Bohai Bay Pollution Discharge Regulations

Discharge Standard for Oily Sewage in Offshore Oil Development Industry (GB49 14-85)

This standard is formulated to implement the Law of the People's Republic of China on the Protection of Marine Environment and prevent the environmental pollution caused by oily sewage from offshore oil development.

This standard is applicable to all enterprises, institutions, operators and individuals engaged in offshore oil development in all sea areas under the jurisdiction of People's Republic of China (PRC).

1 classification of standards

Oily sewage from offshore oil development industry refers to the oil production process sewage discharged from fixed sewage outlets after being treated on the oil production platform.

The discharge standard of oily sewage in offshore oil development industry is divided into two levels.

Grade I: It is suitable for Liaodong Bay, Bohai Bay, Laizhou Bay and Beibu Gulf, special marine protected areas designated by the state, and coastal scenic spots within equidistant shore 10 nautical mile.

Grade II: Applicable to the sea areas beyond the scope of application of Grade I standard.

2 standard value

The maximum allowable concentration of oily sewage discharge standard for offshore oil development industry shall comply with the provisions in Table 1. Mg/l

Allowable value of monthly average at project level

Oil grade 30 45

Secondary petroleum 50 75

Oil production process sewage should be reinjected into the formation to reduce sewage discharge.

Oily sewage from offshore oil development industry located in intertidal zone shall be subject to GB 3550-83 Discharge Standard of Water Pollutants for Oil Development Industry.

3 implementation and monitoring of standards

3. 1 From the date of implementation of this standard, the oil production platform that has started construction will immediately implement this standard. The existing oil production platforms shall implement Class II standard values from the date of implementation of this standard, and one year later, they shall be implemented according to the provisions of this standard.

3.2 For the oil production platform, monitoring sampling points should be set in the process sewage outfalls, and the environmental monitoring institutions of offshore oil enterprises are responsible for daily monitoring.

3.3 The monitoring and analysis methods of this standard shall be implemented with reference to Analysis Methods of Oily Sewage in Offshore Oil Development Industry.

Additional notes:

This standard was put forward by the Ministry of Urban and Rural Construction and Environmental Protection of People's Republic of China (PRC).

This standard was drafted by the writing group of Discharge Standard for Oily Sewage in Offshore Oil Development Industry.

This standard is entrusted to the State Oceanic Administration and the Ministry of Petroleum Industry for interpretation.
