Coalition for Responsible Waste Incineration



CRWI Update

  April 30, 2010

On April 29, 2010, EPA signed four proposed rules: one to identify non-hazardous secondary materials that are solid waste; a second to propose air toxic standards for industrial boilers and process heaters; a third to propose amendments for commercial and industrial solid waste incinerators; and, fourth, a combined area source rule for industrial boilers and solid waste incinerators. The signed version of the definition of non-hazardous solid waste rule can be found at www.epa.gov/waste/nonhaz/definition.htm. The signed version of the other three can be found at www.epa.gov/airquality/combustion/actions.html. All four should be published in the Federal Register in mid-May. All will have a 45 day comment period and there will be a public hearing scheduled approximately 15 days after the date of publication. A preliminary discussion of three of these proposed rules are below.

Definition of non-hazardous solid waste

On September 22, 2005, EPA revised the definition of “commercial and industrial solid waste” to exclude solid wastes that were being burned for energy recovery. This modification in the definition moved the regulation of units burning solid waste for energy recovery out of section 129 of the Clean Air Act and into section112. In 2007, the US Court of Appeals for the District of Columbia Circuit vacated this rule stating that burning for energy recovery does not override the statutory language requiring that combustion of any solid waste should be regulated under section 129. This created a situation where the units used to develop the MACT standards for both industrial boilers and commercial and industrial solid waste incinerators (CISWI) were in the wrong category, forcing EPA to redo both rules. In addition, EPA had to re-examine how non-hazardous solid waste is defined under RCRA so they could decide which category to put these units into when developing the next set of MACT standards. Basically, those units that burn non-hazardous secondary materials that are a solid waste will be regulated under Section 129 and those that burn secondary materials that are not solid wastes will be regulated under Section 112.

This proposed rule will significantly increase the current universe of non-hazardous secondary materials that are identified as solid waste, pushing more units into the 129 arena. The proposed rule assumes that all non-hazardous secondary materials are a solid waste unless:
  • It is used as a fuel that remains within the control of the generator (whether at the site of generation or another site the generator has control over) and it meets the legitimacy criteria;
  • It is used as an ingredient in a manufacturing process (whether by the generator or a third party) that meets the legitimacy criteria;
  • Discarded non-hazardous secondary material has been sufficiently processed to produce a fuel or ingredient that meets the legitimacy criteria; or
  • When, through a case-by-case petition process, it has been determined that material handled outside the control of the generator has not been discarded and is indistinguishable in all relevant aspects from a fuel product.
The proposed rule also requests comment on several other approaches which may further narrow the universe of “non-waste” materials including an approach that would identify all non-hazardous secondary materials burned in combustion units to be solid wastes. The key to which materials fit into which category appears to be based on a plain-English meaning of the term “discard.” In a 1987 ruling (American Mining Congress vs. EPA), the Appeals Court stated that “discard” means “disposed of,” “thrown away,” or “abandoned.” The court went on to say that “discard” could not include materials destined for beneficial reuse or recycling.

CISWI proposed rule

The proposed amendments to the commercial and industrial solid waste incinerator (CISWI) rule are written under the authority of Section 129 of the Clean Air Act. EPA is proposing to divide the CISWI universe into five subcategories: incinerators; energy recovery units; waste burning kilns (including cement kilns); burn-off ovens; and small, remote incinerators. They are proposing to remove the startup, shutdown, and malfunction provisions currently in the regulations and require facilities to be in compliance with the standards at all times. EPA is also proposing to change the monitoring requirements. For example, any existing unit that has a fabric filter will be required to install a bag leak detection system, existing kilns will be required to monitor mercury emissions using a continuous emissions monitoring system (CEMS), existing energy recovery units will be required to monitor carbon monoxide using a CEMS, and if the energy recovery unit has a design capacity of greater than 250 MMBtu/hr, a PM CEMS would be required. EPA specifically asked for comments on whether these CEMS should be applied to other subcategories. EPA used a straight emissions approach to select the top performers and a 99% upper limit to set the standards. This is the same approach as used to set the standards for the hospital/medical/infectious waste incinerator MACT rule. The proposed standards (corrected to 7% oxygen) for existing sources are as follows.

HAP Incinerator Energy recovery units Waste burning kilns Burn-off ovens Small rural incinerators
HCl (ppmv) 29 1.5 1.5 130 150

NOx (ppmv) 34 130 1100 120 210
SO2 (ppmv) 2.5 4.1 410 11 44

Boiler proposed rule

The industrial boiler proposed rule is being developed under the authority of Section 112 of the Clean Air Act. EPA is proposing to regulate five pollutants: particulate matter (PM); hydrochloric acid (HCl); mercury; carbon monoxide (CO); and dioxin/furans (D/F). PM is used as a surrogate for all metals except mercury, CO is used as a surrogate for non-dioxin organic hazardous air pollutants, and HCl is used as a surrogate for acid gases. EPA has divided the category into eleven subcategories. These are shown in the table below. EPA is proposing that coal, biomass, or residual oil units that have a design heat capacity of 250 MMBtu/hr or greater be required to install and operate PM CEMs. EPA is also proposing to require CO CEMs for all units that have a design heat capacity of 100 MMBtu/hr or greater. Facilities with CO CEMs are required to meet the standards using a 30-day rolling average. The proposed rule will require facilities to meet the standards at all times, including startup, shutdown, and malfunctions. EPA used a straight emissions approach to select the top performers and a 99% upper prediction limit (UPL) to set the standards. This is a slightly different approach than was taken in the CISWI rule. The UPL is a statistic designed to predict whether the facility will pass the next test. This statistic also tends to give lower numbers than does an upper limit (used to set the CISWI standards). It is interesting that the Agency used two different statistical methods to develop standards for these two rules. The proposed standards (D/F standards are corrected to 7% oxygen, CO standards are corrected to 3% oxygen, the rule is silent on the other three standards) for existing sources are as follows.

Fuel Unit PM (lb/mm Btu) HCl (lb/mm Btu) Hg (lb/mm Btu) CO (ppmv) D/F TEQ (ng/dscm)
Coal Pulverized 0.02 0.02 0.000003 90 0.004

Stoker 0.02 0.02 0.000003 50 0.003

Fluidized bed 0.02 0.02 0.000003 30 0.002
Biomass Stoker 0.02 0.006 0.0000009 560 0.004

Fluidized bed 0.02 0.006 0.0000009 250 0.02

Suspension burner/Dutch oven 0.02 0.006 0.0000009 1010 0.03

Fuel cell 0.02 0.006 0.0000009 270 0.02

Gas Other gas 0.05 0.000003 0.0000002 1 0.009

It should be noted that EPA choose not to set numerical standards for the new and existing natural gas and refinery gas boiler subcategories. Instead, they choose to set a work practice standard that requires an annual tune up. They are also proposing a work practice standard (annual tune up) for all existing sources that have a design heat capacity of 10 MMBtu/hr of less. In addition, EPA is proposing that all major sources conduct an energy assessment to identify cost-effective energy conservation measures.

TRI additions

On April 6, 2010, EPA proposed to add 16 chemicals to the list of toxic chemicals subject to reporting under section 313 of the Emergency Planning and Community Right-to-Know Act. All sixteen have been classified as “reasonably anticipated to be a human carcinogen” by the National Toxicology Program. A list of the chemicals can be found in the Federal Register notice. Comments will be accepted until June 7, 2010.

Case-by-case MACT comment period extended

On April 29, 2010, EPA extended the comment period for the proposed rule to amend the way the Agency handles case-by-case MACT emission limits under section 112(j) of the Clean Air Act. Comments will now be accepted until May 27, 2010.

PC MACT

The Portland cement industry is urging EPA to recognize that the natural variability of mercury concentrations in limestone should be considered when setting the floor standards. Other observers have suggested that this idea has already been considered and rejected by the courts. In the middle of all of this is an effort by industry to postpone the June 6, 2010, deadline for signing the final rule until December so that additional data can be collected to support these ideas. Industry maintains that the current recession and severe winter has made it difficult to gather the data necessary to support their position. Industry is also arguing that EPA should have conducted a risk-risk analysis of this rule. This idea is that reducing one risk raises another risk.

Region 5 and 8 Administrators named

President Obama selected Susan Hedman to be the next Regional Administrator for Region 5. Ms. Hedman has been the environmental counsel for the Illinois Attorney General since 2005. Prior to that, she was a senior policy advisor on energy and recycling at the Illinois Department of Commerce and Economic Opportunity, a staff attorney for the Environmental Law & Policy Center, and the research director for the University of Maryland Center for Global Change. One the same day, President Obama announced that James Martin had been selected to be the Regional Administrator for Region 8. Mr. Martin most recently was the Executive Director of Colorado’s Department of Natural Resources. Prior to that, he was the Executive Director of Colorado’s Department of Public Health and Environment and managed a non-profit organization that focused on energy, public lands, and water issues.

Climate change – legislation

Senators John Kerry (D-MA), Joe Lieberman (I-CT), and Lindsey Graham (R-SC) scheduled the release of their climate change bill for April 26, 2010. There was considerable optimism that this bill would contain sufficient compromises to allow for passage of climate change legislation this Congress. Then Senate Majority Leader Harry Reid (D-NV) decided that the Senate needed to take up immigration reform sooner rather than later. Senator Graham does not believe that immigration reform can pass in the Congress and decided that if the Democrats were not willing to put a priority on climate change legislation, he would withdraw his support. As such, no new legislation has been introduced. During the same time period, several “disasters” occurred that will have an impact on any energy legislation. There was an explosion in a West Virginia coal mine that killed 29 miners. There was an explosion on an offshore oil rig that killed 11 people and is currently releasing large amounts of oil into the Gulf of Mexico. Sierra Club took this opportunity to point out the need to move away from “dirty, dangerous, and deadly energy sources.” While it probably a little too early to declare any climate change legislation dead, the political decision to push immigration reform and the two explosions will certainly make it harder to develop compromise legislation.

Climate change – regulations

On April 12, 2010, EPA proposed four different actions adding to or modifying the current reporting requirements for green house gas emissions. One was to modify the mandatory greenhouse gas reporting rule to require facilities to provide the name, address and ownership status of their U.S. parent company; their primary and all other applicable North American Industry Classification System code(s); and an indication of whether any of their reported emissions are from a cogeneration unit. In the second, EPA proposed to revise the greenhouse gas reporting requirements for fluorinated greenhouse gas emissions from electronics manufacturing, the production of fluorinated gases, and the use of electrical transmission and distribution equipments. In the third, EPA proposed to require reporting of greenhouse gas emissions from onshore petroleum and natural gas production, offshore petroleum and natural gas production, natural gas processing, natural gas transmission compression stations, underground natural gas storage, liquefied natural gas storage, liquefied natural gas import and export terminals, and distribution. In the fourth, EPA is proposing a rule to require reporting of carbon dioxide injection and geological sequestration. Comments on all four proposed rules will be accepted until June 11, 2010.

At a John Hopkins University forum on climate change, Gina McCarthy, EPA Assistant Administrator for the Office of Air and Radiation, stated that the Agency should have guidance for the states on what constitutes best available control technology (BACT) for greenhouse gases by the end of 2010. She indicated that there were a number of options on the table and that none of them have been eliminated. She stated that fuel switching has never been required by the Agency and that BACT is generally applied to the design of the facility.

After the 2007 Supreme Court decision requiring EPA to make an endangerment finding for greenhouse gases, environmental groups challenged a Prevention of Significant Deterioration (PSD) permit for a new electric generation unit in Utah, claiming that the court ruling required regulation of greenhouse gases based on an interpretation of “subject to regulation.” This was taken before the Environmental Appeals Board, which remanded the permit back to the agency stating that there was insufficient historical, binding interpretation of what “subject to regulation” meant. On December 18, 2008, then EPA Administrator Stephen Johnson issued a memo explaining EPA’s position that “subject to regulation” covered only those pollutants that require actual control of emissions and does not apply to pollutants whose emissions are simply monitored. What this meant was that simply asking a facility to monitor and report emissions did not trigger a requirement to limit emissions of those pollutants in a PSD permit. Environmental groups filed a petition for reconsideration, stating that this action did not follow the proper notice and comment process. EPA granted that petition and proposed a number of ways to interpret the phrase. On April 2, 2010, EPA published their responses. Basically, they came to the same conclusion that “subject to regulation” is meant to include “each pollutant subject to either a provision in the CAA or regulation adopted by EPA under the CAA that requires actual control of emissions of that pollutant.” The bottom line is that until EPA sets emissions limits for greenhouse gases, PSD permits cannot require any limits on greenhouse gas emissions. While that seems like a logical conclusion, it will prevent the use of PSD permits as a method for setting greenhouse gas emission limits for new facilities. However, this is a short-term victory because EPA is already in the process of developing emission limits for greenhouse gases.

Finally, a New Mexico judge agreed that the state’s Environmental Improvement Board does not have the authority to set limits on greenhouse gas emission without first establishing ambient air quality standards for these pollutants. This ended a petition by environmental groups to reduce state greenhouse gas emissions by 25% below 1990 levels by 2020.

Environmental Justice

As a part of the settlement with the Rosewood Neighborhood Association complaint (see the March Update), EPA was required to compile a list of complaints received. Since 1994, EPA’s Office of Civil Rights (OCR) has received 300 complaints. More than 130 were rejected on jurisdictional grounds and 15 were dismissed on merit. None of these found any discrimination that would trigger sanctions. OCR continues to investigate 30 claims including 12 jurisdictional claims. Jurisdictional claims are supposed to be decided within 20 day of receipt. These 12 claims were received between January 2009 and March 2010. In addition, OCR is still investigating the first complaint it received, agreeing in January 1995 to investigate a petition filed in July 1994. Part of the problem is a struggle to settle on a legally defensible definition of what constitutes “disproportionate impact.” Disproportionate impact refers to policies that are seemingly neutral on the surface but in effect, discriminate on a minority population. Some of these problems are complex and sensitive, making it difficult to come up with a single policy that works for all situations.

In addition, OCR has failed to file annual reports with the Equal Employment Opportunity Commission for 2006, 2007, and 2008. These reports (known as MD 715) detail an agency’s internal affirmative employment and disability program plans. They include identifying problems in their hiring practices and showing how they are being corrected. The MD 715 for 2009 was filed on March 31, 2010.

For the first time, a historically black community has won the right for a hearing. Ironically, it was not part of the U.S. judicial system but from the Inter-American Commission on Human Rights of the Organization of American States (OAS). The Advocates for Environmental Human Rights (AEHR) filed a petition on behalf of the residents of Mossville, LA with OAS in 2005. On March 30, 2010, OAS agreed to hear the case over the strong objections of the U.S. government. The petition alleges that existing laws fail to recognize or remedy the significant pollution burden of pollutants released by 14 different industrial facilities in Mossville. AEHR has been asking the Department of Justice to address this complaint since 1996 and viewed the OAS petition as an option of last resort. AEHR stated that they did not file a petition with EPA’s OCR because of the office’s reputation for inaction.

CRWI meeting

The next CRWI meeting will be in San Francisco on May 17, 2010, in conjunction with the IT3 conference. The technical meetings will concentrate developing initial comments on the recently proposed boiler MACT, CISWI MACT, and definition of non-hazardous solid waste rules.
