SECTION 6: REMEDIATION ASPECTS1. Which remediation technologies could be appropriate?2. What are the main constraints and advantages to each of the applicable remediationtechnologies/engineering methods?3. What are the anticipated perception/community impacts of the remediation technologies?4. How can the remediation process be validated?SECTION 7: HEALTH AND SAFETY1. In what way are health and safety considerations influenced by the nature of acid tarlagoons?2. What are the specific issues for selection of working methods?3. What are the specific issues for selection of personal protective equipment?1.4 Risk Communication IssuesPublic awareness of contamination issues, together with the general perception of associatedrisks and the potential for harm (in the conventional sense) has increased during the 1980s and1990s. Useful guidance with respect to risk communication issues can be found inEnvironment Agency R&D <strong>Technical</strong> Report P142 “Communicating Understanding ofContaminated <strong>Land</strong> Risks” (SNIFFER 1999).R&D <strong>Technical</strong> Report P5-042/TR/04 4
1.5 Linkages Between the <strong>Guidance</strong> Reports and the Special SiteCategoriesMany of the Special Site categories are likely to include technical aspects that areincorporated into more than one of the seven individual guidance reports. A matrix showingthe links that may be relevant between the guidance reports and the Special Site categories isgiven below in Table 1.1.Table 1.1 - Linkage between guidance reports and Special Site categoriesReports in This Series of Particular Relevanceto Each Special Sites CategorySpecial Sites Categories(for full definitions see the Contaminated<strong>Land</strong> (England) Regulations 2000)P5-042/TR/1 MOD <strong>Land</strong>P5-042/TR/2 Chemical WeaponsP5-042/TR/3 ExplosivesManufacturingP5-042/TR/4 Acid Tar LagoonsP5-042/TR/5 PetroleumRefineriesP5-042/TR/6 NuclearEstablishmentsP5-042/TR/7 PrescribedProcesses Designated for CentralControlRegulation 3 <strong>Land</strong>land to which Regulation 3 applies is dealt withseparately from this series of reportsAcid Tar Lagoons √ √Petroleum Refineries √ √ √Explosives Manufacturing orProcessing SitesPrescribed Processes Designatedfor Central Control√ √ √ √ √√ √ √Nuclear Licensed Sites √ √ √ √Current Naval, Military and AirForce <strong>Land</strong>√ √ √ √ √Chemical Sites √ √ √AWE Sites √ √ √S.30 of the Armed Forces Act<strong>Land</strong>√ √ √R&D <strong>Technical</strong> Report P5-042/TR/04 5
