Description

Amend 0002 to EPA RIII RFQ DAS R3860. This notice is the Amend!!!! The hour and date specified for the receipt of quotations is amended to 9AM ET on Wed Sep 6, 2000. Quoters must acknowledge receipt of this amend prior to 9AM ET on Wed Sep 6 2000 by one of the following methods: a) by acknowledging receipt of this amend on quote submitted via fax to Environmental Protection Agency Region III, Contracts Branch (3PM10), attn: Sidney Ozer, Contracting Officer Fax 215/814-5211 M/F EPA RIII RFQ DAS R3860 due 9am ET We Aug 30 2000; or b) by separate fax which includes a reference to the RFQ and amend number. Failure of your acknowledgement to be received at the place designated for the receipt of offers prior to 9AM ET on Wed Sep 6 may result in rejection of your quotation. If by virtue of this amend you desire to change a quotation already submitted, such change may be made by fax, provided each fax makes reference to this RFQ and amend, and is received prior to 3PM ET on Wed Sep 6. All responsible sources may submit a quote via fax which shall be considered by the Agency. Item 0001, Aq EPA1613B Full Dioxin Congeners 176 ea @ $_____. Item 0002, Sediment EPA1613B Full Dioxin Congeners 16 ea @ $_____. Item 0003, Aq EPA160.3 Total Solids 88 ea @ $_____. Turn around time 30 days from receipt of samples. FOB destination Ft Meade, MD. Samples will be received by the lab from the date of order to Nov. 14, 2000. Lab must be able to receive samples on Saturdays. The cost of all QC samples, dilutions and reanalysis required must be incorporated into the unit prices. Sample delivery group is 20 samples or less per batch delivered to the lab within a span of 7 consecutive days. In the case of removal or response action involving the transfer of any hazardous substances, pollutants,or contaminants shall only be transferred to a facility which is operating IAW the requirements of Solid Waste Disposal Act (42 USCA 6924 & 6925). Award will be made on the basis of price alone. The Govt intends to make one award. Except as provided herein, all terms and conditions of the RFQ, as heretofore changed, remain unchanged and in full force and effect. The following are answers to questions received: 1) Could you please advise if you have detection limit requirements? Yes, there are detection limit requirements. 2)Do you require minimum levels reported or would you like the detection limits to be sample specific? Detection limits shall be as specified in Method 1613B, at a minimum. Concentrations of PCDD/PCDF isomers shall be reported at or above the "minimum level" for each sample. Isomers identified below the "minimum level" shall be reported by the laboratory and appropriately qualified as such for each sample. Detection limits are to be reported for isomers not identified in each sample. 3)Do you have information regarding historical or expected dioxin/furan levels at the site? Sediment sampling from various sampling points in the Kanawha River conducted in November 1998 identified dioxin (TEQ) up to 1.6 ppb with high proportion of the dioxin TEQ attributed to 2,3,7,8-TCDD). Sample results for sediment samples collected in May 2000 are not yet available, but may be higher than previously found in 1998. Ambient sampling of surface water from the Kanawha River using a hi-volume sample collection technique identified up to 0.4 pg/L. The samples (sediment and surface water) collected as part of this sampling event will be collected from various outfalls to the Kanawha River and include permitted NPDES discharges and stormwater outfalls, which were also part of an antiquated sewer system which served an industrial complex. To the Govt's knowledge, no specific dioxin data from NPDES or stormwater sewer outfalls is available. 4)What is the source of contamination? The principal source of dioxin contamination is believed to be the result of former industrial activity involved in the production of 2,4,5-T used in the production of herbicides. Other anthropogenic sources of dioxins may also have contributed to the total dioxin burden observed in the area such as incinerators, other industrial processes, electric power generation, automotive emissions, etc. 5)What data validation guidelines will be used? EPA Region III dioxin data validation guidelines will be used. 6) Do you have specified data quality objectives? The data quality objectives for precision and accuracy is that as specified in Method 1613B and EPA Region 3 data validation guidelines. The DQOs for representativeness will be assured through collection of a representative sample in the field using approved sampling SOPs and selection of a representative aliquot by the chemist in the laboratory for analysis. The DQO for completeness in regards to collection of samples at identified sampling points and successful analysis of collected samples resulting in usable data as assessed using EPA Region 3 data validation guidelines is 100%. Sampling points which cannot be sampled due to field conditions, or data determined to be unusable upon validation will result in assessment of the impact on the data set. The DQO for comparability is to ensure that the data generated will be comparable to other dioxin data generated and to health related benchmarks. This will be assured through collection of the samples using approved sampling SOPs and analysis of the samples using EPA Method 1613B. 7) Should data be reported using reporting limits (method specified minimum levels) or sample specific detection limits? Detection limits shall be as specified in Method 1613B, at a minimum. Concentrations of PCDD/PCDF isomers shall be reported at or above the "minimum level" for each sample. Isomers identified below the "minimum level" shall be reported by the laboratory and appropriately qualified as such for each sample. Detection limits are to be reported for isomers not identified in each sample. 8)Should furan results be reported? Results for both dioxin and furan isomers as specified in Method 1613B must be reported. 9) Should homolog totals be reported? Total dioxin equivalents (TEQs) shall be reported for each sample based upon the 1989 Interim Scheme ("Interim Procedures for Estimating Risks Associated with Exposures to Mixtures of Chlorinated Dibenzo-p-dioxin and -Dibenzofurans (CDDs and CDFs) and 1989 Update (EPA/625/3-89/016), March 1989.") Results for each specific PCDD/PCDF isomer shall also be reported.
