The Department of Mines and Energy, South Australia (DME) contracted Michael Williams and Associates Pty Ltd to audit the environmental management of seismic exploration operations in the South Australian Otway Basin. The audit was carried out in early 1992 and covered petroleum exploration operators and DME environmental management systems. An innovative field sampling technique was developed to compare the environmental impact of two different seismic line clearing techniques. Recovery of native vegetation as measured by vegetation structure was also quantified.The audit found DME to have a dynamic and integrated environmental management system while company systems varied in standard. Wide consultation assisted the audit process.As a result of clearing for agriculture, native vegetation covers only six per cent of the Otway Basin. With the strict limitations to broad-scale vegetation clearance since the mid-1980s and the cessation since 1991, the greatest environmental impact of seismic exploration is the clearance of native vegetation for access by seismic vehicles. Native vegetation structure and associated abiotic variables on seismic lines and adjacent control sites, were subject to a classification and ordination analysis which compared the impact of seismic lines constructed by bulldozer or Hydro-ax (industrial slasher). Post-seismic recovery rates of three different vegetation associations were also determined. This analytical technique permits the effects of seismic line clearance to be compared with the natural variability of specific vegetation associations within a region. In interpreting the results however, there is a confounding effect of line type and year as most of the more recent seismic lines were constructed using a Hydro-ax. Results indicate that Hydro-ax clearing affects vegetation structure less than bulldozing. Most Hydro-ax sites recovered within a few years whereas some sites, bulldozed as early as 1971, particularly tussock grasslands, have not yet recovered.This study provides a significant break-through in the debate about the persistence of seismic impacts on native vegetation. As a rapid preliminary assessment, sampling vegetation structure rather than floristics, provides a cost-effective audit and monitoring technique which can be used by non-specialists in a range of petroleum exploration environments. Any significant structural differences may require more detailed analysis to determine if floristic composition also differed.

Abstract Oil and gas exploration has resulted in over 300,000 km of linear disturbances known as seismic lines, throughout boreal peatlands across Canada. Sites are left with altered hydrologic and topographic conditions that prevent tree re-establishment. Restoration efforts have concentrated on tree recovery through mechanical mounding to re-create microtopography and support planted tree seedlings to block sightlines and deter predator use, but little is known about the impact of seismic line disturbance or restoration on peatland carbon cycling. This study looked at two mounding treatments and compared carbon dioxide and methane fluxes to untreated lines and natural reference areas in the first two years post-restoration. We found no significant differences in net ecosystem CO2 exchange, but untreated seismic lines were slightly more productive than natural reference areas and mounding treatments. Both restoration treatments increased ecosystem respiration, decreased net productivity by 6–21 gCO2m− 2d− 1, and created areas of increased methane emissions, including an increase in the contribution of ebullition, of up to 2000 mgCH4m− 2d− 1. Further research on this site to assess the longer-term impacts of restoration, as well as application on other sites with varied conditions, will help determine if these restoration practices are effective.

A synthetic seismic section was modelled to help in the interpretation of Cooper Basin seismic lines which cross major faults and exhibit shadow zones.A major fault bounding the northwest flank of the Packsaddle Structure in the Merrimelia-Innamincka Farmout Block in South Australia was selected for modelling. A geological cross-section postulated on the basis of wells on either side of the fault was fed into the seismic modelling package AIMS (Advanced Interpretive Modelling System — licensed by Geoquest International Inc.) to produce a synthetic seismic line. This synthetic line provided a realistic match with an actual seismic line across the fault. Pre-stack migration of the actual seismic data is suggested to provide additional evidence for the reliability of the model.The shadow zone in the synthetic section is caused by dipping events in the fault shadow zone created by compaction of the Toolachee and Patchawarra Formations along the hanging wall of the fault plane. The dipping events cause reflected energy to be detected outside the fault zone. The large component of compaction within the Permian section is largely ascribed to thick coal horizons. The possibility of petroleum traps in the hanging wall of the fault is inferred and drilling is recommended.

The Impact

The tsunami which devastated Japan in 2011 highlighted the consequences of natural disasters on an area considered to be "best prepared" for such an event. Learning from the direct environmental, social and economic impacts and temporally and spatially displaced indirect global impacts, is important. When seeking to identify and mitigate the impact of proposed developments the process is carried out from two distinct perspectives: "before" and "after" implementation with environmental impact assessment and environmental management the main "instruments" on either side. Drawing on examples from financial institutions and disaster response agencies, this paper explores the theory that coupling the two "instruments" can aid disaster risk reduction and management. It concludes that there is no simple answer and that further research is needed to inform practice.

Space Activities

The environmental legislation of the Russian Federation does not fully regulate the impact on the environment during the creation and operation of rocket and space technology. The impact of carrier rockets launches on the environment is currently not standardized: there is no payment for negative environmental impact, there are no impact regulations. The legislation of the Russian Federation does not provide for environmental monitoring of spaceports and rocket stages drop zones. The commissioning of the Vostochny Cosmodrome requires solving the accumulated problems on environmental management issues in the implementation of rocket and space activities. Additional difficulties arise during the operation of the Baikonur Cosmodrome located on the territory of the Republic of Kazakhstan due to differences in approaches to the environmental management in the Republic of Kazakhstan and the Russian Federation. The analysis of the regulatory acts of the two states in terms of applicability to the rocket and space activities has shown that the improvement of the regulation of this type of anthropogenic impact on the environment is easier to implement within the Kazakhstan legislation. It would be advisable to have uniform requirements for space complexes in their development and operation within the environmental legislation of the CIS member states.

This report examines the recovery rates of 3D seismic lines in the Cooper Basin, SA, 1992–2015. There are now more than 70,103 km of 3D seismic line in the Cooper Basin. There are a variety of impacts caused by seismic exploration, with the visual impact being the prime concern raised by stakeholders. The recovery rates of 3D seismic lines vary between differing land systems. Some land systems, such as dune and floodplain, are dynamic, while others, such as gibber plain, are less so. A historical database consisting of 2,018 videos and photographs was used to score the visibility of seismic lines at various locations and times. A new methodology of visually scoring this data was created, using a scale ranging from 1 (the survey dominates the landscape) to 5 (the survey is no longer visible). Data analysis showed that seismic lines in dune land systems are likely to recover within seven years, seismic lines in floodplain land systems are likely to recover within eight years, and seismic lines in gibber plain land systems are likely to take 10–20 years to recover to a visibility score of 4 or 5. To arrive at a more accurate determination of seismic line recovery in salt lake, wetland and tableland land systems, more extensive data collection is recommended.

During the past five years, the Onshore Energy Security Program, funded by the Australian Government and conducted by Geoscience Australia, in conjunction with state and territory geological surveys, has acquired deep seismic reflection data across several frontier sedimentary basins to stimulate petroleum exploration in onshore Australia. This extended abstract presents data from two seismic lines collected in Western Australia in 2011. The 487 km long Yilgarn-Officer-Musgrave (YOM) seismic line crossed the western Officer Basin in Western Australia, and the 259 km long, Southern Carnarvon Seismic line crossed the Byro Sub-basin of the Southern Carnarvon Basin. The YOM survey imaged the Neoproterozoic to Devonian western Officer Basin, one of Australia's underexplored sedimentary basins with hydrocarbon potential. The survey data will also provide geoscientific knowledge on the architecture of Australia's crust and the relationship between the eastern Yilgarn Craton and the Musgrave Province. The Southern Carnarvon survey imaged the onshore section of the Ordovician to Permian Carnarvon Basin, which offshore is one of Australia's premier petroleum-producing provinces. The Byro Sub-basin is an underexplored depocentre with the potential for both hydrocarbon and geothermal energy. Where the seismic traverse crossed the Byro Sub-basin it imaged two relatively thick half graben, on west dipping bounding faults. Structural and sequence stratigraphic interpretations of the two seismic lines are presented in this extended abstract.

The article analyzes the process of adaptation of the national legislation to the European standards in accordance with the Association Agreement between Ukraine and the EU. In particular, in the sector “Environmental management and integration of environmental policy in other sectoral policies”, the implementation of Directive 2001/42/EC on the assessment of the effects of certain plans and programs for the environment and Directive 2011/92/EC on the assessment of the impact of certain public and private projects on the environment was considered. The influence of environmental management tools and the integration of environmental policy on other sectoral policies have been determined and their interrelation with the rest of the sectors in the field of environmental protection has been established. It has been established that environmental assessment is the main instrument for ensuring environmental considerations in the development of plans and programs and contributes to sustainable development through the promotion of environmental protection issues in economic and social development.The procedures of strategic environmental assessment and environmental impact assessment have been characterized; their subjects and objects have been clarified. The peculiarities of these procedures, stages and advantages of their application in the national practice of public environmental management are presented. The way of implementation of strategic environmental assessment and environmental impact assessment at the level of the European community is considered, and examples of their practical application at the level of the EU member states are presented.It is indicated that strategic environmental assessment and environmental impact assessment are procedural tools used to prevent any possible negative effects of economic activity on the environment and public health. A comparative analysis of these procedures was carried out and links and differences were identified. It has been proved that the effectiveness of strategic environmental assessment in preventing environmental hazards is significantly higher than environmental impact assessments. The problem aspects and perspectives in the field of practical implementation of legislation in the field of environmental assessment in Ukraine are highlighted.

The Onshore Energy Security Program—funded by the Australian Government and conducted by Geoscience Australia—has acquired deep seismic reflection data in conjunction with state and territory geological surveys, across several frontier sedimentary basins to stimulate petroleum exploration in onshore Australia. Here, we present data from two seismic lines collected in SA and NT. Seismic line 08GA-OM1 crossed the Arckaringa and Officer basins in SA and the southern-most Amadeus Basin in NT. Seismic line 09GA-GA1 crossed the northeastern part of the Amadeus Basin and the complete width of the southern Georgina Basin in NT. Structural and sequence stratigraphic interpretations of the seismic lines will be presented here, followed by an assessment of the petroleum potential of the basins. Seismic line 08GA-OM1 also crosses the Neoproterozoic to Devonian eastern Officer Basin. The basin is structurally complex in this area, being dominated by south-directed thrust faults and fault-related folds—providing potential for underthrust petroleum plays. The northern margin of the basin is overthrust to the south by the Mesoproterozoic Musgrave Province. To the north, the Moorilyanna Trough of the Officer Basin is a major depocentre of up to 7,000 m deep. Both seismic lines cross parts of the eastern Amadeus Basin. Seismic line 08GA-OM1 shows that the southern margin of the basin is overthrust to the north by the Musgrave Province with the main movement during the Petermann Orogeny. In the northeast, seismic line 09GA-GA1 crosses two parts of the basin separated by the Paleoproteroozic to Mesoproterozoic Casey Inlier (part of the Arunta Region). The northern margin of the basin is imaged seismically as a southward-verging, thinned-skinned thrust belt, showing considerable structural thickening of the stratigraphic succession. Seismic line 09GA-GA1 was positioned to cross that part of the southern Georgina Basin that was considered previously to be in the oil window. Here, the basin has a complex southern margin, with Neoproterozoic stratigraphy being thrust interleaved with basement rocks of the Arunta Region. The main part of the basin, containing a Neoproterozoic to Devonian succession, is asymmetric, thinning to the north where it overlies the Paleoproterozoic Davenport Province. The well, Phillip–2, drilled adjacent to the seismic line, intersected basement at a depth of 1,489 m, and has been used to map the stratigraphic sequences across the basin.

Environmental Management Practice

In early 1986 the APEA Environmental Affairs Committee developed an environmental policy to provide a framework for the Association's response on environmental issues which affect the petroleum industry. To fulfil the aims of this document there is a need for member companies to assist the committee in addressing and promoting the industry's environmental management aims. Environment is defined in broad terms in current legislation. To embrace this definition, APEA must adopt a position that reflects the industry's desire to be represented at the policy review stages of such environmental issues as land use proposals. Since 1971 only eight papers in the APEA Journal have addressed environmental issues. Companies have generally not shared or promoted their individual responses to such issues, although there would be value to the industry as a whole through identifying and discussing environmental management expertise and experience within APEA. Two examples of environmental management practice applied by CSR in Delhi Petroleum's activities in South Australia and Queensland are discussed: a demonstration seismic line within the Witjira National Park, South Australia and the use of rollers for seismic line preparation. Similar examples can probably be identified for all member companies. In generating a pool of operational examples, APEA might better represent the industry's ability and record in this field to governments and to the general public.

The Impact

Every year the impact on natural environment is more due to consumption of natural resources for large infrastructure and construction projects. Even though by implementing modern construction techniques and low cost effective materials the volume of impact reduction is not efficient. India is a country which has enormous natural resources and it has been utilized for large infrastructure and construction projects which makes an environmental impact. This present paper focuses on planning and formulation of Environmental Management System (EMS) to reduce the environmental impact due to large infrastructure and construction projects. The planning of EMS is done based on the environmental impact checklist provided by Ministry of Environmental and Forest Climate change (MoEF&CC) under Government of India and the Formulation is done through PERT and CPM techniques which is to implement EMS in short duration to reduce environmental impact through large infrastructure and construction projects. Finally, the Planning and Formulation of EMS gives solution to reduce more volume of environmental impacts due to large infrastructure and construction projects.
