Lower Emission School Bus Funding Criteria

Funds are first distributed in proportion to the number of residents within each county.  School Districts in the county of  Los Angeles receive about 61 percent, Orange county receive18 percent, San Bernardino county receive 11 percent, and Riverside county receive 10 percent.  LA Unified School District, the largest school district in the AQMD jurisdiction, is restricted to a maximum of 50 percent of the total funds distributed to Los Angeles County, or roughly 30 percent.

Additional funding criteria are as follows:

Disproportionate Impact Areas

Assembly Bill 1390 (Firebaugh), approved by the State legislature, and signed into law by Governor Davis requires that at least 50 percent of the School Bus funds be allocated in communities that suffer  disproportionately greater exposure to poor air quality.  These include communities that are low-income and/or ethnic minority communities.

To implement standards of AB 1390, AQMD evaluates qualified projects in disproportionately impacted communities, according to the following criteria:

Poverty Level

Projects in communities with at least 10 percent of the population below the federal poverty level based on the year 2000 census data, and

PM Exposure

Projects in communities with the highest 15 percent of PM concentration.  The highest 15 percent of PM concentration is 46 micrograms per cubic meter and above, on a federal annual average, or

Toxic Exposure

Projects in communities with a cancer risk of 1,000 in a million and above.
Other projects will be ranked on a cost-effective basis, with the most cost-effective vehicles and equipment receiving the highest priority

Data for the poverty level and PM and toxic exposures were obtained from the U.S. Census, the 1998 AQMD monitoring data and Mates II study, respectively.

Disproportionate Impact Mapping

The map below illustrates the areas eligible for disproportionate impact funding.  All the areas illustrated in the map have poverty level of 10% or above, and either high cancer risk or PM exposure or both.  The areas with a cancer risk of 1,000 in a million and above are in gold; the areas with the highest 15% of PM exposure are in gray; and the areas with both the highest 15% of PM and a cancer risk of 1,000 in a million and above are in orange. This map forms the basis upon which School Bus funds were awarded.
