Petroleum Development Oman Estate Services Asset Environmental Assessment 2002 Review and Update The green waste generated is disposed along with the domestic garbage in the municipal landfill. 3.3.11 Miscellaneous Services The services provided by estate services also include the maintenance of the training centre, where a model of the Hibah gathering station is kept as a simulator. This is an electrically operated and self-contained unit. This unit undergoes regular, preventative maintenance as per the requirements of the training department. Estate services are also responsible for the providing the necessary building maintenance services for the PDO school. Estate services also provide and maintain the fire fighting system in MAF and RAH areas. Portable fire extinguishers are accessible at all areas with potential fire hazards. The extinguishers are of several types including pressurised water, dry foam, and carbon dioxide. Consequent to PDO’s policy of phasing out ozone depleting substances, estate services have replaced all of the halon-containing substances commonly used in hand-held fire extinguishing apparatus. A service contractor handles the general servicing and maintenance of portable fire extinguishers in the areas managed by estate services. The Estate Services also look after traffic wardening in the MAF area. PDO does not own any fleet for the transport of materials and men in and out of its coastal asset areas. All the necessary fleet are supplied and maintained by the various contractors. 3.4 Materials and Utilities The estate services asset is not a direct consumer of materials and utilities, since the contractors perform almost all of its operational activities. ©HMR Environmental Engineering Consultants C 3- 12 Oman’s Environmental Consultancy HMR\1501\Estate Services
Petroleum Development Oman Estate Services Asset Environmental Assessment 2002 Review and Update 4 RELEASES TO ENVIRONMENT 4.1 Introduction In this section, the various waste products released into the environment as a result of the operational activities of the estate services asset are discussed. As discussed in Chapter 3, the estate services staff do not directly perform any operational activities. Instead, approved contractors perform these activities under the supervision of estate services staff. The major activities of the asset include building maintenance; air-conditioning maintenance; electrical power supply; potable water supply; catering and laundering; recreational facilities maintenance; sewage treatment and disposal; solid waste collection and disposal; roads and parks maintenance; and other miscellaneous services. The wastes resulting from the above activities and released into the environment may be classified into the following groups, based on their physical state as well as nature: - Air emissions - Liquid effluents - Solid wastes - Noise - Accidental leaks and spills In order to quantify and characterize these releases, the currently available database is used. In cases where data are not available or insufficient, an attempt is made to estimate the quantities and characteristics using theoretical or empirical equations. 4.2 Air Emissions 4.2.1 Sources of Generation Air emissions sources may be classified as point sources, area sources and mobile sources. The point sources include the stacks and vents. The area sources include the open tanks and open pits for storage of materials with volatile components. The mobile sources include the passenger cars, transport vehicles and engines used for construction equipment. In the areas serviced by estate services, there are no continuous point sources of air emissions. The only stacks are those attached to the DGs and the incinerator.
