TONY LEOPARD, REGIONAL PLANT MANAGER TRIGEN-BIOPOWER, INC. 302 DUKE STREET FOREST CITY, NORTH CAROLINA 28043 Subject: Permit No. WQ0010689 Trigen-BioPower, Inc. North Cove Steam Generation Plant Ash Distribution Program Distribution of Residual Solids (503 Exempt) McDowell County Dear Mr. Leopard: In accordance with your permit renewal and modification application package received on March 26, 2004 as well as the additional information subsequently received, we are forwarding herewith a renewed and modified Permit No. WQ0010689, dated December 30, 2005, to Trigen-BioPower, Inc. for the subject ash distribution program. This permit shall be effective from the date of issuance until November 30, 2010; shall void Permit No. WQ0010689, issued on July 7, 2000; and shall be subject to the conditions and limitations as specified therein- Make note of this permit's expiration date and the fact that a permit renewal application is due to the Division of Water Quality (Division) no later than six months prior to that date (i.e., see Condition VI.7.), as the Division does not send reminders to apply for permit renewal. This permit has been issued to approve the operation of an ash distribution program out of Trigen-BioPower, Inc.'s North Cove Steam Generation Plant in Marion, North Carolina for another five- year cycle. This permit has also been modified to allow up to 3,200 dry tons per year of ash (i.e., increased from 2,500 dry tons per year of ash) to be distributed through the program. As always, remember to take the time to review this permit thoroughly, as some of the conditions contained therein have been added, changed, or deleted since the last issuance. Pay particular attention to the monitoring requirements in this permit. Please be aware that failure to establish an adequate system for collecting, maintaining, and submitting the required operational information will result in future compliance problems. Of particular interest to you are the following (i.e., not an inclusive list) - Condition 1. 2.: This condition requires that the Permittee conduct an assessment/feasibility study of alternatives to the on-site ash storage/stockpile site within 90 calendar days of permit issuance. Following the assessment/study, the Permittee must provide written notification to the Division that details which of three stipulated options is selected for implementation. Each option has additional compliance schedule requirements.

In the permit renewal/modification application package, it is stated that leachate from the site is managed through the stormwater general permit for the steam generation plant as a whole (i.e., NCG210028). You may want to discuss the compliance status of the ash storage/stockpile site with the Division's Stormwater Pennitting Unit. ♦ Condition II. 3.: This condition specifies the maximum volume of ash that may be distributed, the types of ash that may be distributed, as well as the uses for which the ash may be distributed. It is clarified here that ash that does not fall under the "wastewater residuals" definition such that is administered under the purview of the Division is approved to be distributed under the conditions of this permit. The Division has verified this approach as being acceptable with the Composting and Land Application Branch of the Division of Waste Management. ♦ Condition 111. 2.: This condition requires that information about how the various ash products (i.e., bottom ash, fly ash, scrubber ash, or mixture thereof) is distributed throughout a calendar year be provided with the annual report. A justification for how the ash sampling program was conducted is required as well. ♦ Condition III. 3.: The permit has been modified to require hazardous waste characterization testing (i.e., corrosivity, ignitability, reactivity, and toxicity characteristics leaching procedure) on specific schedules. Past analytical results have indicated that the ash can, on occasion, fail corrosivity (i.e., demonstrate a pH greater than 12.5). The Permittee should contact the Hazardous Waste Section of the Division of Waste Management for guidance as to what action should be taken in the event that a failed corrosivity test occurs again. Note that it may not be appropriate to distribute the ash under the conditions of this permit in such situations. ♦ Condition III. 4.: The permit has been modified to require metal, nutrient, and micronutrient testing of the ash on a frequency that is dependent on the volume of ash distributed. Note that, as requested in the cover letter of the permit renewal/modification application package, the analytical requirement is for the total concentrations of the parameters and not of those detected in a leachate. ♦ Condition III. 5.: This condition requires that all analytical work be completed on the ash as it is to be distributed, which means that the Permittee will have to take special care to sample appropriately and representative depending on how the various ash products generated by the steam generation plant are mixed and distributed. This condition also requires that all laboratory analyses be performed by a laboratory that is Division -certified for the parameter being analyzed. Past annual reports have indicated that the Permittee has utilized the NC Department of Agriculture and Consumer Services laboratory to analyze the ash for specific parameters. The Permittee should contact the Laboratory Certification Unit of the Division's Laboratory Section for verification that this laboratory is appropriately certified. ♦ Condition III. 5.: This condition spells out the information that must be included in the annual report that describes the activities undertaken under the conditions of this permit during each calendar year. During the last permit cycle, the Permittee has submitted the annual report such that it is received a couple of days past the March 1St deadline. The Permittee should make a special effort to prepare and submit the annual report in a timely fashion in order to avoid potential compliance problems. Also, the Permittee should check the Division's web site prior to preparing the annual report in order to download the most - recent version of the reporting forms to use. Mr. Tony Leopard December 30, 2005 Page 3 If any parts, requirements, and/or limitations contained in this permit are unacceptable, you have the right to request an adjudicatory hearing upon written request within 30 calendar days following receipt of this permit.
