Region IV. (2) Contractor -The party with which the EPA contracts for the services described in this solicitation. ' (3) Contract -The legally binding agreement between the EPA and the Contractor. (4) Site: FCX site located in Washington, North Carolina as described in Section 3.0 of this Statement of Work (SOW). (5) Thermal Desorption/Distillation is a treatment process that uses thermal energy to volatilize organic contaminates and water from soil and debris; The process must be conducteq in an inert and/or non-oxidizing atmosphere. Heating for this process may be directly, radiantly or indirectly supplied to the contaminated media to be treated. However, under no circumstances shall any fuel be combusted in the presence of .the contaminated media. Use of either high or low temperature systems to accomplish these objectives is acceptable. The Thermal Desorption/Distillation system must have a recovery or nondestructive air pollution.control system; an afterburner, fume incinerator, or thermal oxidation system will be unacceptable. (6) Inert and/or non-oxidative atmosphere -For the purpose of this contract "inert and/or non-oxidizing" atmosphere shall mean an atmosphere inside the treatment system with an oxygen concentration of less than 5.0% by volume. (7) Radiantly heated shall mean the use of any non- conductive, non-conv~ctive heating source. ( 8) Directly heated shall mean the use of hot gases to convectively heat the contaminated media. However, this must be distinguished . from directly fired technologies. Any technology which allows for the presence of a flame and/or combustion in the presence of the contaminated media shall be considered to be directly fired. Directly fired treatment technologies will not be considered for use for this project. I I I I I I I I I I I I I I I I I I I (9) Independent Laboratory -A laboratory that is not owned, operated, organizationally or otherwise financially connected to the contractor, ' (10) A Low Gas Flow System shall mean any thennal desorption technology that uses minimal amounts of carrier gases such that the total flow of non-condensable gases exiting the desorption chamber is less than 500 DSCFM. This will be tested by a measure of the gas flow rate exiting the system condenser at 0 celsius. 1,2 INTRODUCTION EPA Region IV is currently undertaking Removal Actions to abate an immediate threat to human health and the environment at the FCX-Washington Site, located in Washington, North Carolina. The Site is listed on the Agency's National Priorities List (NPL), and is currently undergoing a Remedial Investigation/Feasibility Study (RI/FS). As part of the on-going removal activities, EPA Region IV plans to initiate the on-site treatment of approximately 14,700 cubic yards of waste pesticides, and pesticide contaminated soil and debris. EPA is requiring the contractor to use on-site thermal desorption or thermal distillation technology to treat the contaminated material (soil, waste pesticides) to the standards specified i~ Section 3,2, Waste Profile and Clean-up Objectives. For purposes of this statement of work, thermal desorption is not: incineration (a,k,a.-thermal oxidation), directly fired desorption, and/or technologies with direct high volume air-stack discharge, (either the system must be a low gas flow system or i,e,1 90% of all carrier gases must be recycled to the system). Alternative technologies, including but not limited to offsite Transportation and Disposal, will not be considered for award, Site conditions are the result of an abandoned pesticide formulator. The operations covered approximately _five ( 5) acres of land located in a lightly populated residential area. Approximately 14,700 cubic yards of material have been excavated and are stockpiled on-site. 1.3 CONTRACTOR SERVICES TO BB PROVIDED The Contractor shall proviie the following remediation services at the site: ( 1) Mobilize and operate the thermal desorption/thermal distillation unit at the site. (2) Sample, composite, and analyze the waste to develop a treatment profile. The contractor shall be responsible for all sampling and laboratory analyses to confirm that the clean-up 2 I I I I I I I I I I I I I I I I I I I 3 objectives have been met. All sampling and analysis shall be done in accordance with OSWER Directive 9360.4-01, Guidance for Removal Activities, Sampling QA/QC Plan and Data Validation Procedures (April 1990), EPA/540/G-90/004, and ~ Environmental Compliance Branch Standard Operating Procedures and Quality Assurance Manual, February 1, 1991, US EPA Region IV, Environmental Services Division. Both documents can be made available upon request of the Project Officer. An independent laboratory shall be used to analyze all samples. All contractor sampling and subsequent analysis under this contract shall be subject to EPA review. EPA reserves the right, at any time, to take split samples or provide blank or spike samples for contractor analysis at no additional cost to the Government. The Contractor should be prepared to receive and analyze up to two each blank and/or spiked samples received from the Government at any time during the contract period of performance. The EPA also reserves the right, at any time, to audit the contractor's selected laboratory at no additional cost to the Government. If any of the above actions indicate that the contractor and/or its selected laboratory are not following: a) the contractor's approved Sampling and Analysis_ Plan (reference Attachment B, Section 1.3); · b) EPA method 8080; c) Sampling and Analysis protocol stated above in this section;' the . contractor shall take immediate steps to rectify any discrepancies identified by the EPA or the contractor at no additional cost to the Government. In rectifying such discrepancies, the contractor may be required to analyze additional samples at no additional cost to the Government. (3) Contractor shall compile and analyze all necessary data to meet Government reporting requirements. Contractor shall provide reports as described in Attachment B. ( 4) Contractor shall size the material based on their selected treatment s•ystem. Contractor shall perform all services necessary for the operation of the treatment system including, but not limited to: estimation and treatment of all contaminated materials, site preparation; identification and connection of all necessary utilities; submission of required plans and reports; mobilization and demobilization of the unit and site personnel; removal and handling of stockpiled contaminated soil; unit design; all materials handling required for the proper operation of the treatment syste~; feeding and screening of the contaminated soil; handling, I I I I I I I I I I I I I I I I I I I 4 segregating, and tracking processed soil pending analysis i and retreating material as necessary to meet stand~rds as defined in Section 3.2. After contractor sampling demonstrates that soil meets the cleanup standards in Section 3.2, the contractor shall deposit the processed soil on the site in an area designated by EPA. The contractor shall perform site restoration as required by 1. 3 ( 15 )'. (5) Perform a demonstration of the actual treatment system that will be used to process all contaminated materials at the site, in accordance with a plan approved by the EPA. The Contractor must start the demonstration no later than~ 45· calendar days after EPA's approval of the demonstration plan. The Contractor shall use the same treatment system which successfully. completes the demonstration for the ac.tual treatment of the remaining soil. De-mob or substitution of the successful demonstration system is prohibited. In the demonstration, the Contractor shall process waste that is representative of the contaminant mass on-site, and achieve soil clean-up . objectives as aefined in Section 3. 2. The Contractor's selection of waste that is "representative of the contaminant mass" shall be presented to and approved by the Government in the demonstration plan prior to the commencement; of the demonstration. The demonstration should handle at least 100 cubic yards of the waste material, but shall not exceed 1500 cubic yards. ll shall prove the treatment system can achieve all of the appropriate'treatment criteria andlor standaras for any by- product streams. The demonstration shall prove tliat anyair pollution control devices function properly, and can be monitored appropriately. Once contaminated media has been introduced for treatment during the demonstration, the demonstration must be completed within 28 calendar days. The contractor shall monitor and test for a minimum of the following parameters during the on-site demonstration: ....,.stack Sampling-HCL; Particulates; voes; Semi-VOCs: Total r pesticides (EPA method 8080); Dioxins; Furans; Moisture; and Gas volume. Continuous Emisslon Monitoring-Total Hydrocarbons; GaFeeR HeneniEle1 SarSen dienideJ and Oxygen. Soil Sampling-Total pesticides, Dioxins; Furans; Semi- VOCs; Total RCRA metals; TCLP metals. The establishment of proper operating conditions ·through the site demonstration, and the establishment of proper control monitorir.g is essential for all aspects of the treatment unit. For example, if a gas-phase carbon adsorption system is to be I 5 I I I used in the air pollution conti::ol system, the Agency will require the contractor to suggest proper operating parameters and limits (such as gas temperature and moisture content in the carbon) for the system, To allow ·the contractor flexibility in designing and operating the treatment system these parameters will not be dictated by the Agency in this Statement of Work, However, the contractor must demonstrate at all tl.J!leS that all aspects of the system can be properly· monitored, and that proper .operating conditions can be maintained in the treatment system. Any variation, deviation, or excursion outside of· proper operating condi tJ_ons_(.as I established in the demonstration) sliall result in the use of . o ---the automat-ic wastefeecisnutoff. (AWFSO). ~ I . I I I I I I I I I I I I I After successful completion of the demonstration, the range of operating limitations and AWFSO, operating limits for the treatment unit and air pollution control system (i.e. oxygen levels, minimum temperatures, residence times, mass feed rates, gas flow rate in treatment unit, gas flow rate in air pollution control system, etc.) will be recommended in writing by the Contractor as described in Attachment B, Section 1.2.2. ( 6) After successful completion of the demonstration, and after the EPA Project Officer (PO) receives and approves_ confirmatory laboratory analyses tpat show the contractor has met the soil clean-up standards defined in Section 3.2, the PO will issue a written Notice To Proceed. This notice will: a. authorize the contractor to begin full-scale treatment of the on-site waste; b. set the operating parameters that will be used by the contractor at all times during the full-scale treatment. (7) During the full-scale treatment of the contaminated media the contractor shall continuously monitor, at a minimum, the following: Continuous Emission Monitoring-Total Hydrocarbons; SaJ::bea meae:Hide1 Garbea eiienidef and Oxygen. ( 8) During the full-11cale treatment of the contaminated media . the contractor shall provide weekly summaries on the progress of the remediation, and the previous sampling and analysis (See Attachment B, Section 1,5), (9) The Contractor shall minimize the discharge to the atmosphere of any gas and/or vapor stream that has been in contact with the contaminated media, At least 90% of all carrier gases must be recycled to the treatment system and collected after treatment is completed, unless a Low Gas Flow System is used. A low gas flow system must continuously have I I I I I I I I I I I I I I I I I I I 6 a non-condensable g_as flow rate of less than...5.00-D.S.CF.H,. All volatilized water and contaminants· shall be either: treated further in the vapor phase and condensed; condensed and then treatec,l; or simply condensed directly for shipment to an off- site treatment facility. Water may be separated and discharged from the treatment system, but only if it has been properly treated in accordance with section 2.1.3, CWA compliance. It is suggested by EPA, but not required, that any collec·ted water be mixed with the treated soil so as to provide dust suppression. If this is the route chosen by the contractor the water must be added to the treated soil prior to confirmational soil sampling to ensure that the addition of the water does not re-contaminate the treated soil. If it is necessary to bleed off gas from the carrier gas stream the following conditions must be met: . a. The gas must be condensed to a temperature less than ~ 0 degrees Celsius, with any liquid condensate being either returned to the treatment system or collected separately. b. The gas flow rate of the vented gas cannot exceed 10.0% of the flow rate of the carrier gas stream at any given time. If the carrier gas is to~ be vented at times when the treatment system is not operating, then the mass of gas discharged shall not exceed 10.0% of the mass of gas in the carrier system. As an alternative to this limit for low gas flow systems, the' total discharge of non- condensible gases exiting the desorption chamber must continuously be less than 500 DSCFM. c. All carrier gas vented from the system must meet the criteria specified in section 2.1.4, CAA compliance. . ( 10) Using thermal desorption or thermal distillation as defined in 1.1(5), the Contractor shall successfully remove from the soil and debris all contaminants to meet the clean-up objectives in section 3. 2. Once soil has been processed through the treatment system it shall be stockpiled in an area on site near the treatment ·unit as designated by the Government's PO. The•contractor shall collect and segregate the treated soil in either 500 ton or daily lots (whichever the contractor finds more convenient) for sampling to insure compliance with the. treatment standards found in Section 3.2. If the soil fails to meet the required treatment standards, it shall be processed until it meets said standards at no additional cost to the EPA. ( 11) The Contractor shall dispose of ·all process residuals (e.g., decontaminated water, contaminated work-clothes, the I I I I I I I I I I I I I I I I I I I 7 soil bags, etc. ) and all non-treated material in a manner consistent with RCRA regulations (as applicable). Offsite shipments of hazardous substances must comply'with 42 U.S.C. Section 962l(d)(3) and the following rule: Amendment to the National Oil and Hazardous Substances Pollution Contingency Plan: Procedures for planning and Implementing Off-Site Response Action: Final Rule 59 FR 49200 September 22, 1993, codified at 40 CFR Section 300.440. If practical, various debris, such as the soil bags or pesticide containers may be processed through the treatment system and disposed of as non- hazardous material. This is assuming that sampling indicates that the material has been treated and meets the standards specified in Section 3.2.2. (12) The Contractor shall establish and maintain continuous site safety and security while engaged in treatment operations in accordance with the OSHA standards found at 29 CFR 1910.120. (13) It is the contractor's sole and exclusive responsibility to provide utilities to the site and to properly dispose of all effluent streams from the site.

The area is lightly populated, with roughly 600 residents living within a one-mile radius of the Site. Washington is located on the North Carolina coastal plain and lies along side the Pamlico River. The Site is presently owned by Fred Webb Grain Company, and is operated as a trucking distribution and storage facility. The Tar River, a tributary of the Pamlico, borders one side of the Site. The wetlands of the Tar River are within the influence of the FCX site. The FCX facility operated from 1945 until the early 1980's as a pesticide storage and blending facility for distribution to local farmers. The pesticides most prevalent at the Site consisted of the chlorinated organic p~sticides chlordane, methoxychlor, DDT, and DDE and various other chlorinated and non-chlorinated organic chemicals used-to mix and blend pesticides. The Site was permanently closed and the buildings and warehouses were cleaned out. The majority of the property was sold to Fred Webb Grain for use as a grain storage facility. During operations as FCX, the facility routinely buried expired and waste pesticides in on-site disposal trenches. Prior to the closing of the facility, residual waste, including pesticides and I I I I I I I I I I I I I I I I I I 12 contaminated debris were also buried in a trench on-site. The trenches were located between the warehouse (currently leased by Fred Webb Grain to a trucking company) and the Tar River. The Site is generally open and readily accessible to the public. The trenches were located approximately 100 feet east of the grain warehouse. The trenches and storage area are bordered on the three other sides by farmland which is not owned or controlled by Fred Webb Grain. Immediately behind the narrow section of farmland is a woodland swamp and the Tar River. FCX-Washington has been ranked as an NPL Site based upon the potential for possible groundwater and surface water migration. The NPL score is 40.39 which resulted in the ranking of the site as number 449 on the list. See 40 Code of Federal Regulations Part JOO, Appendix B, Group 9. · 3.2 Waste Profile & Clean-up Objectives 3.2.1 Waste Profile In 1986, the North Carolina Department of Human Resources (NCDHRL sampled the Site. The Site trip report provided with the NPL ranking package indicated the sampling consisted of only surface sampling, from Oto 2 inches in depth. The data provided indicated the presence of: Pesticide Aldrin Chlordane DDT, DDE \Me~~=X..

The chemicals were apparently used as mixing, blending or solvents in pesticide formulations. Organic analysis indicates there are nineteen (19) total compounds in the scan. The families of compounds consists of chlorinated, phosphorylated, carbamated sulfur based and .various unknown or unidentified compounds at concentrations ranging from 1. 0 ppm to 19. 0 ppm. Although the above contractions may not appear to be extremely high, the samples were obtained from a small specific portion of the trench. Since the trenches were not homogeneous, the analysis should be used to indicate the types of materials present and not necessarily the highest levels which may be encountered. A more complete set of sampling data generated during the soil excavation can be found in Exhibit A to this Statement of Work. Some of the pesticides or compounds listed above are also listed hazardous waste under 40 CFR 261, Subpart D, and all are listed hazardous substances under CERCLA Section 101(14). 3.2.2 Clean-up Objectives The.contractor shall ensure that the treated soil_has a total pesticicie concentration (P.er EPA method 8080-organo. chloride pesticiaes and PCBs) of egual to or less tlian 170"nig7Jcg. Tlie contractor snall conf-irm this in the fol"lowing manner: from-either the daily or 500 ton lots (see section 1.3(10)), three independent grab composite samples shall be taken over the entirety of the lot. Each of these three samples must be below 1.0 mg/kg total pesticides (see above) for the lot to be considered successfully treated. · • I I I I I I I I I I I I I I I I I I I date: May 6, 1994 14 ATTACHMENT B.l REPORTING REQUIREMENTS 1.0 Reports and Plans The Contractor shall compile and analyze all necessary data to meet Government reporting requirements.

Offerers are also reminded that submission of an offer constitutes acceptance of all solicitation terms and conditions, unless exceptions are specifically identified by offerer. Your attention is directed to FAR 52.215-16, Contract Award, which is incorporated by reference in Section L.l of this solicitation. 5. All other terms and conditions remain unchanged. • I I I I I I I I I I I I I I I I I I I TQl ANS TQ2 ANS TQ3 ANS TQ4 ANS My question, then, is to ask whether the bidders can be told why the choice of technology required such a tight limitation? As is the Agency prerogative in carrying outr its statutory mandates under CERCLA, the decision was made to be selective in the type of thermal treatment technology to be used on this project. Section B.2-Under the Supplies/Services column of Schedule,-it is stated that "necessary services include, are not limited to: estimation and treatment of contaminated materials •••• ". What is meant by the estimation" in the above phrase? the but all word The contractor is responsible for verifying to its own satisfaction the amount of material to be treated on-site, the type of soil, particle size distribution, and any other parameters about the contaminated soil which it needs to effectively design and operate its treatment system. Section B.2., -' Under the Supplies/Services column of the Schedule, it is stated• that the scope of work includes screening of the contaminated soil. What should be done with debris and/or large rocks screened out of the soil prior to treatment? If the debris and rocks screened from the soil can be verified free from contamination under the RCRA "contained in policy" they would not be considered hazardous waste. If this is the case they can be piled with the other debris to the south of the current stockpile. However, the contractor will be responsible for the off-site disposal of contaminated debris. The Project Officer will coordinate with the contractor to obtain an off-site land ban variance (pursuant to 40 CFR 268.44) for landfilling. Section B.2 •• , If the actual volume of material to be processed exceeds the estimated volume (14,700 cubic yards), will Contractor receive payment for the additional material processed? No. This is a fixed price contract. The volume estimate of 14,708 cubic yards is based on an in place survey of the stockpile done in .January 19 9 2, a tracking of the soil excavated through January 1993, and a count of the bags. This estimate also includes up to six inches of any contaminated soil lying directly below the stockpile which must be excavated and processed. Each bidder is responsible for determining their own computation for bidding purposes. 1 I I I I I I I I I I I I I I I I I I I TQS Section L.11: It appears that the technical question period will expire before the site walks are complete. Is that correct? · , ANS The deadline• for technical questions was extended to April 22, 1994 by amendment one of the solicitation. TQ6 Section L. 16: This section specifies items to be submitted as part of the offerer's proposal. There does not appear to be a requirement for submittal of technical information regarding the offerer's thermal desorption/distillation processor or offerer's approach to the FCX Site cleanup. Should the proposal include this information? If so, is there a specific format for presenting the information which should be followed? Should a complete technical proposal be prepared detailing how the offerer will meet the process·specifications and perform the work?. ANS The bid submittal should be price only, the Agency will then evaluate the low offerer for technical and contractual responsiveness. If that offerer proves non-responsible, the Agency will move to the next low, responsible offerer. TQ7 Attachment A, Section 1.3(17)/i): Does the EPA have sample results for each of the 300 square foot areas mentioned in this section (page 7 of the Statement of Work) indicating that- the areas are presently clean, that is, that they contain no concentrations greater than the total pesticide removal action level of 1.0 mg/kg? If so, will the results be provided to the offerers prior to the submittal of the proposal? We are concerned that Contractor may be required to remove and process soil from these areas that were impacted by pesticides prior to Contractor's site activities. ANS This section refers to only the areas where the contractor chooses to set up its equipment and operate, which within the confines of the Site has been left to the contractor's discretion. The Agency does not expect the contractor to sample non-active areas of the Site, nor excavate additional soil from these areas. The contractor may sample any area prior to the installation of its equipment to verify pesticide levels. The contractor is to remove all contamination resulting from its own operation • • TQB Attachment A, Section 2. 0: Will the Contractor be required to file for.a State or Federal air permit? ANS No. See 40 CFR 300.400(e). TQ9 Attachment a, Section 2.2: What other state regulations have been·identified as being potentially applicable or relevant and appropriate for the FCX Site remediation? The statement 2 I I I I I I I I I I I I I I I I I I I regarding meeting State regulations is broad and could represent a significant contingency item for the bid. ANS The answer to this question will vary from, one treatment system to another. Permits common to most operations, CAA, RCRA, and CWA were identified in the SOW. In addition the Agency requires full OSHA compliance on-site. As to other requirements that may be applicable the Agency is relying on contractor's knowledge of its particular treatment system. As this is a Federal CERCLA removal action no on-site permits are required (40 CFR 300.400(e)) and ARARs are limited to the requirements of 40 CFR 300.415(i). TQ10 Attachment A, Section 3.2.1: The tabulated site data indicate that debris is present in the trench material. Is any information available on the amount and type of debris present in the bagged and stockpiled material? Also, is any information available on the particle size distribution of the soil to be treated? ANS No information is available as to particle size distribution. Information as to the debris is anecdotal, and should not be taken as a guaranty of conditions in the pile. During the last series of excavations an attempt was made to hand remove most pieces of debris bigger than three feet long or so. Not much· was removed, and there did not appear to be a lot of- other debris in the soil. We estimate that less than 3% of the material in the stockpile is larger than two inches. TQll Attachment A, Section 3.2: No data on soil moisture content or recoverable organic ( i-e., Oil and/or Total Petroleum Hydrocarbon) content of the soil were found in this section or in Exhibits A-1 and A-2. These parameters can have significant impact on thermal treatment costs. Providing these data to the offerers will result in a uniform basis for the bid so that all bids may be judged on an equal basis. ANS This information is not available. TQ12 Attachment B, Section l.l.3{2){a): A requirement is included that the feed rate be monitored with+-0.5% accuracy, and that the feed rate be interlocked with the automatic waste feed shutoff (AWFSO) system~ Unlike an incinerator, in our thermal desorber, the•feed rate has no direct relationship to air emissions, because the carrier gas is condensed and recycled to the. desorber, The only potential negative consequence of overfeeding the desorber is that the treated soil may fail the treatment standard. This would be identified by quality control sampling of the treated soil and would not represent an off-site exposure risk. The requirement to accurately monitor the feed rate and tie it to the AWFSO system adds considerable complexity to the feed 3 I I I I I I I I I I I I I I I I I I system and will reduce the on-line factor for the processor. This added cost results in no benefit to the project and in no added protection of human health and the environment. Please delete this requirement and replace it with a requirement for the contractor to .monitor the total mass of waste feed (or treated soil) for billing purposes. ANS The feed rate does not have to be wired into the AWFSO if the contractor can provide a suitable alternative, such as chamber temperature, pressure, and/or oxygen level. Also, the feed rate need only be monitored to +-5.0%, not 0.5%. The SOW will be modified to reflect these changes. TQ13 Is pyrolysis remediation technology an acceptable to address the Farmer's Cooperative Exchange Washington, Beaufort County, North Carolina? alternative project in ANS See paragraph 1.1 of the SOW for definitions of allowable and unallowable technologies. TQ14 We have some questions in regards to the Attachment "A ", Statement of Work, Item L 1. 5. This relates to the thermal desorption and distillation treatment of the volatile organic contaminants and water from the soil and debris. You indicated that.this needs to be done in a non-oxidizing atmosphere. WQ are a manufacturer of industrial burners, fume incinerators,- liquid waste burners, and gasifiers but we do have a concern about how the volatile materials come off the process, there is no indication as to how you are suggesting that to be handled. You have indicated that it cannot be handled by an afterburner or an incinerator system, so we are at a loss as to what we are going to do with that material. We don't have a problem maintaining a 5% by volume oxygen but when the volatile materials and the exhaust come off the process, what is to be done with that? ANS Proposals for systems that utilize an industrial burner, a fume incinerator, or liquid waste burner will be ·determined non-responsive in accordance with SOW paragraph 1.1. As to what to do with the collected contaminants please refer to Section 1.3, paragraph 9 of the Statement of Work. TQ15 On Item 1.2, Introduction, Second paragraph, you indicated that 90 % of all car5ier gases must be recycled through the system. I would think that one should be really concerned about that because the concentration of the gases are going to go up above the 50% of the lower explosive limits and it would appear· that if one was to get any oxygen into the system you might have a serious explosion. Please explain what you mean by this. ANS The requirement is that at least 90% of the volume of the 4 I I I I I I I I I I I I I I I I I I I carrier gas be recycled. Any volatilized contaminant phase is to be condensed and removed from the carrier gas; refer to Section 1.3, paragraph 9 of the SOW. , TQ16 Reference Attachment A, Statement of Work, Sections 1.3.5 and l. 3. 7: The RFP requires that carbon monoxide and carbon dioxide be monitored continuously during both the demonstration test and the full-scale treatment. These are critical control parameters for the operation of an incinerator because.there is a correlation between them and the destruction of the hazardous compounds prior to emission to the atmosphere. However, in a thermal desorber with condensation and carrier gas recycle, CO and CO2 have no significance with respect to air emissions of hazardous constituents. Rather, the condenser outlet temperature and carbon absorber outlet concentration are the critical control parameters. . Furthermore, CO · and CO2 are not hazardous air pollutants and do not need-to be monitored for any other reason but to control a combustion process. No combustion of any form occurs in our thermal desorber and we have not been required to monitor either of these parameters in previous projects. Please delete the requirement for CO and CO2 monitoring for thermal desorbers that do not perform combustion of the waste or have combustion of any type in the presence of the soil anywhere in the treatment unit. ANS The SOW will be modified to delete·the requirement to monitor CO and CO2. TQ17 Reference Attachment A, Statement of Work, Section 1.3.6: What period of time should be assumed by the contractor to elapse between the submission of the recommended full-scale operating parameters and the receipt of the notice to proceed? We will have a fully mobilized crew and the associated daily site expenses at this time, and need to properly budget for this scheduled delay. We would like to recommend that the conditional approval be contained in the approved demonstration test plan, provided.that certain control limits are met during the demonstration test and that the confirmatory analytical results are received and submitted to EPA. This would reduce both our and EPA's cost, and remove a significant budgetary contingency item. ANS SOW paragraph l. 2. 2 has been changed. The Agency will respond to the recommended operating parameters within one week upon receipt •. It is the contractor's prerogative to submit any innovative suggestions in the demonstration plan. At a minimum the plan should have pre-set parameters which are met during the demonstration and ·require that verification samples of the treated soil (meeting all QA/QC requirements) be in the contractor's possession.· 5 I I I I I I I I I I I I I I I I I I I TQlB Reference Attachment B. 1, Reporting Requirements, Section l.l.3.2(b): The operating temperature of the primary and secondary combustion chamber in an incinerator .is a critical performance parameter with respect to preventmg undestroyed contaminants from being emitted to the atmosphere. For this reason, these chambers' temperatures are automatic waste feed shutoff (AWFSO) parameters. However, the operating temperature of a thermal desorber has no similar requirement for this feed permissive, since combustion does not occur in the presence of the waste .or the soil anywhere in the treatment system. The consequence of operation of the unit at lower than optimal dryer temperature is that there is a potential for soil to be discharged that does not meet the treatment standard. This would present no emissions problem and would be caught by the quality control sampling of the treated soil. For a thermal desorber that condenses the · contaminants and recycles carrier gas, the temperature that. should be interlocked with the feed is the discharge temperature from the condensing system. If this temperature is exceeded, the contaminants could be emitted with reduced control to the environment. Please delete this requirement for thermal desorbers that do not perform combustion of the waste or in the presence of the soil anywhere in the treatment unit. ANS Monitoring the temperature in the d_esorption chamber is one of- the few ways of actively monitoring the performance of the treatment system with minimal time lag. In addition, monitoring the temperature and tieing it to the AWFSO provides for the safer operation of the unit. This requirement remains unchanged. TQ19 Please elaborate on what air pollution control system equipment shall be required in order to meet the Maximum Achievable Control Technology (MACT) standards (Sec. 2.1.4) •• ANS The Agency is not specifying any particular air pollution control technology, except to exclude afterburners, secondary combustion units, fume incinerators, thermal oxidizers, and other direct-fired technologies, and to require that gas exiting the desorption chamber be condensed. The EPA Region IV Air Compliance Branch will be evaluating the contractor's air pollution control system using MACT criteria to determine if the system is apprtlpriate. TQ20 Please consider direct flame as a feasible option for thermal desorption as temperatures can be controlled and monitored continuously. ANS In accordance with SOW 1.1, any direct-fired technologies will be determined non-responsive to the solicitation. 6 I I I I I I I I I I I I I I I I I I I TQ21 Is the carrier gas considered an inert vehicle separate from the volatile fraction of the waste? ANS Yes. TQ22 Can the light organics be consumed as fuel supplement after passing through the gas treatment/recovery system? ANS No. TQ23 Paragraph 1.3 (4), p.3 a. Is Contractor required to provide any office, sanitary facility and/or other support facilities for the EPA on-site personnel? If yes, please specify exactly what will be required. ANS No. b. Are there any 'restrictions that would hour/day, 7 days/week operation? If so, conditions and exceptions. ANS No. TQ24 Paragraph 1.3 (9), p. 5-6 prohibit please a 24 state a. Is the -20@ Celsius condenser a requirement if the Contractor can use other methods to meet air discharge specifications? ANS There is a requirement to condense the gas leaving the desorption chamber. However, this requirement in the SOW has been modified to condense to a temperature of 0 Celsius. b. The specifications require that at least 90% of all carrier gasses must be recycled to the treatment system and the gas flow rate of vented gas cannot exceed 10% of the flow rate of the carrier gas stream. Does this mean that 90% recirculation of 25000 CFM system (i.e. 2500 CFM discharge) is acceptable but a 200 CFM system cannot discharge more than 20 CFM? If so, what would be the rationale for such requirement? Is another measure (e.g. maximum discharge gas flow rate) more appropriate? • ANS The Statement of Work will be modified to allow for systems that can be operated so that less than 500 CFM will be discharged after condensing. These "low flow" systems will not require gas recycling. Low flow systems will be specified as an alternative to the gas recycle · requirement. The requirement to limit oxygen to 5.0 percent and to condense the gas exiting the desorption chamber remains unchanged. 7 I I I I I I I I I I I I I I I I I I I TQ25 Paragraph 1.3 Cl0l, p.6 a. This paragraph refers to debris. What type (e.g. wood, brick, steel, glass, plastic, etc.), s_ize aa.d quantity of debris exists in the contaminated media to be treated by the Contractor? ANS No information is available as to particle size distribution. Information as to the debris is anecdotal, and should not be taken as a guaranty of conditions in the pile. During the last series of excavations an attempt was made to hand remove most pieces of debris bigger than three feet long or so. Not much was removed, and there did not appear to be a lot of other debris in the soil. We estimate that less than 3% of the material in the stockpile is larger than two inches. b. What are the specific requirements for "treated" material stockpiling? How far is the EPA designated stockpile area from the treatment unit. Will the treated material have to be trucked there? Is the treated material required to be stockpiled on liner? If so, what type of liner is acceptable? Does the run-off from the stockpile need.to be collected and treated? Does the treated material stockpile need to· be covered? ANS It is presumed that the treated ~oil will be stockpiled as close to the contractor's treatment system as possible without interfering with the treatment operations. The treated soil stockpile area will be on-site. The method of transportation is left to the contractor. The soil does not have to be stockpiled on a liner, but the contractor is. responsible for dust suppression from a particular pile until the conformational sampling is returned and the pile verified clean. Run-off control is not required for the treated soil stockpile, as the contractor will be sampling the area after the project is completed. TQ26 Paragraph 1. 3 Clll, p. 6 Will EPA sign all required documents, (manifests, bill of lading, etc.) for all materials shipped off-site for disposal and/or recycling? Is the debris located outside the fence and south of the contamilllilted soil stockpile to be disposed? ANS Yes. No. TQ27 Paragraph 1.3 (12), p.6-7 What are the specific. security requirements while the treatment operations are conducted? Examples include fencing, type . of fencing, signs, log-in/ log-out procedures, 24 hour 8 I I I I I I I I I I I I I I I I I I security guards, etc. ANS Specific security arrangements are left up to the contractor, although RCRA and OSHA security requirements to restrict access to hazardous· waste treatment facilities are applicable. The Agency concern for security is only to the extent that the public be protected from hazardous areas, and that reasonable entry and exit procedures are in place. The contractor is responsible for securing its property and equipment against threats snch as theft and vandalism. TQ28 Paragraph 1.3113), p. 7 What specific local and state approvals, licenses, permits and/or consents are required to operate the thermal desorption or thermal distillation treatment process? Please note that paragraph 1. 3 ( 13) requires Contractor to. obtain local permits for constructing and operating the treatment system while Paragraph 2 .1 states that no permits are required for any on-site operation. ANS In reference to 40 CFR 300.400(e) no on-site permits of any type are required. However, it is likely that the contractor will have to perform some activities that are not "on-site". For example, if the construction of a waterline, or power hook-up requires a permit to have the utility brought in from off-site then the contractor is responsible for obtaining that permit. TQ29 Paragraph 1.3 115), P.7 What specifications (e.g. compaction requirements), if any, need the Contractor follow for any backfilling activity? For seeding? For other site restoration activities? What is to be the disposition of the fence and HOPE cover and liner from the existing contaminated material stockpile? ANS Reference 1.3(15): The site shall be restored to its original condition prior to mobilization. The fence can be left in place or will be. disposed of by EPA. The current stockpile cover will · also be disposed of by EPA at the end of the project. · TQ30 Paragraph 1.412), p.f!' Can the EPA provide the survey data used to determine the size of the contaminated soil stockpile? · ANS Yes, the survey and data on soil added after the survey are attached to this amendment. See technical question 4. TQ31 Paragraph 2.1.1, p.9 9 I I I I I I I I I I I I I I I I I I I The regulations referenced in this section apply to _fixed based hazardous waste treatments, storage and disposal facilities. The intention at_ FCX site is to use a mobile treatment unit. In addition, the contract d6es not include any post-closure activities. Are the remediation activities at FCX site subject to all of the referenced RCRA 40 CFR 264 regulations? If not, which specific regulations apply? ANS The RCRA regulations referenced in this section are those that may be applicable, and will obviously vary from unit to unit. See Revision A to the Statement of Work. TQ32 Paragraph 3.2.2. p. 13 ANS ANS a. Is there test data showing that 1 _ the soils is achievable? Are achieve this target? ppm total pesticides in additives required to _No site specific treatability However, all offerers are required up objective. studies were conducted. to achieve the 1 ppm clean- b. Have dioxin analyses been performed on the stockpiled soils? What were the results? Will they be required on the treated material to be left on-site and/or materials to be taken off-site? Dioxin data was generated during the Agency's RI/FS conducted at the Site. All reported values were below 1,0 ppb Total Equivalents. The only dioxin sampling required for this project is during the demonstration, for purposes of showing that the treatment system in question does not generate any dioxins. No dioxin sampling is required during the full scale treatment. TQ33 Will U.S. EPA provide us with a list of the companies who received the Solicitation? ANS Yes. Any other vendors desiring this list should direct their requests to Christina Maddux. TQ34 Reference Attachment A, Section 1.3(2) of the Solicitation: What are the data validation requirements? Will EPA Contract Laboratory Proceduri!s (CLP) or similar analysis and data reporting procedures be required for the soil analyses? ANS The use of a CLP laboratory is not required. The data validation pro_cedures required for this project are outlined in the two references that were cited in this section, TQ35 We request that EPA provide the data on which the soil treatment volume estimates are based. 10 I I I I I I I I I I I I I I I I I I I ANS See technical question 4, TQ36 Reference Attachment B,l, Section 1,1, It appears that this section requires the work plan to meet the requirements of 40 CFR 264 Contingency Plan, Closure Plan, Financial Assurance for Closure, and Liability Requirements. These requirements are typically associated with a RCRA Part B permit and may not be applicable for the short removal action. However, the requirements as worded would result in additional cost to EPA for preparation of the work plan. In light of this, please consider removing or revising these requirements. ANS See Revision A to the Statement of Work. The contractor shall be required to meet all applicable, appropriate and required Federal regulations specific to the contractor's proposed process. With respect to LOR, EPA will waive the LOR for on-. site placement. TQ37 Reference Part I: The Schedule B.l, B.2; Attachment A, 1.3 Contractor Services To Be Provided, ( 5) -The B. 2 Schedule does not mention the demonstration listed in Attachment A, 1. 3 Contractor Services To Be Provided, ( 5) • If this demonstration paid for by EPA? If this demonstration is not successful within the allotted 28 Calendar day period, what options are available to the contractor? ANS When the contractor submits his offer, he must submit a lump- sum price for all of the effort called out in the SOW and attachment B.2. If the demonstration is not completed within 28 days the contractor will be in default of the contract. Your attention is directed to the Default clause at FAR 52.249-8. TQ38 Reference: Attachment A, 1.3 Contractor Services To Be Provided, (5) -During the on-site demonstration, how many stack samples does the EPA desire to demonstrate the treatment system can achieve all of the appropriate treatment criteria and/or by-product streams?

Dust suppression of the treated soil is not required after the soil has been confirmed clean. Dust levels must be kept low . enough to provide for safe operation of equipment-and personnel. TQ41 Reference: Attachment A, 1.3 Contractor Services To Be Provided, ( 10) -For the temporary stockpiling of treated soils on-site, it has been indicated that the City of Washington will remove the treated soils following receipt of analytical data ·indicating the soil meets· the treatment standard. Given the limited available space at this facility, where does the EPA intend to stockpile the 500 ton and/or daily lots of soil while awaiting analytical results? ANS Treated soils will be stockpiled on site by the contractor in a way that will not interfere with treatment operations or the operations of the co-occupant. TQ42 Reference: Attachment A, 1.3 Contractor Services To Be Provided, ( 10) In what · time frame does the City or Washington intend to remove the treated soil from the site? Who is responsible in the event the City of Washington fails to remove soils in a timely manner, and due to a lack of storage capacity for treated soils, the treatment system is slowed and/or shut down? ANS TQ43 ANS TQ44 The exact time frame for the removal of the soil has not been worked out with the city. However, the Agency does not intend for the accumulation of treated soil to hinder the project. In the event that the amount of treated soil appears to be hindering operations of the contractor or the other occupant of the site, the Agency will have the soil removed. Reference: Attachment A, 1.3 Contractor Services To Be Provided, (10); 1.4 EPA's Responsibilities, (4) -Based on the sampling and analysis of this soil in accordance with EPA directive, who is liable for this material, if at some point in the future soil!'s that passed testing and analysis procedures are found to contain contaminants?

The following questions arise from this situation: a. Is the inside of this warehouse considered a handling area? ANS If the contractor simply removes the bags of soil from the warehouse and moves them to its treatment unit then the answer is no. The Agency only expects the contractor to remove the bags and contaminated soil in the bags from the warehouse. We do not require that the contract do any further clean-up of the warehouse, nor any sampling. However, if one of the bags is ripped or spilled in the process of moving the soil out then the contractor will need to remove the spilled material. ANS ANS b. If the portion of the warehouse occupied by soil bags is considered a handling area, will the walls and ceiling require composite sampling for verification of non-contamination? No. c. If wooden portions of this building are found to. be contaminated, what decontamination methodology is required? And what are the required verification procedures for assessing non-contamination of po~ous media such as wood? Not applicable. d. Will air quality monitoring be required in the building during the removal of the soil bags? If so, how frequently does EPA desire monitoring of ambient air and at how many stations? · ANS The contractor is responsible for maintaining a safe work area in and around the bags for his personnel, and the need for air monitoring vs. proper respiratory protection is left up to the contractor. The Agency intends to conduct its own air monitoring on the other side of the partition from the bags to ensure the safety of the personnel working for Campbell Trucking • .. e. If the building requires decontamination, how much of this building does the EPJI want decontaminated? In addition, how will the presence of the resident trucking firm affect the operation. Will the contractor be required_ to monitor the side of the warehouse occupied by the trucking company? Who is liable in the event of a lawsuit from this firm due to disruption of their operations? ANS The EPA is not requiring decontamination of the building, and will.be responsible for air monitoring on the trucking company 13 I I I I I I I I I I I I I I I I I I I side of the warehouse. As long as the contractor adheres to the terms of the contract, the Agency will handle any such dealings with the trucking company or the public.

Please provide more details and clarify the difference between the required demonstration and a RCRA trial burn. In the demonstration plan, the contractor is allowed to propose a demonstration structure that it feels can sufficiently demonstrate the technology in the given 28 day time frame. This plan is subject to EPA approval before the Contractor may proceed with the demonstration. The contractor can use the time available prior to the demonstration for equipment shakedown, as long as. no contaminated soil is- processed. Since no on-site inci'neration is to be allowed nder this contract the RCRA trial burn requirements do not apply. The Contractor may model his demonstration after a RCRA trial burn. b. The demonstration requires soil testing. Is this influent soil (feed) or effluent soil (treated) or both? Both. TQ71 Will the BIF regulations apply? If so, please explain how. ANS No. Since no contaminants will be burned on-site the BIF regulations will not apply. TQ72 How will interim operation be handled? Will the contractor be allowed to proceed at 75% of demonstration burn throughput? Further, submittal of "final operating parameters in three days does not allow sufficient time for receipt of final analytical reports •. How will this be handled? ANS If the contractor would like to propose a conditional approval for interim operations it should be included in the demonstration plan ( see answer t6 TQl 7) • To allow the contractor more time, the SOW requirement for the submittal of operating parameters (Attachment B-1 paragraph 1.2.2) has been 17 I I I I I I I I I I I I I I I I I I I changed to 7 days. TQ73 Textual accounts and reports of early investigatory work note the presence of Mercury (Hg) and Copper (Cu). ,In the absence of data to the contrary, it is logical to assume that metals will be present in the soils. Further, Arsenic, Lead, and a large number of other metals typical of pesticide formulations could be present. With this in mind, the following questions are relevant: ANS a. Is data available showing concentration levels of metals in the soils? Yes. Metals data is available in the Agency's completed at the Site in the Spring of 1993. in the public record for the Site. RI/FS which was It is available b. Have any studies been performed to demonstrate or predict the metal concentrations in the treated soil following thermal desorption? ANS No. c. Will the treated soils be tested for metals dur·ing operation ( see question b)? If so, what contingencies are. planned, if the treated soils show unacceptable metal levels~ Will alterative or additional treatment of treated soils with high metals be the responsibility of the contractor, the EPA, or will this be handled on an as needed basis under change order circumstances? . ANS Yes, metals testing is required during the demonstration phase only. Metals testing is for informational purposes only. The contractor is only responsible for the removal of pesticides in accordance with the Statement of Work. If unacceptable levels of metals are detected in the treated soil, the Agency will arrange for proper disposal of the treated soils. d. If treated soils require further treatment for .metals prior to disposal, what basis should be used to determine fixed cost? ANS Not applicable. • TQ74 Treated soil is to be sampled "three grab composites." Later, it states that all three must pass. Please clarify "three grab composites." · ANS Please refer to the two guidance documents for sampling and analysis referenced in paragraph 1.3(2) of the SOW.

During the Pre-Award Survey the low offerer must prove he is capable of meeting the technical requirements of the SOW. · TQBS Upon confirmation sampling of treated soil, how is clean soir disposed? If picked up by others; who performs the loading? ANS The SOW requires the contractor to deposit the treated soil on-site in an area designated by the EPA PO. (SOW section 1.3(10)). EPA is responsible for the disposition of all soil that has met the clean-up standards. TQB6 Is it. necessary that the proposed technology use a carrier gas, or can an anaerobic environment be maintained through other means? ANS If an appropriate technology can be sited that does not use a carrier gas so that less than 500 DSCFM are discharged, then there would be no recycle requirement. However, the exit gas will still have to be condensed and a 5~ limit of oxygen in .the desorption chamber must be met. See SOW paragraph 1.1(8) for excluded technologies. • TQ87 Must the contractor operate the condensing system to a temperature of minus 20 degrees Celsius or can the vendor simply operate the system such that the gas meets the appropriate discharge criteria at the point it is discharged to atmosphere? · ANS The condenser criteria has been changed to 0 degrees celsius, but the criteria to condense the exit gas remains unchanged. 20 I I I I I I I I I I I I I I I I I I I TQ88 Reference Attachment A, Section 2, 1 -1, Several of the regulations specified are not appropriate for this project and should be removed from the specification, These include: 40 CFR 264 Subpart F -Closure and Post-Closure, This is not typically an ARAR under CERCLA and contains numerous administrative. requirements that are not relevant to this project. 40 CFR 264 Subpart· G -Financial Requirements.

Is that quantity included in, or in addition to the .stated estimate . of .13, 700 cubic yards of contaminated material stored under tarp? ANS The borrow pit was local in Beaufort County, with the Agency using the same pit as source of backfill for the excavated areas as well as to anchor the tarp. The Agency sampled the soil from the pit on several occasions to confirm it had less than l ppm total pesticides. Approximately 10 to 20 cubic yards of this material was used to anchor the tarp, and within the accuracy of the survey of the pile it is included in the estimate. TQ102 ANS No. Is there a requirement to use an US EPA Contract (CLP) Lab on this project, or on any parts of this project? TQ103 Please clarify the statement that the Contractor will be required to dispose of only the soil containing bags but not any of the debris generated from treatment activities or the soil separation process on site. ANS The contractor is responsible for the disposal of t~e bags that are in the warehouse. Once emptied of soil the bags will be considered RCRA empty containers, and not hazardous waste. As for the remainder of the debris in the pile please refer to the answer to TQ91. TQ104 Please clarify the reference ( Specification 2. 1.1 - RCRA) to the requirements of 40 CFR 264, et seq. It appears that this requirement would require a Part B Filing, financial responsibility and funds the contractor to treat this material on-site. As we are not receiving Hazardous Waste• but merely treating on site under an existing Emergency/Remedial Response Action, we cannot see how this applies. Please advise if this is being referenced as a technical guidance document only, and if so, please the extent and scope and limitation. ANS Please refer to the answer to TQ88. TQ105 Please address the question concerning any specific 24 I I I I I I I I I I I I I I I I I I I limitations on the use of the site and buildings thereon, specifically work hours, adjoining tenant access, access and use of soil bag storage area and additional fencing. f ANS The current building tenant will be using his half of the building during this project. During performance, the contractor shall not restrict the entry or exit of vehicles from Campbell trucking. Entry to the work area should be accomplished by driving around the rear of the building (EPA side) so · as not to pass the front entrance of Campbell Trucking. Exit should be accomplished in the same manner. The area on the south side of the property in the vicinity of the current stockpile is all available for use (power easement excepted), as well as the western portion of the property and warehouse. There are no restrictions on work hours. No additional fencing is required by the SOW. TQ106 Are there any additional limitations on the generation or source of the heat used by the system to volatilize and destruct · the contaminants, if the requirements of no polluting off-gases and no direct firing contact, utilizing radiantly• supplied heating, but without an afterburner, fume incinerator or other thermal incineration system are otherwise met? ANS No. Restrictions on acceptable. process technologies are identified in the SOW. TQ107 Can treatment continue while the sampling of the 500 ton or yard batches are undergoing analysis if the piles are segregated? ANS Yes. TQ108 Request for Documentation ANS a. Please provide, copies of. the site topographical ( and boundary, if available) survey which were performed at the FCX Site to assist us in confirming quantities of material; See the answer to technical question 4. A survey was conducted of the pile, not the Site, but it is attached. Site diagrams in th! Attachment tc:i the SOW are the "boundary diagrams" readily available. only The only b Please provide a copy of OSWER Directive 9360.4-01, Guidance for Removal Activities, Sampling QA/QC Plan and Data Validation Procedures (April 90) EPA/540/G-90/004; ANS If you would like a copy of this document, please send a separate, written request to the address in block 7 of the 25 I I I I I I I I I I I I I I I I I I I solicitation, or you may fax your request to 404-347-2400. c. Please provide a copy of The Environmental Compliance Branch Standard Procedures and Quality Assurance Manual, 1 Feb 91 ( US EPA Region IV, Environmental Services Division); ANS If you .would like a copy of this document, please send a separate, written request to the address in block 7 of the solicitation, or you may fax your request to 404-347-2400. d. Please provide a copy of the Record of Decision (ROD) for this Site. ANS No ROD concerning the final disposition of the soil has been issued by the Agency. TQ109 Please provide a list of plan holders and a list of site walk attendees. ANS See answer to technical question 52. TQ110 Is the HDPE pile liner considered hazardous material? What about the bulk lift bags and the visqueen material in the warehouse? ANS Once free of contaminated soil the•pile liner, bulk lift bags, and other containment materials will be considered RCRA empty containers, and not hazardous material. TQlll Will the EPA sign all permit documentation, as required for local permits (eg. Erosion Control, Water Discharge, etc.)? ANS EPA will sign any local permits required. TQ112 How often will carrier gas vented to atmosphere be required for analysis to meet the CAA standard cited on page 10. Section 2.0 -Applicable Laws and Regulations? ANS Sampling a·nd analysis of gas discharges from the treatment system will be addressed in the contractor's sampling and analysis plan. The sampling and analysis plan requires the contractor to describe sampling and analysis procedures to be used during "full scale operation." TQ113 If a thermal desorber has the temperature capabilities to drive off all hydrocarbons and has a thermal oxidizer unit that can reach temperatures up to 1900 F with a six second retention time, can this unit be equipped either 26 I I I I I I I I I I I I I I I I I I I ANS No. with carbon canisters or a wet scrubber and meet the criteria set forth not as a closed system but as a viable alternative. TQ114 Please define carrier gas requiring 90% recycle (note Attachment A, Section 1.3 (9) and Section 1.3 (9)b) if a 5 to 10 cfm nitrogen purge is used to sweep the vapors and steam. ANS The steam will not be required to be recycled, especially since it will be condensed to 0 celsius and likely discharged as water. It is assumed here that the "vapors" referred to here are the materials volatilized from the soil itself, which would not be considered part of the carrier gas stream. If the resulting gas flow rate exiting the condenser is less than 500 DSCFM then no carrier gas recycle would be required (see answer to TQ24b). However, if the low flow conditions could not be met then the nitrogen sweep proposed in this scenario would require recycle, and 90% of the 5 to 10 cfm would have to be returned to the desorption chamber. Please note that the air discharge rate would be limited to 10% of the nitrogen and steam gas flow rate. TQ115 How will non-detect values be weighted in calculating the- "total pesticide concentration" of equal to or less than 1.0 mg/kg as identified in Attachment A, Section 3.2.2, and is this is on a dry or wet weight basis? ANS Non-detects are counted as zero. The calculations should be on a dry weight basis. TQ116 Will it be possible to obtain some relief from the schedule? This fast-track schedule will limit competition because it is not realistic to assume that contractors have the specific type of equipment required for this project ready and waiting· in the yard. Therefore, a more realistic time frame . for Start of Demonstration would be 60 days from the approval of the Demonstration Plan as shown in the proposed schedule. Secondly, submission of recommended operating parameters within 3 days would not give adequate time for analysis of·stack samplin~ data if sampling was delayed until the end of the demonstration period. We suggest that EPA consider increasing this time period from 3 days to 14 days. In terms of the overall impact of these time changes on the schedule, we have included a proposed project schedule for your review. We suggest that you consider increasing the total project from 510 to 600_ days. This 17. 6% increase in the project duration should not adversely affect EPA since the increase in time is 27 I I I I I I I I I I I I I I I I I I I prior to thermal treatment where EPA has oversight coats. ANS The Agency will reschedule the start of the demonstration to 45 days after the approval of the Demonstration Plan. The period to submit recommended operating parameters will be extended to seven days. The overall time for the completion of the project remains unchanged. These changes have been made to the appropriate parts of the SOW. TQ117 If the vent gas meets the CAA standards listed in Attachment A, Section 2 .1. 4., can it be recycled back to the firing chamber of the indirectly heated thermal desorber? ANS No, TQllB If steam is used as the carrier gas, and therefore fully condensed in the cooling/chiller system, can we discharge all of the remaining air resulting from air entrained in the waste and minor system leaks? ANS Air discharge rates would be limited to 10% of the steam flow rate plus any other sweep gas used, unless the total discharge of non-condensables is less than 500 DSCFM ( see answer· to TQ24b) • TQ119 Is there any treatability data available to indicate treatment parameters necessary to meet the 1. 0 mg/kg total pesticide clean-up requirement? ANS No site specific treatability work was done, however there was ample evidence in current literature to indicate that the 1.0 mg/kg treatment standard could be met. • 28 I I I I I I I I I I I I I I I I I MEMORANDUM Subject: FCX Excavation, Bagging and Backfill Summary Excavation Summary Stockpile Volume (Thru Jan. 92)* Excavation Volume (9/12/92-9/16/92) Excavation Volume (11/17/.92-11/23/92) Excavation Volume (ll/30/92-12/9/92**) TOTAL .
