HWC MACT

In the October 18, 2007, Federal Register, EPA announced that the comment period for the “legal analysis” would be extended until November 27, 2007. As a result, EPA filed an unopposed motion with the court to move their next reporting date from December 5, 2007, to February 29, 2008. At that time, EPA will have made their final decisions on which standards to defend and which to re-do.

In the September 27, 2007, notice, EPA made it clear that it was their intention to remand any standards that are to be re-done. However, at least one trade group will argue for vacating these standards. Whether their arguments will convince EPA to change their minds has yet to be seen. The other major decision that EPA will need to address in the February 29, 2008, report to the court is whether to keep the litigation together or split it into two parts. The way EPA has this process currently structured, one group of standards will be revised and the other left alone. For the standards that are to be revised, the court will have no interest in reviewing these standards since they are not “final decisions.” However, for the standards EPA is not planning to change (including the incinerator standards and the health based alternative standard for chlorine), the court may consider these as “ripe” for review. The environmental groups will likely argue that the litigation should be split and the litigation for the standards that have not been changed should go forward and the only parts that should be delayed are the ones that EPA is going to change. Other parties (including EPA) may oppose this, arguing that the issues have a number of things in common and should all be decided at one time. If the latter view prevails, the second litigation of the HWC MACT rule may not take place until 2012. If the former view prevails, parts of the second HWC MACT litigation could go forward in 2008 and the other parts may wait until 2012. It could certainly get interesting if the courts were to remand/vacate one part of the rule while EPA is redoing another part.

Plywood MACT

On June 19, 2007, the Appeals Court vacated two provisions of the Plywood MACT. On October 29, 2007, EPA published a direct final rule implementing the court mandate; changing the compliance date for this rule from October 1, 2008 to October 1, 2007 and removed the regulatory language creating and delisting the low risk subcategory. Since this action was simply fulfilling the court’s mandate, EPA decided it was not necessary to go through the proposal process. This action became effective on the date it was published. It is interesting that EPA has not published similar notices removing the vacated parts of the Brick MACT or industrial boiler MACT regulations.

EPA Enforcement Priorities

In an October 12, 2007, Federal Register notice, EPA announced their national enforcement and compliance assurance priorities for fiscal years 2008, 2009, and 2010. For air toxics, the office will focus on problem areas in leak detection and repair (LDAR), industrial flares, and surface coatings. The surface coating group has 14 MACT standards. During the 2005-2007 time period, EPA evaluated more than 40 MACT standards, identified these three areas as national priorities because there were high levels of non-compliance. This was attributed to a lack of understanding of the regulatory requirements, failure to adhere to the requirements, and failure to operate control devices according to manufacturer’s specifications. Additional details can be found in the notice.

EPA Enforcement

EPA announced two large enforcement actions during October. On October 9, 2007, American Electric Power (AEP) agreed to reduce sulfur dioxide and nitrogen oxide emissions by 813,000 tons, pay a $15 million penalty, and spend an additional $60 million on projects to mitigate the effects of past emissions. They estimated that the cost for the equipment to reduce sulfur dioxide and nitrogen oxide emissions would be $4.6 billion. This agreement covers 16 facilities in five states. The settlement resolves a lawsuit filed against AEP in 1999 alleging violations of the new source review provisions of the Clean Air Act.

On October 25, 2007, EPA announced an agreement with BP North America that included criminal fines for violations in Texas and Alaska and an agreement to spend $400 million on safety upgrades and improvements to prevent future spills. The criminal fines included $50 million for the explosion at their Texas City refinery that killed 15 people. In addition, the company pleaded guilty to a felony violation of the Clean Air Act and will serve three years on probation for the incident. They will also be required to complete a facility wide study of their safety valves and renovate their flare system to prevent excess emissions. In Alaska, the company will pay a $12 million criminal fine for spilling 200,000 gallons of crude oil on the Alaska tundra. BP pleaded guilty to one misdemeanor of the Clean Water Act and will serve three years probation for this spill. In addition, BP will be required to replace 16 miles of pipeline.

Despite this, Democrat leadership in Congress remains concerned that EPA enforcement is still inadequate. Responding to a Washington Post article, Representative John Dingell (D-MI) and Bart Stupak (D-MI) sent a letter to EPA Administrator Steve Johnson asking why more was not being done. The Washington Post article alleged that the Agency failed to initiate criminal prosecutions in other investigations even though they were clearly merited. Since Mr. Dingell is the Chairman of the House Energy and Commerce Committee and Mr. Stupak is the Chairman of the oversight subcommittee of that committee, the Administrator will have to take these questions seriously. In addition, Mr. Dingell and Mr. Stupak have questioned why the settlements with AEP and BP were only fines and did not include jail time for company executives.

TCEQ Adopts Phase II Standards

The Texas Commission on Environmental Quality (TCEQ) has announced the intention to incorporate, by reference, all of the amendments to the HWC MACT rule (subpart EEE) since 2005. This includes the replacement standards and the Phase II standards promulgated on October 12, 2005, the April 20, 2006 amendment revising compliance during startup, shutdown, and malfunction events, and the October 26, 2006, amendment suspending the new source PM standard for cement kilns. TCEQ expects this rule to be published on November 23, 2007, with an effective date of December 2, 2007.

Residual Risk Litigation

EPA promulgated their residual risk determination for organic hazardous air pollutions from the synthetic organic chemical manufacturing sector in December 2006. This rule is often called the HON (hazardous organic NESHAP) rule. The Natural Resources Defense Council (NRDC) and the Louisiana Environmental Action Network (LEAN) promptly challenged this rule. In their opening briefs, submitted to the court on September 12, 2007, the environmental groups made three main arguments.
  1. EPA failed to follow the plain language of the statute when they failed to promulgate additional standards where the risks were greater than 1-in-a-million.
  2. EPA failed to review and revise all MACT standards every 8 years as required under section 112(d)(6).
  3. EPA used incomplete, unverified, and non-representative data when conducting the risk assessments.
In Section 112(f)(2)(A) of the Clean Air Act Amendments of 1990, the statutory language states that if the original MACT standards do not reduce the risk to below 1-in-a-million, EPA has to promulgate additional standards for that category to further reduce the risks. However, in the next section of the Clean Air Act (112(f)(2(B)), Congress also indicated that EPA could use the Benzene NESHAP as a model when promulgating residual risk rules. Under the Benzene NESHAP model, if the risk is less than 1-in-a-million, no additional action is needed. If the risk is greater than 100-in-a-million, some regulatory action to reduce the risk is required. In between these two numbers, the Agency can consider other factors (including cost) in deciding whether to impose additional standards. Thus, Congress appears to have given EPA conflicting instructions on how to do residual risk. EPA has chosen to use the benzene NESHAP as a model rather than the plain language of 112(f)(2)(A). In challenging this rule, the environmental groups have asked the court to decide what Congress meant.

Section 112(d)(6) requires EPA to review and revise all MACT standards “as necessary” every eight years “taking into account developments in practices, processes, and control technologies.” In the final rule, EPA stated that they found no significant developments in practices, processes, or control technologies and as such, would not require any additional standards under 112(d)(6). In their brief, the environmental groups argue that this language requires EPA to redo the MACT floors every eight years. Since EPA did not do this, they ask the court to tell EPA to go back and reset the floor every eight years. If the court agrees, this would require EPA to ratchet down MACT standards every eight years.

Finally, the environmental groups argue that EPA should not have relied upon data submitted by the industry to determine the residual risk. Instead, EPA should have issued a Clean Air Act section 114 information request to gather the data necessary to calculate residual risk for every facility in the category.

EPA will file their brief in November, defending their actions. It is too early in the process to guess which side will win. However, the stakes for industry are quite high. This ruling will set the precedent for all subsequent residual risk rules (including the HWC MACT rule).

Dioxin

In July 2006, the National Academy of Sciences (NAS) released a highly critical review of EPA’s 2003 draft risk assessment of dioxin. The report listed a series of alternative approaches to assessing cancer risk and suggested downgrading EPA’s classification from ”carcinogenic to humans” to “likely to be carcinogenic to humans.” In addition, the NAS panel suggested setting a non-cancer exposure limit (reference dose) and to examine the overall assessment’s uncertainty. EPA is planning to release a work plan in November that will describe how the Agency will respond to the NAS review. Observers expect that the responses will come out piecemeal and will not be available in any form for at least a year. EPA is currently looking for expertise outside the Agency to do part of the work. It looks like the process that was started in 1991 will take a few more years to complete.

Non-Linear Risk Models

EPA’s cancer risk guidelines, revised in 2005, recommend the use of a linear model to extrapolate risk from the last know value to zero. However, the guidelines also allow the use of a non-linear model if the data shows that a non-linear response is more appropriate. Both ways can be used to estimate the risk of exposure for the areas between the lowest measured exposure and zero exposure. Some members of the scientific community believe that “one molecule can result in cancer” but others believe that there is no scientific evidence to support that belief. Ethylene oxide is the first compound to be evaluated under the new guidelines. The draft assessment proposes to tighten the 1985 exposure threshold of 3.6 ppb to 0.06 ppt, based on a linear model. Preliminary reports from a Science Advisory Board panel reviewing the draft indicate that the panel will recommend that the agency should use both a linear and a non-linear model to assess the risks at low doses. Several panel members believe a non-linear model would be more appropriate because carcinogens that are mutagenic do not have a linear relationship with exposure. It is unclear how EPA will respond to these suggestions by the panel. It is quite interesting that both the National Academy of Sciences and the Science Advisory Board are pushing the Agency to consider the use of non-linear models to estimate risks at low exposures.

PCB Program Transferred

On October 9, 2007, EPA published a final rule that moved the management of the PCB cleanup program and most of the PCB disposal program from the Office of Prevention, Pesticides, and Toxic Substances to the Office of Solid Waste and Emergency Response (OSWER). This will not change the cleanup and disposal programs within the Agency. It simply changes the office that is overseeing the program. Any current agreements remain in place but all new agreements must be submitted to OSWER. The notice also amends 40 CFR parts 750 and 761 to account for this change in responsibility.

Climate Change

Early in October, Congressmen John Dingell (D-MI) and Rick Boucher (D-VA) released the first of a series of climate change white papers. This paper contains a mixture of recommendations and a list of issues for further discussions centered on a cap-and-trade program. The paper concludes that the United States should reduce greenhouse gas emissions by 60 to 80 percent by 2050. To do this, the United States should adopt an economy wide, mandatory program. While the white paper argues that the program should cover all facilities that emit greenhouse gases, it goes on to outline exemptions for such small sources as residential use of natural gas, heating oil or coal. While more than 350,000 facilities emit carbon dioxide from burning fossil fuel, 47,000 emit more than 1,000 tons of carbon dioxide per year, and about 8,000 of these sources emit more than 10,000 tons of carbon dioxide per year. This information will be used to help decide the threshold for which facilities are covered. Alternatively, the paper discusses whether the point of regulation should be the fossil fuel itself, rather than the stack of the impacted facilities. This paper and the ones to be released in the future will be the basis for legislation in the House of Representatives. While there are several other climate change bills that have already been introduced in the House, the Dingell-Boucher bill will be the one that will be moved though the House Energy and Commence Committee and on to the floor of the House. A copy of this paper can be found on the committee web site (energycommerce.house.gov).

On the Senate side, Senators John Warner (R-VA) and Joe Lieberman (I-CT) introduced the America Climate Security Act (S 2191). It is co-sponsored by five Democrats and 4 Republicans. This bill is designed to reduce greenhouse gas emissions in the United States by 70 percent by 2050. It covers any source that emits more than 10,000 tons of carbon dioxide equivalents per year. Residential and commercial boilers and space heaters are not covered by the bill. The bill will set up a cap-and-trade program and set the number of tons of carbon dioxide equivalents that can be released per year (one allowance is 1 metric ton of carbon dioxide equivalents). The number of allowances is set at 5.2 billion in 2012 and will reduce by 1.8 percent per year until 2050 when the number of allowances will be 1.56 billion. The Climate Change Credit Corporation will auction 18 percent of the allowances in 2012. The percentage will increase to 73 percent in 2050. The rest will be distributed to the industrial sectors based on a fixed percentage outlined in the legislation. The bill also starts a series of rulemakings, surveys, and technical reviews for developing a national infrastructure for geological sequestration. It also contains provisions for biological sequestration. The Chairwoman of the Senate Environment and Public Works Committee, Senator Barbara Boxer (D-CA), has indicated that she plans a markup of this bill in subcommittee in early November. She hopes to have it out of the full committee by the end of this year.

Activists continue to push for carbon dioxide limits on power plants. Sierra Club filed a petition with EPA’s Environmental Appeals Board asking that the permit for a Utah coal fired power plant be sent back to the Agency because it does not include carbon dioxide emission limits. There have also been challenges to existing and pending permits for coal-fired power plants in New Mexico, Illinois, and Nevada. All of these challenges are a direct result of the Supreme Court decision that carbon dioxide is a pollutant under the Clean Air Act. Once that designation is made, these groups argue that each permit must include a section on what is the best available control technology (BACT) for that pollutant when applying for a permit. Since none of these permits did this, they should be returned to the Agency for additional work. In addition, the Kansas Department of Health and Environment rejected an air permit for a proposed coal-fired generating plant because its carbon dioxide emissions would harm the environment. EPA continues to have the position that it must first develop regulations for mobile sources before they can address carbon dioxide emissions from stationary sources. They also point out that putting permit limits on carbon dioxide emissions prior to developing regulations would violate the Administrative Procedures Act and would not be legal.

EPA announced that they plan to propose regulations in the summer of 2008 to govern the geological sequestration of carbon dioxide. The regulations will be written under the authority of the Safe Drinking Water Act by the underground injection control program. This program currently regulates how fluids can be injected into underground formations.

Phthalates

Governor Arnold Schwarzenegger has signed legislation that will ban in California the use of phthalates in toys and other products designed for children under the age of three. The ban will take effect in 2009. Senator Dianne Feinstein (D-CA) has indicated she will pursue a similar federal ban but has not provided any details or timetables.

Dow Corning Gasification Unit

On October 1, 2007, Dow Corning broke ground on a gasification unit that will take 660 tons of liquid chlorinated organic waste per year and convert it to aqueous hydrochloric acid and synthetic natural gas. Dow expects the unit to produce about 200 pounds per hour of HCl and 10.5 MBtu/hr of syngas. The unit will also produce about a third of the facility’s steam needs. The HCl will be re-used in the manufacturing process and the syngas will be used to replace about 400 billion Btu per year of natural gas. Dow Corning states that this will be the first plasma-based processing system used to recycle chemical wastes in the United States. Veolia Environmental Services has a 10-year contract to operate the facility. Operations are expected to begin by the end of 2008.

CRWI Meeting

The next CRWI meeting will be held on November 8-9, 2007, in Chantilly, VA. The major item on the agenda will be how to respond to EPA’s decisions on the HWC MACT rule. For additional information, please contact  CRWI.
