Distribution - Various Locations Manhattan - On January 12, 2001 the discharge from the 40ih Street Pumping Station was revalved. The northwest regulator at Shaft 18 was also revalved. This work was done to compensate for the 48' inch water main in 7th Avenue, between 401h and 42nd Streets, which was out of service due to subway station construction. Capital projects for new water mains were initiated for the following:

- Improved water supply for Lower East Side of Manhattan in the vicinity of Stuyvestant Town - New building sites along 149th Avenue at Springfield Lane in Queens.

The Green Building, Battery Park City; Manhattan DEP staff has completed its review of the site connection proposal application filed by the Albanese Development Corporation and their consultant on behalf of the Battery Park City Authority for the `Green Building' project at Terrace and Murray Streets in Battery Park City.

Bypass Discovered near New Stadium Alerted by a contractor working at the new Yankee minor league stadium in the Saint George area of Staten Island, agency crews verified that there is a continuing dry-weather bypass of 5 to 10 GPM occurring at the PR-011 outfall. The outfall is located at Hamilton Avenue, and is discharging raw sewage into the Upper Bay. By January 9th, our investigations confirmed that at least one building, 185 St. Marks Place, had an illegal connection, and we were following up with monitoring and dye- testing on three other buildings that were suspected of being improperly connected. The bypass has been reported to NYSDEC, and to our own Division of Sewer Regulation and Control, which will direct the reconnection of all improperly connected buildings to the appropriate sanitary sewer.
