Citizens, engineers and air toxics: citizen participation in technology based standard setting
This article analyses the potential for involving state and local citizen groups in technology-based standard setting for air toxics under the l990 US Clean Air Act. Congress hoped that by focusing on technology rather than risk that the standard setting process would be less contentious. This has not turned out to be the case. There are a number of points where scientists and engineers make ...
U.S. EPA Promulgates Final Air Toxics Standards for Compression Ignition Reciprocating Internal Combustion Engines (RICE)
On March 3, 2010, U.S. EPA promulgated final National Emissions Standards for Hazardous Air Pollutants (NESHAP) for existing compression ignition (CI) stationary Reciprocating Internal Combustion Engines (RICE) that were not previously regulated by the existing, so called, RICE MACT (i.e., 40 CFR Part 63, Subpart ZZZZ). The RICE MACT rule was originally promulgated in 2004. The March 3, 2010 ...

The Difficulties With Attaining Compliance With Environmental Regulations
If you are an environmental compliance manager today with college age children you are probably encouraging them to become dentists or orthodontists, and not to follow in your footsteps as an environmental compliance manager. Arguably one of the toughest positions today is being responsible for managing environmental compliance at an industrial facility. The primary element to managing the ...

The Area Source Mact/Gact Challenge
Dozens of new federal rules, regulating over 180 Hazardous Air Pollutants for relatively small sources, present a new and unique challenge for the air pollution profession. Over the past two decades, a large number of federal regulations have been adopted to control Hazardous Air Pollutants (HAPs) originating from a wide range of source categories from the corner dry cleaner to petroleum ...
Balancing simplicity with accuracy in the use of dispersion modeling in the United States
Dispersion modeling has been a requirement of air quality regulatory agencies in the United States for over 20 years. Over the years, the task of performing this modeling has shifted from the regulatory agency to the applicant. One purpose of the modeling is to show that air quality standards or air toxic guidelines will not be exceeded when the proposed modification or new facility is ...
Fact sheet: EPA mercury rules and power reliability
New rules from the U.S. Environmental Protection Agency to reduce mercury and other toxic air emissions will affect dozens of antiquated power plants currently operating without pollution controls. These rules have stirred debate in some circles as to whether retrofitting or retiring outdated plants will cause shortfalls in electricity capacity. How will EPA mercury rules influence the ...
Controlling Air Pollutants case study
While it's not always easy to determine what's required for compliance, new technologies can help achieve air-pollution control Selecting air-pollution control equipment can be tricky. It's not only difficult to determine which pollutants must be controlled, but also which type of equipment will best control them to required levels for any given process or facility because there is no ...

Air Rule for Cement Kilns Requires 92 Percent Cut in Mercury Emissions
Portland cement kilns will be required to reduce emissions of mercury by 92 percent as part of an Environmental Protection Agency final rule announced Aug. 9 that imposes controls for several toxic pollutants. Although most of the emissions standards in the final rule are less stringent than what the agency had proposed in 2009, the cement industry said the cost to operate the required controls ...

EPA mercury rules: Keeping the lights on while removing toxics from our air
Next week the U.S. Environmental Protection Agency is expected to finalize new rules to reduce mercury and other toxic air emissions that will affect dozens of antiquated power plants currently operating without pollution controls. These rules have stirred debate in some circles as to whether retrofitting or retiring outdated plants will cause shortfalls in electricity capacity. How will new EPA ...
Criteria and Air-Toxic Emissions from In-Use Automobiles in the National Low-Emission Vehicle Program
The U.S. Environmental Protection Agency (EPA) implemented a program to identify tailpipe emissions of criteria and air-toxic contaminants from in-use, lightduty low-emission vehicles (LEVs). EPA recruited 25 LEVs in 2002 and measured emissions on a chassis dynamometer using the cold-start urban dynamometer driving schedule of the Federal Test Procedure. The emissions measured included ...
