Informotton Obtained —____ _ _________________________ ——_——.—----------------— 1.) P.D. Formiah: T in-Fn-rmAd B-R. that in OUT July 18 meeting; Mr. Farag had agreed we would first submit a concept submission containing alternatives. with sufficient hydraulic data to allow selection of an altemar-ive. After selection of an alternative, we would ultimately follow the P.D. format in our final submission. I also noted this was a project for a national railroad agency, that no additional flows were being generated as a result of the project, and therefore, that certain components of the PD

I format would not be applicable!.. in particular, I rafprannad Rppg.ndir'ac aflxer "A". I suggested we could discuss applicability of the standard PD requirements after an alternative was selected. He agreed. 2.) Alternatives to be Examined; I informed R.A. that we were examining 2 rerouting alternatives — the only 2 we could identify which would not require pumping or syphons. I also noted that Amtrak had requested that we look at syphons.

3.) Original July 9 SuhmiRsion;. I informed R.A. that our snHma .giision had hpe»n based on Preliminary Engineering work done by SSVK, which showed syphons at 33rd and 34th Streets. We had made the assumption that SSVK would have checked the concept through with BOS, which they apparently did not do. r 'g tsIfixT F^firg
