February 25, 1999 EPA-SAB-EEC-LTR-99-002 Honorable Carol M. Browner Administrator U.S. Environmental Protection Agency 401 M Street, SW Washington, DC 20460 Subject: Science Advisory Board Review of the Implementation of the Agency-Wide Quality System Dear Ms. Browner: In response to a request from the National Center for Environmental Research and Quality Assurance (NCERQA) of EPA's Office of Research and Development, the Quality Management Subcommittee of the Science Advisory Board's (SAB) Environmental Engineering Committee (EEC) reviewed the implementation of the Agency-wide Quality System (QS). The Subcommittee met in Washington, DC on September 22-24, 1998. In the Charge for this meeting, the EEC Quality Management Subcommittee was asked to use available information to evaluate the Agency's success in implementing the Agency-wide Quality System. The Subcommittee restricted its review of implementation to data collection because the Agency's Quality System presently does not address other activities, such as modeling or environmental technology. At an earlier meeting, the Subcommittee addressed the relevance, completeness and practicality of the Agency's Quality System in a letter report (EPA-SAB-EEC-LTR-98-003). The focus of the Agency's Quality System on data collection, rather than other activities, was documented as an issue of concern in the previously cited SAB report (The complete Charge for both meetings is provided in Enclosure A, and Enclosure B contains a summary of the findings detailed in the previous report). The Subcommittee commends the Agency for developing its Quality Program and recognizes the Quality Assurance Division (QAD) for its precedent-setting work. The Subcommittee also credits the QAD for its efforts to implement the Quality System, including: a) the generation of widely-accepted policy and project-level guidance and requirements; b) a training program that has introduced the Quality System concepts to many Agency personnel; c) a review and approval process for Quality Management Plans (QMPs) that has guided implementation of the Agency's Quality System; d) the use of management system reviews (MSRs) to identify areas of needed improvement and success stories for Quality System implementation; and e) the use of Quality Assurance Annual Reports and Work Plans (QAARWP) to document past and planned efforts to implement the Quality System. The Subcommittee wishes to draw the following overarching findings to your attention: a) Implementation of the Quality System is uneven within the Agency, increasing the likelihood of problems with data quality and the associated decisions. b) The majority of states that have primacy for implementing numerous environmental programs are generating data of unknown quality because they lack approved Quality Management Plans (QMP). c) A well-implemented Quality System is necessary to accurately measure progress under the Government Performance Review Act (GPRA). d) Incomplete implementation of the Agency's Quality System precludes proper evaluation of internal and external activities; this results in potential for waste, fraud and abuse. e) The present reporting status of the Quality System function within the Agency organization lowers the profile of the Quality System and denies access to the proper level of authority and the independence necessary to oversee the quality of the Agency's services and products. f) Senior Management needs to be a champion for successful implementation of the Agency's Quality System or acceptance and implementation of the Quality System will remain uneven and incomplete. These findings are discussed in more detail below (in addition, findings and recommendations specific to Quality System Organizational and Program components will be found in Enclosure C; Enclosure D addresses Project level components). a) Implementation
of the Quality System is uneven across the Agency: After
reviewing program and regional Quality Management Plans (QMP),
management system review (MSR) reports, reviews, surveys, and
conducting interviews, the Subcommittee concluded that implementation
of the Agency's Quality System varies across the Agency, within
regions and programs, and among states and grantees. Because the QMP is the blueprint for implementing an organization's Quality System, the QMP is an indicator of the importance an organization assigns to the Quality System. Timely, coherent, and approved QMPs are reassuring. Organizations that lack a QMP, that are tardy in preparing the QMP, that operate for extended periods without an approved QMP, or that suffer from internal inconsistencies between QMPs at different levels are worrisome. Such behaviors imply that compliance with the Agency's Quality System is unimportant to the organization. The Subcommittee found actual implementation of the QMP requirement varied significantly, from some Agency organizations that functioned under a detailed and approved QMP to some states that lacked QMPs, in their entirety. Thorough implementation of the Agency's Quality System will produce data that account for progress made towards GPRA-related objectives. This implementation should include a structured planning process (e.g., Data Quality Objective, DQO, process), project plans, and appropriate data assessment. While the DQO process cannot assure that the objectives chosen are the appropriate ones or that the tools are available to measure progress towards the environmental objectives, the DQO process can result in the ability to benchmark and measure progress in achieving objectives and therefore will increase public confidence and facilitate oversight by Congress. Data collected under an appropriate Quality System will be of known quality, and as such a determination can be made about the usability of the data in terms of their intended use. Data of unknown quality are problematic, since the data may lead to unjustified confidence and inappropriate use of the data. It is not possible to evaluate the quality of data or the quality of associated decisions, projects and activities, unless the data are generated under the auspices of a program that defines their quality. Questions such as whether a site has been cleaned, a contractor has completed a project, a facility is in compliance can not be confidently answered. d) Incomplete implementation of the Agency's Quality System precludes proper evaluation of internal and external activities, with a resulting potential for waste, fraud and abuse: The Agency's Quality System contains the necessary components to generate data of known quality. These, or equivalent components, are essential for identifying the objectives of a data-gathering activity, documenting important planning issues for subsequent implementation, and assessing the suitability of the resulting data for their intended use. When the Agency's Quality System is not properly implemented, one or more of the following events is likely to occur: When the Agency's Quality System is not properly implemented, one or more of the following events is likely to occur: (1) the objectives for collecting data are poorly or incorrectly identified, data are collected for the wrong reasons and the resulting data are of diminished value; (2) the incorrect type, too much or too little data are collected; (3) the spatial and temporal boundaries of the study are not properly defined; (4) constraints and limitations are not accounted for by the plan or during data collection; (5) the necessary degree of confidence in decision-making is not considered nor accommodated; (6) the sampling and analytical activities are not implemented according to a well-designed plan; and (7) the data are not properly assessed to determine their usability. These events result in data of unknown quality. Data of unknown quality are problematic. Typically, such data are unsuitable for decision making or determining whether a project has been successfully completed. Collecting data without adherence to the Agency's Quality System (or an equivalent system), is apt to result in data that cannot achieve the objectives for which they were intended. The Subcommittee is convinced that a more complete application of the Agency's Quality System to data collection projects will provide more usable data, better decisions, and improved oversight of internal and external data collection activities. The Quality System is designed to reduce EPA's vulnerabilities by producing data of known quality, an evidentiary trail, and reduced sampling and analytical costs (by specifying a better match between EPA's information needs and data collection). At present the potential for waste, fraud and abuse exists due to the incomplete implementation of the Quality System. e) The reporting status of the Quality System function within the Agency organization lowers the profile and diminishes the effectiveness of the Quality System: The Subcommittee's earlier letter report concluded that the Agency's current organization doesn't allow national level QA managers adequate access to the proper level of authority within the Agency (Refer to Appendix B). Additional documents examined by the Subcommittee and the Subcommittees's discussions with Agency and state personnel indicate that the problem of access also exists at the regional, program and state levels. The Subcommittee found the reporting status of the QA authority correlates with the degree to which the Quality System had been implemented. The need to have quality assurance managers report at a senior level is expressed clearly in EPA Order 5360.1, and is an accepted practice within the Quality Assurance community. "The Quality Manager shall have direct access to the highest level of management" (International Standards Organization Guide 25, "General Requirements for the Competence of Calibration and Testing Laboratories"): The need for quality assurance managers to report to a high level is also implied by the repeated requirement that the QA function be independent of those doing the work. (1) "It is highly desirable that the QA function or person be independent of the functional groups that generate the data." (40 CFR 1546.2 Contract Quality Requirements); (2) "The quality assurance unit shall be entirely separate from and independent of the personnel engaged in the direction and conduct of the study." (21 CFR 58 Federal Drug Administration and 40 CFR Part 160.35, Federal Insecticide, Fungicide, Rodenticide Act); and (3) "The QA monitoring function shall be entirely separate from, and independent of personnel engaged in direct supervision or performance of the work being monitored." (ASTM D5283-92) The predominant philosophy within the QA community emphasizes the need for independence of the QA function and direct access to the highest levels of management. It is inappropriate to argue that these accepted practices are applicable to other and lower tier organizations but not applicable to the Agency, the leading QA authority on environmental issues. The Subcommittee recommends that the Agency place the Quality System at a higher level within the Agency structure so that it can function properly and so its position reflects the importance of its role within the Agency. The Agency's ability to collect data of known quality adequate for its decisions depends upon a longterm Agency-wide commitment to quality that will withstand changes in administrations. If the Quality System is perceived as a passing management fad or a factor that can be ignored in doing the Agency's business, the Agency will remain at risk on data quality issues. f) Senior Management needs to be a champion for successful implementation of the Agency's Quality System: The Subcommittee found that the Quality Assurance Division (QAD) has generated great enthusiasm for quality assurance amongst a cadre of officials who are distributed throughout the EPA and have data collection responsibility. These are the early adopters motivated by their shared vision of the potential benefits that the Quality System can provide. To date, quality assurance has been primarily a social movement within the EPA (and associated state and tribal organizations) with QAD as the chief cheerleader. To gain wider diffusion will require senior management to implement a more complex web of persuasion, administrative mandates, and furtherance of rewarded quality practices. Studies of innovation call this moving up an "S" curve from early adopters to wider diffusion. However, these studies also indicate that most innovations fail on the rocky shoals of bureaucratic inertia. The committee is concerned that this might be a real possibility for the Quality System. Clearly, the benefits of the Quality System have not been sold to a large number of EPA officials, state and tribal officials. While this may be understandable given constraints on time and resources, it also poses dangers for the sustainability of quality assurance as a function within the Agency. The following ideas emerged in the Subcommittee's review and may assist senior management in providing the means to counter incomplete buy-in and encourage wider acceptance of the Quality System within the Agency, states and tribes: a) Consider revisiting the reporting status of the Quality System and institutionalizing it within the Agency structure. b) Create senior and lower level champions for the Quality System within EPA, states and tribal organizations. Recognize and reward those exemplars who incorporate the Quality System so other EPA, state and contractors can emulate them. The Agency may wish to expand its present QA awards program to included exemplars from the states, tribes, grantees and contractors. c) Emphasize the bench marking and oversight advantages of the Quality System as management tools and for complying with requirements such as those established by the GPRA. The Subcommittee was impressed with the potential of a wellimplemented Quality System to facilitate compliance with GPRA. A better understanding of the synergistic relationship between GPRA and an operable Quality System should advance the movement of the quality system from a peripheral activity to a central role within the Agency. d) Articulate the need to have independent oversight of the quality of the Agency's products and services and how this oversight will add to the Agency's ability to protect human health and the environment as well as to gain increased credibility and legitimacy when dealing with political leaders and the public. e) Articulate the benefits and cost reductions that will eventually accrue following incorporation of a Quality System within the Agency structure. The Subcommittee finds that the Quality System cannot be successfully implemented without buy-in and demonstrated commitment from senior management and agrees with the following quote from the ANSI/ASQC E4-1994 consensus, standard upon which the Agency's Quality System is based - "While management delegates quality management functions to staff, they cannot abrogate the ultimate responsibility for the success of the quality system." The Subcommittee also finds the Agency to be the national and international leader for quality assurance activities within the environmental community. To maintain this leadership position, and to continue to improve the data upon which environmental decisions are made, the Agency's senior management must be prepared to assign resources to the implementation of the Quality System. The Subcommittee believes that the Agency's senior management and Congress must recognize that initially, as the Quality System is implemented, there is the potential that the quality of products and services will improve at the expense of the total amount of work performed. The benefits of a Quality System have been argued to be free of costs, but the validity of this assumption is based on the amortization of costs over the longer term. While the Subcommittee can not estimate the incorporation costs, the Subcommittee is confident that the return on investment will be realized. In conclusion, the Subcommittee commends the NCERQA and QAD management for their request for a review of the Agency-wide Quality Management Program and the openness and assistance of the QAD staff who faithfully responded to our continued requests for information and answered our numerous questions. As stated in the earlier report, the above findings and recommendations attest to the significant contributions made towards the quality of data collection activities while recognizing that the job is not nearly done. Continued and increased attention from senior management is needed to implement the Quality System uniformly to all activities on an Agency-wide basis. We look forward to your response to the advice contained in this report. Sincerely, /signed/ Dr.

John Maney, Chair ENCLOSURE A CHARGE FOR REVIEW OF THE QUALITY MANAGEMENT SYSTEM a) To evaluate the relevance, completeness, and practicality of the policy and organizational components of the Agency-wide Quality System. (1) Relevance: Evaluate whether the policy and organizational components of the Agency's Quality System are applicable to the Agency's mission statement, goals (EPA/190-R-97-002) and those activities identified in Section 1.3 of the Quality Manual. (2) Completeness: Evaluate whether the policy and organizational components of the Agency's Quality System are structured such that the quality of all Agency activities needed to comply with the Agency's mission statement and goals will be monitored and assessed versus performance measures. (3) Practicality: Is the present structure of the policy and organizational components of the Agency's Quality System designed for success (i.e., will the policy and organizational levels of the Quality System properly assess and control pertinent activities and facilitate achievement of EPA goals). b) To evaluate the relevance, completeness, and practicality of the project level of the Agency-wide Quality System. (1) Relevance: Evaluate whether the project level of the Agency's Quality System is applicable to the Agency's mission statement and goals (EPA/190-R-97-002) and the covered activities identified in Section 1.3 of the Quality manual. (2) Completeness: Evaluate whether the project level of the Agency's Quality System is structured such that of all project activities needed to comply with the Agency's mission statement and goals will be monitored and assessed versus performance measures. Evaluate whether the project level guidance documents consider all essential aspects necessary to monitor and measure the quality of environmental measurement data. (3) Practicality: Is the present structure of the project level of the Agency's Quality System designed for success (e.g., are they cost-effective, efficient to implement, understandable by the intended audience, will the project level of the Quality System facilitate achievement of EPA goals). c) Use available information to evaluate the Agency's success in implementing the Agency-wide Quality System. ENCLOSURE B SUMMARY OF ISSUES NOTED TO EPA MANAGEMENT AT THE SUBCOMMITTEE'S INITIAL PUBLIC MEETING a) The need to include all activities, which have the potential to affect the quality of the Agency's products and services, under the auspices of the Quality System; b) The need for Agency management to review the appropriateness of the reporting status of the Quality System function within the Agency organization. The Subcommittee recognizes that this recommendation is of a policy nature. However, the Subcommittee believes this recommendation is justified due to the impact of reporting status on the efficacy of the Quality System; c) The lack of an Agency-wide focal point for quality issues and needed corrective actions; d) The need for Quality System training to be expanded to include the training of senior management; e) The need to identify metrics for "bench marking" existing levels of quality and changes over time; f) The need for guidance appropriate for the development and use of mathematical/computer models and the associated data; and g) The need to determine if budgeted resources for QAD are sufficient to meet the increased demand for its services. ENCLOSURE C Implementation of the Organization/Program Components of the Quality System This enclosure addresses the Subcommittee's findings, organized according to the various Quality System components that had been implemented at the time of the review. Implementation of Quality Management Plans Finding: The subcommittee felt that the sluggishness in updating QMPs was symptomatic of a more general lack of commitment to the Quality System by senior managers. Recommendation: The Subcommittee recommends that the Agency explore means of making the existence of the QMP and a summary of its contents and its significance more available to its staff. The Quality Management Plan (QMP) is the first step in creating data of known quality. The QMP provides an overview of responsibilities and lines of authority with regards to quality issues within an organization. EPA managers have described the QMP as similar to the organization's legal agreement for implementation of the Quality System. The percentage of EPA operations currently covered by QMPs is unknown. There are several Agency organizations that claim exemption from QMPs because they do not collect data as part of their function. Of those EPA organizations identified as organizations that collect data, over 90% have an approved QMP. This extent of coverage does not extend, however to the states, contractors and grantees. None of these groups is required by law or regulation to complete a QMP. EPA officials report that a minority of the groups has elected to complete a QMP. Given the fact that the states are major data sources for the EPA, the absence of a QMP by these groups is a weakness in the quality system. The Subcommittee recommends that the Agency provide incentives for states to complete their QMPs. Due to the relevance of the QMP to operations, the QMP should be a document of great interest to senior managers and a document in whose design and development they would likely want to participate. For example the QMP is the natural document for each organization to identify success criteria for the Quality System. The QMP can be the vehicle for generally linking policy goals to quality practices in data collection. Senior Managers can also use the QMP for articulating how the Quality System will be used to measure achievement of objectives, a tool, which will be helpful for management oversight and compliance with GPRA. Managers have described the QMP as one of the lesser-known documents within EPA. When quizzed, few managers had seen their QMP, much less have a familiarity with the content. More generally, the subcommittee finds that there needs to be a greater awareness of the existence and content of the QMP amongst EPA managers and staff. The Subcommittee recommends that the Agency explore means of making the existence of the QMP and a summary of its contents and its significance more available to its staff. Several EPA officials suggested the use of a web site to facilitate easy access. Finally, a barrier to successful implementation of the Quality System is the relative slowness observed in updating QMPs. This is particularly acute following reorganizations by EPA offices. The Subcommittee felt that the sluggishness in updating QMPs was symptomatic of a more general lack of commitment to the Quality System by senior managers. 2. The Implementation of Management System Reviews (MSRs) Finding: The Subcommittee found that the MSRs are a necessary component of the overall Quality System and serve the purpose of identifying problems that need to be addressed to improve the Quality System. Finding: The Subcommittee found that the delayed completion of the final MSR report decreased the overall effectiveness of the MSR. Recommendation:
The Subcommittee recommends that implementation of MSRs and completion of MSR reports should be given high priority. A major problem with the MSR process has been the timeliness of the final report. During discussions with QAMs, some had expressed the belief that MSRs would be more effective if they were more timely. In some cases it is the slow turnaround of the initial draft report; however, in others it is the fact that comments from the reviewed organization were not received in a timely fashion. While QAD has limited resources to complete the MSRs, they should be given high priority since they are the only tool available for formalizing corrective actions and giving the office/region a bench mark for improvement (following several MSRs). The Subcommittee found that the delayed completion of the final MSR report decreased the overall effectiveness of the MSR. As mentioned in an earlier report prepared by this Subcommittee (EPA-SAB-EEC-LTR- 98-003), the Subcommittee recommends that the Agency investigate whether more frequent use of MSRs would facilitate broader acceptance of the Quality System. 3. Implementation of Training Finding: The Subcommittee found the Agency's overall strategy or formal program for training in the Quality System is inadequate. Recommendation: The Subcommittee recommends that QAD provide general guidance on how to effectively identify those staff needing training, and on how to design appropriate learning activities. Recommendation: The Subcommittee recommend that QAD develop record keeping procedures and systems, so the Agency can effectively focus its resources and training capacity. Recommendation: The Subcommittee applauds the above positive efforts and urges the Agency to identify means for supporting a comprehensive training strategy and program which will ensure effective implementation of the Quality System throughout EPA. The Subcommittee found that the Agency's overall strategy or formal program for training in the Quality System is lacking. The Subcommittee's first report on the Quality System (EPASAB- EEC-LTR-98-003) recommends that the QAD develop a comprehensive strategic plan for training. Factors that are hindering EPA's ability to effectively implement the Quality System at all levels include: the lack of a long-term vision to meet the Agency's Quality training needs, the lack of clarity about QAD's and others' roles, the inconsistency of training requirements and opportunities, the infrequent tailoring of course content for the audience, the lack of wide support for course attendance, and the lack of resources allocated to training. C-4 The Quality training strategy should clearly identify: Agency-wide goals and objectives for the program; the target audiences; the type and level of training needed by job responsibilities; approaches to design and deliver effective learning experiences (e.g., courses, workshops, conferences, etc.); means to evaluate the short- and long-term effectiveness of training opportunities; the approach for consistent record keeping; and the means to obtain the ongoing resources necessary to support training. Currently, few programs, offices or regions have identified which staff and managers need Quality training or what types and levels of training would be appropriate for them. During the review, the Subcommittee was not able to locate an inventory of personnel's Quality System learning needs by job responsibilities. The Subcommittee recommends that QAD provide general guidance on how to effectively identify those staff needing training, and how to design appropriate learning activities. Not only should training be tailored to the audience's technical needs and work context, but the format of the activities should also be suitable for the audience's method of learning. For example, most adults learn more effectively when their work experiences are incorporated into the training process, and when they are actively engaged during the course. Although the Subcommittee found evidence that some trainers use exit evaluation forms to assess the audience's reactions to the training, no long-term (e.g., 3 or more months after training) evaluation processes were found. Resources could be focused on determining the longterm effectiveness of training for selected courses for different levels of staff and managers. Over time, evaluating whether attendees use the knowledge and skills they learned would provide valuable information to improve future training activities. There is very little evidence that personnel are aware of what training is available. There appears to be no systematic record keeping of who has been trained or which courses were offered, even when specific courses are required of specific staff. Throughout most of the Agency, records are insufficient to assure that training needs are either inventoried or met. The Subcommittee recommend that QAD develop record keeping procedures and systems so the Agency can effectively focus its resources and training capacity. Where Quality System responsibilities have been decentralized, the number of personnel involved in Quality and requiring training has increased. This situation presents a particular challenge for the Agency when resources allocated for training activities are very limited. It is important to consider the extent of resources required to support decentralized Quality systems. Strategies need to be developed to obtain the essential resources for training to implement a successful Quality System. The Subcommittee noted some exemplary training initiatives, which were exceptions to the above concerns. In one region, technical staff recognized specific training needs and, above and beyond their routine duties, committed their time, expertise and energies to meet the needs. Some regions reach out to state, tribe and contract staff to invite them to training activities. C-5 Others conduct monthly conference calls or meetings to ensure that lessons learned are shared broadly. The Subcommittee recognizes that QAD staff understand the importance of tailoring courses to the audience's responsibilities and work context. They have begun to design training guidance, modules and materials more targeted to the audience's routine work. In collaboration with staff from one office, QAD is developing a new approach to address training concerns. The Subcommittee applauds the above positive efforts and urges the Agency to identify means for supporting a comprehensive training strategy and program which will ensure effective implementation of the Quality System throughout EPA. 4. Implementation of the Quality Assurance Annual Report and Work Plan Recommendation: The Subcommittee recommends that the Agency encourage all organizations to complete QAARWPs in a timely manner and that the content of these QAARWPs be sufficient for the bench marking of quality, the measurement of changes in quality and the planning of the Quality System. (2) a mechanism for raising the visibility of QA issues within an organization and on an Agency-wide level; (3) a mechanism for bench marking quality and changes over time; and (4) a platform for recognizing accomplishments related to QA. While the EPA Quality Manual emphasizes the importance of the QAARWP to the Agency's Quality System, interviews indicated that compliance with its annual requirement was variable across organizations. In fact, information presented to the Subcommittee indicates that 1997 was the first year that all 10 regions submitted a QAARWP and of the regions, research labs, centers and offices that complied, the content and usefulness of the QAARWPs varied. In response to QAD's encouragement and critiques, organizations have, over time, improved the content and value of the average QAARWP. However, the Subcommittee recommends that the Agency encourage all organizations to complete QAARWPs in a timely manner and that the content of these QAARWPs be sufficient for the bench marking of quality, the measurement of changes in quality and the planning of the Quality System. Finding: The Subcommittee found that a lack of statistical expertise was a barrier to implementation of the DQO process. Recommendation: The Subcommittee recommends that the Agency develop training in, and guidance for, stakeholder identification and participation. Systematic planning is required by Order 5360.1 to develop acceptance or performance criteria for all operations generating environmental data. The elements of a systematic plan are listed in Section 3.3.8 of the EPA Quality Manual. The EPA Quality Manual also recommends that this required planning be conducted using EPA's Data Quality Objectives (DQO) Process. Detailed guidance in the use of the DQO process has been provided in Guidance for the Data Quality Objectives Process (QA/G-4), (EPA/600/R-96/055) and supplemental guidance in Data Quality Objectives Process Decision Error Feasibility Trials, DQO/DEFT (QA/G-4D), (EPA/600/R- 96/056). The Subcommittee found the DQO process to be relevant, nearly complete and certainly practical as indicated in the Subcommittee's letter report (EPA-SAB-EEC-LTR-98-003). However, the Subcommittee found adoption of the DQO process by EPA's regions, program offices, the states and tribes has been sporadic to nonexistent. The DQO process apparently has been adopted by the Department of Energy (DOE) for planning the clean up of DOE facilities, indicating that a large government agency can incorporate a structured planning process into their environmental program. However, acceptance and use of the DQO process by the Agency's regions and program offices varies greatly even though training has been provided on the basics of the process. Reasons frequently given for not using the DQO process can be classified as one of three principal categories: administrative, psychological and technical. With regard to the administrative barriers, the Subcommittee found that there are no demonstrable rewards or punishments for respectively applying or not applying the DQO process (or its equivalent) in the environmental data collection planning process. The lack of a requirement to employ the DQO planning process, and the lack of demonstrable consequences for those who do not, may have led to indifference on the part of some project managers. With regard to psychological barriers, anecdotal information indicates that a fear of admitting that decision errors are possible or a desire to avoid the responsibility associated with defining a tolerable decision error are reasons for avoiding the DQO process. Although the risk of making a wrong decision based on environmental sampling data has always been present, the DQO process requires that this risk be explicitly stated and quantified. For many project managers, this approach represents a paradigm shift in project planning. Most project managers would readily agree that there are errors associated with both analytical and sampling procedures, but admitting that these errors may lead to wrong decisions may be disquieting to them. The psychological barriers to quantification of the tolerable potential decision error may be overcome through involvement of all stakeholders in the planning process and consensus-based decision-making. The Subcommittee recommends that the Agency develop training in, and guidance for, stakeholder identification and participation. In addition, the Subcommittee's recommends that in future revisions to the applicable guidance documents (G-4 and G-4D) QAD more clearly emphasize that correct decisions will be made most frequently when systematic planning such as the DQO process is employed. Attempts at using the DQO process often stop short of implementing the complete process. Technical barriers are often a major impediment to the implementation of the DQO process. For example, project managers perceive the DQO process to be inflexible and frequently fail to comprehend and apply Step 6 "Specify Tolerable Limits on Decision Errors." Part of the cause for not readily employing Step 6 is that some project managers feel uncomfortable with the statistical nature of this step. To properly specify limits on decision errors requires recognition on the part of the project manager that the probability of making an incorrect decision can be statistically controlled. However, a general lack of appreciation for the consequences of ignoring potential decision errors and a lack of awareness of the added value of the DQO process still persist. For those project managers who are uncomfortable with statistical analysis, the DQO training should be tailored to include a statistical component together with practical examples that illustrate the impact of establishing decision error probability limits on sampling design and costs. 2. Implementation of the Quality Assurance Project Plans (QAPPs) Finding: The Subcommittee found that while QAPPs are not uniformly employed, the frequency of QAPP usage is significant; yet anecdotal information indicates that QAPPs frequently lack the project specific details necessary for successful implementation. Because of the potential misuse of generic QAPPs as well as improperly prepared QAPPs, the EPA document QA/G-5 provides a checklist to assist quality assurance (QA) managers in their review of submitted QAPPs. It is unclear to what extent QA managers use this checklist in screening the accuracy and completeness of QAPPs. However, if the checklist were used routinely, improperly prepared or incomplete QAPPs should be readily identified and corrected. In summary, the Subcommittee found that while QAPPs are not uniformly employed, the frequency of QAPP usage is significant; yet anecdotal information indicates that QAPPs frequently lack the project specific details necessary for successful implementation. 3.
Implementation of Data Quality Assessment Guidance
Finding: The Subcommittee found a general lack of awareness by regional, state, and grantee personnel for the G-9 document, its content, and application. Regarding how well the G-9 guidance has been implemented; there is limited anecdotal and factual evidence to evaluate its application to the Agency's data collection operations. As a result of interviews however, the Subcommittee found a general lack of awareness by regional, state and grantee personnel for the G-9 document, its content and application; and that a lack of statistical expertise, as for Step 6 of the DQO process, was a barrier to implementation.
