1、Environmental Guidance Document: Waste Management in Exploration and Production Operations API E5 SECOND EDITION, FEBRUARY 1997 Strategies for Todays Environmental Partnership American Petroleum Institute One of the most significant long-term trends affecting the future vitality of the petroleum ind
2、ustry is the publics concerns about the environment. Recognizing this trend, API mem- ber companies have developed a positive, forward looking strategy called STEP: Strategies for Todays Environmental Partnership. This program aims to address public concerns by improving industrys environmental, hea
3、lth and safety performance; documenting perfor- mance improvements; and communicating them to the public. The foundation of STEP is the API Environmental Mission and Guiding Environmental Principles. API standards, by promoting the use of sound engineering and operational practices, are an important
4、 means of implementing APIs STEP program. API ENVIRONMENTAL MISSION AND GUIDING ENVIRONMENTAL PRINCIPLES The members of the American Petroleum Institute are dedicated to continuous efforts to improve the compatibility of our operations with the environment while economically de- veloping energy reso
5、urces and supplying high quality products and services to consumers. The members recognize the importance of efficiently meeting societys needs and our re- sponsibility to work with the public, the government, and others to develop and to use nat- ural resources in an environmentally sound manner wh
6、ile protecting the health and safety of our employees and the public. To meet these responsibilities, API members pledge to manage our businesses according to these principles: 0 To recognize and to respond to community concerns about our raw materials, prod- ucts and operations. o To operate our pl
7、ants and facilities, and to handle our raw materials and products in a manner that protects the environment, and the safety and health of our employees and the public. o To make safety, health and environmental considerations a priority in our planning, and our development of new products and proces
8、ses. o To advise promptly appropriate officials, employees, customers and the public of in- formation on significant industry-related safety, health and environmental hazards, and to recommend protective measures. o To counsel customers, transporters and others in the safe use, transportation and di
9、s- posal of our raw materials, products and waste materials. o To economically develop and produce natural resources and to conserve those re- sources by using energy efficiently. o To extend knowledge by conducting or supporting research on the safety, health and environmental effects of our raw ma
10、terials, products, processes and waste materials. 0 To commit to reduce overall emissions and waste generation. o To work with others to resolve problems created by handling and disposal of haz- ardous substances from our operations. o To participate with government and others in creating responsibl
11、e laws, regulations and standards to safeguard the community, workplace and environment. 0 To promote these principles and practices by sharing experiences and offering assis- tance to others who produce, handle, use, transport or dispose of similar raw materi- als, petroleum products and wastes.

API is not undertaking to meet the duties of employers, manufacturers, or suppliers to warn and properly train and
14、equip their employees, and others exposed, concerning health and safety risks and precautions, nor undertaking their obligations under local, state, or fed- eral laws. Information concerning safety and health risks and proper precautions with respect to particular materials and conditions should be
15、obtained from the employer, the manufacturer or supplier of that material, or the material safety data sheet. Nothing contained in any API publication is to be construed as granting any right, by im- plication or otherwise, for the manufacture, sale, or use of any method, apparatus, or product cover
16、ed by letters patent. Neither should anything contained in the publication be construed as insuring anyone against liability for infringement of letters patent. Generally, API guidance documents are reviewed and revised, reaffirmed, or withdrawn at least every five years. Sometimes a one-time extens

Waste can be transported via three natural carriers-water, soil, and air. 1 S
35、TD.API/PETRO ES-ENGL L797 m 0732290 05b4b7b 957 W 2 API E5 All three media may provide pathways by which potentially polluting materials can migrate from their original source. Thus, materials used and wastes generated in exploration and production operations should be managed by considering risk to
36、 human health and the environment via media path- ways (see Figure 1). 1.3.1 Water Fresh water for human consumption, domestic needs, recreation, stock water, irrigation of crops, and industry comes from underground aquifers, lakes, streams, and reser- voirs. Materials from spills or improper waste
37、disposal may con- taminate aquifers. Of major concern are those aquifers that contain water suitable for drinking. Also important are aquifers used for agricultural purposes. Pollutants found in water are measured in concentrations of parts per billion (ppb); some of these pollutants may cause that
38、water to fail drinking water standards. The quality of aquifer waters can be degraded by pollu- tants to such a degree that it is not practical to restore the aquifer to drinking water standards. 1.3.2 Soil Most fresh water is stored in underground reservoirs Spills can adversely affect the capacity
39、 of soil to support called aquifers. Aquifers are part of a large water-recycling agricultural, industrial, human, and recreational uses. Soil system as illustrated in Figure 1.

Indirectly, gaseous wastes may alter the chemical balance in the atmosphere. Acid rain is a known result of al- tering the chemical makeup of the atmosphere.
44、 Ozone deple- tion and global warming are thought by some to be the result of human impact on the atmosphere. 1.3.4 Summary A properly implemented pollution prevention program can reduce or eliminate pollutant discharges to air, water, or land.

A good waste management system should include the following key elements: a. A system for maintaining knowledge of pertinent laws and regulations. b. A system for pollution preventiodwaste minimization. c. A health and safety program. d. An incident response preparedness program. e. A training program. f. A system for proper waste identification. g. A transportation program. h. A prope
