§7651n Clean Coal Technology Regulatory Incentives

Title 42 › CHAPTER 85 — AIR POLLUTION PREVENTION AND CONTROL › SUBCHAPTER IV–A — ACID DEPOSITION CONTROL › § 7651n

Summary

Allows certain clean coal demonstration projects and some restarted coal units to avoid some Clean Air Act performance and permit rules, as long as pollution does not increase and other conditions are met. Temporary demonstration projects run five years or less and that follow the State plans and national air-quality standards are not subject to the Act’s new-source performance standards or certain permitting programs. Permanent demonstration projects that repower a unit are also exempt from those performance standards and permitting reviews for any pollutant whose potential emissions do not go up. The Environmental Protection Agency must write rules within 12 months after November 15, 1990, to make these changes work, and States can choose to adopt matching changes where they run the permitting program. Definitions and a restart exemption in one line each: clean coal technology — new or existing methods at any combustion stage that cut sulfur dioxide or nitrogen oxide emissions from coal and were not widely used on November 15, 1990. clean coal technology demonstration project — a project using up to $2,500,000,000 in DOE “Clean Coal Technology” funds (or similar EPA funds) with at least 20% federal funding. Restart exemption — a coal unit that was off for the two years before November 15, 1990, kept in the emissions inventory, had prior controls removing at least 85% of SO2 and 98% of particulates, is fitted with low-NOx burners at restart, and otherwise meets the law, may restart without triggering the listed performance or permitting rules.

(a)“Clean coal technology” defined
For purposes of this section, “clean coal technology” means any technology, including technologies applied at the precombustion, combustion, or post combustion stage, at a new or existing facility which will achieve significant reductions in air emissions of sulfur dioxide or oxides of nitrogen associated with the utilization of coal in the generation of electricity, process steam, or industrial products, which is not in widespread use as of November 15, 1990.
(b)Revised regulations for clean coal technology demonstrations
(1)Applicability
This subsection applies to physical or operational changes to existing facilities for the sole purpose of installation, operation, cessation, or removal of a temporary or permanent clean coal technology demonstration project. For the purposes of this section, a clean coal technology demonstration project shall mean a project using funds appropriated under the heading “Department of Energy—Clean Coal Technology”, up to a total amount of $2,500,000,000 for commercial demonstration of clean coal technology, or similar projects funded through appropriations for the Environmental Protection Agency. The Federal contribution for a qualifying project shall be at least 20 percent of the total cost of the demonstration project.
(2)Temporary projects
Installation, operation, cessation, or removal of a temporary clean coal technology demonstration project that is operated for a period of five years or less, and which complies with the State implementation plans for the State in which the project is located and other requirements necessary to attain and maintain the national ambient air quality standards during and after the project is terminated, shall not subject such facility to the requirements of section 7411 of this title or part C or D of subchapter I.
(3)Permanent projects
For permanent clean coal technology demonstration projects that constitute repowering as defined in section 7651a(l) of this title, any qualifying project shall not be subject to standards of performance under section 7411 of this title or to the review and permitting requirements of part C for any pollutant the potential emissions of which will not increase as a result of the demonstration project.
(4)EPA regulations
Not later than 12 months after November 15, 1990, the Administrator shall promulgate regulations or interpretive rulings to revise requirements under section 7411 of this title and parts C and D,2 as appropriate, to facilitate projects consistent in this subsection. With respect to parts C and D,2 such regulations or rulings shall apply to all areas in which EPA is the permitting authority. In those instances in which the State is the permitting authority under part C or D,2 any State may adopt and submit to the Administrator for approval revisions to its implementation plan to apply the regulations or rulings promulgated under this subsection.
(c)Exemption for reactivation of very clean units
Physical changes or changes in the method of operation associated with the commencement of commercial operations by a coal-fired utility unit after a period of discontinued operation shall not subject the unit to the requirements of section 7411 of this title or part C of the Act 2 where the unit (1) has not been in operation for the two-year period prior to the enactment of the Clean Air Act Amendments of 1990 [November 15, 1990], and the emissions from such unit continue to be carried in the permitting authority’s emissions inventory at the time of enactment, (2) was equipped prior to shut-down with a continuous system of emissions control that achieves a removal efficiency for sulfur dioxide of no less than 85 percent and a removal efficiency for particulates of no less than 98 percent, (3) is equipped with low-NOx burners prior to the time of commencement, and (4) is otherwise in compliance with the requirements of this chapter.
