Project W-030 has implemented BAT/AKART will be in the scope of Project W-252. This will be accomplished by utilizing existing B-Pond piping, and the TEDF Tie-in. (Subject to funding restrictions identified in the Introduction.)

Project W-252 will provide the facilities and equipment to collect, sample, monitor, and transport to TEOF for disposal the effluent from E-Plant. addition the project will collect and transfer to TEDF the remaining Phase I1 streams by a single downstream connection. (Subject to funding restrictions identified in the Introduction.) interface of those streams will be done by others, except for pump interface signals.

The project will include the necessary utilities, communications, fire protection, and other safety-related items or features to make the project operational. In addition, these utilities will be designed to allow this project to be integrated with the 200 Area TEDF. provided by the project where necessary to construct, maintain, or operate the provided systems.

5.7 DECONTAHINATION AND DECOMMISSIONING

The design will incorporate ease of decontamination and decommissioning of all project systems, in accordance with DOE Order 6430.1A and other referenced standards. The project shall minimize the buildup of residual contamination by avoiding practices (such as socket weld fittings) which promote accumulation of contamination irl piping or equipment. All equipment and components provided by the project shall be designed to facilitate eventual decontamination and decommissioning. All underground piping removed from service by this project shall be isolated in an environmentally acceptable manner.

5.8 OPERATING PERSONNEL AND SERVICES

The design will consider human factors for maintenance and operations activities, including equipment, valve location and orientation, secondary waste handling, and building layout. To the extent practical, design will follow the guidelines and standards of DOE Order 6430.1A, 1300-12, NUREG 0700, Mil-STD 14721) and WHC-SD-GN-DGS-30011, "Radiological Design."

o Rapid, safe, economical operations and maintenance.

o Anthropometric design for male and female personnel.

o Minimal distraction, discomfort, stress, and fatigue during operations and maintenance.

The completed project will, to the extent possible, accommodate physical limitations such as hearing impairment and color blindness. instruments, etc., shall be placed in accordance with the human factors requirements of the referenced standards.

Gauges,

5.9 COMMUNICATIONS AND TELECOMMUNICATIONS SYSTEMS

Radio station communications, telephones, and extensions to the private automatic exchange (PAX) associated with each facility shall be provided, as required to support the functional requirements of the project. Telephones will be installed in the occupied work areas to permit communications within the new facilities and with other area facilities. The number of telephones installed will be determined in the definitive design. Crash alarm phones,

6.0 CODES AND STANDARDS

The project will be designed to handle low-level radioactive wastestreams which are below the requirements of secondary containment found in DOE Order 5820.2A. applicable provisions of DOE Order 6430.1A and DOE Order 5400.1.

Design criteria for Project W-252 are to be based upon the

The following list identifies the appropriate codes, standards, regulations, guidelines, orders, etc., which are not defined within DOE Order 6430.1A. Revisions to the codes and standards during the project shall be administered by the project, with assessments prepared to identify the impact of these revisions. project specific requirements and procedures.

Utilize the codes and standards established for the 200 Area TEDF for interconnecting piping and instrumentation and as much as possible for all other comparable equipment.

Impacts shall be managed in accordance with DOE, contractor, and
