It should be provided with a control system that should be such that the services needed for the proper operation of the Ballast Water Treatment Equipment are ensured through the necessary automatic arrangements.
 
4.9 The Ballast Water Treatment Equipment should, if intended to be fitted in locations where flammable atmospheres may be present, comply with the relevant safety regulations for such spaces. Any electrical equipment that is part of the BWMS should be based in a non-hazardous area, or should be certified by the Administration as safe for use in a hazardous area. Any moving pails, which are fitted in hazardous areas, should be arranged so as to avoid the formation of static electricity.
 
Control and Monitoring Equipment
 
4.10 The BWMS should incorporate Control Equipment that automatically monitors and adjusts necessary treatment dosages or intensities or other aspects of the BWMS of the vessel, which while not directly effecting treatment are nonetheless required for proper administration of the necessary treatment.
 
4.11 The Control Equipment should incorporate a continuous self-monitoring function during the period in which the BWMS is in operation.
 
4.12 The Monitoring Equipment should record the proper functioning or failure of the BWMS.
 
4.13 To facilitate compliance with Regulation B-2, the Control Equipment should also be able to store data for at least 24 months, and should be able to display or print a record for official inspections as required. In the event the Control Equipment is replaced, means should be provided to ensure the data recorded prior to replacement remains available on board for 24 months.
 
4.14 It is recommended that simple means be provided aboard ship to check on drift by measuring devices that are part of the Control Equipment, repeatability of the Control Equipment devices, and the ability to re-zero the Control Equipment meters.
 
5 TYPICAL DOCUMENT REQUIREMENTS FOR THE PLAN APPROVAL PROCESS
5.1 The documentation submitted for approval should include at least the following:
 
.1 a description of the BWMS. The description should include a diagrammatic drawing of the typical or required pumping and piping arrangements, and sampling facilities, identifying the operational outlets for treated ballast water and any waste streams as appropriate and necessary. Special considerations may have to be given to installations intended for ships that have unusual pumping and piping arrangements;
 
.2 equipment manuals, supplied by manufacturers, containing details of the major components of the BWMS and their operation and maintenance;
 
.3 a generic operations and technical manual for the complete BWMS. This manual should cover the arrangements, the operation and maintenance of the BWMS as a whole and should specifically describe parts of the BWMS which are not covered by the manufacturer' s equipment manuals;
 
.4 the operations section of the manual including normal operational procedures and procedures for the discharge of untreated water in the event of malfunction of the Ballast Water Treatment Equipment. maintenance procedures, and emergency action necessary for securing the ship;
 
.5 methods for the conditioning of treated water prior to discharge should be provided, and assessment of discharged water should include a description of the effect of treatment on the ship's ballast water, in particular the nature of any treatment residuals and by-products and the water's suitability for discharge into coastal waters. A description should also be provided of any actions necessary to monitor, and if necessary "condition", treated water prior to discharge in order that it meets applicable water quality regulations;
 
.6 a description of BWMS side streams (e.g., filtered material, centrifugal concentrate, waste or residual chemicals) including a description of the actions planned to properly manage and dispose of such wastes;
 
.7 a technical section of the manual including adequate information (description and diagrammatic drawings of the monitoring system and electrical/electronic wiring diagrams) to enable faultfinding. This section should include instructions for keeping a maintenance record;
 
.8 a technical installation specification defining, inter alia, requirements for the location and mounting of components, arrangements for maintaining the integrity of the boundary between safe and hazardous spaces and the arrangement of the sample piping; and
