The following guidelines are presented to assist you in complying with those requirements. If you have any questions concerning these matters, you should contact Don Link at the address shown below to discuss the requirements relevant to your specific facility: Asheville Regional Office 59 Woodfin Place Asheville, NC 28801 (704) 251 -6208 1 . Condition No. 16: The installation of monitor wells as approved by the Department ' s Regional Asheville Office. THE MONITOR WELLS MUST BE DEVELOPED , TO A TOTAL SUSPENDED SOLIDS LEVEL NOT EXCEEDING 5 mg/L. Prior to accepting a new well, you should verify that the driller has developed the well to an acceptable level as stated above. Failure to do so may result in samples containing excessive amounts of suspended solids, due to improper well PQ.fox 29545.

The North Carolina Well Construction Standards 15A NCAC 2C . 0105 require that a Permit be issued prior to construction of any monitoring well, and therefore permit application forms are - attached for your convenience. To facilitate the permitting process, you should contact the appropriate Regional Office personnel as described above, to discuss the location and construction requirements relevant to your specific facility. NOTE: Please disregard the above if installation of approved monitoring wells has already been completed. 2 . Condition No. 17 : Sampling of the referenced wells on the schedule and for the constituents listed • below: SCHEDULE: The monitor wells must be sampled initially after construction and thereafter every April, August and December. CONSTITUENTS: COD TDS (500. 0 ) Chloride (250 . 0) Orthophosphate SO4 Fecal Coliforms TOC Water Level Total Suspended Solids pH (6 . 5-8 . 5 standard units) Selenium (0 . 01 ) Magnesium Calcium Volatile Organic Compounds (in December Only by Method 1 or 2. below) Method 1 : Method 6230D (Capillary - Column) , "Standard Methods For The Examination of Water and Wastewater", 17th ed. , 1989 Method 2: Method 502 . 2 "Methods For The Determination Of Organic Compounds In Drinking Water", U.S. EPA - 600/4-88/039 If any volatile organic compounds are detected by method 6230D, or the equivalent method 502 . 2, then EPA methods 604 and 611 must also be run to detect other organic compounds which may be present. The results of all analyses specified in the monitoring requirements, including 604 and 611 if required, must be submitted simultaneously. The measurement of water levels must be made prior to sampling for the remaining parameters. The numbers in parentheses represent the maximum allowable concentrations in groundwater for the various analytical parameters, as specified in 15A NCAC 2L [Groundwater Classifications and Standards] . Unless otherwise specified, the units for these concentrations are expressed as milligrams per liter. If any volatile organic compounds are detected by method 6230D, or the equivalent method 502 . 2, then EPA methods 604 and 611 must also be run to detect other organic compounds which may be present. The results of all analyses specified in the monitoring requirements, including 604 and 611 if required, must be submitted simultaneously. If TOC concentrations greater than 10 mg/1 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/1, 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. A supply of forms (GW-59) on which the analytical results must be reported are attached. Instructions are provided on the reverse of the white copy of each 4-part form. The analytical results should be sent to the address shown at the top of the form and are due in our office no later than the last working day of the month following sample collection. Additional forms will be provided upon receipt of the attached form GW-59 RO.
