Abstract: There is a need to ensure long-term security for the supply of rock aggregates in Selangor, in view of the impending implementation of the Selangor Policy on Environmentally Sensitive Areas (ESAs). Preliminary findings from a case study of rock aggregates in Eastern Selangor reveal that six quarries and 66% of new aggregate resources in the state are located in highly sensitive ESAs, which are categorised as “no go areas” for quarrying. At least ten quarries and another 26% of new resources are located in ESAs of medium and low sensitivity, which are areas of “controlled development” requiring special circumstances and very strict conditions for quarrying. Only 8% of the new resources identified are actually available for exploitation in the future. Aggregate landbanks and buffer zones should be delineated and gazette in local development plans and efforts should be made to thoroughly investigate potential resources outside of the ESAs. This effort should be augmented by the promotion of recycled concrete aggregates to maintain aggregate security and ensure sustainable development.

Abstrak- Perlaksanaan Dasar Kawasan Sensitif Alam Sekitar (KSAS) Selangor dijangka menjejas jaminan bekalan batuan agregat di negeri tersebut. Hasil awalan kajian kes di bahagian timur Selangor mendapati bahawa terdapat enam kuari dan 66% daripada sumber aggregat baru yang bertapak di KSAS berkesensitifan tinggi yang melarang kegiatan pengkuarian. Hampir 10 kuari dan 26% daripada sumber aggregat baru pula bertapak di KSAS berkesensitifan sederhana dan rendah yang merupakan kawasan pembangunan terkawal di mana kebenaran khas diperlukan untuk kegiatan pengkuarian dan syaratnya amat ketat. Hanya 8% daripada sumber aggregate baru yang telah dikenalpasti boleh dieksploitasi di masa depan. Tabung tanah dan zon penampan aggregate perlu dikenalpasti dan digazetkan dalam pelan pembangunan tempatan manakala usaha perlu ditingkatkan bagi merisik potensi sumber tersebut di luar KSAS. Selain itu, penggunaan agregat konkrit terkitar perlu dipromosikan bagi menjamin bekalan aggregate dan pembangunan mampan.
