North Carolina 27612 <br />TeL 919 787-5620 Fax: 919 781-5730 <br /> <br />September 6, 1995 <br /> <br />Dr. William F. Pilkington <br />Health Director <br />Cabarms County Health Department <br />715 Cabarms Avenue West <br />Concord, North Carolina 28025 <br /> <br />Re: <br /> <br />Transmittal of Amendment No. 11 <br />Additional Assessment Monitoring <br /> <br />Dear Fred: <br /> <br />Please find enclosed three (3) executed copies of Amendment No. 11. This Amendment is <br />intended to cover our services associated with the additional assessment monitoring sampling <br />required at Units 2 and 3. Please provide an authorizing signature on each copy of the <br />Amendment and return two copies to me. <br /> <br />Additional assessment monitoring is necessary since bis (2-ethylhexal) phthalate was detected <br />at the landfill during the initial assessment monitoring sampling. The letter from Mr. Bobby <br />Lutfy, dated August 23, 1995, requires that the County establish a baseline concentration for <br />this constituent. In conjunction with collection of the baseline sampling, this amendment <br />also includes the samples necessary to fulfill the requirements in the regulations, such as the <br />full Appendix I scan and the full Appendix 11 scan required once a year. The schedule <br />provided in the amendment follows the outline provided by Mr. Bobby Lutfy during the last <br />SWANA meeting. This document is attached for your information. In addition, during the <br />second sampling event, CDM will also collect and analyze the two surface water samples as <br />part of the routine semi-annual detection monitoring required. <br /> <br />Also it should be noted that in order to analyze a sample for the one constituent, bis (2- <br />ethylhexal) phthalate, it is necessary for the laboratory to do the full semi-volatile organic <br />compound scan ( using Method 8270). The analytical equipment is preset to analyze for all <br />the SVOCs and it is cost prohibitive for the laboratory to reset the equipment for one <br />compound. In other words, the cost to analyze for all the SVOCs would be the same or less <br />than the cost to analyze for just one compound. <br /> <br /> <br />
