risk. Similarly, reference dose should be used to <br /> determine toxicity of the total non-carcinogenic <br /> PAHs. For comparison purposes, the CPF of PAHs <br /> and the reference dose for non-carcinogenic PAHs <br /> should also be used to calculate risk values. <br /> (See Superfund Public Health Evaluation Manual, <br /> 1986. ) <br /> F. 3 .b. 3 . The potential for surface water as a pathway has <br /> not been discussed. Exposure for all scenarios, <br /> both adults and children should be addressed. In <br /> all cases, a worst case and more plausible case <br /> scenario of exposure are needed. The worst case <br /> scenario should include contaminated ground water <br /> as a potential source of drinking water. <br /> H. 1.b. In addition to the referenced sources, the <br /> following should be consulted in revising the PEA: <br /> 1. Risk Assessment Guidance for Superfund. <br /> Human Health Manual, Volume 1, EPA 9285-701A <br /> 7/89 . <br /> 2 . Risk Assessment Guidance for Superfund <br /> Envi'ronmental Evaluation Manual Volume II <br /> EPA/540/1-89/001 3/88. <br /> 3 . Guidance for Conducting Remedial <br /> Investigations and Feasibility Study under <br /> CERCLA EPA/540/6-89/-0045 10/88 . Integrated <br /> Risk Information System (IRIS) will provide <br /> the most up to date data on contaminants. <br /> H. 2 .a. Revise recommendations for remedial measures to <br /> include specific plans for further action based on <br /> new risk calculations. Include what community <br /> relations efforts will •be done (i.e. , fact sheets, <br /> public meeting) to inform the neighborhood of the <br /> action to be taken at the site. Recommendations <br /> for ground water remediation should be included. <br /> H. 2 .c. In addition to the wells indicated in this <br /> section, there was mention of a 6" well south of <br /> the former pumping house. Has it been located and <br /> properly abandoned? If not, this must be done. <br /> Tables In general all tables must be self explanatory <br /> with appropriate references and detection limits. <br /> Exposure, intake and biological assumptions should <br /> be supported by appropriate references and cited <br /> in the text as well as the tables. <br /> Table 9-A What is the significance of 11<11 . <br />
