In addition, EPA is making these materials publicly available to offer information to criteria developers outside of the EPA, including states and authorized Tribes, that could consider conducting systematic review of ecological effects data following OW's process described in this SOP. This document is only intended to be informative and descriptive and does not provide or make recommendations about what other entities should do to conduct systematic review in the development of AWQC. This document supports the screening, review, documentation, and use of data from various sources and can assist criteria developers in determining if and in what manner (e.g., quantitatively or qualitatively) a study could be used in an effects assessment to support development of aquatic life criteria and other protective values (e.g., aquatic life benchmarks and screening values). The SOP is generally consistent with evaluation guidelines developed by the EPA Office of Chemical Safety and Pollution Prevention (OCSPP) (e.g., U.S. EPA 2011) to support a common approach to data evaluation for chemicals. 1.2 Background One of the objectives of the Clean Water Act (CWA) (33 U.S.C. Sections 125 l-1387is to protect and restore the biological, chemical, and physical integrity of waters in the United States. Pursuant to CWA Section 304(a), the EPA is required to publish, and from time to time thereafter revise, criteria for water quality to accurately reflect the latest scientific knowledge. AWQC are levels of individual pollutants, water quality characteristics, or descriptions of conditions of a water body that, if met, are expected to protect the aquatic community. AWQC for the protection of aquatic life and aquatic-dependent wildlife, developed under Section 304(a), reflect current scientific knowledge and are based on data and scientific determinations of the relationship between concentrations of a pollutant and its effects on aquatic life. The EPA's national recommended AWQC are not rules, nor do they automatically become part of a state's water quality standards. The EPA develops recommended AWQC based on the best available science, a scientific literature review, established procedures for risk assessment, EPA policy, and external scientific peer review and public input. States and authorized Tribes may adopt criteria that the EPA publishes under CWA Section 304(a), modify the CWA 304(a) criteria to reflect site-specific conditions, or adopt criteria based on other scientifically defensible methods (40 C.F.R. § 131.11(b)(1)). Under CWA Section 303 and the EPA's implementing regulations at 40 C.F.R. Part 131, the EPA must review and approve new or revised state water quality standards, including criteria. A state must adopt criteria that protect the designated use and are based on a sound scientific rationale (40 C.F.R. § - Page 3 of 178 - ------- 131.11(a)(1)). Since 1985, the EPA's AWQC for the protection of aquatic life have been derived based on methods outlined in the EPA's Guidelines for Deriving Numerical National Water Quality Criteria for the Protection of Aquatic Organisms and Their Uses (hereafter referred to as "GuidelinesUS EPA 1985). The Guidelines have provided consistency and transparency in the derivation methodology of AWQC for pollutants. The Guidelines include detailed direction on acceptability of toxicity test results and minimum data requirements (see Attachment A) to ensure the quality and sufficiency of data used in the derivation of nationally recommended AWQC. This SOP was developed by synthesizing the principles in the 1985 Guidelines and other EPA data quality guidance to transparently and consistently document the systematic review of data used in the development of AWQC. AWQC are based on an evaluation of available toxicological effects data for a pollutant for aquatic life and/or aquatic-dependent wildlife [taxa that depend on aquatic prey (e.g., fish and emergent aquatic insects) as their major food source]. Most ecological effects data for pollutants are obtained from the U.S. EPA ECOTOXicology Knowledgebase 1 (ECOTOX, Olker et al. 2022), maintained by the EPA's Office of Research and Development. Another important source of information used in the development of AWQC for pesticides is toxicity data acquired through U.S. EPA's Office of Pesticide Programs (OPP) (under the Federal Insecticide, Fungicide, and Rodenticide Act, 40 CFR Part 158). Applicable toxicity data from EPA researchers and sources external to the EPA, such as other federal agencies, academic researchers, and other international environmental regulatory authorities are also considered during the development of AWQC. 1.3 Organization of the Document This document is divided into the following three sections that describe a systematic review approach: • Screening the Open Literature: Discusses the general screening of papers and categorization of acceptability (i.e., applicable, non-applicable, and "others"). • Reviewing the Open Literature: Provides technical support for reviewing studies that pass the screening process to assess the quality of the study and determine its usability in AWQC development. • Documenting the Open Literature: Provides technical support for the efficient and consistent process for documenting reviews of the open literature and avoiding duplicative and possibly conflicting efforts associated with study reviews across reviewers. 1 ECOTOX is a publicly available database that curates the ecological effects of single chemicals to aquatic and terrestrial plants and animals. For more information on ECOTOX literature review and data curation processes, database documentation, controlled vocabularies, and guides for users, see the overview in Olker et al. 2022 and visit EPA's ECOTOX website at https://cfpub.epa.gov/ecotox/. - Page 4 of 178 - ------- The flowchart depicted in Figure 1 summarizes the Systematic Review Process for open literature studies.

ECOTOX = US EPA Ecotoxicology Database; AWQC = Ambient Water Quality Criteria: DER = Data Evaluation Record. - Page 5 of 178 - ------- 2 Screening the Open Literature The purpose of this section is to discuss the screening process applied to identify potentially useful open literature studies. OW uses ECOTOX as its primary search engine to obtain relevant acute and chronic toxicity information for AWQC development. ECOTOX is a source for locating single chemical toxicity data for aquatic life, terrestrial plants, and wildlife. ECOTOX was created and is maintained by the U.S. EPA's Office of Research and Development/Center for Computational Toxicology and Exposure's Great Lakes Toxicology and Ecology Division, and has well-established systematic review and data curation processes used for both Program offices and database chemical searches procedures. The screening process begins with a comprehensive chemical-specific literature search of the open literature conducted according to ECOTOX Standard Operating Procedures. The search terms in ECOTOX are comprised of chemical terms, synonyms, degradates, and verified Chemical Abstracts Service (CAS) numbers. For example, the literature search terms for Phosphoric acid, triphenyl ester are as follows: "Antioxidant TTP" OR "BRN1888236" OR "Celluflex TPP" OR "DHPF 005" OR "Disflamoll TP" OR "NSC 57868" OR "0,0,0-Triphenyl phosphate" OR "Phenyl phosphate" OR "Phoscon FR 903N" OR "Phosflex TPP" OR "Phosphoric acid, triphenyl ester" OR "Phosphoric acid, triphenyl ester radical ion(l+)" OR "Reofos TPP" OR "Sumilizer TPP" OR "Triphenolphosphate " OR "Triphenoxyphosphine oxide " OR "Triphenylphosphate " OR "Triphenylphosphat" OR "Triphenylphosphate" OR "UN3077" OR "UNII-YZE19Z66EA" OR "Wako TPP" OR "WSFR-TPPOnce the references are generated, they are tagged with exclusion keywords (see Figure 2 and Attachment C). After developing the literature search strategy, the ECOTOX literature review process includes conducting the searches, identifying potentially applicable studies based on title and abstract, acquiring potentially applicable studies, applying the ECOTOX applicability criteria (see Section 2.1), and abstracting the data, with respect to the acceptability of the study report for inclusion in the knowledgebase, into ECOTOX (see Figure 2). Studies that meet the applicability criteria are coded to reflect information on the chemical, species, habitat, test location, exposure route, control type, endpoint and effect. At each step, search terms and results, screening decisions, and respective tags are recorded and stored electronically in the ECOTOX Knowledgebase for both applicable and non-applicable studies. This process is documented in U.S. EPA (2023) and described in Olker et al. (2022). - Page 6 of 178 - ------- Figure 2. Overview of the literature searches, citation identification, and applicability criteria used by the ECOTOX Knowledgebase as described in U.S. EPA (2023). Although this section of this SOP focuses on the evaluation of toxicological studies obtained through ECOTOX, many of the approaches applied to the evaluation of these studies are also applicable to the evaluation of studies from other sources. All papers identified in the ECOTOX database search as having data that are potentially relevant to AWQC derivation are obtained and screened for data quality. When requesting the data pull from ECOTOX, OW obtains all applicable studies (with pdfs), as well as the non-applicable studies (with reason for exclusion), and the studies in the "other" category. To ensure data quality and verifiability, these studies should meet certain applicability criteria described to be considered for use in the development of AWQC. Studies are assigned to one of three categories based on the applicability evaluation: (1) Studies accepted by ECOTOX and OW (Section 2.1); (2) Studies accepted by ECOTOX but not by OW (Section 2.2); (3) Studies rejected by either ECOTOX or OW (Section 2.3); and (4) "Other" studies (Section 2.4). - Page 7 of 178 - ------- 2.1 Studies Accepted by ECOTOX and OW Traditionally, toxic effects of a chemical should be relevant to a whole organism (including aquatic animal, aquatic-dependent wildlife or aquatic plant species) to be considered for use in the development of AWQC. However, increasingly in vitro methods are used to assess toxicity for priority setting and screening assessments, and as quantitative linkages between these in vitro endpoints and apical endpoints of regulatory concern (survival, growth, and reproduction) are established, they may be considered for quantitative risk assessment. To be accepted by OW, regardless of whether the study is identified through the ECOTOX database or outside literature sources, papers should meet the following minimum criteria based on the ECOTOX applicability criteria: (1) The toxic effects are related to single chemical exposure (unless the study is being considered as part of a mixture effects assessment); (2) There is a biological effect on live, whole organisms or in vitro preparation including gene chips or omics data on adverse outcome pathways potentially of interest; (3) Chemical test concentrations are reported; (4) There is an explicit duration of exposure; (5) Toxicology information that is relevant to OW is reported for the chemical of concern; (6) The paper is published in the English language; (7) The paper is available as a full article (not an abstract); (8) The paper is publicly available; (9) The paper is the primary source of the data; (10) A calculated endpoint is reported or can be calculated using reported or available information; (11) Treatment(s) are compared to an acceptable control; (12) The location of the study (e.g., laboratory vs. field) is reported; and (13) The tested species is reported (with recognized nomenclature). Attachment B discusses the ECOTOX and OW applicability criteria in detail, as well as the criteria for studies that are rejected from the ECOTOX database and thus tagged as non- applicable. "Acceptable" studies from the open literature papers that pass the ECOTOX and OW screens of applicability should be considered potentially relevant for inclusion in the AWQC effects assessment and should be obtained for further review. 2.2 Studies Accepted by ECOTOX but not by OW After studies from the open literature that pass the ECOTOX applicability criteria are obtained, an additional [title and abstract] scan of the "acceptable" studies should be conducted to identify - Page 8 of 178 - ------- studies with taxa that are not relevant to AWQC (e.g., strictly terrestrial species). If non-relevant studies are identified, the studies will follow the process outlined in Section 2.3. All remaining acceptable studies will be further reviewed. Additional discussion of the review of studies and documentation for use in AWQC development is provided in Sections 3 and 4, respectively. 2.3 Studies Rejected by either ECOTOX or OW Open literature studies found not acceptable for ECOTOX or OW, based on the factors summarized in Section 2.1 and 2.2, are not typically used to derive AWQC; however, they may provide some useful information for AWQC development. Studies that do not meet the criteria for ECOTOX are designated as "non-applicable," and are given rejection keywords (see Attachment C), which can be cited to explain the reason for excluding a study from consideration. The EPA, may review these rejected studies, if appropriate, to determine whether the study includes information useful to the effects assessment or effects characterization. For example, studies may be rejected by ECOTOX because they include data on mixtures of chemicals. Studies that are coded with the rejection code "MIXTURE" during the initial evaluation may still be considered as a "line of evidence" during AWQC development. Other studies that are likely to be rejected by ECOTOX, but that may be useful to the EPA, as a "line of evidence" include those with data related to modeling, monitoring, incident reports, and review articles. 2.4 Consideration of Papers in the "Other" Category In addition to providing citations for "acceptable" (i.e., acceptable for ECOTOX and OW) and "rejected" (i.e., not acceptable for ECOTOX or OW) studies, a file of citations called "Other" is provided to the EPA as part of the ECOTOX search. The "Other" category documents citations for studies into one of the following four categories: (1) Target (for pesticides): toxicity of chemical on intended pest including efficacy studies; (2) On Order: potentially acceptable but publication has not been received; (3) To Abstract: applicable but not coded; and (4) To Apply Criteria: potentially acceptable but not evaluated. Papers included in the "Other" category are not coded into ECOTOX and do not appear as "applicable" data. Depending on the chemical, citations for "target" data are routinely included, whereas citations from the other three categories of "on order," "to abstract" and "to apply criteria" are encountered less frequently. In an effort to address the omission of information included in the "Other" category, all citations listed in the ECOTOX file name "Other" should be reviewed for potential inclusion in acceptable studies category. - Page 9 of 178 - ------- 3 Reviewing the Open Literature All studies identified through ECOTOX or other relevant sources that are identified as potentially useful based on the screening process discussed in Section 2 should be reviewed and classified as described in this section. When reviewing ecotoxicity data, it is important to have a systematic method for reviewing and evaluating the quality of a study. This applies to all types of ecotoxicity studies that have the potential to be included in AWQC development (e.g., single-species toxicity data, multispecies laboratory studies, mesocosm studies, and field tests). Information that should be considered when evaluating the test data quality includes: • species and test properties (e.g., age, weight, lifestage) • test compound and dosing (nominal and measured doses) • dosing methodology (static, static renewal, or flow-through) • exposure duration (acute or chronic, or subchronic) • water quality data during the test (dissolved oxygen levels, pH, temperature, etc.) • ecotoxicological endpoint data for both control and treatment groups • statistical methods used to analyze the test results • any unexpected observations or unusual circumstances that would be important in the interpretation of the test (e.g., tank overflow, malfunction of aeration system) High quality data should be both relevant and reliable for AWQC development. The Information Quality Act of 2001 (Data Quality Act) charged the Office of Management and Budget (OMB) with issuing government-wide guidelines that "provide policy and procedural guidance to Federal agencies for ensuring and maximizing the quality, objectivity, utility, and integrity of information (including statistical information) disseminated by Federal agencies." In 2002, the OMB issued Information Quality Guidelines and the EPA then developed the policy and procedural guidance, Guidelines for Ensuring and Maximizing the Quality, Objectivity, Utility, and Integrity of Information Disseminated by the Environmental Protection Agency (EPA/206R- 02-008, October 2002). Data quality, as defined by OMB and in the Informational Quality Guidelines, is the overarching data condition that must be determined by evaluating each of the following: 1. Utility refers to the usefulness of the literature to its intended purpose and use. Studies, data, information and methods must only be relied upon to the extent their use is scientifically justified. 2. Objectivity refers to whether the information in the study is presented in an accurate, clear, complete, appropriate, and unbiased manner. - Page 10 of 178 - ------- 3. Transparency refers to the clarity of the process. For example, uncertainties and error sources, assumptions, statistical methods, and justifications must be identified, as this high degree of transparency facilitates reproducibility by third parties. 4. Integrity refers to ensuring the information is not compromised through alteration or improper interpretation. In the derivation of AWQC, ecotoxicity data need to be particularly evaluated based on three major points: 1) relevance to criteria derivation; 2) level of documentation; and 3) acceptability. The level of documentation and acceptability together define the reliability of a study. The ECOTOX system for documentation of aquatic and terrestrial toxicity data from laboratory and field studies is widely accepted. International jurisdictions use similar processes (e.g., Dutch National Institute for Public Health and the Environment (RIVM) 2001) and acceptance criteria (e.g., Klimisch et al. 1997) in the data evaluation process. To minimize uncertainty in AWQC, only data that meet stated data quality guidelines should be used for criteria derivation (Section 3.2.2), Toxicity and physical-chemical data should be from studies conducted according to accepted protocols that are appropriate for the chemical and organism being tested. As in vitro methods develop, technical support information on accepted protocols will be incorporated. Some international jurisdictions simply state that tests must have been conducted according to accepted, standardized protocols or according to principles of good laboratory practices (GLP) while the U.S. EPA (U.S. EPA 1985, U.S. EPA OSCPP Section 850 Guidelines for aquatic species) and European Commission (2011) list very specific data requirements. 3.1 Study Classifications Studies identified in ECOTOX and other sources that may provide data relevant to criteria derivation should be reviewed and classified. Data should be classified into one of three general categories: • Quantitative: Appropriate for use in AWQC derivation or other quantitative measures of effect (e.g., Sensitivity Distribution development, acute-to-chronic ratio calculation); • Qualitative: Not appropriate for quantitative use, but of sufficient quality to be used descriptively; for example, as a line of evidence in the effects assessment; and • Unacceptable: Inappropriate for quantitative and qualitative use in AWQC development due to insufficient quality and/or lack of scientific defensibility. General guidelines for reviewing open literature studies and identifying data usability from a study as "quantitative," "qualitative," or "unacceptable" are provided in the following section (Section 3.2). -Page 11 of 178- ------- 3.2 Guidance for Open Literature Data Review The 1985 Guidelines provides guidance to enable classification of data from open literature studies into one of three categories, as discussed in the preceding section. OW has developed this SOP document as an enhancement to the 1985 Guidelines, to support transparency and consistency in evaluations. The approach outlined in this SOP document is based on the 1985 Guidelines and additionally reflects information available in the EPA OCSPP Series 850 Ecological Effects Test Guidelines for aquatic and aquatic-dependent species. Prior to development of this SOP, OW a conducted a review comparing OW's data quality and test acceptability guidelines for the review of open literature studies on aquatic and aquatic- dependent species, as presented in the 1985 Guidelines, with OPP's 40 CFRPart 158 requirements and guidance on reviewing open literature studies (U.S. EPA 2011) for the evaluation of data quality and test acceptability under the Federal Insecticide, Fungicide, and Rodenticide Act (7 U.S.C. § 136 et seq., 1996). The results of this review indicate that test acceptability and data quality requirements do not differ substantively between the two programs, and that data would generally be excluded or included based on similar data quality requirements. The approach outlined in this SOP document is also generally consistent with data quality and test acceptability criteria applied in data quality review for aquatic and aquatic- dependent species' data by the EPA's Office of Pollution Prevention and Toxics under the Toxics Substances Control Act (15 U.S.C. §§ 2601 et seq., 1976). EPA reviewers also apply their best professional judgment to determine the appropriate classification for aquatic toxicity studies. The templates for taxa-specific Data Evaluation Records (DERs) found in Attachment D of this document include detailed information for the study reviewer on specific attributes necessary to consider a study acceptable for use in criteria development. The information in the DER templates on specific attributes of a study reflect the EPA (1985 Guidelines, 1995 Addendum, and EPA OCSPP's Series 850 Ecological Effects Test Guidelines), ASTM (American Society for Testing and Materials), and OECD (Organisation for Economic Co-operation and Development) standardized test guidelines. The sources for each specific attribute of the study are cited on the DER. While a single factor may result in a study being considered unacceptable (e.g., excessive control mortality), more typically, several factors in combination render a study unacceptable. The following should be considered when evaluating open literature studies: • Data used in derivation of AWQC. The data should be from a primary source published in English and available either as a publication or in the form of a dated and signed document (e.g., manuscript, memo, letter; U.S. EPA 1985). Reports should include enough supporting information to evaluate the acceptability of test procedures and reliability of study results. Unpublished studies deemed useful for criteria derivation should undergo focused the EPA review, and in some cases external peer review, prior to usage in criteria derivation. The 1985 Guidelines (U.S. EPA 1985) and associated Technical Support Document (U.S. EPA - Page 12 of 178 - ------- 1987) provide specific data quality guidance and information on quality criteria for acceptance/rejection of toxicity tests. This SOP document summarizes and updates previous data quality information found in the 1985 Guidelines (U.S. EPA 1985) and the Technical Support Document (U.S. EPA 1987). • Nature of the test substance (percent active ingredient; source/manufacturer). The study should indicate the exact nature and source of the chemical toxicant being tested, including the grade and purity. Data for test substances less than 80% pure and chemical mixtures are typically deemed unacceptable (e.g., drilling muds, effluents, sludges), but may be considered on a case-by-case basis. For most metals, acceptable data for only a few salts (chloride, nitrate, and sulfate) are used quantitatively. Data for other salts are typically classified as either qualitative or unacceptable but may be used on a case-by-case basis. If the chemical is a pesticide, the percent active ingredient and/or the purity of the test compound should be reported. If a vehicle is used for solubilization of the chemical in the test dilution water, the vehicle should be identified and should be known not interfere with the absorption, distribution, metabolism, or the elimination (ADME) of the test substance, nor alter the behavior/response of the test organisms. Toxicity studies which rely on solvents should include solvent controls to document that the solvent did not affect the organism response. • Species, age, sex, size, and life stage and source of the test species. The test organism should be identified by scientific name and the health of the test organism should be reported. The test organisms, to the extent possible, should be of uniform weight, size and age, and life stage, and have no history of pre-exposure to other chemicals. Any acclimation of test organisms prior to testing should be reported and adhere to established protocols (e.g., U.S. EPA or ASTM). Observed diseases and treatment should be reported and may disqualify test animals or a specific study from quantitative use. Data obtained with species non-resident in North American were previously generally categorized as unacceptable and rejected without further review based on discussions in the 1985 Guidelines. Current scientific approaches reflect the interest in considering all quality toxicity tests on aquatic species as potential surrogate data for the thousands of untested species in the environment and thus may be included on a case-by-case basis in the systematic review process, so that data needed to fill information gaps is not unnecessarily excluded without appropriate consideration of their utility. Species native to temperate regions are considered more representative surrogates for potential untested species in the U.S. than tropical species. • Method of chemical addition and exposure. The test material is typically dosed to the dilution water by either static, static-renewal or flow-through procedures. Acute tests can use any of these three methods, if the chemical is known to be sufficiently stable in water over the test duration, but chronic tests should use either static-renewal or flow-through procedures. Data from tests in which the test organisms were exposed to the test material by injection or gavage are typically classified as unacceptable, but may be considered as part of - Page 13 of 178 - ------- the weight of the evidence. Data from tests with dietary exposure will be considered for bioaccumulative chemicals. • Number of organisms tested per concentration/dosage level and number of concentrations/dosage levels evaluated, as well as the number of replicates for each concentration/dosage level. This type of information should be reported and be sufficient to yield statistically-sound results. An inadequate number of test organisms per test level or not randomly assigning test organisms to the different treatments, can produce unreliable results. U.S. EPA (e.g., Office of Chemical Safety and Pollution Prevention 850 Draft or Final Test Guidelines2) or ASTM standardized test guidelines should be consulted for further information on the adequate number of test organisms per test level and on assigning test organisms. Data from tests in which enzymes, excised or homogenized tissue or cell cultures can be considered in examining adverse outcome pathways or used if a quantitative relationship between the effect and an apical endpoint (e.g., survival, growth, and reproduction) has been determined. • Quantification of exposure. The concentration (and total volume of test material administered, if available) in water or sediment should be reported, as well as the type of test (static, renewal, flowthrough) and duration of exposure. For all studies, the exposure conditions should be clearly described and documented. Measured concentrations are strongly preferred over nominal concentrations for acute tests, while measured concentrations are required for chronic tests and field studies. Measured and nominal concentrations should be reported. Measured concentrations should be analyzed according to procedures set forth in standardized analytical chemistry test guidelines, such as USEPA, ASTM standard test guidelines or other analytical methods determined to be of high performance (e.g., documented research method). Measured concentrations should not vary excessively during the study period. Studies should not be used quantitatively where measured concentrations deviate more than identified as acceptable in the published analytical method. Studies should also not be used quantitatively if variability in concentration between the different treatment groups is sufficiently high (e.g., results deviate by more than 20%) to render mean exposure concentrations between the different treatment groups statistically indistinguishable and/or overlapping concentrations occur between different treatments. The following factors should be considered when reviewing a study with high variability between treatment group measured concentrations: a) the treatment group with high variability is not an endpoint of concern (e.g., different than the no observed effect concentration [NOEC] or lowest observed effect concentration [LOEC] value); b) the dose-response is strong despite the +/- 20% variance; c) the frequency and duration of occurrence (i.e., variance at a low frequency vs. all the time); d) the study authors have provided justification for variability in measured concentrations and identified all measures 2 https://www.epa.gov/test-guidelines-pesticides-and-toxic-substances/series-850-ecological-effects-test-guidelines - Page 14 of 178 - ------- taken to mitigate the problem; and e) the duration of the study (i.e., <20% variability is rarely achieved in fish full lifecycle studies). Where only nominal concentrations are reported, the reviewer should consider whether the test compound is subject to degradation, volatilization, partitioning and/or a combination of these properties such that exposure levels may be considerably different than any reported nominal values (discussed under "Test chemical properties"). Additionally, the reviewer should consider whether test conditions could allow exposure to other chemicals that could potentially confound the study outcomes. • Control conditions and performance. A suitable number of controls should be run concurrently with treatments, and control performance should be used as an indicator of whether study conditions and animal health are acceptable. Negative controls should be run concurrent with the study and failure to do so would typically invalidate the study; exceptions can be made under special circumstances (e.g., lab with a strong history of known, non-variable control responses and outcomes with toxicants consistent with other studies). Positive controls should also be run with a reference toxicant if organisms are field collected or if sublethal biochemical endpoints are assessed to ensure responsiveness of the organisms tested. Studies which rely on co-solvents should also report concurrent solvent control performance. As an indicator of study conditions, control performance in terms of mortality and disease should be carefully evaluated and reported to determine the adequacy of the study. For most species, mortality of greater than 10% in controls for acute tests and greater than 20% in controls for chronic studies is sufficient to invalidate studies. Ideally, studies should also report the measured concentrations of test chemical in the controls. Studies reporting test chemical residues in the controls greater than the limit of detection (LOD) should be invalidated, as the ability of the study to discriminate a treatment effect may be compromised. Exceptions may occur for naturally occurring test materials (e.g., copper, other metals, various salts) and in situations where the presence of the test material in controls can be discounted given acceptable performance in the controls and where effect concentrations in the treatment groups are orders of magnitude higher than the control. Normal growth/development times (where available) for the tested species should be compared to those reported for the study controls. Where the growth/development of the control organisms differs substantially from normal reported values, the reviewer must determine whether study conditions have impaired the organisms' ability to thrive. In cases where growth or development in the controls is substantially different than typically observed for the test organisms, the study results should not be used because the ability to distinguish treatment effects is uncertain. • Wild-caught animals. Tests using wild-caught animals with unknown previous exposure histories are acceptable provided their source is not an area where prior exposure to pollutants is likely. Test organisms that are reported as having been previously exposed to the test material or other contaminants are invalid. Likewise, wild caught test organisms collected from water with high natural concentrations of potential environmentally-derived toxicants (e.g., metals) should not be used. Also, wild caught animals used in tests that are not quarantined and sufficiently acclimated should be invalidated. Documentation of - Page 15 of 178 - ------- quarantine and acclimation should be available for all wild caught test organisms used in toxicity tests. As an exception, wild caught organisms collected from high and low exposure sites may be used to generate an exposure gradient for maternal transfer studies for certain chemicals (e.g., selenium maternal transfer studies where effects were observed in offspring). • Macroscopic observations of the test animals. During a study, a detailed description of the nature, incidence, time of occurrence, severity, and duration of all observed effects, including death and any other abnormal or unusual signs and symptoms (i.e., sublethal effects) should be reported for controls and treatment groups. • Husbandry and test conditions. Standardized conditions (U.S. EPA OSCPP 850 Guidelines, ASTM studies) have been established in part to minimize the potential for husbandry conditions to confound the study outcome. Reviewers should be cognizant of husbandry conditions and verify that the study conditions are adequately described and acceptable. This description should include: o number of animals per cage or test container (i.e., biological loading rate) o test organism health (treatment or observation of disease/stress should be reported) o ambient temperature (use of water temperature outside the range of values that are acceptable for the test species is invalid, unless temperature-related responses are an experimental factor) o humidity (as applicable) o photoperiod o dietary composition and feeding rate o source of food o dimensions of the test container o source of the dilution water and description of its chemical characteristics (use of distilled or deionized water without reconstitution is invalid) o description of the toxicant delivery system and flow rate (expressed as the average water volume of test solution passing through each test chamber per unit time). Reviewers should consider whether the water exchange (static, static renewal, or flow- through conditions) is adequate to support the number of test animals in the selected test chambers and is appropriate given the test chemical's stability. Control performance and variability should be used as an indicator of the test environment suitability. Results from tests using nonstandard protocols are acceptable for use if the conditions described above are adequately documented and no unexplained irregularities are observed. • Feeding during acute tests. Results of acute tests during which test organisms were fed should not be used (except for tests using certain species such as saltwater annelids and mysids) unless data indicate that food did not affect the toxicity of the test material and/or the test material has a low Kow value (< 2). For compounds with a log Kow of less than two, the presence of food is assumed to be not likely to significantly alter the dissolved concentration - Page 16 of 178 - ------- or bioavailability of the test material. For pesticides with log Kow values between 5 and 7, laboratory toxicity data should be carefully reviewed to ensure that feeding regimes are eliminated to minimize any effects from interaction of the pesticide with food particles (e.g., reduction of test solution concentration as a result of partitioning into the food particles, or introduction of a dietary exposure route if animals ingest food that has sorbed to the pesticide, if the test is intended to capture only water column-based effects). • Test chamber material. Tests conducted with organic materials in plastic test chambers (test vessels constructed from materials other than glass) without measurement of test material should be considered invalid unless it can be confirmed that the test material is stable and/or has a low Kow value. Tests conducted in plastic test chambers should be documented in the study evaluation because there is the potential for plasticizers to leach into the dilution water, which could compromise the test results. • Test chemical properties (e.g., solubility, Kd and Koc, vapor pressure/Henry's law constant). This information is important in determining if actual exposure concentrations could differ substantially from nominal concentrations and where it might be critical to have measured values throughout the study. The U.S. EPA OCSPP Guideline 850.1000 (Draft; U.S. EPA 1996) provides useful guidance on the design and conduct of aquatic studies with difficult to test substances and should be considered when determining the acceptability of a toxicity study. The solubility and stability of the test material should be known for the conditions under which the test is being conducted to provide scientifically defensible information. This representative analysis of the material should be conducted under the same conditions as those used for the test. The limit of detection (LOD) and limit of quantification (LOQ) for the chemical being analyzed should be identified. Incomplete dissolution of materials with low water solubility, such as evidenced by the presence of precipitates or films in or on the water could affect actual exposure levels, and the solubility of the chemical in relation to the reported test concentrations should be considered when evaluating such a test outcome. The use of aerated treatment units when testing a chemical that is volatile is likely to overestimate exposure concentrations, and should be considered invalid, unless exposure concentrations are regularly measured. For any chemicals where stability, solubility, volatility, and/or sorption may be issues, chemical measurements at the study initiation and termination are considered important and should be considered when determining the validity of the test. • Water quality. All relevant water quality parameters (e.g., dissolved oxygen, temperature, pH) should be reported. Hardness, Dissolved Organic Carbon (DOC), and pH are crucial for the evaluation of metals toxicity, particularly for those where bioavailability is affected by these parameters. However, results of acute tests conducted in dilution water with total organic carbon or particulate matter exceeding 5 mg/L should not be used, unless a relationship between acute toxicity and organic carbon or particulate matter has been established and/or data show that organic carbon, particulate matter, or similar substances do not affect exposure/toxicity. In addition, biological loading rates should be suitable for the - Page 17 of 178 - ------- test container and not compromise water quality during the study. For water column tests, mean dissolved oxygen concentrations should not drop below 60% saturation for prolonged periods, unless justification is provided indicating the dissolved oxygen suppression did not interfere with the test outcomes. • Negative and solvent control performance. The concentration of organic solvent in test solution should not exceed 0.1 mL/L for acute and/or chronic invertebrate studies or acute fish flow-through studies; the solvent should not exceed 0.5 mL/L for acute fish static or static-renewal studies (see the appropriate comparable U.S. EPA or ASTM study guideline). OPP has developed guidance (U.S. EPA 2008) for aquatic studies with pesticides for determining whether negative and solvent control performance is adequate. This guidance should be considered when determining whether an aquatic toxicity study conducted with high Kow organic compounds is valid. • Endpoint selection. Measured toxicity outcomes should be representative and applicable to the assessment endpoint being evaluated (e.g., risks to species, populations, communities). For acute tests, these endpoints would typically include acute median effective concentration (ECso) or median lethal concentration (LC50) values. For chronic studies, endpoints may include NOEC and LOEC, and/or preferably ECx (e.g., EC 10 or EC20) values. Where toxicity data are available for multiple life stages of the same species (e.g., eggs, juveniles, adults), OW uses the data from the most sensitive life stage to develop AWQC. This helps to ensure that a given species can survive an exposure during the most sensitive stages of its life cycle, and thus maintain a viable population. Studies reporting sublethal endpoints other than those traditionally used in AWQC development may be used qualitatively as additional lines of evidence to support tests that report direct effects on survival, growth, and reproduction. Sublethal effects can include hormonal, biochemical, cellular, osmoregulatory, and behavioral measurement endpoints, among others. Some of these endpoints, such as adaptational behaviors (e.g., predator avoidance, feeding behaviors), reproductive behaviors (e.g., mating behavior, nest guarding behavior), and morphological effects are important to the overall fitness of both the individual and the population. Consideration should be given to whether there is a quantitative relationship between the observed sublethal effect and an effect that is relevant to organism and/or population viability and is of regulatory concern (e.g., survival, growth, reproduction). These types of endpoints (Kramer et al. 2011) may also be linked via Adverse Outcome Pathways (AOP) for survival and reproduction to population- level effects in aquatic animals (Ankley et al. 2010). • Statistical methods used to analyze the test outcome. Verification of the statistical analysis is an integral part of the data evaluation process. As such, studies should report the specific measures of central tendency (e.g., means, medians) and dispersion (e.g., standard deviations, standard errors) that were used, along with associated sample sizes (N values). The report should state which methods of statistical comparison (e.g., t-test, ANOVA, chi square) were used and the assumed data distribution (parametric versus nonparametric). Tests using parametric statistics should indicate whether the conditions for such tests (i.e., normal - Page 18 of 178 - ------- distribution and homogeneity of variance) have been met. Specific statistical software used should be identified. • Information necessary to provide a complete and accurate evaluation of test outcomes. Each report should include a summary of the data, a description of the statistical analysis of the data, and a statement of conclusions drawn from the analysis that allows the reader to independently evaluate the conclusions of the author. The availability of raw data is particularly important when needed to recalculate an endpoint for a study that could substantively affect the criteria value (e.g., studies indicating effects near the 5th percentile), and efforts should be made to obtain the raw data from the study author if these data are not reported in the study. • Important information to determine study reliability. Inconsistencies or deviations with recommended methodologies should be reported, as discussed in the applicable guidelines (U.S. EPA guidelines, ASTM test methods, and/or OSCPP guidelines Standard Evaluation Procedure [SEP]), for each of the respective studies. The U.S. EPA specific test guidelines can provide additional measures to gauge the reliability of study conditions. 3.2.1 Studies Classified as Unacceptable Open literature studies classified as unacceptable are those that are not considered sufficiently scientifically rigorous for use in criteria derivation and do not provide useful and/or reliable information. Studies classified as unacceptable can include those performed under conditions that deviated so significantly from the recommended protocols that they bring into question the validity of the toxicity test results. Aquatic studies commonly placed in this category include those with improper test conditions (e.g., static exposures with volatile chemicals in aerated test chambers), test vessels constructed of materials other than glass coupled with a test substance that is expected to sorb to the test chamber walls, excessive mortality of control animals, substantial amounts of missing test information, a study where the test material was not properly identified, and/or environmental conditions or results that cannot be readily interpreted from the information provided. A detailed list of factors that could result in invalidation of open literature data is provided above in Section 3.2. 3.2.2 Studies for Quantitative and Qualitative Use If a study is determined to be acceptable based on the guidelines described above, a determination is made regarding whether the information provided in the study is adequate for "quantitative" or " qualitative" use in AWQC derivation. For OW's purposes, 'quantitative' means the data from the study can be used to derive a numeric AWQC. " Qualitative" refers to data that are not adequate for the derivation of numeric aquatic life criteria, but that can be used as additional lines/weight of evidence to support the effects assessment as described in the - Page 19 of 178 - ------- effects characterization. As previously discussed, to be used quantitatively, the endpoint(s) reported in the open literature should meet all the following general guidelines: • The endpoint is reported in (or can be converted to) acceptable units (e.g., |ig/L) • The endpoint reported can be used to derive AWQC (e.g., LC50 for acute exposure in fish) for apical endpoints of concern: survival, growth and reproduction; and • Sufficient information is provided in the study to substantiate or independently evaluate whether the reported study conclusions (i.e., dose-response) and endpoints are accurate. Depending on the measured endpoint, study evaluation criteria similar to those in OCSPP 850 Test Guidelines or ASTM methods, should be used to gauge the utility of the study. If a study does not contain sufficient information to meet the key acceptance criteria including the general guidelines summarized above in this SOP, the data from the study should be classified as "qualitative." OW recognizes that the third criterion of "sufficient information" listed above requires best professional judgment. The most reliable means of determining whether study conclusions can be verified is through accessing the raw data for a study; however, it is recognized that many open literature papers, particularly older ones, may not provide this type of information. Therefore, the quantitative use of open literature requires that the study provide a relatively comprehensive description of the conditions under which the study was conducted, and the data generated by the study. The study should report detailed measures of the variability associated with the data and the methods used to analyze the data. Reviewers should note whether the statistical tests used in the study are appropriate for the study design, the nature of the measured endpoints, and the data generated by the study. Where raw data are not available to verify the study endpoints, the reviewer should discuss the uncertainties associated with quantitative use of the data. Consideration should be given to the extent to which the measured test endpoints align with other lines of evidence. 4 Documentation of Open Literature Used in AWQC Development This section discusses the process of tracking and documenting studies obtained from the open literature through the screening (Section 4.1) and reviewing process (Section 4.2), and how this information is presented in AWQC documents (Section 4.3). 4.1 Documenting Study Screening Outcomes - Page 20 of 178 - ------- All studies identified through an ECOTOX search or other relevant searches should be documented throughout the screening process. The files provided with the results of the ECOTOX database search and screen can include the studies accepted by ECOTOX as well as studies considered non-applicable with defined rejection reasons and "other" studies with identification terms. These files should be retained to document which studies require further review and which studies do not. The files should also be updated if studies are found from sources other than the ECOTOX database and in cases when a study is accepted by ECOTOX but not by OW. 4.2 Documenting Study Review Outcomes Studies identified in the open literature (ECOTOX and other sources) that may provide data relevant to criteria derivation should be reviewed and classified (i.e., quantitative, qualitative, unacceptable), and the evaluation should be documented as described in this section. Data Evaluation Record (DER) templates have been developed by OW to describe specific recommendations for toxicity test aspects and to document review outcomes for studies considered for use in AWQC development. The purpose of completing the DER for each study as outlined below is to ensure a transparent, efficient, and consistent process for completing and documenting reviews of studies and avoiding duplicative and possibly conflicting conclusions associated with study reviews by different reviewers. The EPA is using an electronic format of the DERs housed under the EPA's ECOTOX database. The information captured in the DER is identical to those included below. In the future, the information captured in the DER could be captured in another electronic format. DER templates for fish, aquatic and terrestrial invertebrates, plants, amphibians, and avian species are included in Attachment E through Attachment J. Data Evaluation Records (or an equivalent documentation approach) should be completed: • For open literature studies that pass the initial screening phase as described in Section 2. • For all studies with acceptable endpoints that are classified as 'quantitative,' 'qualitative,' or 'unacceptable' as described in Section 3. o 'Unacceptable' studies receive an abbreviated DER review, as noted below. • By a primary and secondary reviewer. The DERs are separated into three parts: • Part A includes a general overview (citation, summary of any deficiencies, study classification [quantitative, qualitative, unacceptable]), abstract, summary of relevant endpoints, and results. • Part B includes information on materials and methods. - Page 21 of 178 - ------- • Part C includes verification of calculations and statistical results (if raw data are provided or obtained from the study author, and statistical re-analyses are deemed useful or important). The DERs should be saved with a file name that includes: • Chemical (e.g., "Hg" for mercury) • Taxonomic group (e.g., "invert" for invertebrate) • Species name or common name (e.g., "C. dubia" or "Cladoceran"). If data for more than one species are provided in the paper, then use term that best conveys the information (e.g., "multiple inverts") • Abbreviated citation beginning with year published followed by first author (e.g., year and first author [et al.]) • Reviewer's initials and date For example, BaCl_Fish_ D. rerio _2016_Kwon et al._ CB_05-09-19 would be the file name of the study review completed by "Catherine Brown" of: Kwon, B., N. Ha, J. Jung, P.G. Kim, Y. Kho, K. Choi and K. Ji. 2016. Effects of barium chloride exposure on hormones and genes of the hypothalamic-pituitary-gonad axis, and reproduction of zebrafish (Danio rerio). Bull. Environ. Contam. Toxicol. 96(3): 341-346. The procedures for completion of the DERs for endpoints that are classified as "quantitative", "qualitative", or "unacceptable" are described below. 4.2.1 Completion of DERs for Endpoints Used Quantitatively DERs of open literature data and other studies that are used quantitatively to derive numeric criteria should be completed in their entirety (i.e., Parts A, B, and C). The DER should include: the basic study requirements, such as test organism source/acclimation, use of solvent and negative controls, control mortality rates (or other issues with controls that could affect the study validity), number of test concentrations, number of treatments (e.g., 3 applications, 7-day application interval), water quality parameters, and verification of suitable replication. The review should also document all statistically or biologically significant effects. In addition, the duration of exposure, the magnitude of the effect, and the test concentration (nominal, measured, and time-weighted average, if it can be determined) at which the effect was observed should be documented. Each documented endpoint should specify the affected taxa and/or individual species. In addition, the reviewer should include relevant figures and tables from the study that include key findings (e.g., a screenshot from the publication); table and figure captions should properly cite the relevant publication if the figure and/or table is copied from the publication. Statistical software and methods (e.g., R, TRAP, BMDS, with associated version number/date identified) used to verify the reported study or test results and calculate point estimates should be completed when possible and deemed necessary, and reported in Part C. This step may occur separately in time, after Parts A and B have been completed. All open literature studies that are - Page 22 of 178 - ------- classified as 'quantitative' and used to derive criteria should undergo two levels of internal review, including a primary review of the study, typically by the EPA contractor, and a secondary review by staff typically within OW's Ecological Risk Assessment Branch (ERAB). In the future the information captured in a DER could be captured in another electronic format. 4.2.2 Completion of DERs for Endpoints Used Qualitatively DERs should be completed for open literature studies that include endpoints to be used qualitatively in criteria development. To the extent possible, DERs for qualitative endpoints should include the same type of information and level of detail as reviews that are completed for quantitative endpoints, but only through Parts A and B. In addition, DERs for qualitative endpoints should include a description of the study limitations which preclude its quantitative use. 4.2.3 Completion of DERs for Unacceptable Open Literature Studies For those open literature studies that are classified as "unacceptable," DERs should be completed, however, the length and level of detail relative to "quantitative" and "qualitative" reviews should be significantly reduced. The abbreviated DER for unacceptable studies should consist of Part A only and focus on the limitations of the study which preclude its use in criteria development. Detailed description of the experimental design is not required for studies that are classified as "unacceptable," however, screenshots of figures and tables of relevant results should be included. 4.3 Open Literature Review Documentation in A WQC Documents Studies identified that may provide data relevant to criteria derivation and are reviewed and classified as quantitative, qualitative, or unacceptable are listed as appendices in AWQC documents as described below. 4.3.1 Documentation for Endpoints Used Quantitatively Numeric AWQC development by OW is detailed in the Effects Analysis section of aquatic life AWQC documents, along with the final acute and chronic criteria (with allowed durations and frequencies). Numerous quantitative data are provided in this section, as is an overview of key drivers of the criteria magnitude. The final main section of the aquatic life AWQC document, the Effects Characterization, describes confidence and uncertainties in those studies and includes relevant qualitative studies as other lines of evidence. A table listing the studies used quantitatively can also be found in appendices labeled "quantitative toxicity data" (previously referred to as "acceptable toxicity data" in aquatic life AWQC developed prior to 2017). This table includes relevant study information including, but - Page 23 of 178 - ------- not limited to, the species tested, notes on the test method (e.g., static versus flow-through), test material, water quality, acute or chronic effect value, and the study reference. 4.3.2 Documentation for Endpoints Used Qualitatively Although endpoints from studies that are classified as 'qualitative' are not appropriate for quantitative use (i.e., numeric AWQC derivation), they should be discussed in the Effects Characterization section of the AWQC document as additional lines of evidence to support conclusions. A clear rationale should be provided in an appendix. The Effects Characterization section of the AWQC document should focus on how these studies provide supporting lines of evidence and briefly reference why the endpoints were not used quantitatively. These reasons might include test duration, limitations in the study design, lack of sufficient information to substantiate the test results/conclusions, or other uncertainties that confound the ability to discriminate a quantitative treatment-related effect. As previously stated, best professional judgment should be used to determine the appropriate use of studies in criteria development. A table listing the studies categorized as qualitative can also be found in appendices labeled "qualitative toxicity data" (previously referred to as "other toxicity data"). This table includes relevant study information including, but not limited to, the species tested, test material, test duration, water quality, acute or chronic effect value, species mean acute or chronic value (SMAV or SMCV), the study reference, and notes on the reason it is categorized for qualitative use. 4.3.3 Documentation for Unacceptable Endpoints To create and maintain a record of all studies reviewed and considered in criteria development, a table listing the studies determined as unacceptable for use is also included in appendices labeled "unacceptable toxicity data" (previously referred to as "unused toxicity data") in each AWQC document. This table includes the citation and rationale for considering the study unacceptable for criteria development. - Page 24 of 178 - ------- 5 References Ankley, G.T., R.S. Bennett, R.J. Erickson, D.J.

Acute-chronic ratios can be calculated with data from species of aquatic animals from at least three different families if the following data requirements are met: o at least one is a fish; o at least one is an invertebrate; and o for freshwater chronic criterion: at least one is an acutely sensitive freshwater species (the other two may be estuarine/marine species) or for estuarine/marine chronic criterion: at least one is an acutely sensitive estuarine/marine species (the other two may be freshwater species). • At least one acceptable test with a freshwater alga or vascular plant is required. If plants are among the aquatic organisms most sensitive to the material, results of a plant in another phylum should also be available. - Page 27 of 178 - ------- • At least one acceptable bioconcentration factor determined with an appropriate freshwater species is required. - Page 28 of 178 - ------- Attachment B Acceptability Criteria for Aquatic Effects Data ECOTOX Reference No.: General instructions: If more than one experimental design is used in the study, multiple Literature Acceptance Criteria Checklist forms may be required, but the acceptability of the paper is based on at least one experimental design meeting all the Acceptability Criteria. No. Criteria / Instructions Yes / No 1 The paper reports effects associated with a single chemical exposure. However, OWwill consider studies examining additivity, synergism, or antagonism of two or more chemicals where pertinent to the derivation of an aquatic life criterion. Effluents, leachates, drilling muds, fly ashes, natural- sediments, and sludges are not considered single chemicals. In addition, the single chemical cannot be introduced as a component of an effluent, etc. Formulated products, such as emulsifiable concentrates and wettable powders while considered single chemicals, may not be used for quantitative criteria derivation unless this is the only material that has valid data. The data can be used qualitatively in the effects characterization section. 2 The paper reports a biological effect on live, whole organisms or in vitro preparation. The authors clearly identify an observed effect response related to the exposure ofa live organism to the chemical of concern. In vitro studies may be considered in the criteria derivation process. "Positive" effects (e.g., increased reproduction) will be recorded and considered in the effects characterization section. 3 The paper reports a concurrent environmental chemical concentration/dose or application rate. Authors clearly report a concentration/dose or application rate associated with the observed effect response. If the study results are only available in a graphical format, add a comment to the remarks field. 4 The paper reports an explicit duration of exposure. Authors must explicitly report the duration of the exposure related to the observed effect. Durations can include qualitative terms (e.g., at hatch, at harvest). 5 The paper reports toxicology information for the pollutant of concern to OST/OW. 6 The article is published in the English language. The full article is published in the English language. Translations will not be conducted. 7 The study is presented as a full article. - Page 29 of 178 - ------- No. Criteria / Instructions Yes / No Abstracts from journal publications where the full article is published in non- English, the abstract is published in English and conference proceedings published as brief abstracts will not be considered. 8 The paper is a publicly available document. Publications that are not publicly available (e.g., internal memoranda, government reports not readily available from NTIS) may be considered. However, the documents must be made available to the public via the Federal docket when the assessment goes out in the Federal Register. In addition, certain key studies that may not be in press may be used if the reviewer is provided the opportunity to conduct an internal/external review and the author's permission to publicly disclose the information. If a registrant- sponsored study for a pesticide, all information needed for criteria derivation would need to be made available to OW through a data evaluation record (DER) or similar vehicle. 9 The paper is the primary source of the data. A document is considered a primary source if at least one of the investigators who conducted the toxicity test is an author, and the authors do not cite another publication as the original source of the data. 10 The paper reports a calculated endpoint. For the purposes of this evaluation, an endpoint is defined as the quantification of an observed effect obtained through statistics or other means of calculation for the expressed purpose of comparing equivalent effects (e.g., IC50, BCF, NOEC). If within a single experiment, the authors report the same endpoint at multiple durations, the duration most relevant to the OW's standard acceptable test durations for acute and chronic studies (e.g., 96-hr IC/ECsos will be used and note the other endpoints in the remarks field). If NOEC and IOEC endpoints are not explicitly reported by the authors, reviewers should interpret endpoints based on levels of significance reported in the paper. If more than one measurement (e.g., juveniles per litter, juveniles per females) is observed for a particular effect (e.g., reproduction), then only the most sensitive measurement will be used, and the remaining measurements are noted in the remarks field. 11 The paper reports that treatment(s) were compared to an acceptable control. - Page 30 of 178 - ------- No. Criteria / Instructions Yes / No The control treatment must be comparable to the other treatments and must be free of the chemical stressor. Appropriate controls include: baseline or background control - parameters of actual or representative test species measured before and after administration of test chemical though not as part of the same test scenario; negative control - organisms maintained under conditions identical to exposed organisms except for the absence of the test substance; positive controls - organisms maintained under conditions identical to the exposed organisms except the test substance is replaced with a substance known to elicit a consistent toxic response; and solvent controls - organisms exposed to carrier or solvent that is used as a vehicle for administrating the test substance to exposed organisms. The number of treatments (other than controls) should be reported in the data summan> table. 12 The paper reports the location of the study (e.g., laboratory vs. field). Authors clearly state the locations of the study, either in a controlled laboratory setting or in the field. Field studies are not typically used in a quantitative manner in the criteria derivation process, but may be used qualitatively to support quantitative laboratory studies. Field studies can include natural or artificial settings (e.g.. microcosms, mesocosms). 13 The paper reports the species that was tested; and this species can be verified The authors clearly identify the test species and the organism's scientific name can be verified in a reliable reference. The preferred scientific name should be reported. If a specific genus/species is not reported, reviewers report the species information at the lowest taxonomic level. -Page 31 of 178- ------- U.S. EPA OW Attachment C ECOTOX Exclusion Reasons General Instructions: The following is a list of ECOTOX exclusion keywords and definitions utilized under the ECOTOX database efforts.

All DERs should be: • Completed in their entirety (except for noted exemptions) following the instructions provided below o Do not leave sections/tables blank unless noted otherwise. Use not applicable (NA), not calculable, not provided, not verified, or not measured as appropriate • Completed for each chemical and species combination (i.e.. if a study focused on 2 separate chemicals and 2 separate species, 4 individual DERs should be completed for the one study) • Saved with a file name that follows: o DER_ Chemical_Taxa_ Abbreviated Citation (First author [et al.])_ Year of Publication_ Species Name _ Reviewers Initials - Example: DERBariumFishKwon et al._2016_D. rerio CB Part A: Overview Complete an abbreviated DER of Part A only for studies marked "Not Acceptable for Use" I. Test Information Chemical Information: Complete information as provided. Test Type: Place Xby one classification. These test type classifications should be applied when completing Part B: Detailed Review ¦ Controlled Experiments are defined here as studies where the chemical exposure and test community is manipulated (e.g.. laboratory, microcosm, and mesocosm tests regardless if conducted indoors or outdoors) ¦ Field Study/Observations are defined here as studies where the either the chemical exposure and/or test community is not manipulated and the exposure observations occur in a natural waterbody (e.g., observed effects of a chemical at a contaminated stream, lake, pond, and in-situ stream or a whole lake experiments) Reviewer Information: Complete reviewer information. Primary and secondary reviewer should be designated by the EPA project lead and will typically consist of a contractor as the primary reviewer and EPA staff as the secondary reviewer. Citation: Complete citation as noted in SOP and on DER, being sure to indicate author(s), year, study title, journal, volume and pages. Companion Papers: Provide a list of any companion papers, including other publications, reports, or theses associated with the current publication being reviewed using the same citation format noted in the SOP and on the DER. If companion papers are listed, identify if separate DERs were completed for companion papers and list file names for each of the DERs. ¦ Companion papers include separate publications reporting other aspects of the experimental design and/or results or other papers used in the development of the experimental design of the publication being reviewed EPA OWDER INSTRUCTIONS - Page 36 of 178 - ------- Attachment D Instructions for Completing Data Evaluation Records (DERs) for Toxicity Studies in the Open Literature Study Classification for Aquatic Life Criteria Development: Place Xby one classification based on the study's highest use (e.g., mark "Acceptable for Quantitative Use " only if a study has both Quantitative and Qualitative Use endpoints). ¦ This overall Study Classification for Aquatic Life Criteria Development should take the Study Design/Methods Classification (in Materials and Methods section of Part B) and Response-Curve Classification (in Statistical Verification of Results section of Part C) into consideration. ¦ Provide any necessary details related to the study's use classification for all pertinent endpoints, including non-apical endpoints (i.e., differences in the study's use classification for certain endpoints). Major Deficiencies: Check all that apply, paying attention to any noted exceptions. Checking any of these items may make the study "Not Acceptable for Use". If occurrence of mixtures is identified as a major deficiency, describe potential chemical mixtures in areas provided. Identify any other notable concerns that may classify the study as "Not Acceptable for Use" under General Notes. Minor Deficiencies: List and describe any minor deficiencies or other concerns with test. Listing any items in this section may make the study "Acceptable for Qualitative Use" (exceptions apply to field studies as noted on the DER) and listing one (particularly chemical solubility issues. anomalous or inconsistent results, previous or variable exposure, dosing via gavagc) or several items may make the study "Not Acceptable for Use". The EPA project lead will typically make this distinction in use classification. A study may be considered "Acceptable for Quantitative Use " even if one or more minor deficiencies are identified and the study results are consistent with similar studies focused on a related taxon (i.e.. up to a family level) and measured the similar endpoints. For field studies/observations check mixtures if observed effects are not justifiably contributed to single chemical exposure and uncharacterized reference sites/conditions if appropriate. If either of these are checked, that may make the study "Not Acceptable for Use". Describe potential chemical mixtures present at the site and exposure variability across the study site(s). Identify any other notable concerns that may classify the study as "Acceptable for Qualitative Use" or "Not Acceptable for Use" under General Notes. * Minor Deficiencies may include: analytical or chemical solubility issues, problems encountered with the test organisms or treatments (minor variability in concentrations, loss of replicate(s), small sample sizes, only one test concentrations), description of dilution water not provided (e.g., uncharacterized stream water or potential presence of unknown containments, high organic content, extreme hardness, pH), too few exposure concentrations, anomalous or inconsistent results, unmeasured test concentrations, previous or variable exposure, dosing via gavage, insufficient details regarding methods or analyses. ¦ For field studies/observations: Only publications with a range of exposure concentrations (i.e., study design incorporates both low and high exposure concentrations) and those where observed effects are justifiably contributed to a single chemical exposure (within a mixture of concentrations) should be considered "Acceptable for Quantitative Use."
