The <br /> generator room provides containment for the generator. However, <br /> penetrations are present on the floor of the generator room. It is <br /> recommended that these penetrations be sealed. <br /> 0 2) Fluids from the platform area drain to a sump located under the <br /> 0 platform and then to platform runoff tanks DW-303 and DW-304. <br /> � <br /> Additionally, fluids from the compressor area also gravity drain to <br /> platform water runoff tanks DW-303 and DW-304. It is recommended <br /> -d that written procedures to inspect and drain the sump and compressor <br /> N <br /> 0 area containment on a regular basis be prepared and implemented. <br /> 0� Additionally, a written procedure to remove water from tanks DW-303 <br /> and DW-304 on a regular basis should be prepared and implemented. <br /> Records of inspection and maintenance activities should be completed <br /> and maintained.
