Modification #2 - Addition of Modified Appendix H adding a vendor to the approved manufacturer list. All else remains the same. Modification #1 - Add Appendix J Optional Site Visit Information document. All else remains the same. The State of Colorado Department of Public Health and Environment, CDPHE, is soliciting bids from qualified contractors for the Replacement Air Compressors at the Argo WTF project. The two air compressors and compressed air storage system at the Argo WTF supply air to the reaction tank to assist in treatment of acid mine drainage from the Argo Tunnel in Idaho Springs, Colorado. The facility operates 24/7 and treatment will continue during construction. Occasional shutdown of the treatment is acceptable for startup of the new equipment. The single point is Kristi Gamble.
