Please note that the Gateway Cities Council of Governments Transportation Committee meets at 4:30 p.m. on the same day as the scheduled GCCOG Board Meetings.

What is the Gateway Cities Air Quality Action Plan?

The Gateway Cities Air Quality Action Plan (AQAP) is a subregional study requested by the I-710 Oversight Policy Committee (OPC) in 2004 to "develop suggested steps for initiating the development and implementation of a corridor level Air Quality Action Plan to include not only technical, but also funding, institutional structure and legislative strategies as well as an approach to holding public agencies with jurisdiction in the corridor accountable for progress in meeting air quality and public health objectives in the corridor and the region." It will assess how to continue to improve air quality and public health by addressing both near-term and long-term measures for emission reductions.

Who are the Project Participants?

The Gateway Cities Council of Governments (GCCOG) is preparing the AQAP with administrative management and support from Los Angeles County Metropolitan Transportation Authority (Metro).

What are the AQAP Objectives?

The intent of the AQAP is to continue to seek air quality improvements and reduce health risks in Gateway Cities by establishing a framework to help organize and focus the activities of its member cities toward this common goal.   The AQAP will build on air quality improvement projects and programs already underwayand evaluate further actions that can be undertaken to maximize effectiveness of those projects and programs.  The AQAP will develop conceptual plans to further implement and measure air quality improvements in the region.  The framework will address specific measures to minimize negative air quality impacts and health issues, as well as seek and identify funding opportunities and legislative strategies to support and implement any additional measures.

What are the major components of the AQAP?

Compendium - This Compendium will update two previously prepared compendiums and will provide a comprehensive list of all existing and potential future air pollution reduction measures in the study area that could benefit the Gateway Cities.  Additional research will include identification of recent studies, projects and programs and interviews with stakeholder agencies and community groups.

Quantitative Air Quality Analysis - This analysis and evaluation covers the total expected air quality impacts and benefits of the measures included in the updated Compendium.  It will also provide an analysis of near roadway modeling for the transportation improvements proposed in the I-710 Corridor Project and the potential air quality impacts from an estimated I-710 Construction Staging and Phasing scenario.

Qualitative Air Quality Analysis for I-710 - The AQAP will also include research of potential air quality impacts from Ultrafines.

Health Impact Assessment for I-710 - A Health Impact Assessment (HIA) will be performed to assess the improvements proposed in the I-710 Corridor Project, and to make recommendations to evaluate opportunities for improving health indicators related to specific actions or proposals.  Three major steps for conducting the HIA are:

  • Scoping, where health determinants for evaluation and methods for analyses are identified;
  • Conducting the assessments using both quantitative and qualitative analysis; and
  • Communicating the results of the assessment.

As part of the HIA process, prioritized health issues will be evaluated; populations to be analyzed will be identified (e.g., vulnerable populations based on age, place of residence, race/ethnicity, and/or income); and research questions will be prioritized for each health issue.  An HIA Advisory Working Group, reflective of the diverse interests, will be formed to make recommendations as part of the HIA process.

Community Medical Needs Assessment - This assessment will evaluate and report on current health conditions and treatment in the Gateway Cities.  This will include selection and analysis of indicators related to:

  • health outcomes;
  • factors that contribute to population health (e.g., transportation, environmental quality, housing, etc.); and
  • factors that contribute to population health that are not addressed in an EIR/EIS (e.g., access to and quality of medical care, access to healthy food, etc.).

Gateway Cities Health Risk Assessment (HRA) - The HRA will evaluate the impacts to public health as a result of changes from proposed actions in the Air Quality Action Plan (AQAP) for the Gateway Cities subregion.  The HRA will provide policy makers and the general public with additional information regarding which air quality improvement measures may yield the greatest reduction in health impacts.  This will provide a catalog of potential benefits to the Gateway Cities communities that result from the suite of measures listed in the Compendium, the HRA report and other details that may be developed by the AQAP process.

What is the project schedule?

The AQAP will be developed over a 24 month timeframe.

When can I provide input?

There will be many opportunities for you to participate in the AQAP.

Public meetings will be held throughout 2011 and 2012. The purpose of these meetings is to provide an understanding of the AQAP project and to provide stakeholders with an opportunity for input and feedback into the process.
