6. Future background carbon monoxide concentrations are pro- jected to exceed the 8 -Hour state and federal standards. Consequently, regardless o£-the alternative, Caline 3 mode- 1 ling indicates that carbon monoxide levels at the intersec- tions analyzed will exceed the 8 -hour standards at the intersections analyzed. 7. The project is consistent with the Air Quality Management Plan (AQMP) and the State Implementation Plan (SIP) Air Quality Mitigation Measures Measures selected for incorporation in the project include: [ 1. SCAQMD Rule 403 (see page 10 of the Appendix) will be ad- hered to, insuring the clean up of construction- related dirt on approach routes to the site. 2. Adequate watering techniques will be employed to partially mitigate the impact of construction - generated dust particu- lates. 3. Construction equipment will be properly maintained and ser- viced to minimize exhaust emissions. 4. Consideration will be given to the provision of convenient bus shelters and bus turnouts along Bristol Street to en- courage the use of public transportation. Additional mitigation measures offered for consideration and incorporation in the project if found to be feasible: 5. The use of energy efficient lighting along Bristol Street (low pressure sodium vapor lights) should be considered to reduce emissions at the power plant serving the area. (AQMP control measure Nll) r 6. Traffic signals along Bristol Street should be synchronized l if feasible. (AQMP control measure K2) 7. Construction activities should be halted during stage One and Stage Two smog alerts. 1.2 Acoustic Summary Existing Acoustic Environment 1. Ambient noise levels in the project area are affected pri- marily by motor vehicle noise emanating from Bristol Street. 2. The project site is far removed from public, military and private airports, railroads, and other significant noise generators. ' 1 -2 75C -427
