EXHIBIT 2 <br /> Santa Ana Blvd. Grade Separation <br /> provisions in Section 14-8.02, "Noise Control" of the Draft 2010 Standard Specifications and <br /> Special Provisions (SSP S5-310), and applicable local noise standards. <br /> The closest residences to the project site are within 50 feet from the project construction <br /> areas. Therefore, these residences may be subject to short-term noise reaching 95 dBA <br /> maximum sound level (L max) or higher generated by project construction activities. <br /> Proposed avoidance and/or minimization measures include: <br /> N-1 Comply with the construction hours specified in the City of Santa Ana Municipal <br /> Code, Noise Section 18-314. <br /> N-2 Noise control will conform to the provisions in Section 14-8.02 and Standard <br /> Special Provision S5-310. The noise level from the contractor's operations between the <br /> hours of 9:00 p.m. and 6:00 a.m. will not exceed 86 dBA L eq (h) at a distance of 50 feet. <br /> This requirement in no way relieves the contractor from responsibility for complying with <br /> local ordinances regulating noise levels. The contractor should use an alternative warning <br /> method instead of a sound signal unless required by safety laws. In addition, the contractor <br /> will equip all internal combustion engines with the manufacturer-recommended mufflers and <br /> will not operate any internal combustion engine on the job site without the appropriate <br /> muffler. <br /> N-3 The sound barriers that are determined to be reasonable and feasible shall be <br /> coordinated with the affected property owners. All benefited residents and property owners <br /> will be notified should a change in placement or removal of any soundwall occur during the <br /> design phase. Additionally, all residents/property owners will be notified of final soundwall <br /> locations prior to 100% PS&E. <br /> N-4 The contractor will implement appropriate additional noise mitigation measures, <br /> including changing the location of stationary construction equipment, turning off idling <br /> equipment, rescheduling construction activity, notifying adjacent residents in advance of <br /> construction work, and installing acoustic barriers around stationary construction noise <br /> sources. <br /> 6.2 Air Quality Assessment Report: <br /> The Air Quality Assessment Report determined that the project would have no adverse <br /> impacts under National Environmental Policy Act (NEPA). The determination is based on the <br /> following: <br /> • during project construction, the implementation of exhaust and fugitive dust emission <br /> control measures would avoid and/or minimize impacts to air quality; <br /> • the project is included in the Southern California Association of Government's <br /> (SCAG) 2008 Regional Transportation Plan (RTP) and SCAG 2011 Federal <br /> Transportation Improvement Program (FTIP) (Project ID ORA082610), which implies <br /> that project's operational emissions (which include the ozone precursors reactive <br /> organic gases (ROG) and oxides of nitrogen (NOX) meet the transportation <br /> conformity requirements imposed by EPA and the South Coast Air Quality <br /> Management District (SCAQMD). As such, the project would not exceed the motor <br /> vehicle emissions budget for the region; <br /> PROJECT REPORT EQUIVALENT 14 <br />
