NOTE

The requirements of paragraph 3.1 (General) applies to all work under the scope of this contract, whether explicitly stated in work items or not, and also to all other work subsequently authorized by changes, modifications, or extensions to the contract.

3.2 Contractor-provided fire watch personnel. The Contractor shall provide fire watch personnel and equipment.

3.3 Welding and brazing requirements. The Contractor shall perform all welding and allied processes, and NDI in accordance with SFLC Std Spec 0740.

3.4 HW disposal. The Contractor is considered as the generator of all contract-generated hazardous wastes and shall use its facility‟s EPA generator ID number for management, transportation, and disposal of said hazardous wastes. Ensure the following:

3.4.1 Contractor‟s hazardous waste handlers shall comply with applicable requirements of 40 CFR 262.

3.4.2 All contract generated hazardous wastes shall be packaged in 49 CFR-compliant containers.

3.4.3 The designated wastes shall be disposed of at a state or Federally-approved and permitted HW TSDF.

3.4.4 Name of destination TSDF shall be submitted to the KO at the Arrival Conference.

3.5 Interim changes and additions to SFLC Std Spec 0000. The Contractor shall be aware of the following interim changes and additions to the 2009 Edition of SFLC Std Spec 0000:

3.5.1 Acronyms and term definitions – paragraph 1.3 (Acronym and term definitions).

3.5.1.1 The term “COTR” has been replaced with “COR”, which is defined as follows:

“COR”: Contracting Officer‟s Representative – the person delegated by the KO as the on-scene representative for matters concerning performance of work; this includes correctness, timeliness, and quality of the Contractor‟s work. Normally, the CO/OINC is designated the COR.”

3.5.1.2 Definition addition for the term “Ungrounded, as follows:

“Ungrounded”: A power system where all of the current-carrying conductors and windings

(including any neutral connection) are insulated from ground. In contrast, a generator or transformer in which at least one conductor or point (usually the midpoint or corner of a delta winding or the common center of a wye winding) is intentionally grounded, either solidly or through an impedance, is considered grounded. Note that the distinction concerns only current-carrying conductors; for both ungrounded and grounded power systems, non-current carrying metal parts and equipment grounding conductors are always bonded to earth ground for personnel safety. At non-Governmental facilities, dockside wye connected transformer secondary windings are almost always grounded and are generally not suitable for connection to a Coast Guard cutter without a separate Contractor furnished

3 (Rev-0) isolation transformer.”

3.5.2 Changes to paragraph 3.2.4 2.3 (QP-1 Inspector or Tech Rep duties).

“3.2.4.2.3 QP 1 Inspector or Tech Rep duties.
