  • In January 2009, the Term of Reference (TOR) for the Detailed Environmental Impact Assessment Study (DEIA) was submitted to Department of Environmental Putrajaya (DOE) for approval prior to the commencement of the study. The submission was prepared by EKVESB's Environmental Consultant, UKM Pakarunding (UKMP).

  • In March 2010, EKVESB had submitted the revised Term of Reference to DOE. The revision was mainly due to the changes caused by the alignment modification process requested by the State government.

  • The DEIA study involves the following aspects:-

  • Geology and Geomorphology

  • Soil and Erosion

  • Land Use and Topography

  • Climate and Meteorology

  • Surface Hydrology

  • Water Quality

  • Air Quality

  • Noise

  • Vibration

  • Land Transport Traffic

  • Terrestrial Fauna

  • Terrestrial Herpetofauna

  • Terrestrial Flora

  • Freshwater Ecology

  • Socio-economy

  • Public Health

  • Economic Evaluation of Environmental Impacts

  • Review panellist of DEIA as appointed by DOE consist the following experts and they represented stake-holders from relevant government agencies, non-governmental organisations and professionals. They are as listed in Table 4 and Table 5.

  • Whilst obtaining the approval of TOR, UKMP had proactively started with the study on the ground involving the survey and data collection works.

  • Public dialogs were conducted to gauge the public response especially areas concerning traditional Malay settlements in Sg Pusu, Gombak and Pekan Batu 14, Hulu Langat.

  • In March 2011, TOR was approved and by November 2011 the preparation of DEIA report was completed and submitted to DOE for approval.

  • The advertisement in major dailies such as New Straits Times and Berita Harian was arranged by EKVESB informing the public that the DEIA report is available at all DOE's offices through-out the country for public viewing.

  • Series of panel review meetings and site visits were held then to deliberate on the content of DEIA report.

  • The approval was turned down twice by DOE and the reasons being the study lacking of specific details concerning mitigation steps in dealing with the impacts of oil spillage during highway operation as well as detailed erosion and sediment control plan to be implemented during construction period.

  • Finally after submission of new information to DOE, and subsequently through series of meetings with the panels to review the addendum, the approval was obtained in April 2013 with conditions as summarized below:-

  • Approval of Environmental Management Plan (EMP) prior to commencement of construction works.

  • Preparation of Wildlife Management Plan (EMP) and reviewed by PERHILITAN

  1. Approval of Traffic Management Plan

  2. Preparation of Emergency Response Plan (ERP)

  3. Implementation of Pollutant Removal System (PRS)

  4. Surface water run-off must flow through PRS and the discharge must comply with Standard "A" in "Jadual Kelima di dalam Peraturan-Peraturan Kualiti Alam Sekeliling (Efluen Perindustrian), 2009, P.U(A)434" for oil and grease perimeter and suspended solid before discharge to water course.

  5. Endorsement of Erosion and Sediment Control Plan (ESCP) by DID in accordance to Best Management Practice (BMP)

  6. Temporary slope protection (for erosion) during earthworks

  7. Construction of mainline along "Taman Warisan Selangor" in stages (stretch of 1km) for site clearing in order to minimize the impact to the environment.

  8. Compliance to all ESCP requirements during construction

  9. All discharge must comply to turbidity <250NTU and TSS<50mg/L

  10. To monitor air, noise and vibration in accordance to the requirement

  11. To manage the solid waste in accordance to the requirement

  12. To conduct regular audits by certified environmental auditors

  13. All reporting to DOE shall be as follows:

  • On-line BMPs report if precipitation >12.5mm

  • Progress report every three (3) months until the completion of earthworks

  • Report of compliance to the EIA requirements every three (3) months starting earthworks

  • Monitoring report of sound, vibration and water quality every three (3) months until completion of construction

  • Monitoring report of sound, noise, vibration and PRS every three (3) months during operation

  • The specific measures are required for stretches between Ampang Interchange and Ukay Perdana Interchange because this section of alignment is considered as the most environmentally sensitive area. It is not only a forest reserve but also acts as water catchment area and where Ampang Water Intake is located at.
