<br />e <br /> <br />e <br /> <br />PBS&J <br />ENVIRONMENTAL TOXJCOLOGY LABORATORY <br /> <br />Mr Stephen L GiIIett <br />City of La Porte <br />4 August 1999 - Page 2 <br /> <br />task 2 - TRE Action Plan and Schedule <br /> <br />PSS&J will prepare a comprehensive TRE Action Plan and schedule to be submitted to the TNRCC and <br />copies to the Region 6 EPA officers. The Action Plan will provide a description of the technical approach and <br />methodologies as required forthe examination and characterization ofa causative toxicant(s}. a sampling plan <br />for toxicity tests and chemical analyses. a quality assurance plan and project staff organizatic:1. <br /> <br />Task 2 COST: (16 hrs Sr. Scientist + 4 hrs Clerical); not more than: <br /> <br />S 2,000.00 <br /> <br />Task 3 - Monthlv Biomonitorina <br /> <br />PBS&J can provide quality biomonitoring during the TRE. Because the state pennit has an "escape clause" <br />requiring at least 12 monthly tests using the effected species, M. bahia (paragragh 5.e, pg 29), this task will <br />be costed at our nonnal biomonitoring rate. This cost includes sample pick-up, testing and report production. <br />Sampler rental services are available at $75 per use day (a chronic test uses 3 samples). <br /> <br />Task 3 COST: (12 X $850Itest) <br /> <br />$10,200.00 <br /> <br />Additional cost for SAMPLER rental (if requested) @ $75/day (3XS75= $225 per monthly test) <br /> <br />Task 4 - Phase 1 Characterization <br /> <br />A primary part of the TRE process is the perfonnance of a Phase 1 Toxicity Characterization. In association <br />with the three samples collected for chronic biomonitoring, if this test shows toxicity, PBS&J will conduct acute <br />toxicity screens of each of three effluent samples to see if toxicity is persistent The sample with greatest <br />potency will be tested using the Phase 1 characterization protocol (Figure 1). If Phase 1 results warrant, one <br />or more additional elution steps may be required for (hydrocarbon-based) toxicant verification. <br /> <br />Cost for Task 4 will be charged according to the attached Price Schedule; analytical chemistry associated with <br />Phase 1 will depend on analytes tested; analyses will be subcontracted at the City's preference. <br /> <br />Estimated Task 4 COST for Testing: <br />$450(3 screens) + $3.500 (Phase 1) + $750 (chemistry) = <br />additional elution steps as needed up to <br />Estimated Task 4 COST for Data Evaluation & Reporting up to <br />(16 hrs Sr. Scientist + 4 hrs Clerical) Subtotal <br /> <br />$ 4,700.00 <br />$ 1.825.00 <br />$ 2.000.00 <br />$ 8.525.00 <br /> <br />Task 5 - Confinnation of Toxicant Identification <br /> <br />If a toxic sample is collected and the Phase 1 (TASK 4) provides chemical identification, effluent sampleing <br />should be increased in order to capture another toxic sample for confinnation. This process may require: 1} <br />additional sampling, 2} an additional full or partial Phase 1 characterization series, and 3} chemical <br />identifications. The total cost for Task 5, based on the attached TIE price Schedule and assuming each of <br />the above tests are performed, is estimated to be : <br /> <br />Estimated Task 5 COST for Testing: <br />$3.750(Phase 1) + $1200( up to 8 sample screens) + $750(chemistry) = $5,700. <br />
