  • Mobile Stationary Source Emissions Testing, Coming to a Facility Near You?

    Last week, Antea Group had the unique opportunity to perform a RATA (relative accuracy test audit) of the emissions from a thermal oxidizer at an ethanol production facility located in Minnesota using a state-of-the-art mobile testing laboratory. During this RATA audit, actual stack emissions levels (including NOx, SOx, CO2, CO, O2, flow rate, temperature, velocity and pressure) from the ...

  • Reducing Odor and VOC Emissions

    The Montgomery County Regional Composting Facility (MCRCF) in Silver Spring, Maryland is designed to process 400 wet tons/day of lime amended biosolids from the Blue Plains Wastewater Treatment Plant (WWTP) in Washington, D.C. Recently, political pressures forced operations to cease at the MCRCF. Although the aerated static pile composting plant’s fate has not been completely decided, its owner, ...

  • Modeling emissions from offshore drilling

    To regulate drilling activities proposed by oil and gas companies in the oil-rich Gulf of Mexico (GOM), governing agencies require the submittal and approval of certain plan documents before drilling activities can be initiated. For drilling activities in the Western GOM, these plans typically consist of one of the following: EP, or Exploration Plan – required to conduct ...

  • A cure for Environmental Emissions case study

    Disposing of nearly 1 million pounds of medical waste a month is no easy task. The wet electrostatic precipitator, installed at Rochester, MN-based Mayo Clinic, seems to be just what the doctor ordered. While the medical waste incinerator at Mayo Clinic in Rochester, MN, consistently met state and federal emission requirements, facility leadership recognized that installing a wet electrostatic ...

  • Grana-Localized Proteins, RIQ1 and RIQ2, Affect the Organization of Light-Harvesting Complex II and Grana Stacking in Arabidopsis

    Abstract Grana are stacked thylakoid membrane structures in land plants that contain photosystem II (PSII) and light-harvesting complex II proteins (LHCIIs). We isolated two Arabidopsis mutants, reduced induction of non-photochemical quenching (riq1 and riq2), in which stacking of grana was enhanced. The curvature thylakoid 1a curt1a) mutant was previously shown to lack grana structure. ...

  • Analyzing Stack Gas Semivolatiles, Using Supelpak-2 Adsorbents and Capillary GC (Modified Method 5, US EPA SW-846)

    The demanding detection limits required for air sampling by Modified Method 5 (US EPA SW-846, Method 0010) necessitates extensive cleaning and meticulous handling of the adsorbent cartridge/trap during sampling and analysis. Supelpak-2 adsorbent is cleaned in accordance with and meets the purity criteria of EPA SW-846, Method 0010, for testing semivolatile emissions from incinerator stationary ...

  • In-situ continuous emissions monitoring & regulatory compliance

    As environmental scrutiny has risen and regulation has tightened in recent years, the importance of having accurate information on the environmental performance of your power plant has increased. After all, if you want to manage something, you need to be able to measure it. The analogy is obvious; you wouldn't start a diet without first investing in a set of scales. So it is with Continuous ...

  • Sensitivity of AERMOD in Modeling Fugitive Dust Emission Sources

    Dispersion modelers have long faced challenges estimating ambient pollutant concentrations caused by releases from “fugitive” sources of particulate matter, such as paved and unpaved roadways, raw material storage piles, outdoor material processing operations, agricultural activities, or windblown dust in general. Fugitive emissions are commonly defined as those that could not ...

  • Mayo finds technical fix to reduce incinerator emissions

    While the medical waste incinerator at Mayo Clinic in Rochester, Minn., consistently met state and federal emission requirements, facility leaders wanted to find a way to go beyond these standards. Mayo Clinic’s medical waste incinerator serves Mayo Clinic, Saint Marys Hospital and Rochester Methodist Hospital, which form the largest group medical practice in the world, and processes 2,000 ...

  • New laser-based dust emission monitoring system

    Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...

  • Proposed boiler MACT sets aggressive emission limits

    On June 4, 2010, U.S. EPA proposed National Emission Standards for Hazardous Air Pollutants (NESHAP) for industrial, commercial, and institutional boilers and process heaters at both major and area sources of hazardous air pollutants (HAP) emissions.  EPA proposed separate rules for units at major sources of HAP emissions (greater than 10 tons per year [tpy] of any single HAP and/or greater ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

  • Sources of PCDDs/PCDFs In Cement Kiln Emissions

    Abstract This paper presents data on the source of PCDDs/PCDFs in cement plant stack emissions, demonstrating that these emissions are not necessarily all created by the process. The data potentially demonstrates that some of the PCDDs/PCDFs in the emissions are pre-existing dioxins and furans that are vaporized out of the kiln raw feed. This calls into question the assumption that PCDD/PCDF ...


  • Infrared differential absorption Lidar (DIAL) measurements of hydrocarbon emissions

    We report the application of an infrared (IR) differential absorption Lidar (DIAL) system (also capable of ultra violet measurements) built at the National Physical Laboratory (NPL), UK, to field measurements of total site emissions (controlled and fugitive) from petrochemical and landfill installations. The validation of the IR-DIAL was carried out via a series of controlled field experiments ...

  • Incineration Industry: Scrubber on Sludge Incinerator Reduces Atmospheric Emissions Case Study

    Aberdeen Sewage Treatment Plant in Aberdeen, Washington started up their new Electric Infrared Incinerator in May, 1981. The sewage sludge incinerator, product of Shirco, Inc., needed a pollution control device in order to meet state, local and federal requirements for atmospheric emissions, according to the emissions test on the unit performed January, 1982. Chosen was a Model 24×24- ...
