1. CAS Numbers. We updated CAS numbers for the following chemicals: Coke Oven Emissions (E649830) and Polybrominatedbiphenyls (36355-01-8). Numbers that begin with "E" are EPA identification numbers and are used due to the lack of a CAS number.Note - CAS numbers in CLARC and EPA's Regional Screening Levels (RSL) table are consistent. The information on alternative CASnumbers on the CLARC Data Tables webpage has been updated to reflect this.

2. Soil Cleanup Levels to Protect Groundwater - April 2019 CLARC Guidance. We updated this CLARC guidance to address editorialand clarity issues.

3. Soil Protective of Groundwater for Saturated Soil Calculations. We made updates to include soil protective of groundwaterlevels for the saturated zone for organics that have a distribution coefficient (Kd) value, but no Henry's Law constant in CLARC. AHenry’s Law constant is not needed to calculate soil protective of groundwater cleanup levels for saturated zone soil since thedefault air-filled soil porosity is assumed to be zero. This change effects the following chemicals: aroclors 1254, 1260, and 1016;total PCBs; 2,3,4,6-tetrachlorophenol; pentachlorobenzene; and paraquat dichloride.

4. Chemical-specific note for pH. This note was updated to reflect that a Soil Organic Carbon-Water Partitioning Coefficient (Koc)value reflective of a pH of 6.8 was used in the soil protective of groundwater calculations for the listed ionizing organic chemicals.

5. Chemical-specific values. A summary of updates is provided below.

polychlorinated biphenyls (PCBs): Calculated a Kd value using the defaults in MTCA Equation 747-2. A soil protective of groundwater level for the saturated zone was calculated.Aroclor 1254: Added a Koc value from EPA's 1994 Soil Screening Guidance.

6. Eliminated Chemicals. The 40 chemicals/parameters in the table below were eliminated from CLARC due to the lack of toxicity data, cleanup levels, and levels based on state and federal requirements.

7. Uranium Soluble Salts.

In 2020, Ecology completed a consultation process with EPA and the Washington State Department of Health (DOH) on using the ATSDR oral minimal risk level (MRL) instead of the current IRIS oral RfD for soluble uranium. Both EPA and DOH concurred with Ecology's decision to use the ATSDR oral MRL over the IRIS oral RfD value. Please see Ecology's supplemental CLARC guidance on soluble uranium using the CLARC link below.

In 2002, EPA’s NCEA, which manages IRIS, conducted a literature review for uranium and identified new relevant toxicological studies that may yield a change in the uranium oral reference dose (RfD). The existing uranium oral RfD in IRIS is based on a single-dose response study from 1949. In 2013, ATSDR conducted a comprehensive review and evaluation of available toxicity studies and derived an intermediate minimum risk level (MRL; see ATSDR link below). The MRL is a dose that is likely to be without an appreciable risk of adverse noncancer effects over a specified duration of exposure. ATSDR concluded that continued exposure beyond an intermediate duration is not likely to induce more severe effects, and may be adequately protective of chronic exposures. The MRL derived by ATSDR for soluble uranium is 15 times lower (this yields lower cleanup levels) than the oral RfD published in IRIS.

In a memo dated December 21, 2016 (see EPA link below), the EPA Superfund Program recommended that the ATSDR MRL be used in place of the RfD in IRIS without any further adjustment to assess chronic oral exposures. Ecology agrees with EPA that ATSDR’s MRL was derived using better and more relevant data than the study that formed the basis for the RfD in IRIS, and is scientifically defensible. The techniques used by ATSDR to derive its RfD are consistent with those used by EPA’s IRIS program and those recommended in MTCA (WAC 173-340-708(7)(f)).

IRIS is undertaking a reassessment of the noncancer, nonradiological health effects of uranium via oral exposure. Uranium was included on the December 2015 IRIS Program multiyear agenda as a chemical having high priority for assessment development. Ecology will re-evaluate using the ATSDR oral MRL for uranium if and when IRIS is updated to provide a new noncancer oral RfD for soluble uranium.

What's New & Other NotesCLARC Table - August 2020

Updated toxicity values are highlighted in blue (no pattern) in the table.

8. Toxicity Value Updates. Toxicity values in CLARC for the following hazardous substances have been changed based on a review of EPA's May 2020 Regional Screening Level Table. Updated toxicity values are highlighted in blue in the table. Cells highlighted in blue with no value means that the old value was removed.

1. Inhalation RfC/RfDi: Added for antimony.2. Inhalation IUR/CPFi: Removed for chlorothalonil and 2-methoxy-5-nitroaniline; updated for direct black 38, direct blue 6, and direct brown 95.3. Oral RfDo: Updated for uranium, soluble salts.4. Oral CPFo: Added for nickel refinery dust; updated for chlorothalonil and direct black 38.

Other Notes1. Hazardous Substances with Chemical-Specific Considerations. For some hazardous substances, potential default cleanup levels may require special calculations or consideration of site-specific factors. Examples include benzo[a]pyrene/cPAHs, and hardness-dependent metals criteria for applicable state and federal fresh surface water laws. Many of these hazardous substances are listed in the CLARC tables with CAPITAL LETTERS and gray-shaded cells. A column (Links to Important Notes) is included in the table which contains links to relevant information. Many of the links go to a worksheet in this spreadsheet labeled "Notes - Chemical-Specific," while other links go to individual PDF documents.

2. Henry Constants for Soil to Groundwater Cleanup Level Calculations. For default calculation of soil cleanup levels to protect groundwater, Henry Constants at 13 degrees Celsius should be used. For total xylenes, the 13 degree Celsius Henry Constant in CLARC was calculated as the mean of the individual values of the 3 isomers.

Sources of cancer toxicity data that include a mutagenic mode of action are highlighted in orange/dotted pattern (see I-M)

3. Sources of toxicity values. The source of each toxicity value is listed in the Excel and PDF files using the following abbreviations:

I = IRIS (Integrated Risk Information System) database from the Environmental Protection Agency (EPA) I-M = Toxicity source is IRIS and the chemical is evaluated based on a mutagenic mode of action for early life exposure (highlighted in orange/dotted pattern with bold text) P = PPRTV = Provisional Peer-Reviewed Toxicity Values from EPA's Superfund Health Risk Technical Support Center (STSC) (STSC is within EPA's Office of Research and Development's (ORD's) Center for Public Health and Environmental Assessment, formerly known as the National Center for Environmental Assessment [NCEA]). X = PPRTV Screening Level (does not meet all of requirements for a standard PPRTV value) H = HEAST = Health Effects Assessment Summary Table from EPA C = Cal EPA = California Environmental Protection Agency A = ATSDR = Agency for Toxic Substances and Disease Registry O = EPA Office of Pesticide Programs S = Other EPA sources

Note: The oral cancer slope factor for chromium (VI), ethylbenzene, and naphthalene from Cal EPA, and the inhalation cancer potency factor for ethylbenzene from Cal EPA, have not been included in CLARC pending further evaluation.

Notes - Noncancer Effects TableSource: A = ATSDR; I = EPA IRIS; O = EPA Office of Pesticide Programs

MTCA human health cleanup levels for individual noncarcinogens are based on achieving a hazard quotient (HQ) of 1. An HQ is derived by comparing a human health receptors (e.g., a child or adult resident) estimated daily dose of a hazardous substance to the reference dose. The reference dose is considered an estimate of a daily oral exposure level that is likely to be without an appreciable risk of harmful effects during a lifetime. If the average daily dose is higher than the reference dose, then there is a potential for a noncancer health effect to occur and the hazard quotient is greater than 1. When there are multiple noncarcinogenic chemicals of concern at a site, the HQs for each are summed up to derive a hazard index (HI). The HI is an expression of the additivity of noncarcinogenic health effects. The principle of additivity assumes that similar organ systems and health endpoints will be affected by the chemicals of concern. As such, and consistent with EPA superfund risk assessment guidance, MTCA allows noncancer hazard quotients from multiple chemicals to be apportioned by similar type of toxic response when evaluating compliance with the noncancer target HI of 1.

The information provided in the CLARC noncancer effects table, which was compiled based on information from EPA’s Integrated Risk Information System (IRIS) database, can be used to calculate hazard indices for groups of chemicals with similar types of noncancer effects. Groupings can be made by major noncancer effect categories such as neurotoxicity, developmental toxicity, reproductive toxicity, immunotoxicity, and adverse effects by target organ. This information is presented in the table by exposure route (i.e., ingestion or inhalation) for those chemicals with noncarcinogenic toxicity data available in EPA’s IRIS database.

Note that there is a not a table showing carcinogenic tumor types. For cancer causing chemicals (a.k.a., carcinogens), the total cancer risk is derived by summing the cancer risk for all chemicals of concern. This approach is in accordance with MTCA and is consistent with EPA guidelines in which risks associated with carcinogens are considered additive with the same toxicological endpoint (i.e., cancer).

CLARC Chemical-Specific Considerations - August 2020Ammonia

The calculation of WAC 173-201A fresh water ammonia criteria for protection of aquatic species depends on the water quality characteristics (temperature and pH), fish life-stage, and the chemical form/species of ammonia (e.g., ionized or non-ionized). For federal CWA 304A protection of aquatic species, the ammonia Freshwater criteria vary depending on pH, temperature and life-stage. The CWA 304A ammonia Saltwater criteria vary depending on pH and temperature.

Asbestos

The unit of measurement for asbestos in water is fibers/liter (and not the usual milligrams/liter or micrograms/liter). CLARC lists the federal and Washington State Maximum Contaminant Levels for asbestos (7 million fibers per liter), but does not provide pre-calculated Method B or C formula values which would depend on fiber type and content.

For inhaled asbestos, the number listed for the inhalation unit risk is in fibers/milliliter. An inhalation cancer potency factor could not be calculated.

Benzo[a]pyrene and Carcinogenic PAHs

In January, 2017, the U.S. Environmental Protection Agency (EPA) published several changes to the toxicity values for benzo[a]pyrene (BaP) in its Integrated Risk Information System (IRIS) database. EPA also determined that benzo[a]pyrene has a mutagenic mode of action and therefore recommended the use of ADAFs (age-dependent adjustment factors) to address increased childhood sensitivity (compared to adults) to its carcinogenic (cancer-causing) effects. These changes affect some Model Toxics Control Act Method B and Method C cleanup levels for BaP and for carcinogenic polycyclic aromatic hydrocarbons (cPAHs). Updated toxicity values and the approach for calculating cleanup levels for BaP and cPAHs are presented in a January 2020 Ecology memorandum (see link below - PAH/BaP January 2020 Memo). Application of Toxicity Equivalence Factors (TEFs) in calculating cleanup levels for cPAH mixtures is described in Implementation Memo #10 (see link below - cPAH TEF Implementation #10).

CLARC Chemical-Specific Considerations - August 2020Cadmium - Soil and Water

EPA’s IRIS database lists two oral noncancer reference doses for cadmium, one for cadmium in water (0.0005 mg/kg-day) and one for cadmium in food (0.001 mg/kg-day). As explained in EPA’s User’s Guide for the Regional Screening Levels Tables (see link below for EPA RSL Table), the oral reference dose for cadmium in food should be used for the assessment of noncancer effects to soil and biota. When using the MTCA Equations to calculate soil, groundwater, and surface water cleanup levels, the more protective oral reference dose (0.0005 mg/kg-d for “water”) is used for potable groundwater and surface water, while the less protective one (0.001 for “food”) is used for soil and nonpotable surface water (where the calculated cleanup level is based on ingestion of fish and shellfish).

Cadmium - Applicable Federal and State Laws for Fresh Surface Water

For cadmium, federal and state fresh surface water criteria for the protection of aquatic life vary depending on hardness of the water at the site (see link below)

Chromium

CLARC does not provide pre-calculated standard Method B or C formula values for total chromium. CLARC does provide pre-calculated standard Method B and C formula values for chromium III and chromium VI. Assessors should test for total chromium first and then test for chromium VI only if the concentration for total chromium exceeds the cleanup level for chromium VI.

If chromium VI is present at the site, then the concentration of chromium III is determined by subtracting the chromium VI concentration from the total chromium concentration. If chromium VI is NOT present at the site, then the site assessor may assume that the measured concentration of total chromium is the concentration of chromium III.

If there is documented evidence that chromium VI was never used at the site, then the site assessor does not need to test for chromium VI and may assume that the measured concentration of total chromium is the concentration of chromium III.

For groundwater, the total chromium federal and Washington State Maximum Contaminant Level is 100 µg/L, and CLARC contains the value from the Method A Groundwater Table (Table 720-1) of 50 µg/L. The Method A number assumes that a portion of the chromium is hexavalent; if all of the chromium is trivalent, then the Method A number is 100 µg/L.

Chromium - Applicable Federal and State Laws for Fresh Surface Water

For chromium, federal and state fresh surface water criteria for the protection of aquatic life vary depending on hardness of the water at the site (see link below).

CLARC Chemical-Specific Considerations - August 2020Cyanide

In broad terms, analytical techniques for cyanide can quantify either “total” cyanide or “free” cyanide. The oral reference dose for cyanide that is listed in CLARC, and the cleanup levels calculated with the MTCA Equations, are based on free cyanide, meaning that results from analyses for free cyanide are acceptable for samples. A total cyanide measurement is also acceptable, but the measured concentration of total cyanide in a sample may be higher than the concentration quantified with a free cyanide analysis, potentially leading to unnecessary cleanup.

CLARC also lists several individual cyanide compounds with reference doses from IRIS:

Fluoride

Different agencies, including Ecology, have used several CAS numbers to identify fluoride. The CLARC Tables will now use a single name (“fluoride”) and a single CAS number (16984-48-8) to evaluate fluoride contamination in water, soil, and air. ChemIDplus lists this CAS number as “Fluoride,” “F-,” or “inorganic salts of hydrofluoric acid, HF, in which the fluorine atom is in the -1 oxidation state.”

The following CAS numbers are assumed to be equivalent for the purpose of screening water, soil, and air for fluoride (unless analyzing specifically for fluorine gas, CAS 7782-41-4):

• 7664-39-3, listed in ChemIDplus as hydrofluoric acid or hydrogen fluoride. This is the CAS number associated with the California EPA Reference Exposure Levels for hydrogen fluoride. Cal EPA also has a listing for “Fluorides (other than Hydrogen Fluoride)” without a CAS number. CLARC does not include the Cal EPA oral REL because the oral reference dose for soluble fluoride that is listed in IRIS is used instead. The Cal EPA inhalation REL for “Fluorides (other than Hydrogen Fluoride)” is listed in CLARC and has been associated with CAS 16984-48-8.

• 7681-49-4, listed in ChemIDplus as sodium fluoride. This is the CAS number associated with the U.S. EPA Maximum Contaminant Level for fluoride.

• 7782-41-4, listed in ChemIDplus as fluorine gas. This is the CAS number associated the listing in the U.S. EPA IRIS database (listed as Fluorine; soluble fluoride). Note that the IRIS reference dose is based on studies of fluoride in drinking water and not fluorine gas.

Gross alpha particle activity

The unit of measure for the Method A and Maximum Contaminant Level value of 15 is picocuries/liter (not micrograms/liter).

Gross beta particle activity

The unit of measure for the Method A and Maximum Contaminant Level value of 4 is millirem/year (not micrograms/liter).

CLARC Chemical-Specific Considerations - August 2020

Hardness-dependent Fresh Surface Water Criteria to Protect Aquatic Life

For the following metals, fresh surface water criteria for the protection of aquatic life are not a single number, but change based on hardness of the water at the site:

• Cadmium• Chromium III• Copper• Lead• Nickel• Silver• Zinc

To calculate the appropriate criteria for Ecology’s 201A, apply site-specific hardness to the formulas provided in WAC 173-201A-240 (see link below).

For EPA’s Recommended Water Quality Criteria, apply site-specific hardness to the formulas provided in EPA's National Recommended Water Quality Criteria Table (CWA 304; see link below). Note that for its copper criteria, EPA recommends using the Biotic Ligand Model (see link below).

Prior to 2018, fresh water 201A criteria listed in CLARC were based on a hardness of 25 mg/L and those for 304A were based on a hardness of 100 mg/L. As of this update, both sets of criteria are based on a hardness of 100 mg/L.

Lead

CLARC does not provide pre-calculated standard Method B or C formula values for lead. Values for lead cannot be calculated using the equations provided in the regulation. Assessors should consult with the Department of Ecology regarding the use of EPA’s Integrated Exposure Uptake Biokinetic (IEUBK) model to calculate soil cleanup levels (see link below).

Lead - Applicable Federal and State Laws for Fresh Surface Water

For lead, federal and state fresh surface water criteria for the protection of aquatic life vary depending on hardness of the water at the site (see link below).

Manganese

The oral reference dose used in the soil and water Method B and C cleanup level calculations was obtained from the U.S. Environmental Protection Agency’s Integrated Risk Information System (IRIS) and is based on manganese intake from food. EPA recommends modifying (dividing) the reference dose by a factor of 3 when assessing manganese exposure to water or soil. This generates a modified oral reference dose of 0.0467 mg/kg-day to be applied to non-food sources such as soil and water. The reasons for this adjustment are described in EPA’s IRIS summary.

CLARC Chemical-Specific Considerations - August 2020

Methyl mercury

The unit of measure for the methyl mercury surface water cleanup levels for human health protection is milligrams per kilogram of fish tissue, not micrograms per liter of water.

WAC 173-201A Table 240 does not specifically list a protective concentration for methylmercury. However, the notes for mercury aquatic life chronic criteria (fresh and marine water) indicate that if the four-day average chronic surface water concentration is exceeded more than once in a three-year period, the edible portion of the consumed species should be analyzed and shall not be allowed to exceed 1.0 mg/kg of methylmercury (see link below)

pH-dependent calculations

For the following chemicals, the cleanup levels for soil to protect groundwater vary depending on the pH of the soil.Soil Organic Carbon-Water Partitioning Coefficient (Koc) values based on a pH of 6.8 were used to calculate cleanup levels for soil to protect groundwater for the chemicals below.

Benzoic acidChlorophenol;2-Dichlorophenol;2,4-Dinitrophenol;2,4-PentachlorophenolTetrachlorophenol;2,3,4,6-Trichlorophenol;2,4,5-Trichlorophenol;2,4,6-

Use the link below for information on determining the appropriate soil cleanup level to protect groundwater for these chemicals.

Washington State (WAC 201A) freshwater aquatic life criteria for pentachlorophenol are pH dependent. The values presented in CLARC correspond to a pH of 7.8 which is the same default pH used by EPA in their Ambient Water Quality Criteria. The formulas provided in WAC 173-201A-240 should be used to derive freshwater acute and chronic criteria for pentachlorophenol based on site-specific pH (see link below).

Radium 226

The unit of measure for the Method A number is picocuries/liter (not micrograms/liter).

Radium 226 and 228

The unit of measure for the Method A and Maximum Contaminant Level is picocuries/liter (not micrograms/liter).

The unit of measure for the inhalation reference concentration is fibers/m3 (not mg/m3). An inhalation reference dose could not be calculuated.

Total Trihalomethanes (TTHM) - Maximum Contaminant Levels

The individual trihalomethanes (bromodichloromethane, bromoform, chloroform, dibromochloromethane, chloroform) all have the state and federal MCL of 80 micrograms/liter listed in the table. However, 80 micrograms/liter is the MCL for Total Trihalomethanes (mixtures containing more than one of these chemicals). If the mixture contains only one of these chemicals, then the MCL of 80 micrograms/liter would apply to that chemical.

Listed Maximum Contaminant Level for Disinfectants

The chemical is a water additive used to control microbes. The listed MCL is a Maximum Residual Disinfectant Level (MRDL). The MRDL is the highest level of a disinfectant allowed in drinking water (see link below).

pH Units

pH criteria are expressed in terms of pH units, not micrograms per liter. EPA's freshwater human health pH criteria range (pH of 5 to 9) is based on protection of domestic water supplies (see link below to EPA's 1986 Gold Book). A range of pH from 5 to 9 provides a water treatable by typical (coagulation, sedimentation, filtration, and chlorination) treatment plant processes.
