Process Control Plan for the Silo 3 Project
Document No. 40430-PL-0003, Rev. 1
Jacobs Project Number 35H19605
September 5, 2003
This Process Control Plan (PCP) addresses the instrumentation and control logic for
equipment used in the Silo 3 Project at the U.S. Department of Energy Fernald
Environmental Management Project (FEMP) site. As part of the remediation of Operable
Unit 4 at the FEMP, approximately 5,100 yd3 of byproduct metal oxide materials stored in
Silo 3 will be removed, conditioned, packaged, and transported to an off-site facility for I
treatment and/or disposal.
Two other documents are frequently referenced in the PCP. These are Process Descrr;Otion
fur the Silo 3 Project (PD) (FEMP 2003a), which discusses the Silo 3 process systems and I
equipment, and Access and Retrieval Strategy for the Silo 3 Project (A&RS)
(FEMP 2002a), which describes the strategies used to remove material from Silo 3. The I
A&RS also describes the history of generation of Silo 3 material and its quantity and
characteristics (A&RS, Section 1.4).
This PCP provides, on a system-by-system basis, descriptions of the following:
0 Control philosophy
Interlocks
0 Setpoints and responses

SYSTEM NAMES AND NUMBERS
The systems addressed in this PCP and the relevant section numbers are shown in
Table 1-1: The same system names and numbers are also used in the Design Basis and
Requirements Document (FEMP 2002b).
1.2 NON-SYSTEM NAMES AND NUMBERS
Numbering systems for equipment, lines, valves, and instruments are defined in Project
Procedure FF-103-01 (Jacobs Engineering 2002). These systems are described in the
following sections:
1.2. I Equipment Numbering
The equipment numbering system is as follows:
XXXJJ-UZZ
Where:
0 XXX represents the Equipment Designator (see Table 1-2).
0 JJ represents the System Number (see Table 1-1).
0 ZZZZ represents the Equipment Sequence Number. For Silo 3, this is in the range
5000-6999.
All Silo 3 equipment numbers are provided in Silo 3 Project Equipment List (FEMP 2003b).
