Uncertainty Assessment Sample Clauses

Uncertainty Assessment. Uncertainties are inherent in all risk assessments. The nature and magnitude of the uncertainties depend on the amount and quality of data available, the degree of knowledge concerning site conditions, and the assumptions made to perform the assessment. A qualitative evaluation of the major general uncertainties associated with this screening assessment, in no particular order of importance, is outlined below: • No avian and mammalian life history data specific to the site were available; therefore, exposure parameters were either modeled based on allometric relationships (e.g., food ingestion rates) or were based on data from these same species in other portions of their range. Because diet composition as well as food, water, and soil ingestion rates can differ among individuals and locations, published parameter values may not accurately reflect individuals present at the site. Consequently, risk may be either overestimated or underestimated. • No site-specific data on concentrations in prey items were available. Therefore, concentrations in these prey items were estimated using literature-derived bioaccumulation models. The suitability of these models is unknown. Consequently, concentrations of COPECs in actual prey may be either higher or lower than the data used in this screen. • Literature-derived toxicity data based on laboratory studies were the only available toxicity data used to evaluate risk to all receptor groups. It was assumed that effects observed in laboratory species were indicative of effects that would occur in wild species. The suitability of this assumption is unknown. Consequently, the risk may be either overestimated or underestimated. • Dietary compositions were simplified for the site receptors to estimate concentrations in food items using bioaccumulation models. It was assumed that concentrations were similar in comparable food types. The suitability of this assumption is unknown. Consequently, risk may be either overestimated or underestimated. • Because toxicity data specific for bird and mammal species at the site were not available, it was necessary to extrapolate toxicity values from test species to site receptor species. Although scaling factors were employed (Sample and Arenal, 1999), these factors are not chemical-specific and are based on acute toxicity data. Consequently, risk may be either overestimated or underestimated. • In this screen, risks for most chemicals were each considered independently. Because chemicals ...

Related to Uncertainty Assessment

  • Conformity Assessment 1. The Parties recognize that a broad range of mechanisms exists to facilitate the acceptance of conformity assessment procedures and results thereby, including:

  • Risk Assessment An assessment of any risks inherent in the work requirements and actions to mitigate these risks.

  • Security Assessment If Accenture reasonably determines, or in good faith believes, that Supplier’s security practices or procedures do not meet Supplier’s obligations under the Agreement, then Accenture will notify Supplier of the deficiencies. Supplier will without unreasonable delay: (i) correct such deficiencies at its own expense; (ii) permit Accenture, or its duly authorized representatives, to assess Supplier’s security-related activities that are relevant to the Agreement; and (iii) timely complete a security questionnaire from Accenture on a periodic basis upon Accenture’s request. Security issues identified by Accenture will be assigned risk ratings and an agreed-to timeframe to remediate. Supplier will remediate all the security issues identified within the agreed to timeframes. Upon Supplier’s failure to remediate any high or medium rated security issues within the stated timeframes, Accenture may terminate the Agreement in accordance with Section 8 above.

  • Needs Assessment 1. The Contractor shall conduct a cultural and linguistic group-needs assessment of the eligible client population in the Contractor’s service area to assess the language needs of the population and determine what reasonable steps are necessary to ensure meaningful access to services and activities to eligible individuals. [22 CCR 98310, 98314] The group-needs assessment shall take into account the following four (4) factors:

  • PROPERTY ASSESSMENT The Buyer and Seller hereby acknowledge that the Province of Ontario has implemented current value assessment and properties may be re-assessed on an annual basis. The Buyer and Seller agree that no claim will be made against the Buyer or Seller, or any Brokerage, Broker or Salesperson, for any changes in property tax as a result of a re-assessment of the property, save and except any property taxes that accrued prior to the completion of this transaction.

  • Impact Assessment If Service Provider desires to make any change, upgrade, replacement or addition that may have an adverse impact or require changes as described in Section 9.6(c) or increase the risk of Service Provider not being able to provide the Services in accordance with this Agreement or violate or be inconsistent with DIR Standards or Strategic Plans, then Service Provider shall prepare a written risk assessment and mitigation plan (1) describing in detail the nature and extent of such adverse impact or risk, (2) describing any benefits, savings or risks to DIR or the DIR Customers associated with such change, and (3) proposing strategies to mitigate any adverse risks or impacts associated with such change and, after consultation and agreement with DIR, implement the plan.

  • Diagnostic Assessment 6.3.1 Boards shall provide a list of pre-approved assessment tools consistent with their Board improvement plan for student achievement and which is compliant with Ministry of Education PPM (PPM 155: Diagnostic Assessment in Support of Student Learning, date of issue January 7, 2013).

  • Conformity Assessment Procedures 1. Each Party shall give positive consideration to accepting the results of conformity assessment procedures of other Parties, even where those procedures differ from its own, provided it is satisfied that those procedures offer an assurance of conformity with applicable technical regulations or standards equivalent to its own procedures.

  • Security Assessments Upon advance written notice by the JBE, Contractor agrees that the JBE shall have reasonable access to Contractor’s operational documentation, records, logs, and databases that relate to data security and the Contractor’s Information Security Program. Upon the JBE’s request, Contractor shall, at its expense, perform, or cause to have performed an assessment of Contractor’s compliance with its privacy and data security obligations. Contractor shall provide to the JBE the results, including any findings and recommendations made by Contractor’s assessors, of such assessment, and, at its expense, take any corrective actions.
