Just a reference in understanding amendment procedures on regulations in Thailand.

Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH, on behalf of the German Federal Ministry of Economic Affairs and Energy (BMWi), published a position paper entitled’ PV ROOFTOP DEVELOPMENT IN THAILAND Analysis of Regulations and Challenges in March 2015.

They pointed out issues of the Factory Act 1992, managed by the Department of Industrial Works, the Ministry of Industry, which was a barrier to prevent from installation of solar power system.

The report strongly claimed that it is advised to define clear requirements, procedures and deadlines for obtaining the factory operation license. The information should be made publically available and equally known to all involved stakeholders. In addition, procedures, requirements and deadlines should be applied transparently and uniformly by the competent authorities.

Some remarkable improvements have been made thanks to the position paper.

It seems to me that procedures of amendment for Hazardous Substance Act should be followed the successful path of the Factory Act.
