The Environmental Health Coalition (EHC) is a San Diego-based environmental justice organization founded in 1980 by Diane Takvorian and Tony Pettina. It works with low income communities and communities of color in the San Diego region and along the U.S.-Mexico border to address environmental health risks related to excessive amounts of pollution and other environmental hazards such as hazardous air pollutants, toxic waste disposal facilities, and superfund sites. The coalition also addresses risks related to land-use planning, transportation access, and community development. EHC has participated in community research, environmental health advocacy, and policy initiatives addressing disproportionate environmental impacts in affected neighborhoods, as part of its mission statement.

History The Environmental Health Coalition was founded in 1980, originally under the name "Coalition Against Cancer". Reports of waste haulers that were dumping toxic chemicals in Barrio Logan helped catalyze the organization's change. These incidents reflected a broader conflict between industrial land use and residential neighborhoods in Barrio Logan, which became an early point for environmental justice organization in San Diego. The initial focus of the EHC was to clean up toxic waste sites like the 38th and Alpha street dumps.

In 1983, EHC launched the Household Toxics Project, which focuses on identifying and removing environmental contaminants in local houses. The organization also helped develop one of California's earliest programs to separate household hazardous waste from municipal garbage streams. In 1986, the EHC co-sponsored the Tijuana Toxics Conference, and in the same year, launched the Toxic Free Neighborhoods and Clean Bay Campaigns. EHC also documented hazardous waste shipments from the United States to facilities in Tijuana and helped bring attention to boarder environmental health risks affecting nearby communities. In 1994, the EHC launched SALTA (Salud Ambiental Lideres Tomando Accion or Environmental Health Leaders Taking Actions), which aimed to train locals in environmental health and justice. In 1996, the EHC protested the housing of nuclear aircraft carriers in San Diego Bay. In 2000, the EHC worked to draft the Military Responsibilities Act, and in 2002, it formed the Tijuana affiliate. In 2005, the coalition supported efforts to restrict diesel truck traffic on residential streets in Barrio Logan, a policy that intended to reduce residents' exposure to air pollution from nearby industrial-related transportation. In 2010, the EHC got the West Side National City Specific Plan approved, and oversaw energy stimulus money going towards San Diego residents of low income.

Leadership

Diane Takvorian is one of the founders of the EHC. She has been the executive director since 1982, and holds a master's degree in Social Work with a focus in public policy. She has served on advisory boards at the state, national, and international level. She was appointed to the Joint Public Advisory Committee for the NAFTA Commission for Environmental Cooperation in 2009 by former president Barack Obama.

In 2008, she was awarded the James Irvine Foundation Leadership Award for her work in environmental justice issues in California. In 2016 she joined the California Air Resources Board, a statewide board responsible for creating programs that manage air pollution and aims to fight climate change.

Tony Pettina, a co-founder of the EHC, served as the treasurer of the board of directors from 1980 to 2006.

Joy Williams served as the organization's research director from 1987 to 2020, and received the Haagen-Smit Award by the California Air Resources Board in 2019 for contributions to air quality research.

Mission and approach For more than four decades, EHC has developed campaigns and initiatives that reflect its longstanding focus on social justice and against environmental racism, while also showing how their work has expanded across multiple issues such as toxic pollution, land use planning, policy advocacy, and environmental health research. The historian Andrew Wiese describes EHC as an important actor in San Diego's environmental justice movement and notes that the organization developed a broad understanding of "the environment", that went beyond conservation-oriented environmental groups, that included the urban places where residents lived, worked, and played.

A central part of EHC'S approach is community-driven planning, in which resident participate in identifying environmental health concerns, sharing information within their communities and pushing for policy changes related to pollution, land use and public health. SALTA (Salud Ambiental Líderes Tomando Acción) is one example of this approach, being a training program that teaches community leaders about organizing, policy advocacy, environmental health and public communication. Relatedly, EHC's Community Action Teams are groups of local residents who receive leadership training and may also serve on boards, commissions, planning groups, and school-related committees.

EHC has also used community-based participatory research as part of work. A study about the Toxic Free Neighborhoods Campaign in Old Town National City, explains that EHC combined internal research with the training of "promotoras de salud" (lay health promoters) who participated as both community researchers and advocates in local environmental health and land-use policy efforts.

Another important aspect of ECH's work involves building partnerships with other organizations that share EHC's ideology. In this way, the EHC aims to work on a local, state, national and international levels to address social and environmental issues.

Community-based participatory research The Environmental Health Coalition participated in a community-based participatory research study that examined the effects of industrial activity in Old Town National City, California. The study observed links between community conditions and policy development, and supported efforts to increase the public awareness of environmental health risks in the specific area.

Work on National City

EHC has worked with residents of National City since at least 2005, especially in Old Town, on the city's west side. An important part of their efforts in this community have focused on improving food security in the area. According to EHC, the area is established as a food desert, which is defined as "part of the country vapid of fresh fruit, vegetables, and other healthy whole foods". Limited access to fresh food has been associated with increased risks of diet related health conditions. In all of San Diego, National City has the highest rate of heart attacks. Together with the EHC, the community has reached out to officials to establish a city garden to combat food insecurity within the city. The EHC intends to continue working with Old Town with the goal that they longer have food desert status.

Through community-based planning, EHC and Old Town residents developed a land-use plan that reflected residents' priorities for a healthier neighborhood. EHC's work in National City has also addressed the relationship between residential areas and industrial land uses. In 2025, KPBS and Voice of San Diego reported that the National City City Council unanimously rejected a proposed biofuel transfer station on the city's west side after opposition from residents and environmental groups, including EHC. The proposed project would have added truck and rail activity to an industrial area already affected by air pollution and heavy industry.

Barrio Logan Barrio Logan is a neighborhood in San Diego that is concentrated with waste and recycling facilities, an interstate running through it, and an outdated city plan.Keatts, A. (2013, September 16). Everything You Need to Know About the Barrio Logan Community Plan. Voice of San Diego. https://voiceofsandiego.org/2013/09/16/everything-you-need-to-know-about-the-barrio-logan-community-plan/‌ Industrial land use conflicts in Barrio Logan played a large role in the emergence of environmental justice activism in San Diego. The EHC has worked with underserved communities such as Barrio Logan on environmental health and pollution issues. The community of Barrio Logan is in the process of notifying the local government of these issues with the help of the EHC. The Office of Environmental Health Hazard Assessment and the EPA developed a method of screening called CalEnviroScreen 3.0, and determined that Barrio Logan contains a disproportionate number of pollution sources. City planners and local government drafted a new plan, disregarding the community's ideas and inputs. The neighborhood voted against the city planners' version, so no resolution was reached, and the city plan from 1978 remains. They are still making an effort to gain momentum for their 2013 plan, and are still trying to reach a resolution.

Truck ordinance for Barrio Logan

In 2018, the EHC achieved its goal of cleaner air and public health in Barrio Logan by reducing the frequent heavy duty truck activity on local streets. Before the ordinance was unanimously passed, the residents of Barrio Logan dealt with excessive air and noise pollution. The residents of Boston Avenue in Barrio Logan participated in a traffic survey, which showed that up to 59 heavy duty vehicles drive down Boston Avenue in any given two-hour period.

The effort to reduce the effects caused by diesel-powered machines was led by David Alvarez, chair of the San Diego Environment Committee. Though the policy has been in effect for some time, it currently does not prohibit the use of diesel trucks on all streets. Some schools, retirement homes, and residential areas remain exposed to diesel related air pollutants such as ultrafine particulate matter. The EHC has advocated for the implementation of stricter penalties and enforcement of policy. They recommend a truck route as a solution to combat this issue.

Arroyo Alamar Preservation Initiative

The Arroyo Alamar river is a binational body of water that originates from Eastern San Diego County, and is one of Tijuana's last native wildlife hotspots. Human emissions have led to a decline in biodiversity, including the loss of habitats for waterfowl, mammals, marine life, amphibians, and crustaceans. The EHC has worked to preserve the land and prevent further construction and habitat destruction by hosting educational tours for the community in order to generate public awareness. The initiative also involves cross-border coordination with organizations in Tijuana and Mexican authorities in order to protect the Alamar riparian forest.

Transit for All San Diego's transit system plays an important role for families, economy, health, and environment. However, many working families in San Diego County struggle to access job opportunities, visit doctors, and get groceries, due to the lack of accessibility in the current transit system. In the San Diego region, passenger and light-duty vehicles are the largest contributor of greenhouse gas emissions. Adding more transit systems can reduce this. The EHC and the San Diego Transportation Equity Working Group are working toward a more reliable and accessible transit system, while reducing greenhouse gas emission and lung-damaging air pollution. Along with these goals, it should meet the needs of individuals of any race and class, especially the low-income communities of color in Barrio Logan, City Heights, and National City. The MTS Board of Directors approved a plan to transition to 100% bus electrification by 2040. They are starting this plan by prioritizing having pollution-free buses in communities that have experienced the most impacts of greenhouses emissions.
