NOx DPM, EIR, ESI… we know the acronyms used on this site can be confusing.

Below you can find definitions of terms and commonly used acronyms that will help you understand even more about the initiatives and projects the Port continues to implement to reduce our footprint and improve our community’s air quality.

 

Alternative Maritime Power: Also referred to as AMP, and also known as cold ironing or shore connection, it is the process of providing shore-side electrical power to a ship at berth while its main and auxiliary engines are turned off.

Air Quality Management District: Also referred to as the AQMD, specifically, the South Coast Air Quality Management District (SCAQMD), it is the local regulatory authority governing stationary air emissions in the South Coast Basin which includes the Port of Los Angeles. For more information, please visit the following website:  http://www.aqmd.gov/

Air Quality Monitoring: The Port of Los Angeles operates 4 air quality monitoring stations at different locations at and near the Port. The air quality monitoring stations measure ambient air pollution levels in the vicinity of the Port. The program includes a number of real-time air quality measurements: ozone, sulfur dioxide, nitrogen dioxide, carbon monoxide, two sizes of particulate matter, polycyclic aromatic hydrocarbons, and ultrafine particles. For real-time data, please visit caap.airsis.com.

Air Quality Report Cards: Published alongside the annual emissions inventory (see Inventory of Air Emissions) these are concise report cards that give a breakdown of the emission reduction statistics compared to the baseline year of 2005 for the 5 major sources that service the port. To view report cards, visit: https://www.portoflosangeles.org/environment/studies_reports.asp

AMP: See Alternative Maritime Power.

CAAP: See Clean Air Action Plan.

California Environmental Quality Act: A statute that requires state and local agencies to identify the significant environmental impacts of their actions and to avoid or mitigate those impacts, if feasible.

CARB:  See California Air Resources Board

California Air Resources Board: The California Air Resources Board (CARB) is part of the California Environmental Protection agency. CARB is tasked with promoting and protecting public health, welfare, and ecological resources through the effective and efficient reduction of air pollutants. For more information, please visit the following website: http://www.arb.ca.gov/homepage.htm

Clean Air Action Plan: Also known as the CAAP, is a joint initiative between the Ports of Los Angeles and Long Beach to improve air quality in the South Coast Air Basin. The CAAP is a sweeping plan aimed at significantly reducing the health risks posed by air pollution from port-related ships, trucks, trains, cargo-handling equipment and harbor craft.  The plan is widely acclaimed to be the most comprehensive strategy to cut air pollution and reduce health risks ever produced for a global seaport complex. For more information, please visit the following website: www.cleanairactionplan.org.

CEQA: See California Environmental Quality Act.

Clean Truck Program: Also referred to as the CTP, is a central element of the Clean Air Action Plan which targets the reduction of air pollutants from the heavy duty drayage trucks that service the Port.

For more information, please visit the following website: https://www.portoflosangeles.org/ctp/idx_ctp.asp

CTP: See Clean Truck Program

Diesel Particulate Matter: Commonly referred to as DPM, is a pollutant produced as a result of burning diesel fuel in the various port-related ships, trucks, trains, cargo-handling equipment and harbor craft.

EIR: See Environmental Impact Report

Environmental Impact Report: Also referred to as an EIR, this report is prepared to inform governmental agencies and the public of a project’s environmental impacts. An example of a Port EIR can be found at: https://www.portoflosangeles.org/environment/compliance_trapac.asp

Environmental Protection Agency: The United States Environmental Protection Agency (EPA) is the federal agency which issues and manages environmental regulations, with the mission to protect human health and the environment. For more information, please visit the following website: https://www3.epa.gov/

Environmental Ship Index:  The Environmental Ship Index (ESI) identifies seagoing ships that perform better in reducing air emissions than required by the current emission standards of the International Maritime Organization. The ESI evaluates the amount of nitrogen oxide (NOX), sulphur oxide (SOX) that is released by a ship and includes a reporting scheme on the greenhouse gas emission of the ship. For more information, please visit the following website: http://esi.wpci.nl/Public/Home

EPA:  See Environmental Protection Agency

ESI: See Environmental Ship Index

Expanded Greenhouse Gas Inventory: A document prepared by the Port of Los Angeles that specifically analyzes the Greenhouse Gasses (GHGs) produced at the Port. It is compiled every five years. The next report will cover calendar year 2015. For the latest inventory, please go to: https://www.portoflosangeles.org/environment/studies_reports.asp

GHG: See Greenhouse Gas Inventory

Inventory of Air Emissions (IE): Also known as the IE, is the Port’s annual report which catalogues the air emissions produced by operations at the Port of Los Angeles. These reports provide calculations for the air emissions generated by the five major source categories (ships, trucks, trains, cargo handling equipment and harbor craft) that service the Port and provides total emission reductions compared to the baseline year of 2005. To view reports, please go to: https://www.portoflosangeles.org/environment/studies_reports.asp

Nitrogen Oxides: Commonly referred to as NOx, is a pollutant produced as a result of burning fossil fuels in the various port-related ships, trucks, trains, cargo-handling equipment and harbor craft.

Ocean Going Vessel Emission Reduction:  Through various programs found in the Clean Air Action Plan, such as the Environmental Shipping Index and Vessel Speed Reduction programs, the Port of Los Angeles has worked closely with the operators of Ocean Going Vessels (OGVs) to reduce pollution.

Sulfur Oxides: Commonly referred to as SOx, is a pollutant produced as a result of burning fossil fuels in the various port-related ships, trucks, trains, cargo-handling equipment and harbor craft.

TAP: See Technology Advancement Program.

Technology Advancement Program: Also known as the TAP, is a key program in the port’s Clean Air Action Plan, aimed at accelerating the verification or commercial availability of new, clean technologies, through evaluation and demonstration, to move towards an emissions free Port. The TAP provides grant funding to support the development of clean technologies for use at the Port. For more information on the TAP, please visit the following website: http://www.cleanairactionplan.org/programs/tap/default.asp

TEUs:  See Twenty Foot Equivalent Units

Twenty Foot Equivalent Units: This is a unit of measurement used for discussing containerized goods movement. Each Twenty Foot Equivalent (TEU) is the volumetric equivalent to a 20 foot long container.

Vessel Speed Reduction Program: The Vessel Speed Reduction Program (VSRP) is a control measure in the Clean Air Action Plan. Through this program, the Port of Los Angeles offers a dockage rebate to vessels operators for reducing their speeds at the Port, typically lower than 12 nautical miles per hour, which maximizes their fuel efficiency.

VSRIP:  Vessel Speed Reduction Incentive Program. See Vessel Speed Reduction Program

VSRP:  See Vessel Speed Reduction Program

Water Resources Action Plan: Also referred to as the WRAP, the Port of Los Angeles and Long Beach expanded their water quality programs with the development of a coordinated Water Resources Action Plan, a comprehensive effort to target remaining water and sediment pollution sources in the San Pedro Bay.
