I believe it is rarely known that the concept of “environmental personnel” at factories in Thailand has its root in Japan. In 1971, the Japanese government enacted the Law Concerning the Improvement of Pollution Prevention Systems in Specific Factories, which required specified factories to set up a pollution control manager system composed of a pollution control supervisor who oversees pollution prevention duties, pollution control chief managers who support the pollution control supervisor, and pollution control managers who have technical and professional knowledge and skills in topics of air, water, noise, vibration and dioxin pollution. Such an organizational system has allowed target factories to develop personnel responsible for pollution control who are capable of performing daily tasks and maintaining a good relation with authorities and local residents. This policy played a significant role to improve the compliance rate in terms of environmental regulations among factories in Japan during 1970s–1980s.

 

In Thailand, such experiences in Japan had been well recorded, presented and demonstrated in various occasions and the Ministry of Industry of Thailand has adopted the similar pollution control manager system since the year 2002. To date, eight regulations have been released and such a pollution control system has become one of the most important environmental regulations that all factories must observe. This article will discuss each of the eight regulations in the chronological order of legislation.

 

1. Ministry of Industry Notification on Designation of Factory Types and Sizes, Procedure for the Control of Discharges of Wastes, Pollutants, or Any Substances that Cause Adverse Effects on the Environment, Qualifications of Supervisors and Operators, and Criteria for Registration of the Supervisors of Pollution Prevention Systems B.E. 2545 (2002).

  • This regulation establishes principles for environmental personnel in factories composed of
    • “Pollution control supervisor” which is classified as: “environmental manager” “water pollution supervisor” “air pollution supervisor” and “waste management supervisor”
    • “Pollution control system operator”
    • “Consultant” who is a service provision contractor permitted to serve as a supervisor

    • “Water pollution supervisor” “air pollution supervisor” “waste management supervisor” and “consultant” are responsible for assessment and inspection of pollutants’ characteristics and the efficiency of pollution prevention system and prevent pollutants from being discharged into the environment without passing through the pollution prevention system as well as to prepare pollutant analysis reports.
    • “operator” is responsible for the operation of machines under the pollution prevention system.
  • The factory shall control of discharges of wastes, pollutants or any substances that cause adverse effects on the environment by employing environmental personnel and submit application for permission to have environmental personnel according to the criteria defined by the Department of Industrial Works.
  • This regulation also gives criteria for registration of environmental personnel, renewal of license, revocation of license and format of application form.

3. Department of Industrial Works Notification on Qualification, Training and Standard Examination of Environmental Personnel in Factory B.E. 2554 (2011).

  • Stipulates matters on the qualification of environmental personnel in factories. For example, “environmental manager” must be an employee at a factory in managing level who have completed an environmental manager training course and “pollution supervisor” must have at least bachelor degree in a related field and passed a qualification examination and be registered with Department of Industrial Works.
    • Stipulates qualification requirements for training agencies which must be a legal personnel under Thailand laws and regulations with an experience on industrial environment and pollution training for at least 2 years with personnel qualified to be trainers.

    • Factory having or using VOCs in production processes from 36 tons/year.
  • Uses a regulatory concept taken from PRTR to estimate the amount of pollution to be reported by environmental personnel in the report. Type and amount of pollutants can be estimated and reported by two methods: “Group M” (Measurement) which refers to data of type and amount of pollutants retrieved from measurements and analyzed with a reference standard method; and “Group C” (Calculation) which refers to data of type and amount of pollutants retrieved using an internationally-accepted calculation method, namely one of the following: a) emission factors of such pollutants b) engineering calculation; or c) mass balance.
  • Designates pollutants that should be analyzed in terms of factory effluent and emission. For example, in most cases, factories should analyze for BOD, COD, pH, and suspended solids of their effluent; and in some cases, they should analyze heavy metals and other parameters. They also should analyze for oxide of nitrogen, sulfur dioxide and total suspended particulate in emission gases, with carbon monoxide in some cases.
  • Stipulates a format for report on type and amount of pollutants compilation which must be done by environmental personnel and that the report should be submitted to the Department of Industrial Works online. The first report, comprising the data from January to June, shall be submitted by September 1st of the reporting year; and the second report, comprising the data from July to December, shall be submitted by March 1st of the following year.

7. Department of Industrial Works Notification on Report Form of Type and Amount of Pollutants Discharged From a Factory B.E. 2559 (2016).
This regulation designate form for emission report namely

  • RoWo. 3 Form: for air pollution report

8. Department of Industrial Works Notification on Registration of Water pollution Supervisor, Air Pollution Supervisor and Waste Management Supervisor No.2 B.E. 2564 (2021). This regulation modifies Department of Industrial Works Notification on Registration of Water pollution Supervisor, Air Pollution Supervisor and Waste Management Supervisor B.E. 2556 (2013) such that registration of pollution supervisor can be done online.

Currently there are 12 institutes registered as a qualified training agency and 2 institutes registered as an examination agency. In 19 years from the beginning, regulations on environmental personnel in Thailand’s factories have evolved. Currently, most of individuals who major in environmental sciences are encouraged to take the pollution supervisor qualification examination before their graduation since such certificate will increase a chance of getting job in factory.
