The Raney Division has completed over 200 Air Quality Assessments and GHG Analyses for public and private sector clients throughout California. Raney’s air quality expertise ranges from private development projects, affordable housing projects, and large-scale specific plans, to unique and complex projects, such as mining and industrial projects. Over the years, Raney has developed excellent working relationships with local air quality management districts throughout California and through these relationships understand unique requirements for various air quality management districts. For example, Raney’s air quality team has prepared multiple Air Quality Mitigation Plans (AQMPs) and GHG Reduction Plans (GHGRP) for projects located in the Sacramento Metro Air Quality Management District’s (SMAQMD) jurisdiction. AQMPs are prepared for all projects that exceed the SMAQMD operational emissions thresholds to describe how air quality emissions for projects will be reduced and determines the level of reductions needed for each individual project. GHGRPs are prepared for projects with significant GHG impacts to recommend all feasible mitigation measures sufficient for a project to meet CEQA requirements and the regional climate change goals.

Raney’s air quality team has the ability and experience to prepare more advanced technical analyses. Raney has completed numerous Health Risk Assessments (HRAs) for project’s exposing nearby sensitive receptors, such as residential developments, to increased health risk impacts from toxic air contaminants associated with gas dispensing facilities, diesel truck trips, and/or construction equipment to name a few. Raney’s approach is to coordinate with local air districts to determine the appropriate level of analysis and threshold of significance depending on project specifics. Additionally, Raney’s air quality team also has experience preparing larger GHG policy documents for jurisdictions, such as Climate Action Plans (CAPs) which are comprehensive roadmaps that outline the specific activities that a jurisdiction will undertake to reduce GHG emissions.

What further separates Raney from other air quality firms is our unique understanding of how the air quality and GHG analyses fit into the overall CEQA/NEPA and planning process. Raney’s reports can be utilized as stand-alone documents in conformance with CEQA/NEPA or prepared in a manner that is easily incorporated into a larger CEQA/NEPA document, such as an Initial Study or Environmental Impact Report. Raney works closely with the lead agency, the air district, and the applicant to ensure that the mitigation measures are feasible, easy to understand, implementable, and straightforward to sign-off by the lead agency.

RANEY’S AIR QUALITY SERVICES INCLUDE, BUT ARE NOT LIMITED TO, THE FOLLOWING:

AQ

AIR QUALITY IMPACT STUDIES

Raney’s Air Quality (AQ) Impact Studies are prepared as stand-alone technical reports that may be included in CEQA and/or NEPA environmental documents for technical analysis. The studies are prepared with recommended models, such as CalEEMod, EMFAC, and CALINE4, and are in support of air district or other jurisdictional permitting approvals. The analysis includes construction and operational criteria pollutant emissions estimation, cumulative impact analyses, objectionable odor analyses, and localized carbon monoxide and toxic air contaminant (TAC) emissions analyses. Throughout the preparation of the Air Quality Impact Studies, Raney coordinates with the local air districts for guidance and recommendations to ensure the reports are adequately and accurately prepared.

GHG

GREENHOUSE GAS ANALYSES

The Greenhouse Gas (GHG) Analyses prepared by Raney can be used as stand-alone technical reports or be used for inclusion into CEQA and/or NEPA environmental documents. The analyses will be in compliance with relevant global climate change regulations, such as AB 32, SB 32, and SB 375, and with applicable local climate action plans. Raney’s familiarity with the local air districts guidance and recommendations provide them with the tools to prepare the analyses in a timely manner. Raney will use CalEEMod for estimation of construction and operational emissions and coordinate with local air districts. The analyses will be in support of air district or other jurisdictional permitting approvals.

HRA

HEALTH RISK ASSESSMENTS

Health Risk Assessments (HRA) are prepared with recommended models, such as A ERSCREEN, AERMOD, and HARP, and comply with the OEHHA Guidelines. Raney will use the models to obtain a TAC concentration estimation to use in calculating cancer and non-cancer risks. Raney will coordinate with local air districts throughout the preparation of the Health Risk Assessment to ensure accurate and adequate analyses.

AQMP

Air Quality Mitigation Plan

The operational Air Quality Mitigation Plans (AQMP) are prepared pursuant to the Sacramento Metro Air Quality Management District’s (SMAQMD) Guide to Air Quality Assessment in Sacramento County. The mitigation plans are prepared in compliance with SMAQMD’s Recommended Guidance for Land use Emission Reductions. Raney’s recommended mitigation measures are sufficient for the project to meet CEQA requirements and regional air quality goals.

GHGRP

GHG REDUCTION PLANS

GHG Reduction Plans (GHGRP) are prepared pursuant to the SMAQMD’s Guide to Air Quality Assessment in Sacramento County and prepared in compliance with SMAQMD’s Recommended Guidance for Land use Emission Reductions. Raney will recommend all feasible mitigation measures sufficient for the project to meet CEQA requirements and regional climate change goals. The measures used to prepare recommended mitigation will be chosen in compliance with any applicable Climate Action Plans and the California Air Pollution Control Officers Association (CAPCOA) Quantifying GHG Mitigation Measures guidance document.

CAP

CLIMATE ACTION PLANS

Health Risk Assessments (HRA) are prepared with recommended models, such as A ERSCREEN, AERMOD, and HARP, and comply with the OEHHA Guidelines. Raney will use the models to obtain a TAC concentration estimation to use in calculating cancer and non-cancer risks. Raney will coordinate with local air districts throughout the preparation of the Health Risk Assessment to ensure accurate and adequate analyses.

In addition to the above services, Raney provides on-call air quality advisory services to local jurisdictions as well as prepares air quality reports in support of environmental documents and State and Federal funding applications.
