CEQA Experience

Client: Los Angeles International Airport
Project: CEQA/NEPA Documents - Mitigation Measures Ranked by Cost-Effectiveness and Emission Reductions
(subcontractor to Camp, Dresser and McKee and URS Corporation)

ECS completed an extensive prioritization of emission reduction strategies while preparing air quality and environmental justice portions of the Environmental Impact Report and EIS for the Modernization of Los Angeles International Airport.

ECS completed all construction-related air quality analyses for the EIR and EIS and Supplemental EIR prepared for Los Angeles World Airport 's LAX project. The project included hundreds of pages of spreadsheet calculations broken out by each day of a 15-year construction buildout. Off-road engine factors along with SCAQMD CEQA Handbook data was used to complete the analyses. These calculations include numerous combinations of on-road (ie. truck and bus) calculations and emissions from off-road engines (ie. generators and construction equipment).

The project also included extensive evaluation of proposed emission reduction technologies including, but not limited to: new engines, emulsified fuels, low-sulfur diesel fuel and after combustion technologies such as diesel oxidation catalysts and PM filter traps. ECS reviewed and ranked over 100 mitigation measures as part of this task. Measures were evaluated on a cost-effectiveness basis; with cost-effectiveness expressed on a cost per ton of diesel PM10 and NOx reduced.

As part of these reports, ECS prepared draft deliverables consisting of 1) a written summary of each suggested measure and the assumptions used to derive each cost estimate; 2) an Excel spreadsheet outlining the range of potential costs and emission reductions associated with each measure; and 3) back-up documentation including all references used (ie. websites, telephone logs, emails from vendors, site visit notes, etc). Deliverables were presented in both electronic and hard-copy formats.

Client: Waste Management
Project: Bradley Landfill and Recycling Center MRF Conversion

This project includes transitional activities associated with the change from on-site landfilling to use of the site as a Transfer Station and Materials Recycling Facility (TS/MRF). ECS completed all air quality emission calculations, air dispersion modeling and health risk assessments contained in the Draft Environmental Impact Report (DEIR) prepared for this project.
