ENCLOSURE 361.13 On page 23 of PSAR A,,oendix 2P the following statements are Appendix 2P made:
"These terraces appear to Le associated with channels on the bedrock surface. Good evidence of the association of the terraces with a bedrock channel is observed on Lines 26 and 2S (Figure 100). On these lines a zone of channeling is observed on the bedrick as well as in glacial tills in the immediate vicin ty of the terraces. These terraces appear as channel walls on Lines 26 and 28 where the bedrock erosion is more pronounced relative to the erosion on Lines 24, 30 and
- 32. The bedrock crannel trends north-south and extends to Line 44 in the north.
In the south it appears to extend to Line i4 with the exception that no channeling was observed on intermediate Lines 22 and 20 (Figure 6).
The absence of channeling on lines 22 and 20 suggests that the bedrock channel may have been eroded away in this area by glacial scouring."
PSAR, Appendix 29, Figure 6 (Bedrock Features Map) does nct reflect the bedrock channel as described above. Specifically, the' figure does not reflect the channels extend northward to line 44 or the southern extension to line 14. Provide the necessary data and -
discussion to clarify this apparent discrepanc2 361.14 Provide full size copies of the following offshore Fairfield Appendices 2P and 20 geophysical lines:
Area I - Lines 15, 17 Area II - Lines 58, 60, 25, 27 361.15 On page 8 of PSAR Appendix 2R, Westen Geophysical discusses two Appendix 2R mapped escarpment like features that they felt could be interpreted as faults. The first feature occurs on Fairfield c,.

lines 18,.26 and 28.
It is further discussed in the Fairfield Industries report incitded as PSAR Appendix 2Q.
The secont~ feature describec by '4eston as occurring on Fairfield geophysical lines 44, 15, 17 and 21, is not discussed in the remainder of the PSAR. Discuss in detail all data available concerning this feature, including fault parameters and relationship to che regional geology.
361.16 Pages 21 thru 24 of PSAR Appendix 2Q discuss four macnetic Appendix 20 anomalies, numbered I, 2, 3 and 4.
Tne PSAR references Appendix 2Q, Figure 8 for the anomalies location in the Fairfields St:.dy Area II. The location and areal extent of anomalies 1, 2, 3 and 4 is unclear as shown on Figure 8, Appendix 2Q. Please modify Figure 8 to clarify the location and areal extent of t'iese aacmalies.
