The project consists of the following elements: 1) the Oxidation Retrofit Program (ORP), 2) the Weymouth Improvements Program, and 3) operation and maintenance activities. Metropolitan has funded and authorized final design of ozone facilities for the ORP. The addition of ozone at Metropolitan's treatment plants will remove blend restrictions and substantially lower disinfection by-product levels for compliance with both Stage 1 and Stage 2 of the Environmental Protection Agency's Disinfectants/Disinfection By-Products Rule. The ORP includes ozone generation equipment, site preparation, ozone facilities (including a liquid oxygen storage facility, ozone generation building, ozone contractor building, an ozone off-gas destruct system, electrical switchgear building and switchyard, chemical tank farms, hydraulic conduits, ancillary systems, and general site road improvements), chemical storage and feed systems, utility systems, and mofications to upstream hydraulic features. Upgrades to the Wheeler Avenue plant entrance will be made to enhance plant security and deliveries, a new rail spur will be constructed to allow for rail delivery of sodium hydroxide and sulfuric acid to the ORP area, and new power facilities will be built.
