Page 2 Langsat Terminal (One) Environmental Auditing & Health Impact Assessment 2011 Executive Summary Introduction The EIA on Langsat Terminal (One) (LgT-1) has been written and approved on 2007. The plant was developed in three phases. The first phase started it operation with 7 storage tanks for 130,000 m 3 gasoil (middle-distillates) and naphtha. Then in April 2010, the second phase started it operation with the additional of 13 storage tanks for 270,000 m3 fuel oil and gasoil. Recently, in June 2011, the final phase achieved it construction completion. Once it operated (assume in early 2012), 76,000 m 3 biodiesel and gasoline will be stored in another 12 storage tanks. The operation of LgT-1 will only involve in loading/unloading petroleum from/to the vessel berthing at Tanjung Langsat Port, blending/mixing middle-distillates oil, inter-tank transferring and distribution to land transportation. Literature Review According to World Bank Group (2007) and G.S. Cholakov ( ), the most environmental and health hazard emit from a storage plant of oil and gas (O&G) related industries are noise, effluent and ground water pollution and the most important is air pollution as the plant may release a lot of volatile organic compound to the air from the air stack of the thermal boiler, land and vessel emission, as well as atmosphere pressure released from the valve at the tank rooftop. All these kind of hazards has a significant risk to the public health of the worker, nearby residents as well as the fauna surrounds. The main concerned that built in mind is that once accidents occurred, especially explosion and burn as the highest result of Qualitative Risk Assessment done in Rjinmond Industrial Area is about the pool fire, because it not only result in flame danger but also the effect rise from the emission of the smoke and spread-gases into the atmosphere. Mohd Ruhaizie R., Noradillah A.R., Siti Mashalida J. & Siti Aishah M. Bachelor Degree in Environmental Safety & Health (Hons.) Page 3 Langsat Terminal (One) Environmental Auditing & Health Impact Assessment 2011 Methodologies Site visit, public survey and secondary data collection was done from prior the measurement with site visit and public survey (100 respondents) have been done on November 8 – 11, 2011. Measurement of air quality (2 locations), noise exposure (2 locations same as air quality measurement location) and ground water quality (2 locations) and the observation of the waste management plan and records (secondary data) were done from November 23 – 26, 2011. Result Boundary noise exposure (L Aeq ) at both location are N1: 68.2 dB(A), N2: 58.0 dB(A) during daytime and N1: 52.3 dB(A), N2: 48.1 dB(A) at night-time. For air quality at both 3 3 3 3 locations, TSP (A1: 94.3 µg/m , A2: 98.1 µg/m ), SO 2 (A1: 17.2 µg/m , A2: 19.7 µg/m ) while for SO 2 and VOC are not detected (ND) at both locations. For ground water quality, temperature (GW1: 28.7°C, GW2: 28.4°C), pH (GW1: 6.01, GW2: 6.23), DO (GW1: 3.66 mg/l, GW2: 3.15 mg/l), BOD (20°C) (GW1: 3 mg/l, GW2: 2 mg/l), COD (GW1: 31 mg/l, GW2: 24 mg/l), TSS (GW1: 21 mg/L, GW2: 12 mg/l) and Ammonium Nitrate (GW1: 0.34 mg/l, GW2: ND). For public survey, majority mention that they haven’t experienced any major health problem due to the operation of the plant. Risk Assessment After the hazard identification done and qualitative risk were analyzed, we’ve found that the greatest risk from the plant is due to the pool fire, which might be emit from the leakage of the pipeline and tanks, due to overpressure, corrosion and misleading action of the workers. Mohd Ruhaizie R., Noradillah A.R., Siti Mashalida J. & Siti Aishah M. Bachelor Degree in Environmental Safety & Health (Hons.) Page 4 Langsat Terminal (One) Environmental Auditing & Health Impact Assessment 2011 Discussion and Conclusion No result showing that any of the parameters measured violence any standard limits either The Planning Guidelines for Environmental Noise Limits and Control DOE 2004, Recommended Malaysian Air Quality Guidelines (RMAQG), 1988 or Schedule B, Malaysian Environmental Quality (Sewage) Regulation 2009. As supported by the opinion in public survey, it is concluded that the operation of this plant is harmless to the human and environment regarded to the safety and health, as long as all operations and tasks done followed the standard operating procedures (SOP) of the plant and it emergency response plant (ERP). Recommendation As data shows that result are below allowable limit and the QRA done support that the most danger coming from the pool fire occurrence, therefore the plant should continue its EMP as planned. More training will ensure that the ERP will be execute and working accordingly during the emergency time. It’s also suggested that the plant should has discharge water and effluent treatment plant as the Accidentally Oily Contaminated water can occur but the containment itself might not enough to reduce the risk of the accumulated oily that accidently contaminated the water. More than that, the treatment plant is also a requirement in achieving ISO 14000:2008 recognition to the plant. Mohd Ruhaizie R., Noradillah A.R., Siti Mashalida J. & Siti Aishah M.

Page 5 Langsat Terminal (One) Environmental Auditing & Health Impact Assessment 2011 1.0 INTRODUCTION Langsat Terminal (One) or acronym LgT-1 is one of the oil and gas (O&G) products storages in Tanjung Langsat Industrial Park (TLIP), a gazette industrial area early 1990s. TLIP consist two major areas, which are Tanjung Langsat Industrial Area (TLIA) and Tanjung Langsat Port (TLP). Once fully occupied, both areas will have several industrials such as O&G storages and productions, chemical industries, steel processing industries, wood and timber industries as well as transportation services (see Figure 1-1 – The Zoning in Local Planning of Pasir Gudang Municipal Council By The Year 2020 ). TLIP can be reached via two main land routes either using Pasir Gudang Highway which connecting the metropolitan center of Johor Bahru to Jalan Pekeliling at Pasir Gudang, or from Senai, where the Sultan Ismail International Airport (SIIA) is located via the new route of E22 Senai-Desaru Highway. Both routes are about 50 km each (see Figure 1- 2 – E22 routes by Senai-Desaru Expressway Berhad ). Back to LgT-1, this plant of 476,000 m3 of O&G storages kick off their planning with the Preliminary Environmental Impact Assessment (EIA) written and authorized by the local authorities in 2007. The Environmental Management Plan (EMP) which as planned in the Preliminary EIA was conducted as well as the Environmental Auditing (EA) by a licensed authorized auditor. It consist monthly auditing for the effluent and water quality and every quarter of the year for boundary noise exposure monitoring, air quality monitoring and marine water quality monitoring. The milestone of the EIA processes at LgT-1 is shown as below: Mohd Ruhaizie R., Noradillah A.R., Siti Mashalida J. & Siti Aishah M. Bachelor Degree in Environmental Safety & Health (Hons.)
