January Update: 

Air Sample Summary:

Results are within typical regional background levels as reported in studies conducted by the SCAQMD.  Results from the City’s air monitoring program showed concentrations that are less than all published health-based reference exposure levels developed by the California Office of Environmental Health and Hazard Assessment (OEHHA). The reference levels developed by OEHHA are used by agencies and health risk managers to evaluate the hazard associated with exposure to a specific chemical contaminant and the impact it has on target organs in the human body.

Air Sampling and Health Risk Assessment

Although oversight and enforcement of emissions from the All American Asphalt Plant lies with the Southern California Air Quality Management District (AQMD) and is not within the City’s purview, the City of Irvine has taken significant and unprecedented steps to evaluate the health risk at the plant and to protect residents. The City has commissioned a comprehensive ambient air monitoring program.  The sampling began in December and will analyze for over 120 chemical compounds specifically identified due to their association with rubber asphalt processing equipment and operations. This sampling methodology also follows standards set by AQMD and the Environmental Protection Agency (EPA) that will facilitate the evaluation of potential health risks, odor nuisance, and exceedance of regulatory limits. This sampling  began in November 2020, and will take place at four separate locations at the plant and within the community during November 2020 and January 2021. Results will be published on the City website as soon as they are available. The air sampling data will serve as the basis for a subsequent Health Risk Assessment that will determine whether there is a potential public health risk that warrants further evaluation. The Health Risk Assessment will also be made available publicly once it is complete.

Scope of Services

Ninyo & Moore will provide environmental consulting services for the City of Irvine relating to the All American Asphalt plant located at 10671 Jeffrey Rd, Irvine, CA.

Site Audit and Permit Review

The City has commissioned an audit of the All American facility to verify compliance with all relevant permits.  Although the All American Asphalt Plant was approved by the County of Orange in the 1990s, prior to property becoming part of the City of Irvine, the City is underway on a comprehensive review to ensure that the plant is operating consistent with all relevant land use and other regulatory permits. This extensive review of historical documents and inspection of the plant property is being performed to ensure that all equipment and facilities have been properly permitted and are being operated consistent with their approvals. The review will also verify that there have not been any illegal expansions of the facility beyond its current approvals.

December 21 Update:

In response to community concerns, South Coast AQMD is conducting a short-term air sampling and analysis initiative near the All American Asphalt facility. The first sample was collected on December 2, 2020 and additional samples will be taken every six days for approximately two months. South Coast AQMD reports that the sample taken on December 2, "Results are within typical background levels and below health-based exposure levels." Read more here

November 17 Update:

The Irvine City Council sent a letter to South Coast Air Quality Management District requesting for transparent and proactive measures to address ongoing and potentially dangerous emissions in the City of Irvine pertaining to both All American Asphalt and the Frank R. Bowerman Landfill. The Irvine City Council respectfully requests the following immediate actions pertaining to both the All American Asphalt facility and the Bowerman Landfill:

  1. For AQMD to hold a public meeting in Irvine in order to listen to and understand the concerns of those that are being affected and to give an update on the agency’s progress in resolving the underlying causes of the problems in our community.
  2. Given the long-standing concerns about All American Asphalt and the noxious odors emanating from the Bowerman Landfill, we are requesting that community air monitoring facilities be established by AQMD in appropriate locations in and around the City of Irvine to evaluate emissions and potential health risks from both of these sources on an ongoing basis.

October 15 Update and Letter to Residents:

As you may be aware, there is a manufacturing facility in the North Irvine area which we believe is producing odors that are creating a growing public nuisance for residents.  We want you to know that we understand the concern of residents in the area and that the City is taking all actions within its power to eliminate the problem.  The source of the odor is the All American Asphalt plant located north of Portola Parkway.  The plant has been in place for many years and was approved by the County of Orange, prior to the land being incorporated into the City of Irvine.

Regulation of manufacturing emissions and odors, such as those that are likely being released by the plant, lies with an agency called the Southern California Air Quality Management District (AQMD).  Over the last year, the City has worked hard to get AQMD to bring enforcement actions at the plant that would eliminate the odors but, to date, the agency’s actions have fallen short.  Because of this failed enforcement by AQMD, the City is taking all actions within its power to solve the problem.  Earlier this year, the City filed a lawsuit against All American Asphalt for creating a public nuisance.  This extraordinary legal action by the City on behalf residents allows the City to gather information about the plant operations and could allow the City to force a solution that will eliminate the source of the problem.  The City is also leveraging its land use authority to eliminate any expansion of the plant or its manufacturing process beyond the original County approvals, which may be the source of the odor. 

While primary enforcement responsibility lies with AQMD, and the City does not have the power to immediately close the plant or eliminate the odor, please know that the City, through its lawsuit and land use authority, is taking all possible steps to solve the problem as quickly as possible.  The City has established this new web page at , which has a map and will provide updated information regarding efforts to address the problem.  If you notice asphalt odors in the area, we encourage you to register your complaint with AQMD via:

Thank you,

Irvine City Council
