R H GRAHAM, NC 27253 PHONE (336) 570-6700 FAX (336) 570-6703 November 12, 2021 Mr. Aaron Holland Interim City Manager City of Graham 201 South Main Street Graham, NC 27253 Subject: MS4 Stormwater Program Audit Report Response to Audit Dear Mr. Holland, As you are aware, NC DEQ's Division of Energy, Mineral, and Land Resources (DEMLR) conducted an audit of the City's Municipal Separate Storm Sewer System (MS4) on October 6th and 7th, 2021. The audit was conducted by DEMLR staff from the Winston Salem Regional Office and included a zoom audit review of program implementation and one day of field visits in order to determine the City's compliance with its NPDES Phase 2 MS4 stormwater permit and comprehensive stormwater management plan (CSWMP). The audit was the second time that the City has been audited with the most recent audit being completed in March 2014. The previous audit did not involve identification of any deficiencies. The City was also praised by EPA and DEQ for it's stormwater program during creation and implementation of the Little Alamance Creek Category 4b program creation. The Little Alamance Creek program is built upon the basis of the City's MS4 stormwater program. The City received its audit report from DEMLR on October 15th, 2021. The audit report included a Notice of Deficiency (NOD) based upon minor deficiencies identified in the audit report. After a review of the audit report and NOD, we concur that there are improvements that can be made to the City of Graham's stormwater program. However, there are several identified deficiencies in the report that we believe are incorrectly noted, outside the purview of the audit/permit, or directly related to the City's previously approved annual reports. The following is a review of these concerns as well as changes that the City needs to address in the near future: Items of Concern from the Audit: The City submits an annual report summarizing the status of the stormwater program. This narrative style report is intended for use by NC DEMLR for evaluation of the City's program, but it also serves to inform elected officials, staff, and citizens of Graham. We use the same report format for several communities as it has been successful in outlining the programs while providing requested information to those stakeholders. The City's report is submitted every year in accordance with DEMLR requirements and receipt of this report is confirmed each year through email by DEMLR. The annual report will be revised as requested but it is difficult to understand how this is a noted deficiency when it City of Orabam City of Cnaham City Engineer: Josh Johnson, P.E.

Phone Number: (336)226-5534 City of Graham MS4 Stormwater Audit Response Page 2 November 12, 2021 was not noted in the previous audit nor in the approval of the annual report in 2019. It is also unclear as to how the auditors questioned if the audit report was submitted to DEQ. 2. The auditors commented on the City's sanitary sewer overflows in the audit report and during the audit. While we included collection system improvements within the Little Alamance Creek program, the City's collection system is not subject to the City's MS4 program and is regulated through a separate collection system permit. This appears to be outside of the MS4 Auditors purview. 3. The audit report's section on Illicit Discharge Detection and Elimination (IDDE) includes several areas that appear incorrect based upon the audit and the documents provided for the audit. In particular: a. The audit notes that the outfall map does not who major outfalls or not but it was reviewed during audit electronically and noted that each outfall is classified in GIS based upon size and land usage. As you are aware, the City has worked fairly hard to improve its GIS updating process and it's unclear how the auditors got this impression. b. The audit report notes that "dedicated procedures for investigating illicit discharges, specific to the permittee, were not located." The auditors may have missed this, but the IDDE program includes very specific IDDE procedures and these were provided to the auditors. This item was directly addressed verbally in the process for how IDDE reports are handled during the audit. 4. The audit reports section on Post Construction Site Runoff Controls notes that the City implements a Neuse River Basin NSW. However, the City of Graham is not in the Neuse River Basin but rather the Cape Fear River Basin. The City's NSW program is directly affected by the legislative actions regarding the Jordan Lake Rules. The City's Jordan Lake Stage 1 and Riparian Buffer programs were briefly touched on during the audit as well as in the annual report and the new development stormwater overviews. 5. The audit report suggests improvements to the City's documentation of logging of reviews and inspections for new development projects, but no suggestions are made on how to do this. The City's process of including stormwater within the TRC process was well documented during the review process as well as the plans that triggered the stormwater ordinance. It is unclear how the auditors think this could be improved. 6. At the Graham Wastewater Treatment Plant, the auditors appear to have misunderstood that the site has never had a NC DEQ stormwater compliance inspection. The site has been visited regularly for City of Graham stormwater compliance visits. Response Actions: 1. Respond to DEMLR noting these concerns and that the City plans to comply with the audit findings (outside of some of those items noted above). 2. Conduct a self -audit of the City's Public Education and Outreach and Public Involvement programs. 3. Develop a draft Stormwater Management Plan (updated CSWMP). 4. Submit a new permit application after approval of the draft SWMP (above). 5. Improvements to the Annual Report addressing issues noted. City of grabam City of Graham City Engineer: Josh Johnson, P.E.

Update the City's facility O&M plans. This includes revising the Stormwater Prevention Plans for Public Works and for the Wastewater Treatment Plant. 8. Create specific tracking mechanism for O&M site inspections. In reviewing the audit report and the audit process, the auditors had several worthy suggestions to make the City's stormwater program better. A better program will benefit the citizens of the City by improving water quality but I believe after reviewing the audit report that the report is overly hard in its assessment of the program and that there were several items that were overstated or misstated. As always, it is our pleasure to work with the City of Graham and if you would like to discuss any of the above items, please let me know. Sincerely, Josh Johnson, P.E.
