More and more, we are talking about trace level ambient monitoring. This monitoring is in line with the measurement objectives of NCORE which is part of the Ambient Monitoring Technology Information Center of the US EPA. According to the EPA website, "NCore is a multi pollutant network that integrates several advanced measurement systems for particles, pollutant gases and meteorology. Most NCore stations have been operating since the formal start of the network on January 1, 2011." The measurement standards, as set it 40 CFR Part 58 Appendix A, are:Read More

On October 1, 2017, a new ozone standard took effect in the US amid widely differing opinions. In late 2014, the EPA had proposed lowering the ozone standard to a between 65 to 70 from the current standard of 75 ppb (set in 2008 under the Bush administration). Public discussion was heated with many groups urging the EPA to maintain the existing standard. On October 1, 2015, under a court-ordered deadline, the EPA finalized the ozone National Ambient Air Quality Standard (NAAQS) standard at 70 ppb.Read More
Several Air Force bases in the United States have recently unveiled their new Reduced Oxygen Breathing Devices (ROBD). The ROBD simulates altitude exposure and can be utilized for both research and training purposes. The U. S. Armed Forces use the ROBD 2 to train aircrew to recognize the signs and symptoms of hypoxia and to perform the appropriate emergency procedures. Congratulations to these sites on their new facilities!Read More
This week, the US House of Representative's Committee on Energy and Commerce Subcommittee discussed H.R. 806, known as the Ozone Standards Implementation Act of 2017. HR 806 was introduced on February 1, 2017 by Pete Olson, the Representative for Texas's 22nd congressional district and cosponsored by Mr. Flores, Mr. Latta, Mr. Bishop of Georgia, Mr. McCarthy, Mr. Cuellar, Mr. Scalise, Mr. Costa, Mr. Cramer, Mr. Long, Mr. Jenkins of West Virginia, Mr. Burgess, Mr. Renacci, Mr. Hensarling, Mr. McKinley, Mr. Guthrie, Mr. Bucshon, Mr. Johnson of Ohio, Mr. Weber of Texas, and Mr. Babin.Read More
This week, the US House of Representative's Appropriations Subcommittee held hearings to discuss President Trump’s 2018 budget request for the EPA. Newly appointed EPA Administrator Scott Pruit testified before the subcommittee regarding the proposed 30% cut to the EPA budget and the impact this might have both in terms of funding for various projects as well as the workforce reduction. The hearing lasted about two hours, with Representatives from both parties asking Administrator Pruitt questions about the cut. The main focus was the impact such cuts would have on the local and regional air, water and land pollution protection/cleanup programs that exist within their districts.Read More
Today, the US EPA released the 2015 data under the Greenhouse Gas Reporting Program. The report details the sixth year of greenhouse gas pollution trends from large industrial sources.
Overall, reported emissions decreased by almost 5% percent from 2014, and 8.2 percent from 2011. The more than 8,000 large sector facilities contribute about half of the total Greenhouse Gas emissions annually.Read More
As we end the summer, this year is expected to be the hottest on record for the second year in a row. Climate change is on the forefront of President Obama's mind in his final months in office. Last week, he delivered paperwork commiting the US to reduce their emissions of greenhouse gas pollution to about a quarter below the levels from 2005 by 2025. Likewise, China , the leading producer of greenhouse gas, has committed to a halt in emissions by 2030. A large part of this decrease has been attributed to the reduction in coal consumption.Read More
The US EPA announced on Monday that a notice of violation, or NOV, of the Clean Air Act was issued to Volkswagen. The EPA states that the model years 2009-2015 Volkswagen and Audi vehicles (4-cylinder diesels) included software that allowed the cars to evade some emissions standards.Read More
On June 2, following an announcement by President Obama, the US EPA presented the Clean Power Plan, "a commonsense plan to cut carbon pollution from power plant" with the stated goal of maintaining "an affordable, reliable energy system" while reducing pollutants that are harmful to people as well as the environment."
Throughout the US, power plant emissions account for roughly one-third of greenhouse gas emissions. Currently, there are no national guidelines to limit carbon pollution levels, though the levels of other toxins, including arsenic, mercury, sulfur dioxide, nitrogen oxides, and particles, are restricted. In the US, CO2 emissions account for 82% of all green house gas emisions, according to data reported by the EPA from 1990-2012.
Although the mandate is set at the federal level, the guidelines give states the ability to establish their own internal goals and to design a program based on their specific needs and capabilities. These plans must be submitted to the EPA by June 2016. Each state's plan must have enforceable limits, and must include how the levels will be reported and monitored. There must also be a method for corrective actions for those who fall short. The EPA will require biannual reporting of the state's progress.
Once the plan is accepted, states have to reach interim goals by 2020 and have until 2030 to meet the final goal of a 30% decrease in carbon emissions from the levels reported in 2005. To put that in perspective, that is equal to the emissions from powering 65 million homes, roughly half of the homes in America.
In addition to the 30% reduction in carbon emissions, the Clean Power Plan will also result in the reduction of particle pollution, nitrogen oxides, and sulfur dioxide by more than 25 percent. Consumers should also benefit from a roughly 8 percent decrease in their electric bills due to increased energy efficiency and reduced demand in the electricity system.
