Acid Rain Program Database Updated

Saturday, December 5th, 2009

The Acid Rain Program (ARP) Database is updated with Third Quarter 2009 data. The database provides unit-level information available from US EPA Clean Air Markets Data and Maps. Information includes unit type, fuels used, air pollution control devices installed, as well as links to files containing Continuous Emission Monitoring System (CEMS) information and unit emissions data.

Final Mandatory Reporting of Greenhouse Gases Rule

Thursday, September 24th, 2009

On September 22, 2009 US EPA issued the Final Mandatory Reporting of Greenhouse Gases Rule. The rule requires reporting of greenhouse gas (GHG) emissions from large sources and suppliers in the United States. The rule is intended to collect accurate and timely emissions data to inform future policy decisions.

Under the rule, suppliers of fossil fuels or industrial greenhouse gases, manufacturers of vehicles and engines, and facilities that emit 25,000 metric tons or more per year of GHG emissions are required to submit annual reports to EPA. The gases covered by the proposed rule are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFC), perfluorocarbons (PFC), sulfur hexafluoride (SF6), and other fluorinated gases including nitrogen trifluoride (NF3) and hydrofluorinated ethers (HFE).

Part 75 Emissions Monitoring Policy Manual

Monday, July 27th, 2009

US EPA has posted a Draft Part 75 Emissions Monitoring Policy Manual. The draft addresses January 24, 2008 amendments to 40 CFR Part 75 and the conversion of the Clean Air Markets Division data systems to the Emissions Collection and Monitoring Plan System (ECMPS).

US House of Representatives passes the American Clean Energy and Security Act (ACES)

Friday, June 26th, 2009

The US House of Representatives narrowly passed a bill aimed at capping and reducing US greenhouse gas emissions and lowering the country’s dependence on foreign oil. Some reports in the press:

US EPA has assessed the economic implications of policies to reduce the greenhouse gas intensity of the US economy, and has provided an overview of the economic analyses and the modeling tools and methods used. In addition, there is information on long term scenarios of climate related economic impacts and non-CO2 greenhouse gases:

US EPA Emission Measurement Documents

Thursday, June 4th, 2009

US EPA has posted updated versions of documentation for Clean Air Markets continuous emission monitoring systems (CEMS). These revised versions reflect the transition to the Emissions Collection and Monitoring Plan System (ECMPS), the January 24, 2008 revisions to 40 CFR 75, and the 2008 Court decisions regarding the Clean Air Interstate Rule (CAIR) and Clean Air Mercury Rule (CAMR) regulations.

In addition, the Office of Air Quality Planning and Standards (OAQPS) has posted a summary of recent projects:

PDF document OAQPS Measurement and Monitoring Projects. March 2009 (pdf, 15pp., 53kB)

And, a revised list of US EPA test methods has been posted:

US EPA CEM Presentations

Wednesday, May 27th, 2009

US EPA has posted presentation materials for the recent EPRI CEM Users Group Conference on their website. Topics included: greenhouse gas (GHG) reporting, mercury (Hg) monitoring, and information on Clean Air Markets (ARP, NBP, and CAIR).

Proposed Mercury Emission Regulations for Cement Plants

Tuesday, April 21st, 2009

US EPA is proposing mercury emission regulations for portland cement manufacturers. In addition to mercury, the changes would add or revise emission limits for hydrochloric acid (HCl), total hydrocarbons (THC), and particulate matter (PM).

Also inculded in the proposed amendments are performance specifications for mercury continuous emission monitors (CEMS), as well as updated recordkeeping and testing requirements:

  • Performance Specification 12A—Specifications and Test Procedures
    For Total Vapor Phase Mercury Continuous Emission Monitoring
    Systems in Stationary Sources.
  • Performance Specification 12B – Specifications and Test
    Procedures For Monitoring Total Vapor Phase Mercury Emissions
    from Stationary Sources Using a Sorbent Trap Monitoring System
  • Procedure 5. Quality Assurance Requirements for Vapor Phase
    Mercury Continuous Emission Monitoring Systems Used for
    Compliance Determination at Stationary Sources

Combustion Gas Periodic Monitoring Protocol

Thursday, April 9th, 2009

South Coast Air Quality Management District (SCAQMD) has posted a draft final source test protocol for Rules 1110.2, 1146, and 1146.1. The protocol is for the periodic monitoring of nitrogen oxides (NOx), carbon monoxide (CO), and oxygen (O2) from combustion sources. The protocol has been developed to ensure standardization of test procedures, and includes specifications for test conditions, test methods, test equipment, data collection/reporting, and quality assurance procedures.

Previously, SCAQMD posted a protocol for compliance testing:

Proposed Amendments for Particulate Matter Measurements

Wednesday, March 25th, 2009

The US Environmental Protection Agency (US EPA) has proposed amendments to methods for measurement of filterable fine particulate (Method 201A) and measurement of condensable particulate matter emissions from stationary sources (Method 202). The proposed amendments to Method 201A would add a particle-sizing device to allow for sampling of particulate matter (PM) with mean aerodynamic diameters less than or equal to 2.5 micrometers (PM2.5 or fine PM). The proposed amendments to Method 202 would revise the sample collection and recovery procedures of the method to reduce the formation of reaction artifacts that could lead to inaccurate measurements of condensable particulate matter (CPM).

Predictive Emission Monitoring Systems in Stationary Sources

Tuesday, March 24th, 2009

The US Environmental Protection Agency (US EPA) has finalized criteria for facilities to determine if predictive emission monitoring systems (PEMS) can be used instead of continuous emissions monitoring systems (CEMS). These evaluation criteria are known as Performance Specification 16—Specifications and Test Procedures for Predictive Emission Monitoring Systems in Stationary Sources. PEMS predict source emissions indirectly using process parameters that have a known relationship to pollutant concentration.

US EPA is allowing, but not requiring, facilities to predict their emissions in
compliance with the following rules:

  • Standards of Performance for Industrial-Commercial-Institutional Steam Generating Units (40 CFR Part 60); and
  • Standards of Performance for Stationary Gas Turbines (40 CFR Part 60).

In addition, a number of facilities regulated by state and local agencies are considering their use. The rule also amends several testing and monitoring provisions to make minor clarifications and corrections, including the use of portable analyzers for quarterly relative accuracy audits.
