It shall be the responsibility of interested Offerors to adhere to any changes or revisions to the RFP as identified in this Addendum No. 4. This documentation shall become permanent and made part of the departmental files. Attachment E: Cost Proposal Form Attachment F: Agreement No. 2012-0229-PW Dropbox Link: https://www.dropbox.com/scl/fo/0zxg80g8iozu4rwqnr5u0/AFbyIqJgGWABZYmXNKodstU?rlke y=p993gtze5tudy697hw37s2m5b&st=0vzpx4t9&dl=0 Question No. 1: Effluent Quality: The existing WRF apparently was not designed to meet the same effluent quality criteria established for the expanded WRF in the RFP, particularly with respect to phosphorus removal. The planned improvements (shown as FUTURE on the Record Drawings) to the existing aeration basin, with the addition of the basins at the end of the structure and adding the internal recycle stream, will improve the nitrogen treatment capacity but will not provide biological phosphorus removal. QUESTION: To what extent, if any, will improvements to the existing WRF be required in this expansion to bring the existing WRF Aeration Basin into compliance with the effluent quality criteria established for the new WRF? If none, please acknowledge that the blended effluent from the existing and new facilities will not meet the more stringent effluent quality criteria established in the RFP. Answer No. 1: This proposal is not to include improvements to the existing phase one. 102 Grant Avenue · P.O.
