  • Is it time to upgrade the PM2.5 federal reference method?

    The fine particulate matter (PM2.5) Federal Reference Method (FRM) has in many respects been a great success. When the method was implemented, there was some doubt that the state and local monitoring agencies that routinely provide air quality data would be able to manage a program, which often distinguishes one location from another by just a few μg/m3. As it turns out, data from the FRM ...

  • Accepted Inspection Methods of Process Sewers.

    During the process of refining there is discharge of hazardous waste, this coupled with aging pipeline infrastructure creates a potential where waste can leak into the environment posing catastrophic threats to life. Federal agencies such as the EPA are beginning to penalize refineries that do not take necessary measures of disposing their waste. These refineries are subject to ...

  • Intercalibration of Fish-based Methods to evaluate River Ecological Quality

    These groups started working immediately and have thus only had 6 months to gather and exchange national data, calculate metric scores and boundaries for national methods and common metrics and compare the results and draw conclusions. This report presents the outcome of the work in the groups and with the common data base. For the common approach at the European level using common metrics, ...

  • Methods of Design and Financing River Restoration Projects Constructed to Address Erosion and Sediment TMDL Problems Resulting from Development in Watersheds

    This paper presents the results of research and experience with design and implementation of creek or river rehabilitation in urban watersheds. The paper discusses a five-step method for designing instream projects for reaches of creek subject to erosion. It recommends a post project audit of design and construction practices to qualify a project as a stream rehabilitation project.The general ...

  • EPA Reviews National Ambient Air Quality Standards for Ozone, and Other Recent CAA Developments

    EPA Reviews National Ambient Air Quality Standards For Ozone: On December 17, 2014, the U.S. Environmental Protection Agency (EPA) issued a proposed rule revising the air quality criteria for ozone (O3) and related photochemical oxidants and National Ambient Air Quality Standards (NAAQS) for O3. 79 Fed. Reg. 75234. EPA proposed to revise the primary standard to a level within ...

  • Performance characterization of the MiniVol PM2.5 Sampler case study

    Measurements were conducted to assess the MiniVol PM2.5 sampler performance for various particle preseparator configurations including flat and cup impaction stages. Laboratory measurements were conducted to determine the impactor collection efficiency as a function of paricle size. Impactor cut points - the aerodynamic particle diameter exhibiting 50% collection efficiency - were 2.5 um (+- 10%) ...

  • Performance-Based Measurement Systems

    Many of the Environmental Protection Agency's (EPA's) methods used to monitor air, water and soil for environmental contaminants prescribe step-by-step details on how the chemical analysis must be conducted and prohibit any deviations or variations. The EPA has recognized that monitoring equipment and technology have improved tremendously over the last few years; that environmental media do not ...

  • Is it clean or contaminated soil? Using petrogenic versus biogenic GC‐FID chromatogram patterns to mathematically resolve false petroleum hydrocarbon detections in clean organic soils: A crude oil spiked peat microcosm experiment

    The Canadian Council of Ministers of the Environment (CCME) Reference Method for the Canada‐Wide Standard (CWS) for Petroleum Hydrocarbons (PHC) in Soil provides chemistry analysis standards and toxicity guidelines for the remediation of contaminated sites. However, these methods can co‐extract natural biogenic organic compounds (BOCs) from organic soils, causing false exceedences of toxicity ...

  • Advanced Water Quality Techniques Course

    Abstract:The development of a strategic water quality monitoring program is based on prioritizing risks to public safety and economic reality. The development of global standardized methods and protocols for automated water quality monitoring would facilitate international communication of water quality information and comparison of standardized methods and protocols. The three primary methods ...


  • Interview with Mary C. McKiel - 2013 Chairman of the ASTM International Board of Directors

    As standards executive for the U.S. Environmental Protection Agency, Mary C. McKiel, Ph.D., brings expertise both in government service and in standards development to her term as 2013 chairman of the ASTM International board. Here she talks about federal use of consensus standards, incorporation by reference and other challenges and opportunities at the intersection of government and standards ...

  • Soft subgrade remedies under heavy axle loads - 2.5-year TTCI test results

    Rapid track geometry degradation can occur under heavy axle loads. Several proposed remedies for this deterioration have been evaluated on the Heavy Tonnage Loop at the Transportation Technology Center, Inc., Pueblo, Colo. A 700-foot-long, soft-subgrade test track, installed in the HTL, provides a nominal track modulus of 2,000-to-2,500 lb/in./in. This section is referred to as the low track ...

  • A dangerous list

    California has proposed Prop 65 Listings under the Labor Code mechanism, but using such listing methods could set a dangerous precedent. On March 4, 2011, the California Office of Environmental Health Hazard Assessment (OEHHA) proposed to list four chemicals as known to the state to cause cancer under the Safe Drinking Water and Toxic Enforcement Act (Prop 65) based on the Labor Code mechanism ...

  • Enhancing Biological Nutrient Reduction in Advanced Individual Onsite Wastewater Treatment Systems

    ABSTRACTAdvanced onsite systems need to continue to improve wastewater treatment through nutrient reduction. Some advanced onsite systems have been shown to reduce nutrients significantly. However, with modifications, these systems can reduce total inorganic nitrogen (TIN) to an even greater degree, and nitrate to levels below federal drinkingwater standards. INTRODUCTIONNitrogen compounds in ...

  • LDAR deficiencies lead to enhanced requirements

    Leak detection and repair (LDAR) programs are required as part of the standards established in 40 Code of Federal Regulations (CFR) 60 (NSPS), 40 CFR 61 (NESHAP), 40 CFR 63 (MACT), and 40 CFR 264 (Hazardous Waste Handling). An LDAR program is a facility’s system of procedures used to locate and repair leaking components (e.g., valves, pumps, connectors, compressors, and agitators) to ...

  • Environmental assessments and audits at aviation facilities

    Environmentalists are all about “green”, but there is another type of green that is associated with being environmentally compliant – money. There are primarily two types of environmental assessments that are performed at aviation facilities that can affect a company’s bottom line: Phase I/II Environmental Site Assessments (ESA) and General Facility Audits. The ESAs are also referred to as due ...
