VYNPS BASES: 4.10 (Cont'd)

C. Logging the diesel fuel supply weekly and after each operation assures that the minimum fuel supply requirements will be maintained. During the monthly test for quality of the diesel fuel oil, the tests specified in Table 1 of ASTM D975-93 will be performed. The quality of the diesel fuel oil will be acceptable if the results of the tests are within the limiting requirements for diesel fuel oil shown on Table 1 of ASm D975-93. Cloud point shall be less than the 10th percentile minimum temperatures for Vermont Yankee which have been determined from over 15 years of site-specific meteorological data using the method specified in Appendix X3 of ASTM D975-93.
