Sulfur dioxide data is from the Costa Mesa station on Mesa Verde Drive. <br />Source: Michael Brandman Associates, Air Quality Analysis Report, 2009. <br />Sensitive Receptors <br />Those who are sensitive to air pollution include children, the elderly, and persons with preexisting <br />respiratory or cardiovascular illness. For purposes of CEQA, the SCAQMD considers a sensitive <br />receptor to be a location where a sensitive individual could remain for 24 hours, such as residences, <br />hospitals, or convalescent facilities. The nearest sensitive receptors are the existing onsite buildings <br />of the Town and Country Manor, located less than 10 feet from the proposed modifications. <br />4.2.3 - Regulatory Setting <br />Air pollutants are regulated at the national, State, and air basin level; each agency has a different level <br />of regulatory responsibility. The United States Environmental Protection Agency (EPA) regulates at <br />the national level. The ARB regulates at the State level. The SCAQMD regulates at the air basin <br />level. <br />Michael Brandman Associates 4.2 -3 <br />H\Cl t(PN- JMb327b327003MMVB270030 Se 4GAvQ Iity.DOc <br />
