The Developmental Appropriateness of the English Language Arts Essential Elements for Kindergarten

Description: The developmental appropriateness of the English language arts essential elements for kindergarten children in the State of Texas was evaluated by surveying the opinions of thirty-six kindergarten teachers in one school district. A questionnaire was developed using the essential elements so that respondents could record a yes or no opinion and supply additional comments on each essential element. Ninety-seven percent of the teachers responded. The results indicated rates of agreement for developmental appropriateness by the teachers surveyed to be 100% for language, 95% for listening, 94% for speaking and reading and 81% for writing.

Guidance Document for Prepermit Bioassay Testing of Low-Level Radioactive Waste

Description: In response to the mandate of Public Law 92-532, the Marine Protection, Research, and Sanctuaries Act (MPRSA) of 1972, as amended, the Environmental Protection Agency (EPA) has developed a program to promulgate regulations and criteria to control the ocean disposal of radioactive wastes. The EPA seeks to understand the mechanisms for biological response of marine organisms to the low levels of radioactivity that may arise from the release of these wastes as a result of ocean-disposal practices. Such information will play an important role in determining the adequacy of environmental assessments provided to the EPA in support of any disposal permit application. Although the EPA requires packaging of low-level radioactive waste to prevent release during radiodecay of the materials, some release of radioactive material into the deep-sea environment may occur when a package deteriorates. Therefore, methods for evaluating the impact on biota are being evaluated. Mortality and phenotypic responses are not anticipated at the expected low environmental levels that might occur if radioactive materials were released from the low-level waste packages. Therefore, traditional bioassay systems are unsuitable for assessing sublethal effects on biota in the marine environment. The EPA Office of Radiation Programs (ORP) has had an ongoing program to examine sublethal responses to radiation at the cellular level, using cytogenetic end points. This technical guidance report represents prepermit bioassay procedures that potentially may be applicable to the assessment of effects from a mixture of radionuclides that could be released from a point source at the ocean bottom. Methodologies along with rationale and a discussion of uncertainty are presented for the sediment benthic bioassay protocols identified in this report.
