GB 4914-2008Effluent limitations for pollutants from offshore petroleum exploration and production (English PDF)

Foreword

The standard of Chapters 4 and 5 are mandatory, the rest are recommended. This standard replaces GB 4914-1985 "offshore petroleum development industry oily wastewater discharge standards." This standard and GB 4914-1985 phase Than the main changes are as follows:

--- Redefined the sea level (see Chapter 4);

--- Redefined the emission concentration limits for produced water contaminants (see Chapter 5);

--- Increasing the drilling fluid and cuttings emission concentration limits specified pollutants (see Chapter 5);

--- Increased provision requirements for offshore oil exploration and development of emissions generated in sewage and solid waste/concentration limit (see Chapter 5);

--- Increase the informative Appendix A "Extraction - Determination of the weight of the material can be extracted with n-hexane (HEM; Oil) and silica gel can be adsorbed Substance is extracted with n-hexane (SGT-HEM; Non-polar substances) "(see Appendix A), cited in Appendix A Part EPA USEPA1664A standard of technical content;

--- Increase the informative Appendix B "water-based and water-based drilling mud cuttings analysis of oil content" (see Appendix B). Appendix A of this standard and Appendix B is an informative annex. This standard was proposed by the State Oceanic Administration. This standard by the National Standardization Technical Commission for Oceanography (SAC/TC283) centralized. This standard was drafted. the National Marine Environmental Monitoring Center. The main drafters of this standard. Wangju Ying, Xu Lina, Han Geng Chen, ZHANG Zhi-feng, Zhaoyun Ying, Chen Chang Shu, Han Jianbo, Li Jun. This standard replaces the standards previously issued as follows:

--- GB 4914-1985. Offshore Oil Exploration Development of pollutant emission concentration limits

1 Scope

GB 4914-2008 is the Chinese national standard on effluent limitations for pollutants from offshore petroleum exploration and production, in the field of environment and health protection, safety. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 19 October 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 May 2009. Classification: ICS 13.060.30, CCS Z61. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the direct discharge of pollutants into the sea offshore oil exploration and development activities in the emissions concentrations in different sea areas Limit. This standard applies to waters, territorial sea and other waters within the jurisdiction of our country, to any legal person engaged in the exploration and development of petroleum and natural and other Direct discharge of the economic entity is used or generated in the job into the sea of produced water, drilling fluids, drill cuttings and other pollutants emissions management.
