Act for the Prevention of Marine Pollution and Maritime Disasters May 2007, the act was amended for permit procedure on

dumping CO2 stream into sub-seabed formation, reflecting London 1996 Protocol.

Prohibition of disposal of oils, noxious liquid substances and wastes under the seabed, except for• Oily matter resulting from exploration of mineral resources

in the seabed and sub-seabed• Gases consisting overwhelmingly of CO2 over 99%

(hydrogen production: over 98%)

Permit issued by Minister of the Environment (MOE) is required

Regulation for offshore CO2 storage


※Adapted from “Office of Marine Environment, Ministry of the Environment (March 27, 2017). Lessons learned from the permitting process for the first CCS project under the seabed in Japan.”

Application Documents for the Act Application form for a disposal permit

• Information on the representative of the applicant • Project execution plan • Monitoring plan (marine environmental survey plan) Attached documents

• Prior assessment on the marine environment • Site selection • Explanation for no reasonable measure other than

disposal in a geological formation under the seabed • Financial capability to proceed CCS and monitoring • Technical capability to proceed CCS and monitoring • Outline of the project

Marine Environmental Survey

Surveys in Three Stages

Methods of Survey• Current direction and speed survey

by Current Meter• Sampling of seawater by Water

Sampler for concentration of salt etc. and plankton observation

• Seabed mud survey by Bottom Sampler

• Collection of benthos by Net or Dredge Unit

• Observation of benthos by divers or ROV

• Before Injection: Baseline survey• During demonstration operation

Three phases of marine environmental survey Regular marine environmental survey (seasonal)

Precautionary marine environmental survey • Monitoring to judge whether or not a (potential) negative effect on the

marine environment have occurred/would occur.

Exceed the threshold※ CO2 injection shall be stopped

Exceed the threshold

Contingency marine environmental survey • Continuous monitoring to watch the event until no negative effect on

the marine environment caused by CO2 streams is confirmed.

• An applicant must report the monitoring result in each phase to MOE. • The threshold for each monitoring phase transition should be set by an

applicant within the monitoring plan.

result of seawater chemical analyses conducted Aug. 2013 to May 2014 before the injection.

cumulative injection of 7,163 tons. 25 May. to 31 Jul. 2016 : The injection was stopped in a planned way

for the yearly maintenance of the oil refinery and CCS plant facilities. 1 to 8 Jun. 2016 : Regular marine environmental survey (Spring) with

exceedance of the threshold Aug. 2016 : Restart of the injection was cancelled to conduct

precautionary and contingency marine environmental surveys. 28 Dec. 2016 : Supplemental permit application to MOE with a

revised marine environmental survey plan. 1 Feb. 2017 : Acquisition of regulatory approval from MOE 5 Feb. 2017 :Restart of CO2 injection to Moebetsu Formation
