Ambient and Stationary Source Air Quality Monitoring

In order to receive permits to construct or operate a facility in California, air emissions must be first analyzed and modeled for the project as part of CEQA and NEPA environmental assessments. However, even after the project is approved, Ambient and Stationary Source Air Quality Monitoring may still be required to monitor actual levels of air emissions, including toxic air contaminants, dust, and other emissions.

ECORP performs ambient and stationary source air quality monitoring for a variety of purposes including public relations, AB 617 community air grants, and to help settle lawsuits brought against a facility.

How Does ECORP Perform Ambient & Stationary Source Air Quality Monitoring?

ECORP monitors ambient air quality monitoring by installing sensors around a facility, typically along the fenceline. Fenceline monitoring ensures that all contaminants created by stationary sources of air emissions are accounted for as they leave the facility. Using sensors at different locations can also help ECORP identify where the greatest sources of pollutants are coming from and generate air quality mitigation plans to reduce levels to safe, legal limits when needed.

Why Perform Ambient and Stationary Source Air Quality Monitoring?

The simplest reason a builder or facility operator may be required to monitor air quality is to ensure that air pollutants released by the facility remain below legal thresholds and do not threaten human health or nearby wildlife. However, there are several other reasons project proponents, developers, facility operators, construction contractors, and other stakeholders might desire ambient and stationary source air quality monitoring services as outlined below.

Ambient Air Quality Monitoring for Public Relations

Many facilities monitor ambient air quality around their facility to maintain good public relations. By being able to show others that air emissions are safe and below legal thresholds, facility owners and operators build good relationships with their community and build a brand culture focused on sustainability.

Community Air Grants as Part of AB 617

California Assembly Bill (AB) 617 is designed to ensure that everyone in California is benefiting from the state’s efforts to improve air quality. Included within AB 617 is a provision for community-based organizations to receive Community Air Grants. As part of these grants, organizations are encouraged to hire consultants and technical experts like ECORP to monitor ambient and stationary source air quality of facilities that may be producing excessive air pollutants.

Settle Emissions-Based Lawsuits with Air Quality Monitoring

ECORP’s air quality monitoring is often used to help settle lawsuits brought against facilities that allege air emissions during construction or facility operations exceed legal limits. By monitoring ambient air quality around the fenceline of a facility, ECORP can help determine the truth of these allegations. If air emissions prove to be excessive, ECORP can develop air quality mitigation plans to help you reduce the pollutants and settle the lawsuit amicably.

Types of Sensors Used for Ambient and Stationary Source Air Quality Monitoring

To ensure legal defensibility of our ambient and stationary air quality monitoring services, ECORP uses federally regulated sensors and methods for assessing the total amount of air pollutants exiting a facility. Additionally, we also use low-cost, next-generation sensors such as the Purple Air models for community relations and AB 617 community grants or when the situation warrants.
