Coalition for Responsible Waste Incineration



CRWI Update

  June 30, 2010

Boiler/CISWI proposed rules

The four proposed rules (boiler MACT, area source boiler, commercial and industrial solid waste incinerator (CISWI), and the definition of non-hazardous solid waste) were published in the Federal Register on June 4, 2010. The original comment period was for 45 days and closed on July 19, 2010. On June 9, 2010, EPA extended the comment period for another 15 days. The new deadline for comments is August 3, 2010.

On June 23, 2010, 27 entities sent a letter to EPA Administrator Lisa Jackson requesting a further extension of the comment period for the four proposed rules. The 27 entities are mostly industry trade organizations but also includes municipal electric generation facilities in Ohio. The basis for the request is that 60 days is not enough time to adequately develop comments on four major rules that have an impact on a large segment of industry. The letter states that even though EPA made the proposed rules available approximately a month prior to the official publication date, most critical support documents (including MACT floor analyses) were not put into the docket until the proposed rule was actually published. In fact, some of the supporting spreadsheets for the rule were not put in the docket until late June. The letter points out several serious errors in the data base (e.g., using a conversion from total dioxin to toxic equivalents twice resulting in significantly lower proposed standards, misclassification of sources, etc.), the large number of regulated units being impacted by this rule, and that other MACT rules have had longer comment periods. The letter also points out that the “court ordered deadline” is a deadline that EPA willingly accepted and can be re-negotiated. In fact, EPA has already done that at least once for these rules. In sum, the letter claims that industry cannot properly respond to all four proposed rules in the time allotted and requests an additional 90 days. EPA has not yet responded to the letter and it is difficult to predict how they will respond. Given the volume of comments they are likely to receive, the number of errors in the data base, and the number of sources in the wrong categories, the Agency may have trouble getting the data base corrected by the current December deadline, let alone getting the final rule written.

PC MACT

The Portland cement (PC) MACT will be going to the Office of Management and Budget (OMB) in the next couple of weeks for a final review before being signed on August 6, 2010 (as now required under the court deadline). The Portland Cement Association (PCA) is gearing up for one final push to both the Agency and OMB. In addition to direct advocacy to OMB, PCA is hoping to get other federal agencies (primarily the Federal Highway Administration) to assist them based on the idea that this rule will force an estimated 30 plants to close rather than upgrade to meet the standards. This would reduce the domestic clinker production by 27 million metric tons (approximately 20%) and potentially increase imports of Portland cement. PCA is urging EPA to add subcategories for high and low mercury content in the limestone used, subcategories for whether the emissions of an in-line coal mill are commingled or not, and urging EPA to allow the use of a health-based alternative standard for hydrochloric acid. If EPA finalized the rule as proposed, expect PCA to challenge the final rule for using a HAP-by-HAP approach that results in no sources being able to meet the standards, the failure to include provisions for startup, shutdown, and malfunctions, requiring hydrochloric acid CEMs to show compliance when the standards were developed from stack test data, and developing a MACT-on-MACT standard for PM.

Formaldehyde

On June 2, 2010, EPA announced the availability of an external review draft human health assessment entitled Toxicological Review of Formaldehyde Inhalation Assessment: In Support of Summary Information on the Integrated Risk Information System (IRIS) (EPA/635/R-10/002C). This draft document finds a causal link between formaldehyde exposure and several types of cancer and raised the upper bound lifetime unit risk to 1.1 X10-4 per microgram per cubic meter for three cancer types (nasopharyngeal cancer, Hodgkin lymphoma, and leukemia) but acknowledges that the mechanism for causing such cancers is unknown. This revised estimate is about 10 times higher than the current upper bound lifetime risk. In the press release for this document, EPA stated that this change would make formaldehyde a “national risk driver.” Any change in the cancer risk will have an immediate effect on the plywood industry but it could quickly reach other industry sectors. EPA states that this change will impact a number of industry sectors, including motor vehicles, power plants, manufacturing facilities that use glues, petroleum refineries, coking operations, incineration, and wood burning. EPA recently required boilers and power plants to test for formaldehyde emissions as a part of a Clean Air Act 114 request. While they did not use this data to set proposed MACT standards for this pollutant for boilers, they now have data on formaldehyde emissions from various combustion sources. EPA will hold a listening session on the draft assessment on July 27, 2010, in Arlington, VA. The comment period will close on August 31, 2010.

ECF rule withdrawn

On June 13, 2010, EPA officially withdrew the emissions comparable fuels (ECF) rule. This rule was originally published in December 2008 in the last days of the Bush Administration. The environmental groups sued, arguing that this rule illegally allows companies to avoid stringent hazardous waste regulations. In May, 2009, the Obama Administration announced that it would withdraw this rule in response to the lawsuit. The official reason is that EPA has concluded that ECF materials are more appropriately classified as discarded materials and should be regulated as hazardous wastes. The exclusions for comparable fuels and synthetic gases promulgated in 1998 are not impacted by this action.

Coal combustion residual proposed rule

On June 21, 2010, EPA proposed to regulate coal combustion residuals from electric utilities and independent power producers. Comments will be accepted until September 20, 2010. Additional details can be found in the May 2010 Update.

Tank labeling withdrawn

In March, EPA published a direct final rule making a number of technical changes to correct or clarify several RCRA regulations. CRWI and others pointed out that some of these changes were not corrections but made substantive changes in the way facilities complied with the regulations. On June 4, 2010, EPA withdrew the following four changes:
  1. The change to 40 CFR 262.34(a) that related to the hazardous waste accumulation time for large quantity generators;
  2. The change to 40 CFR 262.34(a)(2) that related to the date upon which each period of accumulation begins must be clearly marked and visible for each container and tank;
  3. The change to 40 CFR 262.34(a)(5) that related to the closure requirements for tanks, containers, drip pads, and containment buildings; and
  4. The change to 40 CFR 266.20(b) related to recyclable materials used in a manner constituting disposal.
Basically, all four changes were removed and the rules revert back to where they were prior to the March 18, 2010, direct final rule.

Audit program for Texas flexible permits

On June 17, 2010, EPA Region 6 offered holders of Texas flexible air permits the opportunity to participate in a voluntary compliance audit program intended to identify federally enforceable Clean Air Act emission limitations, operating parameter requirements, and monitoring, reporting, and recordkeeping requirements for all units covered by flexible permits. The program does not eliminate the possibility of civil penalties as a result of the audits but hints at methods for bringing the units into permanent compliance with the federal standards and the appropriate resolution of any civil penalties. As a part of this notice, EPA states: “It is important to emphasize that although participation in this Audit Program is voluntary, participants who successfully complete the program will receive appropriate covenants in resolution of noncompliance.” In another place, they state: “Nothing in this notice should be read to preclude EPA from taking enforcement action where it determines such action is appropriate to address non-compliance.” Environmental groups have expressed concern that the program will allow facilities to avoid liability for past responsibilities.

Meanwhile, the Texas Commission on Environmental Quality (TCEQ) proposed changes in their flexible permits program to address EPA’s concerns. The modifications would add a specific reference to federal standards such as best available control technology, add a requirement for applicants to determine federal new source review (NSR) applicability, modify the language making it clear that facilities may not use flexible permits to avoid NSR requirements, and adding a requirement to demonstrate that any new permit or modification to an old permit would not interfere with attainment of national ambient air quality standards. TCEQ will take comments on these proposed changed until August 2, 2010. Given the proposed changes in the flexible permits program, it is difficult to see where many facilities will take advantage of EPA’s audit program.

Six risk assessments to be reviewed

EPA has relied upon a number of studies conducted by the Ramazzini Institute (Bologna, Italy) as a part of their risk assessments for certain chemicals. Industry groups have protested using these studies stating that their protocols differ significantly from those used by American laboratories. The Ramazzini Institute protocol exposes the animals to the chemical in question for the life of that animal. American laboratories tend to expose for a specific time period and sacrifice the animal. As an animal ages and dies, there is a certain amount of disintegration of the cells (especially after death) that may not be related to the exposure to the chemical but is a natural part of aging and death. When the National Toxicological Program (NTP) reviewed slides from the Ramazzini Institute methanol study, they found a lower incidence of lymphoma or leukemia than did the Ramazzini scientists. Essentially, NTP scientists classified a number of the lesions as inflammatory lesions rather than as cancer lesions. As a result, EPA is putting a hold on the draft assessments for methanol, methyl tertiary butyl ether, ethyl tert-butyl ether, and acrylonitrile until the differences between the two interpretations can be resolved. In addition, EPA will review their assessments for vinyl chloride and 1,1-dichloroethylene that were completed in 2000 and 2002, respectively, because these assessments were based in part on Ramazzini Institute data.

PAH assessments

In February, EPA proposed to use relative potency factors to estimate the cancer risks for mixtures of polycyclic aromatic hydrocarbon (PAH) mixtures. EPA’s Science Advisory Board convened a special panel on June 21-23, 2010, to examine this concept. The panel stated that the draft document failed to demonstrate an adequate scientific basis for choosing a relative potency factor approach for PAH’s. However, after a lengthy debate, the panel agreed that the relative potency factor idea was the most pragmatic short-term approach available but that EPA should only use it in the interim while working on a more complex mixture-driven approach. The panel also suggested developing 12 – 15 different mixtures most commonly found and using them in in vivo tumor studies to check the accuracy of the approach. In addition, the panel suggested additional cancer bioassay data was needed to validate the approach. Finally, the panel agreed that benzo(a)pyrene was the most logical choice as the index chemical because EPA has the most data for this compound.

Dioxin

In May, EPA released its draft report entitled Reanalysis of Key Issues Related to Dioxin Toxicity and Responses to NAS Comments. The comment period for this report originally ended on August 19, 2010. In response to request, EPA has extended the comment period another 30 days. The comment period now ends on September 20, 2010. Details can be found in the June 23, 2010, Federal Register notice.

Climate change – legislation

On June 10, 2010, Senate Joint Resolution 26 failed on a 47-53 vote. This resolution was authored by Senator Lisa Murkowski (R-AK) and, if passed, would have disapproved the EPA rule finding that greenhouse gases endanger human health and the environment. Getting this resolution passed by both Houses of Congress and signed by the President was a long shot, at best. However, opponents of the endangerment finding were able to keep all Republicans and get six Democrats to support the Resolution.

Meanwhile, the President held a bipartisan meeting with two dozen Senators in an effort to move climate and energy legislation. Democrats came out of the meeting indicating a willing to compromise on the current Kerry-Lieberman draft but stopped short of endorsing an energy-only approach. Republicans advocated taking any national energy tax (cap-and-trade with a price on carbon emissions) off the table during a recession. Others suggested that the carbon limit should only apply to electric generations units. However, there does not seem to be any consensus on what should be included or excluded. With Congress in session for only a couple of weeks before the August recess and mid-term elections looming in November, it may be difficult for them to come to any resolution until after the election. Depending on how many incumbents lose, anything is possible during the post-election sessions.

Climate change – regulations

On June 28, 2010, EPA Administrator Lisa Jackson signed a final rule expanding the greenhouse gas emissions reporting requirements to include underground coal mines, magnesium production facilities, industrial waste landfills, and industrial wastewater treatment plants. These four new source categories will be required to start collecting emissions data on January 1, 2011 with their first report due on March 31, 2011.

The greenhouse gas tailoring rule was published on June 3, 2010. On June 4, 2010, the Southeastern Legal Foundation filed a petition for review with the US Court of Appeals for the District of Columbia Circuit challenging the legality of this rule. They were joined in the suit by 14 House Republicans.

Case-by-Case MACT

Sierra Club has been trying to prevent EPA from issuing a Title V operating permit for the Hugh L. Spurlock power plant in Maysville, KY for a number of years. Their latest effort is a notification of intent to sue unless the Agency responds to their petition that the current permit is illegal because it does not contain a case-by-case determination for reducing emissions of hazardous air pollutants. Sierra Club claims that the MACT “hammer” provision of the Clean Air Act requires EPA to set case-by-case emissions standards for a category after a court has vacated the sector-wide MACT standards. Since the court vacated the cap-and-trade mercury rule (Clean Air Mercury Rule), the Sierra Club contends that EPA and Kentucky must now use the hammer provisions to set site-specific emission standards for arsenic, beryllium, cadmium, chromium, dioxins, hydrogen chloride, lead, and mercury. Not only will the outcome of this litigation impact the rest of the electric generation category, it could also apply to all other MACT rules that have been vacated (industrial boilers, brick kilns, and polyvinyl chloride production).

Clean Harbors – Kimball fine

Early in June, EPA Region 7 and Clean Harbors signed a consent agreement and final order resolving allegations resulting from inspections by EPA in 2007 and Nebraska in 2008. These inspections found several open, unlabeled and leaking containers, storage of different wastes in proximity that could cause a chemical reaction, failure to minimize the potential of release of hazardous waste to the environment, failure to make hazardous waste determination on two containers, failure to ensure the integrity of a secondary containment structure, failure to properly manage a container of received waste, and improper emissions control for certain hazardous waste tanks. Clean Harbors had already installed additional control devices on the hazardous waste tanks. Clean Harbors also agreed to submit plans for minimizing the potential release of hazardous wastes and for addressing cracks and gaps in the secondary containment structure. In addition, Clean Harbors agreed to pay a $150,000 civil penalty.

CRWI meeting

The next CRWI meeting will be in Elyria, Ohio on August 3-4, 2010. The preliminary agenda will include discussions of the state of the art for PM and mercury CEMs. For more information, contact  CRWI.
