d. Under alternative 2 (regarding implementability) the text does not include the uncertainty of obtaining FFA-party/local concurrence on deed restrictions, well restrictions. Further, the text dos not include the uncertainties regarding enforcement of these restrictions over time. Corrective Action: Add text to describe these uncertainties. e. Under alternatives 3 and 4 the text implies that the community would find these alternatives acceptable since a similar system was accepted at DDRW- Sharpe. However, it should not be assumed that the community concerns at DDRW-Sharp would be the same as at DDRW-Tracy. Corrective Action: State the community acceptance of these alternatives as demonstrated during the public comment period. 104. Section 9.1 The sub-title includes the injection disposal mechanism but does not include use of ponds. Corrective Action: Add surface impoundments to the title. 105. Section 9.1.1 the text in the second bullet states ". . . one or more additional air strippers . . ". This statement adds an element of uncertainty which was not included in the FS nor the Proposed Plan. Corrective Action: Delete the words "or more" from the sentence. 106. Section 9.1.1 The text in this section states "discharge of treated effluent to surface impoundments is being considered . . .". However, discharge to surface impoundments is one of the discharge mechanisms of the selected remedy. Corrective Action: Revise the text to reflect that this remedy includes discharge via injection and surface impoundments. 107. Section 9.1.1 The text indicates that monitoring is estimated to occur quarterly for two years and semi-annually thereafter for 30 years. However, actual monitoring requirements need not be determined in this ROD. Corrective Action: Add text which states that monitoring will occur in accordance with a schedule to be determined in the remedial action work plan. 24/40 EPA/R9 June 7, .1993
