• • <br /> Corrective Action: This sentence is not necessary to the purpose of this ROD. EPA <br /> recommends that the sentence be deleted. <br /> 12. Section 1.5.4 <br /> The text should note the groundwater direction and refer the reader to Figure 1.2-3. <br /> Specific wells mentioned in the text should be identified on Figure 1.2-3. <br /> Corrective Action: Add the requested text and modify Figure 1.2-3. <br /> 13. Section 2.2.1 <br /> The text does not provide any information on the findings of the first "broad-based" <br /> studies. <br /> Corrective Action: Describe the outcome of the first studies. <br /> 14. Section 2.2.1 <br /> The text in this section states "the PCE and TCE groundwater plumes have been <br /> designated OU #1, the subject of this Record of Decision." however, as explained in <br /> previous comments, only one definition of OU #1 should be used in this ROD. <br /> Corrective Action: Revise the text to reflect the definition of OU #1 used in the <br /> Declaration of the ROD, as modified by EPA comments. <br /> 15. Section 2.2.1 <br /> The text erroneously refers to the "Draft Comprehensive RI/FS Work Plan." Whereas <br /> this document is final. <br /> Corrective Action: Correct the text. <br /> 16. Section 2.2.5.1 <br /> The text references "infrequent detections of other organics" and does not mention <br /> the detection of inorganics. <br /> Corrective Action: Describe in more detail the detections of other contaminants. <br /> Refer the reader to the table to be added to Section 5.0 (see subsequent EPA <br /> comments) which will numerically describe frequency of detections. <br /> 17. Section 2.2.7 <br /> The text states that the 1991 SWMU Engineering Report objectives were "to evaluate <br /> the potential SWMU sites" However, this report focuses on only 16 of the potential <br /> SWMU sites, not the 33 which have since been identified. <br /> EPA/R9 June 7, 1993 4/40 <br />
