Harbor Boulevard Mixed Use Transit Corridor Plan Findings and Facts in Support of Findings and Statement of Overriding Considerations and would significantly contribute to the particulate matter (PM10 and PM2.5), ozone (03), and nitrogen dioxide (NO2) nonattainment designations of the SoCAB. Finding: 3. The City makes Finding 3 and determines that this impact is significant and unavoidable. Facts in Support of Finding Mitigation Measures 2 -1 through 2 -3 would reduce criteria air pollutants generated from project - related construction activities. Buildout of the Harbor Boulevard Mixed Use Transit Corridor Plan would occur over a period of approximately 20 years or longer. Construction time frames and equipment for individual site specific projects are not available. There is a potential for multiple developments to be constructed at any one time, resulting in significant construction related emissions. Therefore, despite adherence to Mitigation Measures 2 -1 through 2 -3, this impact would remain significant and unavoidable. Mitigation Measures MM 2 -1 Applicants for new development projects within the Harbor Boulevard Mixed Use Transit Corridor Plan shall require the construction contractor to use equipment that meets the United States Environmental Protection Agency (EPA)- Certified emissions standards according to the following schedule. • From the end of 2011 to December 31, 2014, all project - related off -road diesel - powered construction equipment greater than 50 horsepower shall meet Tier 3 off -road emissions standards. Any emissions control device used by the contractor shall achieve emissions reductions that are no less than what could be achieved by a Level 3 diesel emissions control strategy for a similarly sized engine, as defined by CARB regulations. After January 1, 2015, all off -road diesel - powered construction equipment greater than 50 horsepower shall meet the Tier 4 Final emission standards. Any emissions control device used by the contractor shall achieve emissions reductions that are no less than what could be achieved by a Level 4 diesel emissions control strategy for a similarly sized engine, as defined by CARB regulations. Prior to construction, the project engineer shall ensure that all demolition and grading plans clearly show the requirement for EPA Tier 3 or higher emissions standards for construction equipment over 50 horsepower. During construction, the construction contractor shall maintain a list of all operating equipment in use on the project site for verification by the Building Safety Division. The construction equipment list shall state the makes, models, and numbers of construction equipment onsite. 20 July 2014
