The OIP was submitted to the NRC on February 28, 2013. The first six-month updatewas submitted to the NRC on August 20, 2013 (Reference 2). The second six-month update wassubmitted to the NRC on February 28, 2014 (Reference 3). The third six-month update wassubmitted to the NRC on August 28, 2014 (Reference 4). The fourth six-month update wassubmitted to the NRC on February 27, 2015 (Reference 5). The fifth six-month update wassubmitted to the NRC on August 26, 2015 (Reference 6). This enclosure provides an update ofmilestone accomplishments including any changes to the compliance method, schedule, or needfor relief/relaxation and the basis, if any, that occurred during the period between July 28, 2015,and January 28, 2016, hereafter referred to as the update period.

These changes do not impact BSEP's compliancewith NEI 12-06.1) Chan~qe: One of two raw water supply methods for Condensate Storage Tank (CST) refill(i.e., water trucks and portable tanks) is removed from the OST fill strategy. The dischargecanal water supply is maintained as the raw water supply for the water makeup strategy.Reference 5 provided the initial long term makeup water strategy.Justification:CST refill uses on-site clean water sources that survive the Beyond Design Basis ExternalEvent (BDBEE) before using raw water. During development of the CST refill strategy, thesite established the "discharge canal" and "water trucks and portable tanks" as raw watersources. The "water trucks and portable tanks" water source, which relies upon a privateoff-site company to truck water to the site, may not be a reliable source following a BDBEE.BSEP has the resources (i.e., personnel, equipment, and procedures) to supply water to theCSTs from the plant discharge canal (i.e., an indefinite supply of water) following a BDBEE.BSEP has implemented the BWROG-TP-14-006 guidance for use of raw water into theReactor Vessel Control Procedure Emergency Operating Procedure. Compliance withNEI 12-06 is not impacted.Documentation:1. 0EOP-01 -FSG-1 5, Unit 2 FLEX Condensate Storage Tank Fill2. 1/2EOP-01-RVCP, Reactor Vessel Control3.

These changes do not impact BSEP's compliancewith NEI 12-06.1) Chan~qe: One of two raw water supply methods for Condensate Storage Tank (CST) refill(i.e., water trucks and portable tanks) is removed from the OST fill strategy. The dischargecanal water supply is maintained as the raw water supply for the water makeup strategy.Reference 5 provided the initial long term makeup water strategy.Justification:CST refill uses on-site clean water sources that survive the Beyond Design Basis ExternalEvent (BDBEE) before using raw water. During development of the CST refill strategy, thesite established the "discharge canal" and "water trucks and portable tanks" as raw watersources. The "water trucks and portable tanks" water source, which relies upon a privateoff-site company to truck water to the site, may not be a reliable source following a BDBEE.BSEP has the resources (i.e., personnel, equipment, and procedures) to supply water to theCSTs from the plant discharge canal (i.e., an indefinite supply of water) following a BDBEE.BSEP has implemented the BWROG-TP-14-006 guidance for use of raw water into theReactor Vessel Control Procedure Emergency Operating Procedure. Compliance withNEI 12-06 is not impacted.Documentation:1. 0EOP-01 -FSG-1 5, Unit 2 FLEX Condensate Storage Tank Fill2. 1/2EOP-01-RVCP, Reactor Vessel Control3.
