Dear Mr. Nelson
The December 11 and 12, 1990, construction inspection
raised concern about the proposed battery areas at the Ray
Roberts and Lewisville hydroelectric Projects Nos. 3939 and
3940, respectively, awhile providing an "eye wash" area is
recognition of the hazard that batteries pose, that alone is
not adequate. Additional requirements are that battery fumss,
gases, and electrolytic spray should not be allowed to escape
ante other cress and must be vented directly outside. These ener and than UntS.aBureau oof Reclamatio enclosed guidance by osatA
Our review of the proposed battery spaces in the power-
houses has indicated changes in the design will be necessary
Such changes are discussed by project below
aeberta vreiect Ne Plans show that batter-
les grill be located in a niche in the powerhouse wall;
ventilation is by the powerhouse ventilation system While
batteries will in this instance be protected from failing
objects, gases may still be released into the powerhouse
Completely enclosing this area with a concrete block wall
should solve the enclosure problem; however, ventilation must
also be provided.
Lerieviii• s94o. Plans show the battery
racks located in a corner of the powerhouse with a grating
overhead. There are no walls around the area and ventilation
is by the plant ventilation system. With this configuration,
batteries are subject to damage from overhead Explosions or
fires in this area could release gases throughout the power-
house. This situation must be corrected by relocation of the
batteries or by enclosing the area and adding ventilation to
the outside
