  • 2. Abstract ENVIRONMENTAL AUDITING IN A SUSTAINABLE SETTING IN MALAYSIA. By Subramaniam Karuppannan,(MCIEH), 1 1 Environmental Health and Safety Department, Faculty of Health Sciences, UiTM Puncak Alam.Introduction: Environmental impact assessment is a mandatory assessment for anyplanned activity using environmental protection requirements with sustainabledevelopment, while determining optimum solutions. Environmental audit is themandatory assessment of the compliance of environmental management andperformance of operating business with environmental protection requirements. Theconcept of environmental auditing is closely related to monitoring, norms and standards(GDRC, 2010).Methodology: Environmental audits were done at selected sites to test theeffectiveness of environmental management efforts at local levels. Environmental auditsare systematic and independent reviews to check the results of environmentalmeasurements on air, water, effluents, noise and waste (including pests) to meetproposed set targets, while focusing on methods used and reviewing EIA documents tosee whether there are any deviations between targets (legal requirements) and results.Environmental sampling and testing was done in a selected EIA project site includinginterviewing local residents.Results and discussion: Air sampling results complied the environmental standardswith no violations of the EQ (Clean Air) Regulations, 1978. The water samples (n=5)showed that violations were for Arsenic (n=3), Lead and Nickel (n=5) for the EQ (SIE)Regulations, 2009. Study on waste characteristics by gravimetric method (n=5) hadresults for plastics=38%, paper=32%, organic (food waste) =29% and aluminum =1%.Pest data identified common house flies (musca domestica) (n=111). The pest may havebeen encouraged by the presence of organic waste. The noise sampling (n=4) for daytime showed results for all points were exceeding the maximum permissible sound levels(PSL) and night time sampling (n=3) that exceeded standards showed some violationand mostly due to non point sources probably due to vehicles. Traffic impactassessment showed that the majority of vehicles were cars followed by motorcycles,lorry and buses. The public survey (n=100) among respondents revealed that theresidents were not so concerned about the health effects related to projects, butexpressed dissatisfaction on air pollution issues (dust problem).Conclusion: The environmental audit showed that traffic problem is a serious issue withrisk evaluation for traffic as extremely high. The residents were encouraged to use publictransport and construction of motorbike lanes with adequate signage. Water qualityneeds to be maintained and waste management must be improved to avoid pestproblems. Noise needs to be monitored with controls. Extended monitoring is requiredbefore and after project development is finish to minimize environmental and healthimpact.Key words: Environment Impact Assessment (EIA); Environmental Quality Act 1974(EQA).
  • 3. 1. Introduction• Environmental impact assessment (EIA) is a mandatory assessment (Section 34A of EQA 1974 for any planned activity using environmental protection requirements within sustainable development, while determining optimum solutions (DOE, 2011).
  • 4. 1. Introduction• Environmental audit (EA) is the mandatory assessment (Sec.33A of EQA 1974) of the compliance of environmental management and performance of operating business with environmental protection requirements (DOE, 2011).• The concept of environmental auditing is closely related to monitoring, norms and standards (GDRC, 2010).
  • 5. 1. Introduction• Risk assessment is used to assess hazards from a project.• HIRARC is a common tool used in Safety and Health assessments in the workplace (DOSH, 2008).• QRA is used to assess a potential residual risk from hazards in a project with environmental impacts and need strict monitoring and surveillance (DOE, 2004).
  • 6. 1. Introduction• Hazard identification: • Physical - air / water / accidents / etc • Chemical - heavy metals / aerosols / etc • Biological hazards – Viruses / Bacteria / Parasites / Fungi / etc• Risk assessments: • Assess residual risks after hazard controls • Qualitative RA versus Quantitative RA (Quan RA) (Quan• Risk controls: • Risk management / Risk Communication (DOE, 2004).
  • 7. 2. Background• The new campus of UiTM Puncak Alam is located in Bandar Puncak Alam, about 50 kilometres drive Alam, from Kuala Lumpur.• An approved EIA project in 2008 located on Lot 1620 (PT 1657) and Lot 1621 (PT1658) Mukim Jeram, Jeram, Kuala Selangor.• Expected to accommodate about 20,000 students, and 5,000 staff.• Water use = 2 million gallon per day• Electricity expected at 42.56 MW per day.
  • 8. 2. Background• Topography is hilly where the slope steepness ranged from 0° to 45°. 0° 45°• Most of the project consisted of forest, with the eastern side of the project situated next to Bukit Cherakah Reserve Forest.• The developer is TriPlc (a joint venture company) that ventured into construction business in 2003.• It began with construction of academic blocks and students accommodations for UiTM Puncak Perdana, Perdana, Section U10, Shah Alam Selangor and later UiTM Puncak Alam. Alam.
  • 9. 2. Background• TriPlc secured a new contract valued at RM1.0 billion for construction of UiTM Puncak Alam Campus for Faculty of Health Science, Faculty of Pharmacy and Student Plaza consisting of: a) infrastructure work, b) hostels for students complete with recreational and sports facilities, c) academic buildings and facilities.• TriPlc is also developing the balance 600 acres mixed development project in Section U10, Shah Alam, Alam, Selangor.
  • 10. 2. Background• TriPlc in May 2010 was granted a 23-year 23- concession to undertake the construction and maintenance of Phase 2 works of UiTM Puncak Alam Campus consisting of: a) 3 faculties to accommodate not less than 5,000 students, hostel accommodation for 2,500 students b) 10 units of fellow accommodation, multipurpose hall, maintenance centre, prayer hall, library, student centre, cafeteria and health centre.
  • 11. 3. Methodology• Environmental audits were done for Post EIA monitoring at selected sites to test effectiveness of environmental management efforts at local levels.• Quantitative RA (DOE, 2004) and referred to HIRARC (DOSH, 2008).
  • 12. 3. Study Location
  • 13. 3. Methodology• Environmental audits - systematic and independent reviews to check the results of environmental measurements on: – air, water, effluents, noise and waste (including pests) to meet proposed set targets, – Measurements : direct and indirect• Focus on methods used and reviewing EIA documents to see whether there are any deviations between targets (legal requirements) and results.
  • 14. 3. Methodology• Environmental sampling and testing was done in a selected EIA project site including interviewing local residents.• Sampling and analyses were done for drinking water, river water, air, noise, pests and waste.
