a. On January 9, 2013, the EPA issued a final rule to determine that the Air Basin has attained the 24-hour PM2s National AAQS. This action suspends federal State Implementation Plan planning requirements for the Bay Area. The Air Basin will continue to be designated nonattainment for the National 24-hour PM2.5 standard until such time as BAAQMD elects to submit a re -designation request and a maintenance plan to EPA and EPA approves the proposed re -designation.

Existing Ambient Air Quality Existing Air Quality Trends Existing levels of ambient air quality and historical trends and projections in the vicinity of San Leandro have been documented by measurements made by the BAAQMD. The Oakland Monitoring Station is the closest air quality monitoring station to the City. However, the Oakland Monitoring Station does not monitor PM10i therefore, data from the San Francisco Monitoring Station was used to supplement data for this criteria air pollutant. Data from these monitoring stations are summarized in Table 4.2-3. The federal PM2.5 standard has been exceeded several times in the last five years. The State 03 standard and the State PM10 standards have been exceeded only once in the last five years. The State and federal CO and NO2 and the Federal 03 standards have not been exceeded in the last five years in the vicinity of the City. Existing San Leandro Shoreline Development Emissions The Project site includes a total of approximately 75 acres, consisting of 52 acres of land and a 23 -acre public boat harbor. The boat slips are currently only 30 percent occupied (140 occupied boat slips), primarily due to the build-up of silt in the harbor and channel. The small fraction of boats within the harbor may be being used as housing.21 28 The current estimated population within the Project site is between 16 to 20 live -aboard residents, based upon correspondence between Steve Noack (PlaceWorks) and Delmarie Snodgrass, City of San Leandro, September 5, 2014.
