline the process for sources subject to the
National O&NG FIP. In addition, there have been no changes to the
environmental protections of the rule and, under the revised provisions
that allow concurrent submission, the EPA still must review and approve
the screening procedures documentation before construction or
modification can begin, all of which ensures that threatened or
endangered species, historic properties, and the environment will
continue to be protected as under the existing rule.
    Comment: One commenter expressed concern about EPA's consultation
and coordination with Indian Tribal Governments as per EPA's Policy on
Consultation and Coordination with the Indian Tribes.\4\ The commenter
asserted that when the EPA Regional Office reviews the protected
resources screening documentation (whether generated by the owner/
operator or by another agency), as well as when the owner/operator
submits the Part 1 Form, the EPA Regional Office must consult and
coordinate with the affected Indian Tribe(s) whose resources may be
impacted by the source's operations. The commenter further recommended
that the EPA Regional Office notify the affected Indian Tribe(s)
immediately upon the EPA's receipt of the Part 1 Form or the screening
procedures documentation, noting that, because consultation and
coordination potentially can take significant time, the earlier the
notification, the better and that the affected Indian Tribe(s) have
governmental programs with substantial expertise regarding screening
documentation review and adequacy, such as a Historic Preservation
Officer and Departments of Cultural Resources, Fisheries, Wildlife,
Water, Air Quality, and Forestry. The commenter also stated that the
relevant EPA Regional Office must consult and coordinate with the
affected Indian Tribe(s) regarding the EPA Regional Office's review and
determination of adequacy of the protected resources screening
documentation.
---------------------------------------------------------------------------

    \4\ https://www.epa.gov/tribal/epa-policy-consultation-and-coordination-indian-tribes.
---------------------------------------------------------------------------

    Response: The EPA proposed no changes to the EPA's rules, policies,
or practices concerning Tribal consultation or coordination, including
in connection with the National O&NG FIP. The issues raised by the
commenter were not the subject of the proposed amendments to the
National O&NG FIP and they are outside the scope of this rulemaking and
will not be addressed here. However, we note that the existing
regulations at 40 CFR 49.104(a)(1) and (2) require that sources submit
screening procedures documentation to the relevant tribe as well as to
the EPA Regional Office, and the proposed amendments do not change
these requirements.
    Comment: One commenter opposed the proposed rule asserting that it
removes critical protections from oil and gas emissions and that the
EPA has not met its obligations to protect public health and welfare
and has not fulfilled its trust responsibilities to Indian tribes. The
commenter further stated that the EPA does not have an understanding of
the impacts of oil and gas development on native communities in Indian

country, noting the lack of air monitors for PM2.5,
PM10, and ozone within the tribal boundaries of the Ft.
Berthold Reservation. The commenter also said that increasing the pace
of review for oil and gas minor sources is not the answer to an
increase in development, and expressed significant concerns that the
proposal could lead to less stringent enforcement and implementation of
the Endangered Species Act (ESA), less protection of threatened or
endangered species, and disregard for protected cultural resources such
as historic properties. Further, the commenter asserted that the
proposed changes to the FIP would result in tying approval of the
protected resources screening procedures documentation to approval of
the Part 1 Form, reducing the time and attention provided to the review
of true minor source applications. The commenter also stated that any
automatic approval after a certain time period is not adequate
consideration of the threatened or endangered species of this land or
the cultural heritage and artifacts of native people. The commenter
commented that the proposal supported faster review of oil and gas
minor sources, which is unnecessary and part of a dangerous trend from
this Administration in removing critical protections from oil and gas
emissions, endangering the lives of native people living on
reservations.
    Response: In general, the EPA appreciates the commenter's concerns
about air quality. The EPA does not agree that the limited amendments
proposed to the National O&NG FIP will have a significant adverse
effect, if any, on air quality. Although the EPA maintains that there
may be some administrative streamlining advantages associated with the
proposed amendments, the EPA does not agree that the amendments will
substantially increase the rate of oil and natural gas development or
production. The proposed amendments also do not reduce or remove
existing air quality protections associated with the National O&NG FIP.
    As to the comments relating to minor source applications and the
EPA's review of such applications, sources covered by the National O&NG
FIP ordinarily are not required to submit site-specific permit
applications, but are required to register and comply with various
stated requirements and emissions standards. There is no application,
as such, for the EPA to review and the limited amendments here make no
change to this basic framework. With respect to the ESA/National
Historic Preservation Act (NHPA) screening procedures, the National
O&NG FIP continues to require review of the adequacy of the screening
procedures documentation. Both in the prior National O&NG FIP, and the
FIP as amended by this action, construction may not begin until the EPA
provides written notification of adequate completion of the screening
procedures.

III. Environmental Justice Considerations

    This action revises existing rules to streamline the administrative
process for sources covered by the National O&NG FIP by allowing the
the Part 1 Form to be submitted to the EPA at the same time as the
screening procedures documentation. It does not remove any of the prior
rules' environmental or procedural protections. The EPA believes that
this final action will not have potential disproportionately high and
adverse human health or environmental effects on minority, low-income,
or indigenous populations.

IV. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review

    This action is not a significant regulatory action and was,
therefore, not submitted to the Office of Management and Budget (OMB)
for review.

B. Executive Order 13771: Reducing Regulations and Controlling
Regulatory Costs

    This action is expected to be an Executive Order 13771 deregulatory
action. This rule is expected to provide meaningful burden reduction by
potentially reducing the waiting time before certain true minor new and
modified oil and natural gas sources can begin construction.

C. Paperwork Reduction Act (PRA)

    This action does not impose any new information collection burden
under the PRA. OMB has previously approved the information collection
activities contained in the Federal Minor NSR Program in Indian country
rule and has assigned OMB control number 2060-0003.\5\ The National
O&NG FIP, which this action amends, provides a mechanism for
authorizing construction or modification of true minor sources in the
oil and natural gas production and natural gas processing segments of
the oil and natural gas sector in areas covered by the Federal Minor
NSR Program in Indian country to satisfy the requirements of that rule
other than by obtaining a site-specific minor source permit. Because it
substitutes for a site-specific permit, which would contain information
collection activities covered by the Information Collection Request for
Federal Minor NSR Program in Indian country rule issued in July 2011,
neither the amendments nor the National O&NG FIP impose any new
obligations or new enforceable duties on any state, local, or tribal
government or the private sector.
---------------------------------------------------------------------------

    \5\ Since the Federal Minor NSR Program in Indian country rule
was promulgated, the Information Collection Request (ICR) has been
renewed and approved by OMB twice. The most recent approval extended
the ICR until October 31, 2020. The ICR covers the activities of the
National O&NG FIP. For more information, go to: https://www.reginfo.gov/public/do/PRAViewICR?ref_nbr=201702-2060-005.
---------------------------------------------------------------------------

D. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic
impact on a substantial number of small entities under the RFA. In
making this determination, the impact of concern is any significant
adverse economic impact on small entities. An agency may certify that a
rule will not have a significant economic impact on a substantial
number of small entities if the rule relieves regulatory burden, has no
net burden or otherwise has a positive economic effect on the small
entities subject to the rule. This action merely modifies the timing to
allow required documentation to be submitted at an earlier point in the
regulatory process. The EPA analyzed the impact on small entities of
streamlined permitting resulting from this rule and determined that it
would not have a significant economic impact on a substantial number of
small entities. We have therefore concluded that this action will have
no net regulatory burden for all directly regulated small entities.

E. Unfunded Mandates Reform Act (UMRA)

    This action does not contain any unfunded mandates, as described in
UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect
small governments. The action imposes no enforceable duty on any state,
local, or tribal government or the private sector. In material part, it
simply modifies the permissible time-frame for submission of otherwise
required forms to streamline the National O&NG FIP and Federal Minor
NSR Program in Indian country.

F. Executive Order 13132: Federalism

    This action does not have federalism implications. It would not
have substantial direct effects on the states, on the relationship
between the

National Government and the states, or on the distribution of power and
responsibilities among the various levels of government.

G. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments

    This action may have tribal implications. However, it will neither
impose substantial direct compliance costs on federally recognized
tribal governments, nor preempt tribal law. Consistent with the EPA
Policy on Consultation and Coordination with Indian Tribes (May 4,
2011),\6\ the EPA offered consultation on the proposed action. The EPA
conducted outreach on issues related to the Federal Minor NSR Program
in Indian country and the National O&NG FIP via ongoing monthly
meetings with tribal environmental professionals.\7\ We did not receive
a formal tribal consultation request for this rulemaking.
---------------------------------------------------------------------------

    \6\ For more information, go to: https://www.epa.gov/tribal/epa-policy-consultation-and-coordination-indian-tribes.
    \7\ These monthly meetings are general in nature, dealing with
many air-related topics, and are not specific to this final action.
---------------------------------------------------------------------------

H. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks

    This action is not subject to Executive Order 13045 because it is
not economically significant as defined in Executive Order 12866, and
because the EPA does not believe the environmental health or safety
risks addressed by this action present a disproportionate risk to
children.

I. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution or Use

    This action is not subject to Executive Order 13211, because it is
not a significant regulatory action under Executive Order 12866.

J. National Technology Transfer and Advancement Act (NTTAA)

    This action does not involve technical standards.

K. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations

    The EPA believes this action does not have potential
disproportionately high and adverse human health or environmental
effects on minority, low-income or indigenous populations. Through this
amendment, we seek to further streamline the process for true minor
sources in the oil and natural gas sector in areas covered by the
Federal Minor NSR Program in Indian country. This action does not
remove any of the prior rules' environmental or procedural protections.

L. Congressional Review Act (CRA)

    This rule is exempt from the CRA because it is a rule of agency
organization, procedure or practice that does not substantially affect
the rights or obligations of non-agency parties.

M. Judicial Review

    Under section 307(b)(1) of the CAA, petitions for review of this
final action must be filed in the U.S. Court of Appeals for the
appropriate circuit within 60 days from the date this final action is
published in the Federal Register.

    Authority: 42 U.S.C. 7401, et seq.

Subpart C--General Federal Implementation Plan Provisions

0
2. In Sec.  49.104, revise paragraphs (a) introductory text, (a)(2)
introductory text, (a)(2)(i) introductory text, (a)(2)(i)(B), and
(a)(2)(ii) to read as follows:

Sec.  49.104  Requirements regarding threatened or endangered species
and historic properties.

    (a) What are sources required to do to address threatened or
endangered species and historic properties? An owner/operator subject
to the requirements contained in Sec. Sec.  49.101 through 49.105 to
satisfy its obligation under Sec.  49.151(c)(1)(iii)(B) to obtain a
minor NSR permit shall meet either paragraph (a)(1) or (2) of this
section, as appropriate.
* * * * *
    (2) Screening procedures completed by the owner/operator. The
owner/operator shall submit to the EPA Regional Office (and to the
relevant tribe for the area where the source is located/locating)
documentation demonstrating that it has completed the required
screening procedures specified for consideration of threatened or
endangered species and historic properties and receive written
confirmation from the EPA stating that the owner/operator has
satisfactorily completed these procedures. The completed screening
procedures documentation may be submitted together with the source's
required Sec.  49.160(c)(1)(iv) Part 1 Registration Form. (The
procedures are contained in the following document: ``Procedures to
Address Threatened and Endangered Species and Historic Properties for
the Federal Implementation Plan for Managing Air Emissions from True
Minor Sources in Indian Country in the Oil and Natural Gas Production
and Natural Gas Processing Segments of the Oil and Natural Gas
Sector,'' https://www.epa.gov/tribal-air/tribal-minor-new-source-review). Review of your submittal will be conducted by the EPA Regional
Office in accordance with the procedure in paragraphs (a)(2)(i) and
(ii) of this section:
    (i) Within 30 days of receipt of your documentation, by written
notification to you, the EPA Regional Office must provide one of the
following determinations:
* * * * *
    (B) The documentation is not adequate, and additional information
is needed. If the initial submittal is deficient, the EPA Regional
Office will note any such deficiencies and may offer further direction
on completing the screening procedures. Once you have addressed the
noted deficiencies, you must resubmit your revised screening procedure
documentation for review. An additional 15-day review notification
period will be used for the EPA Regional Office to determine whether
the listed species and/or historic property screening procedures have
been satisfied. If the EPA Regional Office makes such a determination,
it will send you written notification stating that conclusion.
    (ii) You must obtain written notification from the EPA Regional
Office indicating that the source has adequately completed the
screening procedures. The EPA Regional Office may send written
notification by mail, email, or any other written means of
notification. You may not begin

construction under this FIP until the following two conditions are met:
    (A) At least 30 days has passed from the date the Part 1
Registration Form was submitted; and
    (B) The EPA Regional Office has provided this notification.
* * * * *

3. In Sec.  49.160, revise paragraph (c)(1)(iv) to read as follows:

Sec.  49.160  Registration program for minor sources in Indian country.

* * * * *
    (c) * * *
    (1) * * *
    (iv) Minor sources complying with Sec. Sec.  49.101 through 49.105
for the oil and natural gas production and natural gas processing
segments of the oil and natural gas sector, as defined in Sec.  49.102,
must submit, at least 30 days prior to beginning construction, the Part
1 Registration Form containing the information in paragraph (c)(2) of
this section. The Part 2 Registration Form, including emissions
information, must be submitted within 60 days after the startup of
production as defined in Sec.  49.152(d). The source must determine the
potential for emissions within 30 days after startup of production.
    The combination of the Part 1 and Part 2 Registration Forms
submittals satisfies the requirements in paragraph (c)(2) of this
section. These forms are submitted to the EPA instead of the
application form required in paragraph (c)(1)(iii) of this section. The
forms are available at: https://www.epa.gov/tribal-air/tribal-minor-new-source-review or from the EPA Regional Offices.
