WASHINGTON (AP) - The Environmental Protection Agency has decided there’s no need to rid drinking water of a toxic rocket fuel ingredient that has fouled public water supplies around the country.
EPA reached the conclusion in a draft regulatory document not yet made public but reviewed Monday by The Associated Press.
The ingredient, perchlorate, has been found in at least 395 sites in 35 states at levels high enough to interfere with thyroid function and pose developmental health risks, particularly for babies and fetuses, according to some scientists.
The EPA document says that mandating a clean-up level for perchlorate would not result in a “meaningful opportunity for health risk reduction for persons served by public-water systems.”
The conclusion, which caps years of dispute over the issue, was denounced by Democrats and environmentalists who accused EPA of caving to pressure from the Pentagon.
RAISED BORE METHOD - 8.2.1.7. New Shaft Chamber and Tunnel, pp. 11-12
“. . . the raised bored construction method . . . involves drilling of a pilot hole from the surface. A boring drill rig would be assembled at the bottom of the shaft where the tunnel would terminate, and turned by a machine at the top. The boring spoils would fall into the tunnel, and would be removed as the drill is raised from the bottom of the shaft. Using the new tunnel for access, all the debris would collapse into the new tunnel and would be removed at the water treatment plant site . . . . This method would reduce the impact caused by construction in the area.”
(1) no surface drilling or blasting
(2) hoe ram drilling
(3) blasting

This is the exact presentation given to the Facilities Monitoring Committee five days before the presentation at Amalgamated. Clearly you can see the DEP making the case between two types of methods, but not the one they have permission to use. The EIS is clear: no surface drilling (and that includes hoe rams) or blasting.

Community Boards 7, 8 and 12 will hold a meetingto hear from the public on whether or not the New York City Department of Environmental Protection can or should using blasting in work they propose to do in and around the Jerome Park Reservoir.
Tuesday, July 15, from 6:30 p.m. to 8:30 p.m.
Lehman College’s Music Building, Faculty Dining Room
250 Bedford Park Boulevard West, at Paul Avenue and Bedford Park Blvd
The Final Environmental Impact Statement (issued by then DEP Commissioner Chris Ward in 2004) stated that they would be no impacts at the Jerome Park Reservoir based on the work method proposed. Now they want to switch in mid-stream. If they want to do this, they will have to do a supplemental study. The trucks associated with the blasting method will be driving through our streets!
