One Ashley Way Arcadia, Wisconsin 54612 Dear Mr. Wanek: Dee Freeman Secretary Subject: Permit No. WQ0000961 R.J. Reynolds Tobacco Company Davie County Storage Facility Wastewater Irrigation System Forsyth County In accordance with your permit modification request received June 20, 2012, we are forwarding herewith Permit No. WQ0000961, dated August 16, 2012, to Ashley Furniture Industries, Inc. for the continued operation of the subject wastewater treatment and surface irrigation facilities. - The subject permit has been modified to reflect a change of ownership from RJ Reynolds Tobacco Company to Ashley Furniture Industries, Inc. Please note that on August 5, 2009, Session Law 2009-406, entitled "An Act to Extend Certain Government Approvals Affecting the Development of Real Property Within the State," was enacted by the General Assembly and signed into law. The Act, known as the Permit Extension Act of 2009, extends the expiration date of certain government approvals and permits. On August 2, 2010, this Act was extended an additional year as Session Law 2010-177. The subject permit falls within the scope of this Act and is therefore being extended to August 31, 2017. This permit shall be effective from the date of issuance until August 31, 2017, shall void Permit No. WQ0000961 issued July 15, 2009, and shall be subject to the conditions and limitations as specified therein. Please pay particular attention to the monitoring requirements in this permit. Failure to establish an adequate system for collecting and maintaining the required operational information will result in future compliance problems.

The closure plan is required to include a schedule for attaining closure within 12 months of connecting to the county sewer system. A pump and haul permit must be obtained within three months of permit issuance from the Winston-Salem Regional Office to handle the wastewater in the event of a system failure before the sewer system is connected. Within eighteen (18) months of permit issuance, unless the facility is connected to the sewer system as proposed within the next 12 months, the facility will be required to demonstrate that the existing 3-acre irrigation field will adequately assimilate the wastewater associated with the 10,000 gpd design flow. Please note that the 24-acre irrigation field has been removed from the permit, and that semi- annual groundwater sampling is now required at monitor wells MW-1 and MW-4. Please also note the setback distances described under Permit Condition II.10. It is the Division's understanding that all of these setbacks have already been met, If there appears to be a conflict, please contact the Aquifer Protection Section. Please also note that since the last permit issuance, the Division has instituted a new monitoring policy for all non -discharge systems and created a new permit shell. Please pay careful attention to the monitoring frequencies and parameters listed in Attachment A, as they may differ from the requirements and frequencies in the last permit issuance If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an adjudicatory hearing upon written request within thirty (30) days following receipt of this permit.
