Identification tape shall be at least three inches wide and have white or black lettering on purple (i.e., Pantone 522) field stating "CAUTION: RECLAIMED WATER — DO NOT DRINK." Identification tape shall be installed on top of reclaimed water pipelines, fastened at least every 10 feet to each pipe length and run continuously the entire length of the pipe. iii. Existing underground distribution systems retrofitted for the purpose of distributing reclaimed water shall be taped or otherwise identified as noted above. This identification need not extend the entire length of the distribution system, but shall be incorporated within 10 feet of crossing any potable water supply line or sanitary sewer line. c. All reclaimed water valves and outlets shall be of a type, or secured in a manner, that permits operation by authorized personnel only. WQ0023693 Version 2.1 Shell Version 090806 Page 6 of 15 d. Above -ground hose bibs (i.e., spigens or other hand -operated connections) shall not be present. Hose bibs shall be located in locked below -grade vaults that shall be clearly labeled non -potable. As an alternative to the use of locked below -grade vaults with standard hose bibs services, hose bibs, which can only be operated by a special tool or connected to a special hose connection, may be placed in non -lockable underground services boxes clearly labeled non -potable. 8. The Permittee shall maintain an active cross -connection control program that shall have the following minimum requirements: a. No direct cross -connections shall be allowed between the reclaimed water and potable water systems. b. Where both reclaimed water and potable water are supplied to a reclaimed water utilization site, a reduced pressure principle backflow preventer, an approved air gap separation or other Division of Environmental Health approved device shall be installed at the potable water service connection to the use area. The installation of the reduced pressure principle backflow prevention device shall allow proper testing. c. Where potable water is used to supplement a reclaimed water utilization system, the Permittee or potable water supplier shall approve and regularly inspect the air gap separation. 9. Reclaimed water distribution lines shall be located 10 feet horizontally from and 18 inches below any water line where practicable. Where these separation distances cannot be met, the piping and integrity testing procedures shall meet water main standards in accordance with 15A NCAC 18C. 10.

The compliance boundaries for the high rate infiltration basins at the IP Tract and the Mercer Mill Sites, shall be specified in accordance with 15A NCAC 02L .O1O7(b). This disposal system was individually permitted on or after December 30, 1983; therefore, the compliance boundary is established at either 250 feet from the effluent disposal area, or 50 feet within the property boundary, whichever is closest to the effluent disposal area. An exceedance of groundwater standards at or beyond the compliance boundary is subject to remediation action according to 15A NCAC 02L .O1O6(d)(2) as well as enforcement actions in accordance with North Carolina General Statute 143- 215.6A through 143-215.6C. 15. In accordance with 15A NCAC O2L .0108, the review boundaries for the high rate infiltration basins at the IP Tract and the Mercer Mill Site are established midway between the compliance boundary and the effluent disposal area. Any exceedance of groundwater standards at the review boundary shall require action in accordance with 15A NCAC 02L .0106. WQ0023693 Version 2.1 Shell Version 090806 Page 7 of 15 16.

The measurement of water levels shall be made prior to purging the wells. The depth to water in each well shall be measured from the surveyed point on the top of the casing. The measurement orpl I shall be made after purging and prior to sampling for the remaining parameters. 3. The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the relative elevation of the measuring point for each monitoring well. The measuring points (top of casing) of all monitoring wells shall be surveyed relative to a common datum. 4. Volatile Organic Compounds (VOC) - In November only, analyze by one of the following methods: a. Standard Method 62301). PQL at 0.5 µg/1, or less h. Standard Method 6210D. PQL at 0.5 µg/L or less C. EPA Method 8021. Low Concentration, PQI, at 0.5 fig/L or less d. IPA Method 8260, Low Concentration, PQI, at 0.5 µg/L or less c. Another method with prior approval by the Aquilcr Protection Section Chief Any method used must meet the following qualifications: a. A laboratory must be DWQ certified to rum any method used. b. The method used must, at a minimum, include all the constituents listed in Table Vlli of Standard Method 6230D. e. The method used must provide a PQL of 0.5 jig/I, or less that must be supported by laboratory proficiency studies as required by the DWQ Laboratory Certification Unit. Any constituents detected above the MDL but below the PQL of 0.5 µg/L must be qualified (estimated) and reported. 5. If any volatile organic compounds (VOC) are detected as a result of monitoring as provided in Attachment C, then the Wilmington Regional Office Aquifer Protection Supervisor, telephone number (910) 796-7215, must be contacted immediately for further instructions regarding any additional follow-up analyses required. 6. If 'I'OC concentrations greater than 10 mg/I are detected in any downgradient monitoring well, additional sampling and analysis must be conducted to identify the individual constituents comprising this TOC concentration. If the TOC concentration as measured in the background monitor well exceeds 10 mg/l, this concentration will be taken to represent the naturally occurring TOC concentration. Any exceedances of this naturally occurring TOC concentration in the downgradient wells shall be subject to the additional sampling and analysis as described above. 7. Monitoring wells shall be reported consistent with the nomenclature and location information provided in Figure I and this attachment.
