Boiler/CISWI rules

The four proposed rules (industrial boiler and process heater, commercial and solid waste incineration, area sources, and definition of non-hazardous solid waste) are all scheduled for publication in the Federal Register for June 4, 2010. It is not clear why these rules have taken over a month (signed on April 29, 2010) to get published. It may simply be the logistics of publishing four large proposed rules on the same day. The comment periods for all four are currently 45 days. Industry groups are gearing up to ask for additional time to develop comments. It is also rumored that the environmental groups are also considering asking for additional time based on their opposition to the proposed work practice standards for gas fired boilers instead of numerical standards. EPA may grant additional time but is likely to couple any extension with an extension of the court ordered deadline for a final rule (now at December 16, 2010). However the timing plays out, these proposed rules will have a significant impact on the costs of industry to comply. As such, the number of industries and industry groups cooperating to oppose these proposed standards is unusual.

HMIWI amendment

On May 14, 2010, EPA proposed to change the existing source NOx standards and the new source SO2 standards for the large subcategory of the Hospital/Medical/Infectious Waste Incineration (HMIWI) rule. The reason for these two changes is that EPA inadvertently used the incorrect statistics. For both, EPA originally used a normal distribution. After further examination, they determined that a log-normal distribution should have been used. EPA recalculated the standards and is proposing to revise the existing source NOx standard for Large units from 130 ppmv to 140 ppmv and the SO2 standard for new Large units from 1.6 ppmv to 8.1 ppmv. EPA is also proposing to correct three cross-references to 60.56c(d), (h), and (j). The comment period for this proposed amendment closes on June 28, 2010.

Dioxin

On May 21, 2010, EPA announced the availability of its draft report entitled Reanalysis of Key Issues Related to Dioxin Toxicity and Responses to NAS Comments. Even though the draft report is almost 2000 pages long, it does not appear to address all the 2003 comments made by the National Academy of Sciences panel. In the draft report, the cancer slope factor (CSF) increased from 1.5 E+05 mg/kg body weight/day to 1.0 E +06 mg/kg/day. The new CSF is based on all cancer mortality from the NIOSH cohort. EPA continues to use a linear method stating there is insufficient evidence to support a non-linear (threshold) model. In addition, EPA will for the first time establish an oral reference dose (RfD) of 0.7 pg/kg/day. The value is based on two epidemiology studies on semen quality and thyroid hormone levels in populations with significant exposure in Seveso, Italy. This value incorporates a factor of 10 to convert from lowest observed adverse effect level to no observed adverse effect level and a factor of 3 to account for human variation. This level is less than the 1-4 pg/kg/day established by the World Health Organization.

If cancer slope factor remains at 1.0 E +06 in the final report, it would mean increased estimated dioxin risks when doing human health risk assessments (HHRA). Whether existing HHRAs would need to be redone is not yet known. Adding the RfD will bring in the bigger question of the safety of the world’s food supply. The Science Advisory Board will hold a public meeting on July 13-15, 2010, to discuss this draft and EPA will accept comments on the document until August 19, 2010.

CCR proposed rule

On May 4, 2010, EPA signed a proposed rule to regulate coal combustion residues (CCR) under RCRA. EPA is proposing two options on managing CCR. One would require reversing the Bevill determination for CCR destined for disposal and to list it as a special waste under RCRA Subtitle C. These materials would be regulated from the point of generation to the point of final disposal. This would include generator and transporter requirements and requirements for managing CCR (including siting, liners, run-on and run-off control, groundwater monitoring, fugitive dust control, financial assurance, corrective action, and closure and post-closure care). Facilities that dispose of, treat, or store CCR would be required to obtain a Subtitle C permit for these units. The proposed rule would also regulate the disposal of CCR in sand and gravel pits as landfills. Existing surface impoundments will also require liners, with strong incentives to close impoundments and transition to landfills that store coal ash in a dry form. The proposed regulations will ensure stronger oversight of the structural integrity of impoundments in order to prevent accidents. They are also proposing to prohibit the disposal of CCR below the natural water table.

The second option proposed would leave the Bevill determination in place and would place CCR under RCRA Subtitle D with national criteria for the surface impoundments or landfills. New units would be required to install composite liners. Existing units would be required to be retrofitted with liners within five years or close. Both new and existing units would have groundwater monitoring and corrective action requirements for releases from the units, closure and post closure requirements, and requirements to address the stability of surface impoundments. This option would also regulate disposal in sand and gravel pits as landfills. EPA is asking for comments on financial assurances needed under this option. This option would not require permits nor would EPA be able to enforce the requirements. This would be left to states and citizen suits. EPA proposes one modification of this option where existing units would not have to retrofit but could continue to operate through their useful life.

EPA is carefully not to indicate which of the two options they prefer (going so far as to label them co-options and not even listing them as options A and B). The estimated costs to industry for the Subtitle C option is higher than the Subtitle D option but the estimated benefits are also much higher, resulting in a benefit/cost ratio for the two options being about the same. A copy of the signed rule can be found at www.epa.gov/epawaste/nonhaz/industrial/special/fossil/ccr-rule/index.htm. The proposed rule will have a 90-day comment period once published in the Federal Register (expected in mid-June).

GHG tailoring rule

On May 13, 2010, EPA Administrator Lisa Jackson signed the greenhouse gas tailoring final rule. This rule was made necessary because of the 2009 finding that greenhouse gases are “reasonably anticipated to endanger the public health and welfare of current and future generations.” The endangerment finding set off a cascade of events to regulate greenhouse gas emissions from mobile and stationary sources. Without the tailoring rule, PSD (prevention of significant deterioration) and Title V permitting requirements would apply to all stationary sources that emit or have the potential to emit more than 100 or 250 tons of greenhouse gases per year starting on January 2, 2011. EPA determined that this would greatly increase the number of required permits, impose an undue cost on small sources, overwhelm the resources of the permitting authority, and severely impair the functioning of the existing programs. The tailoring rule is designed to relieve these burdens by phasing in the applicability of these requirements over time, starting with the largest emitters. EPA is basing this final rule on three legal doctrines: 1) the “absurd results” doctrine which authorizes agencies to apply statutory requirements different from a literal reading when a literal reading would lead to absurd results; 2) the “administrative necessity” doctrine which authorizes agencies a way to apply the requirements to avoid impossible administrative burden; and 3) the “one-step-at-a-time” doctrine that authorizes agencies to implement regulations in steps.

The final rule sets up a three step process. The first step will begin on January 2, 2011 where PSD or Title V requirements will apply to a source’s greenhouse gas emissions only if a source is already subject to PSD or Title V due to non-greenhouse gas emissions. In this step, the applicable requirements of PSD (best available control technology – BACT, which has not yet been defined for greenhouse gases) will apply to sources that increase net greenhouse gas emissions by at least 75,000 tons per year of carbon dioxide equivalents but only if the project also significantly increases emissions of at least one non-greenhouse gas pollutant. For the Title V program, only existing sources with (or new sources applying for) Title V permits for non-greenhouse gas pollutants will be required to address greenhouse gas emissions. Step two will begin on July 1, 2011, and will phase in additional large sources of greenhouse gas emissions. New or existing sources not already subject to step one that emit or have the potential to emit 100,000 tons per year of carbon dioxide equivalents will now become subject to the PSD and Title V requirements for greenhouse gas emissions. Step three will phase in additional sources by July 1, 2013. EPA has not decided how to do this but has committed to rulemaking to be completed by July 1, 2012, to describe this process.

It is very likely that the legal authority for this rule will be challenged. In fact, the Southeast Legal Foundation has stated that they plan to challenge the rule as soon as it is published. They will base this challenge on the idea that EPA does not have the authority to modify a statute, even if it is helpful to small businesses. It is unclear if others will join them in this challenge once the rule is published. This rule is scheduled for publication in the June 3, 2010, Federal Register.

Greenhouse gas BACT

Because the tailoring rule is final, EPA must develop guidance by January 2, 2011, for the states on how to implement BACT for greenhouse gases. Based on what was presented to their Clean Air Act Advisory Committee, the soon-to-be-released draft guidance will offer advice but not much in terms of concrete direction. There is currently a lot of uncertainty as to what will be considered and what will be eliminated. About the only general themes currently discussed are efficiency and fuel switching. EPA has not come to terms with how to quantify efficiency in stationary sources and has not made up their mind on whether to use fuel switching as BACT. Industry proposed that biomass fuels be exempt because they were “carbon neutral.” For the time, EPA appears to have rejected this idea. The committee members have stated that the short time allowed for the process will eliminate most of the out-of-the-box ideas and will restrict them to what has already been presented. EPA is developing a database on greenhouse gas mitigation strategies starting with cement plants and electric generation units. EPA plans to release a series of white papers summarizing technical options on a sector specific basis. Sectors include cement manufacturing, electric generation units, refining, iron and steel making, pulp and paper mills, industrial boilers, and nitric acid plants. In most cases, it appears that EPA’s advice will focus on the existing top-down pattern for BACT review. At this stage, it appears that EPA will offer little help while pushing the burdens to implement this to the states.

Region 6 proposes to deny TCEQ SSM provisions

In 2006, Texas Commission on Environmental Quality (TCEQ) proposed in their state implementation plan to allow facilities an affirmative defense for civil penalties for excess emissions during startup, shutdown, and malfunction (SSM) events. EPA reviewed that request and determined that the proposal was inconsistent with the Clean Air Act as interpreted in EPA policy and guidance. As a result, EPA Region 6 proposed to deny that request on May 13, 2010. EPA will accept comments on this proposed action until June 14, 2010.

In addition, EPA Region 6 has decided to bar the use of a TCEQ flexible permit for the Flint Hills East refinery in Corpus Christi, TX because they believe that the flexible permit would violate the Clean Air Act. Region 6 will now write the permit for this refinery and potentially several others unless TCEQ changes their program.

PBDE exposure assessment

On May 24, 2010, EPA announced the availability of the final report entitled An Exposure Assessment of Polybrominated Diphenyl Ethers (EPA/600/R-08/086F). The report provides an estimate of the exposure of Americans to polybrominated diphenyl ethers (PBDE). A copy of the report can be found at www.epa.gov/ncea.

IRIS - hexachloroethane

On May 13, 2010, EPA announced a 60-day comment period and a public listening session for the draft document entitled Toxicological Review of Hexachloroethane: In Support of Summary Information on the Integrated Risk Information System (IRIS) (EPA/635/R-09/007). The listening session will be held on June 16, 2010, in Arlington, VA. The comment period closes on July 12, 2010.

DQA petitions

The Data Quality Act (DQA) was passed as a rider on the 2001 consolidated appropriations bill. It instructed the Office of Management and Budget (OMB) to create guidelines under the Paperwork Reduction Act to develop information resource management procedures for reviewing and substantiating the quality of any agency’s information before it is disseminated. The Act requires that the guidelines “ensuring and maximizing the quality, objectivity, utility and integrity of information (including statistical information) disseminated by the agency.” The Act also requires that OMB develop a mechanism where affected persons can seek and obtain correction for information disseminated by an agency that does not comply with these guidelines. On February 22, 2002, OMB published those guidelines. Basically, the guidelines require all federal agencies to ensure that data used to develop policy are objective, reproducible, and peer-reviewed and that petitions to correct allegedly flawed data are accepted and responded to. Environmental groups have opposed the implementation of these requirements, stating that they are simply ways to delay agency actions. These guidelines were not extensively used until recently. Industry has argued that data incorporated into the recent IRIS draft assessments for the risks of trichloroethylene in drinking water were not properly peer reviewed. On the proposed targets for cleaning up dioxin contaminated soils, industry submitted comments that the data used to develop the clean-up levels do not follow DQA guidelines. It is expected that industry will continue to use this tool in challenging data used for setting new policies and standards.

RICE rule challenge

A coalition of energy companies has filed a petition in the U.S. Court of Appeals for the District of Columbia Circuit (May 3, 2010) asking for a judicial review of the reciprocating internal combustion engine (RICE) rule. The coalition has not yet announced what issues they will be challenging. When the RICE rule was published (March 3, 2010), environmental groups expressed concern that the rule used carbon monoxide as a surrogate for organic hazardous air pollutants and that it did not set numerical emission standards during startup. It is not clear whether any of the environmental groups also filed petitions.

Climate change – Legislation

Senators John Kerry (D-MA) and Joseph Lieberman (I-CT) released their climate change bill on May 12, 2010. As released, the bill would set up a mechanism for EPA and the National Highway Traffic Safety Administration to work with California and the auto industry to set future fuel economy rules, would exempt states that already have cap-and-trade programs, would prevent EPA from regulating greenhouse gases under the several Clean Air Act provisions, would setup a sector-by-sector cap-and-trade program, and would require a 50% cut in emissions from new coal-fired power plants contingent on the deployment of capture and sequestration capacity. Overall, the draft would cut greenhouse gas emissions by 17% in 2020 and more than 80% by 2050. It would set a minimum and a maximum price for carbon emissions at $12 and $25, respectively. This bill has not yet been formally introduced. Doing so would have formally sent the bill to almost all of the committees in the Senate, each would have held hearings and markups, delaying floor consideration until the Fall. Instead, the draft bill was informally sent to each committee that would have jurisdiction and the committee was asked to make their suggested changes. These suggested changes would be made and then the bill would be formally introduced. The Leadership is hoping to save time by taking the bill directly to the floor, avoiding the formal committee markup process.

Even with this unorthodox strategy, it is not clear whether it has the votes to pass or not. President Obama has encouraged passage during a speech at a California solar energy facility and during a campaign stop to support Senator Barbara Boxer (D-CA). Early versions of the bill contained compromises that expanded off-shore drilling. Whether those will remain in the bill as a result of the current oil spill remains to be seen. Senate Majority Leader Harry Reed (D-NV) has indicated the bill will move forward in June. However, a number of Democrat Senators are now much more opposed to any bill that would expand off-shore drilling. While it is too early to declare either victory or defeat, the task of passing this legislation in this Congress certainly got harder based on the Gulf oil spill.

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.
