April 19, 2001 Re: Glen Lyn Power Plant Title IV Acid Rain Permit Amendment AIRS ID No. 51-071-0002, Registration No. 20460 Dear Ms. Steele: On behalf of the Blue Ridge Environmental Defense League Board of Directors and over 2,200 members in Virginia, North Carolina, South Carolina, and Tennessee, I write to provide comments on the Glen Lyn Power Plant in Giles County, Virginia. These comments are supplemental to those provided in a letter to you dated February 8, 2001 by Mr. Mark Barker, our Board Vice President from Roanoke, Virginia. General Comments The draft permit dated January 5 incorporates a NOx averaging plan which would take the place of the standard emission limits in units 6, 51, and 52. We recommend denial of the draft permit based on the failure of the alternative contemporaneous emissions limitation plan to protect public health in Giles County, southwest Virginia, and in the nearby states of West Virginia, Kentucky, and North Carolina. The averaging of air pollution emissions among electric generating units of a particular utility group lacks the sound underpinning of science. It is a political engine which results in pollution hot spots, that is, higher levels of pollution in some communities in return for a promise of lower levels in another. But regional ozone chemistry does not obey human laws. And the proximity of other large pollution sources will confound the predictions of the best computer models. For example, Duke Powers Belews Creek coal-fired power plant north of Winston-Salem is closer to the Glen Lyn plant than AEPs Clinch River units in Russell County, Virginia. The huge levels of nitrogen oxides, sulfur dioxide, hydrochloric acid, sulfuric acid, and other pollutants from the Belews Creek plant, added to the pollution of Glen Lyn, will overwhelm the marginal predictions of Virginia DEQs computer model which already indicates that the proposed permit will raise local pollution levels to over 95% of national ambient air quality limits. AEPs 39 unit multi-state averaging plan is a shell game which, if approved by DEQ, would leave the people of Giles County the losers. Specific Comments The permitting authority must include explanations for proposed changes in emissions limits and monitoring for the facility. The DEQs draft permits Statement of Basis cites the statutory and regulatory authority for the issuance of the permit, but omits any explanation or justification for DEQs alteration of the existing permit. Nitrogen oxides emissions are principally responsible for ground level ozone pollution which causes shortness of breath, asthma, and shortens peoples lives. Several questions arise based on our reading of the draft permit:
The statement of basis must include DEQs rationale for new or less strict monitoring requirements and the statutory basis for the changes. A simple listing of rules and regulations is insufficient. Federal rules require that the permit application compliance plans include more than an identification of options under available to the permittee under the law. The permit must include additional information.
The proposed permit would allow huge increases in nitrogen oxide pollution. The draft permit contains maximum, rather than minimum, annual heat input limits for units 6, 51, and 52. According to 40 CFR 76.11, a maximum heat input value is required for utility units requesting less stringent emission limits. Therefore, it is fair to say that AEP expects these three units to generate higher annual NOx emissions.
In fact, the three units at Glen Lyn would emit 1,780 tons more NOx per year if the draft permit is granted by DEQ (Table 1). Added to the 7,022 annual tons of NOx emitted in 1999, AEPs emissions in Giles County would increase by 25%. The Glen Lyn plant would go from ninth to sixth place among the dirtiest stationary sources in Virginia. As Mr. Barker demonstrated in his comments of February 8, there has been a rising trend in annual NOx emissions at Glen Lyn since 1993. The citizens of southwest Virginia already bear a heavy burden from emphysema (7,093), chronic bronchitis (46,884), and asthma (adults 32,439, children 13, 847). The proposed increases in NOx and dangerous ground level ozone represent an added risk to public health which cannot be justified. Table 1.
