Hunt, Jr., Governor Jonathan B. Howes, Secretary A. Preston Howard, Jr., P.E., Director May 18, 1994 CERTIFIED MAIL - RETURN RECEIPT REQUESTED Jack King, City Manager City of Statesville Post Office Box 1111 Statesville, North Carolina 28687 Subject: Permit No. WQ0006245 City of Statesville Distribution of Class A Wastewater Residuals Iredell County Dear Mr. King: In accordance with your request for a permit amendment received on April 21, 1994, in the form of a "Petition for a Contested Case Hearing", we are forwarding herewith a draft Permit No. WQ0006245 to the City of Statesville. The objections expressed in your "petition" and the Divisions position on those concerns are discussed below: Objection 1: Condition 16 of Permit No. WQ0006245 places an extren7e prohibition on use of this product. Response 1: After doing further research concerning the use of a Class A product and additional information presented to the Division in negotiations with other municipalities, the Division agrees to delete this condition from the permit. Objection 2: Condition II 3 of Permit No. WQ0006245 eliminates alternative storage area without approval. The City of Statesville has stated in the permit application that the defunct drying beds are to be utilized to store the finish product. Response 2: When the permit was issued on March 21, 1994, the Division intended for the issuance of the permit to signify that the alternative storage, the drying beds, were approved. However, for clarity, the drying beds have now specified in the subject condition. Objection 3: Condition II 8 and II 9 should not be the permittee's responsibility except on the plant site. Response 3: Condition II 8 was intended to be the responsibility of the applier, which in this case, is not the responsibility of the City of Statesville. Therefore, the Division agrees to move this condition to the appropriate position, in Condition II 7. Condition lI 9 was intended to be the responsibility of the processor and only on the residuals treatment area, which in this case, is the responsibility of the City of Statesville. Therefore, the Division will not move or rewrite this condition. P.O. Box 29535, Raleigh, North Carolina 27626-0535 Telephone 919-733-7015 FAX 919-733-2496 An Equal Opportunity Affirmative Action Employer 50% recycled/ 10% post -consumer paper Page 2 Permit No. WQ0006245 DRAFT May 18, 1994 Objection 4: Condition 1110 and II 11 should be the customer's responsibility. Response 4: After doing further research concerning the use of a Class A product and additional information presented to the Division in negotiations with other municipalities, the Division agrees to delete Conditions H 10 and Conditions H 11 from the permit. Objection 5: Condition I1I 2 requires testing of all residuals. Products derived from multiple sources are considered one product and should be tested as such. Response 5: The testing that the Division is requiring is to be done on the finished product. If multiple residuals are to be blended prior to processing, then one test shall be completed on the finished product. This was the intention of the permit condition. The Division proposes to leave this condition unchanged. Objection 6: All language that refers to this product as residuals should be changed to reflect it as a single product. The term residuals should refer only to the constituent sludges used to form the product. Response 6: The Division considers even one product as "residuals" therefore the language in the permit shall remain the same. Please review this draft permit to see if the changes made with respect to your request are satisfactory. If the terms and conditions of this draft permit are acceptable to the City of Statesville, please inform this office by June 1, 1994 and the Division will proceed to issue the permit. Once the draft permit is accepted, the City of Statesville should immediately file the "Notice of Withdrawal of Petition", a copy of which is attached. If you need additional information concerning this matter, please contact Mr. Michael D. Allen at (919) 733-5083.

PERFORMANCE STANDARDS 1. The distribution of Class A residuals program shall be effectively maintained and operated as a non -discharge system to prevent the discharge of any wastes resulting from the operation of this program. DRA F�,f` 2. This permit shall become voidable in the event of failure of the residuals program to adequately protect the assigned water quality standards of the surface waters and groundwaters. 3. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface or groundwaters resulting from the operation of this program. 4. In the event that the residuals program is not operated satisfactorily, including the creation of nuisance conditions, the Permittee shall take any immediate corrective actions as may be required by the Division. 5. Diversion or bypassing of the untreated residuals or leachate from the residual treatment facilities is prohibited. 7. All leachate must be reused as a wetting agent for the processing of residuals or routed to the head of the treatment plant. 8. When wastewater residuals are sold or given away, one of the Class A pathogen requirements in 40 CFR Part 503.32(a) and one of vector attraction reduction requirements in 40 CFR Part 503.33 must be met. Additionally, an evaluation must be performed which demonstrates the residuals ability to comply with this requirement. Upon request, a copy of this evaluation must be submitted to the Assistant Chief, Technical Support Branch, Division of Environmental Management, Post Office Box 29535, Raleigh, NC 27626- 0535. In addition to the above, the Division has approved the following stabilization criteria for the City of Statesville: a. limekiln dust mixed sludge reaches a pH of 12 for 2 hours and the temperature in the heated sludge is maintained at a minimum of 700 C for a minimum of 30 minutes. b. N-Vino Soil Process Alternative 1 Fine alkaline materials are uniformly mixed by mechanical mixing into dewatered sludge to raise the pH to greater than 12 for seven days. The dewatered sludge cake is then air dried (while pH remains above 12 for at least seven days) through intermittent turning of windrows at least 30 days and until the solids levels reach and maintain a minimum of 65% solids. A solids concentration of at least 60% is achieved before the pH drops below 12. Mean temperature of the air surrounding the pile must be above 50 C (41 OF) for the first seven days. Alternative 2 Fine alkaline materials are uniformly mixed by mechanical mixing into dewatered sludge to raise the pH to greater than 12 for at least 72 hours. The sludge cake is then heated, while the pH exceeds 12, using exothermic reactions or other thermal processes to achieve temperatures of at least 520C (126F) throughout the sludge for at least 12 hours. The stabilized sludge is then air dried (while the pH remains above 12 for at least three days) to at least 50% solids. 9.
