Significance and Use
HACCP is a proactive management tool that serves to reduce hazards potentially expressed as adverse biological or environmental effects, for example, associated with chemical releases, changes in natural resource or engineering practices and their related impacts, and accidental or intentional releases of biological stressors such as invasive species.
Sequential implementation of HACCP and feedback in the iterative HACCP process allows for technically-based judgments concerning, for example, natural resources or the use of natural resources. Implementing the HACCP process serves to reduce adverse effects potentially associated with a particular material or process, and provides guidance for testing and evaluation of products or processes, through a pre-emptive procedure focused on information most pertinent to a system’s characterization. For example, identification of CCPs assure that processes and practices can be managed to achieve hazard reduction. For different processes and situations, HA may be based on substantially different amounts and kinds of, for example, biological, chemical, physical, and toxicological data, but the identification of CCPs serving to reduce hazard is key to successful implementation of HACCP.
HACCP should never be considered complete for all time, and continuing reassessment is a characteristic of HACCP evaluations, especially if there should be changes in, for example, production volumes of a material, or its use or disposal increases, new uses are discovered, or new information on biological, chemical, physical, or toxicological properties becomes available. Similarly, HACCP should be considered an ongoing process serving as a key component in engineering practices, for example, related to construction activities and land-use changes, and natural resource management practices, for example, related to habitat use, enhancement, and species introductions such as fish-stocking programs. Periodic review of a system’s performance will help assure that new circumstances and information receive prompt and appropriate attention.
In many cases, consideration of adverse effects should not end with completion of the HA and identification of CCPs key to the development of control measures. Additional steps may subsequently include risk assessment, and decisions concerning acceptability of identified hazards and risks, and mitigation actions potentially applicable to the process or practice that initially motivated HACCP.
Scope
1.1 This guide describes a stepwise procedure for using existing information, and if available, supporting field and laboratory data concerning a process, materials, or products potentially linked to adverse effects likely to occur in the environment as a result of an event associated with a process such as the dispersal of a potentially invasive species or the release of material (for example, a chemical) or its derivative products to the environment.
1.2 Hazard analysis-critical control point (HACCP) evaluation is a simple linear process or a network of linear processes that represents the structure of any event; the hazard analysis (HA) depends on the data quality and data quantity available for the evaluation process, especially as that relates to critical control points (CCPs) characterized in completing HACCP. Control measures target CCPs and serve as limiting factors or control steps in a process that reduce or eliminate the hazards that initiated the HACCP evaluation. The main reason for implementing HACCP is to prevent problems associated with a specific process, practice, material, or product.
1.3 This guide assumes that the reader is knowledgeable in specific resource management or engineering practices used as part of the HACCP process. A list of general references is provided for HACCP and implementation of HACCP and similar methods, as those apply to environmental hazard evaluation, natural resource management, and environmental engineering practices (8, 11-17, 20, 21, 24, 27, 28, 30-32).
1.4 This guide does not describe or reference detailed procedures for specific applications of HACCP, but describes how existing information or other empirical data should be used when assessing the hazards and identifying CCPs potentially of use in minimizing or eliminating specific hazards. Specific applications of HACCP evaluation are included as annexes to this standard, which include implementation of HACCP in resource management practices related to invasive species control and mitigation.
1.5 HACCP evaluation has a well developed literature in, for example, food science and technology, and in engineering applications (see, for example, 8, 11, 12, 14, 16). As a resource management tool, HACCP is relatively recent in application to the analysis of hazards to aquatic, wetland, and terrestrial habitats and the organisms occupying those habitats. Most of the guidance provided herein is qualitative rather than quantitative, although quantitative methods should be applied to any hazard analysis when possible. Uncertainties associated with the analysis should also be characterized and incorporated into the HACCP evaluation when possible (see, for example, 1-10, 18, 19, 29).
1.6 This standard provides guidance for assessing hazard but does not provide guidance on how to take into account social or political considerations that influence the specification of the acceptability of the hazard. Judgments concerning acceptability are outside the scope of this guide, but available guidance from ASTM is applicable to this process (see E2348 Standard Guide for Framework for a Consensus-based Environmental Decision-making Process).
