CALIFORNIA: AT BERTH REGULATIONS FOR AUXILIARY DIESEL ENGINE SUBMISSIONS
The Californian Environmental Protection Agency Air Resources Board (ARB) has issued an Advisory in November dealing with how they will enforce the At Berth Regulations intended to reduce emissions of diesel particulate matter and nitrogen oxides from auxiliary diesel engines while ships are at berth in Californian ports. There are two criteria that need to be satisfied, with effect from 1 January 2017:
- Visits : At least 70% of a fleet’s visits to a port must satisfy the following limit on engine operation : for each visit, the auxiliary engines cannot operate for more than three hours during the entire time the ship is at berth; and
- Power reductions : The fleet’s total onboard auxiliary engine power generation must be reduced by at least 70% from the fleet’s baseline power generation.
The ARB understands that it may not be possible to satisfy certain provisions in the Regulations under certain circumstances and so there are various scenarios that the ARB will apply and will look at each situation on a case-by-case basis. Members are advised to check with their local agents or correspondents to ensure that they comply with the Regulations.
