David Harvey President .T mbl. Page 3 of 12 2.0 PROCEDURES FOR PERFORMING SERVICES .Tomtiw 2.1 METHOD OF APPROACH Scope of Work: The inspection of each tank will include the extent of coating and materials deterioration, area by area within each structure. The principle areas of consideration are the roof, the exterior wall and appurtenances, the interior underside of the roof and supporting columns and the non -immersed areas of the interior wall and appurtenances. To perform a complete inspection of the floor, cleaning of the sediment accumulation up to l" in depth from the tank floor is highly recommended. Video documentation of the floor will be obtained prior to cleaning, which will indicate the amount of silt and sediment present. During the time of inspection, Water i personnel shall raise and maintain water level to near overflow. This allows the divers headroom, yet enables easy access to document the interior roof, columns, etc. Interior inspection, both over and underwater, will be conducted to determine coating condition of the tanks' interior walls, roof beams, columns, ladder, interior coating, depth monitoring equipment, cathodic protection equipment, etc. Tank interior air sampling shall be performed and PDI confined space entry permit(s) will be completed prior to diver entry to the tank. Diver(s) shall be decontaminated per ANSI/AWWA C652-02 prior to entry. A hi -resolution color video camera will be attached to the divers helmet and monitored at the surface dive station by the dive supervisor and, if desired, by representatives of the Water company. Direct communications with the diver will be maintained at all times. Potable Divers Inc will offer the color still -photographs and video. Accordingly, information will be documented using a flash memory card other formats are available at the Clients' option. A typed report will be generated on the team's findings referencing video related inspection information to location diagrams and an inspection overview. The report will include the existing condition of the interior and exterior of each reservoir and provide recommendations for repairs, if necessary and an evaluation of ongoing maintenance needs. Safety Program: Included for your review is a very brief summary of our safety policies and practices manual, this is due to the size and volume of the 300 plus page manual. A complete manual is available at each job site for the clients review. The Policy of Potable Divers Inc, herein after called the "Company", is to maintain the highest standards for the Safety and Health of all the Company employees and to conduct all activities with appropriate safeguards against exposure of the general public to risks against their safety and health. In order to meet this criterion the Company. provides and maintains safe and healthy working conditions, equipment, and safe systems of work for all its employees, and to provide such information, training, and supervision, as they need for this purpose. Page 4 of 12 The Company accepts its obligations to seek to reduce the incidence of accidents, dangerous occurrences and hazards to the safety and health :of its employees and other people who may be affected by our activities. The Company requires that all employees shall regard safe working as a prime objective and take all possible steps to achieve it. Safety is the condition for the protection of life, property, and/or equipment against failure, breakage, or accidental loss. To aid in achieving this objective, every person involved must realize the potential consequences of accidents and comply fully with the Company Safety Procedures and applicable legislation. In putting this Safety Policy into practice, the Safety Group is authorized to require the cessation of work where they deem Safety to have been compromised. Potable Divers Inc is totally committed to SAFETY; it is the primary priority of the Company and shall not be compromised. The management and staff, of the Company have adopted a "multi-faceted approach" to safety management in order to provide and ;maintain a safe and healthy working environment on all operations, while ensuring the objectives of the operation are achieved efficiently and with a minimum of risk to personnel. In order to implement these goals, various policies, procedures, and guidance are promulgated in Company manuals. It is the intent that the Diving Operations Manuals will provide Codes of Practice for all Potable Divers Inc diving operations and it is a mandatory requirement that all personnel involved with diving operations familiarize themselves with the instructions contained therein. Where National or Local Government legislation exists applicable to diving operations, it is intended that the procedures and practices quoted in the Diving Operations Manual will take precedence to the Government legislation, only in circumstances where the company policy is more stringent. The wide scope of diving operations and variety of equipment used inevitably means those specific instructions for every situation and circumstance is not possible. These instructions, however, form the basis from which every operation will develop its individual procedures applicable to that operation. Supervisors are directly responsible for the implementation of these policies and are to ensure that no unjustified deviations occur. All personnel working on Potable Divers Inc diving operations will, in addition to any statutory obligation, comply with these policies except where authorized dispensation has been given. No person may willfully, or without reasonable cause, do anything liable to endanger the safety of themselves, other personnel, plant, or equipment. Diving is a potentially hazardous occupation, which requires constant alertness, discipline, and dedication to ensure the safety of all concerned. c:Pomhfc otayWD Page 5 of 12 [ THINK SAFE ] [ WORK SAFE ] [ BE SAFE ] Any persons discovering a hazard or equipment malfunction at their work place must report the fact immediately to their supervisor, who will report it to the Safety Department if necessary. 2.2 DOCUMENTATION OF STORAGE TANKS, PROPERTY, AND CATHODIC PROTECTION All findings found are documented before, after, and during cleaning and inspection on the video report as well as still photos. Items to be documented will be any area of concern, corrosion, holidays, cracking, blistering, pitting, inconsistency, all tank/reservoir plumbing, fittings, joints, seams, columns, panels, interior coating, floor plates/bases and so forth. A video in a format chosen by the client i.e. DVD, flash memory, will be provided as part of the report along with still photos, and a computer generated report of all findings. Video and audio will be live while the diver is in the water this is for the divers' safety as well as the clients' convenience. Video camera is mounted to the divers' helmet, to provide uninterrupted video for the topside personnel. The video camera has high resolution and fixed focus technology with lighting. Inspection will begin at the 12:00 o'clock position and will proceed with the inspection in a clockwise manner. 3.0 EQUIPMENT 3.1 VACUUM -CLEANING HEAD OtayWD For the last few years Potable Divers Inc. has put a lot of time and research into our underwater vacuum system, saving our clients more time, water, and money. Our system being made of glass gives us several unique capabilities, glass can be decontaminated more efficiently than a porous metal, glass also allows our clients and our divers to observe both inside and outside the vacuum system, thus assuring the floor is completely cleaned during the "scrubbing" process with the brush. The "scrubbing" process is the most critical part of the cleaning, as experience has proven the vacuum system must be able to provide adequate power for the scrubbing process. Suction driven and in some cases motor driven vacuum heads do not provide adequate power when introduced to heavier sediments such as mud, sand, or clay. Even small amounts of silt and small debris (such as rocks) can cause the brush to slow down not providing the vigorous scrubbing needed to remove the bacteria bio film that lives under the sediment. Potable Divers' proprietary vacuum has the capability to be controlled by the diver and/or top side personnel to increase the power of the vacuum -cleaning head. To make sure the brushing is adequate, it is observed through the glass housing by our divers as well as our clients, and can be adjusted accordingly. The brush can be controlled to revolve from 50 revolutions per minute to 5000 revolutions per minute. The proprietary vacuum system was designed to create no turbidity, as all sediment is enclosed in the glass housing and removed with high power suction as it is vigorously brushed.
