Analytical sampling shall be performed during a measurable storm event. Samples shall be taken on a day and time that is characteristic of the discharge. All samples shall be taken before the discharge joins or is diluted by any other waste stream, body of water, or substance. Monitoring points as specified in this General Permit shall not be changed without notification to and approval of the Permit Issuing Authority [40 CFR 122.41(j)]. Recording Results For each measurement or sample taken pursuant to the requirements of this General Permit, the permittee shall record the following information [40 CFR 122.41]: • The date, exact place, and time of sampling or measurements, • The individual(s) who performed the sampling or measurements; • The date(s) analyses were performed; • The individual(s) who performed the analyses; • The analytical techniques or methods used; and • The results of such analyses. Flow Measurements Where required, appropriate flow measurement devices and methods consistent with accepted scientific practices shall be selected and used to ensure the accuracy and reliability of measurements of the volume of monitored discharges. Test Procedures Test procedures for the analysis of pollutants shall conform to the EMC regulations published pursuant to NCGS 143-215.63 et. seq, the Water and Air Quality Reporting Acts, and to regulations published pursuant to Section 304(g), 33 USC 1314, of the Federal Water Pollution Control Act, as Amended, and Regulation 40 CFR 136. To meet the intent of the monitoring required by this General Permit, all test procedures must produce minimum detection and reporting levels and all data generated must be reported down to the minimum detection or lower reporting level of the procedure. If no approved methods are determined capable of achieving minimum detection and reporting levels below the General Permit discharge requirements, then the most sensitive (method with the lowest possible detection and reporting level) approved method must be used. Representative Outfall If a facility has multiple discharge locations with substantially identical stormwater discharges that are required to be sampled, the permittee may petition the Director for representative outfall status. If it is established that the stormwater discharges are substantially identical and the permittee is granted representative outfall status, then analytical sampling requirements may be performed at a reduced number of outfalls.

DEWATERING METHOD Specific mining areas within the mining permit boundary will not be determined until the excavation has begun. The mining will occur wherever the marl & gravel are concentrated on the site. Various potential pumping locations have been shown throughout the site. The water will be piped to the existing ponds on -site where the suspended sediment will settle out and the water will outfall to the existing perimeter ditches. EROSION AND FLOOD PREVENTION Silt fence will be installed along the haul road or where wetlands are immediately adjacent. Other measures will be implemented as deemed necessary.
