DM To describe the general method of documenting changes or deviations to specified design / construction requirements by authorized field personnel 'ollowing relea.3e of engineering &cuments approved for fabrication or construction. Rese provisions are established to assure cu:pliance with the requirements of Reference 1-A. Note, supplemental engineering procedures / instructions may be used to describe and implement alternate methods of design cnange control.
2.2 SCOPE Design change / deviations shall be approved den complete and validated y designated authorities as des:ribed in this instruction.
2.3 RESPCESIBILITIES n e Assistant Project General Manager has overall responsibility for the design of the CPSES project. Authority for the implementation of this procedure has been delegated to the Manager of Engineering and subordinate engineering organizations. Further delegation of authority may be acconplished through formal engineering instructions supplementing this procedure.
ne Manager of Ehgineering shall assure that adequate tracking mechanisne exist to provide positive control of the issue, disposition, and status of cbcuments issued as a result of these measures.
2.4 DEFINITIONS ,
2.4.1- Engineerino Documents As used in this procedure, documents approved for fabrication or construction which specify design, engineering, and/or construction requirements (such as specifications and drawings).

. CP-EP-4.'6 10 4-16-84 2 of 15 2.4.2 Design Change A revision to engineering documents which affects the form, fit, or function of the affected structure, system or exponent.
2.4.3 Deviation A departure from a specified engineering requirement that &es not affect the form, fit, or function of affected structure, system, or conponent.
2.4.4 Engineering Change Requests A document used to forward engineering, design, or technical informa-tion between engineerire organizations for the purposes of initiating revisions to engineering documents. 'Ihe ECR is a connunication/
interface document which does not authorize fabrication or construction activities.
2.5 DOCCM arATION Design changes / deviations to specified engineering documents shall be documented by revision initiated by an Ergineering Change Regaest (ECR), a Design Change Authorization (DCA), or a Congonent Modification Card -(CMC). 'Ihe respective forms and the application of each are further described below.
3.0 PPOCEEURE 3.1 ENGINEERING GANGE REQUESTS 3.1.1 General EER's shall be used by CPPE to initiate design changes to be documented by document revision. In addition, design change proposals forwarded by other organizations such as Westinghouse Field Oiange Notices (PCN's), 'IUGCD Design Change Requests ('IDCR's) and Gibbs & Hill Design / Engineering Change / Deviations (DE/CD's) may be processed by ECR's.
Upon coupletion by the originator,the ECR shall be forwarded as specified herein for engineering h==nt incorporation, approval, and design verification as required.
3.1.2 Specif Scope of ECR's
'Ihe specific scope of changes (i.e., systems, subsystems, areas, engineerity documents, etc.) to be processed by ECR's shall be administratively defined by the CPP Digineering Manager.
WrE: . Changes critica"l to construction in terms of an Lwediate need for implementation may be exempted from the scope of ECR's on a case by case basis. Changes processed in this manner shall be &cumented by DCA/ CMC;' however, the change shall be authorized by specified engineering management personnel.

1 Design changes / deviations shall be verified either prior to, or after inplementation by authorized personnel, to confirm or substantiate that the change is acceptable from an engineering standpoint and consistent with the design basis (or input), ESAR comnitments and applicable codes and standards. 'Ihis verification shall normally be acccmplished by the original design organization in accordance with established procedures although the provisions of References 1-B or 1-E may be utilized at the discretion of the Assistant Project General Manager.
l In the event the design verification a~ctivities indicate the change / deviation is unacceptable, the reviewing agency shall notify the originating organization who may, on the area in question, place a " Hold" or rescind and reissue the change /
deviation. Any physical corrective action required in problem areas shall be evaluated and formulated on a case by case basis.
3.2.6 MterfaceControl Significant changes / deviations to engineered items involving A/E and vendor interfaces for equipnent foundaticn details shall be reviewed with both the A/E and the vendor for cxxnpliance with design reqdirements, prior to approval for fabrication or construction.
Formal cbcumentation where vendor or A/E approval is required shall be accomplished in accordance with Reference 1-C.

- 3. FOR PIPING ONLY AND INTEGRAL HANGER ATTACHMDTTS - If, after the original issue of BRP drawing, a weld has to be removed and rewelded, the weld number will be changed to indicate same by adding an "A" for the first removal, "B" for the second removal, etc. to the weld nu:rbers, e.g.,
for the weld 6, the first removal / reweld is 6A, and if 6A requires rework, the second removal / reweld is 68.
- 4. FOR PIPING 0;I.ll - When stainless steel materials are re-used and tne heat affected zone not removed, the new weld number will include the next sequential letter of the item with the highest numerical weld nu cer.
For exanple, if the pipe between welds 7A and 6C is deleted, and the remaining parts welded together, the new weld number will be 8D, not 7B. In the situation where weld 6A is cut and a pup installed between the tw pieces, the new welds will t:e numbered 6B and 6A-1.
- 5.
