3.7.3.2 SFLC Std Spec 0000, page 3, bullet “ISC.” Delete “lead-contaminated materials.”
3.7.3.3 SFLC Std Spec 0000, page 27, after Note box under paragraph 3.3.13.1.2 add the following paragraphs:
3.3.13.1.3 Dock and Sea trials. The Contractor shall conduct dock trials to test the work performed during the contract when required by individual work items (see 3.3.13 Tests and Inspections). This shall include operational tests or inspections, as appropriate, of all machinery, piping, wiring, insulation, preservation work, deck coverings, and any other article removed, moved, disturbed, or damaged by the Contractor in accomplishing the work outlined in the specification. Schedule for these specific dockside tests or inspections shall be included within the planning document (see 3.2.5 Planning document).
3.3.13.1.3.1 The Contractor shall provide a pier facility or allow the vessel to move to a Coast Guard pier to support dock trials. The Contractor shall not conduct trials that require the vessel to be waterborne while the vessel is floating inside a dock (e.g., graving dock, floating drydock).

Preconstruction primers may be left in place in other interior areas (such as machinery spaces, habitability spaces, etc.) if they are intact, uncontaminated, and compatible with the overcoating system.”
3.7.4.1 Std Spec 6310, Appendix B, page B12 , the formatting for of Notes 17-19 change and add as per the following:
SFLC Std Spec 6310, Cutter And Boat Interior Painting Systems, Appendix B12, Note 17, delete sentence, “Persistent corrosion in a particular area of an aluminum bilge may dictate the need for a protective High Build Epoxy coating to be applied to that local area.”

NOTE
The following inspections are for determining the existing condition of the coating system for the underwater body surfaces, which are deemed “Critical-coated” surfaces; they must be carried out by a SSPC-QP-1 certified contractor/sub-Contractor or a NACE Inspector – see SFLC Std Spec 0000, paragraph 3.2.4.2 (In-process QC measures for “critical-coated surfaces”).
3.2.7.1 Visual. Perform a visual inspection of the existing U/W body coating system.
