l Removal of accumulated water as required by 4.8.1.1.2.b.2 is performed by drawing the contents off the bottom of the tank until acceptable results are obtained for either a tape test or a water and sediment test. An acceptable result for the water and sediment content is a measured value less than 0.05 percenLvolume.

.The sample specified in 4.8.1.1.2.c.4 is sent offsite for testing. A serious attempt will be made to meet the 31-day limit on the offsite tests; however, if for :,ome reason this limit is not met (e.g., if the sample is lost or broken or if the results are not received in 31 days), the diesel generators should not be considered inoperable. If the sample is lost, broken, or fails the offsite tests and the new oil has already been put into the storage tank, the offsite tests will_be performed on a sample taken from the storage tank. If the results on the subsequent storage tank sample are not within specified limits,'the diesel -

generators,should be considered OPERABLE and the out-of-spec properties should be returned to within specification as soon as possible.

If the monthly, storage tank sample taken in accordance with Specification 4.8.1.1.2.d da11s the particulate contamination test, the diesel generators should 10 below be mg/

considered liter as OPERABLE and the contamination level should be restored to soon as possible.

The precision leak-detection test described in Surveillance Requirement 4.8.1.1.2.f.2 should be performed as described in NFPA (National Fire Protection Association) -329.

BASES Removal of accumulated water as required by 4.8.1.1.2.b.2 is performed by drawing the contents off the bottom of the tank until acceptable results are obtained for either a tape test or a water and sediment test. An acceptable result for the water and sediment content is a measured value less than 0.05 percent vcMume.

The sample specified in 4.8.1.1.2.c.4 is sent offsite for testing. A serious l attempt will be made to meet the 31-day limit on the offsite tests; however, if for some reason this limit is not met (e.g., if the sample is lost or broken or if the results are not received in 31 days), the diesel generators should not be considered inoperable. If the sample is lost, broken, or fails the offsite tests (

and the new oil has already been put into the storage tank, the offsite tests will be performed on a sample taken from the storage tank. If the results on the q l

subsequent storage tank sample are not within specified limits, the diesel- .

generators ,should be considered OPERABLE and the out-of-spec pro,pertier should be l returned to within specification as soon as possible.

If the monthly storage tank sample taken in accordance with Specification 4.8.1.1.2.d' falls the particulate contamination test, the diesel generators should10 below bemg/ considered OPERABLE liter as soon and the contamination level should be restored to as possible. -

The precision leak-detection test described in Surveillance Requirement 4.8.1.1.2.f 2 should be performed as describpd in NFPA (National Fire Protection Association) -329. As NFPA-329 is revised, the precision leak-detection test may be modified to incorporate changes to the test as described in the revisions to NFPA-329. .
