Environmental Impact Reports

How do we present the air quality impacts?

CEQA and NEPA require air quality impacts to be identified and mitigated in environmental impact reports (EIRs). BlueScape can help develop complete air quality impact sections of EIRs:

  • We will characterize the existing air quality.
  • We will calculate short-term and operational air quality emissions.
  • We will determine potential air quality impacts using dispersion models.
  • We will recommend mitigation options for impacts that may be significant.
BlueScape will not only help with the development of EIRs, but will also assist your project by presenting the facts on air quality impacts at public workshops and hearings.

When your company must meet these regulation requirements:

  • California Environmental Quality Act
  • National Environmental Policy Act
  • Local entitlement regulations

We provide the necessary technical services:
  • Development of complete air quality impact sections for EIRs
  • Characterization of existing air quality for the project site
  • Construction and operations, stationary source and mobile source emissions
  • Air dispersion modeling to address impacts from criteria pollutants
  • Health risk assessments for air toxic emissions
  • Recommendation of mitigation techniques for proposal in EIRs
  • Response to public agency inquiries and comments on EIRs
  • Presentation of project air quality impacts to the public in workshops and hearings
  • Review of air quality sections of EIRs for city or agency staff

We complete air quality impact sections of EIRs to ensure that the impacts are properly addressed and discussed by the involved public and agencies.

Sample Projects

Industry: Municipality
Client: Los Angeles World Airports
Prime Contractor: CDM & ECS

Air Dispersion Modeling Review; LAX Expansion in Los Angeles, California. The Master Plan environmental impact report for the proposed Los Angeles International Airport expansion involved substantial dispersion modeling to predict air quality impacts from both stationary and construction sources. Reviewed air dispersion modeling impacts from construction sources and recommend potential analysis refinements. The analysis, which discovered several needed corrections and possible technical refinements, was completed to prepare CDM staff to respond on behalf of Los Angeles World Airports to comments in public workshops.

Air Quality Impact Study; 500 MMBtu/hr Reheat Furnace in California. Completed an air quality impact analysis to support an environmental impact report for installation of a new, large Reheat Furnace #5. The work involved estimating maximum potential criteria pollutant emissions, and completing an air toxics health risk assessment. The air emissions study accounted for Reheat Furnace #5 emissions, removal of an old reheat furnace, and emissions increases from debottlenecked sources. The health risk assessment accounted for cumulative impacts from several sources near Reheat Furnace #5. The air quality impact study determined that NOx and PM10 emissions increases would be CEQA significant, and health risk impacts would not be significant.

Public Hearings in City of Escondido; Air Quality Impacts, Southern California. Represented air quality impacts before the public in workshops and hearings. PG&E DG sought City of Escondido approval for a 49 MW peaker power plant. The cityÕs regulations required an environmental impact report for daily emissions over stringent thresholds. Although PG&E DG and the Escondido Planning Commission staff agreed that the EIR thresholds did not apply to the project, the project received strenuous opposition from public members and City Council staff. Explained that air quality impacts would not exceed health risk thresholds if the project were allowed to proceed. The project won narrow approval in City Council review and was commissioned in early 2002.
