Appendix B: Checklists Table C.1 Planning and problem formulation (for both human health and environmental risk assessment) Planning and problem formulation  1 Define the management goals of the risk assessment and applicability of regulatory requirements 2 Define the and objectives of the risk assessment to clearly identify the problem 3 Generate conceptual models representing predicted key relationships between stressors, exposure and assessment endpoints 4 Identify the methodology and complexity (tier level) for analysing the risk (exposure and hazard), keeping in mind this may evolve as the assessment progresses 5 Consider multiple hazards and cumulative impacts 6 Are the data available and accessible? What are the data quality criteria? What are the data gaps and uncertainties? 7 Have the interests and concerns of affected parties been considered in formulating the problem? Table C.2 Data requirements (for both human health and environmental risk assessment) Data requirements  1 Identify the chemical, mixtures or chemical identities in mixtures / flowback / produced water / wastewater (Section 4.1) 2 Obtain chemical information, along with information of fate and behaviour of the chemical(s) in the environment (Section 4.2) 3 Gather data for the exposure assessment (i.e. chemical quantities and concentrations, exposure routes and compartments) (Section 4.3) 4 Gather data for the hazard assessment (Section 4.4) 5 Evaluate data quality (Section 4.6) and determine if further data are required 6 Determine, analyse and report on the uncertainty within the acquired data (Section 4.7.3) 7 Analyse weight of evidence to determine the adequacy of the available data as a whole (Section 4.7.4) Table C.3 Human Health Exposure Assessment Human health exposure assessment  1 Identify the chemical sources and define points of release of chemical(s). 2 Identify and define transfer pathways for the chemical(s) 3 Identify and define the receptors and exposure routes (occupational exposure and public exposure) applicable to the situation being assessed. 4 Describe, measure and / or calculate exposure concentrations for occupational exposure and public exposure. 5 Describe approach, models used and uncertainties around the data used.
