No Scrubs: More ports declare ban on EGCS Discharges

Exhaust gas cleaning systems (EGCS) – more commonly referred to as scrubbers – are an accepted equivalent measure in complying with the IMO 2020 global sulphur cap. The use of scrubbers has split the shipping industry. Ports around the world are looking at the impact of scrubber use in their waters.

A number of ports and regions have already stated that they will not allow the discharge of washwater from scrubbers.

The table below summarises North’s understanding of the positions taken by ports that have or will prohibit the use of scrubbers, or have placed conditions on their use.

This information is to the best of our knowledge and is for guidance only. For up to date and definitive information, contact the local authorities or agents.
Country Port Open loop EGCS discharge allowed? Comments
Argentina All Yes – the prohibition is currently suspended Regulation No. 15/2020 of the Environment Protection Bureau, which came into force on 10 August 2020, prohibited the discharge of washwater from the exhaust gas cleaning systems (EGCS) of national or foreign-flagged vessels into Argentinean jurisdictional, sea or river waters.

Pandi Liquidadores S.R.L. advise that on 24 September 2020, Prefectura Naval Argentina issued Resolution DISFC-2020-22-APN-DPAM#PNA that suspended the enforcement of the above Resolution 15/2020.

IT&L Legal Consultants advise that this resolution took effect from 3 October 2020 and warn that this suspension is provisional, and the restrictions have not been permanently overturned.
Australia All Yes According to AMSA Marine Notice 05/2019, wash water testing should be conducted upon commissioning of the EGCS and repeated every twelve months, as a minimum, for a period of two years. Ships may be directed not to discharge wash-water from an EGCS in Australian waters if this data, or evidence that samples have been taken for analysis, cannot be provided to AMSA before arrival at the first Australian port.

Bahrain Bahrain No

• Open loop operation not allowed in port or at anchor
• Open loop operation is allowed in Bahraini territorial waters and exclusive economic zone (EEZ) as long as it can be proved that the discharge of washwater complies with MEPC.259(68) and there is no negative impact on marine ecosystems.

Belgium All No

• Belgian federal law states discharge only allowed in coastal and open seawaters when at least 3nm off coast
• Discharges must not imperil EU Water Framework Directive objectives.
• Flemish regional law also confirms discharge not allowed in ports or inland waters.

Bermuda All ports Yes The maximum allowed sulphur content in fuel for Controlled Plants is 2.0%. Ships equipped with Exhaust Gas Cleaning Systems (EGCS) shall seek the prior approval of the Environmental Authority before its use in Bermuda’s territorial waters. Wash-water and residue from the EGCS shall be not disposed of in Bermuda or discharged into Bermuda’s waters but shall be stored on board the ship until outside of Bermuda’s waters.

Brazil All (except Vale terminals) Yes Prior to 23 July 2020, advice received from local correspondents was “ based on existing provisions in national legislation, especially Law 9.966/00, the discharge of effluents generated by Scrubbers or Exhaust Gas Cleaning Systems (EGCS) is not allowed and the vessel, when in Brazilian waters, must operate with fuel within specifications (sulphur content up to 0.5% m/m)”.

However, correspondents Brazmar advised on 23 July 2020 that the Directorate of Ports and Coasts (DPC) / Navy have changed their previous guidance on the topic, and that the discharge of wash water from open loop and/or hybrid Exhaust Gas Cleaning Systems (EGCS) is allowed within Brazilian Jurisdictional Waters until the competent environmental authority has the opportunity to better assess the scenario.

This is under the assumption that the subject EGCS is approved by Class, has a plan for compliance of SOx emissions and is approved as per requirements of resolution MEPC.259 (68) of IMO.
Brazil Vale ports and terminals No Vale instruct arriving vessels that the discharge of EGCS washwater is not allowed while operating in its Brazilian ports and terminals.

Vale recommends that vessels should be changed over to compliant fuel before entering contiguous zone or coastal waters (24 nautical miles from coastline).

PR China Inland river Emission Control Areas (ECAs), Port areas within coastal ECAs and Bohai Sea – the sea area within lines connecting the junction point of shorelines of Dandong, Dalian and shorelines of Yantai, Weihai. No

China MSA guidance prohibits the discharge of water washings from open- loop scrubbers in certain areas. The prohibited areas are:
• Inland river Emission Control Areas (ECAs)
• Port areas within coastal ECAs
• Bohai Sea – the sea area within lines connecting the junction point of shorelines of Dandong, Dalian and shorelines of Yantai, Weihai.
• The guidelines also prohibit the incineration of the water washing residues from any type of exhaust gas scrubber. Ships are required to keep accurate records of the stowage and disposal of the washing washings.
• If a vessel is not able to store the washing water it is required to switch to low sulphur fuel (not exceeding 0.5%) prior to entering the above areas. The guidelines also state that under certain circumstances a vessel may apply for an exemption if it uses fuel that does not meet the MSA’s requirements.
• A copy of the MSA’s guidelines for ships operating within the ECAs, including enforcement details can be found here.

Egypt All ports and Suez Canal No Suez Canal:

• Suez Canal Authority has issued Circular 08/2019. Clarification on this circular is provided here

Estonia All Ports Restricted

https://veeteedeamet.ee/sites/default/files/content-editors/clarification_of_exhaust_gas_cleaning_system_egcs_operations_in_territorial_waters_and_ports_of_estonia.pdfCircular Number 4 (21.10.19) refers to paragraph of MEPC 184(59) and the restrictions on discharging chemical EGCS wash water including enclosed ports and estuaries. Exceptions for discharge into the sea are made if the ship operator can demonstrate that the washing water meets international requirements, required PH levels and does not cause adverse effects on human health or the environment. Prior authorisation is always required to discharge into the port area.The water Act which entered into force on 01.10.2019 does not treat washing water discharges as a violation of pollutant discharge from ships, if in compliance with MARPOL.The use of closed-loop EGCS is permitted in the territorial waters and ports of Estonia, if it meets the relevant requirements and is certified, however discharging of the washing water is not permitted.

Germany Inland Waterways , canals and ports within inland waterways No

The guidance is non-statutory, but MNZ encourages the industry to implement the following measures until work currently underway in respect to the use of scrubbers has been completed.

They request that all ships carrying scrubbers and operating in New Zealand’s territorial waters engage with the relevant port and regional authorities, and as a precautionary measure that where possible they avoid discharging scrubber effluent close to shore by utilising alternate options such as:

• preparing for entry into New Zealand waters by carrying compliant low sulphur fuel in order to use this when operating in sensitive environments, as identified by the relevant regional authorities.
• operating closed loop scrubber functionality in zero discharge mode and retaining any effluent on board until able to dispose of at the next available port facility.
• discharging any open loop scrubber washwater outside territorial waters.
