Mr. Shawn Napier, P.E. <br />July 1 S, 2007 <br />Page 2 <br />sampling activities, assessment piezometers P-13, P-14 and replacement piezometer P- <br />l0A were installed. Groundwater sampling and analyses were completed in June and <br />December 1998. These analytical results (from about 8,5 years ago} 'indicated VOCs in <br />groundwater at concentxations exceeding EPA. drinking water standards were present at <br />the northern landfill boundary (in piezometers P-11; P-13 and P-14}, and had migrated off <br />site beyond the southeast landfill boundary (in the vicinity of piezometers P-2 and' P-~}. <br />Based on conversations with City personnel, no leachate has been pumped from the <br />landfill since at least 1998. According to Mr. Arten Avachian of the TCEQ, no required <br />project summary report summarizing these activitaes has been submitted to the TCEQ. <br />Our review of TCEQ correspondence, the City's project files, and WBC's case files <br />indicate WBC does not have a complete set of landfill case records. <br />Rroposed Services <br />This proposal's services axe based on available project information, and are designed to <br />address the previously noted TCEQ.. iiivestigatioh zequireixients fai ~~.tlie `site and to <br />.......determine if a persistent groundwater VOC~ contamination issues are` present, Xf <br />groundwater contamination above-the EPA, drinking water standards is riot reported in the <br />proposed sampling events, the project status report will present a plan to allow the site to <br />exit the postclosure period, In the event persistent groundwater contamination is <br />confirmed by the proposed groundwater analyses, the project status report will contain a <br />Remediation Plan. <br />Task 1- TGEQ Response Letter <br />WBC will prepare an initial TCEQ response letter that briefly summarizes the project <br />activities completed since 199$ and the City's future project plans described in this <br />proposal's Tasks 3, 4, and 5. The purpose of this letter is to avoid a possible TCEQ NOV <br />notice of violation) letter while the landfill is collecting additional groundwater data and <br />preparing a course of action. Two draft copies of the initial response lettez will be <br />prepared and submitted to the City for review. After incozporation of mutually-agreed <br />City suggestions and changes, five final copies of the TCEQ response letter will be <br />submitted to the City and TCEQ. <br />Task ~ - TGEQ Record Search <br />As noted in the project understanding, the available infarmation indicates WBC lacks <br />previous investigation report information. To better plan project strategy and avoid <br />duplicating previous investigation activities, WBC will procure the services of a TCEQ <br />file search firm to obtain all available case records in the TCEQ's Austin azchives. WBC <br />will make a duplicate set of the TCEQ information obtained for the City's records. <br />Q;ICITYOFPAR7SfPROPOSALICWARDAOS~lL07.07.DOC ~~~~~ ~~ ~~~a~ <br />
