Written Notification & Written Declaration

Complying with the Environmental Quality (Clean Air) Regulations (2014) (pdf 2), it is an obligation for a premise to submit Written Notification (Regulation 5) followed by Written Declaration (Regulation 7) prior to:
  • Changes in operation of the premise
  • New source of emission due to any work or facilities on the premise
  • Changes in plant, machine or equipment used or installed at the premises that causes material changes from existing source
  • Changes or modifications to an existing air pollution control system (APCS)

The previous system, Written Approval (Kebenaran Bertulis) is no longer applicable as it was replaced with Written Notification in the Environmental Quality (Clean Air) Regulations (2014). Submission of a Written Notification is compulsory at least 30 days before any work begins at the premise. A Written Declaration is required to be submitted within 30 days after the commencement of operations at the premises, ensuring the design and construction of the APCS complied with the specifications.

Our company is currently focusing on providing assistance in submitting and attaining approval of Written Notification or Written Declaration for Fuel Burning Equipment (FBE) and Air Pollution Control System (APCS).

Fuel Burning Equipment (FBE)

Fuel Burning Equipment can be defined as any equipment, machine or device that is used in the process of burning fuel or other combustible material where the main purpose is producing heat for indirect heat transfer. This includes any facilities that are designed to produce steam (e.g. boilers), furnace, fuel feeding equipment, ducts, breechings, ash removal equipment, combustion controls, stacks and others. Limit values and technical standards of FBE using pulverized fuel:

  • Any solid fuel: ≥ 30 kg/hr
  • Any liquid or gaseous matter: ≥ 15 kg/hr

Currently, we are focusing on the FBE as follows:

  • Boiler
  • Furnace
  • Oven
  • Thermal Oil Heater
  • Kiln

Air Pollution Control System (APCS)

Air pollution is the presence of harmful or poisonous substance into the atmosphere such as particulate matter, Carbon Monoxide (CO), Chlorofluorocarbon (CFC) and others. These pollutants have affected human health, animal, plants as well as causing global warming and acid rain. Therefore, the Air Pollution Control System was introduced as one of the control measures. APCS is a system consists of a set of device or equipment that is designed and installed in order to reduce or eliminate air pollutants emissions to the atmosphere. A complete APCS component consists of ducting, stack, suction hood, fan and air pollution control equipment.

According to DOE, APCS should be compatible with all components of the local exhaust ventilation system where collection rate, capacity and resistance of the air cleaner remain as constant as possible throughout daily operating cycle and be nearly independent of entering dust, fume or vapor concentration. The requirement of APCS is compliance with the Environmental Quality Act 1974 and Clean Air Regulation 2014, under Regulation 7 (APCS) and Regulation 9 (Performance Monitoring of APCS).

Currently, our work is focusing on:

  • Bag Filter Dust Collector
  • Cyclone (Wet and Dry)
  • Scrubber (Wet and Dry)
  • Spray Booth
  • Chimney (Fume Cupboard, Activated Carbon Filter)
  • Electrostatic Precipitator (ESP)
