Diamond, Direct Office of Waste Programs E TO: Waste Management Division Directors Regions I - X Purpose The purpose of this memorandum is to bring to your attention the second set of recommendations for streamlining measures that will reduce the cost and duration of RI/FS's. Backqround Two related projects, the RI/FS Cost Study and the attached RI/FS Improvements Phase II Streamlining Recommendations, have been completed recently. Together they address measures to achieve the national goal of an RI/FS which takes 18 months on average and typically costs no more than $750,000 per operable unit and $1.1 million per site. The Cost Study results were sent to you on October 29, 1988. Included were trends in rising RI/FS costs, contributing factors, and management tools being developed to help bring costs down. The RI/PS Improvements Phase II built on earlier work. Phase I, a management forum held last January, produced a set of immediately available streamlining measures. These were contained in an April 25, 1988 memorandum. Phase II combined the efforts of five Regional and Headquarters workgroups which focused on Procurement, Program Management, Technical Considerations, State Involvement, and Enforcement. Attached are a set of recommendations forwarded to us by the RI/FS Streamlining Steering Committee. Incluqed is an example application of the "Streamlined Approach" based on the Observational Method used in the geotechnical engineering field. We endorse the use of this approach for dealing with uncertainty in subsurface work, providing there are no site- specific enforcement concerns. ------- 2 The Cost Study and Streamlining Project results have been combined to form a joint set of recommendations. Not surprisingly, several steps we can take to cut back schedule demands also lower costs. Measures already referred to in the Cost Study, such as the use of standardized elements in RI/FS wor~ pla~s, a greater reli3~ce on i~-~oc~~ st~f~ t~ scope and .fo:us worK p:~~nl~g, and t~e lnc:eased etficiency o~fared through A~CS, ca~ save both money and ti~e. Objective Even though some of these suggested actions continue to be discussed and evaluated, others may be considered for immediate implementation. Several recommendations require further work by joint Headquarters and Regional teams, but other recommendations are for actions that you can take now. Below, we highlight a number of these. Imp lementation CONTRACTING AND PROCUREMENT o Delegating work plan approval to Regional Project Officers Once the Contract Officer has approved the work scope and overall funding for a complete project, the authority to approve workplans not affecting total costs will be delegated to Remedial Project Managers. This recommendation will be incorporated into the forthcoming ARCS Contracts Users' Manual. Regions should prepare now to institute this authority. o Granting authority for direct subcontracting to ARCS and REM Contractors Following successful completion of a Contract Procurement System Review Audit, each REM and ARCS contractor will be granted authority to directly approve subcontracts up to $250,000. HSCD/OSWER will work with PCHD/OARM to schedule audits based on contractors having the greatest national workload. o Incorporating cost evaluation criteria, cost controls, and cost standards into ARCS management The RI/FS Cost Study found that increased emphasis on cost management through cost reporting by contractors will lead to the development of cost planning criteria ------- 3 and enhanced ability to influence pricing at project planning stages. During the coming year, OPM/OERR and HSCD/OERR will work with the regions to: emphasize cost controls and reporting in ARCS performance reviews, carry ~ut work de~eloping tre~ds and rules-o~-:hurnb leading to e'/entual ccst crlter:a, and build cost control measures into RI/FS Guidance and train in.; . PROGRAM MANAGEMENT AND ENFORCEMENT o Inplernenting the "Streamlined Approach" This approach is defined by exanple in the enclosed cas~ study. Extending past practice under the bias- for-action, it encourages early identification of that part of the site where remedial action can begin quickly. It also encourages the adoption of flexible remedies which can be adjusted during design and construction based on actual site conditions encountered in the field. The underlying assumption is that complete characterization during the RI/FS is not feasible or cost effective. Therefore, the streamlined approach initiates action where the remedy is clear, the full extent of contamination can be determined while underway, and other concerns do not preclude this' approach. In the application of this approach, work on project scoping, project planning and project approvals should correspondingly be reduced in depth and detail. Regional staff should evaluate site specific circumstances, including enforcement concerns, to determine the amount of data needed to support remedy selection and implementation. Both OWPE and OERR will work closely with the Regions over the coming year in applying this approach. Regions should review their sites with planned or recent RI/FS starts for the use of this approach. o Use of RODs which include Contingency Remedies in Select Cases. Ordinarily, the Agency identifies a preferred alternative in the Proposed Plan and selects a single remedy in the ROD. Generally, a treatment class should be selected instead of a specific technology ------- 4 process option. For example, RODs should select thermal destruction, instead of specifying rotary kiln incineration and thereby provide flexibility to implement more than one thermal destruction process. It will not always be practicable to conduct sufficient testing during the RI/FS to address the uncertainties a~~:~ci~re~ wi~~ ~ t~:~~01c~'/ t~at ~Ql~s cre~~ Dr2~~5e (.=. ,- ; -,., 0 .. ~ t" ,,;::; ') - .., ,~ ~ 'J :.;;' - - &.

In these situations where additional testing during remedial design will be necessary to verify the performance of the preferred technology, a ROD may be signed that selects that technplogy but also provides a backup remedy. The ROD would contain a complete analysis of ,both remedies, and would show how the primary remedy provides the best balance, except for the uncertainty associated with that remedy, and how the backup remedy would provide the best balance if the primary remedy does not achieve its goals. In limited situations, the Agency will select a remedy from several treatment technologies which appear to be comparable with respect to the nine criteria. The comparable technology(ies) may be included in the ROD as contingency remedies, and implemented if one of them emerges as more cost-effective or practicable than the selected remedy as a result of negotiations with PRPs. In order to implement any contingency remedy, an explanation of any signific3nt difference between the remedies needs to be provided to the public. Further details on policy and procedures associated with these types of RODs will be available in the "ROD Guidance" to be completed this winter. TOOLS AND TECHNICAL SUPPORT o Standardizinq Quality Assurance pro;ect Planninq Documents With the increased availability and use of field screening methods, the need for standardized Regional QAPjP documents to speed site work planning reemerges. Regional Superfund program staff should continue working closely with their Environmental Service Division counterparts during the Remedial Investigation scoping to incorporate standard QAPjP items wherever possible. ------- 5 'A workgroup of Headquarters and Regional staff will supplement current QAPjP guidance with supporting QA materials for non-CLP analyses. One tool that was recently distributed is the Field Screening Methods Catalog. o Hcldinq Re3ionell~ spo~sored, Hea~~uarter3 s~pported tech~l:al meetln~s and ~ork5nops On a quarterly or semi-annual basis, meetings covering subjects selected by the Regions for the Regions, and including State and contractor participation, will be held to foster technology transfer, exchange of lessons learned, and elevation of problems needing national program attention. Headquarters will provide administrative and facilities Support for these meetings which will be rotated among the Regions. The first meeting is planned for the second quarter of FY89. The attached management summaries of recommended actions include other steps we can take toward our goal of having an RI/FS process that takes 18 months and costs $759,999 on average. These recommendations will be the subject of discussions at upcoming Division Director and Branch Chief meetings. In the interim, we invite your comments and suggestions.. Work to streamline the RI/FS process and reduce costs will require our focused management attention over the coming year.' These recommendations give us a good place to start. Attachment cc: J.

PHASE II STREAMLINING RECOMMENDATIONS Office of Emergency and Remedial Response Hazardous Site Control Division January 1989 ------- OSWER Directive 9355.3-06 INTRODUCTION The RI/FS improvements initiatives process began with the issuance of the July 22, 1987 OSWER Directive 9355.0-20 entitled "RI/FS Improvements". Continuing guidance was issued to the Regions in the April 25, 1988 OSWER Directive entitled "RI/FS Improvements Follow-up". Since that time work has continued regarding the development of recommendations that could help streamline the RI/FS process. Six workgroups were formed which were charged with analyzing various portions of the RI/FS process and developing solutions to identified problems. The workgroups addressed the following subjects; 1) Technical issues, 2) Procurement issues, 3) Program management issues, 4) Enforcement issues, and 5) State issues. These workgroups were composed of Regional, Headquarters, State, Federal Facility, and contractor staff. A Steering Committee composed of Regional and Headquarters management also was formed to oversee each workgroup's activities and provide a Quality Assurance (QA) function. The committee also developed additional implementation options to the issues identified by the workgroups. Attached are a number of recommendations/implementation options which are the culmination of the workgroups' and Steering Committee's activities. The recommendations are listed ~elow: Technical o Institute Regional Remedial Contractor Training o Better Utilize Pre-remedial Data During RI Scoping o Make QA Requirements Consistent and Consolidate Documents Whenever Possible Procurement o Delegate Work Plan Approval to Regional Project Officers o Grant Authority to REM/ARCS Contractors to Directly Approve Subcontracts o Establish Separate Regional Analytical Services Accounts o Develop Source Lists for Subcontractors ------- OSWER Directive 9355.3-06 Project Manaaement o Implement the Streamlined Approach. o Conduct Technical Meetings/Workshops State o Improve Training and Technology Transfer Mechanisms for RPMs o Use Generic Documents and Core of "Expert" Reviewers to Expedite Document Production and Review Enforcement o Provide Training to RPMs on RP Oversight and Interaction o Initiate New PRP Searches with SOWs Specific to Site Type . o Use RODs which Include Contingency Remedies in Select Cases . Because of their similarity, the State recommendations have been combined with recommendations of the Technical and Program Management workgroups. 2 ------- OSWER Directive 9355.3-06 A CASE STUDY THE STREAMLINED APPROACH INTRODUCTION EPA, in its search to improve the RIfFS process, is reviewing a number of possible initiatives. One effort has involved the formulation of an example of how the inherent flexibility in the traditional RIfFS process can be maxi- mized to accomplish more effective, efficient studies. This example is described as the "Streamlined Approach" in the case study that follows. The discussion highlights how the RIfFS process as it traditionally has been practiced can be modified to reach remedy selection decisions sooner and to expedite remedial action implementation. The approach also emphasizes the development of flexible remedies that can be "fine-tuned" during implementation. . The intention of this study, and discussion generated from it, is to determine the applicability of the Streamlined Approach to Superfund sites and to assess the potential of . this method to improve the quality, schedule and/or cost of the RI/FS process. While this particular example represents a specific approach that is still conceptual in nature, it should be noted that this technique is fully consistent with the framework established in the revised "Guidance for Con- ducting Remedial Investigations and Feasibility Studies under CERCLA" (Draft March 1988) and the forthcoming National Con- tingency Plan proposal. This particular approach to stream- lining is beginning to be piloted informally in some Regions and States. STREAMLINED APPROACH When looking at the remedial process as a whole it has become apparent that the process has become "bottlenecked" by the uncertainties associated with fully understanding the nature of hazardous waste problems. Many of us have mistakenly assumed that the hazardous waste engineering practice can be conducted just like conventional engineering. That is, we have assumed that uncertainties are effectively reduced to manageable levels during the RI/FS phase, thereby allowing the design and implementation phases to proceed routinely. This has not been proven to be the case for many sites as new information discovered during design and implementation has forced significant alterations in planned remedies. This example of a streamlined approach paral~els a method which was developed by the geotechnical engineering disci- pline about 40 years ago to deal with the uncertainty of the 1 ------- OSWER Directive 9355.3-Qt subsurface environment.l It reflects a recognition that no reasonable amount of subsurface exploration can resolve all uncertainty and that remedial actions developed as part of the method must accommodate surprises or "deviations" from the original hypothesis. Traditionally, uncertainties have inspired intensive and lengthy efforts to find the sources of contamination and to definitively characterize sites. The streamlined approach recognizes that removal of all uncertainties is usually not feasible and focuses instead on only collecting sufficient data to generally characterize a site and support remedy selection. The resulting remedies are flexible and incor- porate specific contingencies to respond to new information discovered during remedial action. The case study which follows will propose an approach to recognize and address this uncertainty while proceeding toward the ultimate goal of site clean-up. It is important to note that this approach may not be appropriate for all problems at all sites. CASE STUDY This case study presents how the Superfund remedial process would be conducted in a streamlined manner at the hypotheti- cal Otis Recycling Superfund site. The case study is organ- ized into the following sections: o o o o o o o Background Scoping Phase I remedial investigation Feasibility study Record of decision Remedial design Remedial action BACKGROUND The Otis Recycling site is about 1.5 miles northwest of the town of Goddard and 0.5 miles north of the Hilton Hills Ipeck, R.

The Goddard County Airport is 0.5 miles northwest of the site, and land use in the vicin- ity of the site is agricultural. The eastern boundary of the site abuts Otis Ditch, which flows southeast and joins Matuka Creek 0.2 miles south of the site. Matuka Creek dis- charges into Wooly Run which in turn discharges to the Wulff River, as shown in Figure 2. The site is located on 10 acres and contains a drum storage area, a drum crushing pad, a distilling house, and a loading dock, as shown in Figure 3. Drums were removed from the stor- age area by the emergency response cleanup services (ERCS) contractor. The site was operated as a solvent distillation facility and a waste oil recycling facility from 1967 to 1982. Historical aerial photographs of the site suggested that a large number of drums was stored at the storage area throughout the entire history of the site. The photos also showed that some soil had been discolored because of spills. The geology at the site consists of 80 feet of unconsoli- dated glacial sediments overlying shale bedrock. The over- burden is divided into an upper and lower aquifer by a discontinuous, semi-confining silty clay layer. The shallow aquifer consists of 20 to 40 feet of sandy outwash while the deeper, or lower, aquifer consists of 10 to 30 feet of sand and gravel. The top of the water table is 6 to 8 feet below ground surface, and flow is generally to the southeast. However, the direction of flow appears to change seasonally, and the variability of the direction of flow was not deter- mined. The shale bedrock is of very low permeability and was not considered an aquifer. Soil at the site consists primarily of sandy glacial tills. The average yearly rain- fall at the site is 35 inches. Private water wells at the Hilton Hills Subdivision were screened in both the upper and lower aquifers. The toWn of Goddard used the lower aquifer as well as surface water from the Wulff River for its drinking water supply. Welis in the subdivision were not contaminated, and residences were not on an alternate water supply system. Groundwater sampled during the field investigation team (FIT) study was found to be contaminated with volatile organic compounds (VOCs), with one well containing a total VOC concentration of 1,100 ppb. Soil at the site was found to be contaminated with VOCs and polycyclic aromatic hydro- carbons (PAHs). Concentrations of total VOCs in the soil were as high as 10,000 ppb, and total PAHs were as high as 30,000 ppb. The FIT sampling appeared to delineate the VOC contamination in some detail. 3 ------- OSWER.Directive 9355.3-( Goddard Cctunty Alrpon OilS \l Recycling Y Corporation . .

In this case, limited field investigations and treatability studies were determined to be unnecessary and were not performed during scoping. . Highlights of some scoping activities that were completed are discussed in the following sections. Review of Existing Data During scoping the following existing data were reviewed and summarized: o. FIT report o u.s. Geological Survey (USGS) and state publica- tions o Soil Conservation Service (SCS) soil survey o Topographic maps o State files o Residential and municipal well logs o Historic aerial photographs o Log of site visit Site Conceptual Model On the basis of the existing data, a site conceptual model was developed, which is as follows: The soil is contaminat- ed with VOCs and PAHs, which occur throughout the site. The highest concentrations of chemicals are expected in the vicin- ity of the distilling house and in the former drum storage area. However, the site is much larger than these two areas, and past site activities beyond these areas are unknown. The possibility of very high concentrations (hotspots) of VOCs and other contaminants is high in both the lateral and vertical directions. In some areas, VOC contamination extends beyond the unsaturated zone to the water table. Thus, the shallow aquifer is contaminated with VOCs. An initial hypothesis is developed that identifies soil vapor extraction as a promising alternative. This hypothesis is developed after evaluation of the existing data (which indi- cates VOCs in soils may be limited in extent of contamina- tion) and also relying on previous program experience. A hypothesis is also developed :or the groundwater scenario. This hypothesis calls for a pump and treat system as a 5 ------- 05WER Directive 9355.3-06 promising alternative. A hypothesis is not able to be devel- oped, at this time, for the non-volatile soils contamination due to a lack of sufficient data. General Response Actions Using the existing site information and the site conceptual model, general response actions were evaluated. This was done to ensure that potential location-specific and action- specific ARARs would be identified and that the data needed to select a remedial alternative would be collected. The alternatives that could potentially be implemented at the site were considered for development, and are listed below for soil and ground water: o 50il No action (natural attenuation) In situ treatment (e.g. soil vapor extraction, biological treatment, soil washing) Containment (e.g. grout walls/curtains, cap- ping) Removal and onsite treatment (e.g. inciner- ation, composting) Removal and offsite treatment (e.g. incinera- tion) Removal and offsite disposal in a RCRA land- fill Combination of containment and removal o Ground water No action (natural attenuation) Extraction and treatment (e.g., pumping with air stripping Physical and hydraulic containment of the shallow aquifer; not applicable to the deep 'aquifer if it is also contaminated In situ treatment was excluded for ground water because the technology is not applicable to the wide variety and concen- trations of contaminants found at the site. 6 ------- Data Needs OSWER Directive 9355.3-0( Data needs identified at the site during scoping are as fol- lows: o Site geolo~y and stratigraphy Site hydrogeology including aquifer and confining layer properties, hydraulic conductivity, horizon- tal continuity of the confining layer, flow direc- tions and vertical and horizontal gradients, ground-water velocities, and recharge/discharge relations o o Nature and extent of ground-water contamination o Nature and extent of soil contamination o Nature and extent of surface-water and sediment contamination PHASE I REMEDIAL INVESTIGATION This section describes the objectives of the actual Phase I RI. The field activities and the conclusions of the Phase I RI are also described. Objectives of the RI The objectives of the Phase I RI are presented below: o Characterize the horizontal and vertical extent of soil contamination throu~hout the entire site, focusing in particular on the drum storage area and the distilling house . o Characterize the horizontal and vertical extent of groundwater con~amination throughout the entire site o Gather enough information to complete the Feasibil- ity Study (FS) o Help prove or disprove the initial hypotheses and assist in the selection of the preferred alterna- tive These sampling programs are designed to gather sufficient data to determine the qeneral extent and nature of contami- nation. The objectives are not designed to "fully charac- terize" the site, as has been done traditionally. ------- OSWER Directive 9355.3-0l Field Activities To accomplish the objectives outline above, the following field activities were completed for soil, surface water and sediment, and groundwater: o Soil Approximately 30 soil borings were drilled to the top of the water table at and around the drum storage area, distilling house, and load- ing dock. Samples were taken from various depths and analyzed using standard contract laboratory program (CLP) protocols for stan- dard routine analytical services (RAS) chemi- cals. A shallow soil sampling program was conducted throughout the remaining portion of the site (a total of 10 acres) using a grid pattern. Fifty samples were analyzed for VOCs using portable screening equipment. Samples that exceeded screening criteria were submitted for laboratory analysis along with about ten percent of the samples with negative screen- ing results. Five soil samples were submitted for geotech- nical analysis (i.e. moisture content, den- sity, grain size, Atterberg limits). Up to ten background subsurface and surface soil samples were collected from off-site areas and remote areas of the site for analy- sis of chemical constituents. A soil gas analysis program was conducted to investigate for VOC hotspots. o Surface water and sediment Four surface-water samples were from both Otis Ditch and Matuka were analyzed for RAS chemicals protocols. collected Creek: they using CLP Four sediment samples were collected from Otis Ditch: one was upgradient and three were downgradient of known source areas (i.e. 'the drum storage areas, the drum crushing pad, and the distilling house). Also, one upgra- dient and three downgradient samples were 8 ------- OSWER Directive 9355.3-0t collected from Matuka Creek. They were also analyzed for RAS chemicals using CLP proto- cols. o Groundwater A soil gas analysis program was conducted to determine monitoring well locations. A geophysical survey (electrical resistivity) study was conducted to define the depth to the clay layer and determine the lateral extent and continuity of the clay layer. Four well nests were installed with one well screened in the upper portion of the shallow aquifer, one in the lower portion of the shal- low aquifer, and one in the deep aquifer. Six well nests were installed with one well screened in the upper portion of the shallow aquifer and one in the lower portion of the shallow aquifer. Slug tests were conducted in each well to determine the hydraulic conductivity of the upper and lower aquifer. , Staff gauges were installed in Matuka Creek, and Wooly Run to discharge conditions. Otis Ditch, assess recharge- Water level measurements were obtained from all of the wells. All monitoring and selected residential wells were sampled using CLP protocols for standard RAS chemicals, and selected samples were ana- lyzed for BOD, COD, total suspended solids, oil and grease, and alkalinity, as well. Conclusions From The Phase I RI The understanding of the regional geology was confirmed by the Phase I RI activities. The ground-water flow direction was found to be to the southeast in both aquifers. The shal- low aquifer appears to discharge to Wooly Run except during dry periods when it probably discharges to the Wulff River, while Otis Creek and Mantuka Creek appear to be ground-water recharge sources. 9 ------- OSWER Directive 9355.3-0t The' two aquifers may be directly hydraulically connected if the silty clay layer does not exist: otherwise, there is an indirect connection such that the vertical gradient is gener- ally downward. The flow rate from the upper to the lower aquifer is estimated to be about 10 feet per year. The hori- zontal flow rate in the shallow aquifer is estimated to be' about 110 feet per year, while in the deep aquifer it is 200 feet per year. The results of the Phase I RI soil sampling program were as follows: o VOCs and PAHs were detected at a maximum depth of 6 feet below the surface in and near the drum stor- age area and near the distilling house. Concentra- tions were at or above health based levels. o Significant levels of lead were found throughout the site at various depths. o High concentrations of VOCs were unexpectedly detected in soil borings to the extreme north of. the known drum storage area. o Low levels of pesticides were found throughout the site at concentrations below health-based levels. o The results of the soil-gas program were viewed as unreliable for assessing the distribution of on-site soil contamination because they reflected the distri- bution of groundwater contamination. . The results of the Phase I RI surface-water and sediment sampling program were that no contaminants wer.e detected in either the surface-water samples or the sediment samples. Therefore, no further sampling, in these media, will take place. The results of the Phase I RI groundwater sampling program were as follows: o VOCs contaminated the shallow aquifer (above health based levels). o Contaminants were detected in all the wells that were furthest east; therefore, the eastern bound- ary of the plume was not defined. o Low levels of VOCs were detected in the deep well immediately downgradient of the distilling house. 10 ------- OSWER Directive 9355.3-0t A risk analysis was performed that showed that the contained soil and ground-water contaminatio~ that risk to the public's health and welfare and to the environment. site posed a Determine Need for Additional Data This is the point of greatest divergence with the stream- lined approach. Traditionally, we have asked "have we fully characterized the site yet?" Getting a "no" answer we plan a phase II RI to fill in the data gaps. Additional data would be collected-for soil-VOCs and groundwater. Note that we actually only fill in the data gaps until we are "comfortable" with our site understanding--we neve~ really can fully characterize the site. There- fore, some of the mindset differences with the stream- lined approach is where the "comfort" zone is reached-- "how much is enough?" The streamlined approach evaluates the phase I data to deter~ mine if the initial hypotheses have been tested to the point - where action can be taken. In this case, it was concluded. that action could be taken on two elements which are (1) the shallow aquifer, and (2) soil volatiles. These elements are combined into one operable unit. For the shallow aquifer, it was determined that extraction and treatment would be consistent with the likely long-term remedy and would not create a condition worse than the pres- ent. For the soil-VOCs, it was determined that, high concen- trations of soil volatiles should be removed under any soils remedial action because leaving mobile volatiles under a cap should be minimized as should exposing workers and the public to volatiles during excavation. Previous program experience also indicated that these alternatives would be viable options. Dealing with the non-volatile soils was less straight for- ward. An economic analysis (done at this stage under the Streamlined Approach) showed that to cap the entire site would conservatively cost about $5 million and to incinerate just the two acres of probable PAH contamination would cost at least $15 million (not including $2 to $4 million to cap the remainder). However, it was concluded, based on the selection of remedy criteria, that more evaluation (Phase II RI) and comment would be required to reach a decision. Addi- tionally, data collected during the SVE (which must be com- pleted first anyway) and the groundwater extraction remedy would aid in the decision-making process. It was also - determined that additional data collection activities would be required regarci~g the deep aquifer. 11 ------- OSWER Directive 9355.3-0( The data evaluation procedure also leads to the development of a number of reasonable deviations. These deviations are addressed during the RI/FS and monitored for during the imple- mentation of the remedy. Development of Reasonable Deviations The most probable conditions have already been discussed (Site Conceptual Model). The most reasonable deviations to the site conditions are presented below for soil and ground-water: o Soil VOC contamination could extend beyond currently known areas of contamination. Only 50 samples were analyzed for VOCs beyond the main source areas, and use of other areas of the site for hazardous materials handling, storage, or disposal has not been ruled out. VOCs hot- spots that have not been identified could be present in the soil since only a limited num- ber of samples were taken. The composition of the soil could vary. This would affect the effectiveness of several of the general response actions, such as soil vapor extraction. Soil vapor extraction will vary in effective- ness based on the volatility of the compounds. Because the site had been a recycling facil- ity, there could be contaminants other than PAHs and VOCs on site that were not detected at the sampling locations. o Groundwater The lower aquifer could contain hotspots that have not been identified. Concentrations of pesticides could be present in the shallow aquifer. The VOC contaminant plume could extend beyond the area indicated by the results of the Phase I RI sampling. Characteristics of the upper aquifer could vary substantially. This would affect jroundwater extraction effectiveness. 12 ------- OSWER Directive 9355.3-06 FEASIBILITY STUDY FOR SHALLOW GROUNDWATER AND SOIL VOCS Upon completion of Phase I it was determined that the nature and extent of the contamination had been adequately defined. Applicable general response actions and technologies address- ing the contamination were then identified. The remedial alternatives that were developed for soil and groundwater are listed below: o Soil VOCs No action Soil vapor extraction in the drum storage area and the distilling house Removal and incineration of soil o Groundwater No action Installation of an extraction well system in the shallow aquifer and treatment of extracted groundwater with air stripping Continued monitoring of both the shallow and the. deep aquifers Each alternative or combination of alternatives was analyzed against the nine criteria. This information was then used to compare the alternatives and support the subsequent analy- sis made in the remedy selection process. RECORD OF DECISION For the VOC contamination in soil, soil vapor extraction (SVE) with vapor extraction wells extending to the water table in conjunction with continued monitoring is the selec- ted remedy because SVE is lower in risk and cost than leav- ing the VOCs under a cap or excavating and treating them. Remedial action to remove VOCs from soil is initiated before selecting the remedy for soil contaminated with lead and PAHs. While VOCs removal was being undertaken, sampling is conducted to help determine the remedial action for the soil contaminated with lead and PAHs. The ROD for the removal of VOC contamination from soil would be flexible to allow for the ad~ition or modification of the remedial action (RA). The ROD therefore would include a discussion of the deviations and would address the contingen- cies to be implemented if any of the deviations were encoun- tered. These deviations would have included the following: 13 ------- OSWER Directive 9355.3-06 o If the composition or concentration of the VOC contamination is different than expected, the time frame for operating the SVE system would be modi- fied. If the time frame for operating the system becomes too long, the site will be covered with 6 inches of clean sand and gravel to minimize expo- sure while continuing the SVE system. o If the extent of soil contamination is greater than expected, or if the composition of the soil causes the SVE system to be less effective than expected, more SVE wells will be constructed. For shallow groundwater, extraction, and air stripping treat- ment along with continued monitoring is the selected remedy. This remedy was chosen because it will address the know VOC contamination. The remedy is also flexible enough to address the reasonable deviations without major changes to the sys- tem. The ROD would discuss the following reasonable devia- tions and proposed alternatives: o If the shallow contaminant plume extends farther than expected, extraction wells will be added or pumping rates will be increased. o If VOC concentrations are if the composition of the to be less effective than will be operated longer. higher than expected, or soil causes the system expected, the system o If pesticides are detected at high concentrations in the upper aquifer, the treatment system will be modified to remove pesticides from the water. o If the lower aquifer is more heavily contaminated than expected, additional extraction wells will be installed in the lower aquifer. o If contamination is detected in monitoring wells (i.e., if contaminants are not being captured by the extraction system), additional wells will be . added to the system. REMEDIAL DESIGN Pre-design requires a pump test to determine shallow aquifer properties under stress. The remaining elements of the RD are: o Design of the soil vapor and the groundwater extrac- tion systems. 14 ------- OSWER Directive 9355.3-06 REMEDIAL ACTION The SVE system and the groundwater extraction and treatment system begin operation. As part of the on-going monitoring program, pesticides are detected in the groundwater extrac- tion wells. The lead agency is prepared for this situation under this approach because this "reasonable deviation" has been addressed ahead of time and the RPM is much more pre- pared to respond to it in a technically sound and timely manner. The monitoring which takes place during the implementation of the remedial action takes on a very important role in the overall clean-up process. The RPM is not only reviewing these monitoring data to ensure that the remedial action is operating properly, but is also looking for indications of the presence of any of the reasonable deviations.

However, in certain instances, it may be advantageous to include in the ROD additional provisional remedies which could be implemented in lieu of the selected remedy. DISCUSSION: In situations where additional testing during remedial design will be necessary to verify the performance of the lead and support agencies' preferred technology, a ROD that selects that technology but also provides a backup remedy may be signed. The ROD should contain a complete analysis of both remedies and would show how the primary remedy provides the best balance across the nine criteria, except for the uncertainty associated with that remedy, and how the backup remedy would provide the best balance if the primary remedy does not achieve its goal. The ROD should describe the criteria used to resolve the uncertainty associated with the primary remedy. The revised ROD guidance will provide additional guidance in this area. In selected situations, the Agency will select a remedy from several treatment technologies which appear to be comparable with respect to the nine criteria. The comparable technology(ies) may be included in the ROD as provisional remedies, and 19 ------- IMPLEMENTATION PLAN: HQ CONTACT: OSWER Directive 9355.3-06 implemented if one of them emerges as more cost-effective or practicable than the selected remedy as a result of negotiations with PRPs. In order to implement any provisional remedy, an explanation of significant differences must be provided to the public. Headquarters will develop guidance on policy and procedures associated with these types of RODs. This information will be available in the "ROD Guidance" to be completed this winter. Linda Boornazian (FTS) 382-4836 Darsi Foss (FTS) 475-9843 20 ------- RECOMMENDATION: BACKGROUND: DISCUSSION: IMPLEMENTATION PLAN: CONTACT: OSWER Directive 9355.3-0 ENFORCEMENT Provide Training to RPMs on RP Oversight and Interaction The number of RI/FSs which are performed by responsible parties has increased and is expected to continue to increase. Accordingly, a larger number of enforcement actions as well as increased attention to oversight are expected to be necessary. RPMs are experienced in daily interactions withPRPs, but would benefit from inter-regional training addressing common issues. Further, there is relatively little experience with enforcement of some AOU or AOC provisions directed at improving the timing and quality of RP work, for example, stipulated penalties. Standard language has been developed in the context of the Settlement I/D Workgroup for specific AOU/AOC provisions. Training on uniform enforcement of existing agreements and uniform language for new agreements will improve RI/FS quality. Training on daily interactions, cross-regionally, will also improve quality and programmatic consistency. OWPE training staff should design a course for implementing this training. Debby Thomas (FTS) 475-7028 17 ------- RECOMMENDATION: BACKGROUND: DISCUSSION: IMPLEMENTATION PLAN: HQ CONTACT: OSWER Directive 9355.3-Q( ENFORCEMENT Initiate New PRP Searches with SOWs Specific to Site Type Often a single individual is responsible for initiating searches for these sites, which are seldom assigned to a RPM at this stage. A single generic SOW is not appropriate for a range of site types. Region I has had success with the recommended approach. Site-specific changes necessary to modify these scopes are minimal, making a workload of up to 30 searches more manageable. The enforcement policy branch, in OWPE, is encouraged to develop scopes of work for initiating PRP searches which are specific to site type using the Region I experience as a basis. After Regional review and comment, the model language should be distributed to the Regions. Steve Suprin (FTS) 475-8254 IS ------- OSWER Directive 9355.3-0( PROGRAM ~AGEMENT RECOMMENDATION: Conduct Technical Meetings/Workshops BACKGROUND: Due to the ever evolving nature of the hazardous waste field, technologies and policies are constantly changing. Many RPMs have the responsibility of managing highly technical and policy sensitive projects while having little or no previous experience. It is therefore very important to continually provide opportunities for junior RPMs and more experienced project managers to meet and learn from each other's experiences. DISCUSSION: These meetings should be topic specific as well as provide the latest policy regarding the specific subject. Topic specific briefing papers should be prepared as a product of these meetings and distributed to the Regions. Sample topics could include wood preserving sites, battery recycling sites and municipal landfill sites. . Following are issues which may be considered in the context of each topic: 1) Technical skills, and 2) Guidance updates. However, a variety of topics should be made available. In addition, meetings will have a session on interpersonal skills. IMPLEMENTATION PLAN: OERR will coordinate with the Regions to help organize these meetings. The regional programs (Division Director) will be asked to provide topics, suggested times and locations, and technical and logistical support for the meetings on a rotating basis. The first meeting is tentatively planned 15 ------- OSWER Directive 9355.3-06 for 2nd quarter FY 89. RPMs and others will be asked to present topic specific papers at these meetings. This will facilitate the exchange of ideas and experience among Regions. Management is also encouraged to ensure that sufficient funds are allocated for these meetings and workshops. Managers should keep abreast of the training needs of staff as well as the training opportunities available to them. their State representatives and contractors staff should also be encouraged to attend and participate in these meetings. . HQ CONTACT: Randy Kaltreider FTS 382-4491 16 ------- RECOMMENDATION: BACKGROUND: DISCUSSIO~: IMPLEMENTATION PLAN: HQ CONTACT: OSWER Directive 9355.3-06 PROCUREMENT Develop Source Lists for Subcontractors Considerable time delays have been encountered during the subcontractor procurement process. Pre-qualified lists of subcontractors must be developed by the prime contractor as part of this process. This has proven to be a long and tedious procedure. The use of a pre-qualified list of drilling subcontractors during the REM IV contract has helped reduce the time required to procure these services. Source lists could be developed and maintained by the Regional offices and used by the ARCS contractors within each Region. These source lists would be available to aid them in developing their specific pre-qualified lists of subcontractors (i.e. drilling, treatability studies, surveying, et c . ) . The Regional offices, with Headquarters assistance, should compile a list of subcontractors that have been used by the REM contractors in the Region. This list should then be made available to all ARCS contractors for possible services. The REM contractors should be contacted and asked to generate this list. Randy Kaltreider (FTS) 382-4491 ------- RECOMMENDATION: BACKGROUND: DIsceSSION: IMPLEMENTATION PLAN: HQ CONTACT: OSWER Directive 9355.3-06 PROGRAM MANAGEMENT Implement the Streamlined Approach The Streamlined Approach (see accompanying case study) is an approach to the remedial process which implements the NCP's goal of a bias for action. It explicitly recognizes and addresses the uncertainties encountered during hazardous waste site remediation. This approach requires the RPM to closely evaluate existing data and determine the earliest point in time that work can begin at the site (bias for action). The approach encourages earlier remedy selection and remedial action. It also emphasizes the development of flexible remedies that can accommodate changes encountered in the field. The case study will be given to the Regions to highlight the Streamlined Approach. Each Region should look at implementing this approach during FY89. HQ will provide the Regional Offices with support during the planning and implementation phases of these studies in FY89. Regional staff should evaluate site specific circumstances, including enforcement concerns, to determine the amount of data needed to support remedy selection and the ability to implement the remedy.

HQ CONTACT: Randy Kaltreider (FTS) 382-4491 ------- RECOMMENDATION: BACKGROUND: DISCUSSION: IMPLEMENTATION PL&~: HQ CONTACT: OSWER .Direc.ti ve 9355.3-06 PROCUREMENT Establish Separate Keglonal Analytical Services Accounts Concern has arisen that since CLP services are "free" to the Regions, RPMs will under-utilize other available analytical services rather than budget them in individual RIfFS projects. Separate Regional analytical services accounts should be established to fund certain CLP levels, with the remaining funding to be used by the Region at their discretion (i.e. local labs, mobile labs, contractor labs, CLP labs, etc.). This would ensure adequate CLP utilization while providing the RPM with a range of financially "equal" analytical alternatives to choose from. Regional ability to track the CLP budget will not solve this problem. Representatives of OERR and Contracts are continuing to meet to work out the funding and contractual changes that must be made to the system in order to put this recommendation into place. The SCAP would also have to include this budget item. This issue will be resolved by the 3rd quarter of FY 89 so the Regions can plan for it in their FY 90 budgets. Randy Kaltreider (FTS) 382-4491 ------- RECOMMENDATION: BACKGROUND: DISCUSSION: IMPLEMENTATION PLAN: HQ CONTACT: OSWER Directive 9355.3-06 PROCUREMENT Delegate Work Plan Approval to Regional Project Officers (RPOs) Substantial time is lost during the work plan approval process when documents must be sent to HQ to be approved by the Contracting Officer (CO). Re~ional authority would eliminate the time required to obtain CO approval. Work plan approval, not involving additional funding, should be delegated to the RPOs. The Federal Acquisition Regulations (FAR) do not require that the CO approve these types of requests. It should, therefore, be a relatively simple process to incorporate this suggestion in the existing SOPs. OERR is presently working with PCMD to finalize the details regarding the implementation of this recommendation, which will be incorporated into the forthcoming ARCS Contracts Users' Manual. Randy Kaltreider (FTS) 382-4491 9 ------- RECOMMENDATION: BACKGROUND: DISCUSS:ON: !MFLE~EN:A::8N ?L~\: OSWER Directive 9355.3-0~ PROCUREMENT Grant Authority to REM/ARCS Contractors to Directly Approve Subcontracts The process of subcontractor approval is taking too long and is delaying remedial activities. The number of contract document handoffs must be reduced as much as possible. REM/ARCS contractors should be given the 'authority to directly approve subcontracts up to $250,000. The $250K figure represents 90% of the subcontracts awarded by REM II, REM III, and REM IV. Fcllowing ~he successful completion of a Contract Procurement System Review (CPSR) audit, the REM/ARCS contractor will be granted the authority to directly approve subcontracts up to S250K. This approval will be for any EPA Superfund contract that is operated out of the office and follows the same financial policies and procedures. OERR will work with PCMD to set a priority for scheduling these audits. The ARCS contractors with the greatest national work load will be the first to have audits performed of their procurement systems. This list will be developed in the first quarter of FY 89 and the reviews will follow. Regions are encouraged, through the contract:=- performance evaluation process, to hold REM/ARCS contractors acc~untable for having acceptable procurement systems in place in order ------- RECOMMENDATION: BACKGROUND: DISCUSSION: IMPLEMENTATION PLAN: OSWER Directive 9355.3-06 TECHNICAL Make QA Requirements Consistent and Consolidate Documents Whenever Feasible Historically, Headquarters and the Regions have tended to view QA requirements separate from the remainder of the data collection process. This has led to some miscommunications between the Superfund program and ESDs. When QA is not considered early in the RI scoping process, delays in QAPjP preparation and errors in field work can result. . A concern has .also arisen regarding the non-uniformity of QA requirements' among the Regions. Other Federal Agencies, the contracting community and responsible parties have found that QA requirements are not at all consistent from Region to Region. Although this is partly a Regional responsibility, in several cases, Headquarters guidance has been contradictory in its treatment of QA. The process of standardizing QAPPs, field screening methods, and QA requirements for non-CLP labs will lead to ease in the consolidation of these items into SAPs and Work Plans. For example, Region III has begun a similar initiative and has found that standard items can now easily be incorporated into planning documents (such as the SAP) by reference. This has ~een shown to save time during document preparation and review. Regional Superfund programs should continue to work closely with their ESDs during the entire remedial process. Special attention should be given to assure that ESDs are involved in the RI scoping process, especially in designing a sampling program to achieve DQOs, once an RPM has determined them. ------- OSWER Directive 9355.3-06 The Regions should be made aware that the Field Screening Methods Catalog, presently being prepared by OERR, will be available shortly. It contains descriptions of approximately 31 methods currently being used in the Regions. Regional and Headquarters staff should also consider convening a workgroup which would further tailor the current QAPP guidance to the Superfund program. HQ CONTACT: Lisa Carson (FTS) 475-9758 c ------- OSWER Directive 9355.3-06 TECHNICAL RECOMMENDATION: Better Utilize Expanded Pre-remedial Data During RI Scoping '- BACKGROUND: Only a limited ,amount of data collected by the FIT have been useful in the RI scoping process. In some cases, the SI data were too old and generic in nature and therefore not very useful during RI scoping. At other times, due to poor communication, the remedial program has no: obtained potentially useful pre-remedial data. DISC~SS!ON: The pre-remedial program has developed the guidance for the Expanded Site Investigation (ESI). They would like input from the remedial program regarding the types of additional data that could be gathered during an ESI whic~ would also be useful during RI scoping. The pre-remedial program will be updating this guidance even further when the revised Hazard Ranking System (HRS) is final. [The term ESI will be replaced by Listing Site Inspection (LSI) in FY 89.] The following data could be collected during an ESI and would be useful during RI scoping: o Utility survey o Meteorological survey o Physical properties of test cores The following have also been identified as potentially useful and are already par: 0: the ESI. o Geophysics o Surveying and mapping ------- :M?LEMEN7AT!O~ ?L~~: HQ CONTACT: OSWER Directive 9355.3-06 o Aerial photos o Existing well inventory o Health & Safety Plan prep. o Chemicals of concern During all of the above mentioned activities, non-time critical information will be collected which the workgroup feels will be helpful during RI scoping. However, where necessary, these data should be updated routinely; prior to scoping and during work plan preparation to aid in scoping and to be more time efficient. The remedial and pre-remedial programs are encouraged to interact prior, during, and after the commencement of the ES1/LS1 to encourage the collection of data that will benefit both programs. In most cases, data ~equired by the pre-remedial program may prove useful in RI scoping. Discussions with pre-remedial staff in each Region may point out areas where the p~e-~emedial data may satisfy remedial program needs. The RPMs should determine the need to update the existing information during the scoping process. The pre-remedial workgroup can be used as a forum to increase communication between pre-remedial and remedial staff and as a resource to ensure that remedial data needs are addressed as much as possible in the future. Lisa Carson (FTS) 475-9758 ------- RECOMMENDATIONS: BACKGROUND: DISCUSSION: IMPLEMENTATION PLk~: OSWER Directive 9355.3-06 TECHNICAL Institute Regional Remedial Contractor Training Regions III & IX have found that investing time upfront to educate its REM/ARCS contractors about the Regions' expectations for RI/FSs makes for a smoother RI/FS process. Resources will be required upfront, however, the Region's investment will ensure that all parties involved begin on a solid, common foundation. Regions III and IX have concentrated on training which teaches the contractors the "how tos" of dealing with their individual Regions. ESD's contribution to the training is especially helpful in clarifying QA requirements. A list of possible training topics is found below. o Data validation o Regional review process o Sample scheduling o Mechanics of sample submission o Use of ESATs and other Regional contracts o DQOs OERR will keep Regions abreast of other Regional training activities. However, Regions are encouraged to communicate with eac'h other regarding contractor training. It is also important to invite State participation in this activity. OE~~ recognizes that there is Regional variation regarding these training topics. Therefore, the Region III & ------- OSHER Directive 9355~3-06 IX training materials could be used as guidelines and supplemented as necessary. HQ CONTACT: Lisa Carson FTS 475-9758 ------- |
