Pressley, PE Sr. Environmental Engineer Please find enclosed one original signed stormwater discharge monitoring report (DMR) containing a turbidity and total suspended solids exceedances. The stormwater sample was taken on December 14, 2018. Martin Marietta received the sample results, containing the turbidity exceedance, via email December 25, 2018. Environmental staff did not return to work until January 2, 2018, so the notification was in effect delayed until this time. The results triggered a Tier I responses for turbidity and total suspended, as these are the first valid sample results of the period and the previous period's sample results were below the benchmarks. On January 4, 2019, regional environmental staff performed a site review with site staff to identify and evaluate possible causes of the exceedance. Implementation of actions identified during the evaluation is underway. If you have any questions or need additional information please contact me at (919) 783-4505 or via email at phillip.pressley@martinmarietta.com. Sincerely, Phillip N.

The lab reported the results to us on 5/10/13. The sample was collected at the outfall and not in the receiving stream. There is no easy and safe access to collect up -stream samples. In addition, the day the sample was collected it rained 1.0" in 35 minutes. We believe this intense heavy thunderstorm caused not only an upset condition with respect to our stormwater sample but would have caused significantly high turbidity levels in the receiving stream. On 5/13/13 1 conducted a stormwater management inspection as called for by the NPDES General Permit Conditions. Having inspected the stormwater outfall, it did appear that the sediment trap had adequate capacity and that the weir was in satisfactory condition. However, in an effort to be proactive we have decided to build an extra sediment trap in front of the existing one to allow for increased settling time. We think the effect of placing the sediment traps in sequence will minimize the potential for a future exceedance. On 5/3 U13 the new sediment trap was constructed, I have attached photos of the newly built sediment trap. Also, please find attached a copy of the stormwater management inspection as well as a stormwatcr exceedance DMR. Sincerely, Nuwan Wijesuriya Environmental Engineer Attachment CC: Roger Ramey, Steve Reel Stormwater Management Inspection Site: American Stone Quarry Date stormwater sample was collected: 5/6/13 @1:10 PM Outfall location: Land Disturbance Stormwater Discharge (SDO2) Benchmark Parameter Exceeded: Turbidity (Result 116 NTU) Date of Lab Results: 5/10/13 Date of Stormwater Management Inspection: 5/13/13 Personnel in attendance: Nuwan Wijesuriya Inspection Observations: I visited the site and looked at the Land Disturbance stormwater outfall at which the sample had been collected. The sediment trap was not full and the weir appeared to be okay. The day on which the stormwater sample was collected 1" of rainfall fell in a period of 35 minutes. This short and intense heavy thunderstorm probably caused the upset condition. By the end of the day the rainfall total was 1.5". However, in an effort to be proactive we decided to build an extra sediment trap in front of the existing one to allow for increased settling time. We believe the effect of placing the sediment traps in sequence will minimize the potential for a future exceedance. Arrangements will be made to have the new sediment trap built. Date of Selected Actions Implemented: 5/31/13 The new sediment trap has been constructed as evidenced by the photos.

Our land disturbance stormwater sample analysis for turbidity was 52.4 NTU. The result was just slightly above the 50 NTU benchmark. However, the sample was collected at the outfall and not in the receiving stream and therefore we think that the existing natural turbidity level of the receiving stream was not increased. On 9/25/12 1 conducted a stormwater management inspection as called for by the NPDES general permit conditions. Having inspected the stormwater outfall, although there did not appear to be any obvious problems I determined that the best solution would be to clean out the sediment trap and place new filter stone. These repairs were made on 10/16/12. Please find attached a copy of the stormwater management inspection as well as a stormwater exceedance DMR.

As you may recall, quarry personnel had collected stormwater samples in December 2011 without realizing that stormwater samples only need to be collected if a discharge truly occurs offsite. Unfortunately the employee collecting the stormwater samples did not realize this and had collected them when there was no discharge from the outfalls. The employee was under the impression that he had to collect a sample regardless, and had therefore collected them from within the sediment traps which is why the benchmark parameters were exceeded. This information was gathered by me on January 10, 2012 when I conducted a stormwater site inspection as called for under the Tier 1 response requirements. Since the time of the inspection the plant personnel has been trained on the proper sampling procedure, and based on your suggestion we will develop a standard operating procedure (SOP) for the collection of stormwater samples. A copy of the SOP will be attached to our Stormwater Pollution Prevention Plan (SPPP) that is currently on file at the quarry office. Thank you for your assistance on the matter.
