Carbon capture and storage (“CCS”) is the process of capturing carbon dioxide emissions from large point sources, and then transporting it to a storage location for deposit in underground formations where it will not re-enter the atmosphere.  By returning CO2 emissions that resulted from the


New projects require air permits and projects at major stationary sources that will emit (or increase) a significant amount of a regulated NSR pollutant, must conduct a control technology review.  In order to receive a permit, the applicant must determine the level of control considered Best Available Control Technology (“BACT”) and the permit issuing authority


EPA is required by Section 109(d) the Clean Air Act to review the adequacy of each National Ambient Air Quality Standard (“NAAQS”) every five years to determine if new scientific evidence justifies a change to the standard.  The current primary[i] NAAQS for nitrogen dioxide (“NO2”) is 53 ppb annual mean and 100 ppb NO2 as


On March 2, 2017, the EPA withdrew its information collection request (ICR) regarding methane emissions from existing oil and gas facilities.  EPA finalized and issued the underlying ICR on November 10, 2016.  Since that time, EPA sent letters to thousands of owners and operators in the oil and gas industry, requiring them to complete surveys


The Environmental Protection Agency (EPA) announced in March that it is in the process of developing new regulations to curb methane emissions from existing oil and gas facilities.  The EPA will formally require companies operating existing oil and gas sources to provide information to assist in the development of comprehensive regulations to reduce methane emissions.  


President Obama’s centerpiece of his climate policy agenda, the “Clean Power Plan,” has become one of the most heavily litigated environmental regulations ever. Twenty-seven states and numerous industry groups have filed more than fifteen separate lawsuits challenging the Environmental Protection Agency’s (“EPA”) statutory authority to promulgate the regulations.   Seventeen states, the District of Columbia, the


On May 15, 2014, the Environmental Protection Agency (“EPA”) announced that it intended to publish a proposed rule to amend the national emission standards governing petroleum refineries. [1]  The emission standards impacted by this proposed rulemaking are:

  • National Emission Standards for Hazardous Air Pollutants (“NESHAP”) from Petroleum Refineries (40 CFR part 63, subpart CC) (Refinery

On July 28, 2011, the Louisiana Department of Environmental Quality (LDEQ) denied a petition for the adoption of a rule to regulate fossil fuel carbon dioxide (CO2) emissions and to establish an effective emissions reduction strategy that will achieve a concentration of 350 parts per million (ppm) atmospheric CO2 by the year 2100. The petition was filed on May 4, 2011, by Kezia Kamenetz, of New Orleans, and Kids vs Global Warming, a non-profit organization formed in Oak View, California.

As of July 3, 2011, the air quality measured at the official ozone monitor at 1425 Airport Drive, which is within Shreveport, but located in Bossier Parish, indicated that the design value for the parish is now 76.7 parts per billion (ppb) which exceeds the 75 ppb standard set by EPA in 2008. 40 C.F.R. §50.15. The design value for each monitor is the 3 year average of the 4th highest ozone reading at that monitor each year. The exceedance of the current standard will likely cause the Louisiana Department of Environmental Quality (LDEQ) to propose that EPA designate Bossier Parish, and perhaps Caddo and DeSoto Parishes, as an ozone nonattainment area.

LDEQ was required to submit its recommendation for nonattainment designations under the 2008 ozone standard by March 12, 2009. EPA was then required to act on the proposals and make final designations no later than March 12, 2010. 73 Fed. Reg. 16436, 16503 (Mar. 27, 2008). In its 2009 recommendation, LDEQ did designate Caddo, but not Bossier or DeSoto, parishes as nonattainment. (1) However, when air quality in Caddo parish improved to compliance status over the past several years, LDEQ amended that recommendation in January 2010 to classify Caddo as attainment. (2)

New major and modified existing stationary sources require air permits prior to beginning construction. Where increases of criteria pollutants  such as sulfur dioxide, nitrogen dioxide, carbon monoxide, particulate and volatile organic compounds exceed a “significance” threshold, the permittee is required to analyze available and technically feasible control technology with the goal of selecting the best available control technology (BACT) for new or modified emissions units. With agency agreement, the selection of BACT becomes an enforceable part of the permit. 

We now have a new “pollutant,” greenhouse gas (“GHG”) equivalents for the six regulated greenhouse gases (carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, perfluorocabons, and hydrofluorocarbons). GHGs are measured as equivalents to carbon dioxide, the most common GHG (CO2e). Starting January 2, 2011, permits issued for facilities that otherwise trigger PSD (as above) and have a new or increased potential to emit (PTE) of CO2e of 75,000 TPY, must address GHG emissions. Following July 1, 2011, a PSD permit may be required for significant increases in GHGs alone (100,000 tpy for a new source or 75,000 tpy for` a modification), even where there is no significant increase of any other regulated criteria pollutant. 

As with other pollutants, once PSD is triggered for GHGs, the permittee must evaluate and propose that which constitutes BACT to control the CO2e. Although the general scheme for selecting BACT is familiar, a top down ranking of available and technical feasible technologies, the available options are not. There are no conventional CO2e scrubbers or waste heat boilers, or filter traps to capture CO2e.  While some technologies are emerging, the process of determining BACT for CO2 control is a new frontier, and lack of guidance can cause permitting delays. To address some of the uncertainties,  EPA issued guidance on November 10, 2010 concerning permitting GHGs explaining the process for determining the required emission control technology – BACT.
